| + | # Administrative and Tools |
| + | |
| + | Akcel Systems Inc. provides the tools and administrative systems necessary for our team to perform their jobs effectively. Proper use and care of these resources are the responsibility of every employee. |
| + | |
| + | ## Time Tracking (Service Fusion) |
| + | |
| + | Service Fusion is our system of record for all labor time. Accurate time tracking is essential for project costing, service billing, and payroll. |
| + | |
| + | * **Daily Requirements:** |
| + | * Every field visit must be logged in real-time. |
| + | * Start and end times must be recorded by updating job status (Started → Completed). |
| + | * Drive time is automatically tracked between "On the Way" and "On Site" status changes. |
| + | * **Non-Productive Time:** Any time not directly related to a project or service call (training, shop time, vehicle maintenance) must be logged according to company standards. |
| + | * **Accuracy:** Time entries must match actual work performed. Misrepresenting time is a serious violation of company policy. |
| + | |
| + | ## Vehicle and Tool Procedures |
| + | |
| + | * **Company Vehicles:** If you are assigned a company vehicle, you are responsible for its safe operation and routine maintenance. Follow all traffic laws and maintain a clean vehicle. |
| + | * **Tool Sign-Out:** Essential hand tools and specialized test equipment (Air Hood, network testers) are issued by the Warehouse Manager. All equipment must be signed out and returned in good working condition. |
| + | * **Maintenance:** Inspect your tools regularly. Report any damaged or malfunctioning equipment to the Warehouse Manager or your supervisor immediately. Do not use damaged tools. |
| + | * **Inventory:** You are responsible for the inventory of parts and materials on your vehicle. Log all items used in Service Fusion to ensure accurate stock levels. |
| + | |
| + | ## Payroll and Benefits (Overview) |
| + | |
| + | Akcel Systems Inc. offers competitive compensation and benefits designed to support our team members and their families. |
| + | |
| + | * **Payroll:** Employees are paid [Weekly/Bi-weekly] through [Direct Deposit/Check]. |
| + | * **Benefits:** Eligible employees may receive benefits including: |
| + | * Health, dental, and vision insurance. |
| + | * Retirement savings plan (401k). |
| + | * Paid time off (PTO) and holidays: |
| + | * 14 sick days per year. |
| + | * 30 days of vacation per year. |
| + | * Continuing education reimbursement (as approved by management). |
| + | * **Questions:** Please contact the **Accountant** or Human Resources for specific questions regarding your payroll or benefits package. |
| + | |
| + | ## Reporting and Documentation |
| + | |
| + | * **Daily Field Reports (DFRs):** Required for every installation task. DFRs must include work performed, materials used, and any site issues or safety concerns. |
| + | * **Completion Notes:** Comprehensive completion notes are required for every service call before the ticket can be closed. |
| + | * **Expense Reporting:** All out-of-pocket expenses (parking, tolls, supplies) must be logged in Service Fusion with digital copies of receipts attached. |
| + | |

| + | # Project Management Gamification System: Internal Market Model |
| + | |
| + | **Revision:** 1.1 (Scalable Framework) |
| + | |
| + | --- |
| + | |
| + | ## 1. Executive Summary |
| + | |
| + | This document defines an internal "Micro-Economy" designed to align **Project Management (PM) Strategy** with **Technical Execution**. By treating time as a finite commodity and labor as a salary-plus-incentive model, the organization fosters a meritocracy where Efficiency, Quality, and Mentorship are the primary drivers of financial reward. |
| + | |
| + | --- |
| + | |
| + | ## 2. The Payout Architecture: Individual vs. Collective |
| + | |
| + | The system utilizes a split weight ($W$) to balance individual managerial accountability with collective technician stability. |
| + | |
| + | ### 2.1 The PM Individual "Equity" ($W_{pm}$) |
| + | |
| + | Each PM operates an independent budget. At the end of the fiscal year, their personal bonus base is determined by their specific remaining surplus. |
| + | |
| + | $$B_{pm} = (S_{pm} \cdot W_{pm}) \cdot M_{pm}$$ |
| + | |
| + | **Legend:** |
| + | - $B_{pm}$: Individual Project Manager Bonus. |
| + | - $S_{pm}$: Total annual budget surplus managed by the specific PM. |
| + | - $W_{pm}$: PM Equity weight (Standard: 0.25). |
| + | - $M_{pm}$: Individual PM Multiplier (Performance Score). |
| + | |
| + | ### 2.2 The Technician "Collective Fund" ($W_{tech}$) |
| + | |
| + | To protect technicians from being penalized for working with an inefficient manager, the majority share of surplus from all PMs is diverted into a central pool. |
| + | |
| + | $$B_{tech} = \left( \frac{\sum_{i=1}^{N_{pm}} (S_{pm, i} \cdot W_{tech})}{N_{tech}} \right) \cdot M_{tech}$$ |
| + | |
| + | **Legend:** |
| + | - $B_{tech}$: Individual Technician Bonus. |
| + | - $S_{pm, i}$: Budget surplus of PM $i$. |
| + | - $W_{tech}$: Technician Collective weight (Standard: 0.75). |
| + | - $N_{pm}$: Total number of Project Managers in the organization. |
| + | - $N_{tech}$: Total number of Technicians in the collective pool. |
| + | - $M_{tech}$: Individual Technician Multiplier (Performance Score). |
| + | |
| + | --- |
| + | |
| + | ## 3. Market Mechanics & Labor Pricing |
| + | |
| + | ### 3.1 Role Categories & The 3-Tier System |
| + | |
| + | Each role in the organization operates on a **3-Tier Progression**, directly tied to the [Training Structure](Training Structure/Roles/). |
| + | |
| + | - **Tier 1 (Junior/Apprentice):** Currently working through "Key Tasks for Qualification." High supervision required. |
| + | - **Tier 2 (Qualified/Standard):** Has completed qualification checklists and written exams. Independent operator. |
| + | - **Tier 3 (Senior/Lead):** Has completed "Advanced Training," achieved certifications, and is actively mentoring Tier 1 staff. |
| + | |
| + | #### 3.1.1 Resource Constraints |
| + | - **Workforce Variables:** |
| + | - $N_{pm}$: Total Project Managers. |
| + | - $N_{tech}$: Total Technicians ($N_{t1} + N_{t2} + N_{t3}$). |
| + | - $C_{tech}$: Monthly hour capacity per technician (Standard: 160h). |
| + | - **PM Monthly Reset ($R$):** Monthly credit allotment adjusted by PM Tier. |
| + | - Tier 1 PM: $R_{base} \cdot 0.8$ |
| + | - Tier 2 PM: $R_{base} \cdot 1.0$ |
| + | - Tier 3 PM: $R_{base} \cdot 1.2$ |
| + | |
| + | ### 3.2 Dual-Constraint Pricing ($P_{h}$) |
| + | |
| + | Labor costs fluctuate based on the intersection of **Time ($T$)** (proximity to month-end) and **Scarcity ($S$)** (remaining hours in the Office "vault"). |
| + | |
| + | $$P_h = P_{base} \cdot (1 + T_{factor} + S_{factor})$$ |
| + | |
| + | **Legend:** |
| + | - $P_h$: Current Market Hourly Rate. |
| + | - $P_{base}$: Base Hourly Rate (defined by Role/Tier). |
| + | - $T_{factor}$: Time-to-Deadline factor (increases as month-end approaches). |
| + | - $S_{factor}$: Scarcity factor (increases as total office hours in "The Vault" decrease). |
| + | |
| + | |**Role Category**|**Tier 1 (Junior)**|**Tier 2 (Standard)**|**Tier 3 (Lead)**|**Risk Profile**| |
| + | |---|---|---|---|---| |
| + | |**Specialists**|$120 / hr|$150 / hr|$180 / hr|0% to 5% Rework Risk| |
| + | |**Field Specialists**|$80 / hr|$100 / hr|$120 / hr|5% to 15% Rework Risk| |
| + | |**Installers**|$40 / hr|$60 / hr|$80 / hr|10% to 25% Rework Risk| |
| + | |
| + | --- |
| + | |
| + | ## 4. Performance Metrics & Multipliers |
| + | |
| + | Final payouts are adjusted by a multiplier ($M$) ranging from **0.5x to 1.5x**. |
| + | |
| + | ### 4.1 Project Manager Multiplier ($M_{pm}$) |
| + | |
| + | $$M_{pm} = (P_{score} \cdot 0.50) + (E_{market} \cdot 0.20) + (D_{mix} \cdot 0.15) + (R_{penalty} \cdot 0.15)$$ |
| + | |
| + | **Legend:** |
| + | - $P_{score}$: Progress Score (Percentage of milestones met). |
| + | - $E_{market}$: Market Efficiency (Success in buying hours before scarcity spikes). |
| + | - $D_{mix}$: Diversity Mix (Effective utilization of Tier 1 talent). |
| + | - $R_{penalty}$: Rework Penalty (PMs pay Double Market Rate for rework hours). |
| + | |
| + | ### 4.2 Technician Multiplier ($M_{tech}$) |
| + | |
| + | $$M_{tech} = (Q_{score} \cdot 0.40) + (V_{speed} \cdot 0.30) + (Ment_{bonus} \cdot 0.20) + (S_{duty} \cdot 0.10)$$ |
| + | |
| + | **Legend:** |
| + | - $Q_{score}$: Quality Score ($1.0 - (\text{Rework Incidents} \cdot \text{Tier Penalty})$). |
| + | - $V_{speed}$: Velocity Score ($\frac{\text{Allotted Hours}}{\text{Actual Hours Worked}}$). |
| + | - $Ment_{bonus}$: Mentorship Bonus (Tier 3 Only - speed of Junior qualification). |
| + | - $S_{duty}$: Duty Reliability (Safety and site rotation adherence). |
| + | |
| + | --- |
| + | |
| + | ## 5. Operational Protocols: The "Allotment Wall" |
| + | |
| + | - **The Wall:** If a technician reaches the allotted time but the task is unfinished, they **must stop**. The PM must approve and "buy" more time at current market rates ($P_h$) to proceed. |
| + | - **Underrun:** If a technician finishes early, they earn "Free Time" (paid for full allotment). |
| + | - **Tiered Audits:** 10% of tasks undergo a random Quality Audit. |
| + | - Tier 1 tasks are audited by Tier 3 technicians. |
| + | - Tier 3 tasks are audited by the **Senior Field Operations Coordinator**. |
| + | - **Market Support Roles:** |
| + | - **Accountant:** Reconciles the Collective Fund and validates $R_{penalty}$ triggers. |
| + | - **Warehouse Manager:** Controls "Material Liquidity." |
| + | - **Senior Coordinator:** The "Market Maker" who manages the dispatch queue and surge pricing. |
| + | |
| + | --- |
| + | |
| + | ## 6. Conclusion |
| + | |
| + | This framework eliminates the traditional friction between "speed" and "quality."

| + | |
| + | **Version:** 1.0 |
| + | **Date:** 2025-12-29 |
| + | **Author:** Gemini Agent |
| + | **Related SSO:** [[SSO Temp Sensor]], [[SSO Pressure Sensor]], [[SSO Flow Switch]], [[SSO Valve Actuator]], [[SSO Relay Output]] |
| + | |
| + | --- |
| + | |
| + | ## 1. Overview |
| + | This document outlines the sequence of operation for the Glycol Chilled Water System (CHWS). This is a manually-started system during the cooling season, featuring monitoring and control of multiple chilled water pumps, chillers, and associated glycol make-up units. |
| + | |
| + | The system's primary automated functions are: |
| + | 1. **System Monitoring & Alarming**: Upon manual activation, the control panel actively monitors pump status, water flow, temperatures, and pressures. It generates alarms for any out-of-spec conditions, including pump failure, loss of flow, or abnormal temperatures. |
| + | 2. **Differential Pressure Control**: A differential pressure transmitter located in the main piping loop continuously modulates a bypass valve to maintain a constant differential pressure between the supply and return mains. |
| + | 3. **Glycol Make-up Automation**: Dedicated glycol make-up pump systems automatically maintain pressure in their associated loops. The pump activates to build pressure and deactivates upon reaching the setpoint, with full safety and level monitoring alarms. |
| + | |
| + | The system is managed by two `ECL-650` controllers, which handle specific pumps, fans, and chillers but share common system sensors. |
| + | |
| + | --- |
| + | |
| + | ## 2. Point List |

| + | |
| + | --- |
| + | |
| + | ## 3. Safety Devices & Interlocks |
| + | - **Glycol Pump Pressure Safety**: The glycol make-up pump will be de-energized if the system pressure drops below a low-low limit setpoint (`GCHW-Press-LOLMT`) or rises above a high-high limit setpoint (`GCHW-Press-HILMT`). An alarm is generated in both cases. |
| + | - **Glycol Pump Start Failure**: If a make-up pump is commanded ON (`P-3-C` or `P-6-C`) but its corresponding status contact (`P-3-S` or `P-6-S`) does not prove flow within a defined time, the pump command will be stopped and a malfunction alarm will be generated. |
| + | - **Glycol Tank Low Level**: If the glycol tank low level float switch (`GT-LL-A`) activates, the associated make-up pump will be stopped, and an alarm will be generated to prevent the pump from running dry. |
| + | |
| + | --- |
| + | |
| + | ## 4. Modes of Operation |
| + | |
| + | ### Chilled Water System Operation |
| + | - **Activation**: The chilled water pumps (`P-1`, `P-2`, `P-4`, `P-5`) and chillers are started **manually** for the cooling season. |
| + | - **Monitoring**: Once the system is active, the DDC controller monitors all associated points. All alarm functions become active. |
| + | - **Differential Pressure Control**: |
| + | - The `GCHW-DP` transmitter continuously measures the differential pressure across the supply and return mains. |
| + | - The controller modulates the normally open bypass valve (`CHWS-BYP-VLV1-O` / `GCHWP-BYP-O`) to maintain the `GCHW-DP-SP`. |
| + | - As system load increases (VAV boxes open), system DP will tend to drop, causing the bypass valve to modulate closed to force more flow out to the system. |
| + | - As system load decreases (VAV boxes close), system DP will tend to rise, causing the bypass valve to modulate open to relieve pressure. |
| + | |
| + | ### Glycol Make-up Pumps (Typical of P-3, P-6) |
| + | - **Monitoring**: The analog pressure transmitter in the expansion tank feed line is continuously monitored. |

| + | # Glycol Hot Water System (HWS) - Sequence of Operation |
| + | |
| + | **Version:** 1.0 |
| + | **Date:** 2025-12-29 |
| + | **Author:** Gemini Agent |
| + | **Related SSO:** [[SSO Temp Sensor]], [[SSO Pressure Sensor]], [[SSO Valve Actuator]], [[SSO Relay Output]] |
| + | |
| + | --- |
| + | |
| + | ## 1. Overview |
| + | This document outlines the sequence of operation for the Glycol Hot Water System (HWS), which provides heating capacity to the facility. The system initiates operation either automatically based on outside air temperature (OAT) conditions or via manual activation from the User workstation. |
| + | |
| + | Key functions of this system include: |
| + | 1. **System Activation & Temperature Control**: Hot water pumps are started, and upon proving operation, heat exchanger valves modulate to maintain a hot water supply temperature setpoint. This setpoint dynamically resets as a function of OAT to optimize energy usage. |
| + | 2. **Differential Pressure Control**: A differential pressure transmitter located in the main hot water supply piping modulates a bypass valve to ensure a constant differential pressure is maintained across the supply and return mains. |
| + | 3. **Glycol Make-up Automation**: An integrated glycol make-up pump system automatically monitors and maintains the system pressure, activating the pump when necessary and ensuring safe operation with various pressure and level alarms. |
| + | |
| + | The system is controlled by an `ECL-650` controller, which monitors and manages all associated points and alarms. |
| + | |
| + | --- |
| + | |
| + | ## 2. Point List |
| + | ### Inputs (Physical) |
| + | - **Hot Water Pump 7 Status (P-7-S)**: BI (ECL-650, UI1), Dry Contact |
| + | - **Hot Water Pump 8 Status (P-8-S)**: BI (ECL-650, UI2), Dry Contact |
| + | - **Glycol Tank Low Level Alarm (GT-LL-A)**: BI (ECL-650, UI3), Dry Contact |
| + | - **Hot Water Pump 9 Status (P-9-S)**: BI (ECL-650, UI4), Dry Contact |
| + | - **Glycol Hot Water Differential Pressure Transducer (HWS-DP)**: AI (ECL-650, UI5), 0-10VDC |
| + | - **Hot Water Supply Temperature (HWS-T)**: AI (ECL-650, UI6), 1K RTD |
| + | - **Hot Water Return Temperature (HWR-T)**: AI (ECL-650, UI7), 1K RTD |
| + | |
| + | ### Outputs (Physical) |
| + | - **Hot Water Pump 7 Command (P-7-C)**: BO (ECL-650, UO1), 12 VDC |
| + | - **Hot Water Pump 8 Command (P-8-C)**: BO (ECL-650, UO2), 12 VDC |
| + | - **Hot Water Pump 9 Command (P-9-C)**: BO (ECL-650, UO3), 12 VDC |
| + | - **Glycol Hot Water Bypass Valve Output (HW-BYP-VLV-O)**: AO (ECL-650, UO4), 0-10VDC |
| + | - **Heat Exchanger Control Valve 1 Output (HX-1-O)**: AO (ECL-650, UO5), 0-10VDC |
| + | - **Heat Exchanger Control Valve 2 Output (HX-2-O)**: AO (ECL-650, UO6), 0-10VDC |
| + | |
| + | ### Software Points & Setpoints |
| + | - **Heat Exchanger Differential Pressure Setpoint (HX-1-DP-SP)**: Setpoint (Software) |
| + | - **Hot Water Supply Temperature Setpoint (HWS-SP)**: Setpoint (Software) |
| + | - **Hot Water System ON/OFF Command (HWS-RUN)**: Software (from User Workstation or OAT) |
| + | - **Outside Air Temperature (OAT)**: AI (Networked or Local) |
| + | - **Hot Water Supply Temp High Limit Alarm (HWS-T-HILMT)**: Setpoint (Software) |
| + | - **Hot Water Supply Temp Low Limit Alarm (HWS-T-LOLMT)**: Setpoint (Software) |
| + | - **Glycol System Normal Operating Pressure (GCHW-Press-SP)**: Setpoint (Software) |
| + | - **Glycol System Low-Low Pressure Alarm Limit (GCHW-Press-LOLMT)**: Setpoint (Software) |
| + | - **Glycol System High-High Pressure Alarm Limit (GCHW-Press-HILMT)**: Setpoint (Software) |
| + | |
| + | --- |
| + | |
| + | ## 3. Safety Devices & Interlocks |
| + | - **System Activation Interlock**: Heat exchanger valves (`HX-1-O`, `HX-2-O`) will only be activated upon confirmation of operation (`P-7-S`, `P-8-S`, `P-9-S`) of the associated hot water pumps. |
| + | - **Glycol Pump Pressure Safety**: The glycol make-up pump (P-9) will be de-energized if the system pressure drops below a low-low limit setpoint (`GCHW-Press-LOLMT`) or rises above a high-high limit setpoint (`GCHW-Press-HILMT`). An alarm is generated in both cases. |
| + | - **Glycol Pump Start Failure**: If the make-up pump (P-9) is commanded ON (`P-9-C`) but its corresponding status contact (`P-9-S`) does not prove operation within a defined time, the pump command will be stopped and a malfunction alarm will be generated. |
| + | - **Glycol Tank Low Level**: If the glycol tank low level float switch (`GT-LL-A`) activates, the associated make-up pump (P-9) will be stopped, and an alarm will be generated to prevent the pump from running dry. |
| + | |
| + | --- |
| + | |
| + | ## 4. Modes of Operation |
| + | |
| + | ### Hot Water System Start/Stop |
| + | - **System Start Conditions**: |
| + | - **Automatic**: Outside Air Temperature (`OAT`) drops below 60°F (adjustable). |
| + | - **Manual**: Activated via the User workstation (`HWS-RUN`). |
| + | - **System Stop Conditions**: |
| + | - **Automatic**: Outside Air Temperature (`OAT`) rises above 60°F (adjustable) AND `HWS-RUN` is OFF. |
| + | - **Manual**: Deactivated via the User workstation (`HWS-RUN`). |
| + | - **Start Sequence**: |
| + | 1. Upon start condition, hot water pumps (`P-7-C`, `P-8-C`, `P-9-C`) are commanded ON. |
| + | 2. Upon confirmation of pump operation (via `P-7-S`, `P-8-S`, `P-9-S` auxiliary contacts), heat exchanger valves (`HX-1-O`, `HX-2-O`) are activated. |
| + | |
| + | ### Hot Water Supply Temperature Control |
| + | - **Objective**: Maintain `HWS-T` at `HWS-SP`. |
| + | - **Control Action**: The one-third two-third steam control valves (implied by `HX-1-O`, `HX-2-O`) will be modulated, in sequence, to maintain the desired `HWS-SP`. |
| + | - **Setpoint Reset Schedule**: The `HWS-SP` will be reset as a function of `OAT` in accordance with the following schedule (user adjustable): |
| + | - **OAT < 20°F**: `HWS-SP` = 180°F |
| + | - **OAT = 40°F**: `HWS-SP` = 160°F |
| + | - **OAT > 60°F**: `HWS-SP` = 140°F (Minimum setpoint, system likely OFF) |
| + | - Linear interpolation between these points. |
| + | |
| + | ### Hot Water Differential Pressure Control |
| + | - **Objective**: Maintain a constant differential pressure (`HWS-DP`) across the hot water supply and hot water return mains. |
| + | - **Control Action**: The `HWS-DP` transmitter modulates the normally open hot water differential pressure bypass valve (`HW-BYP-VLV-O`). |
| + | - If `HWS-DP` drops below its setpoint, the bypass valve modulates closed. |
| + | - If `HWS-DP` rises above its setpoint, the bypass valve modulates open. |
| + | |
| + | ### Glycol Make-up Pump (P-9) Control |
| + | - **Monitoring**: An analog pressure transmitter (assumed part of `HWS-DP` or a separate sensor) in the expansion tank feed line continuously monitors system pressure. |
| + | - **Pump Activation**: If system pressure drops below the `GCHW-Press-SP`, the glycol make-up pump (P-9, commanded via `P-9-C`) is activated. |
| + | - **Pump Deactivation**: The pump runs continuously until system pressure rises to meet or exceed the `GCHW-Press-SP`. |
| + | - **Safety Stop**: The pump is stopped if system pressure drops below `GCHW-Press-LOLMT` or rises above `GCHW-Press-HILMT`. |
| + | |
| + | --- |
| + | |
| + | ## 5. Alarms & Fault Conditions |
| + | All alarms shall be annunciated at the User workstation. |
| + | - **Hot Water Pump Failure**: |
| + | - **Condition**: Status contact (`P-7-S`, `P-8-S`, `P-9-S`) indicates a pump is off when it should be running. |
| + | - **Priority**: High. |
| + | - **Hot Water Supply Temperature Out of Range**: |
| + | - **Condition**: The `HWS-T` reading exceeds the high (`HWS-T-HILMT`) or low (`HWS-T-LOLMT`) alarm limits. |
| + | - **Priority**: Medium. |
| + | - **Glycol Pump Pressure Alarm**: |
| + | - **Condition**: System pressure drops below `GCHW-Press-LOLMT` or rises above `GCHW-Press-HILMT`. |
| + | - **Priority**: High. |
| + | - **Glycol Pump Malfunction**: |
| + | - **Condition**: The glycol make-up pump (P-9) fails to prove status after being commanded ON. |
| + | - **Priority**: High. |
| + | - **Glycol Tank Low Level**: |
| + | - **Condition**: The low level float switch (`GT-LL-A`) is activated. |
| + | - **Priority**: Critical. Prevents pump operation. |
| + | |

| + | |
| + | ## 1. Overview |
| + | This sequence describes a non-fan-powered, cooling-only Variable Air Volume (VAV) box with electric reheat controlled by a BACnet DDC controller. The VAV box works in conjunction with a Multi-Zone VAV (MZVAV) rooftop heat pump for cooling and a local electric baseboard for heating. The system utilizes space temperature and CO2 sensors for demand-controlled ventilation (DCV) and thermal comfort, participating in pre-occupied pull-down/purge cycles and unoccupied nighttime purge cycles. The VAV box reports its damper position for supply fan static pressure reset logic and is designed for 24/7 ventilation, with DCV being disabled during special ventilation modes. Electric baseboard heating is enabled only during Winter mode. |

| + | - **CO2 Full Occupancy Threshold**: 1,000 ppm `Fixed` |
| + | - **Vacant Standby Ventilation Rate**: From Drawing Schedules `Configurable` |
| + | - **Fully Occupied Ventilation Rate**: From Drawing Schedules `Configurable` |
| + | - **VAV Damper Position Polling Request**: Software Point (Internal) |
| + | |
| + | --- |
| + | |
| + | ## 3. Operational Notes & Interlocks |
| + | - **Special Ventilation Mode**: When active, Demand Controlled Ventilation (DCV) is disabled. |
| + | - **Static Pressure Reset**: VAV damper position is polled every 10 minutes and reported to the central unit to be used in the supply fan static pressure reset algorithm. |
| + | |
| + | --- |
| + | |
| + | ## 4. Modes of Operation |
| + | |
| + | ### Unoccupied Mode |
| + | - **Conditions**: Entered when the building schedule is "Unoccupied" (excluding purge cycles). Ventilation is provided 24/7. |
| + | - **Heating Logic**: |
| + | - VAV damper is commanded **Closed**. |
| + | - If `Seasonal_Mode` is `Winter`: Electric baseboard is cycled On/Off to maintain the **Unoccupied Heating Setpoint (55°F - 2°F differential)**. |
| + | - If `Seasonal_Mode` is `Summer`: Electric baseboard is disabled. |
| + | - **Cooling Logic**: |
| + | - If the representative room temperature is ≤ 85°F, VAV damper is commanded **Closed**. |
| + | - If the representative room temperature is > 85°F, VAV damper opens to the **Fully Occupied Ventilation Rate** position. The central MZVAV unit stages to cool the space until the representative temperature reaches the **Unoccupied Cooling Cutout (83°F)**. |
| + | |
| + | ### Warm-up Cycle (Optimum Start) |
| + | - **Conditions**: Active before scheduled occupancy if the representative room temperature is below the **Warm-up Cutout Setpoint (72°F)**. Start time is optimized based on outdoor air temperature and space temperature. |
| + | - **Logic**: |
| + | - VAV damper opens to the **Fully Occupied Ventilation Rate**. |
| + | - Central MZVAV unit provides **85°F discharge air** until the representative room reaches 72°F. |
| + | - Electric baseboard setpoint is maintained at **55°F** (regardless of Seasonal Mode for warm-up period). |
| + | |
| + | ### Pre-Occupied & Purge Cycles |
| + | - **Conditions**: Triggered by specific `Building_Schedule` modes prior to or during unoccupied periods. |
| + | - **Pre-Occupied Morning Pull-Down Cycle**: |
| + | - VAV boxes are commanded to their **Fully Occupied Ventilation Rate** positions. |
| + | - Space temperatures are pulled down from **Pre-Occupied Pull-Down Max Temp (85°F - 2°F differential)** to **Pre-Occupied Pull-Down Target Temp (78°F - 2°F differential)**. |
| + | - **Pre-Occupied Morning Purge Cycle**: |
| + | - VAV boxes are commanded to their **Fully Occupied Ventilation Rate** positions. |
| + | - **Unoccupied Nighttime Purge Cycle**: |
| + | - VAV boxes are commanded to their **Fully Occupied Ventilation Rate** positions. |
| + | |
| + | ### Occupied Mode |
| + | - **Conditions**: Entered when the building schedule is "Occupied." |
| + | - **Ventilation Logic (DCV)**: |
| + | - The VAV box minimum flow setpoint is actively reset based on space CO2 levels. |
| + | - The required ventilation rate is calculated via linear interpolation between the **Vacant Standby** rate (at 0 ppm differential) and the **Fully Occupied** rate (at 1,000 ppm). |
| + | - The VAV damper will **never throttle below the Fully Occupied Ventilation Rate**. |
| + | - **Heating Logic**: |
| + | - VAV damper maintains its active minimum airflow setting as determined by DCV. |
| + | - If `Seasonal_Mode` is `Winter`: If Space Temperature drops below **Occupied Heating Setpoint (72°F - 2°F differential)**, the electric baseboard is commanded **ON**. If Space Temperature rises above 72°F, the baseboard is commanded **OFF**. |
| + | - If `Seasonal_Mode` is `Summer`: Electric baseboard is disabled. |
| + | - **Cooling Logic**: |
| + | - If Space Temperature rises above **Occupied Cooling Setpoint (78°F)**, the VAV damper modulates from its current minimum position towards 100% open to meet the load. |
| + | - If Space Temperature drops below 78°F, the damper modulates back towards its active minimum position. |
| + | - **Economizer Logic**: |
| + | - When the central system is in economizer mode, DCV is suspended. |
| + | - The VAV damper modulates between the **Fully Occupied Ventilation Rate** and maximum flow to meet cooling demand. |
| + | |
| + | --- |
| + | |
| + | ## 5. Alarms & Fault Conditions |
| + | - **Excessive Reset Driver Alarm (Static_Reset_Alarm)** |
| + | - **Condition**: The control algorithm automatically detects that this zone is excessively driving the static pressure reset logic. |
| + | - **Priority**: Medium |
| + | - **Action**: Generate an alarm to the system operator, allowing for manual removal of the zone from the reset algorithm. |
| + | - **Reset**: Manual. |
| + | |
| + | --- |
| + | |
| + | ## 6. Commissioning & Verification Checklist |
| + | - [ ] Verify VAV damper closes during Unoccupied mode when temperatures are between 55°F and 85°F. |
| + | - [ ] Verify electric baseboard maintains 55°F during Unoccupied Heating when `Seasonal_Mode` is `Winter`. |
| + | - [ ] Verify electric baseboard remains OFF during Unoccupied Heating when `Seasonal_Mode` is `Summer`. |
| + | - [ ] Verify VAV damper opens and MZVAV cools during Unoccupied Cooling when representative temperature exceeds 85°F. |
| + | - [ ] Verify Warm-up cycle initiates correctly, opening the damper and commanding the baseboard setpoint to 55°F. |
| + | - [ ] Verify Pre-Occupied Morning Pull-Down cycle commands VAV to fully occupied ventilation and space temperature pulls down from 85°F to 78°F. |
| + | - [ ] Verify Pre-Occupied Morning Purge and Unoccupied Nighttime Purge cycles command VAV to fully occupied ventilation. |
| + | - [ ] Verify in Occupied Mode that the damper modulates to maintain the 78°F cooling setpoint. |
| + | - [ ] Verify in Occupied Mode that the electric baseboard turns on to maintain the 72°F heating setpoint when `Seasonal_Mode` is `Winter`. |
| + | - [ ] Verify in Occupied Mode that the electric baseboard remains OFF when `Seasonal_Mode` is `Summer`. |
| + | - [ ] With CO2 injection, verify that the VAV minimum flow position increases as CO2 levels rise from 0 ppm differential to 1,000 ppm. |
| + | - [ ] Verify the "Static Pressure Reset Alarm" can be generated. |

| + | |
| + | 2. **Determine contact state:** |
| + | - **NO (Normally Open):** Open when off, closes when on |
| + | * Use for: Proof of operation (pump running = closed contact) |
| + | - **NC (Normally Closed):** Closed when off, opens when on |
| + | * Use for: Alarm monitoring (fire alarm = opens when tripped) |
| + | |
| + | 3. **Connect to controller binary input:** |
| + | - **2-wire connection (most common):** |
| + | * Wire 1: From contact terminal 1 → Controller BI terminal |
| + | * Wire 2: From contact terminal 2 → Controller common |
| + | - **Polarity doesn't matter** for dry contacts |
| + | - Tighten terminals: 7-9 in-lbs |
| + | - Route wiring away from high-voltage cables |
| + | |
| + | 4. **Configure controller input:** |
| + | - Set as NO (normal state = open) or NC (normal state = closed) |
| + | - Example: Motor status NO contact: |
| + | * Motor OFF: Contact open = Binary input FALSE/0 |
| + | * Motor ON: Contact closed = Binary input TRUE/1 |
| + | |
| + | 5. **Label wiring:** |

| + | |
| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### BINARY INPUT ALWAYS FALSE (Never TRUE) |
| + | 1. **Check equipment:** Is device actually running? |
| + | 2. **Test contact:** Measure continuity across contact |
| + | - **If open when should be closed:** Contact not closing - device issue |
| + | 3. **Check wiring:** Verify connections at both ends |
| + | 4. **Test continuity end-to-end:** Should be <5 ohms when closed |
| + | 5. **Verify controller config:** Input set to correct contact type (NO vs NC)? |
| + | 6. **If wiring OK but no response:** Controller input may be failed |
| + | |
| + | ### BINARY INPUT ALWAYS TRUE (Never FALSE) |
| + | 1. **Check equipment:** Is device actually off? |
| + | 2. **Test contact:** Should be open when equipment off |
| + | - **If closed when should be open:** Contact stuck - device issue |
| + | 3. **Check for short circuit:** Wires touching somewhere |
| + | 4. **Verify controller config:** May be configured backwards (NO vs NC) |
| + | 5. **If persistently closed:** Contact welded shut or wiring short |
| + | |
| + | ### BINARY INPUT ERRATIC / CHATTERING |
| + | 1. **Mechanical chatter:** Contact bouncing during switching |
| + | - Solution: Add time delay in controller (0.5-1 sec) |
| + | 2. **Loose wiring:** Check all connections tight |
| + | 3. **EMI/RFI interference:** Route wiring away from power cables |
| + | 4. **Contact arcing:** Contact switching too much current - add relay |
| + | 5. **Vibration:** Secure device and wiring to prevent movement |
| + | |
| + | ### BINARY INPUT REVERSED (Shows opposite of actual) |
| + | 1. **Controller config:** Input configured as NO when should be NC (or vice versa) |
| + | 2. **Solution:** Change controller configuration to opposite type |
| + | 3. **Verify logic:** Some controllers use "Active High" or "Active Low" |
| + | |
| + | ### ALARM NOT TRIGGERING |
| + | 1. **Verify binary input changing state:** Check controller display |
| + | 2. **Check alarm configuration:** |
| + | - Alarm enabled? |
| + | - Correct trigger condition (state change vs specific state)? |
| + | - Time delay too long? |
| + | 3. **Check notification routing:** Email, text, or on-screen only? |
| + | |
| + | ### VOLTAGE SENSING NOT WORKING |
| + | 1. **Check voltage present:** Measure with multimeter at monitored circuit |
| + | 2. **Verify voltage sensing module powered:** Some require separate power |
| + | 3. **Check voltage rating:** Module rated for monitored voltage? |
| + | 4. **Test module output contacts:** Should close when voltage present |
| + | 5. **If voltage present but module no output:** Module failed - replace |

| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **NO vs NC confusion:** Most common wiring error - verify contact type before wiring |
| + | ✓ **Fail-safe design:** Use NC contacts for critical alarms (wire break = alarm) |
| + | ✓ **Fire alarm interface:** Always NC contact - must fail to alarm condition |
| + | ✓ **Controller configuration:** MUST match actual contact type (NO vs NC) |
| + | ✓ **Contact ratings:** Don't exceed contact amp/voltage rating |
| + | ✓ **Time delays:** Add 0.5-1 sec delay to prevent contact bounce false alarms |
| + | ✓ **Wire routing:** Keep binary input wiring away from high-voltage to prevent interference |
| + | ✓ **Voltage sensing:** Use when no dry contacts available (direct voltage monitoring) |
| + | ✓ **Status feedback:** Always verify equipment actually operating (BI shows contact state, not mechanical operation) |
| + | ✓ **Alarm logic:** "Alarm on change" vs "Alarm on state" - choose correct |
| + | ✓ **Multiple contacts:** Can wire multiple NO contacts in series for "ALL ON" logic |
| + | ✓ **Multiple contacts:** Can wire multiple NC contacts in parallel for "ANY ALARM" logic |

| + | |
| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### NO READING / SENSOR FAULT |
| + | 1. Verify supply voltage at sensor: 24VAC/VDC ±10% |
| + | 2. Wait 30 minutes for warm-up period |
| + | 3. Check all wiring connections tight |
| + | 4. Test continuity end-to-end: <5 ohms |
| + | 5. Measure output signal: Should be 2-10V or 4-20mA (not 0V or 0mA) |
| + | 6. **If 0V or 0mA:** Sensor failed - replace |
| + | 7. **If voltage present but no reading:** Check controller input config |
| + | |
| + | ### READING STUCK / NOT CHANGING |
| + | 1. Verify sensor has power (LED indicator if equipped) |
| + | 2. Wait for warm-up period (30 min) |
| + | 3. Perform breath test - should increase reading |
| + | 4. Check sensor lens/opening not obstructed or dirty |
| + | 5. **If still stuck:** Replace sensor (NDIR element failed) |
| + | |
| + | ### READING TOO HIGH (Always >1000 PPM) |
| + | 1. Check sensor location: |
| + | - Near kitchen or break room? |
| + | - In dead air space with poor circulation? |
| + | - Too close to occupants? |
| + | 2. Verify outdoor air ventilation operating correctly |
| + | 3. Compare to portable CO2 meter (calibrated reference) |
| + | 4. **If consistently high by same offset:** Calibrate sensor |
| + | 5. **If true high reading:** Increase ventilation rate |
| + | |
| + | ### READING TOO LOW (Always <400 PPM) |
| + | 1. Check sensor location - too close to OA intake or supply diffuser? |
| + | 2. Verify sensor not in high-velocity airstream |
| + | 3. Compare to portable CO2 meter |
| + | 4. **If sensor reads low:** Calibrate or replace |
| + | 5. **Note:** Reading below 400 PPM indoors is usually sensor error |
| + | |
| + | ### ERRATIC / FLUCTUATING READINGS |
| + | 1. Check for air currents affecting sensor (supply diffuser too close) |
| + | 2. Verify sensor mounted securely (not vibrating) |
| + | 3. Check wiring for EMI/RFI interference |
| + | 4. Look for moisture in sensor or connections |
| + | 5. **If persists:** Replace sensor |
| + | |
| + | ### SLOW RESPONSE |
| + | 1. Normal: CO2 sensors respond slower than temperature (1-2 min typical) |
| + | 2. Check sensor sampling rate (some have adjustable averaging) |
| + | 3. Verify sensor not obstructed |
| + | 4. **If >5 minutes to respond:** Sensor may be failing - replace |

| + | ## CALIBRATION |
| + | |
| + | **When Needed:** |
| + | - Annual calibration recommended (NDIR sensors drift over time) |
| + | - After sensor replacement |
| + | - If reading consistently off by >100 PPM |
| + | |
| + | **Methods:** |
| + | |
| + | **OPTION A: Fresh Air Calibration (Simple)** |
| + | 1. Expose sensor to outdoor air for 20+ minutes |
| + | 2. Outdoor air should read 400-450 PPM |
| + | 3. Adjust sensor calibration to 400 PPM (if adjustable) |
| + | 4. **Note:** Only accurate if outdoor air is actually ~400 PPM |
| + | |
| + | **OPTION B: Zero Gas Calibration (Accurate)** |
| + | 1. Requires calibration gas (400 PPM CO2 in nitrogen) |
| + | 2. Apply calibration gas to sensor per manufacturer procedure |
| + | 3. Adjust sensor to match calibration gas concentration |
| + | 4. **Preferred method** - most accurate |
| + | |
| + | **OPTION C: Controller Offset (Temporary)** |
| + | 1. If sensor consistently off by fixed amount (e.g., always reads 100 PPM high) |
| + | 2. Apply offset in controller configuration |
| + | 3. **Not a permanent fix** - sensor should be recalibrated or replaced |
| + | |
| + | **Acceptable Tolerance:** ±50 PPM |
| + | |
| + | **Document:** Tech name, date, calibration method, before/after readings |
| + | |
| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Mount height:** 4-6 feet (breathing zone) - CO2 heavier than air but well-mixed indoors |
| + | ✓ **Warm-up time:** Always allow 30 min minimum after power-up before commissioning |
| + | ✓ **Location critical:** Representative location essential - avoid OA intakes and supply diffusers |
| + | ✓ **NDIR technology:** Most accurate but requires annual calibration |
| + | ✓ **Range selection:** 0-2000 PPM for most spaces, 0-5000 PPM for high-occupancy (auditoriums, gyms) |
| + | ✓ **DCV savings:** Typically 10-30% energy savings vs fixed ventilation rate |
| + | ✓ **ASHRAE 62.1:** Requires CO2 sensors for DCV in densely occupied spaces |
| + | ✓ **Breath test:** Quick field verification - exhaled breath ~40,000 PPM CO2 |
| + | ✓ **Outdoor air:** ~400-450 PPM baseline (slowly increasing globally ~2 PPM/year) |
| + | ✓ **False high readings:** Check for nearby combustion sources, kitchens, smoking |
| + | ✓ **Multi-zone systems:** One sensor per zone typical, or duct-mounted in return air |

| + | |
| + | ### READING TOO LOW |
| + | 1. Verify CT range adequate (not oversized) |
| + | - Example: 10A load with 0-500A CT gives low resolution |
| + | 2. Check CT fully closed (gap causes low reading) |
| + | 3. Verify conductor centered in CT opening |
| + | 4. Compare to clamp meter reading |
| + | 5. Check for loose CT output wiring |
| + | 6. **If consistently low by same %:** CT may need calibration |
| + | |
| + | ### READING TOO HIGH |
| + | 1. Verify CT range matches spec (not undersized) |
| + | 2. Check CT arrow direction (reversed gives false reading) |
| + | 3. Verify only ONE conductor through CT |
| + | - **Common error:** Both hot and neutral = double reading |
| + | 4. Compare to clamp meter |
| + | 5. **If consistently high:** CT may be wrong ratio or failing |
| + | |
| + | ### ERRATIC / FLUCTUATING READING |
| + | 1. Check CT securely mounted (vibration can cause fluctuation) |
| + | 2. Verify CT fully closed and latched |
| + | 3. Check output wiring for loose connections |
| + | 4. Look for EMI/RFI interference (route wiring away from power cables) |
| + | 5. Verify good connection at controller input |
| + | 6. **If motor has VFD:** Some fluctuation normal (PWM switching) |
| + | |
| + | ### READING NEGATIVE |
| + | 1. **CT arrow reversed** - pointing toward source instead of load |
| + | 2. Open CT (if can be done safely) and reinstall with arrow toward load |
| + | 3. **Or:** Some controllers allow signal reversal in software |
| + | |
| + | ### HIGH INRUSH SPIKE CAUSES NUISANCE ALARMS |
| + | 1. Normal motor startup is 5-8× FLA for 1-2 seconds |
| + | 2. Adjust controller alarm time delay (3-5 seconds typical) |
| + | 3. Or set alarm threshold higher (125% FLA instead of 110%) |
| + | |
| + | ### CT WON'T CLOSE / GAP VISIBLE |
| + | 1. Conductor too large for CT opening - need larger CT |
| + | 2. Multiple conductors trying to fit through CT |
| + | 3. CT hinge damaged - replace CT |
| + | 4. Verify CT rated for conductor size |

| + | |
| + | ## CALIBRATION |
| + | |
| + | **When Needed:** |
| + | - Rarely required - CTs are typically factory calibrated |
| + | - If reading consistently off by >5% |
| + | - After CT replacement |
| + | |
| + | **Verification Procedure:** |
| + | 1. Measure actual current with calibrated clamp meter |
| + | 2. Record CT output from controller |
| + | 3. Calculate expected output: (Actual Current / CT Range) × Output Range |
| + | 4. Compare actual to expected |
| + | 5. **If within ±5%:** No calibration needed |
| + | 6. **If outside ±5%:** Apply controller offset or replace CT |
| + | |
| + | **Controller Offset (if available):** |
| + | - Most controllers allow calibration offset |
| + | - Calculate correction factor |
| + | - Apply in controller configuration |
| + | - Retest with clamp meter |
| + | |
| + | **Example:** |
| + | - CT Range: 0-50A, Output: 0-10V |
| + | - Clamp meter: 25A actual |
| + | - Expected output: (25/50) × 10V = 5.0V |
| + | - CT reads: 4.5V |
| + | - Error: -0.5V (-10%) |
| + | - Apply +0.5V offset in controller |
| + | |
| + | **Acceptable Tolerance:** ±5% of reading |
| + | |
| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **CT sizing:** Select range for 150% of maximum expected current (allows for motor startup) |
| + | ✓ **Arrow direction:** MUST point toward load (away from breaker) - reversed gives false readings |
| + | ✓ **One conductor only:** Common error is running supply AND return through CT = 0 reading |
| + | ✓ **Not on neutral:** Always install on hot leg, never neutral (neutral current should equal hot) |
| + | ✓ **Three-phase motors:** Need three CTs for full monitoring (one per phase) |
| + | ✓ **Single-phase motors:** One CT on hot leg sufficient |
| + | ✓ **VFD applications:** CT must be rated for PWM waveforms (most modern CTs are) |
| + | ✓ **Proof of operation:** Set alarm at 20-30% FLA (below normal running current) |
| + | ✓ **Energy monitoring:** Sum all three phases for total power calculation (requires kW transducer) |
| + | ✓ **Split-core advantage:** Can install without de-energizing (but only if qualified) |
| + | ✓ **Solid-core CTs:** More accurate but require conductor disconnection for install |
| + | ✓ **Startup inrush:** Normal 5-8× FLA spike for 1-2 seconds - don't set alarms too sensitive |
| + | |
| + | ### Typical FLA by Motor HP (460V, 3-phase) |
| + | *Note: These are typical values and can vary based on motor efficiency, manufacturer, and specific load conditions.* |
| + | - 1 HP: 1.1A |
| + | - 2 HP: 2.2A |
| + | - 3 HP: 3.3A |
| + | - 5 HP: 5.5A |
| + | - 7.5 HP: 9A |
| + | - 10 HP: 11A |
| + | - 15 HP: 17A |
| + | - 20 HP: 22A |
| + | - 25 HP: 27A |
| + | - 30 HP: 32A |
| + | - 40 HP: 43A |
| + | - 50 HP: 54A |

| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### NO POWER / ACTUATOR DEAD |
| + | 1. Measure supply voltage at actuator terminals: 24VAC/VDC ±10% |
| + | - **If no voltage:** Check controller output, circuit breaker, wiring |
| + | 2. Test continuity of power wiring end-to-end: <5 ohms |
| + | 3. Check terminal connections tight |
| + | 4. Verify polarity (DC circuits) |
| + | 5. Listen for motor sound when power applied (should hear humming) |
| + | 6. **If voltage present but no sound:** Replace actuator (motor failed) |
| + | |
| + | ### ACTUATOR RUNS BUT DAMPER DOESN'T MOVE |
| + | 1. **Check coupling:** Tighten set screws (may have loosened) |
| + | 2. **Manually rotate actuator:** Should feel resistance (motor engaged) |
| + | 3. **Check damper shaft:** May be disconnected from blades inside duct |
| + | 4. **Check linkage:** Rods or arms may be disconnected or broken |
| + | 5. **If coupling slipping:** Reposition and tighten, may need new coupling |
| + | 6. **If shaft broken:** Requires damper disassembly/replacement |
| + | |
| + | ### ACTUATOR MOVES BUT INCORRECT POSITION |
| + | 1. Verify control signal at actuator terminals: |
| + | - 0V/2V/4mA = Closed |
| + | - 10V/10V/20mA = Open |
| + | - **If signal correct but position wrong:** Check mechanical stops |
| + | 2. Adjust mechanical stops to match damper travel |
| + | 3. Verify coupling aligned correctly (0° = closed, 90° = open) |
| + | 4. Check position feedback wiring (if equipped) |
| + | 5. **If position feedback wrong:** Verify feedback wire connected, check at controller |
| + | 6. **If mechanical stops maxed out:** May need larger torque actuator |
| + | |
| + | ### ACTUATOR STALLS OR BINDS |
| + | 1. Check damper blades for physical obstruction |
| + | 2. Verify linkage not bent or binding |
| + | 3. Check shaft bushings not seized |
| + | 4. Measure current draw: >300mA indicates overload |
| + | 5. **If overcurrent:** Damper too large for actuator torque rating |
| + | 6. **If binding at certain position:** Adjust linkage or repair damper |
| + | 7. **If generally binding:** Lubricate shaft bushings, check alignment |
| + | |
| + | ### SLOW OR ERRATIC MOVEMENT |
| + | 1. Measure supply voltage under load: Should stay within ±10% |
| + | 2. Check for voltage drop in long wire runs |
| + | 3. Verify control signal stable (not fluctuating) |
| + | 4. Listen for unusual motor sounds (grinding, clicking) |
| + | 5. Check gearbox for wear or damage |
| + | 6. **If voltage drops:** Increase wire gauge or add local power supply |
| + | 7. **If motor sounds bad:** Replace actuator (gearbox failing) |
| + | |
| + | ### ACTUATOR WON'T RETURN TO FAIL-SAFE (SR models) |
| + | 1. Remove power and manually feel spring tension |
| + | 2. **If no spring tension:** Spring broken - replace actuator |
| + | 3. **If spring weak:** May be old actuator, replace |
| + | 4. Check for mechanical binding preventing spring return |
| + | 5. Verify damper not too large for spring force |
| + | |
| + | ### POSITION FEEDBACK INCORRECT |
| + | 1. Verify feedback wire connected properly |
| + | 2. Measure feedback signal at actuator: Should match position (0-10V or 2-10V) |
| + | 3. Measure feedback signal at controller: Should match actuator reading |
| + | 4. **If different at controller:** Wiring issue, check for shorts or high resistance |
| + | 5. **If same but wrong:** Feedback potentiometer may be misaligned |
| + | 6. **If no feedback signal:** Replace actuator (feedback pot failed) |

| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Coupling slipping:** Use Loctite on set screws, tighten to spec (don't overtighten) |
| + | ✓ **Actuator too small:** Check damper size vs torque rating (35 in-lbs per ft² of damper area) |
| + | ✓ **Spring return vs non-spring:** SR for fail-safe applications (OA dampers close on power loss) |
| + | ✓ **2-10V vs 0-10V:** 2-10V provides feedback if wire breaks (will read 0V = alarm) |
| + | ✓ **Mechanical stops:** Set stops to match damper travel (prevents over-rotation) |
| + | ✓ **Outdoor applications:** Use NEMA 4 rated actuator, apply thread sealant |
| + | ✓ **Linkage alignment:** Ensure damper blades parallel to each other through full stroke |
| + | ✓ **Feedback wiring:** If 4-wire, feedback goes to AI input on controller (separate from command AO) |
| + | ✓ **Stroke time adjustment:** Some models have adjustable stroke time (check manual) |
| + | ✓ **Cold weather:** Actuators may be slower in extreme cold (-40°F), allow extra time |

| + | - Teflon tape or pipe thread sealant |
| + | - Isolation valves (if not present) |
| + | - Wire (18AWG) |
| + | - Wire nuts or terminal blocks |
| + | - Ball valve or drain (for testing) |
| + | |
| + | ### PRE-INSTALL |
| + | - [ ] Verify flow switch rated for: |
| + | * Pipe size (must match) |
| + | * Flow range (gpm expected) |
| + | * Liquid type (water, glycol, oil) |
| + | * Temperature range |
| + | * Pressure rating |
| + | - [ ] Identify installation location: |
| + | * Straight pipe section (10× pipe diameter from elbows/valves) |
| + | * Accessible for service |
| + | * After pump (in flow direction) |
| + | - [ ] Verify isolation valves present or plan to install |
| + | |
| + | ### INSTALL STEPS - PADDLE TYPE (Most Common) |
| + | |
| + | **STEP 1: System Isolation** |
| + | 1. **Notify building operator** |
| + | 2. **Close isolation valves** upstream and downstream |
| + | 3. **Open drain valve** to depressurize section |
| + | 4. **Verify 0 PSI** with pressure gauge |
| + | 5. **Place bucket** under work area |
| + | |
| + | **STEP 2: Prepare Pipe** |
| + | |
| + | **OPTION A: Existing Tee/Boss (Preferred)** |
| + | - Use existing threaded opening in pipe |
| + | - Clean threads and apply Teflon tape |
| + | |
| + | **OPTION B: Install New Tee (Requires Pipe Modification)** |
| + | 1. **Cut pipe** at selected location |
| + | 2. **Install Tee fitting** with unions for future service |
| + | 3. **Ensure Tee points in flow direction** (arrow on switch) |
| + | 4. **Pressure test** before proceeding |
| + | |
| + | **OPTION C: Hot Tap (Specialized, Requires Contractor)** |
| + | - Specialized procedure for drilling a hole in a live, pressurized pipe (requires highly specialized equipment and training) |
| + | - Typically requires mechanical contractor with hot tapping expertise |
| + | - Used when system cannot be drained or taken offline |
| + | - **CRITICAL SAFETY:** Only qualified, experienced personnel with proper safety protocols should perform hot tapping. |
| + | |
| + | **STEP 3: Install Flow Switch** |
| + | 1. **Apply Teflon tape** to switch threads (3-4 wraps, clockwise) |
| + | - Or use pipe dope per manufacturer |
| + | 2. **Thread switch into Tee** or boss |
| + | 3. **Orient switch:** |
| + | - Arrow on switch points in flow direction (critical) |
| + | - Electrical connection accessible for wiring |
| + | - Paddle perpendicular to flow (not parallel) |
| + | 4. **Tighten switch:** |
| + | - Hand tight, then 1-2 turns with wrench |
| + | - **Do not overtighten** - can crack housing |
| + | 5. **Verify paddle moves freely:** |
| + | - Gently push paddle (if accessible) |
| + | - Should return to rest position |
| + | |
| + | **STEP 4: Set Flow Setpoint** |
| + | - **Adjustable models:** |
| + | * Rotate adjustment dial to desired flow rate (gpm or ft/sec) |
| + | * Typical setting: 1-2 ft/sec for proof of flow |
| + | * Consult pump curve for expected flow |
| + | - **Fixed models:** |
| + | * Verify setpoint adequate for application |
| + | * Typically 0.5-1.0 ft/sec factory set |
| + | |
| + | **STEP 5: Wire Flow Switch** |
| + | 1. **Locate terminal compartment** on switch |
| + | 2. **Remove cover** (may require screwdriver) |
| + | 3. **Identify terminals:** |
| + | - COM (Common) |
| + | - NO (Normally Open) - Closes when flow present |
| + | - NC (Normally Closed) - Opens when flow present |
| + | 4. **Connect to controller:** |
| + | - Use NO contact for proof of flow: |
| + | * NO → Controller BI |
| + | * COM → Controller COM |
| + | - Flow present = Contact closed = TRUE/1 |
| + | - No flow = Contact open = FALSE/0 |
| + | 5. **Tighten terminal screws:** 7-9 in-lbs |
| + | 6. **Route wiring** away from hot pipes |
| + | 7. **Reinstall terminal cover** (weatherproof seal) |
| + | |
| + | **STEP 6: Pressure Test and Restore** |
| + | 1. **Close all drain valves** |
| + | 2. **Slowly open isolation valves:** |
| + | - Open upstream valve 1/4 turn, check for leaks |
| + | - If no leaks, fully open upstream valve |
| + | - Repeat for downstream valve |
| + | 3. **Check for leaks** at switch installation |
| + | - Tighten if minor seepage (1/4 turn max) |
| + | - If significant leak: Close valves, remove switch, reapply sealant |
| + | 4. **Verify system pressure** normal (30-150 PSI typical) |
| + | 5. **Start pump** (coordinate with operator) |
| + | |
| + | **STEP 7: Label** |
| + | - Example: "PUMP-1-FLOW" or "CHW-FLOW" |
| + | - Label at both switch and controller |
| + | |
| + | ### POST-INSTALL |

| + | - **Contact State:** Open (NO) or Closed (NC) |
| + | - **Controller Reading:** FALSE/0 (using NO contact) |
| + | - **Paddle Position:** At rest (spring returns paddle) |
| + | |

| + | - **Minimum Flow Alarm:** 1.5-3.0 ft/sec (detects low flow condition) |
| + | - **Target Flow:** 3-8 ft/sec typical for HVAC (consult pump curve) |
| + | |
| + | --- |
| + | |
| + | ## PROOF OUT TESTS |
| + | |

| + | - **Expect:** |
| + | * Contact open (NO) = FALSE |
| + | * Controller shows "No Flow" |
| + | - **Pass If:** Switch correctly shows no flow |
| + | |
| + | ### TEST 2: Flow Established Test |

| + | * Contact closes (NO) within 2-5 seconds |
| + | * Controller changes to "Flow" or TRUE/1 |
| + | * Pump current increases (verify with clamp meter) |
| + | - **Pass If:** Switch detects flow when pump starts |
| + | |
| + | ### TEST 3: Flow Stoppage Test |
| + | - **Do:** Close downstream valve (simulate flow stoppage) |
| + | - **WARNING:** Don't leave valve closed long (pump deadhead) |
| + | - **Expect:** |
| + | * Contact opens (NO) = FALSE after 2-5 seconds |
| + | * Controller shows "No Flow" alarm |

| + | - [ ] No communication errors |
| + | |
| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### FLOW SWITCH NEVER SHOWS FLOW (Always FALSE) |
| + | 1. **Verify pump is running:** |
| + | - Check pump current with clamp meter |
| + | - Hear pump motor running |
| + | - **If pump not running:** Pump problem, not switch |
| + | 2. **Check for actual flow:** |
| + | - Feel pipe vibration (flow present) |
| + | - Check pressure gauges (ΔP indicates flow) |
| + | - **If no flow with pump running:** Closed valve, air lock, or pump issue |
| + | 3. **Check flow switch orientation:** |
| + | - Arrow must point in flow direction |
| + | - **If reversed:** Flow pushes paddle closed (wrong way) |
| + | 4. **Check setpoint:** |
| + | - May be set too high for actual flow |
| + | - Reduce setpoint and retest |
| + | 5. **Check paddle:** |
| + | - Paddle may be stuck or broken |
| + | - Remove switch (isolate system first), inspect paddle |
| + | 6. **Test contact:** |
| + | - Manually push paddle, measure contact continuity |
| + | - **If no continuity when paddle pushed:** Switch failed |
| + | |
| + | ### FLOW SWITCH ALWAYS SHOWS FLOW (Always TRUE) |
| + | 1. **Check for actual flow:** |
| + | - Pump may be running (expected) |
| + | - **If pump off but shows flow:** False reading |
| + | 2. **Check wiring:** |
| + | - NC contact may be wired instead of NO |
| + | - Wires may be crossed or shorted |
| + | 3. **Test contact:** |
| + | - Disconnect wiring, measure contact with no flow |
| + | - **If contact closed with no flow:** Switch failed or stuck |
| + | |
| + | ### ERRATIC FLOW INDICATION (Cycling TRUE/FALSE) |
| + | 1. **Air in system:** |
| + | - Air pockets cause intermittent paddle deflection |
| + | - Vent system to remove air |
| + | 2. **Turbulent flow:** |
| + | - Switch too close to elbow, valve, or pump |
| + | - Relocate to straight section (10× pipe diameter) |
| + | 3. **Vibration:** |
| + | - Pipe vibration causing paddle to flutter |
| + | - Secure piping to reduce vibration |
| + | - Increase switch time delay (if adjustable) |
| + | 4. **Flow oscillation:** |
| + | - Pump cycling or VFD hunting |
| + | - Check pump and control system |
| + | |
| + | ### LEAKING AT FLOW SWITCH |
| + | 1. **Minor seepage:** |
| + | - Tighten switch 1/4 turn |
| + | - **Do not overtighten** (can crack housing) |
| + | 2. **Persistent leak:** |
| + | - Remove switch, inspect threads |
| + | - Reapply Teflon tape (3-4 wraps) or pipe dope |
| + | - Inspect O-ring or gasket (replace if damaged) |
| + | - Reinstall and pressure test |
| + | 3. **Crack in housing:** |
| + | - Replace switch (overtightened or defective) |
| + | |
| + | ### DELAYED RESPONSE (Slow to Show Flow) |
| + | 1. **Normal delay:** 2-5 seconds typical for paddle to deflect |
| + | 2. **Check setpoint:** May be set too high, paddle struggles to reach |
| + | 3. **Check paddle:** May be corroded or sticky |
| + | - Remove and clean (isolate system first) |
| + | 4. **Reduce setpoint:** If flow low, lower setpoint to 0.5 ft/sec |
| + | |
| + | ### FALSE FLOW INDICATION (Shows Flow with No Pump) |
| + | 1. **Gravity flow:** |
| + | - System on multiple levels, gravity flow possible |
| + | - Install check valve to prevent reverse flow |
| + | 2. **Paddle stuck:** |
| + | - Debris or corrosion holding paddle deflected |
| + | - Remove switch, clean paddle, reinstall |
| + | 3. **Contact stuck closed:** |
| + | - Switch failed, replace |
| + | |

| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Arrow direction CRITICAL:** Must point in flow direction or won't work |
| + | ✓ **Straight pipe required:** Install 10× pipe diameter from elbows, valves, pumps |
| + | ✓ **Setpoint selection:** 0.5-1.5 ft/sec for proof of flow, higher for minimum flow alarm |
| + | ✓ **Pipe size matters:** Must match pipe size or flow velocity calculation wrong |
| + | ✓ **Air in system:** Most common cause of erratic behavior - vent system |
| + | ✓ **Teflon tape application:** 3-4 wraps clockwise, don't overtighten switch |
| + | ✓ **No flow with pump running:** Check for closed valves, air lock, pump cavitation |
| + | ✓ **Proof of operation:** Use in interlock: "Alarm if pump ON but no flow >60 seconds" |
| + | ✓ **Freeze protection:** "Alarm if temperature <40°F AND no flow" |
| + | ✓ **Low flow alarm:** Set higher setpoint (3-5 ft/sec) to detect loss of flow |
| + | ✓ **Pressure vs flow:** Pressure can be normal with no flow (closed valve) - flow switch needed |
| + | ✓ **Time delay:** Add 30-60 second delay in controller to prevent nuisance alarms at startup |
| + | |
| + | ### Typical Flow Velocities (HVAC Systems) |
| + | - **Chilled Water:** 4-8 ft/sec |
| + | - **Hot Water:** 2-6 ft/sec |
| + | - **Condenser Water:** 5-10 ft/sec |
| + | - **Glycol (20%):** 3-6 ft/sec |
| + | - **Proof of Flow Setting:** 0.5-1.5 ft/sec (20-30% of target) |

| + | ### READING TOO HIGH (Always >70% RH indoors) |
| + | 1. Check sensor location - near moisture source? |
| + | 2. Verify building HVAC dehumidification operating |
| + | 3. Compare to portable humidity meter |
| + | 4. Check for water damage or leaks in area |
| + | 5. **If sensor consistently high:** May need recalibration or replacement |
| + | |
| + | ### READING TOO LOW (Always <20% RH indoors) |
| + | 1. Check sensor location - near supply diffuser? |
| + | 2. Verify building humidification operating (winter) |
| + | 3. Compare to portable humidity meter |
| + | 4. **If sensor consistently low:** Recalibrate or replace |
| + | |

| + | ## CALIBRATION |
| + | |
| + | **When Needed:** |
| + | - Annual calibration recommended |
| + | - If reading consistently off by >5% RH |
| + | - After sensor replacement |
| + | |
| + | **Methods:** |
| + | |
| + | **OPTION A: Salt Test (Simple, Low Accuracy)** |
| + | 1. Requires: Table salt, small container, sealed bag |
| + | 2. Mix saturated salt solution (pile of salt in water) |
| + | 3. Place sensor and salt solution in sealed bag |
| + | 4. Wait 8-12 hours for stabilization |
| + | 5. Should read 75% RH at room temperature |
| + | 6. Adjust if reading significantly different |
| + | 7. **Note:** Only accurate to ±5% RH |
| + | |
| + | **OPTION B: Calibrated Humidity Chamber (Accurate)** |
| + | 1. Requires: Humidity calibration chamber or standard |
| + | 2. Place sensor in chamber with known humidity |
| + | 3. Wait for stabilization (1-2 hours) |
| + | 4. Adjust sensor to match chamber humidity |
| + | 5. Test at multiple points (33%, 75% RH typical) |
| + | 6. **Preferred method** - most accurate |
| + | |
| + | **OPTION C: Reference Meter Comparison** |
| + | 1. Place calibrated portable meter next to sensor |
| + | 2. Wait 10-15 minutes for both to stabilize |
| + | 3. Compare readings |
| + | 4. **If consistently offset:** Apply controller offset or recalibrate sensor |
| + | |
| + | **OPTION D: Controller Offset (Temporary)** |
| + | 1. If sensor consistently off by fixed amount |
| + | 2. Apply offset in controller configuration |
| + | 3. **Not permanent fix** - sensor should be recalibrated |
| + | |
| + | **Acceptable Tolerance:** ±3% RH for most BAS applications |
| + | |
| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Mount height:** 4-6 feet typical - humidity generally well-mixed in conditioned spaces |
| + | ✓ **Warm-up time:** Allow 5 min after power-up before commissioning |
| + | ✓ **Location critical:** Away from moisture sources (humidifiers, sinks, showers) unless monitoring those |
| + | ✓ **Temperature affects humidity:** Warm air holds more moisture - expect changes with temp |
| + | ✓ **Relative humidity:** % of moisture air can hold at current temperature (not absolute moisture) |
| + | ✓ **Condensation risk:** Occurs when surfaces below dew point (typically >70% RH) |
| + | ✓ **Winter heating:** Tends to dry indoor air (20-40% RH common) |
| + | ✓ **Summer cooling:** AC removes moisture (40-60% RH typical) |
| + | ✓ **Combo sensors:** Many include temperature - verify both signals work correctly |
| + | ✓ **Breath test:** Quick verification - exhaled breath ~90-95% RH |
| + | ✓ **Calibration drift:** Humidity sensors drift more than temp sensors - annual cal recommended |
| + | ✓ **Contamination:** Dust, chemicals, smoke can affect accuracy - clean or replace if contaminated |

| + | - Label maker |
| + | - Small flathead (for DIP switch adjustment) |
| + | |
| + | ### MATERIALS |
| + | - Occupancy sensor (correct type for application) |
| + | - Wire (18AWG for low-voltage, 14AWG for line-voltage) |
| + | - Wire nuts |
| + | - Ceiling/wall mounting hardware |
| + | - Labels |
| + | |
| + | ### PRE-INSTALL |
| + | - [ ] Select correct sensor type (PIR, ultrasonic, dual-tech) |
| + | - [ ] Verify coverage area adequate for space |
| + | - [ ] Confirm mounting height appropriate (8-12 ft typical for ceiling) |
| + | - [ ] Check power available (24V or 120V) |
| + | - [ ] Review wiring diagram for model |
| + | |
| + | ### INSTALL STEPS - CEILING MOUNT (Most Common) |
| + | |
| + | **STEP 1: Locate Mounting Position** |
| + | 1. **Coverage considerations:** |
| + | - Center of room preferred (360° PIR coverage) |
| + | - Avoid corners (dead zones behind sensor) |
| + | - Avoid direct line of sight to HVAC diffusers (air movement triggers ultrasonic) |
| + | - Avoid windows with direct sunlight (can trigger PIR) |
| + | - Height: 8-12 ft typical (follow manufacturer spec) |
| + | |
| + | 2. **Mounting location:** |
| + | - Ceiling: Use electrical box or sensor mounting bracket |
| + | - Wall: 6-8 ft height typical, aimed at expected occupant location |
| + | |
| + | **STEP 2: Install Sensor** |
| + | |
| + | **LOW-VOLTAGE (24VAC/VDC) - MOST COMMON FOR BAS:** |
| + | |
| + | 1. **Lock out power** if integrating with lighting circuit |
| + | 2. **Mount sensor to ceiling:** |
| + | - Attach to electrical box or bracket |
| + | - Route low-voltage control wire through ceiling to sensor |
| + | 3. **Connect wiring:** |
| + | - **Power (if required):** |
| + | * Red: +24VAC/VDC |
| + | * Black: Common |
| + | - **Relay Output to Controller:** |
| + | * Relay NO: To controller binary input |
| + | * Relay COM: To controller common |
| + | - **When occupied:** Relay closes = BI TRUE |
| + | - **When vacant:** Relay opens = BI FALSE |
| + | 4. **Tighten terminals:** 7-9 in-lbs |
| + | |
| + | **LINE-VOLTAGE (120VAC) - LIGHTING CONTROL:** |
| + | |
| + | 1. **LOCK OUT lighting circuit breaker** |
| + | 2. **Verify 0V with voltage tester** |
| + | 3. **Mount sensor** |
| + | 4. **Connect wiring:** |
| + | - Black (hot) from breaker → Sensor line input |
| + | - White (neutral) → Sensor neutral |
| + | - Red (switched hot) → Sensor load output → Lighting |
| + | - Green/bare (ground) → Sensor ground |
| + | 5. **For BAS integration:** |
| + | - Use sensor's low-voltage relay output (if available) |
| + | - Connect relay to controller binary input |
| + | |
| + | **STEP 3: Configure Sensor Settings** |
| + | |
| + | **DIP SWITCHES or ROTARY DIALS (varies by model):** |
| + | |
| + | 1. **Time Delay:** |
| + | - Lighting: 5-15 min typical |
| + | - HVAC: 15-30 min typical |
| + | - Set longer for areas with intermittent occupancy |
| + | |
| + | 2. **Sensitivity:** |
| + | - High: Detects small movements (office, classroom) |
| + | - Medium: Normal movements (conference room) |
| + | - Low: Large movements only (warehouse) |
| + | |
| + | 3. **Mode:** |
| + | - Auto On/Auto Off: Turns on when occupied, off when vacant |
| + | - Manual On/Auto Off: Must manually turn on, auto turns off |
| + | - Vacancy Mode: Manual on, auto off (energy code compliant in some areas) |
| + | |
| + | 4. **Photocell (if equipped):** |
| + | - Enable: Prevents operation if daylight adequate |
| + | - Disable: Operates regardless of light level |
| + | |
| + | 5. **Coverage Pattern (some models):** |
| + | - 360° for ceiling mount |
| + | - Sector coverage for wall mount |
| + | |
| + | **STEP 4: Label Wiring** |
| + | - Example: "RM-201-OCC" (Room 201 Occupancy) |
| + | - Label at both sensor and controller ends |
| + | |
| + | **STEP 5: Test and Adjust** |
| + | - See Proof Out Tests section |

| + | |
| + | --- |
| + | |
| + | ## EXPECTED READINGS |
| + | |
| + | ### INITIAL POWER-UP (Room Empty) |
| + | - **After time delay expires:** Relay open = FALSE/0 (vacant) |
| + | - **Sensor LED:** May blink when detecting motion (varies by model) |
| + | |
| + | ### OCCUPIED (Person in Room) |
| + | - **Relay Output:** Closed = TRUE/1 (occupied) |
| + | - **Controller Display:** Shows "Occupied" |
| + | - **Sensor LED:** May illuminate or blink (varies) |
| + | |
| + | ### VACANT (Person Leaves Room) |
| + | - **During time delay:** Relay stays closed (still occupied) |
| + | - **After time delay:** Relay opens = FALSE/0 (vacant) |
| + | - **Example:** 15-min delay means sensor shows vacant 15 min after last motion |
| + | |
| + | --- |
| + | |
| + | ## PROOF OUT TESTS |
| + | |
| + | ### TEST 1: Initial Detection Test |
| + | - **Do:** Walk into sensor coverage area |
| + | - **Expect:** |
| + | * Sensor LED blinks or illuminates (if equipped) |
| + | * Relay closes within 1-2 seconds |
| + | * Controller shows "Occupied" |
| + | - **Pass If:** Sensor detects occupancy immediately |
| + | |
| + | ### TEST 2: Coverage Area Test |
| + | - **Do:** Walk around room in grid pattern, all areas |
| + | - **Expect:** |
| + | * Sensor detects motion in all areas |
| + | * No "dead zones" where motion not detected |
| + | - **Pass If:** Full room coverage confirmed |
| + | - **If dead zones:** Adjust sensor aim or add additional sensor |
| + | |
| + | ### TEST 3: Time Delay Verification |
| + | - **Do:** |
| + | 1. Occupy room (trigger sensor) |
| + | 2. Leave room and stand outside |
| + | 3. Time how long until sensor shows vacant |
| + | - **Expect:** Sensor shows vacant after configured time delay |
| + | - **Pass If:** Time delay matches setting (±10%) |
| + | - **Example:** Set to 15 min, should trigger 14-16 min after last motion |
| + | |
| + | ### TEST 4: Sensitivity Test |
| + | - **Do:** Make small movements (typing, reading) in various locations |
| + | - **Expect:** |
| + | * High sensitivity: Detects small movements |
| + | * Medium sensitivity: Detects normal movements |
| + | * Low sensitivity: Detects only large movements |
| + | - **Pass If:** Sensitivity appropriate for space use |
| + | - **Adjust if:** False triggers (too sensitive) or misses occupancy (not sensitive enough) |
| + | |
| + | ### TEST 5: False Trigger Test |
| + | - **Do:** Room empty, observe sensor for 30 minutes |
| + | - **Expect:** No false triggers from: |
| + | * HVAC airflow |
| + | * Sunlight movement |
| + | * Reflections |
| + | * Nearby motion outside room |
| + | - **Pass If:** No false occupancy triggers |
| + | - **If false triggers:** Adjust sensitivity, reposition sensor, or cover windows |
| + | |

| + | |
| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### SENSOR NEVER SHOWS OCCUPIED |
| + | 1. **Check power:** Verify 24VAC or 120VAC present |
| + | 2. **Test sensor:** Walk directly under sensor, wave arms |
| + | - **If LED blinks but no relay:** Wiring issue |
| + | - **If no LED blink:** Sensor failed or power issue |
| + | 3. **Check wiring:** Verify relay output connected to controller BI |
| + | 4. **Test relay:** Measure continuity across relay contacts when occupied |
| + | - **If no continuity:** Sensor relay failed |
| + | 5. **Check controller config:** BI configured as NO contact? |
| + | |
| + | ### SENSOR ALWAYS SHOWS OCCUPIED |
| + | 1. **Check for false triggers:** |
| + | - HVAC airflow directly at sensor (ultrasonic) |
| + | - Sunlight through windows (PIR) |
| + | - Reflective surfaces (mirrors, shiny floors) |
| + | - Motion outside room (open doorway) |
| + | 2. **Reduce sensitivity:** Adjust to medium or low |
| + | 3. **Reposition sensor:** Away from triggers |
| + | 4. **Check wiring:** Short circuit causing relay to stay closed? |
| + | 5. **Check relay:** Relay contacts stuck closed - replace sensor |
| + | |
| + | ### SLOW TO DETECT OCCUPANCY |
| + | 1. **PIR sensors require motion:** |
| + | - Person must move to be detected |
| + | - Sitting still may not trigger sensor |
| + | - **Solution:** Use ultrasonic or dual-tech |
| + | 2. **Check sensitivity:** May be set too low |
| + | - Increase sensitivity setting |
| + | 3. **Check dead zones:** Person may be in coverage gap |
| + | - Reposition sensor or add additional sensor |
| + | |
| + | ### SENSOR DOESN'T STAY ON LONG ENOUGH |
| + | 1. **Increase time delay:** |
| + | - Lighting: Try 10-15 min |
| + | - HVAC: Try 20-30 min |
| + | 2. **Check sensor type:** |
| + | - PIR requires movement to reset timer |
| + | - Ultrasonic better for seated occupants |
| + | 3. **Consider dual-tech:** Maintains occupancy better |
| + | |
| + | ### SENSOR STAYS ON TOO LONG |
| + | 1. **Decrease time delay:** |
| + | - Set to minimum acceptable for application |
| + | 2. **Check for false triggers:** |
| + | - May be constantly re-triggering from HVAC, sunlight, etc. |
| + | |
| + | ### FALSE OCCUPANCY TRIGGERS |
| + | **PIR False Triggers:** |
| + | - Sunlight movement through windows → Add blinds or reposition |
| + | - Heat sources (space heaters, equipment) → Reposition sensor |
| + | - Air movement from diffusers → Adjust sensitivity |
| + | |
| + | **Ultrasonic False Triggers:** |
| + | - HVAC air turbulence → Reposition or reduce sensitivity |
| + | - Fans or moving equipment → Reduce sensitivity |
| + | - Sound/vibration → Isolate sensor from vibration source |
| + | |
| + | ### SENSOR MISSES OCCUPANCY (Not Detecting Present Person) |
| + | 1. **Check coverage area:** Person in dead zone? |
| + | 2. **Increase sensitivity:** May be set too low |
| + | 3. **Check sensor type:** |
| + | - PIR only detects movement (not presence) |
| + | - Person sitting still won't trigger PIR |
| + | - **Solution:** Use ultrasonic or dual-tech |
| + | 4. **Check sensor aim:** Wall-mount sensors must aim at occupied area |
| + | 5. **Check obstructions:** Furniture, partitions blocking view |
| + | |

| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Sensor selection:** PIR for large open areas, ultrasonic for restrooms/obstructed areas, dual-tech for best performance |
| + | ✓ **Mounting height:** 8-12 ft typical - too high reduces sensitivity, too low reduces coverage |
| + | ✓ **Time delay:** Longer for HVAC (20-30 min), shorter for lighting (5-15 min) |
| + | ✓ **PIR limitation:** Only detects movement, not presence - person sitting still won't maintain occupancy |
| + | ✓ **Ultrasonic advantage:** Detects small movements (typing, breathing) - better for seated occupants |
| + | ✓ **False triggers:** HVAC airflow (ultrasonic), sunlight (PIR), nearby motion (both) |
| + | ✓ **Dead zones:** Directly below ceiling mount sensor, behind obstructions |
| + | ✓ **Energy codes:** Some jurisdictions require vacancy mode (manual on) vs auto on |
| + | ✓ **Coverage overlap:** Multiple sensors can share same space, extend time delay |
| + | ✓ **Dual-tech operation:** BOTH technologies must trigger for occupancy (reduces false triggers) |
| + | ✓ **Daylight harvesting:** Use photocell to prevent operation during daylight (additional energy savings) |
| + | ✓ **Integration:** Use for HVAC setback, lighting control, security, demand control ventilation |
| + | |
| + | ### Typical Applications & Time Delays |
| + | - **Private Offices:** 15-20 min (intermittent occupancy) |
| + | - **Conference Rooms:** 20-30 min (presentations = minimal movement) |
| + | - **Classrooms:** 15-20 min (lecture = seated students) |
| + | - **Restrooms:** 5-10 min (short-term occupancy) |
| + | - **Break Rooms:** 10-15 min (variable use) |
| + | - **Warehouses:** 30 min (large space, intermittent activity) |
| + | - **Corridors:** 5-10 min (transient occupancy) |

| + | 5. Check duct probes not plugged with dirt/debris |
| + | 6. **If sensor has power but reads zero with system running:** Tubes may be reversed or blocked |
| + | |
| + | ### READING NEGATIVE (When Should Be Positive) |
| + | 1. **HIGH and LOW tubes reversed** - swap tubes at sensor |
| + | 2. Verify duct probe orientation (open end into airflow) |
| + | 3. Check that controller input not configured backwards |
| + | |
| + | ### READING TOO HIGH OR TOO LOW |
| + | 1. Verify sensor range matches application: |
| + | - Filter ΔP typically needs 0-1" W.C. or 0-2" W.C. range |
| + | - Duct static typically 0-1" W.C. range |
| + | - High static fans may need 0-2" or 0-5" W.C. range |
| + | 2. Check for kinked or restricted tubing |
| + | 3. Verify duct probe locations per design (not in turbulent area) |
| + | 4. Compare to handheld pressure meter (Magnehelic or digital) |
| + | 5. **If consistently offset:** Calibrate zero point |
| + | |
| + | ### ERRATIC / FLUCTUATING READING |
| + | 1. Check for water condensation in pressure tubing: |
| + | - Disconnect tubes and blow out water |
| + | - Improve tubing slope toward sensor |
| + | - Consider installing drip legs or water traps |
| + | 2. Verify duct probes in smooth, straight duct section (not near elbows, dampers) |
| + | 3. Check for air leaks in tubing connections |
| + | 4. Look for tubing vibration (fan vibration transmitted through tubes) |
| + | 5. **If persists:** Replace sensor (diaphragm may be damaged) |
| + | |
| + | ### SLOW RESPONSE |
| + | 1. Check pressure tubing length (>50 feet = slower response) |
| + | 2. Verify tubing not kinked or restricted |
| + | 3. Check tubing diameter adequate (1/4" OD typical) |
| + | 4. Look for water accumulation in tubes |
| + | 5. **Note:** Some slow response is normal for long tube runs (10-30 seconds) |
| + | |
| + | ### READING DRIFTS OVER TIME |
| + | 1. Temperature compensation issue - verify sensor in stable temp environment |
| + | 2. Check zero point calibration |
| + | 3. **If drifts significantly:** Replace sensor (diaphragm aging) |

| + | |
| + | **When Needed:** |
| + | - After installation (zero check) |
| + | - Annually or if reading drifts |
| + | - After sensor replacement |
| + | |
| + | **Zero Calibration:** |
| + | 1. Disconnect both pressure tubes from sensor (open to atmosphere) |

| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Tube orientation:** HIGH port to upstream probe, LOW port to downstream/reference |
| + | ✓ **Tube length:** Keep <50 feet for faster response, slope toward sensor |
| + | ✓ **Water in tubes:** Common problem - install drip legs or blow out regularly |
| + | ✓ **Probe location:** Straight duct section, avoid turbulent areas near elbows/dampers |
| + | ✓ **Probe orientation:** Open end facing into airflow (upstream) |
| + | ✓ **Filter ΔP alarms:** Typically set at 0.5-1.0" W.C. for filter change notification |
| + | ✓ **Static pressure control:** Used for VFD fan speed control, maintains constant pressure |
| + | ✓ **Building pressure:** Critical for healthcare, labs, clean rooms - requires tight tolerance sensors |
| + | ✓ **Negative readings:** Usually indicate reversed tubes or wrong probe orientation |
| + | ✓ **Range selection:** Match sensor range to application - oversized range reduces accuracy |
| + | ✓ **Magnehelic gauge:** Mechanical pressure gauge useful for field verification (no power required) |

| + | |
| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### RELAY DOESN'T CLICK / NO COIL VOLTAGE |
| + | 1. Measure voltage at controller output: Should be 24VAC when commanded ON |
| + | - **If no voltage at controller:** Controller output failed or not programmed |
| + | 2. Check coil wiring connections tight |
| + | 3. Test continuity of coil wiring end-to-end: <5 ohms |
| + | 4. Measure coil resistance: Should be 50-500 ohms |
| + | - **If infinity:** Coil burned out - replace relay |
| + | 5. **If voltage present but no click:** Replace relay (coil failed) |
| + | |
| + | ### RELAY CLICKS BUT LOAD DOESN'T RUN |
| + | 1. **Measure voltage across load terminals:** |
| + | - **If no voltage:** Contact wiring problem or power not on |
| + | 2. **Check contact side power:** |
| + | - Measure at breaker/disconnect: Should have line voltage |
| + | - **If no voltage:** Breaker tripped or power source issue |
| + | 3. **Check load wiring:** |
| + | - Verify load connected to correct relay terminals |
| + | - Check for loose connections |
| + | - Test continuity through contacts when energized: <1 ohm |
| + | 4. **Check overload relay** (motor loads): |
| + | - May be tripped - reset and retest |
| + | - May need adjustment or replacement |
| + | 5. **Test load directly** (bypass relay): |
| + | - **CAUTION:** Only if qualified for electrical work |
| + | - Temporarily wire load directly to power |
| + | - **If load works:** Relay contacts bad - replace relay |
| + | - **If load doesn't work:** Load failed (motor, heater, etc.) |
| + | |
| + | ### RELAY STUCK ON / WON'T TURN OFF |
| + | 1. **Command relay OFF** from controller |
| + | 2. **Measure coil voltage:** Should be 0VAC when OFF |
| + | - **If still has voltage:** Controller output stuck ON |
| + | 3. **Listen for click:** Should click when commanded OFF |
| + | - **If no click:** Contacts welded shut - replace relay immediately |
| + | 4. **Measure across load:** Should be 0V when relay OFF |
| + | - **If still has voltage:** Contacts stuck closed - **SAFETY HAZARD** |
| + | 5. **REPLACE RELAY** if contacts won't open (fire hazard) |
| + | |
| + | ### RELAY CHATTERS / RAPID CLICKING |
| + | 1. **Low coil voltage:** |
| + | - Measure at relay coil: Should be 24VAC ±10% |
| + | - **If <21V:** Voltage drop in wiring or controller issue |
| + | - Check wire gauge adequate (18AWG minimum) |
| + | 2. **Loose coil connections:** |
| + | - Check terminals tight |
| + | 3. **High contact load:** |
| + | - Relay undersized for load |
| + | - Measure load current with clamp meter |
| + | - **If exceeds relay rating:** Replace with higher-rated relay |
| + | 4. **Defective relay:** |
| + | - Replace with known good relay to test |
| + | |
| + | ### CONTACTS BURNED / PITTED |
| + | 1. **Caused by:** Switching high inrush current (motors, transformers) |
| + | 2. **Indicators:** |
| + | - Black/brown deposits on contacts |
| + | - High resistance when closed (>1 ohm) |
| + | - Arcing visible when switching |
| + | 3. **Solutions:** |
| + | - Replace relay |
| + | - Add inrush current limiting (soft starter for motors) |
| + | - Use relay with higher contact rating |
| + | - Consider solid-state relay for frequent switching |
| + | |
| + | ### OVERLOAD RELAY TRIPPING (Motor Loads) |
| + | 1. **NOT a relay problem** - motor or overload issue |
| + | 2. Check motor current with clamp meter: |
| + | - Compare to motor nameplate FLA |
| + | - **If >FLA:** Motor overloaded, mechanical problem, or failing |
| + | 3. Check overload relay setting: |
| + | - Should be set to motor FLA |
| + | - **If too low:** Nuisance tripping - adjust |
| + | 4. Check for motor problems: |
| + | - Bearing failure, seized load, phase loss |
| + | 5. **If motor current normal:** Overload relay may be defective |
| + | |

| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Relay sizing:** Always size contacts for 125% of load current (safety margin) |
| + | ✓ **Motor loads:** Relay must be rated for "Pilot Duty" or motor HP |
| + | ✓ **Inrush current:** Motors draw 5-8× FLA on startup - relay must handle this |
| + | ✓ **Contact life:** Typical 100,000 operations, less with high current |
| + | ✓ **Coil voltage:** 24VAC most common, verify matches controller output |
| + | ✓ **Contact configuration:** SPST most common (single switch), SPDT for changeover |
| + | ✓ **Overload protection:** Separate overload relay required for motor loads (NEC) |
| + | ✓ **Wire neutral:** Never switch neutral (code violation) - only switch hot leg |
| + | ✓ **Stuck contacts:** Fire hazard - replace immediately if contacts won't open |
| + | ✓ **Contact cleaning:** Don't file contacts - replace relay if pitted/burned |
| + | ✓ **Solid-state relays:** Consider for high-cycle applications (>10,000 ops/day) |
| + | ✓ **Status feedback:** Use auxiliary contacts or current sensor for proof of operation |

| + | |
| + | ✓ **Space sensors reading high:** Check if in direct sun or near heat source |
| + | ✓ **Duct sensors inaccurate:** Verify insertion depth (1/3 width for spot sensing) |
| + | ✓ **Outdoor sensors erratic:** Ensure north-facing, away from exhaust/relief dampers |
| + | ✓ **Immersion sensors slow:** Normal - thermal mass requires 15-20 min to respond |
| + | ✓ **All sensors offset same amount:** Apply controller calibration offset, don't replace |
| + | ✓ **Shielded cable:** Ground shield at controller end ONLY (not both ends) |
| + | ✓ **10K Type II vs Type III:** Most controllers auto-detect, but verify in config |

| + | --- |
| + | |
| + | ## TROUBLESHOOTING |
| + | |
| + | ### NO POWER / ACTUATOR DEAD |
| + | 1. Measure supply voltage at actuator: 24VAC/VDC or 120VAC ±10% |
| + | 2. Test continuity of power wiring end-to-end: <5 ohms |
| + | 3. Check terminal connections tight |
| + | 4. Verify polarity (DC circuits) |
| + | 5. Listen for motor sound when commanded (should hear humming) |
| + | 6. **If voltage present but no sound:** Replace actuator (motor failed) |
| + | |
| + | ### ACTUATOR RUNS BUT VALVE DOESN'T MOVE |
| + | 1. **Check coupling:** May have loosened or stripped |
| + | 2. **Manually try to move stem:** Should feel resistance from actuator |
| + | 3. **Check valve stem:** May be seized or broken |
| + | 4. **If coupling loose:** Tighten or replace |
| + | 5. **If stem seized:** Valve needs service/rebuild |
| + | 6. **If stem broken:** Valve replacement required |
| + | |
| + | ### ACTUATOR MOVES BUT INCORRECT POSITION |
| + | 1. Verify control signal at actuator terminals |
| + | 2. **If signal correct but position wrong:** Check stroke limits |
| + | 3. Adjust stroke limits to match valve travel |
| + | 4. Verify coupling not slipping on stem |
| + | 5. Check position feedback wiring (if equipped) |
| + | 6. **If feedback wrong:** Check feedback wire, verify at controller |
| + | |
| + | ### ACTUATOR STALLS OR BINDS |
| + | 1. Check valve for physical problems: |
| + | - Stem bent or damaged |
| + | - Internal valve parts seized or broken |
| + | - Packing gland too tight |
| + | 2. Measure current draw: >300mA indicates overload |
| + | 3. **If overcurrent:** Valve too large for actuator or valve needs service |
| + | 4. **If binding specific position:** Adjust stroke limits |
| + | 5. **If generally binding:** Service valve or replace actuator with higher force |
| + | |
| + | ### SLOW MOVEMENT |
| + | 1. Measure supply voltage under load: Should stay ±10% |
| + | 2. Check for voltage drop in long wire runs |
| + | 3. Verify control signal stable |
| + | 4. Listen for motor sounds (grinding indicates wear) |
| + | 5. **If voltage drops:** Increase wire gauge |
| + | 6. **If motor sounds bad:** Replace actuator (gearbox failing) |
| + | |
| + | ### WATER LEAKING FROM VALVE STEM |
| + | 1. **NOT an actuator issue** - packing gland needs adjustment |
| + | 2. Slightly tighten packing nut (1/4 turn at a time) |
| + | 3. **If still leaking:** Packing needs replacement (coordinate with plumber) |
| + | 4. **CAUTION:** Over-tightening can bind valve stem |
| + | |
| + | ### VALVE WON'T CLOSE FULLY (Leaking Thru) |
| + | 1. **NOT typically actuator issue** - valve seat worn or damaged |
| + | 2. Verify actuator reaching full closed position (0% command) |
| + | 3. If actuator at 0% but water still flowing: Valve needs service/replacement |
| + | 4. **Temporary workaround:** Slightly over-close using controller offset (if available) |
| + | |
| + | ### ACTUATOR WON'T RETURN TO FAIL-SAFE (SR) |
| + | 1. Remove power and manually feel spring tension |
| + | 2. **If no spring:** Spring broken - replace actuator |

| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Actuator sizing:** 90-150 lbs for 2-way valves up to 2", 200-500 lbs for larger or 3-way valves |
| + | ✓ **Spring return vs non-spring:** SR for fail-safe (cooling valves close on power loss) |
| + | ✓ **Normally Open vs Normally Closed valve:** Must match application (NC for cooling typical) |
| + | ✓ **2-10V vs 0-10V:** 2-10V preferred - provides broken wire detection |
| + | ✓ **Stroke time:** Longer stroke time (90-180 sec) prevents water hammer |
| + | ✓ **Hot pipes:** Route wiring away from pipes >140°F to prevent insulation damage |
| + | ✓ **Valve cycling:** Excessive cycling (>6 per hour) indicates PID loop needs tuning |
| + | ✓ **Position feedback:** Essential for accurate control - use 4-wire actuator |
| + | ✓ **Packing gland:** Light leak from packing is normal, but excessive leak needs adjustment |
| + | ✓ **Manual override:** Use during commissioning to verify valve operation |
| + | ✓ **Glycol systems:** More viscous than water, may require longer stroke time |

| + | - **Digital Run Input:** DI1, Run, Start/Stop |
| + | - **Common:** COM, GND, Digital Common |
| + | - **Status Outputs:** RO1, RO2 (relay outputs for status) |
| + | |
| + | **STEP 1: Wire Analog Speed Command (0-10VDC)** |
| + | |
| + | 1. **Locate VFD analog input terminals:** |
| + | - Typically labeled: AI+, AI-, or AIN+, AIN- |
| + | - Check VFD manual for exact terminal numbers |
| + | |
| + | 2. **Connect from controller:** |
| + | - Controller AO+ (0-10V output) → VFD AI+ terminal |
| + | - Controller COM → VFD AI- terminal |
| + | - Tighten terminals: 7-9 in-lbs |
| + | - **Use shielded cable if run >50 feet** |
| + | - Ground shield at controller end only (not both ends) |
| + | |
| + | 3. **Verify voltage range:** |
| + | - Most VFDs default to 0-10V input |
| + | - Some can be configured for 4-20mA - verify setting |
| + | |
| + | **STEP 2: Wire Digital Run Command (Start/Stop)** |
| + | |
| + | 1. **Locate VFD digital input terminals:** |
| + | - Typically labeled: DI1, Run, or Start |
| + | - May require jumper removal (VFD ships with local control enabled) |
| + | |
| + | 2. **Connect from controller:** |
| + | - **Option A: Dry contact (relay):** |
| + | * Controller relay NO contact → VFD DI1 and COM |
| + | * When relay closes = VFD runs |
| + | - **Option B: Digital output (24VDC):** |
| + | * Controller DO+ → VFD DI1 |
| + | * Controller COM → VFD COM |
| + | * When DO energized = VFD runs |
| + | |
| + | 3. **Verify input voltage:** |
| + | - Most VFDs accept 24VDC digital inputs |
| + | - Some require configuration for voltage vs contact |
| + | |
| + | **STEP 3: Wire Status Feedback (Optional but Recommended)** |

| + | |
| + | 5. **Acceleration/Deceleration Ramps:** |
| + | - Accel time: 10-30 seconds typical (prevents high inrush) |
| + | - Decel time: 10-30 seconds typical (prevents water hammer) |
| + | |
| + | 6. **Motor Nameplate Data:** |
| + | - Enter motor voltage, FLA, RPM, Hz from motor nameplate |
| + | - VFD uses for protection and efficiency |
| + | |
| + | 7. **Status Relay Configuration:** |
| + | - Program RO1 for "Running" or "Fault" |
| + | - Set NO or NC operation |
| + | |

| + | |
| + | ### VFD RUNS BUT WRONG SPEED |
| + | 1. **Measure speed command voltage:** |
| + | - Should be 0-10V at VFD AI+ terminal |
| + | - **If wrong voltage:** Controller output problem |
| + | 2. **Check VFD parameter:** |
| + | - Verify AI1 set for 0-10VDC (not 4-20mA) |
| + | - Check min/max speed limits |
| + | 3. **Check wiring:** |
| + | - Verify AI+ and AI- not reversed |
| + | - Check for voltage drop in long wire runs |
| + | 4. **Calibrate:** Some VFDs allow analog input calibration |
| + | |
| + | ### MOTOR ROTATION WRONG DIRECTION |
| + | 1. **STOP immediately** - Wrong rotation can damage equipment |
| + | 2. **Lock out VFD power** |
| + | 3. **Swap two motor leads:** |
| + | - Have electrician swap any two of the three motor leads |
| + | - Example: Swap L1 and L2 at VFD output or motor terminals |
| + | 4. **Restore power and retest** |
| + | 5. **Verify:** Rotation now correct |
| + | |
| + | ### VFD SHOWS FAULT / TRIPS |
| + | **Common VFD Faults:** |
| + | |
| + | **Overcurrent (OC):** |
| + | - Motor overloaded or mechanical binding |
| + | - Accel time too short (increase to 20-30 sec) |
| + | - Check motor current vs FLA rating |
| + | - **If current >FLA:** Motor or load problem |
| + | |
| + | **Overvoltage (OV):** |
| + | - Decel time too short (increase to 20-30 sec) |
| + | - Regenerative load (fan coasting = backfeeds VFD) |
| + | - Add braking resistor if frequent overvoltage |
| + | |
| + | **Undervoltage (UV):** |
| + | - Incoming power voltage too low |
| + | - Check supply voltage at VFD input terminals |
| + | - Voltage sag during motor start |
| + | |
| + | **Ground Fault:** |
| + | - Motor insulation failure |
| + | - Test motor with megohmmeter (should be >1 megohm to ground) |
| + | - Check motor cable for damage |
| + | |
| + | **Overtemperature:** |
| + | - VFD overheating (check cooling fans) |
| + | - Ambient temperature too high (>104°F) |
| + | - Blocked ventilation (clean filters) |
| + | |
| + | **Phase Loss:** |
| + | - Missing input phase (L1, L2, or L3) |
| + | - Check fuses, breakers, contactors |
| + | - Measure voltage at VFD input (all 3 phases present?) |
| + | |
| + | ### VFD RUNS BUT MOTOR DOESN'T |
| + | 1. **Check VFD output:** |
| + | - Measure voltage at T1, T2, T3 (VFD motor terminals) |
| + | - Should see voltage when VFD running |
| + | - **If no voltage:** VFD output problem |
| + | 2. **Check motor connections:** |
| + | - Verify motor cable connected |
| + | - Check for loose or broken wires |
| + | 3. **Check motor contactor** (if present): |
| + | - Some installations have contactor between VFD and motor |
| + | - Verify contactor energized when VFD runs |
| + | 4. **Test motor:** |
| + | - May be motor problem (bearing seizure, winding failure) |
| + | - Megohmmeter test motor insulation |
| + | |
| + | ### STATUS FEEDBACK NOT WORKING |
| + | 1. **Check VFD relay output:** |
| + | - Verify RO1 configured for "Running" status |
| + | - Test continuity across relay contacts when running |
| + | - **If open when should be closed:** VFD relay not operating |
| + | 2. **Check wiring:** Verify connections at controller BI |
| + | 3. **Check controller config:** BI configured as NO or NC? |
| + | |
| + | ### MOTOR STALLS AT LOW SPEED |
| + | 1. **Increase minimum speed:** Typical 20-30% |
| + | 2. **Check V/Hz curve:** May need boost voltage at low Hz |
| + | 3. **Check load:** Motor may be oversized for load |
| + | |
| + | ### EXCESSIVE NOISE OR VIBRATION |
| + | 1. **Check motor mounts:** Loose or damaged |
| + | 2. **Fan unbalanced:** Check fan blades and wheel |
| + | 3. **VFD switching frequency:** Increase carrier frequency (reduces audible noise) |
| + | 4. **Mechanical resonance:** Avoid certain speed ranges |

| + | --- |
| + | |
| + | ## COMMON ISSUES & TIPS |
| + | |
| + | ✓ **Motor rotation:** ALWAYS verify correct rotation on first startup - wrong direction damages equipment |
| + | ✓ **Accel/decel times:** 10-30 seconds typical - prevents overcurrent and water hammer |
| + | ✓ **Minimum speed:** 20-30% prevents motor stalling and unstable operation |
| + | ✓ **Shielded cable:** Use for analog speed command if >50 feet - prevents interference |
| + | ✓ **Ground shield once:** At controller end only, never both ends (prevents ground loops) |
| + | ✓ **Control mode:** Must be set to "External" or "Terminal" control |
| + | ✓ **Parameter backup:** Save VFD parameters to file after programming |
| + | ✓ **VFD sizing:** Must match motor HP and voltage - undersized VFD trips on overcurrent |
| + | ✓ **Motor cable:** VFD-rated cable required - standard motor wire may not be adequate |
| + | ✓ **Bypass contactor:** Allows manual operation if VFD fails (emergency backup) |
| + | ✓ **Energy savings:** VFD reduces fan/pump energy by 50-70% at part load (affinity laws) |
| + | ✓ **Soft start:** VFD eliminates need for separate soft starter |
| + | ✓ **Remote monitoring:** Enable Modbus/BACnet for advanced diagnostics |
