Application
The CV series controllers are designed for variable air volume (VAV) box applications. These controllers feature 14 preloaded standard applications, enabling operation of standard VAV box equipment with a proven energy-efficient sequence of operation without requiring programming. For information on configuring a CV series controller to use a preloaded application, refer to the 'Setting a preloaded application' section. These controllers are also fully programmable using the Controller Configuration Tool (CCT), offering flexibility to create custom control sequences.
CV series controllers include an integral damper actuator, a digital Differential Pressure Transmitter (DPT) sensor, and a 32-bit microprocessor. The CVM03050-0P and CVE03050-0P models feature an integral potentiometer to sense the actual VAV box damper position. For information on configuring an application with integrated actuator feedback, refer to the CV Series Actuator Feedback Application Note (LIT-12013631).
CV series controllers also include an integral real-time clock, allowing them to monitor and control schedules, calendars, and trends. They can operate for extended periods as stand-alone controllers when offline from the Facility Explorer system network. These controllers connect easily to wired and wireless network sensors for zone and discharge air temperature sensing. Their compact size facilitates quick field installation and efficient use of space without compromising control performance.
Communications Protocols
CV series controllers can communicate using multiple protocols depending on the model and configuration. CVE controllers utilize the BACnet® Secure Connect (BACnet/SC) or BACnet/IP communication protocol. CVM controllers use the BACnet MS/TP, N2, or wireless communications protocols, with the addition of ZFR183x Pro Wireless Field Bus Routers. Equipment Controllers operating in BACnet/SC, BACnet/IP, or BACnet MS/TP communication modes are BACnet network-compliant devices. The BACnet protocol is a standard recognized by ANSI, ASHRAE, and the International Standards Organization (ISO) for building controls.
Controllers operating in N2 mode can be used to maintain or modernize sites with legacy Johnson Controls® controllers. For installation and commissioning support, and tips for efficient and safe replacement, refer to the Modernization Guide for Legacy N2 Controllers (LIT-12012005) and the controller-specific documentation. For information about mapping N2 Objects in controllers with switchable communications protocols, refer to the N2 Compatibility Options chapter of the Controller Tool Help (LIT-12011147).
To configure CVM controllers for the N2 communications protocol, see 'Configuring N2 communications (CVM models only)'. To configure CVM controllers for wireless communications, see 'Configuring wireless communications (CVM models only)'.

Mounting
Observe the following guidelines when mounting a CVM/CVE controller:
- Ensure that the mounting surface can support the controller and any user-supplied enclosure.
- Mount the controller on a hard, even surface whenever possible.
- Use shims or washers to mount the controller securely and evenly on the mounting surface.
- Mount the controller in an area free of corrosive vapors that matches the ambient conditions specified in the Technical specifications section.
- Provide sufficient space around the controller for cable and wire connections and adequate ventilation through the controller (at least 50 mm [2 in.] on the top, bottom, sides, and front of the controllers).
- Do not mount the controller in areas where electromagnetic emissions from other devices or wiring can interfere with controller communication.
- Avoid mounting the controller on surfaces with excessive vibration.
❗ Important: When the air supply to the VAV box is below 10°C (50°F), ensure that any condensation on the VAV box, particularly on the damper shaft, does not enter the controller electronics. Mount the controller vertically above the damper shaft to allow any shaft condensation to fall away from the controller. Additional measures may be required in some installations.
On panel or enclosure mount applications, observe these additional guidelines:
- Do not install the controller in an airtight enclosure.
- Mount the controller so that the enclosure walls do not obstruct cover removal or ventilation through the controller.
- Mount the controller so that the power transformer and other devices do not radiate excessive heat to the controller.
Controller Mounting Positions
To mount the CVM/CVE controllers, complete the following steps:
- Set all the switches on the equipment controller to their known settings.
- Place the controller in the proper mounting position on the damper shaft so that the wiring connections are easily accessible. Make sure the controller base is parallel to the VAV box (perpendicular to the damper shaft). If needed, use a spacer to offset tipping of the controller caused by the shaft bushings. ? Note: Use the alignment marks to center the captive spacer to ensure sufficient CVM/CVE movement in either direction.
- Secure the self-drilling No.10 screw through the captive spacer with a power screwdriver and 100mm (4in.) extension socket. Alternatively, use a punch to mark the position of the shoulder washer, and then drill a hole into the VAV box using a 3.5mm (9/64in.) drill bit. Insert the mounting screw and tighten against the spacer. ❗ Important: Do not overtighten the screw, or the threads may strip. If mounting to the VAV box, ensure the screws do not interfere with damper blade movement.
- Locate the damper position using the typical marking on the end of the damper shaft as shown in the figure below.
- Note the direction, clockwise (CW) or counterclockwise (CCW), required to close the damper. Grasp the damper shaft firmly with pliers, and either manually close the damper for 90° boxes or manually open the damper for 45° or 60° boxes.
- Push down and hold the Manual Override button and turn the controller coupler until it contacts the mechanical end-stop at either the full-closed (90° boxes) or full-open (45° and 60° boxes) position.
- If the damper for a 90° box closes CCW, rotate the coupler to the CCW mechanical limit. If the damper for a 90° box closes CW, rotate the coupler to the CW mechanical limit. The open end-stop is automatically set for 90° boxes. For 45° and 60° boxes, provide hard stops at both full-closed and full-open damper positions. If the controller is installed at the full-open position, the controller provides the open stop for 45° and 60° boxes. The closed damper seal provides the full-closed stop. ? Note: The integrated actuator has a stroke time of 60 seconds for 90° of travel with a 60Hz power source. The stroke time is the duration (in seconds) for the actuator to move from fully closed to fully opened or vice versa. For proper operation, the actuator stroke time must be configured in the CCT application based on the actual time it takes the actuator to drive the damper. The default setting is 60 seconds (for 90° VAV boxes). For 45° and 60° VAV boxes, the actuator stroke time must be adjusted. Refer to Controller Tool Help (LIT-12011147) for instructions on setting the actuator stroke time in the application.
- All models are compact and easily installed on VAV boxes. They accommodate either a round shaft up to 13 mm in diameter or a 10 mm square shaft. Tighten the square coupler bolt to the shaft using an 8 mm (5/16 in.) wrench or 10 mm (3/8 in.) 12-point socket. Tighten to 10.5 to 11.5 N·m (95 to 105 lb·in).
- Loop the pneumatic tubing (supplied by field personnel) to include a trap for condensation. Attach the needed length of tubing to the dual port fitting on the controller and the other ends of the tubing to the pressure transducer in the VAV box application. ? Note: The CVM/CVE uses a digital pressure sensor with bidirectional flow operation, allowing connection of high- and low-pressure DP tubes to either barbed fitting on the controller. No specific high- or low-side connection is required when attaching tubing to the barbed fittings on the CVM/CVE.
- Push the Manual Override button, and turn the actuator coupling manually to ensure the actuator can rotate from full-closed to full-open positions without binding.
- Complete the mounting by rotating the damper to the full-open position.

Wiring
Observe the following guidelines when wiring a CVM/CVE controller:
⚠️ CAUTION
Risk of Property Damage. Rotate the damper to the full-open position before starting the air handler. Failure to rotate the damper to the full-open position may result in damage to the VAV box or ductwork when the air handler is started.
⚠️ ATTENTION
Risque de dégâts matériels. Faire pivoter le registre pour le placer en position d'ouverture complète avant de démarrer l'unité de traitement d'air. Le non-respect de cette directive risque d'endommager le caisson de l'unité à volume d'air variable (VAV) ou le réseau de conduites au démarrage de l'unité de traitement d'air.
⚠️ CAUTION
Risk of Electric Shock. Disconnect the power supply before making electrical connections to avoid electric shock.
⚠️ ATTENTION
Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge électrique.
❗ Important: Do not connect supply power to the controller before finishing wiring and checking all wiring connections. Short circuits or improperly connected wires can result in damage to the controller and void any warranty.
❗ Important: Do not exceed the controller electrical ratings. Exceeding controller electrical ratings can result in permanent damage to the controller and void any warranty.
❗ Important: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations.
❗ Important: Electrostatic discharge can damage controller components. Use proper electrostatic discharge precautions during installation, setup, and servicing to avoid damaging the controller.
For information on configuring and wiring a BACnet/SC or BACnet/IP network, refer to the Facility Explorer IP Networks for BACnet/IP Controllers Configuration Guide (LIT-12012980). For detailed information about configuring and wiring an MS/TP Bus, FC Bus, or SA Bus, refer to the FX MS/TP Communications Bus Technical Bulletin (LIT-12011670). For detailed information about wiring an N2 network, refer to the N2 Communications Bus Technical Bulletin (LIT-636018).
Terminal Blocks and Bus Ports
See Physical features for terminal block and bus port locations on the CVM/CVE controllers. Observe the following guidelines when wiring a CVM/CVE controller.
Input and Output Terminal Blocks
CV series controllers have removable input and output terminal blocks. Input terminals are located on the bottom of the controller, and output terminal blocks are located on the top. For information about removing a terminal block, see 'Removing a terminal block'. For more information about I/O terminal functions, requirements, and ratings, see Table 5.
BACnet/SC or BACnet/IP Ethernet Network Topology for CVE Controllers
CVE controllers can connect to a BACnet/SC or BACnet/IP building automation network in multiple ways: as daisy-chained devices, as part of a star (home run) network, or as part of a ring network. To daisy-chain CVE controllers, connect them to the bus supervisor in a chain, using the Ethernet cable connecting to the CVE at the ETH-1 or ETH-2 port, and connecting to the next device from the other port. Benefits of daisy-chained networks include less physical wiring and easy addition of new devices.
In a star network, each CVE controller connects via Ethernet cable directly back to a main switch. This configuration reduces the possibility of network failure but requires more wiring.
A ring network is a chain of controllers virtually closed by a software component in an Ethernet switch. Not all switches support ring topology. The dual-port controller from Johnson Controls supports Media Redundancy Protocol (MRP). With MRP, a ring of Ethernet devices can overcome any single communication failure with a faster recovery time than non-ring (daisy-chain or star) architectures.
For more information on network topologies for IP Controllers, see Facility Explorer IP Networks for BACnet/IP Controllers Configuration Guide (LIT-12012980).
FC Bus Terminal Block on CVM Controllers
The FC Bus terminal block is a blue, removable, 4-pin terminal block that fits into a board-mounted pin header. When connecting the CVM to the FC Bus, wire the bus terminal blocks on the controller and other FC Bus devices in a daisy-chain configuration using 3-wire twisted, shielded cable as shown in Figure 5. For more information about FC Bus terminal functions, requirements, and ratings, see Table 7.
| Description | |
|---|---|
| 1 | Wiring for a terminating device on the FC Bus. |
| 2 | FC Bus terminal blocks. |
| 3 | Wiring for a daisy-chained device on an FC Bus segment. |
| 4 | Connects to the next device on the FC Bus. |
| 5 | Isolated Shield connection terminal. |
[Diagram placeholder for FC Bus terminal block wiring]
? Note: The Shield terminal (SHD) on the FC Bus terminal block is isolated and can be used to connect the cable shields on the bus (Figure 5).
SA Bus Terminal Block
The SA Bus terminal block is an orange, removable, 4-pin terminal block with +15 VDC that fits into a board-mounted pin header. When connecting an SA Bus device to the controller, wire the SA Bus terminal block on the controller and other SA Bus devices in a daisy-chain configuration using 4-wire twisted, shielded cable as shown in Figure 6. For more information about SA Bus terminal functions, requirements, and ratings, see Table 7.
| Description | |
|---|---|
| 1 | Wiring for a terminating device on SA Bus. |
| 2 | SA Bus terminal blocks. |
| 3 | Wiring for a daisy chained device on SA Bus. |
| 4 | Cable shield connection. ? Note: Connect the shields to ensure they are continuous the entire length with only one ground location. |
| 5 | Connects to the next device on the SA Bus. |
[Diagram placeholder for SA Bus terminal block wiring]
? Note: Stranded, 4-wire (2 twisted pair) shielded cable. One twisted pair is the + and - leads. The second pair is COM and POWER.
? Note: Do not use the modular SA Bus port and the terminal block SA Bus simultaneously. Only use one of these connections at a time.
? Note: The CVM/CVE controller is the EOL for the SA Bus.
Sensor (SA Bus) Port
The Sensor (SA Bus) port is an RJ-12, 6-position modular jack that provides a connection for the Mobile Access Portal (MAP) Gateway, the VAV Balancing Tool, specified network sensors, or other SA Bus devices with RJ-12 plugs. A F4-DLK0350 or FX-DIS1710 Local Controller Display can also be connected to the SA Bus port.
? Note: Do not use the modular SA Bus port and the terminal block SA Bus simultaneously. Only use one of these connections at a time.
The Sensor port is connected internally to the SA Bus terminal block. For more information about Sensor port functions, requirements, and ratings, see 'Communications bus and supply power terminal blocks, ratings, and requirements'.
Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray, removable, 2-pin terminal block that fits into a board-mounted pin header on the upper left of the controller. Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the terminal block as shown in Figure 8. For more information about Supply Power terminal functions, requirements, and ratings, see Table 7.
| Description | |
|---|---|
| 1 | Supply power terminal block. |
| 2 | Supply power terminal header. |
| 3 | Wires from Johnson Controls 24 VAC, class 2 power transformer. |
| 4 | COM (Brown wire). |
| 5 | 24 VAC (Orange wire). |
[Diagram placeholder for 24 VAC supply power terminal block wiring]
? Note: The supply power wire colors may be different on transformers from other manufacturers. Refer to the transformer manufacturer's instructions and the project installation drawings for wiring details.
❗ Important: Connect 24 VAC supply power to the controller and all other network devices so that transformer phasing is uniform across the network devices. Powering network devices with uniform 24 VAC supply power phasing reduces noise, interference, and ground loop problems. The controller does not require an earth ground connection. However, when grounding the secondary of the 24 VAC transformer is required, only one connection to ground must be made near the transformer. See Figure 9.
⚠️ CAUTION
Risk of Property Damage: Do not apply power to the system before checking all wiring connections. Improper wiring of this terminal may cause a short circuit across the 24 VAC power supply. A short circuit may result in a tripped circuit breaker or blown fuse. If using a transformer with a built-in fuse, the transformer may need to be replaced.
? Note: The order of the HOT and COM terminals on the CV series controllers is reversed from the order of the terminals on the CG series controllers.

Configuring N2 Communications (CVM Models Only)
About this task: N2-capable controllers support the full range of possible N2 device addresses provided by the N2 protocol standard (1-254).
To configure a CVM controller to communicate using the N2 protocol, complete the following steps:
- Disconnect the 24 VAC supply from the controller.
- Set the address switches to the desired N2 address. For details about setting a device address, see 'Setting the device address on CVM models'.
- Reconnect the 24 VAC supply to the controller.
- Using an SA Bus connection, download the firmware and controller application file configured for N2 to the controller.
Switching the Communications Protocol from N2 to MS/TP
About this task: For N2 sites converting to BACnet MS/TP, you can switch the communications protocol of N2-configured CVM controllers back to BACnet MS/TP.
To switch the CVM controller operating in N2 mode back into BACnet MS/TP mode, complete the following steps:
- Disconnect the 24 VAC supply from the controller.
- Set the address switches to the desired BACnet MS/TP address. For details about setting a device address, see 'Setting the device address on CVM models'.
- Reconnect the 24 VAC supply to the controller.
- Using an SA Bus connection, download a controller application file configured for BACnet MS/TP to the controller.
Configuring Wireless Communications (CVM Models Only)
About this task: To configure a controller for use with the ZFR Pro Series Wireless Field Bus system, complete the following steps:
- Disconnect the 24 VAC supply from the controller.
- Wire the input/output terminals and SA Bus. ? Note: In wireless network applications, do not connect any wires to the FC Bus terminal block. (Connect the SA/FC terminal block on an expansion module to an SA Bus only.)
- ❗ Important: Before the CVM controller is powered on, connect the ZFR Pro Wireless Field Bus Router to the FC Bus port (RJ-12 modular jack) on the front of the controller.
- Ensure that the controller's rotary switches are set to the correct device address. For details about setting a device address, see 'Setting the device address on CVM models'.
- Reconnect the 24 VAC supply to the controller.
For more information about the FX-ZFR 1800 Wireless Field Bus system, refer to the FX-ZFR Series Wireless Field Bus System Bulletin (LIT-12011660). For more information on the FX-ZFR Pro Wireless Field Bus system, refer to the WNC1800/FX-ZFR182x Pro Series Wireless Field Bus System Bulletin (LIT-12012378).
Setting the Device Address on CVM Models
The CVM controllers are manager devices on MS/TP (FC or SA) Buses. Before operating controllers on a bus, you must set a valid and unique device address for each controller on the bus. The following table describes the valid rotary switch device addresses for communications bus applications.
| FC Bus Communication Mode | Valid Device Address Range |
|---|---|
| Wired MS/TP communication | 4-127 ? Note: Addresses 0-3 are reserved and not for use on equipment controllers. |
| ZFR Pro Wireless communication | 4-127 ? Note: Addresses 0-3 are reserved and not for use on equipment controllers. |
| N2 communication | 1-254 ? Note: Addresses 0 and 255 are reserved and not for use on equipment controllers. |
The device address is a decimal address set using three rotary switches located at the top of the controller. The numbers are ordered from left to right: 100s, 10s, and 1s, as shown in Figure 11. In the figure, the switches are set to 1 2 3, designating this controller's device address as 123.
[Diagram placeholder for Rotary switch block]
The device address must match the device address defined in the Controller Configuration Tool (CCT) under Define Hardware > Network Settings.
To set the device addresses on controllers, complete the following steps:
- Set a unique and sequential device address for each of the devices connected on the FC or SA, starting with device address 4.
- To ensure the best bus performance, set sequential device addresses with no gaps in the device address range (e.g., 4, 5, 6, 7, 8, 9, and so on). The devices do not need to be physically connected on the bus in their numerical device address order.
- Write each controller's device address on the white label below the Device Address Rotary Switch Block on the controller's cover.
Setting the Controller Number for CVE Models
The rotary switches on the CVE models are used to set the controller number. The controller number can be utilized to physically identify the controller and relate it to the building drawings. The factory default BACnet device ID is calculated from the controller number plus 2,000,000. Each equipment controller on a BACnet/SC or BACnet/IP network must have a unique BACnet device ID on the subnet where it resides for proper identification and communication. To ensure a unique value, the BACnet device ID should be configured in CCT rather than relying on this default calculation. This step is necessary for sites with over 1000 devices, as controller numbers may be duplicated.
The controller number is set using three rotary switches and can range from 000 to 999. The numbers are ordered from left to right: 100s, 10s, and 1s. In Figure 11, the switches are set to 1 2 3, designating this controller as controller number 123. The controller number can be written in the provided white squares for easier viewing from a distance.
Removing a Terminal Block
About this task: To remove a terminal block from the circuit board, complete the following steps:
? Note: You need a flat blade screwdriver to remove the terminal block.
- To prevent any possibility of damage from an accidental short, remove power from the controller.
- Underneath the terminal block, in the small gap between the bottom of the terminal block and the circuit board, insert the flat blade of the screwdriver.
- To detach the left-hand side of the terminal block, position the flat blade underneath the terminal block to the left, and push down the screwdriver handle. This uses the screwdriver as a lever to pry up the terminal block.
- To detach the right-hand side of the terminal block, position the flat blade underneath the terminal block to the right, and push down the screwdriver handle.
- If necessary, repeat steps 3 and 4 until the terminal block is removed.
[Diagram placeholder for Terminal block]
Setting the End-of-Line (EOL) Switch (CVM Models Only)
Each CVM controller has an EOL switch. When set to ON (up), it designates the CVM controller as a terminating device on the bus. See Physical features for the EOL switch location. The default EOL switch position is OFF (down).
[Diagram placeholder for End-of-Line Switch Positions]
To set the EOL switch on a CVM controller, complete the following steps:
- Determine the physical location of the controller on the FC Bus.
- Determine if the controller must be set as a terminating device on the bus. ? Note: For detailed information about EOL termination rules and EOL switch settings on FC Buses, refer to the FX MS/TP Communications Bus Technical Bulletin (LIT-12011670).
- If the controller is a terminating device on the FC Bus, set the EOL switch to ON. If it is not a terminating device, set the EOL switch to OFF.
When a controller is connected to power with its EOL switch set to ON, the amber EOL LED on the controller cover is illuminated.
Input and Output Wiring Validation
Controllers are shipped with a default cooling only, warm or cool adjust application. This default application can be used to perform wiring verification using the MAP Gateway, F4-DLK0350, or the FX-DIS1710-0 local controller display.
To perform wiring validation, ensure that the rotary switches are set to the desired address or controller number and that the input and output terminals are wired correctly. Apply power to the controller. The Fault LED behaves the same as during normal application load. When the Fault LED turns off, connect to the device using a MAP Gateway, F4-DLK0350, or FX-DIS1710-0 Local Display to view the points in the controller.
Commissioning the Controllers
To commission the controller, use the following procedure:
- With the desired application loaded in the controller, commission the VAV Box. Refer to the Controller Tool Help (LIT-12011147).
- Perform airflow balancing on the VAV box. Refer to the VAV Box Balancing Tool and Network Sensors Technical Bulletin (LIT-12011659).
- Perform commissioning checkout procedures. Refer to the Controller Tool Help (LIT-12011147).
Commission equipment controllers using the CCT software.
Commission controllers using the following connection types:
| Connection Type | CVM | CVE |
|---|---|---|
| MAP 4.2+/BACnet Router | X | X |
| Supervisor Passthru¹ | X | X |
| Direct Ethernet | X |
¹ Engines need to be at release 9.0 or later. These connection options require additional hardware listed in Table 12. Refer to the Controller Tool Help (LIT-12011147) and Controller Provisioning with Tools for detailed information about commissioning the controllers.
Firmware Package File
The FX-FCP-0 equipment controller firmware package files are required for CCT to configure and commission the controllers. The firmware package files also allow you to upgrade an existing controller to the latest firmware release available for that controller. Beginning at CCT Release 13, the firmware package files are orderable separately; they are not included with CCT. They are obtained from the HVAC Navigator FX Community site, and are loaded and licensed on the computer/server that is running CCT. For additional information about the firmware package files, refer to the CCT Installation Instructions (LIT-12011259).
Setting a Preloaded Application
You can configure a CVM/CVE controller to use one of the 14 preloaded applications using the MAP Gateway release 5.1 or later. Refer to Table 9 for the list of preloaded applications. The CVM/CVE controllers ship with the Cooling Only W/C Adjust application set by default.

Troubleshooting Equipment Controllers
Table 10 provides LED status indicator information for troubleshooting the controller. General troubleshooting provides additional troubleshooting information for possible problems.
? Note: If you experience short circuits in the 24 VAC power supply causing protective devices such as breakers or fuses to trip, ensure that the power connections on the controller are not reversed. The most common cause of this problem is when the 24 VAC power supply on the controller is reversed but not reversed on a connected secondary device.
LED Status and States
| LED Label | LED Color | Normal State | Descriptions of LED States |
|---|---|---|---|
| POWER | Green | On Steady | Off Steady = No power On Steady = Power is supplied by primary voltage |
| FAULT | Red | Off Steady | Blink - 2 Hz = Startup in progress, not ready for normal operation Rapid blink = SA Bus communications issue Off Steady = No faults On Steady = Device fault or no application loaded |
| FC BUS (CVM models) | Green | Blink - 2 Hz | Blink - 2 Hz = Data transmission (normal communication) Off Steady = No data transmission (auto baud in progress) On Steady = communication lost, waiting to join communication bus |
| SA BUS | Green | Blink - 2 Hz | Blink - 2 Hz = Data transmission (normal communication) Off Steady = No data transmission (N/A - auto baud not supported) On Steady = Communication lost; waiting to join communication bus |
| FC EOL (CVM models) | Amber | Off (except on terminating devices) | On Steady = EOL is active Off Steady = EOL is not active |
| ETH-1 (CVE models) | Green | Off | Off Steady = ETH-1 is not connected Blinking = ETH-1 connected and communicating |
| ETH-2 (CVE models) | Green | Off | Off Steady = ETH-2 is not connected Blinking = ETH-2 connected and communicating |
| FAULT and SA BUS | Red Green | Both blink six times in sequence = no valid firmware on the device (Applicable to CVE models only) |
General Troubleshooting
| Problem | Possible Cause and Correction | Verification | |
|---|---|---|---|
| Controller is OFF. | Cause: • Transformer has tripped: Power is at Primary of Transformer, 0V at Secondary. • Breaker/Fuse has tripped: Power is at Primary of Transformer, 24V at Secondary, 0V at Fuse/Breaker. | Cause: 1. Transformer is shorted. 2. 24 VAC powered sensor is not wired with the same polarity as the controller. 3. SA Bus device is not wired with the same polarity as the controller. Correction: 1. Ensure polarity of ~24 V COM / UI-C / +15VC/SA BUS COM on the controller, auxiliary devices, and I/O is the same. 2. Ensure BO-1, BO-2, and BO-3 terminals of binary outputs are not connected to ~24 VAC COM, and verify that BO-C terminals are not connected to ~24 VAC HOT (these terminals are internally sourced). 3. Verify the short circuit has been resolved with an ohm-meter. 4. Reset the breaker/fuse or replace the transformer. ? Note: When replacing the transformer, it is recommended to replace with a model that utilizes a resettable circuit breaker. A circuit breaker makes solving wiring problems easier. | 1. Disconnect the Secondary of the 24 VAC transformer. 2. Use an ohm-meter to measure between ~24 V HOT and COM; there must be no short circuit. ? Note: Some installations require the secondary of the transformer to be Earth Grounded. If this is the case, verify that the Earth Ground connection is valid and not shared between multiple pieces of equipment. |
| Configurable output - analog mode is invalid: 0-10 V output is set to 10–100%, but 0 V is at output terminals. Output is in protection mode, a state the analog portion of the configurable output goes into when it detects a wiring problem. The analog output is set to 0% regardless of the command whenever a wiring fault is detected. | Cause: There is a power polarity mismatch between the connected device and the configurable output. Correction: Ensure polarities of ~24 V COM/CO-C match and that the connected end device uses the same polarity. | 1. Measure the output and verify that it matches the command. 2. Disconnect the connected device and verify the commanded value is present. | |
| Configurable output - analog mode is invalid: 0-10V output has an undesirable offset of up to 1 V. The Common Reference is incorrect. | Cause: The CO-C terminal is not connected. Correction: Connect the CO-C terminal of the configurable output to the common of the connected end device. | 1. Measure the output and verify that it matches the command. 2. Disconnect the connected device and verify the commanded value is present. |
