Operation: Respond to Alarms
Displayed Alarm Message | Action Required |
|
|
Remote Sensor Added | • Check the CAN bus connection to the remote sensors. |
| • Disregard if you added the remote sensor. |
|
|
Replace Steam Cylinder | • Replace the steam cylinder. |
| • Clean the steam cylinder (if your System is equipped with reusable |
| humidifier cylinders). |
|
|
Return Sensor Fail | • Verify that there is a proper CAN connection between the sensors and the |
| user interface box. |
| • Replace the sensor assembly. |
|
|
Secondary Sensors Failed | • Verify that there is a proper CAN connection between the sensors and the |
| user interface box. |
| • Replace the sensor assembly. |
|
|
Smoke Detected | • Follow the appropriate facility emergency protocol. NOTE: The purpose of |
| the smoke sensor is to warn you of possible equipment damage. It is NOT |
| intended to provide a smoke alarm system to protect the facility and the lives |
| of its occupants. |
| • Confirm the wiring connections are secured to the wiring harness. |
| • Ensure smoke head and |
| • Ensure that there is not dirt or dust on the smoke head. Use pressurized air to |
| clean the smoke head chamber. |
| • Replace the smoke detector. |
|
|
Supply Sensor Fail | • Verify that there is a proper CAN connection between the sensors and the |
| user interface box. |
| • Replace the sensor assembly. |
|
|
Supply Temperature High | • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the Module to control the temperature after |
| • Verify that the supply air temperature alarm threshold is set above the cool |
| and reheat setpoints. |
| • Verify that there is proper airflow through the Module (check the pressure |
| drop across the evaporator coil). |
| • Ensure that the cool mode is enabled. |
| • Ensure that the cool mode is not disabled because of an active |
| input mapped to nonessential lockout. |
|
|
Supply Temperature Low | • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the Module to control the temperature after |
| • Verify that the Module is configured and equipped for the reheat mode. |
| • Ensure that the supply air temperature alarm threshold is set below the reheat |
| and cool setpoints. |
| • Ensure that the reheat mode is enabled. |
| • Ensure that the reheat mode is not disabled because of an active |
| input mapped to nonessential lockout. |
| • Verify that there is proper airflow through the Module (check the pressure |
| drop across the evaporator coil). |
|
|
System Comm Lost | • Check that the System is receiving power. |
| • Check the external CAN bus connections. |
| • Check the System ID DIP switch settings of every Main Module in the |
| Group. Each Main Module must have a unique address. See the Installation |
| Manual for the correct DIP switch settings. |
