Troubleshooting
Compressor Fail
Description of Fault
A CATALYST Compressor Failure Alarm is generated when the CATALYST commands the unit into full mechanical cooling and the Total Unit Power does not register a corresponding rise in amps that would indicate that the compressors are energized.
A CATALYST Compressor Failure Alarm will automatically reset when the compressors are commanded to energize and the Total Unit Power registers a corresponding rise in amps.
Possible Causes
A CATALYST Compressor Fail is typically caused by:
-
Compressors are off on a unitary safety.
-
Faulty or loose control wiring.
-
Failed contactor.
-
Failed compressors.
Troubleshooting
eIQ Platform
-
On the eIQ Platform, navigate to the Settings page of the unit and locate the Soft Switch.
-
Turn the Service switch to the off position.
-
Navigate to the status page and verify the unit is not outputting any cooling commands.
-
Go back to the settings page and set the Soft Switch to the Cool 2 Fan 100% position.
-
Navigate to the Status page of unit and verify that full cooling is commanded on and the Total Unit Power indicates at least 75% consumption
-
If the total unit power rises above 75% continue to monitor the unit for 10-15 minutes to verify that the compressors continue to run and do not trip on any unitary safeties.
-
If the total unit power does not rise above 75% a technician will need to investigate the equipment to resolve the issue.
-
Site
-
Access the CATALYST Service Switch typically located in the controls section of the Unit.
-
Set the CATALYST Service Switch to the Unit OFF position and verify the fan and compressors are disengaged.
-
Set the CATALYST Service Switch to the Cool 2 Fan 100% position and verify the first stage compressor has energized.
-
If the any compressors fail to energize:
-
Verify that you have 24 volts AC on Y1 (Yellow wire from the CATALYST green 8 conductor) and Y2 (Blue wire from the CATALYST green 8 conductor) on the unit’s low voltage terminal.
-
If there is voltage on the Y1, and Y2 wires from the CATALYST green 8-conductor, then the compressors are not functioning due to a mechanical deficiency with the unit. Continue standard mechanical troubleshooting to resolve the issue.
-
If there is no voltage on the Y1, and Y2 wires from the CATALYST green 8-conductor, then contact Transformative Wave for additional troubleshooting support.
