5.5.3 High Compressor Vfd Temperature fault
This alarm is generated to indicate that the Vfd temperature is too high to allow the compressor to run.
Symptom
Cause
Solution
Circuit status is Off.
The circuit is switched off with the
normal shutdown procedure.
Bell icon is moving on controller’s
display.
String in the alarm list:
CxCmp1 VfdOverTemp
String in the alarm log:
CxCmp1 VfdOverTemp
String in the alarm snapshot
CxCmp1 VfdOverTemp
Cooling solenoid valve is not
operating properly.
Check electrical connection of the
solenoid valve.
Check refrigerant charge. Low
refrigerant charge can cause
overheating of the Vfd electronic.
Check for obstructions in the pipe.
Vfd Heater not properly connected.
Check if Vfd heater is switched off
when the Vfd temperature increases.
