10.8.15 Condenser Pressure Sensor Fault
This alarm indicates that the condensing pressure transducer is not operating properly.
Circuit status is Off.
The circuit is stopped.
Bell icon is moving on controller’s
display.
String in the alarm list:
CxCmp1 CondPressSen
String in the alarm log:
CxCmp1 CondPressSen
String in the alarm snapshot
CxCmp1 CondPressSen
Check for sensor integrity. Check
correct sensors operation
according information about mVolt
(mV) range related to pressure
values in kPa.
Check if sensor is shorted with a
resistance measurement.
Sensor is not properly connected
(open).
Check for correct installation of the
sensor on refrigerant circuit pipe. The
transducer must be able to sense the
pressure through the valve’s needle.
Check for absence of water or
humidity on sensor electrical
contacts.
Check for correct plug-in of the
electrical connectors.
Check for correct sensors wiring also
according electrical scheme.
10.8.16 Motor Temperature Sensor Fault
This alarm is generated to indicate that the sensor is not reading properly.
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 OffMtrTempSen
String in the alarm log:
CxCmp1 OffMtrTempSen
String in the alarm snapshot
CxCmp1 OffMtrTempSen
Check for sensor integrity.
Check correct sensors operation
according information acceptable
resistance range related to
temperature values.
Check if sensor is shorted with a
resistance measurement.
Sensor is not good connected (open).
Check for absence of water or
humidity on sensor electrical
contacts.
Check for correct plug-in of the
electrical connectors.
Check for correct sensors wiring also
according with electrical scheme.
