Operation Manual
Solution
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.
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.
Notes
Solution
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.
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.
