PAGES 6-7: SENSOR CALIBRATION
Figure 12 : Sensor Calibration
Sensor calibration can only take place when the compressor is stopped.
There should be no pressure on a sensor when it is calibrated. Calibration
only needs to take place after a sensor is replaced, the controller is replaced,
or the operator suspects the sensor reading is in error. Calibrate a sensor by
selecting the checkbox beside the sensor name.
Each of the sensors listed below can be calibrated:
• Inlet Vacuum (1AVPT)
• Sump Pressure (3APT)
• Package Discharge Pressure (4APT)
• Coolant Filter Inlet Pressure (5CPT)
• Coolant Filter Outlet Pressure (6CPT)
• Remote Pressure (10APT) – Only on compressors with the remote sensor
option
• Interstage Pressure (2APT) – Only on 2-stage compressors
• After-cooler Discharge Pressure (7APT) – Only on compressors with
integrated dryer
Please note that if a sensor is currently reading a value that is +/- 10% of
its range from zero, the sensor will not be able to be calibrated. Please
make sure the sensor is being exposed to atmosphere before attempting
calibration.
