5.5 Compressor Motor Current Calibration
fig.120: Motor Current Calibration Pad
1.
In the Main Tab of the Compressor Control Screen
Ensure that the compressor motor is stopped and the motor current reading is stable.
2. Start the compressor.
3. Load the compressor to 100% if possible. The compressor must load to at least 50% to complete the calibra-
tion process.
4. Touch the
Hold button to maintain a constant capacity slide position.
5. Put the hand-held clamp of an amp probe around one of the compressor's motor leads or refer to the motor
amp display on the starter if applicable.
6. In the Sensors Tab of the Configuration Screen
Touch the value in the measured column of the Motor Current row in the table to bring up the calibration pad
and enter the measured motor current in the text box located above the Save Current Offset button.
7. Touch the
Save Current Offset button.
8.
In the Main Tab of the Compressor Control Screen
Unload the compressor to 0%.
9. Stop the compressor.
10. In the Sensors Tab of the Configuration Screen
Touch the value in the measured column of the Motor Current row in the table to bring up the calibration pad
and touch the Save Low Offset button.
5.6 Capacity Slide Sensor Calibration
These steps only need to be performed if the original slide valve position sensor is being replaced. Once the
sensor itself has been calibrated as described below, the input will need to be calibrated separately as described
in Section 5.3, Page 227.
5.6.1 Capacity Slide Calibration with External Oil Pump
1. Ensure that the control panel is in
Service Mode and the compressor is Stopped .
