5.3 Capacity Slide Position Calibration
Touching the cell associated with the Measured value of the Capacity Slide Position will bring up the calibration
pad shown below.
fig.117: Capacity Slide Calibration Pad
The buttons displayed along the bottom row of the sub screen are used to calibrate these sensors. The functions
of the buttons are:
1. LOAD
Touching this button will energize the solenoids to load the sensor to 100 %. Touching it a second time will
de-energize the solenoids. While the solenoids are energized the indicator displayed on the right edge of the
button will be illuminated green.
2. UNLOAD
Touching this button will energize the solenoids to unload the sensor to 0 %. Touching it a second time will
de-energize the solenoids. While the solenoids are energized the indicator displayed on the right edge of the
button will be illuminated green.
3. OIL PUMP
Touching this button will toggle the oil pump on or off.
4. AUTO CALIBRATE
Touching this button will cause the sensor to energize the solenoid to load fully. If no movement is detected,
a message will appear to inform the user that the auto calibration failed. Once the slide has loaded fully, the
current reading will be set as the maximum position and the slide will unload fully. The reading of the sensor
once it has fully unloading will be set as the minimum position.
5. Save Low Offset
Touching this button will save the current reading of the sensor as the capacity slide´s minimum position.
6. Save High Offset
Touching this button will save the current reading of the sensor as the capacity slide´s maximum position.
For new compressor packages, the required steps for calibrating a Capacity Slide Position sensor vary depend-
ing on whether or not the package is equipped with an external oil pump. Refer to Section 5.3.1, Page 228 for
compressors equipped with an external oil pump and Section 5.3.2, Page 228 for compressors without an exter-
nal oil pump.
Hint!
Step variable Vi compressors manufactured by Mycom, Frick or Kobe will require a different
procedure, which is detailed in Section 5.3.3, Page 230.
