2. Loosen the setscrews on the sides of the transducer and turn the device so the small cover is readily visible.
An inspection mirror may be used in lieu of rotating the transducer.
3. Remove the small round cover from the transducer.
4. Before proceeding the transducer must have been powered for at least one minute.
5. The red LED should be flashing at about a ½ second rate if the indicator is functional. Ignore any green LED
activity until the calibration is complete.
6. Initiate Oil Pump Test by touching the OIL PUMP button.
7. Touch the UNLOAD button and wait about 90 seconds for the slide valve to fully unload. Smaller machines
may not require the full 90 seconds to unload.
8. The calibration button on the transducer is positioned between the two LEDs. Push and hold the calibration
button for five seconds, both LEDs should be off.
9. Press the pushbutton one time and release it. The red LED will now turn On , and remain On , for approxi-
mately 3 seconds while the zero calibration point is stored. DO NOT move the slide valve until the red LED
turns off.
10. Touch the LOAD button and wait about 90 seconds for the slide valve to fully load. Smaller machines may
not require the full 90 seconds to load.

This process must be completed quickly because the indicator will abandon the calibration after a period
of time. Please note the red LED will flash approximately ¼ second every 5 seconds indicating the indi-
cator is active and that the calibration has not been fully completed.
11. Once the compressor is fully loaded, push the calibration button twice, and the red LED will flash rapidly for
approximately 3 seconds. Do not attempt to move slide valve until red LED turns Off . When the red LED
stops flashing the loaded position is set.
12. At this time the sensor will have an output of 20 mA. This can be verified on the Operating Data screen.
13. UNLOAD and LOAD the machine to confirm calibration. Refer to the Compressor Capacity on the Operating
Data display. It should track the slide valve between 4 mA and 20 mA.
14. Exit oil pump test by touching the OIL PUMP button.
15. Reinstall the cover.
16. If the transducer was rotated, restore it to the original orientation and tighten the setscrews.
17. Return load/unload needle valves to their original positions to ensure proper slide valve movement.
5.6.2 Capacity Slide Calibration without External Oil Pump
1. Ensure that the control panel is in
Service mode and the compressor is Stopped .
2. Loosen the setscrews on the sides of the transducer and turn the device so the small cover is readily visible.
An inspection mirror may be used in lieu of rotating the transducer.
3. Remove the small round cover from the transducer.
4. Before proceeding the transducer must have been powered for at least one minute.
5. The red LED should be flashing at about a ½ second rate if the indicator is functional. Ignore any green LED
activity until the calibration is complete.
