3. Verify that the compressor is physically fully unloaded. The GEA Omni™ will allow the compressor to
start if it has a slide valve reading less than 70 %. Otherwise, the slide valve mechanism must be
mechanically adjusted to less than 70 % to allow the compressor to be initially started.
4. Start the compressor and wait until the compressor is
Running
and oil pressure has been established.
5 Touch the
UNLOAD
button. Wait until the slide valve reaches the fully unloaded position, at which point
the value in the
Raw Signal
column should stabilize. The value that the signal will stabilize to is deter-
mined by the type of sensor being used.
6. Touch the
Save Low Offset
button. The corresponding slide valve position sensor output has been
recorded as the fully unloaded position.
7. Touch the
LOAD
button. Wait until the slide valve reaches the fully loaded position, at which point the
value in the
Raw Signal
column should stabilize. The value that the signal will stabilize to is determined
by the type of sensor being used.
8. Touch the
Save High Offset
button, the corresponding slide valve position sensor output has been
recorded as the fully loaded position.
9. Touch the
UNLOAD
button again. The compressor should fully unload and the indicated
Capacity Slide
Position
should track with it. Touch the
LOAD
button to fully load the compressor and observe the
Capacity Slide Position
.
10. If the
Capacity Slide Position
appears to track the
Raw Signal
and appears to track with the mechanical
indication (if equipped with this feature), calibration is complete.
11. Exit the calibration pad by touching the
X
button.
12. If desired, the compressor may be
Stopped
at this point.
