Calibrate Slide Valve
This screen is shown if it applies to the compressor model
(Reference Compressor Model Differences). This screen
shows a pictorial representation of a Slide Valve and Slide
Stop. Reference the picture of the Calibrate Slide Stop
screen. The Slide Valve and Slide Stop status information,
the Motor Amps reading, and the Suction, Discharge, and
Oil Pressure readings are shown here for quick reference.
The screen heading and the high-lighted heading in the
table, both depict what is presently selected to be
calibrated. The minimum Slide Valve value represents the
furthest position the Slide Valve can be unloaded to and is
always set at 0%. The maximum Slide Valve value
represents the furthest position Slide Valve can be loaded
to and is always set at 100%. The current reading is the
reading that changes when increasing or decreasing the
Slide Valve. An invalid current reading is indicative of the
need to calibrate. The volts reading corresponds to the
metered voltage that is measured when the Slide Valve is
at the displayed position. The screen keys are positioned
in the order they should be used. The following keys are
provided:
[Decrease Slide Stop] - The initial selection of this key
will cause the Slide Stop to continuously decrease.
Selecting this key again will stop the Slide Stop at the
current position. For proper calibration of the Slide
Valve, the Slide Stop should be decreased to the
minimum point.
[Unload Slide Valve] - The initial selection of this key
will cause the Slide Valve to continuously unload.
Selecting this key again will stop the Slide Valve at the
current position.
[Set Minimum Point] - This key should be selected
when the Slide Valve is at the furthermost unload
position or lowest voltage reading. The minimum Slide
Valve value of 0% will then be set as the current Slide
Valve value.
[Load Slide Valve] - The initial selection of this key will
cause the Slide Valve to continuously load. Selecting
this key again will stop the Slide Valve at the current
position.
[Set Maximum Point] - This key should be selected
when the Slide Valve is at the furthermost load position
or highest voltage reading. The maximum Slide Valve
value of 100% will then be set as the current Slide
Valve value.
[Slide Stop Calibration] - Shows the Slide Stop
Calibration screen.
Note: If a force unload, or a stop load condition is present
as shown on the Operating Status screen, this will
interfere with the proper calibration.
