The “Calibrate Slide Stop” screen is shown if it applies to
the compressor model (Reference “Compressor Model Dif-
ferences”). It shows a pictorial representation of a Slide
Valve and Slide Stop. The Slide Valve and Slide Stop status
information, the Motor Amps reading, and the Suction, Dis-
charge, and Oil Pressure readings are shown here for quick
reference. The same information of the Slide Valve and Slide
Stop status box, shown on the Operating Status display, is
also shown here for quick reference. The screen heading
and the highlighted heading in the table, both depict what
is presently selected to be calibrated. The Slide Stop should
be calibrated prior to calibrating the Slide Valve. Calibrating
the slide stop requires setting the minimum and maximum
Slide Stop. The minimum Slide Stop value represents the
furthermost position the Slide Stop can be decreased to.
The maximum Slide Stop value represents the furthermost
position the Slide Stop can be increased to. The current
reading is the reading that changes when increasing or
decreasing the Slide Stop. An invalid reading is indicative
of the need to calibrate. The volts reading corresponds to
the metered voltage that is measured when the Slide Stop
is at the displayed position. The screen keys are positioned
in the order they should be used. ( The RWB model 355 and
283 are exceptions to this sequence order. With these the
[Decrease Slide Stop] should precede the [Unload Slide
Valve] ). The following keys are provided:
[Unload Slide Valve] - The initial selection of this key
will cause the Slide Valve position to continuously un-
load. Selecting this key again will stop the Slide Valve
at the current position. The slide valve position should
be unloaded until it does not interfere with decreasing
the Slide Stop.
[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. To decrease the Slide Stop to the
minimum point, it is necessary that the Slide Valve po-
sition be increased until the Slide Stop will no longer
decrease.
[Set Minimum Point] - This key should be selected
when the Slide Stop is at the minimum position or low-
est voltage reading. The minimum Slide Stop value of
2.2 will then be set as the current Slide Stop value.
[Increase Slide Stop] - The initial selection of this key
will cause the Slide Stop to continuously increase. Se-
lecting this key again will stop the Slide Stop at the
current position.
[Set Maximum Point] - This key should be selected
when the Slide Stop is at the maximum position or
highest voltage reading. The maximum Slide Stop value
of 5.0 will then be set as the current Slide Stop value.
[Slide Valve Calibration] - Shows the Slide Valve cali-
bration screen.

”Calibrate Slide Valve” SCREEN
This screen is shown if it applies to the compressor model
(Reference “Compressor Model Differences”). This screen
shows a pictorial representation of a sSlide 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.
