Installation Instructions For Replacement Of Optical Actuator
CAUTION: WHEN INSTALLING THE
OPTICAL SLIDE MOTOR, LOOSEN
LOCKING COLLAR BEFORE SLIDING
THE COLLAR DOWN THE SHAFT. DO
NOT USE A SCREWDRIVER TO PRY
LOCKING COLLAR INTO POSITION.
OVERVIEW
Calibration of an optical slide valve actuator is a
two step process that must be down for each actua-
tor installed on the compressor. The steps are as fol-
lows.
1. The actuator motor control module,
located inside the actuator housing, is
calibrated so that it knows the minimum
and maximum rotational positions of the
slide valve it controls. The calibrated act
uator will output 0 VDC at the minimum
position and 5 VDC at maximum position.
2. After the actuator motor control module has
been calibrated for 0-5 Volts, the controll
ing channel corresponding to the actuator
motor ( either the capacity or volume) has
to be calibrated. This instructs the Vission/
Vantage control panel to learn the rotational
0% position & rotation 100% position of
the slide valve travel.
Please Note:
Because there is an optical sensor on this motor, DO
NOT attempt to calibration in direct sunlight.
3. Before appling power to the Vission/Van
tage disconnect the gray and yellow cable.
4. Power the Vission/Vantage back on.
5. Refer to Calibration Procedure of
Optical Actuators (page 60-62).
