6. Select the Min or Max position of the slide valve to
be calibrated.
NOTE
When the increase and decrease arrow buttons do
not correspond to the increase and decrease shaft
rotations, swap the blue and brown wires of the
“power cable”. This will reverse the rotation of the
actuator/command shaft.
7. Press increase or decrease arrows to move the slide
valve and check for the correct rotation.
NOTE
When the actuator is in calibration mode, it outputs
0V when the actuator is running and 5V when it
is still. The actuator voltage will fl uctuate during
calibration. After the actuator has been calibrated, 0V
output will correspond to the minimum position and
5V to the maximum position.
8. Quickly press and release the blue push button on
the actuator one time. This places the actuator in
calibration mode. The red LED will begin fl ashing
rapidly.
CAUTION
DO NOT CONTINUE TO ENERGIZE THE ACTUATO
R
MOTOR AFTER THE SLIDE HAS REACHED THE
MECHANICAL STOP. Doing so may cause mechanical
damage to the motor or shear the motor shaft key.
When the slide has reached the mechanical stop
position, press the button in the center of the photo-
chopper to release the brake, and thereby release the
tension on the actuator motor.
NOTE
The “Slide calibration” screen displays twice the
actuator output voltage. Both these values (% volume
and % capacity) are meaningless until calibration has
been completed.
9. Use the down arrow button to drive the slide valve
to its minimum “mechanical stop” position. Do not
continue to run the actuator in this direction after
the slide valve has reached the stop. Doing so may
cause damage to the actuator or the slide valve.
10. Press down and release on the photo-chopper shaft
to disengage the brake, releasing tension from the
motor mount, see Figure 6-9.
11. Use the up arrow button to pulse the actuator to
where the slide is just off of the mechanical stop
and there is no tension on the motor shaft.
12. Quickly press and release the blue button on the
actuator again. The red LED will now fl ash at a slow-
er rate indicating that the minimum slide valve po-
sition (zero position) has been set.
13. Use the up arrow button to drive the slide to its
maximum “mechanical stop” position. Do not
continue to run the actuator in this direction after
the slide valve has reached the stop. Doing so may
cause damage to the actuator or the slide valve.
14. Press down and release on the photo-chopper shaft
to disengage the brake, releasing tension from the
motor mount.
15. Use the down arrow button to pulse the actuator to
where the slide is just off of its mechanical stop and
there is no tension on the motor shaft.
