7. Quickly press and release the blue button on the ac-
tuator again. The red LED will now ash at a slower
rate, indicating that the minimum slide valve position
(zero position) has been set.
8. Use the increase button on the calibration tool to
drive the slide to its maximum “mechanical stop” po-
sition. Release the increase button when the slowing
of the motor rotation and a winding sound from the
actuator motor is noted.
9. Press and hold down on the photo-chopper shaft to
disengage the brake slowly, releasing tension from
the motor mount. Use the decrease button to pulse
the actuator to where the slide is just off of its me-
chanical stop and there is no tension on the motor
shaft.
10. Quickly press and release the blue button on the ac-
tuator one more time. The red LED will stop ash-
ing. The actuator is now calibrated and knows the
minimum and maximum positions of the slide valve
it controls.
11. Disconnect the calibration tool’s turck from the ac-
tuator, and connect the motor control cable on the
actuator (connector J2).
