1) Move actuator to the valve CLOSED position using
handwheel operation.
2) Using a flat screwdriver, depress the Drive Clutch Shaft
and rotate to “SET” position as shown on the switch
mechanism faceplate.
3) The CLS Adjustment Screw must now be rotated to
make the closed limit switch inside the switch mechanism.
The CLS Indicator Window will show one of four
possible symbols. Please refer to Figure 1 on page 7
for direction input.
4) Depending on where the mechanism is in the cycle, it
is possible that the switch will be approached from the
wrong direction, in which case it is necessary to move
through the limit and approach it from the correct
direction. This is done to avoid the need to wind through
the whole mechanism to reach the limit position. The
correct direction to approach the limit is shown by the
arrow next to the Adjustment Screw input.
5) Perform two checks to confirm the CLOSED limit position
switch has been made correctly.
a. The feel of the Adjustment Screw will noticeably
change providing more mechanical resistance at the
switching point of the contact.
b. Confirm the switch has been made by checking the
CLOSED limit indicator is illuminated on the Atronik.
6) Using a flat screwdriver, depress the Drive Clutch Shaft
and rotate to “RUN” position as shown on the switch
mechanism faceplate.
7) Rotate the CLS and OLS Adjustment Screws a small
amount in both directions to re-engage the mechanism
drive. A click will be heard as the drive drops back into
engagement and the adjustment screws will no longer
move in either direction.
Step 7 must be done or the limit will be lost when the
actuator is moved.
