ADJUSTMENT PROCEDURE
1. using wrench or power, rotate the actuator shaft to extreme clockwise position
for direct drive applications. For linear applications, operate actuator to full closed
position. All switches should change to their appropriate functions.
2. The cam can be relocated and repositioned by loosening the set screw. To adjust
manual cams grasp cam on knurled segment of cam surface. rotate cam clock-
wise or counterclockwise to obtain correct actuation point. Feeling or sound of
clicks indicates incremental adjustments. Applying pressure on cam in direction of
actuation segment of cam surface, and rotating, eliminates incremental adjust-
ments. Stop rotating and release pressure on the cam when it is at proper actua-
tion point; this allows engagement of cam to spline. Check circuit to verify contact
at proper point. rotate the shaft counterclockwise. repeat all steps above as nec-
essary. Lock cam on spine with set screw provided for additional security.
3. Operate actuator to extreme opposite position to verify correct operation of
switch(es). readjust as required.
4. replace OPen/CLOSeD indicator drum making sure incoming wires are tucked
in so as not to rub against the drum. replace cover window making sure it lines up
correctly with indicator to display the proper indication of valve position. replace
snap-on cover.
WIRING

all screws. (Sealed leads are provided from the factory on request).
