ADJUSTMENT PROCEDURE
A. Operate actuator to full closed position. Set screws hold cams in place on the shaft. For manual cams, grasp cam
on knurled segment of cam surface and simply rotate cam to get correct actuation point. Clicks indicate incremental
adjustments. Applying pressure on cam in direction of protruding actuation segment of cam surface, and rotating,
eliminates incremental adjustments. Stop rotating and release pressure on cam when at proper actuation point. This
allows engagement of cam to spline. Check circuit to verify contact at proper point. Repeat the cam adjustment
steps as necessary. Lock manual cam on spline with set screw provided for additional security.
B. Operate actuator to opposite extreme (full Open), and adjust cams to suit.
C. Screw on cover and tighten against o-ring seal until cover does not turn.
