5. Adjust the microswitches. This step will
require air to apply to the actuator via fitting
(see fig. 16) . Loosen the screws holding the
microswitches to the microswitch bracket.
Push the microswitches as far from the shaft
as they will go transversely to the shaft and
snug the screws, but do not fully tighten. Test
the actuator and watch the actuator stem
go up and down. The actuation zone (as
shown in fig. 15) must depress the according
microswitch when the valve is open and
closed. Figure 15 shows the actuator stem
“up” or the valve open. Set the microswitch
such that the roller is in the center of the
actuation zone, the switch is not too far or
firmly depressed (thus risking damage to the
microswitch) and the microswitch is parallel
to the shaft. Repeat the process for the
valve-closed microswitch (lower).
