Mechanical Switches
(Continued)
Each switch is actuated by a rotating cam. To adjust a top switch, push the top cam down, rotate it to
the desired position, and release the cam so it engages into the new position on the spline. To adjust a
bottom switch, repeat the process with the bottom cam, but lift the cam upwards to rotate it to the
desired position. Each cam may be further fine-tuned between spline positions by turning the set screw
on the cam with a 1/16" hex driver. The set screw is limited to adjustment of no more than one full turn.
Proximity Switches
The two SPDT proximity switches each has a rating of 0.3 amp at 120 VAC, or 0.2 amp at 30 VDC. The
switch contacts are sealed for low-energy switching of solid-state signal circuits.
The top switch is factory set to trip as the valve reaches the closed or clockwise position, and the
bottom switch is factory set to trip as the valve reaches the open or counterclockwise position. The
internal wiring from the switches to the terminal strip is shown in Figure 2.
Each switch is actuated as the white stripe on its rotating cam aligns with the white stripe on the switch.
To adjust the top switch, push the top cam down, rotate it to the desired position, and release the cam
so it slides into the new position on the spline. To adjust the bottom switch, repeat the process with the
bottom cam, but lift the cam upwards to rotate it to the desired position.
