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.
