Disassembly
1. Remove the valve from service.
2. Shut off the delivery of air.
3. Disconnect the electrical supply and lock out all
power
4. Unscrew the single-piece clear top (Figure 41) and
remove it.
5. To remove the solenoids, unscrew them from the
base, being careful with the wires.
6. To remove the Set & Forget switch, (Figure 41),
disconnect wires then remove locking screws (Figure
41)
7. Grasp the switch housing firmly and pull the switch
up out of the sensor mount.
8. To disassemble the Proximity or Micro Switch
mounts, disconnect the wires, then unscrew the
round-head screws holding the switch to the switch
blocks. See “W-Series 2-Piece Control Module with
Proximity or Micro Switches” on page 38, item 37.
Assembly
Install in reverse order as described above.
1. Referring to Figure 42, insert the Set & Forget switch
over the indicator stem and target, into the sensor
mount, aligning the switch to the desired location,
typically with the LED’s facing outward. Ensure a
tight fit.
2. Install the locking screws (Figure 41) at three
locations and hand-tighten. Be careful not to over-
tighten the locking screws.
3. To assemble the Proximity or Micro Switch mounts,
install the switch blocks with cap screws (See Figure
52, page 34, item A) onto the mounting bracket.
4. Connect the wiring.
5. To install solenoids, first check that the o-ring at the
solenoid base is in place. Thread the solenoid into the
module base until metal-to metal contact is made. Do
not over-tighten or strip the threads.
6. Connect the wiring.
7. Ensure that the cover top o-ring (Figure 41) is in
place. Replace if damaged.
8. Screw the single-piece, clear top (Figure 41) onto the
module base until the top bottoms out, being careful
not to crimp the wiring.

“Stem-lowered” is understood to be when the valve stem
is fully extended out from the actuator.
Function and Features
The Set & Forget rising stem valve sensor is a continuous
absolute linear measurement system with a measuring
stroke of 3.15" (80mm). The sensor is used for position
feedback for rising stem valves. For position detection,
three programmable switch points can be freely selected in
the measuring range. The position is signaled visually by 3
LED’s.
CAUTION:
Only an authorized electrician
should disconnect power.
