• Calibrated pressure gauge (0 to 30 psi)
• 1/16” flexible tubing
• Barbed Tee (Clippard Minimatic part number T22-2 or equivalent)
• 3/32” Allen wrench
• 3/8” open-end wrench
WARNING: Observe precautions for handling electrostatically sensitive devices.
1. Make sure the valve is bypassed or in a safe condition.
2. Remove the main cover.
3. Remove the two keypad retaining screws. Carefully pull the keypad away from the main PCB board. Unplug
the keypad ribbon cable from the main PCB board and remove the keypad.
4. Remove the main PCB assembly by following the instructions in section 14.15 of this manual.
5. It will be necessary to plug the actuator pressure sensor ports. Make sure the pressure sensor o-rings are still
in place. Install plug plate (Part Number 185162.601.003) below the pressure sensor board stiffener (item 9)
and tighten the pressure sensor board stiffener screws (item 8).
6. Remove the 1/16” flexible tubing from the barbed fitting on the side of the driver module.
7. Obtain a barbed tee and two pieces of 1/16” flexible tubing a few inches in length each.
8. Position the barbed tee between the internal regulator and the driver module by connecting the 1/16” flexible
tubing, found in the positioner, to one side of the barbed tee. Using one of the new flexible tubing pieces,
connect the barbed tee to the barbed fitting on the side of the driver module. Connect the remaining port on
the barbed tee to a 0 to 30 psig pressure gauge.

9. Reconnect the air supply to the positioner and read the internal regulator pressure on the 0 to 30 psig gauge.
The internal pressure should be set to 21.5 +/- .2 psig. If adjustment is needed, loosen the set screw retaining
nut on the top of the regulator using the 3/8” open-end wrench. Then adjust the regulator pressure by turning
the set screw on the top of the regulator with the 3/32” Allen wrench.
10. Once the regulator pressure is set, tighten the set screw retaining nut on the top of the regulator, remove the
air supply to the positioner, remove the barbed tee, and reconnect the flexible tubing from the regulator to the
barbed fitting on the side of the driver module.
