Linear Adapter

2. The PS2 input shaft is shown in above, right. It extends from the bottom of the positioner and is

flat on one side. Place the linear adapter on the PS2 input shaft so the setscrew can be tightened

against the flat on the input shaft. Tighten the setscrew securely.

Install Feedback Lever on the Linear Adapter

1. Secure feedback arm to linear adapter with the supplied split lockwasher and nut. See Figure 4.

2. Be sure spring clip wire is facing actuator during this assembly. Thus feedback pin will contact

spring clip before the pin goes through the feedback arm slot.

Install the Feedback Pin to the Actuator/Valve Stem Coupling

1. Using table 1 on page 3, use the appropriate feedback pin as per actuator model number.

2. Install 3/8" nut onto feedback pin. Thread hex nut onto the feedback pin up to the unthreaded

portion of the pin.

3. Screw the pin into the hole in the actuator coupling. Do not tighten the pin or nut at this time.
