Feedback Potentiometer P...A

For the non-spring return direct-coupled actuators

Application

The P…A feedback potentiometers are used with LR and AR actuators

to provide a resistive signal which varies with valve position.

The P…A units are applied with commercial proportional temperature

controllers to provide feedback of the valve position, or with electric or

electronic meters to provide position indication. The signal can also be

used as a positioner for parallel operation of multiple actuators.

Operation

The P…A feedback potentiometers are mounted onto the direct coupled

actuator. The switches are modular units that mount directly onto LR and

AR type actuators and are locked into place by guiding grooves on the

sides of the actuator.

A driver disk is attached to the actuator handle and offers direct

transmission of the actuator position to the micro switch cams.

Wiring Diagram

Mounting Instructions

1. Press down the manual override button and rotate the

actuator fully counter clockwise.

2. Place the switch/potentiometer adaptor onto the hex shaft of the

handle which is in the center of the valve/actuator coupling.

3. Slide switch onto the actuator using the actuator guiding grooves

on the sides of the actuator.

4. Check for correct mating of the adaptor to the switch.

5. Adjust switch dials as necessary.
