Application
The P…A GR feedback potentiometers are used with TLM,
TNM, TAM, and TGM actuators to provide a resistive signal
which varies with damper position.
The P…A GR units are applied with commercial proportional
temperature controllers to provide feedback of the damper
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 GR feedback potentiometers are mounted onto the
direct coupled actuator. The switches are modular units that
mount directly onto TLM, TNM, TAM, and TGM type actuators
and are locked into place by guiding grooves on the sides of
the actuator.
A driver disk is attached to the actuator clamp and offers
direct transmission of the actuator position to the micro switch
cams.
Mounting Instructions
1. Remove position indicator from actuator.
2. Press down the manual override button and rotate the
actuator fully counter-clockwise.
3. Turn the driver disk on the potentiometer fully
counterclockwise.
4. Slide potentiometer onto the actuator using the actuator
guiding grooves on the sides of the actuator.
5. Check for correct mating of the driver disk to the
universal clamp.
