Mounting Instructions

Mount the PCV by sliding the actuator U-bolt over the damper
shaft. The back end of the PCV is secured by installing the
white plastic keeper (tied to the actuator motor with an elastic
band) with two sheet metal screws. This keeps the PCV from
moving when the actuator is turning, but still allows it to "float"
to avoid binding on the shaft if the controller were screwed
firmly in place.
Rotate the damper shaft all the way in one direction (either
clockwise or counter-clockwise) and then depress the gray
pivot clutch on the actuator, located directly below the green
terminal block, to unlock the actuator, and rotate it all the way
in the same direction the shaft was rotated in.
Tighten the nuts on the U-bolt clamp and secure the actuator
to the damper shaft.
Depress the clutch again and verify the actuator and shaft can
rotate through the full 90° range of motion.
NOTE: It does not matter if you choose clockwise or
counter-clockwise to rotate the shaft and actuator
before tightening the nuts. The PCV will calibrate on
power up. All that matters is that the damper shaft and
actuator have the full 90° range of motion.
Connect any of the controller's outputs as required.
NOTE: When the output loads require a switched HOT or
COMMON 24VAC signal. Use the jumper near the FAN output
to select HOT or COMMON outputs.
Power the PCV using 24VAC, the secondary 24VAC common
of the transformer must be earth grounded, or power with
Price PPM power module by plugging the supplied cables into
the RJ-12 power jacks.
