Application
The CSP-4702 mounts directly to 1/4- to 5/8-inch (6 to
16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm)
square shafts.
1. Ensure the damper can move freely through its
entire range of motion, and fix any binding before
installing the actuator. Turn the damper blade to
its fully closed position.
2. Press (to the right) and hold the gear disengage-
ment lever (see Illustration 1), rotate the actuator
to the fully closed position, and release the lever.
NOTE: Depending on the damper-seal design,

3. Align the actuator and slide it onto the shaft.
4. Leaving a small gap between the actuator and
mounting surface to prevent any binding, finger-
tighten the nuts on the V-bolt.
5. Insert the provided (HMO-4002) non-rotation
bracket into the slot at the base of the actuator
and secure the non-rotation bracket with two #8
or #10 self-tapping screws.
6. Evenly tighten the V-bolt nuts (30–35 in-lb.).
7. If desired, use a 7/64-inch hex key wrench to
loosen and position the end-stop screw.
NOTE: The two holes at the top of the actuator
are NOT for use in direct-coupled
applications. (They are for remote
mounting, such as with the optional HLO-
4001 Crank Arm Kit.)

Questions and answers
What drives the actuator to close. If there's an active call to open the actuator. When that signal is no longer there, what drives it to close.
The KMC Controls CSP-4702 actuator closes after an active call to open is removed because the Close LED illuminates (solid red) when the actuator is closing. When the actuator reaches the end of rotation or the mechanical stop, the LED may stay illuminated briefly if the called-for condition remains unsatisfied.

@Mr. Anderson
Thank you Mr. Anderson. That's what I thought but for some reason once the call signal was disengaged it would not close. Thank you again!
