The adjustable stops are needed when there is no damper stop
or if you want the damper to stop rotating before it reaches its
stops. The non-spring return actuators can be indefinitely
stalled in any position without harm.
1. Loosen the two end stops with a No. 2 Phillips head screwdriver
being careful not to unscrew the captive nut under the slot.
2. Move the stops (in 2.5° steps) to the desired position and re-
tighten the screws.
Non-spring return actuators have a reversing switch on the
cover. Switch position indicates start point. For the non-spring
return, with the switch in position 1, the actuator rotates clock-
wise with an decrease in voltage or current. With the switch in
position 0, the actuator rotates counterclockwise with an
decrease in voltage or current.
The non-spring return rotates clockwise when the switch is in the
1 position and power is applied to wire #2. When power is applied
to wire #3 the actuator rotates counter clockwise.
Rotating the switch to 0 reverses the control logic.
During checkout, the switch position can be temporarily
reversed and the actuator will reverse its direction. This allows
the technician a fast and easy way to check the actuator
operation without having to switch wires or change settings on
the thermostat.
When the check-out is complete, make sure
the switch is placed back to its original position.
The non-spring return actuators have a black, “manual override
button” located on the top of the housing. Press this button and
the gear train is disengaged so the damper shaft can be moved
manually. Release the button and the gear train is re-engaged.
Use the manual override to test the installation without
power. For tight shut-off the damper should close with
5° of actuator stroke left.
