Maintenance
No routine maintenance is required. The motors
are permanently lubricated and all internal gear-
train components are oil-impregnated. Careful
installation will also ensure long term reliability and
performance.
Adjustments
The actuator is factory-set with the
OPERATE
selector switch in the clockwise
CW
position, and
the actuator will rotate clockwise with a 2–10 VDC
increasing control signal.
CAUTION
Do not press the gear disengagement button when
the actuator is powered, under load, or driven
against the end stops. Balance the load and remove
power to the actuator BEFORE pressing the button.
For Clockwise Rotation
1. Leave the
OPERATE
selector switch in the
CW
position.
2. Depress the gear disengagement button
and rotate the damper drive hub fully
counterclockwise to the
90
mark.
3. Determine what position the damper or valve
should be at 2 VDC input.
4. Position the damper or valve linkage to the full
open or close position as determined in step 3.
This ensures that as voltage increases and the
actuator rotates in the clockwise direction, the
damper or valve rotates in the proper direction.
5. Secure the actuator.
For Counterclockwise Rotation
1. Set the
OPERATE
selector switch in the
CCW
position.
2. Depress the gear disengagement button and
rotate the damper drive hub fully clockwise to the
0
mark.
3. Determine what position the damper or valve
should be at 2 VDC input.
4. Position the damper or valve linkage to the full
open or close position as determined in step 3.
This ensures that as voltage increases and the
actuator rotates in the counterclockwise direction,
the damper or valve rotates in the proper
direction.
5. Secure the actuator.
Limit Min./Max. Travel with End Stop Screws
1. Loosen the minimum and maximum stop screws
one-half turn.
2. Slide the screws to the desired positions.
3. Tighten the stop screws (9 in-lbs. maximum).
Fail-Safe Function (MEP-5372 only)
The fail-safe switch on the MEP-5372 is factory-set
in the
Off
position. Select either
CW
or
CCW
on the
three-position switch to choose the direction the
actuator will rotate when power is lost.
