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
theactuatorwillrotateclockwisewitha2–10VDC
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. Depressthegeardisengagementbuon
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. Depressthegeardisengagementbuonand
rotate the damper drive hub fully clockwise to the
0mark.
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. Tightenthestopscrews(9in-lbs.maximum).
Fail-Safe Function (MEP-5372 only)
Thefail-safeswitchontheMEP-5372isfactory-set
in the O position. Select either CW or CCW on the
three-position switch to choose the direction the
actuator will rotate when power is lost.
