Mounting
Damper Actuator Sizing
Correct sizing of the actuator is necessary for proper control of dampers. The area of damper that can be controlled by a given actuator is dependent upon the quality of the damper, the pressure drop across the damper in the closed position, and the velocity of the air flow through the damper. To obtain actual damper torque requirements, contact the damper manufacturer.
Damper Shaft Sizing
Use the “Long Damper Shaft” mounting instructions if the damper shaft is at least 4-5/8"
(117 mm) long.
Use the “Short Damper Shaft” mounting instructions if the damper shaft is shorter than
4-5/8" or the area around the damper shaft is too narrow to allow standard mounting, as
described in the “Long Damper Shaft” mounting section. See Figure-5 for minimum shaft
length.
Min. 4-5/8" (117 mm)
Figure-5 Long Damper Shaft Dimensions.
Caution: The MF50-E2301 actuator is not designed to be used on aluminum damper shafts, solid steel shafts smaller than 1/2" diameter round or 1/2" square, or hollow steel shafts smaller than 3/4" round. The actuator can produce up to 450 in-lbs (51 N-m) maximum stall torque, which could result in the actuator snapping off an aluminum damper
shaft or an improperly sized steel damper shaft. Refer to Table-2 for nominal damper shaft
sizes.

CHECKOUT
This procedure is for checking out a normally closed actuator that is typically mounted unpowered. It is possible to mount the actuator with power applied for special applications.
After the entire system has been installed and the actuator has been powered up, the following check can be made for proper system operation. Check for correct operation of the damper while the actuator is being stroked.
1. Apply power to the actuator and control system.
2. Set the switch/controller to cause the actuator to drive open (usually, White wire to 24H).
3. Check to see that the actuator travels to the full-open position.
4. Set the switch/controller to cause the actuator to drive closed (usually, Red wire to 24H).
5. Check to see that the actuator travels to the fully closed position.
Note: If anticipated damper operation does not occur, verify the Long Damper Shaft or
Short Damper Shaft mounting procedures. Also, verify that the controller has the proper action (direct or reverse) to match the damper required operation.
THEORY OF OPERATION
The actuator is, by means of dual mounting clamps, directly mounted onto the damper shaft.
The anti-rotation bracket supplied with the actuator will prevent lateral movement of the actuator. The damper actuator is not provided with and does not require any limiting switches, but is electronically protected against overloading.
The angle or rotation is electronically limited to 93° ±1°. When reaching the damper or actuator end position, the motor stops automatically. The position of the actuator is indicated by means of scale reading 0 to 95°.
MAINTENANCE
Regular maintenance of the total system is recommended to assure sustained optimum performance. The MF50-E2301 actuator is maintenance free.
FIELD REPAIR
None. Replace with functional actuator.
