Coupled Actuators (DCA) are used within heating, ventilating,

and air-conditioning (HVAC) systems. They can drive a variety

of quarter-turn, final control elements requiring spring return

fail-safe operation.

Applications include:

• Volume control dampers, mounted directly to the drive

shaft or remotely (with the use of accessory hardware).

• Quarter-turn rotary valves, such as ball or butterfly valves

mounted directly to the drive shaft.

• Linear stroke globe or cage valves mounted with linkages

to provide linear actuation.

• Available with cable on select models

NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS TYPICAL SPECIFICATION CAUTION Spring return actuators shall be direct coupled type requiring neither crankarm nor linkage and be capable of direct mounting to a jackshaft of up to 5/8 in. diameter. The actuator shall connect to the shaft using a removable output hub with a self-centering shaft coupling. This coupling shall provide concentric mounting and include an integral adjustable range-stop mechanism.
PAGE 4
3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS If the coupling must be moved from one side of the actuator to the other, reverse the spring return direction and flip the actuator. Follow these instructions (see Fig. 3): 1. Remove the retainer clip from the shaft coupling and set it aside for later use. 2. Remove shaft coupling from one side of the actuator. 3. Replace the shaft coupling on the opposite side of the actuator aligning it based on the stroke labeling. 4.

3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS CAUTION Actuator Damage Hazard. Using actuator as shaft bearing causes device damage. Use actuator only to supply rotational torque. Avoid any side loads to actuator output coupling bearings. CAUTION Equipment Damage Hazard. Can damage the motor beyond repair. Never turn the motor shaft by hand or with a wrench. Forcibly turning the motor shaft can damage the gear train.

3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS NOTE: This cover can be removed before or after mounting actuator to the damper shaft or valve linkage. In order to wire the device, the access cover must be removed as follows: 1. Remove the screw from the center of the cover, set the screw aside. 2. Pull the cover along the long axis of the actuator. 3. If the actuator is not yet mounted, set it aside. 4. Remove conduit dust covers. 5. Thread wire through conduit holes. 6.
