MS8103, MS4103, MS7503, MS7403, MS8105, MS4105,

MS7505, MS7405 Spring Return Direct Coupled Actuators

(DCA) are used within heating, ventilating, and air-condition-

ing (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.

S03, S05 SERIES SPRING RETURN DIRECT COUPLED ACTUATORS Selecting Actuator Control Signal 4. 5. Selections are made using a dial that appears on both the front and back of the actuator (see Fig. 4). Install the shaft coupling at this position. Replace the retainer clip on the shaft coupling using the groove of the coupling. To select the control signal simply turn the mode selection dial to the desired mode (as indicated on the device label) without exceeding range indicators.
