Application
TAC DuraDrive Direct Coupled Actuators are designed
to be used in both damper and valve control
applications. The following general instructions are for
damper applications, refer to the Applicable Literature
table for valve literature.
The MS40-717X series actuators are over the shaft
spring return actuators compatible with 2 to 10 Vdc or
1
4 to 20 mAdc
control signals.

- Page 9 Mounting Mount the TAC DuraDrive Actuator directly on the damper shaft in locations that clear the maximum dimensions of the actuator case and allow the actuator to be mounted flush to the surface of the terminal box and perpendicular to the damper shaft. Note: Some terminal boxes have sheet metal screw heads or other protrusions near the damper shaft.
- Page 10 Mounting the Actuator for Clockwise or Counterclockwise Dampers The zero (0) position on the position indicator is the normal or spring return position. When the actuator is mounted with the “R” side facing the installer and the control signal increases the actuator will rotate in the counterclockwise direction.

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. Note: To check out a normally opened actuator the procedure is the same as below, except the initial position is open and closed when powered. -
