  • Page 7 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 8 Mounting the Actuator for Clockwise or Counterclockwise Spring Return 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 open actuator the procedure is the same as below, except the initial position is open and the powered position is closed.
