OPERATION

The actuator is designed to be used in ventilating and air 

conditioning installations to operate valves, dampers, 

ventilation flaps and louvers. (For ratings, see the 

Specifications section.) If the power fails, the actuator will 

spring return to the fail safe position.

When using a proportional controller, the actuator drives 

toward its fully open position when the input signal increases; 

the actuator drives toward the fully closed position when the 

input signal decreases. The actuator stops when the input 

signal reaches the desired proportional control point. This 

operates in reverse when set to a 10-2(0) position.

IMPORTANT

The actuator is designed to respond to DDC 

Controller instantaneous contact closures. Take care 

not to short cycle the actuator. Unstable damper 

control can cause premature actuator failure.

Actuator Override

To override the control signal (for freeze protection or similar 

applications):

1.

Override to full open:

a. Disconnect the input signal (from terminal 3).

b. Apply 24 Vac to terminal 3.

c. See Fig. 22.

2.

Override to full closed:

a. Disconnect the input signal (from terminal 3).

b. See Fig. 23.
