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 and actuator is set to
(0)2 - 10 position, 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 fail-
ure.
Fast commissioning mode
(modulating control mode only)
When 24 VAC or 24 VDC signal is applied to the
modulating input, the actuator will drive to the fully open
position with higher speed corresponding to 30 sec
