Technical Instructions Document No. 155-188P25 May 22, 2014 OpenAir™ Non-Spring Return, 24 Vac, Floating Control, Rotary Electric Damper Actuator A floating control signal controls the damper actuator. The actuator’s angle of rotation is proportional to the length of time the signal is applied. A 24 Vac control signal to wires 1 and 6 (G-Y1) causes the actuator coupling to rotate clockwise. A 24 Vac control signal to wires 1 and 7 (G-Y2) causes the actuator coupling to rotate counterclockwise.
OpenAir™ Non-Spring Return, 24 Vac, Floating Control, Rotary, Electric Damper Actuator Mounting and Installation Technical Instructions Document No. 155-188P25 May 22, 2014 You must place the actuator on the damper shaft so that the front of the actuator is accessible. The label is on the front side. The minimum damper drive shaft length is 3/4-inch (20 mm).
Technical Instructions Document No. 155-188P25 May 22, 2014 Wiring OpenAir™ Non-Spring Return, 24 Vac, Floating Control, Rotary Electric Damper Actuator All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers. The sum of the VA ratings of all actuators and all other components powered by one transformer must not exceed the rating of the transformer.
