Technical Instructions OpenAir™ GDE Enhanced Non-Spring Return Rotary Electronic Damper Actuator Document Number 155-784 January 20, 2017 The type of actuator required depends on several factors. Sizing 2 2 1. Obtain damper torque ratings (ft-lb/ft or Nm/m ) from the damper manufacturer. 2. Determine the area of the damper. 3.
OpenAir™ GDE Enhanced Non-Spring Return Rotary Electric Damper Actuator Manual Override Technical Instructions Document Number 155-784 January 20, 2017 To move the damper blades and lock the position with no power present: 1. Slide the red manual override knob toward the back of the actuator. 2. Make adjustments to the damper position. 3. Slide the red manual override knob toward the front of the actuator. Once power is restored, the actuator returns to automated control.
