OpenAir GEB Non-Spring Return Rotary Electronic Damper Actuators The angular rotation is adjustable between 0 and 90° at 5-degree intervals. The range of shaft movement is limited by mounting the shaft adapter: 1. Loosen the shaft adapter from the damper shaft and remove the actuator from the damper shaft. 2. Remove the clip and shaft adapter from the actuator. 1 2 EA0947R1 Mechanical Range Adjustment Technical Instructions Document Number 155-318P25 August 27, 2007 Figure 8.

OpenAir GEB Non-Spring Return Rotary Electronic Damper Actuators Wiring Technical Instructions Document Number 155-318P25 August 27, 2007 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 maximum rating for a Class 2 step-down transformer is 100 VA. Determine the supply transformer rating by summing the VA ratings of all actuators and all other components used.
