Mounting bracket Operation A continuous 0(2) to 10 Vdc signal from a controller to wire 8 (Y) operates the damper actuator. The angle of rotation is proportional to the control signal. A 0 to 10 Vdc position feedback output signal is available between wire 9 (U) and wire 2 (G0) to monitor the position of the damper motor. In the event of a power failure, the actuator holds its position. In the event that only the control signal is lost, the actuator returns to the 0 position. Life expectancy An improperly tuned loop will cause excessive repositioning that will shorten the life of the actuator. Control signal adjustment GDE163.1P and GDE164.1P: For sequencing and the electronic limitation of the angle of rotation. Use the Uo potentiometer to set the offset (start point) between 0 to 5 Vdc. Use the U potentiometer to set the span between 2 to 30 Vdc.

Adjustable Switching Values for the Dual Auxiliary Switches. NOTE: The auxiliary switch setting shafts rotate with the actuator. The scale is valid only when the actuator is in the 0 position on clockwise motion. Use the long arm of the † ( AUX SWITCH ADJUSTMENT ) to point to the position of Switch A. Use the narrower tab on the red ring to point to the position of Switch B. Rotation Direction GDE14x.1P, GDE34x.1U Two-position/Floating Control Figure 13. Setting the Rotation Direction. OpenAir™ GDE Enhanced Non-Spring Return Rotary Electric Damper Actuator Technical Instructions Document Number 155-784 January 20, 2017 Siemens Industry, Inc. Page 9 Rotation Direction Switch Counterclockwise Clockwise Figure 14. Direction of Rotation Switch. The factory setting is clockwise. The direction of rotation switch should match the damper rotation movement. Dual in-Line Package (DIP) Switches GDE16x.1P Raise the protective cover from left to right to locate the DIP switches. See Figure 9 for the location of the cover. Modulating control signal selection Figure 15. 0 to 10 Vdc Position (Factory Setting). To change the control signal from the factory setting (0 to 10 Vdc), move the first DIP switch to the UP (2-10) position. Self-adapt Switch Figure 16. OFF Position (Factory Setting). The factory setting is 0 (OFF). When mechanical angle of rotation is limited, the self-adapt switch (middle DIP switch) may be turned ON so that the limited range will become the new 0 to 100% for the actuator logic. In this case, 0 to 100% is not equal to 90° CAUTION: When turning the self-adaptive feature on or after the software reset with the feature on, the actuator will enter a five-minute calibration cycle as the actuator adjusts to the rotation limits of the system. A software reset happens after power on or may be caused by electrostatic discharge (ESD) at levels of 2kV and above. The self-adapt capability will scale the control signal selected, either a 0 to10 Vdc or a 2 to 10 Vdc signal, within the adjusted mechanical range. The feedback signal will also reflect the control signal selected, either a 0 to 10 Vdc or a 2 to 10 Vdc. Next >
