Page 7 Operation A continuous 0 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 GDE/GLB163.1P and GDE/GLB164.1P: 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 slope (span) between 2 to 30 Vdc. NOTE: The Y input is limited to a maximum of 10 Vdc. If the sum of the offset and slope setting is greater than 10V, the angle of rotation is reduced providing the feature of electronic limitation of the angle of rotation. Figure 14.

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.

Page 9 Dual in-Line Package (DIP) Switches GDE16x.1P GLB16x.1P Raise the protective cover from left to right to locate the DIP switches. See Figure 11 for the location of the cover. Figure 18. Self-adapt Switch. The factory setting is 0 (OFF). When mechanical angle of rotation is limited, the self-adapt 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 position output signal U is not influenced by the self- adapt function. The 0 to 10V feedback signal U is always proportional to 0° to 90° (or 90° to 0°). Figure 19. Direction of Rotation Switch. The factory setting is clockwise. The direction of rotation switch should match the damper rotation movement. Figure 20. Output Signal Switch. The factory setting is direct acting. As the clockwise angle of rotation increases, the output voltage increases. If the direction of rotation is counterclockwise, the output signal switch should be set at reverse acting to match the direction of the rotation switch. Next >
