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.
