Technical Instructions listed in References.
Mechanical Range Limitation and
Self–adapt Feature
1. To use the entire 0(2) to 10V input signal to
control the adjusted range, raise the tab located
on the lower left-hand side of the actuator and
locate the DIP switches. See Figure 15.
2. Set the self-adapt DIP switch (middle) to (ON).
Figure 15. Self-adapt Switch in OFF Position
(Factory Setting).
3. Close the tab over the DIP switches.
For example, if you set the locking screw at 70° and
turn the self-adapt switch ON, a 5V input signal will
drive the damper to 35° (50% of its adjusted range).
CAUTION:
When turning the self-adaptive feature on, or
after 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. The software reset happens after
power on, or may be caused by electrostatic
discharge (ESD) at levels of 2 kV and above.
Slope (Span) and Offset Adjustment
For GDE163x and GDE164x only
Factory setting:
Slope (span) U 10
Offset Uo = 0
Use a flat-blade screwdriver to
make adjustments. The long arm of
the † points to the setting.
