Figure 12. Self-adapt Switch in the On Position.
Factory setting 0 (OFF)
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 GDE/GLB163x and GDE/GLB164x only
Slope (span) ∆U ≈10
Offset Uo = 0
Use a flat-blade screwdriver to
make adjustments. The long arm of
points to the setting.

All wiring must conform to NEC and local codes and
Use earth ground isolating step-down Class 2
transformers. Do not use autotransformers.
Determine the supply transformer rating by summing
total VA of all actuators used. It is recommended that
one transformer power no more than 10 actuators.
Counterclockwise Damper Rotation of GDE/GLB13x
If the damper blades turn counterclockwise to open (CCW),
reverse the 6 (violet) and 7 (orange) wires at the controller.
All wiring for CE rated actuators must only
be separated extra low voltage (SELV) or
protective extra low voltage (PELV) per
Use safety-isolating transformers (Class
III transformer) per EN 61558. They must
be rated for 100% duty cycle.
Overcurrent protection for supply lines is
Do not wire different types of actuators (such as
GBB or GIB actuators) in parallel with these
