Structure and design

The electronic motor-driven GEB..1 electronic actuators are available for three-position,
modulating and networked control. The maximum torque is 15 Nm. The actuator's
connection cables are prewired.
Robust, light-weight full metal housing from aluminum diecast. The housing guarantees
a long actuator life even under harsh environmental conditions.
Maintenance-free and noise-free gear train with stall and overload protection for the life
of the actuator.
This mounting type allows for fastening the actuator to shafts with various diameters
and in various shapes (square, round) using just one screw.
Insert the shaft adapter from either side into the opening for the shaft adapter.
For short shafts, the shaft adapter is on the duct side.
The shaft adapter coupling and the adapter holding are coupled by means of double-
sided gearing.
When no voltage is supplied, you can manually adjust the actuator or the air damper by
pressing the gear train disengagement button.
A bolted metal strip is used to attach the actuator.
All actuators have pre-wired 0.9 m long connection cables.
The actuators can be delivered as a type-specific variant having the following elements:
For supplementary functions, you can adjust auxiliary switches A and B on the actuator
front.
Both potentiometers for the characteristic functions Uo and
front.
The DIL switches exist only in modulating actuators and are accessible from the front
(see chapter 2.6 "Setting and operator elements").
The potentiometer is integrated and can be connected by means of a cable.
