Use
Rotary actuators are used in ventilation and air conditioning plants to regulate and shut off
air dampers:
●For damper areas up to approximately 4 m2 (Guideline: Always comply with the damper
manufacturer's specifications).
●Suitable for use with 2-position and 3-position controllers as well as modulating
controllers (DC 0/2…10 V) to control air dampers.
●We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3-
point control to ensure continuous and accurate operation.

Position indication
Mechanical
Rotation angle position indication using a position indicator.
Position indication
Electric
By connecting the feedback potentio-
meter to external voltage, output voltage
is generated proportional to rotation
angle.
Position indicator: Output voltage
U = DC 0/2…10 V is generated proportional
to rotation angle.
The direction of rotation (inverted or non-
inverted) for output voltage U is based on
the DIL switch position.
Auxiliary switch
The switching points for auxiliary switches A and B can be set independently in
increments of 5° from 0 to 90°.
Self-adaptation of the
rotation angle range
-
The actuator automatically determines the
mechanical end positions of the rotation
angle range.
The characteristic function (Uo, ΔU) is
mapped to the calculated rotation angle
range.
Power must be connected to DIL switch 2
(self-adaptation) for the function to operate.
Manual adjustment
The actuator can be manually adjusted by pressing the gear train disengagement
button.
Rotation angle limitation
A set screw can limit the rotation angle to between 0° and 90°.

Technical design
Housing
●Robust and light cast aluminum housing. The housing guarantees long life, even under
harsh ambient conditions.
Actuator / gears
●Brushless, robust DC motors ensure reliable operation regardless of load. The damper
actuators do not require an end position switch, are overload proof, and remain in place
upon reaching the end stop.
●The gears are maintenance free and low noise.
