Use
The rotary actuators are used in ventilation and air conditioning plants to regulate and shut
off air dampers:
For damper areas up to 3 m
2
, friction-dependent
Suitable for three-position controllers (e.g. for outside air dampers).

Control type
Open-close / three-position
Rotary direction
Clockwise or counter-clockwise direction depends …
… on the type of control
… on the setting of the rotary direction switch.
With no power applied, the actuator remains in the respective position.
Position indication:
Mechanical
Rotary angle position indication by using a position indicator.
Position indication:
Electrical
-
The feedback
potentiometer can be
connected to external
voltage to indicate the
position.
-
Auxiliary switch
-
-
The switching points for
auxiliary switches can
be set in increments of
10° within 0° to 90°.
Manual adjustment
The actuator can be manually adjusted by pressing the gear train disengagement
button.
Rotary angle limitation
The rotary angle of the shaft adapter can be limited mechanically with a set screw.
Technical design
Housing
The housing consists essentially of fire-retardant UL94-5V ABS engineering plastic
Actuator motor / Gears
● Brushless, robust DC motors ensure reliable operation regardless of load. The damper ac-
tuators do not require an end position switch, are overload proof, and remain in place upon
reaching the end stop.
● The gears are maintenance free.
