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.
