Description of operation2-point model:

After the power is connected, the control unit to be activated is moved in the direction of the 90° posi

tion until the power-dependent cut-off is performed (scale on actuator, max. angle of rotation 95°). In

the process, the gear unit with its brushless DC motor is stopped and blocked. If the power is cut off

or switched off, the motor releases the gear unit so that the spring turns the coupling piece back to

the 0° position.

3-point model:

The actuator turns from 0° to 90° when the power is applied to connection 2 (cable = violet), and from

90° to 0° when the power is applied to connection 3 (cable = orange). The actuator stops in the mid

dle position of the 3-point controller. If the power is cut off or is switched off by a safety device at con

nection 21 (cable = red), the gear unit is released so that the spring turns the coupling piece back to

the 0° position. In the two end positions (limit stop of damper, limit stop due to angle-of-rotation limit,

max. angle of rotation of 95° reached) or in the case of an overload, the torque-dependent cut-off is

activated (no limit switches).

Intended use

This product is only suitable for the purpose intended by the manufacturer, as described in the “De

scription of operation” section.

All related product documents must also be adhered to. Changing or converting the product is not ad

missible.

Engineering and fitting notes

The electronic concept enables the parallel operation of multiple air dampers with different torques.

However, it must be ensured that the operating voltage is within the required tolerance range. The

actuator can be fitted in any position. It can be plugged directly onto the damper spindle and is fixed

by means of the self-centring clamping lever.

No auxiliary switches or potentiometers can be installed subsequently.

The angle of rotation can be limited to between 0° and 90° in 5° stages
