ASF 123S: Actuators with spring return and positioner

For controllers with continuous output (0...10 V). For the operation of air dampers, frost-protection
dampers and smoke-shut-off dampers, for example. In the event of a power failure or when a safety
device is activated, it returns to the original position.
Two-piece housing of cast light metal containing the motor, electronic control unit, return spring,
gearbox and positioner. Electronic, torque-based cut-out by means of stops on either the actuator or
the air damper; the direction of rotation can be reversed by fitting the unit the other way round. Included
in delivery: clamp-on lever, fixing bracket as anti-torsion device, Allen key for making manual
adjustments and winding up the spring, position indicator and two screws. Power cable is 0,9 metres
long, 4× 0,75 mm², and fixed to the housing.

Operation

The in-built positioner controls the servo-motor in relation to the controller's output signal y. As the
output signal rises, the coupling piece turns towards 90° (scale on drive) until the force-dependent cut-
out facility operates. In the two end positions (on reaching either the damper stop, the stop of the angle
limiter or the maximum angle of 95°) or in the event of an overload, the torque-dependent cut-out
comes into operation (no limit switches). In the event of a power failure, or when the power is switched
off by a safety device at terminal 2 (red wire), the motor releases the gears, and the coupling piece is
turned back by the spring to the 0° position.
The direction of rotation for the safety function is chosen by fitting the actuator onto the damper spindle
accordingly. A signal converter is required for the opposite direction of operation.

Engineering and fitting notes

The use of electronics allows several dampers with different torques to be run in parallel. It is essential
that the operating voltage lies within the prescribed tolerances. The drives must not be mechanically
coupled. The drive, which can be fitted in any position, is fitted directly onto the damper shaft and fixed
using the self-centring clamp.
The subsequent fitting of auxiliary switches or potentiometers is not possible.
The angle of rotation can, between 0° and 90°, be limited in steps of 5°.
N.B.: The housing must not be opened, since the return spring may cause injury.
Fitting outdoors. If the devices are fitted outdoors, we recommend that additional measures be taken
to protect them against the effects of the weather.
