This can be inverted in cases of control with an analogue positioning signal. The inversion causes the

reversal of the standard behaviour, i.e. for control signal 0%, the actuator is opened to max and for

control signal 100%, the actuator is closed.

For fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in

accordance with the damper manufacturer’s specifications. The actuator is mounted directly to a damper

shaft up to 1.05” in diameter by means of its universal clamp. A crank arm and several mounting brackets

are available for applications where the actuator cannot be direct coupled to the damper shaft. The

actuator operates in response to a 2 to 10 VDC or, with the addition of a 500Ω resistor, a 4 to 20 mA

control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for

position indication. Not to be used for a master-slave application.

Simple direct mounting on the damper shaft with a universal shaft clamp, supplied with an anti-rotation

device to prevent the actuator from rotating.

The recorded data (integrated data recording for 13 months) can be used for analytical purposes.

Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or

remains locked).

Adjustable angle of rotation with mechanical end stops.

The actuator is overload protected, requires no limit switches and automatically stops when the end stop

is reached.

The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out

an adaption, which is when the operating range and position feedback adjust themselves to the

mechanical setting range.

The actuator then moves into the position defined by the positioning signal.

An adaption can be triggered manually by pressing the "Adaption" button. Both mechanical end stops are

detected during the adaption (entire setting range).

The actuator then moves into the position defined by the positioning signal.
