Fields of application
The actuator is particularly suitable for utilisation in outdoor applications and is
protected against the following weather conditions:
- UV radiation
- rain / snow
- dirt / dust
- Humidity
- Changing atmosphere / frequent and severe temperature fluctuations
(recommendation: use the actuator with integrated factory-installed heating which can
be ordered separately to prevent internal condensation)
Mode of operation
The actuator is connected with a standard modulating signal of DC 0...10V and drives
to the position defined by the positioning signal. Measuring voltage U serves for the
electrical display of the damper position 0...100% and as slave control signal for other
actuators.
Parameterisable actuators
The factory settings cover the most common applications. Single parameters can be
modified with the Belimo Service Tools MFT-P or ZTH EU.
Simple direct mounting
Simple direct mounting on the damper spindle with an universal spindle clamp,
supplied with an anti-rotation device to prevent the actuator from rotating.
Manual override
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
The housing cover must be removed for manual override.
High functional reliability
The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.
Adjustable angle of rotation
Adjustable angle of rotation with mechanical end stops. Standard setting 0 ... 90°. The
housing cover must be removed to set the angle of rotation.
Home position
The first time the supply voltage is switched on, i.e. at the time of commissioning, the
actuator carries out a synchronisation. The synchronisation is in the home position
(0%).
The actuator then moves into the position defined by the positioning signal.

Adaption and synchronisation
An adaption can be triggered manually by pressing the “Adaption” button or with the
PC-Tool. Both mechanical end stops are detected during the adaption (entire setting
range).
Automatic synchronisation after pressing the gearbox disengagement button is
configured. The synchronisation is in the home position (0%).
The actuator then moves into the position defined by the positioning signal.
A range of settings can be adapted using the PC-Tool (see MFT-P documentation)
