• The device must not be used outside the specified field of application, especially not
!
in aircraft or in any other airborne means of transport.
• Outdoor application: only possible in case that no (sea)water, snow, ice, insolation
or aggressive gases interfere directly with the actuator and that is ensured that the
ambient conditions remain at any time within the thresholds according to the data
sheet.
• Only authorised specialists may carry out installation. All applicable legal or
institutional installation regulations must be complied during installation.
• The device may only be opened at the manufacturer's site. It does not contain any
parts that can be replaced or repaired by the user.
• Cables must not be removed from the device.
• To calculate the torque required, the specifications supplied by the damper
manufacturers concerning the cross-section, the design, the installation site and the
ventilation conditions must be observed.
• The device contains electrical and electronic components and must not be disposed
of as household refuse. All locally valid regulations and requirements must be
observed.
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.
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 on the damper spindle with an universal spindle clamp,
supplied with an anti-rotation device to prevent the actuator from rotating.
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.
Adjustable angle of rotation with mechanical end stops.
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.
