Safety notes
!
• The device must not be used outside the specified field of application, especially not
in aircraft or in any other airborne means of transport.
• Only authorised specialists may carry out installation. All applicable legal or
institutional installation regulations must be complied during installation.
• Junction boxes must at least correspond with enclosure IP degree of protection!
• The cover of the protective housing may be opened for adjustment and servicing.
When it is closed afterwards, the housing must seal tight (see installation
instructions).
• The device may only be opened in the manufacturer’s factory. It does not contain
any parts that can be replaced or repaired by the user.
• The cables must not be removed from the device installed in the interior.
• Self adaption is necessary when the system is commissioned and after each
adjustment of the angle of rotation (press the adaption push-button once).
• 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 not designed for applications where chemical influences (gases,
fluids) are present or for utilisation in corrosive environments in general.
• The actuator may not be used in plenary applications (e.g. suspended ceilings or
raised floors).
• The materials used may be subjected to external influences (temperature, pressure,
construction fastening, effect of chemical substances, etc.), which cannot be
simulated in laboratory tests or field trials. In case of doubt, we definitely recommend
that you carry out a test. This information does not imply any legal entitlement.
Belimo will not be held liable and will provide no warranty.
• If cables which are not authorised for UL (NEMA) Type 4 applications are guided out
of the unit, then flexible metallic cable conduits or suitable threaded cable conduits
of equal value are to be used.
Product features
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.
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.
