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.
• 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.
Product features
Mode of operation
The actuator is fitted with an integrated interface for BACnet MS/TP, Modbus RTU and
MP-Bus. It receives the digital positioning signal from the control system and returns
the current status.
Converter for sensors
Connection option for a sensor (passive, active or with switching contact). In this way,
the analogue sensor signal can be easily digitised and transferred to the bus systems :
BACnet, Modbus or MP-Bus.
Parametrisable actuators
The factory settings cover the most common applications. Single parameters can be
modified with the Belimo Service Tools MFT-P or ZTH EU.
The communication parameters of the bus systems (address, baud rate etc.) are set
with the ZTH EU. Pressing the “Address” button on the actuator while connecting the
supply voltage, resets the communication parameters to the factory setting.
Quick addressing: The BACnet and Modbus address can alternatively be set using the
buttons on the actuator and selecting 1...16. The value selected is added to the «Basic
address» parameter and results in the effective BACnet and Modbus address.
Combination analogue - communicative
(hybrid mode)
With conventional control by means of an analogue positioning signal, BACnet or
Modbus can be used for the communicative position feedback
Simple direct mounting
Simple direct mounting on the damper shaft with a universal shaft 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).
Adjustable angle of rotation
Adjustable angle of rotation with mechanical end stops.
