Belimo Gateway MP to BACnet MS/TP



The device is not allowed to be used outside the specified field of application.



It may be installed only by suitably trained personnel.



The device does not contain any parts that can be replaced or repaired by the user

and may only be opened at the manufacturer's site.

The UK24BAC allows the actuators to be controlled digitally via the MP-Bus and send back their

current operating status. The control system information and the response is administered in

BACnet objects in the UK24BAC and can be processed with BACnet services. This permits the

actuator functions to be integrated directly into BACnet.

One sensor can be connected per MP/MFT(2) actuator. This can be a passive resistance

sensor (PT1000, NI1000 or NTC), an active sensor (output DC 0...10 V), or a switching contact.

This provides a straightforward way of digitising the analogue signal of the sensors with the

Belimo actuator and transferring it via UK24BAC to the BACnet.

MPL actuators don't provide a sensor input.

The device is mounted on 35 mm top hat rails. The wiring is accomplished with plug-screw

terminals.

Commissioning requires no configuration tools.

The BACnet MS/TP parameterisation of the device is accomplished with DIP switches:

MAC Address (TS), baud rate, bus terminator, biasing

The BACnet Device Address (Device Object Identifier, Device Object Name) is calculated

based on the MAC Address setting (TS) and an adjustable offset value (see chapter 'PICS' for

details). The resulting Device Address with factory-set offset and TS=1 is:

Device Object Identifier:

Device Object Name:

The parameterization of the sensors which are connected to the actuators and other settings

can be done with any BACnet Client.

The addressing of the MP actuators is accomplished either with the keys under the front cover

or with the Belimo PC-Tool MFT-P.

The MP-Bus assignment is determined automatically and continuously updated. No backup of

the network structure takes place.
