Gateway MP to LONWORKS®
● MP/LON interface
● MFT(2)/MP actuators (with MP
communications capability)
linked to LONWORKS® through
a UK24LON unit
● Up to 8 actuators
can be connected
● LONMARK® certified
Application
The UK24LON unit is a Belimo gateway
that has been certified by LONMARK®. It
allows the Belimo MP-Bus to be linked to
LONWORKS®.
Up to 8 MP capable actuators can be
connected to the MP-Bus side of the sys-
tem (damper actuators, valve actuators
and VAV-Compact).
Mode of operation
Through the UK24LON unit the actua-
tors can be controlled digitally over the
MP-Bus and they also provide feedback
of their current operating status. In the
UK24LON unit the digital data for control
and feedback is converted to standard
network variables (SNVT’s). This allows
the functions of the actuators to be linked
directly to LONWORKS®.
Sensor connection
One sensor can be connected to each
MFT2 actuator. It can be either a passive
resistance-type sensor (Pt1000, Ni1000
or NTC), an active sensor (e.g. with a
DC 0...10 V output) or a switching con-
tact. This provides a simple means of
digitising the analogue signal from the
sensor through the actuator so that it
can be passed on to LONWORKS® via the
UK24LON unit.
Parameterising MFT(2)/MP actuators
Using the Belimo PC-Tool it is very easy to
preset specific parameters (e.g. running
time) for individual actuators. An MFT pa-
rameterising tool can be connected to the
3-pole plug socket of the UK24LON unit.
Important installation note!
Do not energise the system
(UK24LON and actuators) until
all the wiring has been finished.
