Operation, characteristics of the UK24LON unit
Automatic scanning
of the MP network
As soon as the UK24LON unit is power-
ed up it starts scanning the MP network
automatically. All eight MP addresses are
interrogated cyclically to see whether the-
re is an actuator available to respond. The
results are compared against a reference
table stored in the UK24LON unit. If an ac-
tuator responds from an MP address that
is not assigned in the reference table it is
automatically inserted into the table.
If an actuator already assigned in the refer-
ence table fails to respond an error alarm
is initiated but the reference table is not
altered in any way. The actuators can be
pre-addressed so that they are recognis-
ed automatically when they are connect-
ed to the MP network.
Manual addressing

All required actuators must be connect-
●
ed first.

Within the next 10 minutes, the MFT(2)/
●
MP actuator being addressed must be
reset (in the case of standard damper
actuators by pressing the addressing
button; in the case of spring return ac-
tuators by moving the L/R switch back
and forth and in the case of globe valve
actuators by pressing the S2 button).
The UK24LON unit will then be able to
recognise and address the actuator.
This status is indicated by fast flashing
of the Reg'd LED
As soon as addressing of the actua-
●
tor has been completed the Reg'd LED
– gives a steady light. This also indi-
5
cates that the MP address has been
successfully stored in the reference ta-
ble of the UK24LON unit.
Notes on addressing
If none of the actuators has been re-
●
set within 10 minutes of the addressing
process being initiated, the process will
be discontinued. The reference table re-
