Configuration of the loaD Monitoring unit
note :
The asterisks (
¶
) correspond to the standard configuration of the
LMU 212 version 0XX and LMU 217 version 0XX, that is to say
the basic uncalibrated modules.
The configuration of the LMU 212 and LMU 217 load monitoring units include all start-up operations
which are necessary to achieve a trouble free operation. This ranges from the supply voltage to
the selection of the application, the sensor connection, the energising mode of the relays and their
delay time, the selection of the pass-band and the sensor sensitivity. As a reminder: the LMU 217
is composed of two LMU 212.

Supply voltage
Before connecting the LMU 212 or LMU 217 load monitoring unit, select its operating voltage by
correctly positioning the jumper (DC or AC voltage) and then, in case of an AC supply, choosing
the correct voltage by means of the switch. Finally choose the supply fuse rating.
WARNING! The moNIToRING uNIT cAN be seRIously

The information given in
figures 2–4
to
2–6
and in the table on the next page allows the user to
select the operating voltage of the load monitoring unit, to choose the supply fuse and to assign the
supply terminals.
