Data interrogation
31
11/04 MN01219002Z-EN
Parameters
Displays the parameters of the NZM. It must be remembered
that the actual parameters used are displayed and not those
values that are set directly on the switches of the NZM. This
distinction is important if parameter settings were
transferred to the NZM via the DMI or via a bus system.
These can then differ from the device settings. A parameter
deviation of this nature is indicated by flashing of parameter
LED
d
(
a
fig. 1, Page 12) on the DMI.
Currents
The actual values of the individual currents can be called in
this submenu. The individual phase and neutral pole currents
(
I
1
to
I
4
) and (if available) the differential current
I
dn
.
The display format depends on the setting selected. It is
either displayed as a relative value, i.e. in relation to
I
r
[%],
or as an absolute value in Amps.
I/O status
The status of the inputs and outputs on the DMI can be
interrogated via this option. The inputs and outputs are
displayed in separate lines with “0” for “OFF” and “1” for
“ON”.
When interpreting the display, remember that the inputs and
outputs are displayed according to their spatial positioning
in the device, i.e. I0
is on the far left and I5 is on the far right
in the display.

Only those parameters are displayed that the connected
circuit-breaker actually supports. It is therefore not
possible, for example, to display parameter

dn
on a
circuit-breaker of frame size 2, as it is not available with
this size.
