As early warning stages are stored as well as actual trips, the
diagnostics data can help you to make preventative
examinations of the system for weak points so that trips do
not occur. For example, the diagnostics memory can help
you determine regular overshoots of alarm thresholds.

Current parameters

This submenu shows the parameters being used at present
by the circuit-breaker. This makes it possible to make a quick
comparison between the parameters used at the time of the
event and the currently set parameters.

Operating hours

In the operating hours submenu the hours of operation of
the DMI and NZM can be read off. The resolution is set to an
xh
hour. The entire operating time is indicated for the DMI. For
yh
the NZM, only the time with which it has been in
communication with the respective DMI is displayed. The
value is reset to 0 if there is an interruption in
communication.

Switching operations

In this submenu the switching operations of the connected
NZM are displayed whereby a switching operation is every
change of state from "ON" a "OFF", "ON"a "Trip",
"OFF" a "ON".
Similar to the operation time counter, this value is also lost
when there is a loss of communication.
