If there are further faults, the faults are displayed as follows:
• The fault LED lights up.
• The error code of the last fault is shown in the display.
All other faults can be called up from the fault memory.
If all faults have been rectified, acknowledge the faults again.
The switchgear stores the last ten faults in the fault memory. The fault memory works ac-
cording to the first in/first out principle. The faults are displayed in descending order in the
menu items 6.02 to 6.11:
• 6.02: the last/latest fault
• 6.11: the oldest fault
The functions may operate differently depending on the software version. That is why a
software version is included with every error code.
The details regarding the software version used can be read on the rating plate or displayed
via menu 4.24.
