3.20.4 Fault Recordings
Protection signals, including the signals during the settable pre-fault and post-
fault times, are logged in chronological order with reference to the specific fault.
A total of eight faults, each involving a maximum of 200 start or end signals, can
be stored in the non-volatile fault memories. After eight faults have been
recorded, the oldest fault recording will be overwritten, unless memories have
been cleared in the interim. If more than 199 start or end signals have occurred
during a single fault, then FT_RC: Fault mem. overflow will be entered as the
last signal. If the time and date are changed during the pre-fault time, the signal
FT_RC: Faulty time tag is generated.
In addition to the fault signals, the measured RMS fault data will also be entered
in the fault memory.
The fault recordings can be read from the local control panel or through the PC or
communication interfaces.
