3.18.4 Overload Logging
Protection signals during an overload event are logged in chronological order
with reference to the specific event. A total of eight overload events, each
involving a maximum of 200 start or end signals, can be stored in the non-
volatile overload memories. After eight overload events have been logged, the
oldest overload log will be overwritten, unless memories have been cleared in
the interim. If more than 199 start or end signals have occurred during a single
overload event, then OL_RC: Overl. mem. overflow will be entered as the
last signal.
In addition to the signals, the measured overload data will also be entered in the
overload memory.
The overload logs can be read from the local control panel or through the PC or
communication interfaces.
