Instructions for the FP-6000 Protective Relay
Every time a protective function operates, it is recorded in the
Event log, by default and no extra programming is needed. Note,
most values given with each log can be accessed by selecting the
line immediately below the Cause and pressing Enter. The
information given is a group of status flag states at the time of
the event. Table 62 shows all of the protective operations that
can be logged in the Event log.
