12.5 Events and Actions
This table describes the events that control and are
generated by the self-monitoring features of the relay.
They are listed in numerical order by their event
identification number (shown in the “Event” column).
The text in the “LCD Abbreviation” column is the
corresponding text that will appear when viewing logs
on the front panel LCD display. In the “Oper” column, a
letter “C” or “G” indicates that the “Coming” and/or
“Going” events are logged in the Operational Log,
while if in the “Fault” column they indicate that the
events are logged in the open fault log. A letter in the
“In/Out” column indicates that the event can control an
LED and/or signal contact (“S”), and/or control a trip
(command) contact (“T”).
