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
-
Protection Self Monitoring Occurrence
-
Internal Self Monitoring (see Section 12.2 on page 119)
Relay is operational and at least one protection function is active.
(This event is always marshalled to signal contact 5, and can be
marshalled to other contacts as well.)

Failure of the supply power de
relay.
Monitoring of CT Circuits (Section 12.4 on page 120)
Failure of current summation monitoring (only available when the
protected object is a bus)
Failure of current symmetry for at least one winding (or branch)
Failure of current symmetry for Winding 1 (or branch 1)

Monitoring
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").
