The fault locator has influence over information in the EVENT and LOCAT
columns. If the fault locator is enabled (enable setting EFLOC = Y), the fault
locator will attempt to run if the event report is generated by a trip (assertion
of TRIP Relay Word bit) or other programmable event report trigger condition
(SEL
OGIC
®
control equation setting ER).
If the fault locator runs successfully, the location is listed in the
LOCAT column,
and the event type is listed in the
EVENT column:
If a trip occurs in the same event report, a “T” is appended to the event type
(e.g., AG T).
If the fault locator is disabled or does not run successfully,
$$$$$$$ is listed in
the
LOCAT column. For either of these cases where the fault locator does not
run, the event type listed in the
EVENT column is one of the following:
The
TARGETS column will display any of the following illuminated front-panel
target LEDs if the event report is generated by a trip (assertion of TRIP Relay
Word bit):
