Manual Settings Change
Relay configuration changes during a user-initiated manual setting; the change
does not disrupt the relay protection functions. The relay logs an acceptance of
the change request and puts the new setting file in service. When the new set-
ting file is queued the relay loads the new setting configuration for protection
functions to the protection processor. The relay loads the new name definitions
for indication and recording functions to the interface processor. When the re-
lay has completed loading the ancillary settings for indication purposes to the
interface processor, an event is logged to show completion of the request.
There is some lag time during the load request and the completion of the re-
quest where the interface processor associates ancillary functions with the pre-
vious setting file for approximately five seconds. The ancillary setting
information includes channel or ProLogic and Group Logic statements names,
front panel target light activation rules and record initiation rules.
The protection processor does not have any interruption in service.
Automatic Settings Change
Relay configuration changes during a relay-initiated setting; change does not
disrupt the relay protection functions. Since the relay setting file does not
change, the interface processor uses the new setting group ancillary setting in-
formation at the same time as the protection processor switches to the new set-
ting group. An event is logged to show when the new setting group is in
service.
