When you have made all the necessary setting changes, it is not necessary to scroll through the
remaining settings. Type
END<ENTER>
at the next setting prompt to display the new settings
and request confirmation.
Answer
Y<ENTER>
to the confirmation request to approve the new settings. If you violate a
rule for setting relationships, a fail message is displayed, and the settings prompt moves to the
first setting that affects the failure. While the active settings are updated, the relay is disabled,
the ALARM output contacts close, and all timers and relay elements reset. The relay logic is
fully functional while editing settings. The relay is disabled for approximately one second when
settings are saved.
Refer to individual elements in
Section 3: Differential, Restricted Earth Fault, Overcurrent,
Voltage, and Frequency Elements
and to
Section 6: Setting the Relay
for information on
settings.
SET G (Edit Global Settings)
Access Level 2
Configure the relay Global Settings using the
SET G
command. The Global Settings include
Event Report parameters, frequency, phase rotation, date format, front-panel time-out, the group
switching time delay, dc battery monitor thresholds, breaker monitor settings, analog input
labels, SSn setting group variables, and definition of front-panel programmable LED and Display
Point variables. The entire syntax of the
SET G
command follows:
SET G
Setting
TERSE<ENTER>
The two parameters are optional and perform the following functions:
Setting
specifies the setting name with which to begin. The default is the first setting.
TERSE
eliminates the display of the Global Settings at the end of the setting procedure.
The command will function properly if just
TE
is entered, instead of the full word.
The SET G procedure works just like the SET procedure. Table 7.4 lists the editing keys that
you can use with the
SET
command.
Refer to individual elements in
Section 3: Differential, Restricted Earth Fault, Overcurrent,
Voltage, and Frequency Elements
and to
Section 6: Setting the Relay
for information on
settings.
SET P (Edit Port Settings)
Access Level 2
Configure the relay port settings using the
SET P
command. The port settings include the
communication and protocol settings. The entire syntax of the
SET P
command follows:
SET P n
Setting
TERSE<ENTER>
The two parameters are optional and perform the following functions:
n
specifies the serial port number (1, 2, 3, or 4). Default is the port issuing the command.
