Instruction Manual SEL-351-5, -6, -7 Relay
SEL-351-5, -6, -7 Relay Command Summary
Access Level 1
Commands The Access Level 1 commands allow the user to look at settings information and not change it,
and to retrieve and reset event, recorder, and metering data. The screen prompt is:
=>
STA Show relay self-test status.
TAR n k Display Relay Word row. If n = 0–62, display row n . If n is an element name (e.g., 50A1), display row
containing element n . Enter k for repeat count ( k = 1–32767, if not specified, default is 1).
TAR LIST Shows all the Relay Words in all of the rows.
TAR R Reset front-panel tripping targets.
TAR ROW ... Shows the Relay Word row number at the start of each line, with other selected Target commands as
described above, such as
n , name , k , and LIST.
TIM Show or set time (24-hour time). Show current relay time by entering TIM . Set the current time by entering
TIM followed by the time of day (e.g., set time 22:47:36 by entering TIM 22:47:36 ).
TRI [ time ] Trigger an event report. Enter time to trigger an event at an exact specified time, in 24-hour format.
a
Available in firmware versions 6 and 7.
b
Available in firmware version 7.
Access Level B
Commands Access Level B commands primarily allow the user to operate the breaker and output contacts. All
Access Level 1 commands can also be executed from Access Level B. The screen prompt is:
==>
BRE n Enter BRE W to preload breaker monitor data. Enter BRE R to reset breaker monitor data.
CLO Close circuit breaker (assert Relay Word bit CC).
GRO n Change active group to group n ( n = 1–6).
OPE Open circuit breaker (assert Relay Word bit OC).
PUL n k Pulse output contact n (where n is one of
ALARM
,
OUT101
–
OUT107
,
OUT201–OUT212
) for k seconds. Specify
parameter n ; k = 1–30 seconds; if not specified, default is 1.
Access Level 2
Commands
The Access Level 2 commands allow unlimited access to relay settings, parameters, and output
contacts. All Access Level 1 and Access Level B commands are available from Access Level 2. The
screen prompt is:
=>>
CON n Control Relay Word bit RB n (Remote Bit n ; n = 1–16). Execute CON n and the relay responds: CONTROL RBn .
Then reply with one of the following:
SRB n set Remote Bit n (assert RB n ).
CRB n clear Remote Bit n (deassert RB n ).
PRB n pulse Remote Bit n [assert RB n for 1/4 cycle].
COP m n Copy relay and logic settings from group m to group n ( m and n are numbers 1–6).
LOO p t
a
Set M
IRRORED
B
ITS
port p to loopback ( p = A or B). The received M
IRRORED
B
ITS
elements are forced to
default values during the loopback test; t specifies the loopback duration in minutes ( t = 1–5000, default is 5).
LOO p DATA
a
Set M
IRRORED
B
ITS
port p to loopback. DATA allows the received M
IRRORED
B
ITS
elements to change during
the loopback test.
PAS 1 Change access level 1 password.
PAS B Change access level B password.
PAS 2 Change access level 2 password.
Entering DISABLE as the password disables the password requirement for the specified access level.
SET n Change relay settings (overcurrent, reclosing, timers, etc.) for group n ( n = 1–6, if not specified, default is active
setting group).
SET n L Change SEL
OGIC
control equation settings for group n ( n = 1–6, if not specified, default is the SEL
OGIC
control
equations for the active setting group).
SET ... name For all SET commands, jump ahead to specific setting by entering setting name.
SET G Change global settings.
SET P p Change serial port p settings, ( p = 1, 2, 3, or F; if not specified, default is active port).
SET R Change SER and LDP Recorder
a
settings.
