SEL-351A 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: =>
SER d1 d2 Show all rows in the SER report recorded between dates d1 and d2, inclusive.
SER m n Show rows m through n in the SER report (m = 1–512).
SER n Show latest n rows in the SER report (n = 1–512, where 1 is the most recent entry).
SER C Clears SER report from nonvolatile memory.
SHO n Show relay settings (overcurrent, reclosing, timers, etc.) for group n (n = 1–6; if not specified, default is active
setting group).
SHO n L Show SEL
OGIC
®
Control Equation settings for group n (n = 1–6, if not specified; default is the SELOGIC control
equations for the active setting group).
SHO ... name For all SHO commands, jump ahead to specific setting by entering setting name.
SHO G Show global settings.
SHO P p Show serial port p settings, (p = 1, 2, 3, or F; if not specified, default is active port).
SHO R Show SER settings.
SHO T Show text label settings.
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
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) 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 RBn (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 RBn).
CRB n clear Remote Bit n (deassert RBn).
PRB n pulse Remote Bit n [assert RBn 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).
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.
