SEL-351 Instruction Manual
STA Show relay self-test status.
TAR R Reset front-panel tripping targets.
TAR n k Display Relay Word row. If n = 0 – 45, 49, or 53 (depending on firmware version), 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).
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 Trigger an event report.
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 wear. 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 RBn (Remote Bit n; n = 1 – 8). 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).
LOO
1
p t Set MIRRORED BITS port p to loopback (p = A or B). The received MIRRORED BITS elements
are forced to default values during the loopback test; t specifies the loopback duration in
minutes (t = 1 – 5000, default is 5).
LOO
1
p DATA Set MIRRORED BITS port p to loopback. DATA allows the received MIRRORED BITS elements
to change during the loopback test.
PAS Show existing Access Level 1, Level B, and Level 2 passwords.
PAS 1 xxxxxx Change Access Level 1 password to xxxxxx.
PAS B xxxxxx Change Access Level B password to xxxxxx.
PAS 2 xxxxxx Change Access Level 2 password to xxxxxx.
Entering DISABLE as the password disables the password requirement for the specified
access level.
