Instruction Manual SEL-351A Relay
SEL-351A Command Summary
Access Level 0
Command Access Level 0 is the initial relay access level. The relay automatically returns to Access Level 0
when a serial port time-out setting expires or after a QUIT command. The screen prompt is:
=
ACC Enter Access Level 1. If the main board password jumper is not in place, the relay prompts the user for the
Access Level 1 password in order to enter Access Level 1.
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:
=>
2AC Enter Access Level 2. If the main board password jumper is not in place, the relay prompts for the entry of the
Access Level 2 password in order to enter Access Level 2.
BAC Enter Breaker Access Level (Access Level B). If the main board password jumper is not in place, the relay
prompts the user for the Access Level B password.
BRE Display breaker monitor data (trips, interrupted current, wear).
DAT Show date.
DAT mm / dd / yy Enter date in this manner if global Date Format setting, DATE_F, is set to MDY.
DAT yy / mm / dd Enter date in this manner if global Date Format setting, DATE_F, is set to YMD.
EVE n Show event report n with 4 samples per cycle ( n = 1 to highest numbered event report, where 1 is the most recent
report: see HIS command). If n is omitted, ( EVE command) most recent report is displayed.
EVE n A Show event report n with analog section only.
EVE n C Show event report n in Compressed ASCII format for use with the SEL-5601 Analytic Assistant.
EVE n D Show event report n with digital section only.
EVE n L Show event report n with 16 samples per cycle (similar to EVE n S16 ).
EVE n L y Show first y cycles of event report n ( y = 1 to global setting LER).
EVE n P Show event report n with synchrophasor-level accuracy time alignment.
EVE n R Show event report n in raw (unfiltered) format with 16 samples per cycle resolution.
EVE n S x Show event report n with x samples per cycle ( x = 4 or 16).
EVE n V Show event report n with variable scaling for analog values.
GRO Display active group number.
HIS n Show brief summary of n latest event reports, where 1 is the most recent entry. If n is not specified,
( HIS command) all event summaries are displayed.
HIS C Clear all event reports from nonvolatile memory.
IRI Force synchronization attempt of internal relay clock to IRIG-B time-code input.
MET k Display instantaneous metering data. Enter k for repeat count ( k = 1–32767, if not specified, default is 1).
MET D Display demand and peak demand data. Select MET RD or MET RP to reset.
MET E Display energy metering data. Select MET RE to reset.
MET M Display maximum/minimum metering data. Select MET RM to reset.
MET PM [ time ]
[ k ]
Display synchrophasor measurements (available when TSOK = logical 1). Enter time to display the synchropha-
sor for an exact specified time, in 24-hour format. Enter k for repeat count.
MET X k Display same data as MET command with phase-to-phase voltages. Enter k for repeat count ( k = 1–32767, if not
specified default is 1).
QUI Quit. Returns to Access Level 0. Terminates SEL Distributed Port Switch Protocol (LMD) connection.
SER Show entire Sequential Events Recorder (SER) report.
SER d1 Show all rows in the SER report recorded on the specified date (see DAT command for date format).
