SEL-400 Series Relays Instruction Manual Date Code 20171006
ASCII Command Reference
Command Description
If the circuit breaker control enable jumper BREAKER is not in place, the relay
aborts the command and responds,
Aborted: the breaker jumper is not
installed
.
When you issue the PUL command and the breaker jumper is in place, the relay
responds,
Pulse contact OUTnnn for s seconds (Y/N)?. If you answer
Y <Enter>, the relay asserts OUTnnn for the time you specify.
During the PUL operation, the Relay Word bit corresponding to the control out-
put you specified (OUTnnn) asserts; Relay Word bit TESTPUL also asserts
during any PUL command, so you can monitor pulse operation by programming
TESTPUL into event triggers and alarm outputs.
QUIT
Use the QUIT command to revert to Access Level 0 (exit relay control).
Access Level 0 is the lowest access level; the relay performs no password check
to descend to this level (or remain at this level).
In a Telnet session, QUIT terminates the connection.
RTC
Use the RTC command to display a description of all data being received on syn-
chrophasor client channels. This report will list the analog quantity and Relay
Word bits the data gets stored in locally, matched up with a label provided by the
sending PMU. Use this information as aid to understanding the local values.
NOTE: Not all SEL-400 series relays
support synchrophasors.
SER
The SER command retrieves SER records. The relay SER captures state changes
of Relay Word bit elements and relay conditions. Relay conditions include
startup, relay enable/disable, group changes, settings changes, memory queue
overflow, and SER autoremoval/reinsertion. For more information on the SER,
see Sequential Events Recorder (SER) on page 9.28.
