Command Summary Date Code 970103
SEL-251, -2, -3 Instruction Manual
TARGET R Clears targets and returns to TAR 0
TIME h/m/s Sets or displays time. TIM 13/32/00 sets clock to 1:32:00 PM. IRIG-B synchronization
overrides this setting. To display the time only, enter TIME.
TRIGGER Triggers and saves an event record (event type is EXT).
Access Level 2
CLOSE Closes circuit breaker, if allowed by jumper setting.
COPY m n Copies setting group m to setting group n (m and n equal any combination of 1, 2, 3, 4, 5, or 6).
Clears buffers. If n is the active setting group, the ALARM output contacts pulse closed.
GROUP n Designates the active setting group when no Setting Group Selection Inputs are assigned to
inputs or all Setting Group Selection Inputs assigned to inputs are deasserted (n = 1, 2, 3, 4, 5, or
6). The ALARM output contacts pulse closed when the active group changes. GROUP n
command execution does not clear the event buffer.
OPEN Opens circuit breaker, if allowed by jumper setting.
PASSWORD Shows or sets passwords. ALARM contacts pulse closed after password entry. PAS 1 OTTER
sets Level 1 password to OTTER. PAS 2 TAIL sets Level 2 password to TAIL.
SET n p Initiates setting procedure for setting group n (n = 1, 2, 3, 4, 5, or 6). Option p directs the relay
to begin the setting procedure for setting group n at setting p (e.g., if p = 51P, the setting
procedure starts at setting 51P, bypassing all settings before 51P). If no optional p is entered,
the setting procedure starts at the beginning.
The relay clears event buffers when new settings are stored. If n is the active setting group, the
ALARM output contact pulses closed.
SET G p Initiates setting procedure for the global setting group. Option p directs the relay to begin the
setting procedure for the global setting group at setting p (e.g., if p = TDUR, the setting
procedure starts at setting TDUR, bypassing all settings before TDUR). If optional p is not
used, the setting procedure starts at the beginning.
The SET G command pulses ALARM contacts closed and clears event buffers when new settings
are stored.
