233 A/R TPAR Enable
Three pole autorecloser (TPAR) activated: If it is
assigned to an opto input in the PSL (by default, the PSL
is inverted and linked to opto 8) and energized, the
DDB:'A/R TPAR Enable' will enable the 3-pole
autoreclose logic (the priority is higher than the 'CB
Control / A/R three pole' setting) - this means the 3-pole
autoreclose logic can be disabled even if it has been
activated; if the relevant opto input is not energised (to
be valid, the opto input must be energised for over 1.2s).
NOTE: After a new PSL has been downloaded to the
relay (including the "TPAR" or "SPAR" cells); the
settings configuration must be uploaded back (from PC
to relay) to update the data in the RAM and the
EEPROM (otherwise discrepancies could appear in the
“AR enable” logic sate).
Set to 1: 3P AR activated (copy of 'TPAR enable' opto
input OR 'CB Control/ A/R Three pole' enabled)
Reset to 0: if 'TPAR enable' = 0 OR ('A/R Three pole'
disabled)

Autorecloser
234 A/R Lockout
Autorecloser locked-out (no autoreclosure possible until
reset),
If protection operates during the reclaim time, after the
final reclose attempt, the relay will be driven to lockout
and the autoreclose function will be disabled until the
lockout condition is reset. This will produce an alarm:
A/R Lockout. Then, the DDB:'BAR' input will block the
autorecloser and cause a lockout if a reclose cycle is in
progress. Lockout will also occur if the CB energy is low
and the CB fails to close. Once the autorecloser is
locked out, it will not function until a Reset Lockout or
CB Manual Close command is received (depending on
the Reset Lockout method chosen in CB Monitor Setup).
NOTE: Lockout can also be caused by the CB condition
monitoring functions maintenance lockout, excessive
fault frequency lockout, broken current lockout, CB failed
to trip and CB failed to close, manual close no check
synchronism and CB unhealthy.

Force synchronism check to be made (simulate the
CheckSync control and forces the DDB:'CheckSync OK'

autoreclose cycle)
