Logic Inputs / outputs used by the Autoreclose logic

5.10.2.1 Logic inputs used by the Autoreclose logic
Contacts from external equipment (External protection or external Check Synchronism or
external Autoreclose) may be used to influence the autorecloser via opto-isolated inputs.
Such functions can be allocated to any of the opto-isolated inputs on the relay via the
programmable scheme logic (Ensure that optos1&2 are not set for setting group change-
Otherwise, these opto inputs cannot be mapped to functions in the PSL. The inputs can be
selected to accept either a normally open or a normally closed contact, programmable via
the PSL editor (see section P44x/EN PL for complete description).
• A/R SPAR Enable (the opto input must be be energised for over 1.2 s),
• A/R TPAR Enable (the opto input must be energised for over 1.2 s),
Note:
• A/R Internal
• I A/R 1p In Prog (internal autoreclose single-pole in progress)
• I A/R 3p In Pr. (internal autoreclose three-pole in progress)
• I A/R Close (Circuit Breaker closing order from external autoreclose)
• I A/R Reclaim (Autoreclose in reclaim)
• BAR (Block internal Autoreclose)
• Ext Chk Synch OK (external check synchronisation OK),
• Force 3P trip
• Man. Close CB (circuit breaker manual close)
• Man. Trip CB (circuit breaker manual trip),
• CB Discrepancy
• External Trip A, External Trip B and External Trip C

5.10.2.2 Logic outputs generated by the Autoreclose logic

The following DDB signals can be masked to a relay contact in the PSL or assigned to a
Monitor Bit in Commissioning Tests, to provide information about the autoreclose cycle
status. They are described below, and identified by their DDB signal label (see section
P44x/EN PL for complete description).
• A/R 1P In Prog,
• A/R 234 in Prog,
• A/R Close,
• A/R Enable,
• A/R Fail,
• A/R first in Prog.,
• A/R Force Sync,
• A/R Lockout,
• A/R Reclaim,
• A/R SPAR Enable,
• A/R TPAR Enable,
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
"A/R enable" logic sate).
