Appendix B - Settings and Signals
ORDINAL
DDB mapped in PSL from opto input (Bus VT secondary MCB tripped or VT fail detected by external VTS scheme), or signal from host relay VTS
scheme
1522 Inhibit LL
DDB mapped in PSL from opto input (external signal to inhibit Live Line function)
1523 Inhibit DL
DDB mapped in PSL from opto input (external signal to inhibit Dead Line function)
1524 Inhibit LB
DDB mapped in PSL from opto input (external signal to inhibit Live Bus function)
1525 Inhibit DB
DDB mapped in PSL from opto input (external signal to inhibit Dead Bus function)
1526 CB In Service
CB In Service (can be initiated for autoreclose)
1528 CB NoAR
CB not available for autoreclose
1535 Trip AR MemA
A Ph trip & AR initiation memory
1536 Trip AR MemB
B Ph trip & AR initiation memory
1537 Trip AR MemC
C Ph trip & AR initiation memory
1541 AR Start
Any AR initiation signal present
1542 ARIP
Any AR cycle in progress
1543 AR Initiation
CB AR cycle initiation
1544 CB ARIP
CB AR cycle in progress
1546 Seq Counter>Set
Sequence counts greater than AR Shots settings
1547 Evolve 3Ph
If a single phase fault evolves to a multi-phase fault during the single phase dead time, this DDB indicates the fault has evolved and that
SPAR will be stopped and 3PAR started.
1550 CB Failed AR
CB AR failed due to persistent fault
1551 DTOK All
Enabling condition for any dead time
1552 DTOK CB 1P
Output DDB indicates conditions to enable single phase autoreclose dead time to run are satisfied
1553 DTOK CB 3P
Output DDB indicates conditions to enable three phase autoreclose dead time to run are satisfied
1554 1P DTime
Indicates single phase autoreclose dead time running
1555 OK Time 3P
OK to start 3PAR dead time
1556 3P DTime1
3Phase dead time 1 running
1557 3P DTime2
3Phase dead time 2 running
1558 3P DTime3
3Phase dead time 3 running
1559 3P DTime4
3Phase dead time 4 running
1560 3P Dtime
Indicates three phase autoreclose dead time running
1565 Set CB Close
Indicates Auto Close signal has been issued
1566 CB Control
