1448 Auto Close CB2
Signal from autoreclose logic to initiate CB2 close via "CB2 CB Control"
1449 Set CB2 Close
Indicates a CB2 Auto Close signal has been issued
1450 CB2 Control
Output DDB can be applied to inhibit CB2 reclose by adjacent scheme until local autoreclose scheme confirms it is OK to close CB2
1451 CB2 Succ 1P AR
CB2 successful single phase AR
1452 CB2 Succ 3P AR
CB2 successful three phase AR
1453 CB2 Close inProg
CB2 Manual Close initiated – awaiting Man Close Delay time
1454 CB2 Fast SCOK
OK to reclose CB2 with sync check without waiting for dead time to complete
1455 CB2L SCOK
System conditions OK to reclose CB2 as leader when dead time complete
1456 CB2F SCOK
System conditions OK to reclose CB2 when follower time complete
1458 CB2 Man SCOK
System conditions OK to manually close CB2
1459 CB2 Fail Pr Trip
signal to force CB2 AR lockout if CB2 fails to trip when protection operates
1461 Live Bus 2
Indicates Bus 2 input is live, i.e. voltage >= setting [48 89]
1462 Dead Bus 2
Indicates Bus 2 input is dead i.e. voltage < setting [48 8A]
1463 CB2 CS2 OK

permitted for CB1 synchronism check type 2)
1465 CB1 CS2 SlipF<
Line-Bus 1 slip freq < setting [48 98] (frequency difference (slip) between line voltage and bus 1 voltage is within the permitted range
for CB1 synchronism check type 2)
1466 CB2 CS1 SlipF>
Line-Bus 2 slip freq > setting [48 A1] (frequency difference (slip) between line voltage and bus 2 voltage is greater than maximum slip
permitted for CB2 synchronism check type 1)
1467 CB2 CS1 SlipF<
Line-Bus 2 slip freq < setting [48 A1] (frequency difference (slip) between line voltage and bus 2 voltage is within the permitted range
for CB2 synchronism check type 1)
1468 CB2 CS2 SlipF>
Line-Bus 2 slip freq > setting [48 A6] (frequency difference (slip) between line voltage and bus 2 voltage is greater than maximum slip
permitted for CB2 synchronism check type 2)
1469 CB2 CS2 SlipF<
Line-Bus 2 slip freq < setting [48 A6] (frequency difference (slip) between line voltage and bus 2 voltage is within the permitted range
for CB2 synchronism check type 2)
1470 CB2 CS1 VL>VB
Voltage magnitude difference between Line V and Bus2 V is greater than setting [48 9F] (line V > Bus V)
1471 CB2 CS2 VL>VB
Voltage magnitude difference between Line V and Bus2 V is greater than setting [48 A4] (line V > Bus V)
1472 CB2 CS1 VL<VB
Voltage magnitude difference between Line V and Bus2 V is greater than setting [48 9F] (line V < Bus V)
