DESCRIPTION
529
CB1 Trip I/P 3Ph
DDB_TR_3_PHASE
CB1 Trip 3 Phase - Input to Trip Latching Logic
530
Trip Inputs A
DDB_TR_A_PHASE
A phase trip - input to trip conversion logic. Essential to ensure correct single or three pole trip command results (e.g. converts a 2
pole trip to 3 phase)
531
Trip Inputs B
DDB_TR_B_PHASE
B phase trip - input to trip conversion logic. Essential to ensure correct single or three pole trip command results (e.g. converts a 2
pole trip to 3 phase)
532
Trip Inputs C
DDB_TR_C_PHASE
C phase trip - input to trip conversion logic. Essential to ensure correct single or three pole trip command results (e.g. converts a 2
pole trip to 3 phase)
533
Force 3PTrip CB1
DDB_FORCE_3_POLE_TRIP
External DDB input to host protection trip conversion logic to force 3 Pole tripping of CB1 for all faults
534
CB1 Ext Trip3ph
DDB_EXTERNAL_TRIP_3PH
CB1 Ext Trip3ph - signal from external protection to initiate three phase autoreclosing of CB1
535
CB1 Ext Trip A
DDB_EXTERNAL_TRIP_A
CB1 Ext Trip A - signal from external protection to initiate single phase autoreclosing (A Ph) of CB1
536
CB1 Ext Trip B
DDB_EXTERNAL_TRIP_B
CB1 Ext Trip B - signal from external protection to initiate single phase autoreclosing (B Ph) of CB1
537
CB1 Ext Trip C
DDB_EXTERNAL_TRIP_C
CB1 Ext Trip C - signal from external protection to initiate single phase autoreclosing (C Ph) of CB1
538
CB2 Ext Trip3ph
DDB_CB2_EXTERNAL_TRIP_3PH
External trip 3 phase - allows external protection to initiate breaker 2 fail
539
CB2 Ext Trip A
DDB_CB2_EXTERNAL_TRIP_A
External trip A phase - allows external protection to initiate breaker 2 fail
540
CB2 Ext Trip B
DDB_CB2_EXTERNAL_TRIP_B
External trip B phase - allows external protection to initiate breaker 2 fail
541
CB2 Ext Trip C
DDB_CB2_EXTERNAL_TRIP_C
External trip C phase - allows external protection to initiate breaker 2 fail
542
SG Select x1
DDB_SG_SELECTOR_X1
Setting group selector X1 (low bit)-selects SG2 if only DDB 542 signal is active.
SG1 is active if both DDB 542 & DDB 543=0
SG4 is active if both DDB 542 & DDB 543=1
543
SG Select 1x
DDB_SG_SELECTOR_1X
Setting group selector 1X (high bit)-selects SG3 if only DDB 543 is active.
SG1 is active if both DDB 542 & DDB 543=0
SG4 is active if both DDB 542 & DDB 543=1
544
Clear Statistics
DDB_CLEAR_STATISTICS
To reset all statistics values cumulated on the relay. If mapped, the input for this signal could come from a command of the remote
end (DDB 1020 - clear stats cmd -) via IM64
550
