Appendix B - Settings and Signals
ORDINAL
To enable SOTF logic by an external pulse. When this input is energized by en external pulse, SOTF becomes enabled during "SOTF Pulse"
time setting
509 RP1 Read Only
Enables RP1 Read Only
510 RP2 Read Only
Enables RP2 Read Only
511 NIC Read Only
Enables NIC Read Only
522 Any Trip
Any trip signal - can be used as the trip command in three-pole tripping applications
523 Trip Output A
Trip signal for phase A - used as a command to drive trip A output contact(s). Takes the output from the internal trip conversion logic
524 Trip Output B
Trip signal for phase B - used as a command to drive trip B output contact(s). Takes the output from the internal trip conversion logic
525 Trip Output C
Trip signal for phase C - used as a command to drive trip C output contact(s). Takes the output from the internal trip conversion logic
526 Trip 3ph
Trip signal for 3ph - used as a command to drive trip 3ph output contact(s). Takes the output from the internal trip conversion logic
527 2/3 Ph Fault
2 or 3 phase fault indication - used to flag whether the fault is polyphase. Typically used to control auto-reclose logic, where auto-reclosing
is allowed only for single phase faults
528 3 Ph Fault
3 phase fault indication. Typically used to control auto-reclose logic, where auto-reclosing is blocked for faults affecting all three phases
together
528 3 Ph Fault
3 phase fault indication. Typically used to control auto-reclose logic, where auto-reclosing is blocked for faults affecting all three phases
together
529 Trip Inputs 3Ph
Trip 3 phase - input to trip latching logic
530 Trip Inputs A
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
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
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 3Pole Trip
External DDB input to host protection trip conversion logic to force 3 Pole tripping of CB for all faults
534 External Trip3ph
External trip 3 phase - allows external protection to initiate breaker fail, circuit breaker condition monitoring statistics, and internal auto-
reclose (if enabled)
535 External Trip A
External trip A phase - allows external protection to initiate breaker fail, circuit breaker condition monitoring statistics, and internal auto-
reclose (if enabled)
536 External Trip B
External trip B phase - allows external protection to initiate breaker fail, circuit breaker condition monitoring statistics, and internal auto-
reclose (if enabled)
537 External Trip C
External trip C phase - allows external protection to initiate breaker fail, circuit breaker condition monitoring statistics, and internal auto-
reclose (if enabled)
542 SG Select 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
Setting group selector 1X (high bit)-selects SG3 if only DDB 543 is active.
