The operate signal of the phase discontinuity protection is connected to the Master Trip and also to an alarm LED and the disturbance recorder. The thermal overload protection (T1PTTR1) provides indication on overload situations. The operate signal of the thermal overload protection is connected to the Master Trip and also to an alarm LED. LED 4 is used for the phase discontinuity protection operate indication, the same as for negative sequence overcurrent protection operate indication, and LED 5 is used for the thermal overload protection alarm indication. The breaker failure protection (CCBRBRF1) is initiated via the start input by a number of different protection stages in the IED. The breaker failure protection function offers different operating modes associated with the circuit breaker position and the measurThe breaker failure protection (CCBRBRF1) is initiated via the start input by a number of different protection stages in the IED. The breaker failure protection function offers different operating modes associated with the circuit breaker position and the measured phase and residual currents. The breaker failure protection has two operating outputs: TRRET and TRBU. The TRRET operate output is used for retripping its own breaker through the Master Trip 2. The TRBU output is used to give a back-up trip to the breaker feeding upstream. For this purpose, the TRBU operate output signal is connected to the output PO2 (X100: 8-9). LED 6 is used for back-up (TRBU) operate indication. 1MRS756378 K Section 3 REF615 standard configurations REF615 85 Application Manual PHHPTOC2-operate PHHPTOC1-operate PHIPTOC1-operate OR ARC PROTECTION (Optional) LED10 (ARC PROTECTION) ARCSARC1-operate ARCSARC2-operate ARCSARC3-operate AUTORECLOSING (Optional) OR PDNSPTOC1-operate NSPTOC1-operate NSPTOC2-operate CBXCBR1-selected LED11 (AR IN PROGRESS) X110 6 7 X120_BI3 (CB Open) BI4 (CB Spring Charged) DARREC1 0 -> 1 79 INIT_1 INIT_2 INIT_3 INIT_4 INIT_5 INIT_6 DEL_INIT_2 DEL_INIT_3 DEL_INIT_4 BLK_RECL_T BLK_RCLM_T BLK_THERM CB_POS CB_READY INC_SHOTP INHIBIT_RECL RECL_ON SYNC OPEN_CB CLOSE_CB CMD_WAIT INPRO LOCKED PROT_CRD UNSUC_RECL AR_ON READY ARCSARC1 ARC (1) 50L/50NL (1) 3I Io BLOCK REM_FLT_ARC OPR_MODE OPERATE ARC_FLT_DET ARCSARC2 ARC (2) 50L/50NL (2) 3I Io BLOCK REM_FLT_ARC OPR_MODE OPERATE ARC_FLT_DET ARCSARC3 ARC (3) 50L/50NL (3) 3I Io BLOCK REM_FLT_ARC OPR_MODE OPERATE ARC_FLT_DET EFLPTOC1-operate EFHPTOC1-operate X110_BI2 (AR ext.
