disconnector or breaker truck and earth-switch position status, status of the trip logics,gas pressure alarm and circuit-breaker spring charging status.The OKPOS output from DCSXSWI defines whether the disconnector or breakertruck is either open (in test position) or close (in service position). This output,together with the open earth-switch and non-active trip signals, activates the close-enable signal to the circuit breaker control function block. The open operation forcircuit breaker is always enabled.The SYNC_ITL_BYP input can be used, for example, to always enable the closing ofthe circuit breaker when the circuit breaker truck is in the test position.SYNC_ITL_BYP overrides, for example, active interlocking conditions when thecircuit breaker truck is closed in service position.CBXCBR1POSOPENPOSCLOSEENA_OPENENA_CLOSEBLK_OPENBLK_CLOSEAU_OPENAU_CLOSETRIPSYNC_OKSYNC_ITL_BYPSELECTEDEXE_OPEXE_CLOP_REQCL_REQOPENPOSCLOSEPOSOKPOSOPEN_ENADCLOSE_ENADTRUEX120_BI3_CB_OPENEDX120_BI2_CB_CLOSEDCBXCBR1_ENA_CLOSECBXCBR1_EXE_CLCBXCBR1_EXE_OPFALSECBXCBR1_AU_OPENCBXCBR1_AU_CLOSECBXCBR1_SELECTEDGUID-54C9EDF5-8EE3-4C65-85A8-D098A2EC7326 V2 ENFigure 79: Circuit-breaker control logic: Circuit breaker 1Connect the additional signals required for the application for closingand opening of circuit breaker.ORB1B2O CB_CLOSE_COMMANDCBXCBR1_EXE_CLDARREC1_CLOSE_CBGUID-CBE9421A-1896-448B-903A-86C63FAC47E9 V1 ENFigure 80: Circuit-breaker control logic: Signals for closing coil of circuit breakerOR6B1B2B3B4B5B6O CB_OPEN_COMMANDCBXCBR1_EXE_OPTRPPTRC1_TRIPDARREC1_OPEN_CBGUID-E3C59277-527E-48D1-9815-0E1416827C6F V1 ENFigure 81: Circuit-breaker control logic: Signals for opening coil of circuitbreakerSection 3 1MRS756378 SREF615 standard configurations90 REF615Application Manual
