Up to five reclosing attempts can be included by parameter setting. The first attempt canbe single- and/or three phase for single-phase or multi-phase faults respectively.Multiple autoreclosing functions are provided for multi-breaker arrangements. A prioritycircuit allows one circuit breaker to close first and the second will only close if the faultproved to be transient.The autoreclosing function is configured to co-operate with the synchrocheck function.11.3.3 Function blockSTBRREC (79)ONOFFBLKONBLKOFFRESETINHIBITPICKUPTRSOTFZONESTEPTR3PTHOLHOLDCBREADY52APLCLOSTSYNCWAITRSTCOUNTBLOCKEDSETONREADYACTIVESUCCLUNSUCCLINPROGR1PT13PT13PT23PT33PT43PT5PREP3PCLOSECMDWFMASTERCOUNT1PCOUNT3P1COUNT3P2COUNT3P3COUNT3P4COUNT3P5COUNTARANSI10000218-1-en.vsdANSI10000218 V1 ENFigure 177: STBRREC (79) function block11.3.4 SignalsTable 248:STBRREC (79) Input signalsName Type Default DescriptionON BOOLEAN 0 Enables AR when Operation = ExternalCtrlOFF BOOLEAN 0 Disables AR when Operation = ExternalCtrlBLKON BOOLEAN 0 Sets AR in blocked stateBLKOFF BOOLEAN 0 Releases AR from blocked stateRESET BOOLEAN 0 Resets AR to initial conditionsINHIBIT BOOLEAN 0 Interrupts and inhibits reclosing sequencePICKUP BOOLEAN 0 Reclosing sequence starts by a protection trip signalTable continues on next pageSection 11 1MRK 506 335-UUS AControl376Technical manual
