11.5.7.4 Signals from bus-couplerIf the busbar is divided by bus-section disconnectors into bus-sections, the signals BC_12from the busbar coupler of the other busbar section must be transmitted to the own busbarcoupler if both disconnectors are closed.en04000484_ansi.vsdSection 1 Section 2A1A2_DC(BS)B1B2_DC(BS)ABC_BCABC_BC(WA1)A1(WA2)B1(WA7)C CB2A2ANSI04000484 V1 ENFigure 180: Busbars divided by bus-section disconnectors (circuit breakers)The interlocking functionality in 650 series can not handle the transfer bus(WA7)C.To derive the signals:SignalBC_12_CL Another bus-coupler connection exists between busbar WA1 and WA2.VP_BC_12 The switch status of BC_12 is valid.EXDU_BC No transmission error from any bus-coupler bay (BC).These signals from each bus-coupler bay (ABC_BC), except the own bay, are needed:SignalBC12CLTR A bus-coupler connection through the own bus-coupler exists between busbar WA1and WA2.VPBC12TR The switch status of BC_12 is valid.EXDU_BC No transmission error from the bay that contains the above information.These signals from each bus-section disconnector bay (A1A2_DC) are also needed. ForB1B2_DC, corresponding signals from busbar B are used. The same type of module(A1A2_DC) is used for different busbars, that is, for both bus-section disconnectorA1A2_DC and B1B2_DC.1MRK 506 334-UUS A Section 11Control371Application manual
