Configuration setting

If there is no bypass busbar and therefore no QB7 disconnector, then the interlocking for QB7
is not used. The states for QB7, QC71, BB7_D, BC_17, BC_27 are set to open by setting the
appropriate module inputs as follows. In the functional block diagram, 0 and 1 are designated
0=FALSE and 1=TRUE:
• QB7_OP = 1
• QB7_CL = 0
