Figure 167: Signals to a line bay in section 1 from the bus-coupler bays in each section
For a line bay in section 2, the same conditions as above are valid by changing section 1 to
section 2 and vice versa.
15.4.2.4 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
• QC71_OP = 1
• QC71_CL = 0
