Figure 93: Signals to a bus-coupler bay in section 1 from a bus-coupler bay in
another section
For a bus-coupler bay in section 2, the same conditions as above are valid by
changing section 1 to section 2 and vice versa.
12.4.3.5 Configuration setting
M13553-107 v4
If there is no bypass busbar and therefore no QB2 and QB7 disconnectors, then the
interlocking for QB2 and QB7 is not used. The states for QB2, QB7, QC71 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:
• QB2_OP = 1
• QB2_CL = 0
• QB7_OP = 1
• QB7_CL = 0
• QC71_OP = 1
• QC71_CL = 0
If there is no second busbar B and therefore no QB2 and QB20 disconnectors, then
the interlocking for QB2 and QB20 are not used. The states for QB2, QB20, QC21,
BC_12, BBTR 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:
• QB2_OP = 1
• QB2_CL = 0
• QB20_OP = 1
• QB20_CL = 0
• QC21_OP = 1
• QC21_CL = 0
