Figure 177: Signals from any bays in bus-coupler bay n
If the busbar is divided by bus-section disconnectors into bus-sections, the signals BBTR
are connected in parallel - if both bus-section disconnectors are closed. So for the basic
project-specific logic for BBTR above, add this logic:

The interlocking functionality in 650 series cannot handle the transfer bus
(WA7)C.
The following signals from each bus-section disconnector bay (A1A2_DC) are needed.
For B1B2_DC, corresponding signals from busbar B are used. The same type of module
