If the busbar is divided by bus-section circuit breakers, the signals from the bus-section
coupler bay (A1A2_BS), rather than the bus-section disconnector bay (A1A2_DC),
must be used. For B1B2_BS, corresponding signals from busbar B are used. The same
type of module (A1A2_BS) is used for different busbars, that is, for both bus-section
circuit breakers A1A2_BS and B1B2_BS.
Signal
S1S2CLTR A bus-section coupler connection exists between bus sections 1 and 2.
VPS1S2TR The switch status of bus-section coupler BS is valid.
EXDU_BS No transmission error from the bay containing the above information.
For a bus-coupler bay in section 1, these conditions are valid:

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.

If there is no bypass busbar and therefore no 289 and 789 disconnectors, then the
interlocking for 289 and 789 is not used. The states for 289, 789, 7189G 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:
• 289_OP = 1
• 289_CL = 0
• 789_OP = 1
• 789_CL = 0
