Signal
DCCLTR
The bus-section disconnector is closed.
VPDCTR
The switch status of bus-section disconnector DC is valid.
EXDU_DC
No transmission error from the bay that contains the above information.
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.

Configuration setting
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
