Signal
BC12CLTR
A bus-coupler connection through the own bus-coupler exists between busbar
WA1 and WA2.
BC17OPTR
No bus-coupler connection through the own bus-coupler between busbar WA1
and WA7.
BC17CLTR
A bus-coupler connection through the own bus-coupler exists between busbar
WA1 and WA7.
BC27OPTR
No bus-coupler connection through the own bus-coupler between busbar WA2
and WA7.
BC27CLTR
A bus-coupler connection through the own bus-coupler exists between busbar
WA2 and WA7.
VPBC12TR
The switch status of BC_12 is valid.
VPBC17TR
The switch status of BC_17 is valid.
VPBC27TR
The switch status of BC_27 is valid.
EXDU_BC
No transmission error from the bay that contains the above information.
These signals from each bus-section disconnector bay (A1A2_DC) are also needed. For
B1B2_DC, corresponding signals from busbar B are used. The same type of module (A1A2_DC)
is used for different busbars, that is, for both bus-section disconnector A1A2_DC and B1B2_DC.
Signal
DCOPTR
The bus-section disconnector is open.
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
S1S2OPTR
No bus-section coupler connection between bus-sections 1 and 2.
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 that contains the above information.
For a line bay in section 1, these conditions are valid:
