Figure 335: Busbars divided by bus-section disconnectors (circuit breakers)
The project-specific logic for input signals concerning bus-coupler are the same as the
specific logic for the line bay (ABC_LINE):
Signal
BC_12_CL A bus-coupler connection exists between busbar WA1 and WA2.
VP_BC_12 The switch status of BC_12 is valid.
EXDU_BC No transmission error from bus-coupler bay (BC).
The logic is identical to the double busbar configuration “Signals from bus-coupler“.
15.4.4.3 Configuration setting
If there are no second busbar B and therefore no 289 disconnector, then the interlocking
for 289 is not used. The state for 289, 2189G, BC_12 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
• 289QB2_CL = 0
• 2189G_OP = 1
• 2189G_CL = 0
• BC_12_CL = 0
• VP_BC_12 = 1
