12.4.2.4 Configuration setting
If there is no bypass busbar and therefore no 789 disconnector, then the interlocking for 789 is not used.
The states for 789, 7189G, BB7_D, BC_17, BC_27 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:
• 789_OP = 1
• 789_CL = 0
• 7189G_OP = 1
• 7189G_CL = 0
• BB7_D_OP = 1
• BC_17_OP = 1
• BC_17_CL = 0
• BC_27_OP = 1
• BC_27_CL = 0
• EXDU_BPB = 1
• VP_BB7_D = 1
• VP_BC_17 = 1
• VP_BC_27 = 1
If there is no second busbar WA2 and therefore no 289 disconnector, then the interlocking for 289 is not
used. The state for 289, 2189G, BC_12, BC_27 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
• 2189G_OP = 1
• 2189G_CL = 0
• BC_12_CL = 0
• BC_27_OP = 1
• BC_27_CL = 0
• VP_BC_12 = 1
12.4.3 Interlocking for bus-coupler bay ABC_BC (3)
12.4.3.1 Application
The interlocking for bus-coupler bay (ABC_BC, 3) function is used for a bus-coupler bay connected to a
double busbar arrangement according to figure 154. The function can also be used for a single busbar
arrangement with transfer busbar or double busbar arrangement without transfer busbar.
