M13560-108 v4
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
