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:

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:

2189G_OP = 1

2189G_CL = 0

BC_12_CL = 0

BC_27_OP = 1

BC_27_CL = 0

VP_BC_12 = 1
