Figure 144: Signals to a bus-coupler bay in section 1 from a bus-coupler bay in another
For a bus-coupler bay in section 2, the same conditions as above are valid by changing section 1 to
section 2 and vice versa.
14.4.3.5 Configuration setting
If there is no bypass busbar and therefore no 289 and 789 disconnectors, then the interlocking for
289 and 789 is not used. The states for 289, 789, 7189G 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
• 789_OP = 1
• 789_CL = 0
• 7189G_OP = 1
• 7189G_CL = 0
If there is no second busbar B and therefore no 289 and 2089 disconnectors, then the interlocking
for 289 and 2089 are not used. The states for 289, 2089, 2189G, BC_12, BBTR 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
• 2089_OP = 1
• 2089_CL = 0
• 2189G_OP = 1
• 2189G_CL = 0
• BC_12_CL = 0
• VP_BC_12 = 1
