1MRK 505 287-UUS B
10.3.7.5 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
• BBTR_OP = 1
• VP_BBTR = 1
10.3.8 Interlocking for breaker-and-a-half diameter BH (3)
10.3.8.1 Application
The interlocking for breaker-and-a-half diameter (BH_CONN(3), BH_LINE_A(3), BH_LINE_B(3))
functions are used for lines connected to a breaker-and-a-half diameter according to figure 86.
