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.
12.4.3.5
Configuration setting
If there is no bypass busbar and therefore no QB2 and QB7 disconnectors, then the interlocking for
QB2 and QB7 is not used. The states for QB2, QB7, QC71 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:
•
QB2_OP = 1
•
QB2_CL = 0
•
QB7_OP = 1
•
QB7_CL = 0
•
QC71_OP = 1
•
QC71_CL = 0
If there is no second busbar B and therefore no QB2 and QB20 disconnectors, then the interlocking
for QB2 and QB20 are not used. The states for QB2, QB20, QC21, 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:
•
QB2_OP = 1
•
QB2_CL = 0
•
QB20_OP = 1
•
QB20_CL = 0
•
QC21_OP = 1
•
QC21_CL = 0
•
BC_12_CL = 0
•
VP_BC_12 = 1
•
BBTR_OP = 1
•
VP_BBTR = 1
