For a bus-coupler bay in section 1, these conditions are valid:

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.

If there is no bypass busbar and therefore no Q20 and Q7 disconnectors, then the inter-
locking for Q20 and Q7 is not used. The states for Q20, Q7, Q75, BC_AB are set to
open by setting the appropriate module inputs as follows. In the functional block dia-
gram, 0 and 1 are designated 0=FIXD-OFF and 1=FIXD-ON:
•
Q20_OP = 1
•
Q20_CL = 0
•
Q7_OP = 1
•
Q7_CL = 0

A1A2CLTR
Signal if a bus-section coupler connection exists between bus sections A1
and A2.
VPA1A2TR
The switch status of Q0, Q11 and Q12 are valid.
EXDUP_BS
Signal if no transmission error from the bay containing the above informa-
tion. This signal is taken from the data valid output on the command func-
tion block.
