Signal if there is no transmission error from the bay that contains the
above information. This signal is taken from the data valid output on the
command function block.
For a bus-coupler bay in section 1, these conditions are valid:
BBTR_OP (sect.1)
DCOPTR (A1A2)
DCOPTR (B1B2)
BBTR_OP (sect.2)
VP_BBTR (sect.1)
VPDCTR (A1A2)
VPDCTR (B1B2)
VP_BBTR (sect.2)
EXDUP_AB (sect.1)
EXDUP_DC (A1A2)
EXDUP_DC (B1B2)
EXDUP_AB (sect.2)
Fig. 16 Signals to a bus-coupler bay in section 1 from any bays in each
section
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 the busbar is divided by bus-section disconnectors into bus sections, the
signals BC_AB from the busbar coupler of the other busbar section must
be transmitted to the own busbar coupler if both disconnectors are closed.
