ABB RET670 Applications Manual

The signals from other bays connected to the module ABC_LINE (3) are described below.
Signals from bypass busbar
To derive the signals:
Signal
BB7_D_OP All line disconnectors on bypass WA7 except in the own bay are open.
VP_BB7_D The switch status of disconnectors on bypass busbar WA7 are valid.
EXDU_BPB No transmission error from any bay containing disconnectors on bypass busbar WA7
These signals from each line bay (ABC_LINE, 3) except that of the own bay are needed:
Signal
789OPTR 789 is open
VP789TR The switch status for 789 is valid.
EXDU_BPB No transmission error from the bay that contains the above information.
For bay n, these conditions are valid:
