EXDUP_BC
Signal if there is no transmission error from bay BC (bus-coupler bay).
See "Signals from bus coupler" on page 112.
If there is no second busbar B and therefore no Q2 disconnector, then the
interlocking for Q2 is not used. The state for Q2, Q25, BC_AB are set to
open by setting the appropriate module inputs as follows. In the functional
block diagram, 0 and 1 are designated 0=FIXD-OFF and 1=FIXD-ON:
• Q2_OP = 1
• Q2_CL = 0
• Q25_OP = 1
• Q25_CL = 0
• BC_AB_CL = 0
If there is no second busbar B at the other side of the transformer and
therefore no TQ2 disconnector, then the state for TQ2 is set to open by
setting the appropriate module inputs as follows:
• TQ2_OP = 1
• TQ2_CL = 0
For a double, circuit-breaker bay, the modules DB_BUS_A, DB_LINE
and DB_BUS_B must be used.
For a breaker-and-a-half arrangement, the modules BH_LINE_A,
BH_CONN and BH_LINE_B must be used.
For application without Q9 and Q8, just set the appropriate inputs to open
state and disregard the outputs. In the functional block diagram, 0 and 1
are designated 0=FIXD-OFF and 1=FIXD-ON:
• Q9_OP = 1
• Q9_CL = 0
• Q8_OP = 1
• Q8_CL = 0
If, in this case, a line voltage supervision is added, then rather than setting
Q9 to open state, specify the state of the voltage supervision:
• Q9_OP = VOLT_OP
• Q9_CL = VOLT_CL
