IEC04000513 V1 EN-US
Figure 130:
Three types of interlocking modules per diameter are defined. BH_LINE_A and BH_LINE_B are the
connections from a line to a busbar. BH_CONN is the connection between the two lines of the
diameter in the 1 1/2 breaker switchyard layout.
For a 1 1/2 breaker arrangement, the modules BH_LINE_A, BH_CONN and BH_LINE_B must be
used.

Configuration setting
For application without QB9 and QC9, just set the appropriate inputs to open state and disregard the
outputs. In the functional block diagram, 0 and 1 are designated 0=FALSE and 1=TRUE:
•
QB9_OP = 1
•
QB9_CL = 0
•
QC9_OP = 1
•
QC9_CL = 0
If, in this case, line voltage supervision is added, then rather than setting QB9 to open state, specify
the state of the voltage supervision:
•
QB9_OP = VOLT_OFF
•
QB9_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
•
VOLT_OFF = 1
•
VOLT_ON = 0
