Application
M13570-3 v6
The interlocking for 1 1/2 breaker diameter (BH_CONN, BH_LINE_A, BH_LINE_B) functions are
used for lines connected to a 1 1/2 breaker diameter according to figure
.

M13570-7 v4
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.
M13569-4 v4
For a 1 1/2 breaker arrangement, the modules BH_LINE_A, BH_CONN and BH_LINE_B must be
used.

Configuration setting
M13569-6 v5
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
