BH_LINE_B) functions are used for lines connected to a 1 1/2 breaker diameter
according to figure 85.

Figure 85: Switchyard layout 1 1/2 breaker
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:
