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:

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
