The EAFR-101S logic Configuration 4 is used as the inter-
mediate unit. Sensors are monitoring the section circuit
breaker and the busbar between the section circuit breaker.
BI3 and BI4 receive over-current information from the two
main busbar sections respectively. BO1 and BO3 represent
the arc fault detected at both main busbar sections.
