SS:4
The logic scheme SS:4 is used as an intermediate unit. The sensors monitor the section circuit breaker
and the busbar within the section circuit breaker. The binary inputs BI3 and BI4 receive overcurrent
information from two main busbar sections (BI3 from one of them, BI4 from the other). The binary
outputs BO1 and BO3 represent the arc fault detected at both main busbar sections.
You can find a more detailed description of this scheme in the AQ-SAS

booklet.
