Current inputs Phase IL1, IL2, IL3 and E/F Io, measuring current for
incomer.
Receive L> light signal from connected AQ110P
Receive L> light signal from connected AQ101.
In scheme 1a, 2a, it counts the amount of connected AQ101 units while
supervising each BO1 connections from AQ101 units.
In scheme 1b, it excludes the counting function and triggers the
supervision alarm (SF relay) when loss of all connected AQ101 units.
Detect arc flash light for incomer cable compartment.
