This section describes the available configurations that are
available using the Configuration Select 1 through 4 dip-
switches.
3.5.1.1 Configuration Selection 0
The EAFR-101 logic Configuration 0 can be not only applied
as stand-alone arc protection relay, but also widely used
as non-selective outgoing feeder compartment protection.
Dependent on this configuration, the user can select either
light only mode or arc light + over-current mode to trip all
circuit breakers. The detailed instruction is described in

The EAFR-101 logic Configuration 1 is mainly utilized in
selective arc protection solutions. The point sensor S1
monitors the outgoing feeder cable compartment. The
point sensor S2 monitors the corresponding feeder breaker
compartment and busbar compartment. Trip contact T1 is
responsible for tripping circuit breaker of the outgoing feed-
er. The detailed instruction is described in EAFR Standard
Arc Configurations booklet.
