If short circuit at “Zone 1”,
“ Active B” LED of
Isolate
Interface A
and “ Active A”
LED of
Isolate Interface B
will emitting ,“Detection
Zone 1” will be isolated.
If “Zone 3 ” had short circuit
fault,the
Isolate interface C
will start to isolate, “Active
B”of Isolate Interface C will
emitting. And A side of
Isolate Interface D
also start
to isolate.
Testing
