When alarm occurs:
1) A-CLR input logic is OPEN, alarm is not reset.
2) At point A, A-CLR changes from OPEN to
CLOSED, the alarm is cleared.
When alarm occurs:
1) A-CLR input logic is CLOSED, alrm is not reset.
2) At point A, A-CLR changes from CLOSED to
OPEN, the alarm is NOT reset.
3) At point B, A-CLR changes from Open to
Closed, the alarm is cleared.
4 Open
In normal state, the input must remain in CLOSED(Low level) state. This is an edge trigger signal,that
