AUTOMATIC TO MANUAL RESRT ALARMS DIAGNOSTICS
N° OCCURRENCES PER HOUR
Every hour is divided into 60 intervals, 1 minute each.

On device start every observation interval is marked as "not active".
At the beginning of every observation interval it is marked "not active" and so on until it is concluded. It is
marked "active" if at least one alarm has occurred.
At the end of every observation interval, move to the next remembering that it is continuous observation and
when the first 60 intervals have finished the 61
st
overwrites the first, the 62
nd
overwrites the 2
nd
and so on.
The last hour of work is always monitored in this way and all "active" intervals can be counted. When the n°
of active intervals exceeds the threshold set, the alarm becomes manual. By setting the threshold at 0 the
alarm will be manual already at its first intervention, while by setting the threshold at 60 the alarm will always
be automatic reset as 61 observation intervals do not exist.
