40 AUTOMATIC TO MANUAL ALARM PROCEDURE
NUMBER OF EVENTS PER HOUR
Each hour counting is divided in 16 intervals, each made of 3600 / 16 = 225 seconds (3 minuts and 45 seconds).
1°Int 2°Int 3°Int 4°Int 5°Int 6°Int 7°Int 8°Int 9°Int 10°Int 11°Int 12°Int 13°Int 14°Int 15°Int 16°Int
After the unit start-up, each interval is marked as “not active”. During the interval counting, for 255seconds, if at least an alarm event
appears, the interval itself is marked “Active”.
Starting from the first interval the instrument calculates the 16 intervals and, at the end, it restats overwriting from the first.
In this way the last hour is always monitored and counted the active intervals. when the number of active intervals reaches the threshold
set with the corresponding parameter the alarm becomes manual.
By setting the threshold (parameter)=0 the alarm is manual from its first activation while if the threshold=16 the alarm is always
automatic (In this case, to change in manual, the threshold should be 17).
