46. MANUAL ALARM PROCEDURE
CONCEPT OF NUMBER OF EVENTS PER HOUR
For some alarms is possible to set a number of alarms per hour:
 if the alarm occours a number of time lower than the value set, the alarm is automatic reset
 if the alarm occours a number of time equal the value set, the alarm is manual reset
Each hour is divided in 16
th
intervals (each interval is 3600 / 16 = 225 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 .
