15.8. Alarm history
The alarm history menu shows up to 100 alarm events recorded according to the FIFO (first in first out) principle. The
101st (most recent) event overwrites the oldest event.
Resetting the alarm buffer is not possible: the recorded alarms cannot be deleted.
The year in which the alarm occurred is not stored, only the month and day are shown.
For each alarm, the log records the day and time of occurrence, clearance and manual acknowledgement (if class A),
which facilitates diagnosis and troubleshooting.
15.9. Alarm maintenance (filters)
By means of the maintenance alarm function (filters), it is possible to indicate via an alarm visible from the “Active
alarms” or “Alarm history” page that the set maintenance interval has expired and that preventive maintenance is
required on the filters or on other components, since this function can be used for more than just the filters.
One month corresponds to 30 days, and the countdown starts as soon as the unit is switched on.
When the power is off and the controller is not operating, the countdown is not implemented.
Example:
If a deadline of 12 months is set, the alarm will be activated after 12 months X 30 days/month = 360 days.
If the power supply to the unit has been cut off for a total of 3 days, the alarm will be activated after 363 days.
It is not possible to know the number of days remaining or to specify an anniversary date. This function must be
activated during commissioning by setting an interval other than 0.
