Alarms are managed by the software in the following way:
•
FILTER 80%:
it turns on after 600 hours of operation to indicate that an overall check of filters is
necessary (if not cleaned or replaced before) and of the unit as well, to verify if it operates
correctly.
•
FILTER EXHAUST:
it turns on when the filter pressure differential gauge detects a specific
difference value (set by the Manufacturer) between the inlet of dirty air and the outlet of clean
air on the filter.
In addition to the visual alarm on the control panel, the unit is also equipped with an acoustic signal
generated by a buzzer.
It is possible to deactivate the acoustic signal and keep only the lighting alarm.
On the pc board there are the following menus:
•
TEST MENU
•
USER MENU
•
ASSISTANCE MENU
•
FACTORY MENU
When the Filter Exhaust alarm turns on, it is necessary to replace the filters as indicated under point 7.3
and to reset alarms in order to restore normal operation.
