alarms management

Besides managing all machine functions,
the electronic system of this espresso
machine controls their proper execution.
In case of anomalies, an alarm is recorded
and displayed.
WARNING: The incorrect use of the machine
can also generate an alarm. In this case it is
sufficient to correct improper use.
Some of the alarms are non-influential for
the proper functioning of the machine.
These alarms are only displayed and not
stored in the system memory. This type
of alarms is marked as "A". Other alarms,
indicating anomalies regarding safety
or correct functioning of machine parts,
are displayed and recorded with their
triggering date and time. They can block
the anomalously functioning part and
are marked as "ABP". Only some alarms
totally block the machine functioning and
are marked as "ABT".
