6.2.1 Events (Alarms and Messages)
Each of the following listed events can be displayed on the LCD screen.
Alarms and Messages are differently specified because the alarms are indicating an abnormal
functioning of the ISM (which are additionally signalled with the LED alarm and acoustically with the
buzzer), while the messages indicate the various states of operation of the ISM (stored in the events list,
but not activating the LED alarm and the buzzer).
When in alarms mode, the LCD screen displays a time ordered sequence of screens corresponding to
the last 256 alarms and messages, each screen indicating:
The number of the event (255 = the most recent).
The date and time when the event occurred.
The standard code and the status word.
An explicit text description of the events.
