This screen shows the history of active UPS alarms, in the order in
which they occurred.
Increasing number, alarm code, date and time identify the sequence of
the events. The list of the events is continually updated, applying the
technique known as FIFO (First In First Out); thus the oldest message is
eliminated when the most recent message is added to the list.
The asterisk represents the time in which the event starts. A line with the
same alarm code indicates the end of the event.
