Any Alarm events that may have occurred (Event 0 to Event F) are
stored in the internal register. All detected events remain stored until the
register is manually reset (by pressing ENTER key or by means of the
digital communication interface). The Alarm Event Log register is
mapped to the SRAM (volatile memory). In case of power interruption
the Alarm Event Log register will be automatically reset.
