The system status is identified through message or error signals displayed on the LCD
display.
The tables which follow briefly describe the two types of signals which may be
displayed.
MESSAGES identify the current AURORA inverter status; they do not relate to faults
and nothing has to be done; the messages disappear as soon as the system is back to
normal operating conditions. See the W lines in the following table.
ALARMS identify a possible equipment fault or a fault of the connected parts. Alarm
signals will disappear as soon as the causes are removed, except for ground insulation
faults in the photovoltaic panels, which have to be corrected by qualified personnel in
order to restore normal operation. This appearance of an alarm signal will be managed
as much as possible by AURORA or, in case this is not possible, AURORA will
supply all the necessary help information to the person who will have to perform the
maintenance operations to fix the fault on the equipment or system. See the E lines in
the following table.
