5.4 Messages and Error Codes
The system status is identified through message or error signals appearing on the LCD.
The table that follows summarizes the two types of signals that can be displayed.
MESSAGES identify the current Aurora inverter status; so they do not relate to faults
and nothing has to be done; messages disappears as soon as the system is back to
normal operating conditions. See the W strings 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.
Usually, when an error signal appears, an action is needed. This action 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 strings
in the following table.
