5.4 Messages and error codes
The system status will be identified by message or error signals, shown on the LCD
display.
The tables below summarized the two types of signals which may be displayed.
The MESSAGES indicate the current status of AURORA, they are not caused by
faults and do not involve any action; the messages will disappear once normal
conditions are re-established (See the W lines in the following table).
ALARMS indicate a possible fault in the equipment or connected parts. The signal
will disappear once causes are removed, except in the case of ground isolation
problems, for which qualified personnel will have to be called in order to have the
system restored to normal operation. The appearance of an error signal generally
involves some form of action by the installer of by the Power-One Service. The
AURORA photovoltaic inverters will show on display much helpful information as
possible to those performing the necessary maintenance on the equipment or system.
See the E line in the following tables.
