ERROR MESSAGES AND CODES
The state of the system is indicated by a
warning sign (Warning) or an error sign
(Error) visualised on the LCD display.
The Table 20-1 which follows briefly
describes the two types of signals that may
appear.
20.1.
Warning
These indicate the state of AURORA,
therefore they are not caused by a fault and
do not imply the need for any action (lack of
grid, sun, etc.). These will cease to be
displayed as soon as normal conditions will
be restored. Warnings are indicated in the
table below by a “W”.
20.2.
Error
Indicate a possible fault of the apparatus or
of the elements connected to it. Also in this
case, the signal will disappear as soon as the
causes are identified. The occurrence of an
error
signal
generally
implies
an
intervention that is maintained by Aurora as
much as possible, or it will provide
appropriate indications in order to assist the
person working on the device or plant, to
perform the necessary maintenance. Errors
are indicated in the table below by an “E”.
After the connection, if the inverter receives
incorrect information during the test cycle,
the system will interrupt such cycle and will
signal the warning or error code.
The system will continue to repeat the
visualisation of the error message until the
error has been removed.
Once the error has been removed, the
inverter resets all functions in progress and
automatically restarts the connection.
