¾ Last 100 fault conditions with error code and time stamp
¾ Last 100 variations to the grid connection parameters with parameter code,
new value.
All data are available for transmission via the RS-485 link or PLM. In addition, the
first two data of the list are displayed on the LCD. The AURORA Communicator
software shall be used in order to download the internally stored data.
5.3 LED Indicators
On the front panel of the AURORA inverter there are three LEDs, which give
status indications:
1. A green LED labeled “Power” to signal AURORA normal operation.
When the unit is started-up, during grid parameter’s check-up, this led is
blinking. If a “valid” grid voltage is detected the LED lit on permanently
in case there is enough solar radiation. Conversely the green LED keeps
blinking until solar radiation exceeds a minimum threshold value to
ensure inverter activation and power export to the grid. During this phase
the LCD shows the message “Waiting Sun…”
2. A yellow LED labeled “FAULT” to signal that AURORA have detected a
fault condition. The Fault condition (or error code) is displayed on the
front LCD
3. A red LED labeled “GFI” (ground fault) to signal that AURORA have
detected a ground failure in the DC section of the photovoltaic system.
When a ground fault is detected AURORA immediately disconnect from
the grid and the LCD displays the corresponding error message.
AURORA remains in this status until the operator push the “ESC” button
(# 4) in order to restart the grid connection sequence. However if the
inverter is not able to resume the grid connection, please call the technical
assistance to identify and remove the failure.
