LED indicators

At the side of the display, there are three LEDs. The first from the left (POWER)
indicates the proper functioning of the inverter; the central LED (FAULT)
indicates the presence of an anomaly; and the right-hand LED (GFI) indicates a
ground fault.
1. The green LED "Power" indicates that AURORA is operating correctly.
When the unit is undergoing commissioning, and the grid is being checked, this
LED will be flashing. If a correct grid voltage is detected, the LED will stop
flashing, and will emit a steady light, as long as solar radiation is sufficient to
start up the unit. If not, the LED will continue to flash until solar radiation
becomes strong enough to start up the inverter. During this phase, the LCD
display will show the message "Awaiting sun..."
2. The yellow LED "FAULT" indicates that AURORA has detected a fault. The
type of problem will be shown on the display.
3. The red LED "GFI" (ground fault) indicates that AURORA is detecting a
ground fault in the DC side of the photovoltaic field. When a fault is detected,
AURORA will immediately disconnect itself from the grid, and the relative
error message will appear on the LCD display. AURORA will remain in this
state until the operator presses the ESC key in order to restart the grid
connection process. If AURORA does not re-connect itself to the grid,
technical assistance must be called in order to identify and remove the cause of
the system fault.
