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. AUORA 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.
