1)Sleep Mode
AURORA is in the disconnection phase; this happens whenever the input power is too low to export power to the feed grid and power the inverter control system as well.
2)AURORA Initialization and Grid Check
The unit is in the initialization phase: energy supply for the inverter control system is high enough. AURORA is also checking that starting conditions – such as input voltage, starting time, etc. - necessary for the initialization process, are satisfied. Grid check is then started.
3)AURORA Under Production
Once all electronic and safety
As stated above, during this phase AURORA carries out an automatic search and analysis of the wind turbine power curve max power point tracking (MPPT).
4)Ground Insulation
The inverter signals a ground fault.
This can be due to an insulation defect in the wind input connection.
Insulation Defect
An insulation fault condition has been detected in the input wiring from the Wind Interface box or a corresponding connection is conductive with the grounded potential.
WARNING: Trying to remove the fault by yourself is extremely dangerous. The instructions below have to be followed very carefully. In case you are not experienced or skilled enough to work safely on the unit, contact a specialized technician.
What to do after an insulation defect has been found Whenever the red LED comes on, press the special multifunction
