Device faults
The yellow fault LED illuminates for 5 seconds when the fault occurs, and then begins
displaying the blink code of: 3 seconds off and then 5 times briefly on. This code is
displayed three times in succession. If the fault is still present, the fault display starts
again from the beginning.
When the Windy Boy 5000 / 6000 receives an excessive DC input voltage, it
automatically disconnects from the mains supply and no longer feeds power
into the grid. When the Windy Boy 5000 / 6000 is in operation, you must
always first disconnect the AC voltage (mains supply) and only then should you
disconnect the DC voltage from the Windy Boy 5000 / 6000!
If the device fault leads to a major reduction in normal operation,
the Windy Boy and the entire system installation should be
checked by an electrician.
