Derating
The temperature monitoring of the Windy
Boy has reduced the output power to
prevent the device from overheating. If
this occurs often, this is an indication of
inadequate heat dissipation or excessive
input current.
•
Temperature derating
To avoid unnecessary reductions in
yield, in this case it should be
checked if the Windy Boy can be
mounted in a more favorable
position with better ventilation.
•
Current derating
The input current on the DC side exceeds the maximum possible input current. The
Windy Boy switches to the "Current Derating" mode in order to protect itself
against overload. Check the system layout.
Defective Varistor or Isolation Error
The red LED on the Windy Boy is
constantly on. A grounding error has
occurred, or one of the thermally
monitored varistors on the DC input side is
defective as a result of overvoltage.
Consult a trained electrician to correct the fault using the installation
manual.
The green LED
