Mains supply fault
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 2 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.
The Windy Boy 5000 / 6000 indicates a mains supply fault with this message, which
can have the following causes:
• Low mains supply voltage (VAC < "Vac-Min")
• High mains supply voltage (VAC > "Vac-Max")
• Low mains supply frequency (fAC < "Fac-Min")
• High mains supply frequency (fAC > "Fac-Max")
• A change in mains supply frequency ("dFac")
Check if a general mains supply dropout has occurred (check the operation of other
mains supply devices), and check if the fuse of the feed-in connection of the Windy
Boy 5000 / 6000 is intact.
If one of these faults can be found, then the mains supply
connection of the Windy Boy 5000 / 6000 must be checked by
qualified electrical personnel.
