Mains supply impedance is too high
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 3 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 has detected a fault relating to an unacceptable
impedance in the mains supply. If the Windy Boy 5000 / 6000 frequently displays
this fault during mains monitoring, the cause can be a mains impedance that is too
high. An electrician can usually assist with this problem by increasing the cross section
of the mains connection cable. Other measures can be taken to correct this problem,
but they require the agreement and cooperation of the electricity supplier.
Input voltage too high
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 4 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.
Immediately disconnect the DC input of the Windy Boy 5000 /
6000. The presence of excessive input voltage can lead to
irreparable damage! Make sure that the input voltage never
exceeds 600 V.
