3.3 Operating modes
The operational status is displayed using three light-emitting diodes (LEDs) in the
cover of the Windy Boy 5000 / 6000. To allow the device to signal its operational
status via the integrated LEDs, the Windy Boy 5000 / 6000 must be connected to the
DC side of the system. There must be enough wind energy present, so that the Windy
Boy 5000 / 6000 has adequate DC voltage.
A complete description of the possible displays can be found in chapter 3.3.4
"Description of the operational status” (page 19). These can be split into three
categories:
3.3.1 Normal operation
As long as the green control LED is on, or blinking, the Windy Boy 5000 / 6000 is
operating normally. The simultaneous illumination of all three LEDs is also an
indication of normal operation ("Initialization"). All other displays are a sign of
abnormal operation.
Especially in the first year of operation, the operator of the system should
check this display under different wind speeds.
