Attention:
When the wind vane rotates over the north point (0 / 360°) the
potentiometer slider connects beginning and end of the
potentiometer. Therefore, the supply voltage of the potentiometer
must show a current limitation of max. 1 mA. When using power
supply units temporary current peaks with the power control might
lead to damages. Therefore, an additional protective resistance Is
strongly recommended .
