1. Function of the controller
We have only two controllers for all rotor sizes:
KR4 = 400 Watt – for wheel diameter ≤ 3760 mm
KR7 = 750 Watt – for wheel diameter >3760 mm
Special features:
the controllers are usable worldwide
all known regulations are taken into account by us
for construction of the controller
it is therefore the most modern generation of con-
trollers by far
the controllers are operated using only three but-
tons. The results and messages are displayed in a
lighted, two-part display
In hardwired condition, the controller is immediately
ready to operate after turning on the mains voltage
Faults are shown in the display
