3.1.2. Electronics
•The electronics cannot be tested without load (motor), the control
circuit has to be closed.
•The function of the electronics is released when the speed values
correspond to the test data.
Attention!
At supply voltage, the machine may only be operated with correctly loaded
electronics, otherwise the control circuit is interrupted and the speed
increases to prohibited levels.
