Functionality testing
You can check the functionality of the rotor and the stator from the LEDs on the
stator.
LED A, rotor status
LED B, stator status

Important
Once the supply voltage is applied, the torque transducer needs up to a further
4 seconds to be ready for operation.

Significance
Green (pulsating)
Internal rotor voltage values o.k.
Flashing orange
Rotor and stator mismatched (an increasing flashing fre
quency indicates the degree of misalignment)
=> Correct the rotor/stator alignment.
