Functional testing

You can check the functionality of the rotor and the stator from the LEDs on
the stator.

7.1 Rotor status, LED A (upper LED)

Color
Green (pulsating)
Flashing orange
Pulsating orange
Red (pulsating)
Pulsating means that the LED goes dark for about 20 ms every second (sign
of life), making it possible to detect that the transducer is functioning.
HBM
LED A, rotor status
LED B, stator status
Meaning
Internal rotor voltage values ok
Rotor and stator mismatched (an increasing flashing
frequency indicates the degree of misalignment)
=> Correct the rotor/stator alignment
Rotor status cannot be defined
=> Correct the rotor/stator alignment
If the LED still pulsates orange, it is possible that there is a
hardware defect. The measurement signals reflect the level of
the defect status.
Rotor voltage values not ok.
=> Correct the rotor/stator alignment
If the LED still pulsates red, it is possible that there is a
hardware defect. The measurement signals reflect the level of
the defect status.
