8.1 Rotor status, LED A (upper LED)
Color Significance
Green (pulsating) Internal rotor voltage values ok
Flashing orange
Rotor and stator mismatched (an increasing flashing
frequency indicates the degree of misalignment)
=> Correct the rotor/stator alignment
Pulsating orange
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 fault.
Red (pulsating)
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 fault.
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.
