Significance
Color
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 o.k.
=> Correct the rotor/stator alignment.
If the LED still pulsates red, it is possible that there is a hard
ware 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.

Significance
Green
(permanently lit)
Measurement signal transmission and internal stator voltages
o.k.
Green, intermittently
orange.
Numerous synchro
nization errors:
permanently orange
Orange if
y
5 measured values in succession are transmitted
incorrectly, until the end of incorrect transmission. The mea
surement signals reflect the level of the fault for the duration
of the transmission error + for approx. another 3.3 ms.
Orange
(permanently lit)
Permanently disrupted transmission, the measurement sig
nals reflect the level of the fault. (f
out
= 0 Hz, U
out
= defect
level).
=> Correct the rotor/stator alignment.
Red
(permanently lit)
Internal stator defect, the measurement signals reflect the
level of the fault (f
out
= 0 Hz, U
out
= defect level).
