52 A4429-1.0 HBM: public T40FH
9.1 Rotor status, LED A (upper LED)
Color 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.
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.
9.2 Stator status, LED B (lower LED)
Color Significance
Green
(permanently lit)
Measurement signal transmission and internal stator voltages
o.k.
Green, intermittently
orange.
Numerous synchro
nization errors:
permanently orange
Orange if y5 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.
