Rotor Status, Led A (Upper Led); Stator Status, Led B (Lower Led) - HBM T40B Mounting Instructions

Functionality testing
8.1

Rotor status, LED A (upper LED)

Color
Green (pulsating)
Flashing orange
Pulsating orange
Red (pulsating)
Orange (continuous)
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.
8.2

Stator status, LED B (lower LED)

Color
Green
(continuous)
Green, intermittently
orange.
Numerous synchro­
nization defects:
permanently orange
42
Significance
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 fault.
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.
Communication problem with rotor/stator. Outputs go to error
state
Significance
Measurement signal transmission and internal stator
voltages ok
Orange until end of defective transmission if y5 incorrect
measured values are transmitted in succession. The
measurement signals reflect the level of the fault for the
duration of the transmission defect + for approx. another
3.3 ms.
