COMMON OPERATING FAULTS
Fault:
Kalman filter status does not reach the 100%
Possible causes:
•
- HW errors
•
- no GNSS or bad GNSS condition during initialization
•
- wrong compensation of the ADMA mounting angles (Roll/Pitch/Yaw)
•
- Auto-Init threshold not exceeded
•
- insufficient dynamics or initialization too short
Fault:
All the measurement channels display implausible values.
Possible causes:
The Kalman filter is unable to oscillate correctly due to a missing or
defective comparison of the offsets. Possible causes are:
•
The ADMA has been mounted opposite to the default installation
position and no comparison of the angle misalignment values has been
done in the ADMA Webinterface (
Parameter
/ Mounting offset angle
).
•
Lever arms have been entered in the ADMA Webinterface with incorrect
signs (
Parameter
/ Mounting offset GNSS antenna
).
Fault:
There is a permanent offset in the angle values (Nick/Roll).
Possible causes:
No angle comparison has been executed in the reference position. The
angle comparison can be executed automatically via the menu item
(
Parameter
/
Auto
Roll-Pitch alignment)
in the ADMA Webinterface.
Fault:
The course angle drifts and the coordinate system are rotated, the
longitudinal speed VX becomes the lateral speed VY.
Possible causes:
The standstill detection has been configured incorrectly. The standstill
bit displays "0" during standstill with the engine running. Please modify
the values in the ADMA Webinterface, (
Parameters / Standstill detection
).
Fault:
The measurement is cancelled, or temporary failure of the
measurement data, error bits are displayed.
Possible causes:
•
Low voltage problems during ADMA operation result in reinitialization
(the Kalman filter is no longer oscillating).
•
Low voltage problems during ADMA start-up result in erroneous
initialization of the sensors.
Please check the power supply and execute a restart.
Fault:
It is no longer possible adhering to specified accuracies.
