ADMA 3.5 Quick Start Guide.docx
Seite / Page 31 / 32
Possible causes:
•
Excessive movements of the vehicle during prealignment. Please avoid
all vehicle movements during prealignment.
•
Pre-alignment too short. Adjust the prealignment parameter in the
ADMA Webinterface (
Behaviour / Pre-alignment duration
).
Fault:
The coordinate system is rotated, the longitudinal speed VX becomes
the lateral speed VY.
Possible causes:
•
An incorrect start angle has been entered for operation without
Autostart. The Kalman filter does not oscillate correctly. If the start
angle is not known, please enter zero. The Autoinit function determines
the angle automatically.
•
No GNSS reception when starting the measurement. If there is no GNSS
reception when starting the measurement, a course angle must be
specified.
Fault:
No data on the CAN bus
Possible causes:
•
The selected port ADMA Webinterface (
Data Link / Interface selection
) is
incorrect.
•
The CAN interface configuration is incorrect (e.g. baud rate)
•
The option that stops the measurement with a faulty ACK is active.
•
The measurement was started before the CAN cable had been
connected to the ADMA.
•
The CAN bus is defective or connected incorrectly. Please check the
terminating resistor.
Fault:
GNSS failure results in the output of an implausible speed value
Possible causes:
•
Additional speed sensor is mounted at an angle.
•
Additional speed sensor is not available but has been activated in the
ADMA Webinterface (Aux Systems
/ External velocity in x/y
).
Fault:
Correction data cannot be received
Possible causes:
•
Incorrect operating mode in the ADMA Webinterface (Aux Systems
/
DGNSS preset
). Selection of base station via radio modem, correction
data service / Base Station with GPRS modem or satellite-based via
SBAS.
•
The internal GNSS receiver is not approved for DGNSS/RTK operation.
Common radio modem faults:
•
Incorrect configuration of the radio modem (frequency or spacing)
