Troubleshooting

8.1

Warnings and fault messages

If a malfunction arises in the LD-MRS, it emits warning and error messages via the ethernet
interface.
The operator can extract the warnings and fault messages from the Ethernet data stream.
If the SICK LaserView Customer Edition is used to visualize the scan data, the errors are dis-
played there.

See the operating instructions, "SICK LaserView Customer Edition visualization tool (Part
No. 8013786), section "Trace log".
The warnings and fault messages contain Bit fields, each Bit represents one warning or one
fault. Available are a maximum of twice 16 Bit each for warnings and faults.

8.2

Overview of possible errors and faults

8.2.1

Mounting error

•

LD-MRS not mounted conveniently (e. g. limited field of vision)

•

LD-MRS adjusted incorrectly (angle of rotation)

8.2.2

Error in the electrical installation

•

Interfaces of the LD-MRS switched incorrectly

8.2.3

Parametrization error

•

Device limits (scanning range) not considered

•

The parameters are not adapted to local conditions.

8.2.4

Fault during operation

•

Device error (hardware/software)

8.3

Monitor error and fault indications

The LD-MRS monitors itself during operation:

•

After switching on the supply voltage, the LD-MRS first runs a self-test checking import-
ant hardware components before initialization (loading the parameter set and initializ-
ing the device functions).

•

In case of an error, the LD-MRS sends warning and error messages via the Internet in-
terface; see

Chapter 8.1 Warnings and fault messages, Page 91
