Troubleshooting
9.1
General faults, warnings, and errors
Possible faults and corrective actions are described in the table below for troubleshoot‐
ing. For faults that cannot be resolved using the information below, please contact
SICK Service. To find your agency, see the final page of this document.
Table 17: Other possible error sources
Situation
Error/fault
Mounting
■
Device poorly aligned to objects with codes (e.g. glare)
■
Trigger sensor for reading cycle incorrectly positioned (e.g.
internal reading interval is opened too late or closed too early)
■
Incremental encoder (optional) incorrectly positioned
Electrical installation
■
Interfaces of the device incorrectly wired
Configuration
■
Functions not adapted to local conditions, e.g., parameters for
the data interface not set correctly
■
Device limits not observed, e.g., working range, aperture angle
■
Trigger source for read cycle not selected correctly
Operation
■
Start/stop operation: external read cycle missing, more than
one object is in the reading field
■
Device faults (hardware, software)

Detailed fault analysis
9.2.1
LEDs on the device
The conditions that can be read from the LED on the device housing (
) include:
■
Operational readiness (Ready)
■
Status of the analysis result (pass or fail)
■
Hardware fault
■
Firmware download status
■
Connection status of the device
The LED display can indicate any errors or faults with this. Further information for this
can be found in the system information.
9.2.2
System information
The device outputs faults in different ways. Fault output is staggered and therefore
allows for an increasingly detailed level of analysis:
•
Communication errors can occur when transmitting data to the device. The device
then returns a fault code.
•
For faults that occur during reading, the device writes fault codes in the status log
(
9.3
Status log
NOTE
The status log is retained even after switching the device off and on again.
The device distinguishes between four types of faults:
