Troubleshooting
This chapter describes how to identify and rectify faults on the camera system.
8.1
Overview of potential errors and faults
8.1.1
Errors during mounting
1. Camera system poorly aligned to objects with 1D/2D codes (e.g., dazzle)
2. Read-cycle sensor incorrectly positioned (e.g., internal reading gate is opened too late
or closed too early)
3. Focus position switching: sensors for detecting the respective object height incorrectly
positioned
4. Incremental encoder (optional) incorrectly positioned
8.1.2
Error during electrical installation
•
Interfaces of the camera system incorrectly wired
8.1.3
Errors during configuration
•
Functions not adapted to local conditions, e.g., parameters for the data interface not
set correctly
•
Device limits not observed, e.g., reading distance, aperture angle
•
Trigger source for read-cycle not selected correctly
8.1.4
Faults during operation
•
Tracking operation: minimum distance of the objects in the conveying direction not met
•
Time-out period of the illumination unit exceeded
•
Device faults (hardware/software)
8.2
Detailed fault analysis
8.2.1
LEDs on the camera
A number of statuses can be read from the LEDs by the electrical connections of the
camera (see chapter
), including the following:
•
Result of the self-test
•
Operational status
•
Fulfillment of a configured condition (e.g., display of Good Read)
•
Maintenance or service activity required
The LED display can indicate possible errors or faults.
Further information on this can be found in the “System information” section.
