Troubleshooting
This chapter describes how errors at the ICR890 High-end CCD Camera System can be
recognised and eliminated.
8.1
Overview of errors and malfunctions which could occur
8.1.1
Installation error
•
The ICR890 System has been unsuitably aligned to objects with 1-D/2-D codes (e.g.
visual glare)
•
Reading pulse sensor has been incorrectly positioned (e.g. internal reading gate opens
too late or shuts too early)
•
Focus switching: Sensors for detecting object heights positioned incorrectly
•
Incremental encoder (optional) positioned incorrectly
8.1.2
Electrical installation error
•
Interfaces of the ICR890 System wired incorrectly
8.1.3
Configuration error
•
Functions have not been adjusted to the local conditions, e. g. parameters for the main
data interface set incorrectly
•
Device-related limits have not been considered, e. g. reading distance, aperture angle
•
Selected trigger source for reading pulse incorrect
8.1.4
Malfunctions during operation
•
Start/Stop operation: External reading pulse is missing, more than one object is in the
reading area
•
Tracking operation: Minimum gap of the objects in the direction of transport not
achieved
•
Timeout of the ICI890 Illumination exceeded
•
Device error (hardware/software)
