Overview of Potential Errors and Faults
WARNING
Risk of injury due to damage to the device
For reasons of safety, a device which is visibly damaged must not be operated or must
be immediately taken out of operation. Damage may include, depending on the device
type:
•
Housing: cracking, splitting or fracture
•
Electrical connections: cracks or detachment from the housing
•
Device with cable connection: damage to the cable outlet or cable itself
Table 17: Errors and faults
Situation
Error/ fault
Mounting
■
Camera system poorly aligned to objects with 1D / 2D codes
(e.g., dazzle)
■
Read-cycle sensor incorrectly positioned (e.g., internal reading
gate is opened too late or closed too early)
■
Focus position switching: sensors for detecting the respective
object height incorrectly positioned
■
Incremental encoder (optional) incorrectly positioned
Electrical installation
■
Interfaces of the camera system 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., reading distance, aperture
angle
■
Trigger source for read-cycle not selected correctly
Operation
■
Tracking operation: minimum distance of the objects in the
conveying direction not met
■
Device faults (hardware/ software)

Detailed fault analysis
9.2.1
LEDs on the device
The following states are indicated by the status LEDs of the device:
•
Result of the self-test
•
Operational readiness (
Ready
)
•
Read result status (“Good Read” or “No Read”)
•
Maintenance or service activity required
The status LEDs can indicate possible errors or faults. Further information on this can
be found in the “System Information” section.
The LED signals are described in Chapter
"Display and operating elements", page 16
of
this product documentation.
9.2.2
System information
The device outputs any occurring faults in different ways. Fault output is staggered,
allowing for an increasingly detailed level of analysis:
