Overview of possible errors and faults
Table 13: Errors and faults
Situation
Error/fault
Mounting
■
Device poorly aligned to the object with the bar code (e.g.
dazzle).
■
Read-cycle sensor incorrectly positioned (e.g., internal read‐
ing gate is opened too early or closed too late).
■
Incremental encoder incorrectly positioned.
Electrical installation
■
Data 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. reading distance, aperture
angle.
■
Read cycle trigger source not selected correctly.
Operation
■
Read cycle control incorrect and/or not suitable for the
object.
■
Device faults (hardware/software).

Detailed fault analysis
10.2.1
LEDs on the device
The conditions that can be read from the device LEDs on the sensor housing (
) include:
■
Operational readiness (Ready)
■
Reading result status (Good Read or No Read)
■
Hardware fault
■
Firmware download status
■
Connection status of the device
The LED display can indicate possible errors or faults. Further information on this can
be found in the “System Information” section.
10.2.2
System information
The device outputs faults in different ways. Fault output is staggered and thus 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
(
10.3
Status log
NOTE
The status log is retained even after switching the device off and on again.
The device distinguishes between four types of fault:
