Overview of possible errors and faults
NOTICE
Danger due to damage to the device
For reasons of safety, if a device shows visible signs of damage do not put it into
operation. Immediately take a device that is in operation out of operation.
Damage includes, depending on the type of device, for example the following:
•
Viewing window pane: Cracked or broken
•
Housing: Cracked or broken
•
Violation of the cable outlet on the housing or the cable itself
•
Overtightening of the male connector unit, tearing or breakage of the housing
•
Moisture penetration in the device
Possible faults and corrective actions are described in the table below for troubleshoot‐
ing.
Table 12: Errors and faults
Situation
Error or fault
Mounting
■
Device poorly aligned to objects with bar codes(e.g., dazzle)
■
Read cycle sensor incorrectly positioned, for example the inter‐
nal reading interval is opened too early or closed too late.
Electrical installation
■
Data interfaces of the device wired incorrectly
■
Voltage supply not sufficiently dimensioned or cables with too
small a cross-section used
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
■
Control of the reading pulse not correct or not suitable for the
object
■
Device faults (hardware/ software)

Detailed fault analysis
10.2.1
LEDs on the device
The statuses that can be read from the upper sensor LED on the housing of the device
(
see "Optical displays", page 53
) include:
■
Operational readiness (Ready)
■
Reading result status (Good Read or No Read)
■
Hardware fault
■
Firmware download status
The status of communications with the PROFINET can be read from the four lower
network LEDs:
■
Connection status of the device with PROFINET
■
Data traffic with the controller
The LED display can indicate any errors or faults with this. Further information for this
can be found in the system information.
