Diagnostics and trouble shooting
Typical errors and their possible causes are described in the following list as well as tipps for their elimination:
1. Is the device connected to a suitable power supply from the PC– means device and PC/PLC should be
connected to each other before switch ON. The external power supply should have 6VDC/1A
2. If you use the separate Power plug please check the connections
3. Make shure the interface cable is fixed correctly at the PC/PLC. Details for the interface are printed
usually in the manual of the PLC/PC.
4. If you checked all steps before and the device is still not ready, change the power supply to another one.
5. Please check the used interface at the device and your PC/PLC are compatible. Information about that
are printed in the PC´s /PLC´s manual.
6. Barcode: Please check the quality of the Barcode Labels, and the correct symbologies are released.
Damaged labels (scratched, dirty or crinkled) can cause hardly readable or not readable codes.
7. RFID: Please check the settings for RFID and check the transponder type with your supplier. If the
settings are correct the transponder can be defect as well- try another one if possible.
8. Now you checked most possibilities. For further support please contact the Leuze Service.
