Troubleshooting
Self-diagnostic Function
The Controller has a self-diagnostic function to check a variety of items in order to reduce the downtime of the
system that may result due to operational failures.
Details of Errors
Errors detected by the Controller can be classified into fatal errors and nonfatal errors.
• Fatal Errors
If the hardware of the Controller fails, the operation of the CPU Unit will be interrupted and the ERR
indicator will turn ON or flash.
• Nonfatal Errors
If an error occurs in communications between the Controller and host device or between the Antenna
and Tag, the ERR indicator will turn ON.
