5-2 Troubleshooting
This section provides basic error identification, troubleshooting flowcharts, and error corrections. Use
them when an error occurs in the NA Unit.
When an error occurs in the NA Unit, use the following flowchart to determine whether the error is a
fatal error or a non-fatal error.
 Power Supply Error
Check the following items:
• Is the NA Unit correctly connected to the external DC power supply?
• Is the voltage supplied from the external DC power supply within the allowable range?
 Hardware Error
Turn OFF the power supply, disconnect all devices connected to the NA Unit, and then turn the
power supply back ON. If the NA Unit operates normally, the cause of the error is in a disconnected
device.
 System Program Error
Execute system recovery.
 Runtime Error
Download the project again. If you cannot download the program, execute system recovery.
