8.2 Check by Using the LED
If there is trouble in using the XGB built-in positioning function, you can roughly presume the cause of the
trouble by checking the LED of XGB PLC. This chapter describes the LED related to the trouble of the
positioning function. With respect to the trouble that occurs during use of other functions of the basic unit, refer
to ‘Hardware section of the XGB Manual.’
8.2.1 LED Check
If there is trouble during use of the positioning function, check the status of PWR LED, RUN LED and
ERR LED of XGB PLC, and check the LED of the input and output contact point related to positioning.
(1) PWR LED Check
Check the PWR LED status and take the following actions.

• Rated voltage is normally supplied to
XGB.
• The power supply is normal, so check whether
there is another cause.
Flashing
• One of the following might be the
cause.
- Rated voltage/current set for the
XGB is not being supplied.
- Problem with the PLC hardware
- Problem with external lines
• Check the voltage and current of the power
supply.
• Remove the input and output lines, re-supply
power and check again.
- If there still is the same problem, contact the
