10. Troubleshooting

If any malfunctions occur, refer to the following items after checking the power of the
controller.
Warning
Turn the power supply to the instrument off before wiring or checking.
Working on or touching the terminal with the power switched on may result in
severe injury or death due to Electric Shock.
