	The AC power supply is faulty. If this error message appears when you turn the controller off, it means no problem.

Do not connect or disconnect the cable with the controller power on. Be sure to turn off the controller power switch. 3. If the error persists after rebooting the controller, you need to investigate or repair the controller.
