The power supply lamp of a running programmable controller suddenly turned off or flashes

The power supply lamp of a running programmable controller suddenly turned off or flashes
Category : 

Answer

Check whether the lamp is back to normal after disconnecting the wiring of the "24V" (service power supply) terminal.
If the lamp is back to normal, the service power capacity may be exceeded due to a load short-circuit and too much load current, possibly opearting the protection function.
If the lamp is not back to normal, please consult your local Mitsubishi representative.
