CPU Down Error - Power Supply / Hardware Failure
Mitsubishi Electric · MELSEC System Q/L Series
¿Qué significa 1009 ?
An error is detected due to an out-of-specification voltage waveform applied to the power supply module, or a failure in critical hardware components. This includes the power supply module, CPU module, main base unit, extension base unit, or extension cable. In redundant systems, failure of both redundant power supply modules or the redundant base unit can also trigger this error.
Causas comunes
- Voltage waveform outside the specification applied to the power supply module.
- Failure detected on the power supply module or CPU module.
- Failure detected on the main base unit, extension base unit, or extension cable.
- Redundant power supply module failure in both systems (when using redundant base unit).
- Redundant base unit failure (when using redundant base unit).
Pasos de reparación & Lista de verificación
Haga clic en los pasos para seguir su progreso.
- 1
Correct the voltage waveform applied to the power supply module.
- 2
Reset the CPU module and attempt to RUN it again.
- 3
If the same error is detected again, diagnose for and replace the defective component among the power supply module, CPU module, main base unit, extension base unit, or extension cable.
