What to do if the PWR LED is turned off on my Mitsubishi Electric Controller?
If the PWR LED is off on your Mitsubishi Electric Controller, it may be due to an improper voltage supply. Ensure the power source provides the correct voltage. If the PWR LED turns on after correcting the power supply, it indicates that the service power supply might be shorted or overloaded. Try reconnecting the modules and wiring one by one to identify the cause.
Why is the BAT LED on my Mitsubishi Electric FX5U illuminated?
The BAT LED on your Mitsubishi Electric Controller might be on because the battery is not installed properly. Make sure the battery is correctly installed. Also, if the battery voltage is low, replace the battery with a new one.
