What to do if the PW LED does not turn on in my Mitsubishi Electric Controller?

If the PW LED on your Mitsubishi Electric Controller doesn't turn on, it could be due to a hardware failure, in which case you should consult your local Mitsubishi representative. Alternatively, ensure that the module power supply (24VDC) is correctly wired and turned on. Also, verify that the voltage value is within the specified performance range.
