When a remote I/O module of function version C or later is used, the ERR. 
LED remains off even if one or two power supply modules fail. 
Confirm the failure of the power supply module on the LED of the module. If 
the power supply module is mounted on an extension base unit, the error 
can also be confirmed by the ERR contact of the power supply module. (For 
the specification of the LED of the power supply module, refer to QCPU 
User's Manual (Hardware Design, Maintenance and Inspection).)
