Upon switchover to emergency power the PLC (Micrologix 1400) enters fault mode, major error code 0020h. The PLC is connected to a UPS and never lost power.
I switched the plc to mode program and then to run mode in order to reset the fault and it is operational again.
Any thoughts as to what may have casued this failure and how to resolve it? The only input that the PLC should have recieved due to the power switchover is loadsheds for the three pumps. (pumping station)
Thanks!
