Hello Guys,
I'm new on the forum. There was power outage on my production line some days back but after it was restored, the line did not start up.
While troubleshooting,we noticed an EXTERNAL FAULT displayed on the PLC. We eventually discovered the UPS for the PLC was not on before the power outage so we put it on and reset the PLC then the line could start up.
My question is; what are the likely causes of having an External Fault on a PLC?
And how do I fix it when it comes up.
Thank you
