I have a issue with a ML1000 solid red fault light. Every time I cleared the fault, try to put it back in run mode, it would fault out again.. I went though the fault screen and changed all the 1's to 0's then cleared fault. It worked I was able to put it back into run mode..Only problem is that the sensor that caused the fault is still not working, I've replaced with a new one an still not working. So, I went ahead an put the input on another input bit. nothing...the program will not read the input at all. So, then I replaced the PLC and downloaded the program over into it. Nothing, everything works except the sensor input NO signal to input,, I have 24v from plc to sensor. Need some help guys.. Been forcing to make the input work...last night 2nd shift tech was able to run machine 10 cycles then it faulted again...

I had the same issue with a ML1000 solid red fault light. Everytime I cleared the fault, try to put it back in run mode, it would fault out again.. I read and did what Swimmy67 said to do. It worked I was able to put it back into run mode..Only problem is that the sensor that caused the fault is still not working, I've replaced with a new one an still not working.

I did look at the attached file that TEJ sent out looks like this ML1000 1761-L32BWA is on the list... need some help!!!!!!!!!!!!
