I have fixed this error several times simply by tightening the grounding clamp/plate where all the cables enter the control cabinet.

Try this first.

Second Shift.

But what time on second shift?

Wouldn't be after external or internal lighting kicks on would it?

A similar issue occurred many moons ago and after much troubleshooting and teeth gnashing it was tracked down to a ballast failing on an outside light. This was spiking the system and causing all sorts of goblin and gremlins.

So now whenever I hear time related issues like that it is the first thing I think of.

You are not the first nor will you be the last.

Does you're PLC output a "Auto OK" bit to you're controller?

That would be my first look.

If something is dropping out it can be hard to see it happen. Put a bit on that output then trigger an RTO counter with that bit and see if it increments.

Then go from there.

Just my 2.

I would make the intruder have to press a reset outside of slow zone to insure that they have left said safe zone.

Just to eliminate any confusion or monkey business.

I have eliminated that error on several robots by merely tightening the grounding clamp that compresses onto the incoming cables at the bottom of the controller.

If you can access PLC program you should be able to find the bit that is triggering the alarm and see what cause is.

I did the industrial automation for our factory in a "different country". They would tell us they were industrial grade batteries and that was denoted the same on the battery. However they would go to the local electrical mall and buy batteries that had been on the shelf since somewhere around the turn of the century. Same issue, 3-6 months and they were dead.

Just saying.

You may want to consider pulling your battery box out and inspecting the back for corrosion or damaged wiring. I have seen it before.

How stable is current company? How stable new company? To me that is most important question.

This is what works for me.

Depends on where you live. Fanuc has facilities around the US. I went to Rochester Mi. It was great.

The problem will probably come down to corrosion built up during the down time. A contact or connection, something.

Regardless of how many time they tell, ask, order, or threaten you if someone gets hurt on an unsafe machine that you made run, guess who's behind is in the soup, yours.

Be safe, your family will thank you.

Good luck

Do you have indices that tell you the robot is at home, (LED's, etc)? Do you watch the program on your tp when you press auto start, it should either start or give you an alarm why not. Is there a PLC in the mix? The stoppage could very well originate from the PLC, which if PLC is programmed well should kick out an alarm as well. Start from basic and work out.

Does your program require a certain position to auto start?

Fairly good article here.

Did you inspect the inside of the battery holder? I have seen then severely corroded and not passing the correct power. Pull out batteries and inspect inside of box.

Thank you for sharing the solution. It is always appreciated.

Your IT guys should be able to tell you in about 5 minutes flat. I could and I am the lowest IT tech here.
