I was moving some stuff around in my shop and had to put a longer cord on the shaper. When I finished I flipped on the converter and I got a smoke show. Instantly! You could hear it.
So I shut off the converter switch quickly, but there was too much smoke to see where exactly it came from. As the only thing I had changed was the cord I took it all apart to check connections, all looked good with no sign of burning. I checked the cable for breaks and it was good. I checked the wires from the box to the main cutoff that shuts all down and they were good. Looked all over for any sign of burning, could not find any.
The main shutoff was on but the emergency stop button on the start stop panel was off. Found a few connections that were a touch loose, but not bad.
It blew the 50 Amp fuse on one leg of the switch downstream of the converter, and it blew one breaker in the control panel. I checked all I knew how to check and checked a lot I do not but could find no damage. So I turned it back on and both motors fired up just fine, even threw a piece through each spindle to see how it was under load, no problem.
I'm really confused. I am trying to find something that does not seem to exist, but where the heck did the smoke come from and what blew the fuse?
I have work to do and will be running it tomorrow, but this has me spooked a bit. Oh, in case you are confused, this is a double spindle unit.
I checked the converter and I have a 30V swing from high to low. I have been trying to get some one out here to work on it but has not happened yet. Thinking Phase Perfect....
Thoughts? Don't get to crazy on your explanation, I am not good at this stuff so when someone tries to impress me with their knowledge and forgets who they are talking to, well, you know..........
Thanks, Larry
