Machine just stops

Postby Georgi Baltov » Tue, Jul 13 2010, 1:08PM

Hi Guys,

We've had a strange machine behavior where it will just go into e-stop in the middle of operation. I can't really give you anything more than that. I took a print screen from the PLC history. See if you can make sense of it. I can't. Let me know if I can help you out collect any additional information that you may need.

Thanks

Hello Georgi,
If the machine is randomly stopping like that it will be difficult to "pin point" the cause easily. The next time it goes into e-stop, go to the plc screen and read the current error that shows up. That will get us pointed in the right direction. It may be as simple as dirty contacts on the e-stop switch or possibly the tooling lockout switch. The next time the problem arises, feel free to contact us here in the service department and we will be glad to assist you. 1-800-221-3865 My extension is 250.

Thanks,
Carl

Hi Carl,

here's a print screen from the current PLC screen.

Hello Georgi,
I researched the error. I believe it has to do with light curtains, or stop mats that were added to the machine. It is possibly a loose connection or a bad sensor causing the estop.
