Hello everyone, I've been having a problem for the last week and a half with a 503 processor installed on a 10 slot chassis with 7 slot expansion rack. The 10 slot rack contains the processor and controls 1 side of the production line while the 7 slot expansion rack controls the second half. After running for a few hours the 10 slot rack shuts down and would restart automatically while the second half continued to run with no issues. I added additional instructions to prevent the restarting portion, i replaced emergency stop contacts and safety relays, I changed the power supply (1746-P4)(Each rack has its own power supply) and i also changed the 10 slot chassis. Over the weekend, the operator informed me that the same line shut down but did not re-start which is great at least, but i am confused as to why it shuts down. I suspect it is a heat issue since the panel doesn't have any circulation fans and the job site is located in Palmdale Ca which is usually really hot in the summertime. Any Ideas?
