20T Press 1

[Ray306]

I have a 20T press in my shop that I've been working on for a week now. The press will not retract up. I replaced the upper limit switch that was going out, but it still will not go up. I can make it go up manually by hitting the switches, besides that nothing else will work. Help?

Remember that none of us on this forum have ever seen this press you're having problems with and thus have no idea how it's set up, how it's supposed to work, what switches you're "hitting", etc. Help us help you by giving us enough information to actually understand the problem. Nobody here likes playing 20 questions before we can actually start helping you.

If it works manually, then you may have the Normally Open contact and Normally Closed contact switched.
Typical travel limit circuits are wired N/C, then open when moved to cut power to the power source.
