I have a very old mechanical stamping press here that was only used for die tryout for the longest time, and now they want to use it for minor production jobs. In order to bring it up to code though, it must have anti-repeat and anti-tie down capabilities.
I have a 2 button palm station and both must be active to actuate the dual safety valves. But as of now, you can hold the buttons down and cycle in continuous as there is no angle feedback of any kind.
I was hoping someone might have a suggestion on a cheaper alternative to completely updating everything to achieve this though. If I have to have a cam switch or resolver/encoder setup, it will take some engineering as there is no location for either currently. Would limit switches be viable for location to force stops at top dead center for anti-repeat? Timers for anti-tie down?
I know what's required as far as operations and dual channel safety. I just don't know what's allowable in components used to achieve it.
