Anatol Trident 6/8 year 2000 optical safety sensor missing

I can snap pic of my trident tomorrow and post it here. Mine are pointed in toward one reflector so they don't trip erratically.

musterdbom, thanks a pic of the way your optical sensors wiring route would be awesome! If it yours is similar to our press thanks!

See pic below. The two cables coming in are from the sensors.

Musterdbom,
Thank you for taking the time to post a pic of your presses wiring.
Attached is a better pic of our presses wiring. Looks to me like you may have solved our problem. Looks like the sensor wires go were the arrow is. Is your press up and running, don't see a power supply like mine? Mounted elsewhere?

Yeah mine is running. All my power supplies are down under the servo motor in a case. Guess they put them in different places over the years. Mine's a 2004 10/12 with AC heads. There's probably a way to bypass the safety beams by looping one of the contacts. I'm sure the optical gate breaks continuity when it trips.

Thanks again for the pic its helped alot, pretty sure we need 2 4 wire optical sensors with blue black white brown wires. Hopefully after we Replace all six worn out stroke cylinders and get sensors installed we will be up and running......

If you are buying new sensors make sure to look as to whether they need to be PNP -or- NPN

Perhaps musterebom could tell you what his are?

Here is a link to a good article about "sinking" and "sourcing"

That machine guy, looks like I have got some more research to do before buying sensors thanks for bring this to my attention. Anyone that has this press know if it is PNP or NPN type sensors?

Yeah, I was going to say it doesn't do a whole lot of good unless he knows what they do when they switch. Could be as easy as looping a piece of wire in there to bypass the sensors. I'll have to get up on top of the press and have someone index it and trip the sensor while I probe it with a multimeter in order to be sure. I'm in FL on vacation now though so it'll have to wait but I'll do it!
