Heidelberg SORM delivery unit

[Raituss]

Hello!
I'm first here. I have a problem with delivery unit on my SORM.
It does not want to lower the table while printing. Have to do it manually.

I don't really know on what principle it works. Some guy tells me that there is some photoelectric sensor. But I'm not sure.
Thanks if you can help with advice.

Roller switch running on feeder hoist chain, under top feeder cover, gear side. This roller switch rides on the lobes of the chain, with NO and NC sets of contacts fire the relay to lower chain. Star cam on pile hoist shaft, under OS cover, limits amount of movement.
