Sormz machine feeder auto stop problem

Dear sir,
Peace be upon you. I hope you are doing well. I am using weko old model impression box 1979. The feeder of this machine is not auto closing. What can I do in this case? Please someone help.

 

Does the barrier snap into the down position but yet, the machine pulls the sheet through? Do you see and hear the electromechanical functions operating normally?

 

The sheet pulls despite the obstruction. The impression is not cut. Impression is turned on when the feeder is running with the sheet.

 

Manual operation OK Feeder and impression. Auto impression and feeder not cut with light barrier.
Weko old box
How can I solve this problem?

 

J'ai le même problème, peux-tu poster des photos du schéma électrique ?

 

Please put a clear picture of the card that I put a picture of so that the components are clear because my card was damaged
