Gammerler 501/1 issue

[JHM]

We have a old Gammerler 501/1 that we're trying to get going. I'm not able to keep it running it keeps shutting down and these errors keep showing up on the display. I'm not familiar with Gammerler stacker's. Any info would be appreciated!
Thanks JHM

Hi sir ;

You must clean the Valve 19Y3 or replace it if there faulty , and limit switch, if the valve is electrical, see if there are voltage +dirty , and see the valve is Electro'Pneumatic, see if there are sticking, dirty or leaking, lack of voltage in their terminal valve 19Y3.

The limit switch, can be out of adjustment, adjustment, clean it, and tight every wires of L.W and see if there are voltage according with his schematic diagrams

However you must see if there are sensors , if there , please clean, and test it.
