Feeder Pile cannot running up on sm74-6

I need help to solve my trouble machine sm74-6.
Feeder pile cant move up. And on cptronic had sign.
I send cptronic error picture to.
Thx

 

This is top height limit. It means the safety switch is pressed and engaged. What type of Feeder your machine have? Is it Preset Feeder or Palet Pile?

 

I have a palet pile.
I was checked all switch, that is ok.
What sign on the red circle on my attachment?
I feel sign on the red circle is the problem, but i don't know what it's.

 

I was read a manual book, the sign it' mean "upper pile safety" and in wiring diagram i find switch 11S32. The prolem now is i can't find where location switch 11S32.
I try to find in sparepart book, but i can't find it.
Please help me to solve my problem, so the feeder pile can move up again.
Thx

 

My problem solved. Has hidden switch on feeder that the switch stuck.

 

Someone used continuous pile -- if you hit up button on the continuous too far up it will engage limit switch.

 

Well done, nice work
