SM52-4 automatic feeder pile not working

hi,
sm52-4 high pile, cp2000
anyone can help please., problem with the automatic pile feeder is not working. even i already clean all the sensors.

regards,

 

Start by checking all connections on the limit switches, at both ends.

 

How to check the limit switch ?
I already check all and it seems everything is fine.

 

I always start with the simple things, like at the bottom of the electrical cabinet beside the feeder. Look at the plugs and make sure everything is pluged in and not damaged. Then one person to enguage the limit and you watch at the cp tronic screen and make sure the computor sees the switch. Keep me posted

Hi..when you run the presswith feeder running the lifting suckers trigger the table lift.if you take the cover off the feed head you will see asmall sensor.this works with one of the lifting suckers to time the lift until the foot stops the stack rising..the problem may be the sucker but probably the sensor..do you have a local press which you can swap/test the parts?
