Heidelberg SM 52 delivery table not coming up

Hi everyone I was asking for help on my SM52 delivery table is only going down and will not come up after changing piles has anyone encountered this and would be so kind and point me in direct what to look for or where the problem comes from I have checked all the limit switches are working OK switched the machine off and on few times but problem does not clear .Will appreciate some help .

 

Hello dear sir, look inside the reception. On the CE service side and the CS training side there is a cell on each side, please clean them. I think it will be ok

 

Check the delivery back-stop bar isn't stuck in its upper position. If it is, just pull it down and it'll drop into the normal lower position, allowing the table to be raised.

Thanks I tried and still not working

 

This is on a sm 52 low pile delivery i will check it out thanks Steve

 

At operater side check ´delivery back-stop bar´maybe it stuck and mostly is dirty. Clean and check.
At both side there is one sensor, with glass lense - clean every day.

 

Thanks for the help.i located the sensors much appreciated
