Sm 52-2 locked reversal

Have a speed sm 52-2 and did maintenance on cromomatic rolls , but when coach replaced back the machine was configured to print with reverse ( 1x1) and does not change anymore, was blocked. Resetou and have tried many ways to fix and nothing . Has anyone seen that? Tanks and sorry the english...

 

This may be something we might be able to help you with but your going to have to find a better way to describe your issue in english. Thanks

 

I think he is saying that the perfector is blocked from changing over. maybe a dirty senor eye? is soiled during cleaning.

 

Thanks for the help jmt. The SM52 has a fully automatic perfecter and i could produce a list as long as my arm for reasons the changeover is blocked. helpful would be at what point during the changeover it becomes blocked, error codes, does it go to perfect and not to straight, more details needed. This can be difficult to troubleshoot while onsite let alone in an online forum with little to no details.

 

Yes jmt. perfector not changing.

 

The manager of Heidelberg's been here for two days and nothing to solve. The machine was adjusted manually to print front / front but the CP-Tronic command does not change. All sensors and boards have been conferred by him and nothing to solve.

 

If you can somehow put a video of the machine attempting a changeover from straight to perfect i may be able to see at what point the press aborts the changeover. Maybe you can put something up on youtube. Make sure its an attempt from straight to perfect

 

What is the error that comes up while trying to change over to perfecting?

 

Appears on the screen 3 symbols flashing: 01 is the configuration of the sign (#) , 02 asking to change the 1x1 to 2x0 perfect color and 03 the 2-cylinder symbol with a dash in between. Translation by google .

 

Another detail : When you arrive at this screen, the machine lock and no longer accepts any commands . The case is being taken to Germany to study.

 

The 2 cylinders with a line through it means that you have a synchronisation error. This error only happens when your in perfect but not straight printing.
There are 2 flags on the end of both sucker bars on the storage cylinder that pass through a sensor, these flags signals must correspond to a signal on the reversing cylinder which has a disc with a sensor on the operator side. This monitors any risk of collision between both cylinders in perfect mode only. Maybe a flag has been knocked or the locking pawl on the operator side isn't moving the storage sucker bar to its correct position or it could be a sensor fault. As exheidmech said its difficult to fix on line - it needs an experienced technician on site.

 

Thanks, The coach of Heidelberg has spent three days working on this machine and nothing. So I'm trying to see if anyone in this forum has been there. All sensors were tested and the cylinders placed in the right positions.
