KBA Rapida 104

I have trouble with my offset machine.
The machine doesn't work the plates change and the language is in german after the PLC battery fault.
The technician changed the battery and set the correct language but the plate change doesn't work properly.
The machine doesn't stop at the correct points to insert the plates.
What is the setting procedure to set up the machine for the plate change?
Please contact me at raulfelic@gmail.com who can help me to fix it.

Thanks
