Lithrone 540+ electrical problem

[brunolobo]

Hello dear collegues !I have a Lithrone 540+c and some errors starts to show up on the press station these are the errors: FDUC Communication error S002C
- PDUC 1 Communication error S0020, - PDCU 2 Communication error S0021, . PDCU 3 Communication error S0022.

When these errors appear the damp rollers are out of control(running very slow) and i'm not able to operate the amr for side lay and suction head on feeder.

Trying to reset the system i turned off the PQC as well as the Press on main power and got it to be ok but these errors come back .I hope that someone can help us!Any idea will be welcome.

Cheers !! Bruno Lobo

This is like the same problem ive experienced with the CD-74, if you have communication problems you should first check all the connections, but probably the problem will be a main board, usually when you have communication problems its because this machines have 2 parallel circuits one main and other one that checks the first, so if one of the circuits doesnt check the other one the machine stops, so i guess you should try to find a bad connection first, and if that doesnt work try to find the module or board that may be damages, usually this electronic things go off when you have a lot of noise in your electric system, you should check that too.
