Man Roland 304/ UWR: station 2,invalid data input.

Dear Freinds,

After turning on the machine and the air is released, green lights on the buttons turn on, when i push any putton for turn the machine, first push 3 beeps rings and the second push machine don't turn and 3 beeps ring again. i attach some photo for the error message.
The 7-segment display on the A358 in +AX shows 7 0

Please a hep.

 

Station 14 is coating unit, station 2 is delivery.
First change relay boards from sps rack,take them from unit 1 or 2.
Change relay board in UWR(A358)
Then check connection between last printing unit and coating unit. If that does not help call technitian to check SPS stations with RODIMO program.

 

Thank you for your reply.

The problem was a broken board at delivery unit +EA cabinet rack -A353.
See attached photos.

 

Relay board...

 

If you check the other boards, they all have a cooler, except for the EA board, if you can adapt a cooler of the same brand as the fans of the other boards, there is a source that the heatsink is heated by, it is under the relay card.

 

Thank you Daniel
