Komori LS640 PDUC communication Error

[Darshana]

When the machine is in running mode, the PDUC communication error occurs in these units at the same time and the machine stops(PDUC 1, PDUC 2, PDUC 3, PDUC Coater 1, FDUC). But the error in DDUC 1 does not occur. Please see the pictures.
After that, the power supply of the machine must be turned off & on many times to clear this error.
What could be the reason for this?

We had similar problems with our Komori lithrone 28. The problem was a faulty circuit board that controls the water pan rollers, in the electrical cabinet. Our circuit board model was AAXDE00130. We paid about 2000 euros for a new one, and replaced it ourselves.

Of course i cannot guarantee that you issue is the same, but i would make sure the circuit board is working properly.

Our board model is the same. But there is no spare board at the moment. A new one has been ordered.
