Hi sir:
1) Problem the locking valve Y 315 is lack for +42 Vdc is missing. look for connector 6.8
2) test in the connector 6.8 for +42 Vdc for locking valve.
3) Check continuity with the cables for connector.
4)check the resistance for coil of locking valve Y 315.
5) If everything is o.k test the Electronic boards: IAR - AR.

Thank's for your quick answer Mr. Chock.
First i must correct machine model, it's a 92EM. In this case, the error would be similar to the 76.
I checked for issues with the y315 valve, and everything seemed ok.
I noticed that, in the IAR board, the red LED that signs the supply to the y315 was off.
So, i tested the IAR and AR boards on other machine, when i switched, only, the AR board, the error 84 was shown on this other cutter.
I think you're right....AR board is not ok.
I'll be back to you, if you don't mind of course....
All the best...
