Polar 76EM error 84

Hello friends,
Anyone have a clue about error 84?
It started to happen one time after other and nothing happens, only the error is on the display ....

Best regards

 

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.

Blessing

 

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...

 

ok sir
Please do that i did indicate.
Let me know, please
Blessing
