Polar Mohr 76 EM error 69 and english manual

[Buntpapier]

If the voltages -12VB and -30VB are o. k. even after switching off the machine I would change the EI board. We measure the voltages write at the board. There are some measurement points. But the result should be the same. The EI board is as well in bigger EMC II machines. There was one EI board only. Maybe you can try a board from an other cutter first.

I solved this problem with a EAI board replacement. But if you have rom ics and 8255 it is possible with a replacement this ics you can solve your problem. If the -12 and -30 volts already done.

Hi kazimates
Good news are always good. Perfect.
I cannot fix boards. I am working in Germany and here it is forbidden to fix boards, because of safety law.
At least your machine is working again.
Thanks for feedback and take care

Dear Buntpapier,
Of course we repair the machine with given instructions. It works 2 weeks periods and after that machine gives a problem on display pcb. I am still waiting the card from the United Kingdom now.
For about the forbidden word of course the manufacturer or local authority can be say this word because you have a certified technicians already there and you cand the certified technical person very easily. But for the Turkish Republic of Northern Cyprus we can't do that because we are small island and we haven't got too much machine here. For this reason I must repair the cards with a component replacement. On the other hand Polar company can't supply softwares for the ics or schematic diagrams to us and when the machine gives the probelm to us it takes too lond period for the repair.
We are unlucky
If i have a choose of course i can replace but i don't have spare card here.

Best regards,
Kazim ATES

Hi Kazim
Oh, I understand your position. I work sometimes in areas where I have to improvise as well. I am just a bit concerned, because it is a cutter.
Parallel to Heidelberg are other sources for parts available. If you know a reliable supplier the cost is much less.
Good luck for the next fix
