Yes sorry, it is 1F.

Guys i just find out where is the problem with Fault 72. Unfortunately, I don't know why, but replacing the control unit will solve this problem. Elsewhere on the forum, I read that the parallel card can also be defective - I have it all right after all. As part of the claim, I received a new control unit from the dealer and the problem disappeared. All the theories about wire lengths and such can have an effect, but if you are sure of the wiring and still have this problem, it needs a new unit. Hopefully I can help someone. The new version of the unit has a 1mF/5.5V capacitor. I'll send a photo.

Well I upgraded firmware but it did not helped. Anyone new to the problem?

I need this CPU versions. Please can anybody help and share with me firmware 74.01?
