If you open any door or cover, or one in particular? Each safety switch has two circuits, one for safety circuit and one for diagnostics.

Did you tried to adjust the safety switches?

Haii all,

I already solved the problem. It was the cable to the main panel was bite by rat.
The main panel door is the right side.
