Kuka Krc2 drives contactor off, intermediate circuit loaded at auto

Hello everyone I am using kuka krc2 controller, when I start robot at t1 mode I can start and move it. But when I change it to the auto mode I press the I button(Img 1 Red Circle) and it doesnt turn green on the screen and gives me drives contactor off, intermediate circuit loaded error(Img 2). If you have suggestions I would be glad to hear about it.

Actually yes thank you for the response I have changed the KCP and it worked well. I had been trying all the possibilities and changing the KCP never came to my mind again thank you.
