Power panel 400 no sisplay

[Jatjag_Shah]

I have power panel 400.
Powering on with bip , but no display or display light.
How I can check with software?
I have already tried changing with new display. But same result.

Hallo Jatjag,

when I boot my PP400, I first hear a beep, and without a CF card, I get this message. If you don’t get a message, the power panel needs to be sent to B&R for repair.

Stephan
