Status keys configuration

Hello,

I have made a new project in Work visual 4.0 with an ESAB 4004i pulse power scource. Connected inputs and outputs, and when I trigger output 4 wire feed works, but status keys for forward/backward wire are grey(inactive).

Maybe someone know what I could have missed?

I'm so embarrassed right now, how I didn't thought of pressing the enabling switch. Thank you.
