KUKA ROBOT - Can't Motor On After activate safety space

Hi expert !

i have a question like this

before, when i work with this robot, i see the safety space was activated and work well

but, today when i return, someone disable option and i have to choose safety monitoring as the picture to activate

but after choosing, i can't press motor on, and on HMI notify that the config error (sorry i couldn't take a photo )

i think there is something PLC need to do but i don't really know

plz tell me if you know the problem

bonus:

when i change like this, the error disappear and i can motor on normally.

Did you confirm the new configuration on the robot?

-that's it. how can i do it ,

i really don't know

thanks, i got it
