We have a KUKA robot working with safe operation system, We need to execute the brake test but we can not change the robot mode from T1 to AUT mode as when we turn operation switch to select the operation mode, the only available option is T1 Mode. I tried by activating the start up mode but it also did not work. I am hardly stuck in this problem and I did not find my answer inside manual of SafeOperation. Our system is KSS 8.3 and SafeOperation 3.3.
Thank you in advance for your help
