Right but the bot did not fault out and even tripping the light curtain would not stop it, only way to stop it was to kill the power. We have it programmed so if the light curtain is tripped it also faults the robot out because operators in the past would trip the curtain on accident when the bot was close to the tool and then they would home it and on the way home it would crash into the tool, so now when the curtain is tripped we need to manually move the bot away from the tool reset the fault and then home it.
