I have enabled (by mistake) 3 position enabling device and mode selection in input settings of the UR robot e-series. Now the robot starts in Automatic mode and doesn't allow to go into Manual mode. It says "it is currently controlled by the operational mode safety input".  How can I reset the input settings?

I’m not sure if there is a way to get into it to correct this other than wiring something to that input. You could simply wire a switch into the input that goes high, you will need to wire it to both inputs as it’s safety and is looking for a pair of signals.
