Hi pros,A connector connected to a sensor that is connected directly into our UR robot controller got pulled out. When it got damaged, we believe the connections may have shorten for a small amount of time. So we replaced the sensor and connections and when we tried to get back up and running we had an error saying that there was no 24VDC supplied to the safety board. After discussing this with some other people we ended up hooking an external 24VDC power supply to the IO power alimentation and now it works but we were told that we would need to replace the entire safety control board which is quite expensive. It just does not make sense to me that there is no fuse that can be replaced that are protecting the IOs. I am guessing since this is quite basic someone else ran into this problem. What did you guys ended up doing? Is UR replacing this under warranty?In the futur we will definitively do some modifications to the controller to protect this but with the price we pay for the robots I would expect it to be better protected against IOs shortages.
