I have a customer With a UR10e, Polyscope Ver 5.12. We have done some Wiring modifications to the Safety (added a Pressure floormat into the Safeguard Stop) and all tested fine. Now when Powered on in **Remote**. The Robot reports an alarm C50A0: Robot powerup issue If I switch to Manual mode the fault still persists. However If I power on whilst in **Manual** mode the Fault does not appear and I can swap to Remote and run the program fine. I have removed all Estops, safeguard stop and replaced with links and still the same fault! Does anyone have any ideas? ---

I have found out the problem was not Hardware related but the Installation file Somehow I think the Installation file had become corrupted. when I tried a Default file the issue dissapeared. ---
