we are facing an issue with Staubli cs8c robot controller.
on RSI display it is showing "U" error message and ARPS 12v2 is LED not showing and as per the manual we have connected pendant to restart the robot arm but no changes.
upon connected the pendant,, it is showing "emergency stop chain miss wired for signal MCPES2" on the pendant display.
We have checked all the remaining connection cablings to all the emergency switches like.. UESB1 and 2, Door1 and 2, USEA1 and 2(shoted), USEREN1and2 (shorted).
In terminal USEB1 + and - 24 voltage
Terminal USEB2 + and - 0v
Door1 + and - 24v volt
Door2 + and - 0 volt.
could you please help me for this issue.
