Troubleshooting procedure

Universal Robots are aware that the graphical interface of the Polyscope operating system can in
some rare instances freeze and become inoperable.
These issues can be caused by a hardware defect in either the teach pendant or safety control
board, or by a software issues.
First make sure that the system is operating with the latest Polyscope software versions and the SD
card is mounting correctly. Make sure that no URCaps or processor loading programs are not
running. To be sure a new image a can be written. If the issues are gone after this procedure, the
problem can be related to software. Please continue with a MyUR support ticket.
To troubleshoot and isolate this issue into a single failing part. It is recommended to mount another
teach pendant in the controller box that is experiencing issues, or mounting the teach pendant from
the failing system in controller box that has been confirmed to operate without issues.
If this this not possible, a second test can be conducted to isolate the issue to either the Teach
Pendant or Safety Control Board.
Mount a USB wired keyboard with LED indicators in the USB port of the controller box. (Not the USB
port of the teach pendant.
Then press one of the keys on the keyboard that will activate one of the LED indicators. (E.g. the
NumLock key)
