This article is for robots running PolyScope X. If your robot runs PolyScope 5, see Troubleshooting C203A0 Safety Settings Mismatch (PolyScope 5).
If fault C203A0 appears after a Beacon URCap install or update, this is expected — this article will fix it.

Fix the Fault
Make sure the correct Beacon program for your application is loaded before you start. These steps apply safety settings to the program that's loaded now. If the wrong program is loaded, the fault won't clear.
If your robot runs welding, see How to Set the Startup Program for Beacon Welding (PolyScope X).
If it runs cutting, see How to Set the Startup Program for Beacon Cutting (PolyScope X).
The whole fix happens on the Safety screen. Unlock it with the safety password, apply the new settings, then reload.
Tap OK to dismiss the fault.
Tap Application. Then tap Safety.
Under Safety I/O, tap Inputs. Then tap Unlock.
Enter the safety password (
ursafe). Then tap Confirm.
In the Wired Inputs section, find the CI6 / CI7 signal pair. Tap it. Assign the value Freedrive Enabled Input.
Tap Apply.
Tap Apply and restart. This reloads the application. The robot keeps running.
Tap Confirm Configuration.
Open the menu, then tap Reload.
Tap Reload to confirm.
How to Verify
After the reload, fault C203A0 should not appear. The robot arm starts up normally. You can run programs normally.
