What does 380 mean?

This alarm on Fanuc Series 0i-D/0i Mate-D indicates an LED disconnection within a separate (external) detector connected via an SDU (Separate Detector Interface Unit). This points to an internal failure of the detector's optical components.

• Internal failure of the external detector's LED component.
• Degradation of the external detector's optical system.

Click steps to track your progress.
