Laser safety circuit is still open: Ensure laser safety before the robot program is resumed

Kuka · LaserTech 3.1

What does SikContactOpen mean?

The laser safety circuit remains open, preventing safe laser operation. This could be due to an actual open safety interlock or a mismatch between the light path settings in the laser and the requested light path configuration.

Repair Steps

  1. 1

    Inspect all components of the laser safety circuit (e.g., safety doors, light barriers, emergency stops) to ensure they are closed and functional.

  2. 2

    Verify that the light path settings configured in the laser system match the light path requested by the robot program.
