What to do if the LED does not light up on my SICK GPS?
- JJonathan EvansAug 4, 2025
If the LED on your SICK GPS isn't lighting up, it could be due to a few reasons. First, check if something is blocking the beam's path and remove the obstruction. Next, ensure the photoelectric sensor is properly aligned with the reflector; if not, readjust it. Also, verify that the S1 signal ground switch is set to GND. Make sure all wires are correctly attached in the terminal block. If none of these steps work, the photoelectric sensor might be defective and need replacement.
