What to do if the green LED is not lit up on my Pepperl+Fuchs UC-18GS?

If the green LED on your Pepperl+Fuchs accessory isn't lit, here's what you should check: * First, ensure the power supply is on. If it's off due to maintenance or installation, switch it back on. * Next, verify the plug is securely connected to the sensor and the cap nut is tightened. * Inspect the wiring in the splitter or switch cabinet for any errors and correct them. * Finally, check the supply cable to the sensor for damage and replace it if necessary.
