Tips: How to troubleshoot when a fault occurs?

When troubleshooting the CCHN photoelectric sensor, start by confirming a stable power supply and correct wiring. Clean the lens and check alignment to remove optical interference, then use the indicator lights to pinpoint fault conditions. If problems continue, inspect the environment for strong light or electrical noise, and test with another sensor to quickly isolate the cause.
