A:
When the error indicator light of the safety light curtain lights up, you can quickly troubleshoot and solve it by following the steps below:
1. Confirm the fault code by checking the manual: Check the corresponding meaning of the error light according to the manual to clarify the fault type.
2. Check the optical axis status: Make sure there is no obstruction (such as foreign matter, dust, oil) between the transmitter and the receiver. Clean the window and realign the optical axis if necessary.
3. Confirm the wiring and power supply: Check whether the wiring is correct and firm, whether the power supply is stable, and eliminate problems such as looseness and broken wires.
4. Check interference factors: Check whether there is crosstalk, strong light interference or electrical interference between the light curtains, which can be improved by dislocation installation, optimized grounding, etc.
5. Reset or restart the system: After troubleshooting, some light curtains need to be powered off and restarted or reset by the controller to return to normal.
6. Check external control devices: If a safety relay or controller is connected, its status and logical configuration must also be checked.
If the above methods are ineffective, it is recommended to contact the original manufacturer or supplier technical support for further investigation.
