Safety Light Curtain Working Principle
The safety light curtain forms a protective barrier through an infrared beam between the transmitter and receiver. When the beam is blocked, the device immediately triggers a safety response. This non-contact protection method is ideal for work areas requiring high-frequency access, ensuring safety without affecting work efficiency.

 

Detailed Wiring Steps

Power Connection: Confirm the operating voltage and connect the appropriate wire to the power terminal.

 

Signal Line Connection: Connect the output signal line to the corresponding interface of the control system.

 

Grounding: Ensure the device is reliably grounded to avoid interference.

 

Functional Testing: Check the indicator light status after powering on and test the blocking response.

 

Common Problem Troubleshooting

Indicator Light Not Illuminated: Check the power connection and fuse.

 

Maloperation: Adjust the installation position to avoid direct sunlight.

 

Response Delay: Clean the optical window and check the tightness of the wiring terminals.

 

Communication Abnormalities: Verify the signal line connection is correct and check the terminating resistor setting.
