| Component | Wire Color | Function | Notes |
|---|---|---|---|
| Transmitter | Red | DC12-24V Positive Power Supply | Connect to power supply positive terminal |
| Transmitter | Black | Ground (GND) | Connect to power supply negative terminal |
| Transmitter | Green | Reserve | No need for connection in basic use |
| Transmitter | Yellow | Reserve | No need for connection in basic use |
| Transmitter | White | Reserve | No need for connection in basic use |
| Receiver | Red | DC12-24V Positive Power Supply | Same as transmitter power connection |
| Receiver | Black | Ground (GND) | Same as transmitter ground connection |
| Receiver | Green | NO/NC Output (Default NO) | Connect to material handling/door control system signal input |
| Receiver | Yellow | Configurable NC | Activate via Blanking Mode setup |
| Receiver | White | COM (Common Terminal) | Matching terminal for NO/NC output |
| Fault Symptoms | Possible Causes | Solutions |
|---|---|---|
| Receiver's blue light flashes after power-on | Emitter and receiver are misaligned | Readjust the position of both units to ensure parallel alignment |
| Transmitter's red light flashes fast | Power supply voltage <9V or >28V | Check and stabilize the power supply to meet DC12-24V requirements |
| Light curtain works normally, but no safety action (equipment/door) | Wiring error | Recheck wiring against the Wiring Guide; ensure NO/NC is connected to the correct control signal terminal |
| Unable to enter Blanking Mode | 1. Light leakage during door descent 2. Bottommost beam blocked by debris/materials 3. Door/obstruction fails to meet minimum continuous blocking distance | 1. Fix door sealing to prevent light leakage 2. Clear debris or materials blocking the beam 3. Adjust door or obstruction to meet continuous blocking distance requirements |
