| 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 (power-on) | Emitter and receiver misalignment | Readjust positions to ensure parallel alignment |
| Transmitter's red light flashes fast | Power supply voltage <9V or >28V | Stabilize power supply to meet DC12-24V requirements |
| Sensor grid works, but door has no anti-pinch action | Wiring error | Recheck wiring against the guide; ensure correct connection to door control system |
| Unable to enter Blanking Mode | 1. Light leakage during door descent 2. Bottommost beam blocked by debris 3. Door/obstruction fails to meet minimum continuous blocking distance | 1. Fix door sealing to prevent light leakage 2. Clear debris blocking the beam 3. Adjust door/obstruction to meet distance requirements |
