The JUTAI CL20-8L Safety Light Grid System is a professional protective solution tailored for automatic doors, featuring a waterproof aluminum housing and IP67 protection. It forms an 8-beam invisible light grid between the emitter and receiver, instantly triggering door reversal or stopping when personnel, objects, or equipment intrude—effectively preventing pinching, crushing, or collision accidents in industrial and commercial environments.
Wiring Guide
| Component | Wire Color | Function | Notes |
| Transmitter | Red | DC12-24V Positive Power Supply | Connect to stable power supply; avoid overvoltage/undervoltage |
| Transmitter | Black | Ground (GND) | Connect to power negative terminal; ensure reliable grounding |
| Transmitter | Green/Yellow/White | Reserve | No connection required for basic use |
| Receiver | Red | DC12-24V Positive Power Supply | Same as transmitter power connection |
| Receiver | Black | Ground (GND) | Shared ground with transmitter |
| Receiver | Green | NO/NC Output (Default NO) | Connect to automatic door control system's safety signal input |
| Receiver | Yellow | Configurable NC | Activate via Blanking Mode setup |
| Receiver | White | COM (Common Terminal) | Matching terminal for NO/NC output |
Critical Warning: Do NOT connect NO/NC terminals (Green/Yellow wires of receiver) to the power supply positive terminal—this will damage the optical relay.
Blanking Mode Activation Steps
- Complete wiring and power on the system.
- Within 1 minute of power-on, touch the receiver's Green wire to its GND (Black wire) five times.
- Receiver's Red light blinks to confirm activation: Yellow wire switches to NC mode, Blanking Mode enabled.
