Product Description
Safety Light Grid for Rolling Doors and High Speed Doors with Blanking Mode Function
Product Overview
JUTAI CL20-8L Safety Light Grid is a specialized protective device for rolling doors and high speed doors, featuring Blanking Mode to avoid false alarms. It forms an 8-beam invisible grid, triggering instant safety responses (door reversal/stopping) when intruded, ensuring anti-pinch protection in industrial/commercial settings. With IP67 protection and rugged aluminum alloy housing, it's durable for harsh environments.

Key Features
- Blanking Mode: Prevents false alarms during normal door closure, adapting to rolling/high speed door gaps.
- Rapid Response: Matches high speed door operation, triggering instant safety actions to avoid accidents.
- IP67 Durability: Resists water, dust, and industrial contaminants for outdoor/harsh environment use.
- Comprehensive Coverage: 1729mm protection height eliminates safety blind spots for wide door openings.
- Easy Integration: Standard connectors and color-coded cables simplify wiring.
Wiring Configuration
| Component | Wire Color | Function |
|---|---|---|
| Transmitter/Receiver | Red | DC12-24V Positive Power Supply |
| Transmitter/Receiver | Black | Ground (GND) |
| Receiver | Green | NO/NC Output (Default NO) |
| Receiver | White | COM (Common Terminal) |
| Receiver | Yellow | Configurable NC (via Blanking Mode setup) |
Blanking Mode Setup
- Power on the device.
- Within 1 minute, touch the receiver's Green wire to GND five times (Red light blinks to confirm).
- Yellow wire switches to NC mode; Blanking Mode is activated.
Primary Applications
- Rolling doors (industrial, retail, warehouse)
- High speed doors (manufacturing plants, logistics centers)
- Sectional rolling doors (factories, large warehouses)
- Commercial storage facility rolling doors
Troubleshooting Guide
| Fault Symptoms | Solutions |
|---|---|
| Slow Flashing Lights (Power On) | Realign emitter and receiver for precise beam alignment. |
| Fast-Flashing Red Light (Transmitter) | Check power supply (ensure voltage is 9V-28V). |
| No Anti-Pinch Action (Light Grid Normal) | Verify wiring (avoid connecting NO/NC to power supply positive terminal). |
| Unable To Enter Blanking Mode | 1. Fix light leakage during door descent. 2. Clear debris blocking the bottommost beam. 3. Ensure door/obstruction meets minimum continuous blocking distance. |
Usage Guidelines
- Keep cables away from high-voltage conductors and door machinery.
- Regularly wipe lenses with a dry, soft cloth to remove dust/debris.
- Do not bend/twist the device or cables; avoid direct sunlight on the receiver.
- Avoid scratching infrared lenses to maintain detection accuracy.
