Safety Light Grid for Rolling Doors and High Speed Doors with Blanking Mode Function

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.

Core Specifications (Parameter Table)

Parameter	Specification
Working Voltage	DC12-24V
Working Current	Transmitter <65mA @DC12V; Receiver <20mA @DC12V
Output Configuration	NO/NC relay output (configurable)
Protection Rating	IP67 (Dustproof & Waterproof)
Housing Material	Aluminum Alloy
Operating Range	1-8 meters (transmitter to receiver)
Maximum Protection Height	1729mm
Number of Photocells	8
Cable Length	Transmitter 8m; Receiver 4m
Connector Type	Transmitter: 5-pole M8 male; Receiver: 4-pole M8 male
Operating Temperature	-20°C ~ +60°C
Special Function	Blanking Mode (first channel blocking non-trigger)
LED Status Indicators	Transmitter: Blue (normal), Red (voltage irregularity); Receiver: Red (blocked), Blue (unblocked), Flashing Blue (misalignment)

Key Features (Bullet Points)

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 (Red=Power+, Black=GND, Green=NO/NC) simplify wiring.

Wiring Guide (Table)

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 (Steps)

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 (Bullet Points)

Rolling doors (industrial, retail, warehouse)
High speed doors (manufacturing plants, logistics centers)
Sectional rolling doors (factories, large warehouses)
Commercial storage facility rolling doors

Troubleshooting (Table)

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 Caveats (Bullet Points)

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.
