Safety Light Grid for Rolling Doors and High Speed Doors with Blanking Mode Function 0


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)

  1. Power on the device.
  2. Within 1 minute, touch the receiver’s Green wire to GND five times (Red light blinks to confirm).
  3. 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.
