Safety Light Grid System for Automatic Doors with Waterproof Aluminum Housing

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.

Core Specifications (Parameter Table)

Key Function Automatic door anti-pinch protection + Blanking Mode (anti-false alarm)
LED Status Indicators Transmitter: Steady blue (normal operation); Fast-flashing red (voltage <9V or >28V)

Receiver: Steady red (object/personnel blocked); Steady blue (no obstruction); Flashing blue (first power-on, misalignment)
Installation Hole Dimensions (Unit: mm) 14, 29, 75, 80, 175, 19.7, 21.4, 259

Key Advantages (Clear Points)

1. Waterproof Aluminum Housing

  • Aluminum alloy construction ensures durability, corrosion resistance, and effective waterproofing, paired with IP67 rating.
  • Withstands rain, dust, and moisture, suitable for outdoor-installed automatic doors or humid industrial environments.

2. Targeted Automatic Door Protection

  • 8-beam light grid covers full door opening height (1729mm), eliminating safety blind spots and preventing pinching of hands, limbs, or objects.
  • Instant response to beam interruption, matching the operational speed of automatic doors to avoid safety lags.

3. Blanking Mode for False Alarm Prevention

  • Blocking the first channel does not trigger safety responses, adapting to automatic door gap structures.
  • Avoids unnecessary door reversal during normal closure while retaining protection against unintended intrusions.

4. Easy Installation & Operation

  • Color-coded wiring simplifies connection to automatic door control systems (details in Wiring Guide).
  • Adjustable mounting brackets fit various door frame structures; intuitive LED indicators enable quick status checks.

Wiring Guide (Standardized Table)

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

  1. Complete wiring and power on the system.
  2. Within 1 minute of power-on, touch the receiver’s Green wire to its GND (Black wire) five times.
  3. Receiver’s Red light blinks to confirm activation: Yellow wire switches to NC mode, Blanking Mode enabled.

Application Scenarios (Targeted List)

  • Industrial automatic doors (fast doors, roller shutter doors, sectional doors)
  • Commercial automatic doors (shopping malls, office buildings, retail stores)
  • Outdoor automatic doors (parking facilities, logistics center entrances)
  • Special environment automatic doors (cold storage, humid workshops)

Troubleshooting (Problem-Solution Table)

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
System 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

Usage & Maintenance Caveats (Key Reminders)

  • Keep cables away from high-voltage conductors and door machinery to avoid damage or interference.
  • Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust, moisture, or dirt.
  • Do not bend, twist, or pull cables forcefully; avoid scratching the aluminum housing or infrared lenses.
  • Prevent direct sunlight or infrared light sources from shining on the receiver (avoids false triggers).
  • For outdoor installation, ensure the device is fixed firmly to resist wind and vibration.
