Product Overview
JUTAI CL20-8L Safety Light Grid installed on industrial door

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.

  • Sectional rolling doors (factories, large warehouses)
  • Commercial storage facility rolling doors
Troubleshooting Guide
Fault SymptomsSolutions
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 Mode1. 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.
