Industrial Door Protection Light Grid with CE Certification & IP67 Enclosure

Core Specifications (Detailed Parameter Table)

Key Functions & Advantages (Clear, Detailed Points)

1. CE Certification & Safety Compliance

• Meets international safety standards for industrial machinery, ensuring compliance with workplace safety regulations in global industrial settings.
• Rigorously tested for reliability and safety, providing legal and practical protection for industrial door operations.

2. IP67 Enclosure for Harsh Environments

• Fully dustproof and waterproof, withstanding temporary water immersion, heavy dust, and industrial contaminants—ideal for outdoor-installed industrial doors, dusty workshops, or humid environments.
• Aluminum alloy enclosure resists mechanical wear, vibration, and corrosion, adapting to high-frequency industrial door operations and harsh working conditions.

3. Targeted Industrial Door Protection

• 8-beam light grid covers the full height of industrial doors (1729mm), eliminating safety blind spots and accurately detecting hands, limbs, tools, or goods to prevent pinching/crushing accidents.
• Instant response to beam interruption, matching the operational speed of industrial doors (fast doors, roller shutters) to avoid safety lags.

4. Blanking Mode for False Alarm Prevention

• Specialized for industrial door gaps: Blocking the first channel of the light grid does not trigger safety responses, adapting to sequential beam blocking during normal door closure.
• Avoids unnecessary operational interruptions while retaining full protection against unintended intrusions, balancing safety and efficiency.

5. Easy Installation & Intuitive Operation

• Color-coded wiring simplifies connection to industrial door control systems, reducing installation errors (details in Wiring Guide).
• Standardized installation holes enable flexible mounting on various industrial door frames, ensuring firm fixation and stable operation.
• LED indicators provide real-time status feedback, allowing on-site personnel to quickly identify operational issues without professional tools.

Wiring Guide (Standardized Table with Notes)

Critical Warnings

• Do NOT connect NO/NC terminals (Green/Yellow wires of the receiver) to the power supply positive terminal—this will permanently damage the optical relay.
• Keep connecting cables away from high-voltage/high-current conductors to avoid signal interference or cable damage.

Blanking Mode Activation Steps (Step-by-Step)

1. Complete wiring according to the Wiring Guide and confirm no connection errors.
2. Power on the light grid (ensure the power supply meets DC12-24V requirements).
3. Within 1 minute of power-on, touch the receiver’s Green wire (NO output) to its Black wire (GND) five consecutive times.
4. Observe the receiver’s Red light blinking—this indicates successful activation: The Yellow wire switches to NC mode, and Blanking Mode is enabled.
5. Test the function: Normal door closure (blocking the first channel) will not trigger safety responses; intrusion of personnel/objects will trigger immediate door reversal/stopping.

Application Scenarios (Targeted, Detailed List)

• Industrial Fast Doors: High-speed roll-up doors in factories, logistics centers, and production lines.
• Roller Shutter Doors: Industrial roller shutters in warehouses, workshops, and loading docks.
• Sectional Industrial Doors: Large industrial doors in factories, storage facilities, and industrial parks.
• Special Environment Industrial Doors: Cold storage industrial doors, outdoor industrial doors, and dusty workshop doors (resistant to temperature extremes, dust, and moisture).

Troubleshooting (Comprehensive Problem-Solution Table)

Installation Guidelines (Detailed, Operable Steps)

1. Pre-Installation Preparation:
   • Confirm the industrial door’s opening height and width—ensure the light grid’s protection height (1729mm) and operating range (1-8m) match.
   • Prepare a stable DC12-24V power supply and check the device for intact components (no damaged cables or connectors).
2. Mounting Operation:
   • Install the emitter and receiver vertically on both sides of the industrial door frame, ensuring the light grid covers the full door opening without blind spots.
   • Align the device’s installation holes with the door frame, fix with matching screws (ensure firm installation to resist door vibration).
   • Route the 8m (transmitter) and 4m (receiver) cables along the door frame, avoiding sharp edges or high-pressure areas.
3. Wiring & Debugging:
   • Follow the Wiring Guide to connect power, ground, and signal cables—double-check to avoid positive/negative reversal or incorrect output terminal connections.
   • Power on the device: Confirm the transmitter’s steady blue light and receiver’s steady blue light (normal power-on).
   • Align the light grid: If the receiver’s blue light flashes, adjust the emitter/receiver positions until the light stabilizes.
   • Activate Blanking Mode as instructed and test the anti-pinch function to ensure normal operation.

Usage & Maintenance Caveats (Detailed Reminders)

• Cable Protection: Keep cables away from high-voltage conductors, door machinery, and forklift paths to avoid extrusion, damage, or interference.
• Lens Maintenance: Regularly wipe the emitter/receiver lenses with a dry, soft cloth to remove dust, oil stains, or condensation—dirty lenses will affect detection accuracy.
• Physical Protection: Do not bend, twist, or drop the device; avoid scratching the aluminum alloy housing or infrared lenses.
• Light Source Avoidance: Prevent direct sunlight or other infrared light sources from shining on the receiver to avoid false triggers.
• Blanking Mode Usage: Ensure the door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement.
• Regular Inspection: Periodically test the anti-pinch and Blanking Mode functions; check wiring tightness and connector integrity to ensure long-term reliability.
