Photoelectric Safety Device for Automated Doors with Blanking Mode Function

Core Specifications (Detailed Parameter Table)

Key Functions & Advantages (Clear, Detailed Points)

1. Blanking Mode: Anti-False Alarm for Automated Doors

• Mode Definition: Specifically designed for automated door gaps—blocking the first channel of the light grid will not trigger safety responses, adapting to the structural characteristics of automated doors (e.g., roller shutters, fast doors) where sequential beam blocking occurs during normal closure.
• Activation Logic: Avoids unnecessary door reversal or stopping caused by door panels themselves during operation, balancing safety and operational efficiency.
• Setup Convenience: Simple wire-touch operation (no professional tools required), ensuring quick adaptation to different automated door types.

2. Targeted Anti-Pinch Protection

• Precise Detection: 8-beam light grid covers the full height of automated doors (1729mm), detecting hands, limbs, small tools, or goods near the door to prevent pinching/crushing accidents.
• Instant Response: Triggers safety signals immediately upon beam interruption, matching the fast operation of automated doors to eliminate safety lags.
• Wide Adaptability: Suitable for various automated door types (fast doors, roller shutter doors, automatic swing doors, industrial sectional doors) in different scenarios.

3. Rugged & Reliable Performance

• IP67 Protection: Fully dustproof and waterproof, withstanding temporary water immersion, heavy dust, and industrial contaminants—ideal for outdoor-installed automated doors or dusty workshop environments.
• Temperature Resilience: Operates stably from -20°C to +60°C, adapting to cold storage automated doors, high-temperature workshop doors, and outdoor doors exposed to seasonal fluctuations.
• Durable Structure: Aluminum alloy housing resists mechanical wear, vibration, and corrosion, ensuring long-term reliability even with frequent automated door operations.

4. Easy Installation & Intuitive Operation

• Color-Coded Wiring: Clear wire function division simplifies connection to automated door control systems (details in Wiring Guide below), reducing installation errors.
• Adjustable Mounting: Reserved installation holes with standardized dimensions enable flexible mounting on different door frames (vertical installation recommended).
• Visual Diagnostics: LED indicators on both emitter and receiver provide real-time status feedback, allowing on-site personnel to quickly identify normal operation, misalignment, voltage issues, or blockages.

Wiring Guide (Standardized Table with Notes)

Critical Warnings

• Do NOT connect NO/NC terminals (Green/Yellow wires of receiver) to the power supply positive terminal—this will permanently damage the optical relay.
• Ensure wiring is tight and free of short circuits; keep cables away from high-voltage/high-current conductors to avoid interference.

Blanking Mode Activation Steps (Step-by-Step)

1. Complete wiring according to the Wiring Guide and confirm no connection errors.
2. Power on the photoelectric safety device (ensure 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 rapidly—this indicates successful activation: Yellow wire switches to NC mode, and Blanking Mode is enabled.
5. After activation, test the function: Normal door closure (blocking the first channel) will not trigger safety responses; intrusion of personnel/objects (blocking other channels) will trigger immediate door reversal/stopping.

Application Scenarios (Targeted, Detailed List)

• Industrial Automated Doors: Fast doors, roller shutter doors, sectional industrial doors (factories, warehouses, logistics centers).
• Commercial Automated Doors: Automatic swing doors, sliding doors (shopping malls, office buildings, retail stores).
• Special Environment Automated Doors: Cold storage automated doors, clean room fast doors, outdoor automated doors (resistant to temperature extremes, dust, and moisture).
• Logistics/Loading Dock Doors: Automated loading dock doors, material transfer area doors (protects personnel and goods during high-frequency operations).

Troubleshooting (Comprehensive Problem-Solution Table)

Installation Guidelines (Detailed, Operable Steps)

1. Pre-Installation Preparation:
   • Confirm the automated door’s opening height and width—ensure the device’s protection height (1729mm) and operating range (1-8m) match.
   • Check the power supply: Prepare a stable DC12-24V power source (compatible with the device’s working voltage).
   • Inspect the device: Verify that the emitter, receiver, cables, and connectors are intact (no damage or loose connections).
2. Mounting Operation:
   • Select mounting positions: Install the emitter and receiver vertically on both sides of the automated door frame, ensuring the light grid is parallel to the door’s movement direction and covers the full door opening (no blind spots).
   • Use installation holes: Align the device’s mounting holes with the door frame, fix with matching screws (ensure firm installation to avoid vibration-induced misalignment).
   • Cable arrangement: Route the 8m (transmitter) and 4m (receiver) cables along the door frame, avoiding sharp edges or high-pressure areas (prevent cable damage).
3. Wiring & Debugging:
   • Follow the Wiring Guide to connect power, ground, and signal cables—double-check to avoid reversing positive/negative or connecting NO/NC to power positive.
   • Power on the device: Observe LED indicators—transmitter’s steady blue light and receiver’s steady blue light indicate normal power-on.
   • Align the light grid: If the receiver’s blue light flashes, adjust the emitter/receiver positions until the light is steady (beam alignment successful).
   • Activate Blanking Mode: Complete the wire-touch activation steps as instructed to adapt to the automated door’s operation.

Usage & Maintenance Caveats (Detailed Reminders)

• Cable Protection: Keep connecting cables away from high-voltage/high-current conductors, door machinery, or forklift paths to avoid interference, extrusion, or damage.
• 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 (avoids false triggers or detection failure).
• Blanking Mode Usage: Ensure the door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement (follow the user manual’s specifications).
• Temperature Adaptation: In extreme environments (e.g., cold storage below -20°C or high-temperature workshops above +60°C), confirm the device’s operating temperature range before use.
• Regular Inspection: Periodically test the anti-pinch and Blanking Mode functions to ensure the device works normally; check wiring tightness and connector integrity.
