The JUTAI Dual Channels Traffic Detector (LD-200/202) is designed to detect vehicles and provide reliable traffic monitoring for parking access control systems.

• Compact Design: Well-engineered housing for easy integration into existing systems
• Comprehensive Diagnostics: Accurate diagnosis of loop and installation problems
• Selectable Presence Time: Output can be limited to fixed time while vehicle remains on loop
• Frequency Management: Eliminate interference between adjacent loops with frequency settings
• Direction Detection: CH1 to CH2 movement triggers CH1 relay; CH2 to CH1 triggers CH2 relay
• Sensitivity Control: Adjustable via 7-way and 10-way dip switch settings

The LD-200 series detector may be configured for any one of the following modes:

• Presence Mode
• Pulse Mode
• AB Logic Presence Mode (Barrier Operation)
• AB Logic Pulse Mode (Counting Logic)

• Automatic Gate Systems
• Traffic Light Control
• Gate Drive Mechanisms
• Operating Barriers
• Parking Guidance Systems
• Activating Card Dispensers in Parking Lots
• Parking Barrier Control
• Vehicle Access Control
• Traffic Control / Toll Systems
• Vehicle Counting Systems
• Motorised Gates and Doors
• Security Bollards / Rolling Shutters / Garage Doors
• Camera Trigger Systems

• Power LED (RED): Indicates "Power ON"
• CH1 Detecting LED:
  • Continuously On: Vehicle detection
  • Blinking slowly: Loop short circuit or insufficient twists
  • Blinking fast: Loop open circuit or excessive twists
• CH2 Detecting LED:
  • Continuously On: Vehicle detection
  • Blinking slowly: Loop short circuit or insufficient twists
  • Blinking fast: Loop open circuit or excessive twists

Sensitivity and frequency adjustment is achieved through 7-way and 10-way dip switch settings:

• Use ferromagnetic wires for induction coil (up to 500 meters total length)
• Coil cutting size: Rectangle 1.0-2.0m length × 0.8-1.2m width
• Avoid right angles at corners
• Keep product plug and socket in vertical direction during installation
