Installation & Configuration
Double Channel Loop Detector connections diagram
Indicator Functions
  • Power LED (RED): Indicates "Power ON" status
  • CH1 Detecting LED:
    • Continuously On: Vehicle detection active
    • Blinking slowly: Loop short circuit or insufficient twists
    • Blinking fast: Loop open circuit or excessive twists
  • CH2 Detecting LED:
    • Continuously On: Vehicle detection active
    • Blinking slowly: Loop short circuit or insufficient twists
    • Blinking fast: Loop open circuit or excessive twists
Sensitivity Selection

Sensitivity and frequency adjustment is achieved through 7-way and 10-way dip switch settings with 8 different sensitivity levels available.

Loop detector switch configuration Special sensitivity increase settings Direction detection mode settings Sensitivity selection settings Frequency selection settings
Reset Requirement: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
  • Coil cutting size: Rectangle 1.0-2.0m length × 0.8-1.2m width
  • Avoid right angles at corners during installation
  • Use ferromagnetic wires with total length up to 500 meters
  • Keep product plug and socket in vertical direction during installation
Coil installation overview and typical turns Proper installation orientation
Working Principle
Entry Process Exit Process
  1. Both loop coils detect vehicle entry
  2. LD-200/202 triggers UHF reader at entrance
  3. UHF reader sends ID to controller (AC-11)
  4. Controller outputs relay signal to open gate barrier
  5. Vehicle enters and barrier lowers automatically
  6. LD-100/102 ensures safety and anti-smashing functionality
  1. Vehicle passes inside UHF reader during exit
  2. LD-200/202 triggers UHF reader to read card ID
  3. Controller verifies ID validity and opens gate barrier
  4. Vehicle exits and barrier lowers automatically
  5. LD-100/102 provides safety and anti-smashing functionality
Direction Recognition

The Direction Recognition Function prevents duplicate triggering when vehicles pass additional UHF readers, ensuring accurate entry/exit record keeping.

System Integration

Compatible with JUTAI door controller (AC-11), gate barrier (BR-110), long-range RFID reader (PUHF-9), and high-temperature resistance loop coils (JTHT-11) for comprehensive access control solutions.

Independent Operation Mode

LD-200/202 can function as two independent single-channel loop detectors, ideal for standard one-in/one-out parking lots while reducing hardware costs.

Troubleshooting Guide
Symptoms Solution
Detector not working Press reset button
Red LED indicator not fully lit Check power supply connection
Green LED blinking slowly Possible loop short circuit or insufficient turns
Green LED blinking faster Possible loop open circuit or excessive turns
Insufficient number of turns Lower frequency (add more turns if frequency still too high)
Excessive number of turns Higher frequency (remove some turns if frequency still too low)
