Indicators and Switches
Power LED (RED): Illuminates when "Power ON"
CH1 Detecting LED:
- Continuous: Vehicle detection
- Slow Blinking: Loop short circuit or insufficient twists
- Fast Blinking: Loop open circuit or excessive twists
CH2 Detecting LED:
- Continuous: Vehicle detection
- Slow Blinking: Loop short circuit or insufficient twists
- Fast Blinking: Loop open circuit or excessive twists
Sensitivity Selection
Sensitivity and frequency adjustments using 7-way and 10-way dip switch settings:
- Dip switches 6, 7, 8 control CH1 sensitivity (0.8 to 0.015)
- Dip switches 3, 4, 5 control CH2 sensitivity (0.8 to 0.015)
Reset Button Note: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
- 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
System Integration
JUTAI LD200/202 Double Channels Vehicle Loop Detector Series with direction recognition function for single-channel entry and exit applications.
Compatible Components
- JUTAI One door controller (Model: AC-11)
- JUTAI gate barrier (Model: BR-110)
- JUTAI long-range RFID reader (Model: PUHF-9)
- High-temperature resistance loop coils (Model: JTHT-11)
Operation Process
Entry Process
- Simultaneous Loop Coil Activation: Both loop coils are pressed when car enters
- UHF Reader Activation: LD-200/202 triggers UHF reader at entrance
- Card ID Reading: Reader transmits ID to controller via Wiegand output
- ID Verification and Gate Opening: Controller verifies ID and opens gate barrier
- Vehicle Entry: Barrier arm automatically lowers after vehicle passes
- Safety Assurance: LD-100/102 provides safety and anti-smashing functionality
Exit Process
- UHF Reader Activation: LD-200/202 triggers inside UHF reader
- ID Verification and Gate Opening: Controller verifies ID and opens exit barrier
- Vehicle Exit: Barrier arm lowers automatically after vehicle passes
- Safety Measures: LD-100/102 provides safety during exit process
Direction Recognition
Ensures double channels loop detector does not trigger signal again when car passes another UHF reader, maintaining accurate entry/exit records.
Independent Working Mode
The JUTAI LD-200/202 can function as two independent single-channel loop detectors for standard one-in and one-out parking lots:
- One loop coil triggers reader and reads card
- Other loop coil provides barrier anti-smashing function
- Cost-saving benefit by reducing hardware requirements
