Connections and Indicators
Dual Channel Vehicle Loop Detector For Parking Access Vehicle Detector Parking System
Indicators and Switches:
  • Power LED (RED): Indicates "Power ON"
  • CH1 Detecting LED:
    • Continuously On: Indicates vehicle detection
    • Blinking slowly: Indicates a loop short circuit or insufficient twists after the loop
    • Blinking fast: Indicates a loop open circuit or excessive twists after the loop
  • CH2 Detecting LED:
    • Continuously On: Indicates vehicle detection
    • Blinking slowly: Indicates a loop short circuit or insufficient twists after the loop

Installation Precautions and Troubleshooting
  • Coil Cutting Size and Embedding Guidelines are as shown in the diagram on the right
  • It is recommended to use ferromagnetic wires for the induction coil, with a total length of up to 500 meters
  • The cutting size of the coil should be a rectangle with a length of 1.0 to 2.0 meters and a width of 0.8 to 1.2 meters, avoiding right angles at corners as much as possible
  • Recommended installation overview of basic typical coil turns

Working Principle
Entry Process Exit Process
  1. Both loop coils are pressed as a car enters
  2. LD-200/202 triggers the UHF reader at the entrance
  3. UHF reader sends the ID to the controller (AC-11)
  4. Controller outputs a relay signal to open the gate barrier
  5. Car enters and barrier arm lowers automatically
  6. LD-100/102 ensures safety and anti-smashing functionality during this process
  1. Car passes by an inside UHF reader as it exits
  2. LD-200/202 triggers the UHF reader, which reads the card ID
  3. Controller verifies ID's validity and opens gate barrier
  4. Car exits as barrier arm lowers automatically
  5. LD-100/102 provides safety and anti-smashing functionality
Direction Recognition and Applications
Direction Recognition: The Direction Recognition Function of LD-200/LD-202 ensures that the detector does not trigger the signal again when the car passes another UHF reader, recording only the entry or exit records in the system.
Application: JUTAI LD200/202 double channels vehicle loop detector series, equipped with direction recognition function, suitable for many single-channel entry and exit cases. Can connect to JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), combined with high-temperature resistance loop coils (Model: JTHT-11), ideal for single-channel entry/exit access control systems.
Functionality as Two Independent Single-channel Loop Detectors: LD-200/202 can function as two independent single-channel loop detectors, suitable for standard one-in and one-out parking lots. One loop coil triggers the reader and reads the card, while the other is dedicated to the barrier's anti-smashing function. This configuration reduces hardware costs associated with using separate detectors for each function, offering potential cost-saving benefits from an economic standpoint. Achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
