    Hi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so)

Product Description
Dual Loop Vehicle Detector with 6 Working Modes
Professional parking barrier gate traffic and access control solution
Dual Loop Vehicle Detector Product Overview
Product Concept
This detector is designed around configuration flexibility. Two loop channels are combined with six selectable working modes so the same hardware can be used for different parking-barrier, access-control and traffic-management strategies. The installer chooses the required behavior with DIP switches rather than replacing the detector when the lane logic changes.
CH1 and CH2 can work together as a direction-sensing pair or separately as independent presence channels. Other modes provide pulse behavior associated with vehicle arrival or departure. This multi-mode structure is useful for integrators managing projects with varied entrance, exit and passage-control requirements.
Overview of the Six Modes
Mode 1: Direction-related pulse logic based on the CH1/CH2 sequence
Mode 2: Direction-related presence logic with a different relay timing pattern
Mode 3: Alternative directional presence behavior for another sequence requirement
Mode 4: CH1 and CH2 operate as separate presence outputs
Mode 5: Pulse output when a vehicle enters CH1 or CH2
Mode 6: Pulse output after a vehicle leaves CH1 or CH2
Sensitivity and Frequency Setup
Both detection channels have eight sensitivity settings from 0.015% to 0.8%. Frequency is selectable in four steps—High, Medium-High, Medium-Low and Low—within approximately 20-100kHz. This gives the installer two independent tools for optimizing detection and controlling cross-talk in multi-loop environments.
Vehicle Presence Management
The detector can be configured for permanent presence, where a vehicle remains detected until it leaves the loop or the detector is manually reset. In normal mode, automatic reset takes place after approximately 10 minutes of continuous presence. A special sensitivity increase function is also provided for trailer applications.
Key Benefits
  • One product covers multiple lane-control behaviors
  • Two loop inputs reduce the need for separate single-channel modules
  • Direction logic supports entrance and exit applications
  • Presence and pulse outputs support different controller inputs
  • Sensitivity and frequency can be adjusted during commissioning
  • LED status helps simplify fault finding

Applications
  • Parking barrier gates
  • Vehicle access-control lanes
  • Entrance and exit sequencing
  • Commercial parking management
  • Industrial vehicle gates
  • Traffic-control detection points
Installation Considerations
The loop perimeter determines the recommended number of turns. For example, the manual specifies six turns for a 3-4m loop perimeter and two turns for loops above 20m. For dual-loop directional layouts, the manual shows CH1 and CH2 as separate road loops positioned sequentially along the lane.

Indicators and Switches
  • Power LED (RED): Illuminates to indicate "Power ON"
  • CH1 Detection LED:
    • Steady On: Vehicle detection
    • Slow Blinking: Loop short circuit or insufficient twists
    • Fast Blinking: Loop open circuit or excessive twists
  • CH2 Detection LED:
    • Steady On: Vehicle detection
    • Slow Blinking: Loop short circuit or insufficient twists
    • Fast Blinking: Loop open circuit or excessive twists
Sensitivity Selection
Sensitivity and frequency adjustment is facilitated through 7-way and 10-way dip switch settings:
  • 8 different sensitivity settings available via dip switch configuration
  • Dip switches 6, 7, and 8 govern CH1 sensitivity (0.8 to 0.015)
  • Dip switches 3, 4, and 5 control CH2 sensitivity (0.8 to 0.015)

Switch Configuration
Switch 1 (S1) - Channel 1 Loop Function Selection:
  • DIP 1 & DIP 2: Special Sensitivity Increase For Both Trailer (Both Channels)
  • D3, D4, D5 and Switch 2 D1, D2: Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode)
  • D6 & D7 & D8 and Switch 2 D3 & D4 & D5: CH1 and CH2 Sensitivity Selection (Eight Levels)
  • D9 & D10 and Switch2 D6, D7: Frequency Selection (20 K to 100 KHz)

Reset Button Note: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
  • Coil cutting size should be rectangle: length 1.0 to 2.0 meters, width 0.8 to 1.2 meters
  • Avoid right angles at corners as much as possible
  • Use ferromagnetic wires for induction coil, total length up to 500 meters
  • Keep product plug and socket in vertical direction during installation

System Integration
The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for single-channel entry and exit scenarios when integrated with:
  • 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)
System Integration Diagram
Working Principle
Entry Process
  1. Car enters community/parking lot, pressing two loop coils simultaneously
  2. LD-200/202 triggers UHF reader at entrance
  3. UHF reader reads card ID and sends to controller via Wiegand output
  4. Controller verifies ID validity and outputs relay signal to open gate barrier
  5. Car enters, barrier arm lowers automatically
  6. LD-100/102 provides safety and anti-smashing functionality
Exit Process
  1. Car exits community/parking lot, passing inside UHF reader
  2. LD-200/LD-202 triggers UHF reader to read card and send ID to controller
  3. Controller verifies ID validity and outputs relay signal to open gate barrier
  4. Car exits, barrier arm lowers automatically
  5. LD-100/102 provides safety and anti-smashing functionality
Direction Recognition
The Direction Recognition Function ensures the double channels loop detector does not trigger the signal again when the car passes another UHF reader, recording only entry or exit records in the system.
Working Principle Diagram
Independent Operation Mode
The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors, suitable for standard one-in and one-out parking lots.
This configuration provides cost-saving benefits by reducing hardware costs associated with using separate detectors for each function.
