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)

Yes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Product Description

LD-200 Double Channel Loop Sensor For Parking Barrier Access Vehicle Detector

Professional Dual Channel Vehicle Loop Detector

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

Key Features

Dual Channel Operation

Detects vehicles on two separate loops (CH1 and CH2) for comprehensive monitoring

Visual Indicators

Power LED (RED) indicates "Power ON", CH1 and CH2 Detection LEDs show vehicle detection and loop status

Adjustable Settings

Sensitivity and frequency adjustment via dip switches for customized operation

Multiple Operation Modes

Various modes for direction detection and normal operation with reset functionality

Technical Advantages

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

Operation Modes

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)

Connection Diagram

Indicator Functions

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

Switch Configuration

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

Reset Requirement: 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

Working Principle

Entry Process	Exit Process
Both loop coils detect car entry LD-200/202 triggers UHF reader at entrance UHF reader sends ID to controller (AC-11) Controller outputs relay signal to open gate barrier Car enters and barrier lowers automatically LD-100/102 ensures safety and anti-smashing functionality	Car passes inside UHF reader during exit LD-200/202 triggers UHF reader to read card ID Controller verifies ID validity and opens gate barrier Car exits as barrier arm lowers automatically LD-100/102 provides safety and anti-smashing functionality

Troubleshooting Guide

Symptoms	Solution
Detector not working	Press reset button
Red LED indicator not fully lit	Check power supply
Green LED blinking slowly	Loop short circuit or insufficient turns - lower frequency or add turns
Green LED blinking faster	Loop open circuit or excessive turns - higher frequency or remove turns
