Connections
Indicators and Switches
Power LED (RED): Illuminates to indicate "Power ON."
CH1 Detection LED:
Steady On: Indicates vehicle detection
Slow Blinking: Indicates a loop short circuit or insufficient twists after the loop
Fast Blinking: Indicates a loop open circuit or excessive twists after the loop
CH2 Detection LED:
Steady On: Indicates vehicle detection
Slow Blinking: Indicates a loop short circuit or insufficient twists after the loop
Fast Blinking: Indicates a loop open circuit or excessive twists after the loop
Sensitivity Selection
Sensitivity and frequency adjustment is facilitated through a 7-way dip switch and 10-way dip switch settings. Users can choose from 8 different sensitivity settings by configuring the dip switch positions according to the provided tables.
Dip switches 6, 7, and 8 govern CH1 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive)
Dip switches 3, 4, and 5 control CH2 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive)
Switch 1 (S1): Channel 1 Loop Function Selection
Special Sensitivity Increase For Both Trailer (Both Channels)
Special Functions Setting (Direction Detection Modes)
CH1 and CH2 Sensitivity Selection
Frequency Settings (20 K to 100 KHz)
Reset Button: Please note: The LD-200 must be reset every time a setting change is made to the Dip switches.
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
When installing, please keep the product plug and socket in the vertical direction
Application
The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for numerous single-channel entry and exit scenarios. When integrated with the JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), along with high-temperature resistance loop coils (Model: JTHT-11), it forms a seamless solution for single-channel entry/exit access control systems.
Working Principle
Entry Process:
When a car enters the community or parking lot, the two loop coils are pressed simultaneously
The JUTAI Double Channel Loop Detector (LD-200/202) triggers the UHF reader located at the entrance
The UHF reader reads the card ID and sends it to the controller (AC-11) via Wiegand output
The controller verifies the ID's validity and outputs a relay signal to open the gate barrier
The car enters the community or parking lot, and as it passes the barrier gate, the barrier arm lowers automatically
The JUTAI Single Channel Loop Detector (LD-100/102) ensures safety and anti-smashing functionality during this process
Exit Process:
When a car exits the community or parking lot, it passes by an inside UHF reader
The LD-200/LD-202 triggers the UHF reader, which reads the card and sends the ID to the controller
The controller verifies the ID's validity and outputs a relay signal to open the gate barrier for the car to exit
As the car passes through the barrier gate, the barrier arm lowers automatically
The LD-100/102 provides safety and anti-smashing functionality during this process
Direction Recognition:
The Direction Recognition Function of LD-200/LD-202 ensures that the double channels loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system
The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.
In this setup, one loop coil is used to trigger the reader and read the card, while the other loop coil is dedicated to the barrier's anti-smashing function. By utilizing the LD-200/202 as two independent loop detectors, there is a potential cost-saving benefit from an economic standpoint. This setup reduces some of the hardware costs associated with using separate detectors for each function.
This functionality is achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
