Connections

Indicates And Switch
Power Led: The RED power LED proudly displays "Power ON", ensuring that your device is effectively operational and ready to perform.
CH1 Detecting Led: When continuously illuminated, it reliably signals the presence of a vehicle.
Blinking slowly: This slow blink is an alert that the loop is in a short circuit or the number of twists after the loop is insufficient.
Blinking fast: A fast blink indicates an open circuit or an excessive number of twists after the loop, necessitating attention.
CH2 Detecting Led: When continuously lit, it indicates seamless vehicle detection.
Blinking slowly: A slow blink signifies a short circuit in the loop or an inadequate number of twists post-loop.
Blinking fast: This quick flash serves as an indicator of an open circuit or too many twists post-loop.
Sensitivity Selection
Adjust the sensitivity and frequency of the loop with precision using the 7-way dip switch and 10-way dip switch settings for optimal performance.
Choose from 8 distinct settings by altering the dipswitch modes as outlined in the tables below. Dip switches 6, 7, and 8 offer CH1 sensitivity selection, ranging from a low of 0.8 to an intense 0.015.
Dip switches 3, 4, and 5 are dedicated to CH2 sensitivity selection, giving options from a subtle 0.8 to a heightened 0.015 for precise operation.


3. Switch 1=S1: Channel 1 Loop Function Selection (10-way dip switch)
(1)(Switch 1) DIP 1 & DIP 2: Special Sensitivity Increase for Both Trailer (Both Channels).

(2)(Switch 1=S1) D3, D4, D5 and (Switch 2=S2) D1, D2: Configuring special functions-Mode 1, 2, 3 for direction detection; Mode 4, 5, 6 for normal mode with separate dual loop detection.

(3)(Switch 1=S1) D6 & D7 & D8 and (Switch 2=S2) D3 & D4 & D5: Customize CH1 and CH2 Sensitivity with eight distinct level choices.

(4)(Switch 1=S1) D9 & D10 and (Switch 2=S2) D6, D7: Set Frequency ranging from 20 KHz to 100 KHz for tailored applications.

* Reset Button: It's crucial to reset the LD-200 after every Dip switch setting adjustment to ensure optimal functionality.

Loop Installation
The loops are expertly sealed using either a "quick-set" black epoxy compound or hot bitumen mastic, seamlessly blending with the roadway surface for a professional finish.

During installation, ensure the product's plug and socket maintain a vertical orientation for optimal functionality.

Application
The JUTAI LD200/202 Double Channel Vehicle Loop Detector Series, equipped with direction recognition, is ideal for a multitude of single-channel entry and exit scenarios.
This detector seamlessly integrates with the JUTAI One Door Controller (Model: AC-11), JUTAI Gate Barrier (Model: BR-110), and JUTAI Long Range RFID Reader (Model: PUHF-9). Together with the high temperature resistant loop coils (Model: JTHT-11), it forms a perfect solution for single-channel entry/exit access control systems.

The Working Principle As Follows
When a vehicle approaches the entry point of a community or parking lot, it simultaneously activates two loop coils. At this pivotal juncture, the JUTAI Double Channel Loop Detector (LD-200/202) steps in to activate the UHF reader stationed at the entrance. Upon successful reading of the card ID by the UHF reader, the information is seamlessly transmitted to the controller (AC-11) through a Wiegand output. The controller, affirming the validity of the ID, dispatches a relay signal to open the gate barrier, allowing the vehicle to proceed into the community or parking area. As the vehicle clears the barrier, the arm automatically descends. This is ingeniously orchestrated with the JUTAI Single Channel Loop (LD100/102) to ensure safety and prevent incidents of barrier impact. Notably, when the vehicle advances past another UHF reader linked to the AC-11, this reader will remain untriggered by the loop detector and will not transmit data to the controller, resulting in software maintaining only ENTRY records. This is attributed to the active Direction Recognition Function of the LD200/LD202, ensuring precision and efficiency.

Conversely, during the vehicle's exit from the community or parking lot, as it approaches the internal UHF reader, the LD200/LD202 is activated, prompting the reader to capture the card ID and transmit it to the controller. The controller, upon validating the ID, sends a relay signal to lift the gate barrier, permitting the vehicle's departure. As the vehicle traverses the barrier, the arm automatically lowers. This process is synchronized with the JUTAI Single Channel Loop (LD100/102) to uphold safety and prevent barrier damage. However, as the vehicle passes another UHF reader at the exit, the Double Channel Loop Detector refrains from triggering again, ensuring the system records only EXIT data. The Direction Recognition Function of the LD200/LD202 is pivotal here, maintaining efficient traffic management and record accuracy.

The JUTAI LD-200/202 Double Channel Loop Detector is adept at functioning as two independent single-channel loop detectors, ideal for standard one-in, one-out parking lot configurations. This setup features a barrier and a long-range reader at both the entrance and exit points. One loop coil is designated to trigger the reader and capture the card data, while the other is dedicated to the barrier's anti-smashing functionality. When employed as two separate loop detectors, the LD-200/202 presents a cost-effective solution by minimizing hardware expenses. This is achieved through the activation of the Independent Working Mode function of the LD200/202, highlighting its versatility and economic efficiency.
