Professional 110-240VAC Double Channel Vehicle Loop Detector For Activating Card Dispensers in Parking Lots

JUTAI develops a multi-functional underground loop detection, which can use as dual channel loop detectors, users can use one unit dual channel loop detector with two-channel loop coils for activating entrance card dispensers, and another coil use for barrier gate safety closing loop. Jutai offers the best vehicle loop detector for any driveway gate control system or car parking management system.

Dual Channel Loop Detector For Activating Card Dispensers Features

1. Compact Size: the compact and well-engineered housing, Combines all of the industry requirements regarding Features and functionality and allows this detector to be Incorporated into any or existing traffic detection system.
2. Diagnostic Capabilities: Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.
3. Selectable Presence Time: The output of the presence relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop.
4. Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.
5. Direction Detection : (If the vehicle moves from CH1 to CH2, then CH1 relay output; if the vehicle moves from CH2 to CH1, then CH2 relay output).
6. Sensitivity Selection: Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.

  • 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.
  • Blinking fast: Indicates a loop open circuit or excessive twists after the loop.

Sensitivity Selection:

• Sensitivity and frequency adjustment is achieved through a 7-way dip switch and 10-way dip switch settings.
• Users can select from 8 different settings by adjusting the dip switch positions according to the tables provided. Dip switches 6, 7, and 8 control CH1 sensitivity, with 0.8 being the least sensitive and 0.015 being the most sensitive.
• Dip switches 3, 4, and 5 control CH2 sensitivity, with 0.8 being the least sensitive and 0.015 being the most sensitive.

* 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:

1. Coil Cutting Size and Embedding Guidelines are as shown in the diagram on the right.
2. It is recommended to use ferromagnetic wires for the induction coil, with a total length of up to 500 meters.
3. 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.
4. Recommended installation overview of basic typical coil turns:

When installation, please keep the product plug and socket in the vertical direction

Working Principle

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.
