  • Blinking fast: Indicates loop is open circuit or too many twists after the loop
• CH2 Detecting Led:
  • Continuously On: Indicates vehicle detection
  • Blinking slowly: Indicates loop is short circuit or insufficient twists after the loop
  • Blinking fast: Indicates loop is open circuit or too many twists after the loop

Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting. Users can select 8 different settings by changing the dipswitch to different modes.

Dip switch 6, 7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.

Dip switch 3, 4 and 5 for CH2 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.

Switch 1 (S1): Channel 1 Loop Function Selection (10 way dip switch)

(Switch 1) DIP 1 & DIP 2: Special Sensitivity Increase For Both Trailer (Both Channels)

(Switch 1=S1) D3, D4, D5 and (Switch 2=S2) D1, D2: Setting Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode, two loop detection are separated)

(Switch 1=S1) D6 & D7 & D8 and (Switch 2=S2) D3 & D4 & D5: Setting CH1 and CH2 Sensitivity Selection (Eight Levels Choices)

(Switch 1=S1) D9 & D10 and (Switch2=S2) D6, D7: Setting Frequency (20 K to 100 KHz)

The loops should be sealed using a "quick-set" black epoxy compound or hot bitumen mastic to seamlessly blend with the roadway surface.

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

The JUTAI LD-200/202 Double Channel Vehicle Loop Detector series, equipped with direction recognition functionality, 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), combined with high-temperature-resistant loop coils (Model: JTHT-11), it forms an efficient solution for single-channel entry/exit access control systems.

1. Upon a vehicle's entry into the community or parking lot, simultaneous activation of the two loop coils occurs
2. The JUTAI Double Channel Loop Detector (LD-202) triggers the UHF reader positioned at the entrance
3. Upon reading the card ID, the UHF reader transmits the ID to the controller (AC-11) via Wiegand output
4. The controller verifies the ID's validity and outputs a relay signal to open the gate barrier
5. Once the vehicle enters the community or parking lot, the barrier arm automatically lowers
6. The safety and anti-smashing function is facilitated by the JUTAI Single Channel Loop Detector (LD-100/102)

1. As the vehicle exits the community or parking lot and passes the internal UHF reader, the LD-202 triggers the UHF reader
2. The reader reads the card and sends the ID to the controller
3. Upon validation of the ID, the controller emits a relay signal to open the gate barrier
4. After the vehicle exits the community or parking lot, the barrier arm lowers automatically
5. The safety and anti-smashing function is facilitated by the JUTAI Single Channel Loop Detector (LD-100/102)

In both scenarios, the LD-202's Direction Recognition Function ensures accurate and efficient operation.

JUTAI LD-202 Double Channel Loop Detector can function as two independent single-channel loop detectors, offering versatility and cost-efficiency. This configuration is ideal for standard one-in and one-out parking lots, where a single barrier and long-range reader are installed at both the entrance and exit. One loop coil is dedicated to triggering the reader and reading the card, while the other loop coil is utilized for the barrier's anti-smashing function. Enabling the Independent Working Mode function of the LD-202 streamlines operations and reduces hardware costs, making it a practical choice for various applications.
