2. Gate Automation: Integrated into gate control systems for automatic opening and closing of gates in residential, commercial, and industrial settings.

3. Parking Facilities: Installed in parking lots and garages to manage vehicle entry and exit, count vehicles, and enforce parking regulations.

4. Access Control: Employed in access control systems to authorize vehicle entry at secured locations such as gated communities, industrial facilities, and military bases.

5. Traffic Light Control: Used to trigger traffic light changes based on vehicle presence and direction, optimizing traffic flow and reducing congestion.

6. Vehicle Counting: Utilized for vehicle counting applications in traffic studies, parking occupancy monitoring, and retail traffic analysis.

Connections

Indicates and Switch:

• Power LED (RED): Indicates "Power ON."
• CH1 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.
• 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.

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 Setting Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode, two loop detection are separated)

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

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

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

Application

JUTAI LD200/202 double channels vehicle loop detector series, it with direction recognition function, and which is suitable for many single-channel entry and exit cases.
JUTAI LD200/202 double channels loop detector 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), Which can be perfectly applied to single-channel entry/exit access control system.

JUTAI LD-200/202 Double channels loop detector also can be used as two independent single channel loop detectors. This is suitable for a standard one-in and one-out parking lot, There is one barrier and one long range reader at the entrance, exit same also; one loop coils is used to trigger reader and read card, and the other loops coils is used for the barrier anti-smashing function, when the LD-200/202 as two independent loop detector application, from an economic point of view, which can reduce part of the hardware cost; (Enable the Independent working mode function of LD200/202).
