Power LED (RED): Illuminates when "Power ON"
CH1 Detecting LED:

• Continuous: Vehicle detection
• Slow Blinking: Loop short circuit or insufficient twists
• Fast Blinking: Loop open circuit or excessive twists

CH2 Detecting LED:

• Continuous: Vehicle detection
• Slow Blinking: Loop short circuit or insufficient twists
• Fast Blinking: Loop open circuit or excessive twists

Sensitivity and frequency adjustments using 7-way and 10-way dip switch settings:

• Dip switches 6, 7, 8 control CH1 sensitivity (0.8 to 0.015)
• Dip switches 3, 4, 5 control CH2 sensitivity (0.8 to 0.015)

• Use ferromagnetic wires for induction coil (up to 500 meters total length)
• Coil cutting size: Rectangle 1.0-2.0m length * 0.8-1.2m width
• Avoid right angles at corners
• Keep product plug and socket in vertical direction during installation

JUTAI LD200/202 Double Channels Vehicle Loop Detector Series with direction recognition function for single-channel entry and exit applications.

• JUTAI One door controller (Model: AC-11)
• JUTAI gate barrier (Model: BR-110)
• JUTAI long-range RFID reader (Model: PUHF-9)
• High-temperature resistance loop coils (Model: JTHT-11)

Ensures double channels loop detector does not trigger signal again when car passes another UHF reader, maintaining accurate entry/exit records.

The JUTAI LD-200/202 can function as two independent single-channel loop detectors for standard one-in and one-out parking lots:

• One loop coil triggers reader and reads card
• Other loop coil provides barrier anti-smashing function
• Cost-saving benefit by reducing hardware requirements
