Double Loop Vehicle Detector Installation Loop Detector Vehicle

Installation Guide for Double Loop Vehicle Detector

Before proceeding with the installation of the dual-way loop vehicle detector, it's crucial to determine the optimal placement for the coil. Begin by marking the cutting pattern at the intended installation site, ensuring the loop detector coil is cut in a shape that avoids right angles to prevent damage to the wire insulation. Detailed installation requirements are provided with your purchase and should be consulted alongside the instruction manual.

For the installation, it is recommended to use a multi-core cord with a cross-sectional area larger than 1.0mm². The dimensions of the cutting coil typically range from 1.0m to 2.0m in length and 0.8m to 1.2m in width. The installation coil should span approximately 3-4 meters in length. The number of turns in the coil depends on the circumference:

• For a coil circumference of about 4-6 meters, use around 5 turns.
• For 6-10 meters, use approximately 4 turns.
• For 10-20 meters, opt for 3 turns.
• For coils exceeding 20 meters in circumference, use 2 turns.

Ensure there is sufficient leftover wire from the coil, approximately 15mm, which should be twisted and connected to the detector. The number of coil windings affects signal frequency: more windings result in a lower frequency and weaker signal reception, while fewer windings lead to a higher frequency and stronger signal. Arrange the coils logically to optimize performance.

During installation, avoid placing the coils near electric shutter doors or areas prone to signal interference to ensure optimal detector functionality.

By following these guidelines, you can effectively install and optimize the performance of your double loop vehicle detector.

If the display of the Two-way Loop Vehicle Detector Installation malfunctions after installation, follow these troubleshooting steps methodically:

1. RESET Button: Start by checking the RESET button, which resets the detection host.

2. POWER LED: Check the status of the POWER LED indicator. If it does not illuminate, inspect both the external power supply and the internal fuse.

3. CH1/CH2 Green LED:

   • If flashing, it suggests a possible short circuit in the coil circuit.
   • Slow flashing indicates insufficient coil turns.
   • Fast flashing indicates too few open coils.

4. Frequency Adjustment of our Double Loop Vehicle Detector:

   • High Frequency (Fast Flashing): Adjust the frequency selector switch to LOW. If the issue persists, increase the number of coil turns.
   • Low Frequency (Slow Flashing): Adjust the frequency selector switch to HI. If the issue continues, reduce the number of coil turns.

5. Long, Single Flash: Indicates a previous circuit failure.

By following these steps, you can systematically identify and rectify issues with the Double Loop Vehicle Detector, ensuring it operates correctly. If the problem persists after performing these checks, please consult the detailed troubleshooting section in the installation manual or contact technical support for further assistance.
