JUTAI Single Channel Vehicle Detector User Guide
Connections
The following photo illustrates the detailed connections for the JUTAI Single Channel Loop Detector LD100 and LD102. Typically, pins 1 and 2 are used to connect the power supply, and pins 8 and 9 are used to connect the loop coils. We generally recommend the JUTAI Loop Cable Mode JTHT-11. Pin 5 connects to GND. For more details, refer to the following connection guide.
Indicates And Switch
1. Power LED: The RED power LED indicates 'Power ON'.
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.
2. Switch 1 (Trimpot), Sensitivity Selection
The sensitivity of the loop can be adjusted using the trimpot labeled 'Sensitivity.' Users can select from 16 different settings, with '0' being the least sensitive and 'F' being the most sensitive.
3. Switch 2 (Dipswitch Settings)
(1) DIP 1 & DIP 2 Setting Special Functions
(2) DIP 3 & DIP 4 Setting Relay B Output
(3) DIP 5 Setting Automatic Reset
(4) DIP 6, DIP 7 & DIP 8 Setting Relay A Delay
(5) DIP 9 & DIP 10 Setting Frequency (40 K to 100 KHz). Used to avoid interference
In applications where two or more loop detectors and sensing loops are installed, set one detector to high frequency and another to low frequency to minimize cross-talk between systems. Ensure that sensing loops and detectors are positioned at least 2m apart.
4. Reset Button: Note: The LD-100 must be reset each time a setting is changed on the Dip switches.
Detector Position and Installation
1. Install the detector in a weatherproof housing.
2. Position the detector as close to the sensing loop as possible.
3. Avoid installing the detector near strong magnetic fields.
4. Keep high voltage wires away from the loop detectors.
5. Do not install the detector on vibrating objects.
6. For optimal performance, if your control box is installed within a 10-meter range of the loop, standard wiring will suffice for connection. However, for distances exceeding 10 meters, it is imperative to use a 2-core shielded cable. Please ensure that the distance between the control box and the loop does not exceed 30 meters to maintain operational integrity.
Loop Installation
To ensure seamless integration with the roadway surface, the loops are meticulously sealed using a 'quick-set' black epoxy compound or hot bitumen mastic. This method ensures durability and a blend-in finish with the road.
Trouble Shooting
The JUTAI LD-100/102 series vehicle detectors boast a substantial sensing range, adaptable from 15 µH to 2000 µH, making them capable of detecting a variety of vehicles including small cars, electric vehicles, motorcycles, conventional cars, trucks, and trailers. For optimal efficiency, setting the inductance around 300 µH is recommended. For instance, a coil size of 1 meter wide and 2 meters long should ideally have 8-10 turns to achieve a suitable inductive value for detecting all vehicle models. To expedite installation, you can first create a loop coil with these dimensions and measure the inductance value using a multimeter. Depending on the specific parking entry or exit channel size, you can adjust the coil size within this inductance range. Smaller diameter coils require more turns, while larger diameter coils require fewer turns. This flexible approach allows for efficient application across various entrance and exit sizes, thereby enhancing overall installation efficiency. For further details, please consult the project reference guide.
