110-240V Single Channel Boom Barrier Loop Sensor LD-100 Vehicle Detector

1. Introduction:
   • The Parking Barrier Gate Loop Detector is a sensor designed specifically for parking barrier gates, capable of efficiently identifying and detecting all types of vehicles, including oversized vehicles, trucks, motorcycles, and more, ensuring automatic gate opening and closing.
2. Features:
   • Single Channel Vehicle detector.
3. Advantages:
   • Wide Sensing Range and High Sensitivity: with a sensing range from 15 to 2000μH and high sensitivity, it accurately detects various vehicles, ensuring reliable detection performance.
   • Automatic Reset Function: the sensor automatically resets in case of a malfunction, eliminating the need for manual intervention and enhancing system stability and reliability.
   • Multiple Detection Level Selection: featuring 16 selectable levels ranging from 0.008% DL/L to 2.50% DL/L, it can be adjusted according to specific requirements, suitable for different application scenarios.
   • 40000V Lightning Protection: equipped with robust 40000V lightning protection, it effectively safeguards the sensor against damage from lightning strikes.
   • Wide Operating Environment Range: suitable for a wide range of operating environments, with a temperature range from -40°C to +70°C, ensuring stable operation even in harsh weather conditions.

Indicates and Switch:

• Power Led: RED power LED indicates "Power ON".
• Detecting Led:
  • Continuously On: Indicates vehicle detection.
  • Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
  • Blinking fast: Indicates loop is open circuit or too many twists after the loop.
• Switch 1 (Trimpot), Sensitivity Selection:
  • Sensitivity of the loop can be adjusted by the trimpot labeled "Sensitivity". User can select 16 different settings by turning the trimpot with 0 being the least sensitive and "F" being the most sensitive.
• Switch2 (Dipswitch Settings):
  • DIP1 & DIP2 Setting Special Functions:
    • DIP1 ON: Output has 2 seconds delay. (No relay output if the vehicle speed is over 8km/h).
    • DIP2 ON: Increase sensitivity to avoid unwilling relay off for leaving vehicle especially for trailer.
  • DIP3 & DIP 4 Setting Relay B Output:

    DIP MODE	Relay B Output	Loop Coils Status_L
    OFF OFF	When vehicle is moving out, output for relay B is 200m/s	Relay B Output Type_
    ON OFF	When the vehicle has left, output for relay B is 600m/s	Relay B will be present output. No Relay B Output Type_
    ON ON	Can be used to test the Loop. If the loop is faulty, Relay B will be on and it will switch off once the fault is fixed.

  • DIP 5 Setting Automatic Reset:

    DIP MODE	Present Mode
    ON	Vehicle can be permanently present (no auto - reset, unless vehicle has left or manual reset)
    OFF	Normal mode (automatic reset after 30 minutes present of vehicle, used to solve the mistake operation. If it is recommended)

  • DIP6 & DIP7 & DIP 8 Setting Relay ADelay:

    DIP MODE	Delay AOutput
    OFF OFF OFF	0 sec Output
    ON OFF OFF	2sec Output
    OFF ON OFF	5sec Output
    ON ON OFF	8 sec Output
    OFF OFF ON	10 sec Output
    ON OFF ON	15 sec Output
    OFF ON ON	20sec Output
    ON ON ON	30 sec Output

  • DIP9 & DIP 10 Setting Frequency (40 K to 100 KHz):

    DIP MODE	Frequency
    OFF OFF	High
    ON OFF	Medium - High
    OFF ON	Medium - Low
    ON ON	Low

    • In the application, where two or more loop detectors and sensing loops have been installed, set one detector to high frequency and the other set to low frequency to minimize the effects of cross - talk between the two systems (The sensing loops and detectors should be positioned at least 2m apart).
• Reset Button: Please note: The LD - 100 must be reset every time a setting change is made to the Dip switches.

Detector position and installation:

• Install the detector in a weatherproof housing.
• The detector should be as close to the sensing loop as possible.
• The detector should always be installed away from strong magnetic fields.
• Avoid running high voltage wires near the loop detectors.
• Do not install the detector on vibrating objects.
• When the control box is installed within 10 metres of the loop, normal wires can be used to connect the control box to the loop. More than 10 metres requires the use of a 2 core shielded cable. Do not exceed 30 metres distance between control box and loop.

Loop Installation:

• The loops are sealed using a "quick - set" black epoxy compound or hot bitumen mastic to blend with the roadway surface.
• Loop perimeter and Cylinder numbers:

  Loop perimeter	Cylinder numbers
  3 - 4M	6
  4 - 6M	5
  6 - 10M	4
  10 - 20M	3
  20M - UP	2

• TroubleShooting:
  • If the detector is not working: Press reset.
  • If red led indicator is not fully lit: Check for power supply.
  • If green led indicator:
    • Blinks slowly: It maybe because the loop is short circuit or the no: of turns is not enough.
    • Blinks faster: It maybe because the loop is open or the no: of turns is too many.
  • If no: of turns is not enough: Lower the frequency (if the frequency is still to high, you must add more turns).
  • If no: of turns is too many: Higher the frequency (if the frequency is still to low, you must remove some turns).
