110V 50M Traffic Inductive Loop Vehicle Detector

    The vehicle detector is mainly used in vehicle (metal) detection. It¡¯s suitable for parking, Highway Toll Station and traffic signal control, etc. The detector is a single channel detector, which only can simultaneously monitor an inductance coil. It has two relay to output signals, so the user can choose different output signal to control the mechanical drive, the card device or vehicles counting.

Install Detector

The loop detectors must only be placed in dry rooms or control cabinets that are protected against all types of moisture and wetness. A distance of at least 10 mm from other devices must be maintained on each side. The ambient temperature must not exceed 65¡ã C. The installation of the induction loop is described in other operating instructions.

Operation and Indication

When the power is applied, the red Power LED will glow and the detector is tuning, the green Check LED blinkabout 3 seconds. The green LED will also glow whenevera vehicle is detected passing over the inductive loop. If a loop fault exists the green LED will come on and flash indicating a fault.

Frequency

¡¡

To eliminate interference of two neighbouring wire loopsor loop detectors, the frequency can be altered by DIP4on the main board in the box.

Sensitivity

The response sensitivity can be set using the threestage switch on the front. The setting ¡°L¡± corresponds to the lowest sensitivity. ¡°M¡± is the medium sensitivity and ¡°H¡± is the highest sensitivity.

After the sensitivity has been set, a reset and a calibration automatically takes place.

If the detector isn¡¯t working normally, you must check the loop and wiring at first, and then alter the frequency or the sensitivity.

Output Relay

The output of relay 2 can be programmed by means of DIP3 Switch.

If DIP3 is ¡°OFF¡± site, the output is presence output. When a vehicle is detected passing over the inductive loop, the relay 2 is energized( Pin3 and Pin4 is shorted) until the vehicle is detected leaving the loop. If DIP3 is ¡°ON¡± site, the output of redlay 2 is same as relay 1.

The output of relay 1 can be programmed by means of DIP1 and DIP2 Switch.

DIP1   DIP2                                Output mode of relay1

OFF   OFF  When a vehicle is detected leaving the loop, relay1 is energized 1 S after 300 mS.

ON    OFF  When a vehicle is detected passing the loop, relay1 is energized at once and disconnect after 300ms.

OFF   ON   When a vehicle is detected passing the loop after 300ms, relay1 is energized until the vehicle is detected leaving the loop.

ON    ON   When a vehicle is detected passing the loop, relay1 is energized until the vehicle is detected leaving the loop after 300 mS.

Reset

The detector automatically reset and tune to the inductive loop when the power is applied, whether on initial installation or after any break in power supply. Should it be necessary to retune the detector, as may be required after changing any of the switches or after moving the detector from one installation to another.
