Inductive Loop Vehicle Detector for Automatic Vehicle Parking System

Delivery Time:10 working days after received your payment
Certification:CE/ROHS/FCC/SGS
Application

Vehicle Loop detectors are used wherever vehicles have to be detected such as monitoring and safe guarding access ways or for counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parking lots.Model TLD-110 connects one inductive loop.

Operation and Indication
When the power is applied, the red Power LED will glow and the detector is tuning, the green Check LED blink about 3 seconds. The green LED will also glow whenever a 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 loops or loop detectors,
the frequency can be altered by DIP4 on 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.

【Attention】 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.

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.
