Electromagnetic, Loop, detector, for barrier (loop, lasso)

The electromagnetic Loop detector for barriers (loop, lasso) serves to detect vehicles through an inductive circuit. It is used in various traffic control and monitoring systems, providing reliable detection of passing cars.

• Application in parking barriers for vehicle detection
• Used in systems for collecting information about parking spaces
• Suitable for electronic traffic light systems
• Applied in traffic monitoring systems

• Power supply voltage AC: 12V
• Power supply voltage DC: 12V
• Sensitivity: adjustable in 3 steps (high, medium, and low)
• Operating temperature: from -40 °C to +85 °C
• Reaction time: 100 ms
• Wired connection: maximum length 200 meters, twisted at least 20 times per meter
• Net weight: 300 g

The detector should be installed in a convenient and weather-protected location, as close as possible to the inductive loop. The location should be away from heat sources, maintaining a distance of at least 10 mm around other devices. Proper configuration of the loop and installation ensures successful operation of the detection system.

During setup, the green and red power LEDs light up. After about 2 seconds, the green LED turns off. If there is a fault in the loop, the green LED blinks, indicating a malfunction. If the fault is cleared, the detector continues to function. The green LED lights up when a vehicle is detected, while the red remains on, indicating that the device is powered.

Output relay 2 is pulse. With DIP7 in the "OFF" position, when a vehicle is detected, the relay is powered (Pin3 and Pin4 are shorted) and turns off after 500 ms. With DIP7 in the "ON" position, the relay is powered when the vehicle exits the loop and turns off after 500 ms.

Relay 1 serves as a presence output. It is powered (Pin5 and Pin6 are shorted) while the vehicle is in the inductive loop.

The presence time can be set to constant or limited. In constant presence mode, the detector compensates for all changes in the environment while the vehicle is in the loop. The setting is done with the DIP8 switch: OFF for limited presence (10 minutes) and ON for constant presence.

The detector automatically adjusts to the inductive loop when power is supplied, both during initial installation and after a power interruption. If a readjustment is needed, for example, after changing switches or moving the detector, pressing the RESET button starts an automatic adjustment cycle.
