220V Smart Automatic Barrier Opener Vehicle Loop Detector System

When the detector is tuning, the green channel LED and the red power LED will illuminate. It stays for about 2 seconds and then the green LED goes out. If there is a loop failure, the channel LED will illuminate and flash to indicate a fault. If the fault is self-healing, the detector will continue to run. The green channel LED will also illuminate as soon as the vehicle is detected to pass through the inductive loop. The red power LED on the top of the unit will remain lit, indicating that the unit is powered.Features:The pulse relay can be configured to activate the detection of the vehicle or when the vehicle leaves the loop.This characteristic determines the non-detection level at maximum sensitivity to avoid detecting vehicles such as large trucks.Sensitivity can be changed using four sensitivity settings on the switch.Four frequency configurations can be used to avoid signals from interfering with adjacent loops.This relay is typically used to prevent false detection of small or fast objects.Specifications:Condition: Brand NewMaterial: ABSColor: BlackReaction time: 10 msPower consumption: 4.5 VAOutput relay: 240 V/ 5 AOperating temperature: -20°C to +65°CStorage temperature: -40°C to +85°CFrequency range: 20 kHz to 170 kHzSensitivity: adjustable in 4 incrementsSignal hold time: unlimited /limit cycle for 10 minutes permanentlyLoop inductance: The total loop plus connection line is 50μH to 1000μH (ideally 100μH to 300μH).Loop connection wiring: Maximum length 20 meters, twisted at least 20 times per meter.Package List:1* Barrier Opener1* Connection Terminal1* Instruction ManualNote:1.The detector must be installed in a convenient weatherproof position as close as possible to the loop.2.The installation location must be chosen away from the heat source.3.Other equipment around it must be at least 10 mm away (not to be tightly mounted to the wall).4.Proper loop configuration and detector installation will ensure a successful inductive loop detection system.5.Several important parameters of the loop include: cycle diagram, size, turn, and installation method..6. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
