12V 24V Car Parking Barrier Loop Detector for Detection of Vehicles with 50m 075mm Inductive Loop Coil Wire For the loop detector, Dual12V / 24V available Package include: 1 x Loop Vehicle Detector 1 x 50m Inductive Loop Wire Data for loop Wire: 1. each pc is 50 meters; customised length is avaible(please contact the seller if needed) 2. Anti-corrosion, anti-combustion, perfect insulation, Acid-Alkaline resistant Datas for loop detector: Power supply: AC/DC12~24V Output relay: 120V/3A AC; Work temperature: -20~70 Loop inductance range: 50~800uH100~300uH Work frequency: 20~130KHzSensitivity: four class adjustable Dimension: 7922.590mmLWH Fueature: When the DIP switch is on position or changing the presence output time;, Self-detection would be done; ABS align to the pillar which can combine with each other compactly; Presence output time can be adjustable; Work mode can be set by the DIP switch; Pulse output or permanent output can be adjustable; 2. Work indicator Detector will enter into the self-calibration condition with the green LED flash, red LED extinguish once on power, this procession will last 1 second. .the vehicle should not on the loops within the self-calibration. The green LED will not flash, he red LED extinguish after self-calibration. When the vehicle past over the loop ,the red LED on. 3. DIP SWITCH and wire jumper DIP12 setting the sensitivityset the presence output time of relay 1 by DIP3set the relay2 as presence/pulse output by DIP4; the output time of presence signal set by DIP5DIP6set the frequencyjumper wire connect to the open end,PIN16 connect to the NO of relay 1. Jumper wire connect to the close end, PIN16 connect to the NC of relay 1. 7. Relay work way 15,16 pins are signal output., when the jumper wire in open ,and the vehicle entre into loops ,the two pins pull in and conduction. The two pins disconnect when the vehicle left the loop. When the jumper wire connect to close end, the 15,16 pins not pull in when the vehicle entre into the loops .the two pins pull in when the vehicle left the loops.(presence time can be set by DIP3) Pin 25,28 can be regard as signal output or pulse output. Dialing DIP4 to OFF position, when the vehicle left the loops, disconnect after pulling in 1s (pulse output) ;Dialing DIP4 to ON ,the two pins pull in after the vehicle pass the loops (presence output) 8. Presence time setting Set the presence time by DIP3 switch. Dialing the DIP3 to OFF, Holding time 5 minutes (when the stay time of the vehicle is more than 5 minutes, the detector will be reset and come back to the carless condition).when dialing the DIP3 to ON, the presence time is unlimited(when the vehicle stay on the loops, holding time unlimited).set the presence signal by DIP5. Dialing the DIP5 to OFF, once the vehicle entre into the loops, signal be output at once .Dialing DIP5 to ON, signal would be output after two seconds _x000D_
