usedd in parking system
high way traffice system to detect
count cars and realise te direction of cars.

Signal channel loop detector:<ul>
Main character: 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
With links diagram</ul>
Work indicator:<ul>
Detector will enter into the self-calibration condition with the green LED flash, red LED extinguish once on power, this procession will last for 1 second
The vehicle should not be on the loops within the self-calibration
The green LED will not flash, the red LED extinguish after self-calibration, when the vehicle past over the loop, the red LED on</ul>
DIP switch and wire jumper:<ul> DIP12 setting the sensitivity set the presence output time of relay 1 by DIP 3, set the relay 2 as presence/pulse output by DIP 4
The output time of presence signal set by DIP 5, DIP 6 set the frequency jumper wire connect to the open end, pin 16 connect to the no of relay
Jumper wire connect to the close end, pin 16 connect to the NC of relay 1</ul>
Work frequency:<ul> user can change the loop's work frequency which can avoid the cross talk by the adjacent loop or environment frequency
It offers two styles frequencies, set by DIP 6</ul>
Sensitivity adjustable:<ul> the DIP 1, DIP 2 on the front panel can adjust the sensitivity, if the vehicle has not any response when test it, the sensitivity should be improved</ul>
LED indicator: green/red
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
