loop detector

loop detector
Product Detailed
high quality best price CE and ROHS report

signal channel loop detector 

u    TLD-M1H user manual

1Main 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

1) Links diagram

 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.

4. Work frequency

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 frequency, set by DIP6  

5. Sensitivity adjustable

The DIP1,DIP2 on the front panel can adjust the sensitivity. If the vehicle has not any response when test it, the sensitivity should be improved.    

6.LED indicator

green      red

off          OFF---------no power

flash        flash----------self-detection

on          off----------vehicle entre into the work condition

on          on----------vehicle entre into the work condition

off          on-----------can not detect the loops

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
