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.
DIP SWITCH and Wire Jumper
DIP1, 2 setting the sensitivity;set the presence output time of relay 1 by DIP3;set the relay2 as presence/pulse output by DIP4; the output time of presence signal set by DIP5;DIP6set the frequency; jumper 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
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
