The LD-200 loop detector is an intelligent, extremely flexible and very affordable product.
The LD-200 is designed to accommodate numerous applications, can be adjusted intelligently to any environments and virtually eliminating false detection.
On the front panel, the four selectable loop frequencies (20~80 KHz) can completely eliminate any crosstalk.
If intermittence happen or failed loops get self-healed, the detector will resume to normal operation without manually reset the detector.

Power Led: RED power LED indicates “Power ON”  
       CH1 Detecting Led:Continuously On: Indicates vehicle detection.
      Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop. 
      CH2 Detecting Led:Continuously On: Indicates vehicle detection.
      Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.

Blinking fast: Indicates loop is open circuit or too many twists after the loop.
