Note:when place this loop detector , please leave a massage for the voltage : 12v 24v 110v or 220v ,default is 220V， thank you !
Vehicle Loop Detector:
The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation location must choose to stay away from the heat source; it around other devices must maintain a distance of at least 10mm (must not installation close with boxes wall). A correct loop configuration and detector installation will ensure a successful inductive loop detection system. Loop of several important parameters include: loop figure, size, turns, install methods.
Operation and Indication
While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds, then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault is self-healing the detector will continue to operate. The green channel LED will also glow whenever a vehicle is detected passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the unit is powered.
