Loop Sensor For Vehicle Access China Factory For Parking Access Control System

Loop Detector Wiring Diagram:

Loop Detector Wiring Diagram. The Loop Sensor For Vehicle  Access. Usually, the detection loop should be the rectangle. The two long sides are perpendicular to the direction of the movement of the metal object. The gap between them is recommended to be 0.8-1 meter. The length of the long side depends on the width of the road. Generally, both ends are narrow than the separation distance of the road for 0.3-1 meter. In order to make the detector work in the best condition, the inductance of the loop coil should be kept between 100uH-300uH, In the case of loop coil inductance unchanged. The cylinder numbers have an important relationship with the perimeter, the perimeter is smaller, cylinder more and more.:

Regular national standard Teflon cable, high-temperature wire, high-temperature resistance, a variety of colors. (Some manufacturers use ordinary tin-plated wire to pretend to sell high-temperature wire, which is a low-cost wire, but there is a big safety hazard in long-term use.) In China, there are many fakes, shoddy, so don’t use low prices. Purchasing goals, the key is good quality and fair price is the first choice.

loop detector troubleshooting:

If normal operation is not possible, please check:
A. Press the RESET button to RESET the detection host.
B. Observe the red LED light of POWER: if it is not on, check the external POWER supply and internal fuse.
C. If the LOOP/FAULT green LED flashes, it may be: the LOOP of the LOOP is short and the number of loops is insufficient (the flashing is slow); Open circuit, too many loops (quick flicker).
D. An insufficient number of wire loops (too high frequency): the frequency selection switch can be changed to LOW. If it is still too high, the number of wire loops must be increased.
E. Too many wire loops (too low frequency): the frequency selection switch can be changed to HI, if it is still too low, the number of wire loops must be reduced.
