LOOP INSTALLATION PRECAUTION:
¡ The loop is installed under the road in order to detect the vehicle.
¡ The cable used has a 1.5 mm² section.
¡ No metallic mass must be located less than 1 metre away from the loop so as not to disturb the detection of the vehicle.
¡ The loop must be 25 metres for optimum efficiency.
¡ Prior to the fitting of the loop, make a 3mm wide and 40mm deep groove in the ground.
LOOP TAIL:
¡ The loop tail must be composed of an insulating sheathed braid made up of 20 braids/metre.
¡ The loop must be fitted more than 1 metre away from any metal mass.
CONNECTING CABLE:
¡ The connecting cable must be twisted at a rate of 20 braids/metre and must be shielded with a ground shielding connection on the detector side.
¡ The loop tail and the connecting cable must be connected to the detector contained in the power supply box.
¡ The insulation of the assembly must reach an order value of 1MΩ in relation to the ground.
¡ Adjusting the sensitivity of the loop detector:
¡ There are 3 levels of sensitivity. For the adjustment, refer to the constructor instructions (provided with the product).
¡ Cable section: 1.5 mm²
¡ The braid of the loops must be connected to the mass.
