FCC and ISED Compliance Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Devel- opment Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesiredoperation of the device. Cet appareil contient des émetteurs / récepteurs exemptés de licence conformes à l'innovation, RSS(s) exemptés de licence de Sciences et Développement économique Canada. Le fonctionnement est soumis à la suivant deux conditions: (1) l’appareil ne doit pas produire de brouillage; (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement. FCC and ISED RF Exposure Statements This equipment complies with FCC RF exposure safety guidelines for mobile devices and Canada RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & the user’s body when operating the device. L’appareillage répond aux limites de la norme RSS-102 sur l’exposition aux radiations établies pour un environnement non-contrôlé. Il devrait être installé et fonctionner à une distance minimale de 20 cm entre l’antenne et votre corps. Disclaimer The advertised detection accuracy of the Wavetronix SmartSensor sensors is based on both external and internal testing, as outlined in each product’s specification document. Although our sensors are very accurate by industry standards, like all other sensor manufacturers we cannot guarantee perfection or assure that no errors will ever occur in any particular applications of our technology. Therefore, beyond the express Limited Warranty that accompanies each sensor sold by the company, we offer no additional representations, warranties, guarantees or remedies to our customers. It is recom- mended that purchasers and integrators evaluate the accuracy of each sensor to determine the acceptable margin of error for each application within their particular system(s). 1 CHOOSING A MOUNTING LOCATION 5 Mounting location, height, and offset 5 Choosing where to mount 7 Choosing a mounting height and offset 8 Occlusion and multipathing 10 Fixing occlusion problems 10 Fixing multipath problems 2 INSTALLING THE XP20 11 Mounting the sensor 12 Aligning the sensor to the roadway 13 Assembling the cable 15 Applying silicon dielectric compound 16 Connecting the cable CONTENTS Chapter 1: Choosing a mounting location • 5 1 Choosing a mounting location Mounting location, height, and offset Choosing where to mount Figure 1. The XP20 radar footprint ˿ For best performance, make sure the lanes being detected are all parallel to each other; avoid on- and off-ramps/turn lanes that angle away from the road. 6 • Expanse XP20 User Guide ˿ Make sure all monitored lanes are within 6 to 250 ft. (1.8 to 76.2 m) of the sensor. Up to 22 lanes can be detected. ˿ If you’re putting a sensor on a road with stoplights or stop signs, position the sensor toward middle of the block, to reduce the likelihood of having stopped vehicles in the XP20 radar footprint. Figure 2. Midblock installation ˿ Keep cable lengths in mind when you pick mounting locations; when you use a Wavetronix or Wavetronix-recommended cable, the cable run between the XP20 and the cabinet can be as long as 2000 ft. (609.6 m). ˿ Consider timing: after a vehicle passes in front of the sensor, there’s a slight delay before the data for that vehicle is sent from the sensor. ˿ In a time-sensitive application, like supplying a variable mes- sage sign with per vehicle warning messages, make sure the sensor is far enough upstream from the sign that the system has time to collect the data, process it, and send it to the sign by the time the vehicles reach the problem area. ˿ See if you can take advantage of any existing infrastructure in the area. The sensor can be mounted on existing poles (with the exceptio…
