1 Overview Congratulations for purchasing your Wireless Magnetic Sensor. This manual will support the installation of both in-pavement and surface mount models of the sensor, VSN240-F and VSN240-S respectively. The sensors use deviations in the earth’s magnetic field along three axes, to determine the presence or absence of a vehicle at the sensors location. Event information is then wirelessly transmitted back to an Access Point, AP240, which is responsible for analysis and further reporting.
2 Package Contents Each VSN240 comes with the items found in the list below. If any of the contents is missing, contact customer service at support@sensysnworks.com. • VSN240 Installation and Users manual. • The sensor itself (sealed and ready for installation). • An information sheet specifying the information below: o Senor ID (In hexadecimal format). o Operating Channel o Time Slot Assignment o Software Release Version o Board Rev Number o Battery Age o System Certification Checks.
3 Installation NOTE: Sensys Networks is exempt from all responsibility of damage and injury caused by the installation or improper installation of either of the VSN240-F or VSN240-S sensors. Sensys Networks can recommend a “best method” of installation based on lab testing and field experience. It is at the discretion of the customer to choose how the installation will proceed. The recommended installation of the flush mount sensors is very different from the recommended installation of the surface mount.
Required Equipment: i. VSN240-F Sensor ii. Gloves and safety glasses. iii. At least 200ml or 2/3 of a SmartStud Adhesive tube. iv. SmartStud applicator. v. The “Grinding” and “Double” Coring Bits. See Coring Bit Section below. vi. Chisel and hammer. vii. Coring Drill and frame. (Milwaukee 510067 or comparable). viii. Shop Vacuum or brush. ix. Heat gun or propane torch. * When installing in moist environments.
Figure 2 Coring Bits The 4” inch Double Cylinder Coring bit is recommend to be used in conjunction with the Grinding Coring bit. The Double Cylinder bit is used to drill the initial two inch hole, with the remaining asphalt chiseled away. Then the Grinding bit is used to make the bottom of the hole flat. Installation Procedure The SmartStud Adhesive and many other industrial epoxies and adhesives come in single use canisters.
assure proper adhesion. v. If moisture is noticed, use heat-gun and or propane torch to dry the inside or the cored hole. vi. Using Section 4, prepare SmartStud Adhesive for application. If another epoxy or adhesive is used, the preparation procedure should be completed. vii. Fill the hole ¼ full of the adhesive. viii. Determine Sensor orientation (See Sensor Location and Orientation section), and place sensor in the hole.
Sensor Location and Orientation • Sensors should be installed in the middle of the lane. • The arrow (⇐) sticker on the sensor should be parallel to the direction of traffic flow. Metal Brush It is imperative that the application surface is free of dirt, grime, and oil. Using a drill based metal brush has proved to be a very good solution for cleaning the pavement surface.
adhesive is used, the preparation procedure should be completed viii. Apply between 20%-25% of the 300ml tube, to the center of the cleaned location. ix. Determine Sensor orientation (See Sensor Location and Orientation section), and drop the sensor into the “puddle” of adhesive. Wiggle the sensor from side to side, and apply pressure until it is correctly oriented and rests flat on the cleaned surface.
4 Using the SmartStud Adhesive There are three major points or requirements that must be accounted for when using the SmartStud adhesive. Verify that the following criteria can be met before proceeding with the installation. • WORK QUICKLY: After the first application, do not let it sit static for more then 30 seconds before the next application. • NO MOISTURE: There must be absolutely no moisture on the applied surface.
This secures the mixing nozzle. Adhesive Applicator i. Fit Adhesive into applicator gun. ii. Keeping the gun upright, purge material until it runs black. Dispense a small amount of adhesive in the bag/box to verify proper mixing. iii. Start installation.
5 Configuration and Integration This section does not supplement the VDS240 Wireless Vehicle Detection System Users Guide in anyway. It should be used as a brief introduction the VDS240 detection system, and provide the simplest mean of integrating the sensor with an Access Point. Overview The only way to communicate, and therefore configure the sensor, is via an Access Point (AP240-E/S).
6 Support and Warranty Information Both VSN240-F and VSN240-S sensors come with a one year equipment replacement warranty.
