3. fast responding and accurate system designed for measurement of wind speed and wind direction The sensor is based on three ultrasonic transducers arranged in a triangle for measuring of wind speed and wind direction By measuring the time it takes for a set of ultrasound bursts to travel from each transducer to the other two the wind speed and direction can be calculated The WSS REC has a built in heater which will automatically engage when risk of icing occurs during low temperatures DEIF A S Page 3 of 14 55 User s Manual Installation Note Unpacking The WSS REC sensor is delivered in a cardboard box To protect the delicate sensor heads it is important to store it in the box until mounting Do not hit squeeze or try to remove the three black rubber hoods The sensor is protected against ESD static electricity but it is recommended to avoid static discharge through the connection wires during installation Legal information and responsibility DEIF takes no responsibility for installation or operation of the wind measuring system If there is any doubt about how to install or operate the WSS REC the company responsible for the installation or the operation of the product must be contacted The units are not to be opened by unauthorised personnel If opened anyway the warranty will be lost DEIF A S Page 4 of 14 55 User s Manual Installation Note 2 Mounting the wind senso

9. r Placing of the wind sensor Ideally the wind sensor should be placed far from large objects that might influence the measuring results however in practice this is normally not possible on a wind turbine The best result is achieved by placing the wind sensor at the top of a mast in the opposite end of the rotor Placing the sensor just above the nacelle and just behind the rotor is disadvantageous This may result in turbulence velocities and wind directions that are out of proportion to the actual undisturbed wind speed and wind direction The wind sensor is intended for installation on a vertical socket or a tube using the stainless steel tap mounting base See the drawing on the next page for dimensions of the tap The tap must not be removed from the wind sensor as this will damage the waterproof sealing and the warranty will become void Do not expose the plastic part of the wind sensor to any torque when mounting the sensor The tools used for fastening are only to be applied on the actual tap DEIF A S Page 5 of 14 55 User s Manual Installation Note IMPORTANT The stainless steel mounting base on the WSS sensor must be connected to earth e g the steel hull pipe thread Outer diameter 1 04inch 26 4mm 14 threads per inch To ensure that the measurement represents the precise wind direction relative to the turbine the wind sensor must be aligned correctly
