WINDEnglishNX2 Wind transducerInstallation ManualThank you for choosing a NX2 product. Through this manual we would like to help youto install your new NX2 product. Please read through this manual carefully beforestarting your installation. This unique wind transducer provides both wind speed andwind angle relative the boat. If a Speed transducer is connected to the system, truewind speed and angle is computed. In addition, a compass or GPS antenna may beused to compute true wind direction relative North1 Installation1.1 LocationThe transducer should be mounted on a horizontal surface in the mast head. If themasthead is not horizontal a shim has to be added. An 15 shim for Seldén masts isavailable (art.no 67400-15).The wind transducer is using optical sensor technology performing digital PWM output.This technique provides high accuracy angle and wind speed measurements.2 Part specification1# Mounting instruction1# Warranty card1# Calibration certificate1# Wind transducer with 25 m cable1# Bracket5# Cable protectors (0,25 mm)3 INSTALLATIONThe transducer permits any type of horizontal mounting angle.Mount the unit by directing the pipe (1) down and backwards in the bracket (2). Securethe nut (3) towards the attachment BY HAND (tools can be needed when demounting).Attach the security clamp (4) behind the nut.The wind transducer connects to the Nexus Server.12-3

Insert the transducer into thebracket from front to back5. Tighten the lock nut by hand only(do not use any tool)6. Attach the security clamp7. Connect the cable12-4

WINDEnglish4 Electric installation4.1 Connections to the NX2 ServerIf you already have a Nexus Network i.e. a Server, it is more practical to connect thetransducer to the Server due to the single instrument cable installation. Note, set C71in Wind Data instrument to OFF (see Wind Data Manual)ServerTransducer4.2 Installing cableThe power cable is connected via a 3A fuse from the battery or at the boats fuse paneland direct to the instrument or Server. One red and one black power wire is included.Note, set in Wind Data instrument to C71 On (see Wind Data Manual)Always connect a 3 AMP fuse between Power supply and instrument.ScreenBlackGreenYellowWhiteRedTransducer3A Fuse12-5

EnglishWIND5 CalibrationIn order to get correct readings on your instruments, the transducer has to becalibrated. There are three things that has to be done:1. Enter the calibration values from the supplied calibration certificate into thecodes C56 to C62.2. Enter the misalignment of the transducer in calibration code C553. Make sure the calibration for wind speed in C54 is set to 1.70For information of how to enter the calibration values, se the instrument manual.6 SpecificationsTransducer cable 25 mPower suppIy 12V DC (10-16V)Power consumption 0,24 WCurrent consumption: 20mA @12VWind speed range 0.9-90 knots, 0.5-50 m/sAngle Accuracy Better than ± 2°Speed Accuracy ± 5%Temperature range Operating -5ºC to +70ºCStorage -20ºC to +80ºCWeight 260 g.6.1 Dimensions:12-6
