2 Installation

• The installation includes 6 major steps: 1. Read the installation and operation manuals. 2. Plan where to install the transducers and instruments. 3. Run the cables. 4. Install the transducers and instruments. 5. Take a break and admire your installation. 6. Learn the functions and calibrate your system.

Before you begin drilling ... think about how you can make the installation as neat and simple as your boat’s layout will allow. Plan where to position the transducers, WSI-box and instruments beforehand. Think about leaving space for additional instruments in the future.

 A few ”do not’s” that you should consider:  Do not cut the cables too short. Allow extra cable length at the WSI-box so it can be disconnected for inspection without having to disconnect all the attached cables.  Do not place sealant behind the display. The instrument gasket eliminates the need for sealant.  Do not run cables in the bilge, where water can appear.  Do not run cables close to fluorescent light sources, engine or radio transmitting equipment to avoid electrical disturbances.  Don’t rush, take your time.

• The following equipment is needed: Wire cutters and strippers. A small Philips and a small flat head screw driver. Hole saw for the instrument clearance hole - 63 mm (2½"). 1 5 mm ( /4") drill for the mounting holes.

If you are at all doubtful about the installation, obtain the services of an experienced technician.

2.1 Installing the instrument  Place the adhesive drill template on the desired location for the instrument. Drill the two holes using a 5 mm (1/4") drill for the two pin bolts. Use a 63 mm (2½") hole saw to machine the clearance hole for the instrument connection socket. Remove the template once you have finished drilling.

 Screw the two pin bolts into the back of the instrument  Put the instrument in place  Screw the two nuts from the back to secure the instrument.

Note! The two nuts must be hand-tightened only

 Run the Nexus Network cable from the WSI- box to the instrument.  If you want to cut the Nexus Network cable to length, disconnect the 4-pole jack plug and cut the cable. Peel off about 35 mm (1.4") of the cable insulation. Remove about 6 mm (1/4") from the 3 isolated wires (the 4th wire is an earth / screen). Attach the 4 cable protectors to the wires using a pair of flat pliers. Silicon  Connect the 4 cable protectors to the 4-pole jack plug as shown. Apply silicon paste on all locations as shown.

Note: This is necessary to avoid corrosion.

WIND English

 Apply silicon paste to the instrument connection pins at the back of the instrument. Press the jack plug onto the instrument pins. Press the cable in to the cable leads.  Mount the connection back cover with the screw. Do not over tighten.

2.1.1 Installing the instrument to the WSI-box All instruments are connected directly to the Nexus Network. They all use the same colour coded 4-pole jack plugs. (For instrument installation, see 2.2).

English WIND

2.1.2 Installing the instrument to the NX2 Server All instruments are connected directly to the Nexus Network. They all use the same colour coded 4-pole jack plugs.

2.1.3 Connecting to another Nexus instrument.

Use the connection cable, 0,3 m (1 ft ), to connect from the back of another Nexus instrument (use the “Nexus” side on the back – this may involve inserting two wires into the same connector). The other end then connects to the “Nexus” side on the back of this instrument.

3 First start (only in a Nexus Network)

3.1 Initialising the instrument At power on, the instrument will perform a self test. The display will first show all segments, then the software version number and the Nexus Network ID number.

At first power on after installation, you will be asked to press the SET button key [PrS KEY]. This will then give the instrument a logical and unique ID number on the Nexus Network.

WIND English

To initialise the instrument, press SET on all the installed digital instruments, one at the time but only after the instrument show OK.

Note: Always wait for the text ”Init OK” to be displayed, before you press SET on the next instrument!

The Server automatically gives the first unit ID number 16, then 17 and so on. The order in which you press SET is the same order as the instruments will be given a logical ID number on the Nexus Network.

The example shows that the instrument version number is 1.00 and the given logical ID number is 16.

3.2 Re-initialising the instrument If two instruments by mistake have the same ID number, this can cause disturbance and block the information on the Nexus Network.

To re-initialise the instrument, press MINUS and PLUS together during the power up sequence when the version and ID numbers are displayed.

4.1.1 Lighting

1. Press and hold PAGE 2 sec

2. Select Light Level with PLUS

3. Confirm the light level with SET

4.2 Main function “Top” data is the information displayed as the top function, this is a function that is selected in the set-up for the instrument and normally it is selected once and then it is not changed. The two options are:

[AWA] (Apparent Wind Angle) [TWA] (True Wind Angle), requires a log transducer. To change between these functions, see C12, 5.1.1.

4.3 Analogue function In the top example below, the wind scale is showing +/- 180 wind angle (5 degree / segment), this is usually enough information for the majority of day sailors. However there is also a 60 close-hauled function, which gives greater detail for upwind sailing. For closed-hauled function, se 5.1.1. Please note that the 60 scale does not work if the wind angle is greater than 60.

The text [APP = apparent] or [TRU = true] is displayed when PAGE is pressed.

English WIND

TWD 360 When a compass or GPS is connected to the Nexus Network, the text TWD 360 display shows True Wind Direction (geographical). To select Compass, See 5.1.6

4.4 Sub-functions Select sub-function with PLUS or MINUS.

4.4.1 True Wind Angle (TWA) The text [TWA] (True Wind Angle) and its value is displayed below. Note. If True Wind angle is selected as top function, this function will display the Apparent Wind Angle (AWA)

4.4.2 Apparent Wind Speed (AWS) The text [AWS] (Apparent Wind Speed) and its value are displayed below. The text [AWS] is toggled with the text [KTS] (KnoTS), [M/S] (Metres/S) or [BF] (Beaufort) depending on unit selected.

4.4.3 True Wind Speed (TWS) The text [TWS] (True Wind Speed) and its value are displayed below.

The text [TWS] (True Wind Speed) is toggled with the text [KTS] (KnoTS), [M/S] (Metres/s) or [BF] (BeauFort).

4.4.1 Boat speed The text [BSP] (Boat Speed) and its value are displayed below.

4.4.2 Velocity Made Good (VMG) The text [VMG] (Velocity Made Good) is WIND displayed with the actual boat speed made good against the wind. The water speed information from the log transducer is needed. The speed information can be taken from the log transducer or from Nexus Network. VMG = 0.0 knots when the true Wind angle is perpendicular to the boat.

English WIND

4.4.1 Radio strength indicator (RSI) The text [RSI] (Radio Strength Indicator) and its value are displayed below.

This is the strength of the radio signal between the Wind transducer and the WSI-box. The higher the value, the better the signal. In a normal installation you should have a value around 15- 35. If the value is below 10, you should reconsider the position of the WSI-box

4.4.2 Geographic wind direction (TWD) This function requires a compass transducer or a GPS antenna connected to the system. A HPC Compass can be connected direct to the Nexus Network. To select graphical reading of the TWD, press SET and PAGE. The display flashes. Then select the pointer as shown to the right with PAGE. Confirm with SET.

5.1.3 Selecting units for BSB, VMG and Wind Speed Select the function you want to change the unit for. Press SET and MINUS together and go to the unit selection with PAGE. Select the required unit with PLUS or MINUS and press SET to confirm. Available units for VMG and BSP: knots (KTS), km/h (K/h) or miles/h (m/h) Available units for Wind Sped: [KTS] for (Knots), [M/S] for (Metres/S) and [BF] for (Beaufort).

5.1.4 Calibration of the log transducer If the Wind instrument is installed with WSI-box or NX2 Server where the log is already calibrated, no further calibration is needed.

Calibration value for speed and distance (1.00 - 1.99)

Check calibration in your Nexus log and enter the same value. Go to the Boat speed function and press and hold SET for two seconds. The current calibration value is displayed. Increase with PLUS or decrease with MINUS. To exit the calibration mode and confirm the new value, press and hold SET for two seconds.

5.1.5 References for Speed Select the speed reference - log transducer, Nexus Network or SOG

BSP - Log signals direct in to the Wind instrument NEX – Boat speed information comes via the Nexus Network (Server or WSI-box) SOG – SOG from a GPS unit.

Go to the Sub-function BSP and press and hold SET for two seconds. The calibration value for boat speed id displayed. Press PAGE and the selected reference for Speed is displayed. Select the required reference with PLUS or MINUS and confirm by pressing SET for more than two seconds.

WIND English

5.1.6 References for Direction Select directional reference - compass transducer or COG.

HDC – Compass heading comes via the Nexus Network COG – COG from a GPS

Note! [COG] as reference will only operate properly when the boat is doing speed over ground. If COG is used and the boat is lying still, the TWD will show random readings.

5.1.7 Wind speed calibration This setting is for calibration of the wind speed. For a standard Twin-Fin transducer, the value should be 1.70. For Mono-Fin transducers, the calibration value should be 1.50. Go to a Wind speed function and press and hold SET for two seconds. The current calibration value is displayed. Increase with PLUS or decrease with MINUS. To exit the calibration mode and confirm the new value, press and hold SET for two seconds.

5.1.8 Adjusting the wind angle The mast top unit misalignment adjust value or the so called ”A- fault”, makes it possible to adjust any horizontal angle. Example: If the Wind angle is +4° when you sail/drive the boat straight into the Wind, set the calibration value to 356°.

Go to a Wind Angle function as a sub-function and press and hold SET for two seconds. The current calibration value is displayed. Increase with PLUS or decrease with MINUS. To exit the calibration mode and confirm the new value, press and hold SET for two seconds.

6 Maintenance and fault finding 6.1 Maintenance  To clean the instrument, use only a mild soap solution and rinse with water.  Do not use detergents or high pressure washer.  At least once a year, check all your connections and apply additional silicon paste at each connection point.  Always use the instrument cover for protection, when not in use.  Storing transducers and instruments when not in use for longer periods: It is advisable to remove the instruments and transducers, and store them inside the boat or at home at room temperature.

6.2 Fault finding Before you contact your NEXUS dealer and to assist them to give you a better service, please check the following points and make a list of:  All connected instrument and transducers, including their software version numbers.  Instrument software version number.  Nexus Network data bus ID numbers for each instrument (displayed at power up).

6.2.1 General In most cases, the reason for faults in electronic equipment is the installation or poor connections. Therefore, always first check that:

 Installation and connection is made per instructions for instrument and transducers, (see chapter 2).  Screw terminals are carefully tightened.  No corrosion on any connection points.  No loose ends in the wires causing short cuts to adjacent wires.  Cables for damage, that no cables are squeezed or worn.  Battery voltage is sufficient, should be at least 10 V DC.  The fuse is not blown and the circuit-breaker has not opened.  The fuse is of the right type.  Two instruments do not have the same ID number, (see chapter 3.2).

6.2.2 Faults and solutions 1. Wind: No reading [ --- ]  If inaccurate Wind data is received, check the connections (separate through deck connection or below decks connection), are properly made.  Make sure the transducer is aligned correctly, (see, 5.1.8).

2. Speed and distance functions: No reading [ --- ]  Selected speed reference should be BSP. See 5.1.5.  If you have a voltmeter available, you can check the condition of the transducer. When measuring with voltmeter make sure everything is connected, that the power is on and make sure the paddle wheel is rotating.

English WIND

 At the back of the instrument, measure between pin 4 and ground.  When not rotating, the value should be fixed at either about 0 or 12 V DC. When rotating very slowly, by hand, the value should flip between 0 and 12 V DC. When rotating faster, the value should average around 6 V DC.

Irregular values: Check the speed damping (SEA), (see C11, 5.1.2).
