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").

5 mm (

") drill for the mounting holes.

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

technician.

English WIND

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.

 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.

Silicon

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. 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.

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

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.

some functions might not be available.

5.1.2 Adjusting damping

Sometimes too much information is meaningless and therefore to

change the rate that the information updates, we have something

called damping. The damping for wind angle, wind speed, boat

speed and VMG can be set individually for each function. You

can set the damping between d0 (0s) and d9 (1’20).

To change the damping, press SET and MINUS (for a sub / under

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.
