HPC Compass transducer
Installation Manual
Thank you for choosing a Nexus product. Through this manual we would like to help
you to install your new Nexus product. Please read through this manual carefully before
starting your installation. The six axis Nexus electronic compass measures the
magnetic field and the roll and trim. Out from that, the magnetic course is calculated.
An electronic compass is just as sensitive to magnetic disturbances as a magnetic
compass but has the benefits that the transducer can be mounted away from the
disturbances. From an instrument, the transducer can be automatic compensated.
1 Installation
1.1 Location of the HPC Compass
The transducer should be mounted horizontal or vertical (see pictures below). The
surface may be leaning ± 10 degrees from the horizontal or vertical plane.
It should be mounted perpendicular to the fore aft line (see picture on next page). Try to
mount the transducer reasonably well away from magnetic disturbances such as
objects containing iron, loudspeakers, window wipers etc. For safe distances, see page
11. The transducer does not have to be mounted in the centre of the boat. The
optimum position for the transducer is in the gravity centre of the boat. At that position
there may be magnetic disturbances, therefore the transducer normally is installed
more forward. The transducer is normally mounted below deck but its water resistant
enclosure allows for outside mount, which is preferable for some steel boats.
1.2 Check the location:
If you have large disturbance sources or a steel boat we recommend to connect the
transducer, mount it temporary and check the readout before the final mount.

2 Electrical installation
The transducer is connected to the Nexus Network, not to the Nexus Compass input. If
you do not have a Nexus Server the transducer is connected direct to the Network of
the NX2 Compass Data instrument, NX2 Wind Instrument or Nexus Autopilot Servo
Unit. After the electric installation you should check the readings on the instrument
before you proceed with the automatic compensation. If the readings are inaccurate
with more than 20º at any course, the transducer should be relocated.

3 Setup and deviation
The HPC Compass is adjusted and compensated from either the Multi Control or the
Compass Data instrument. (It is not possible to use the NX2 Race SW).
After installation:
1. Start to adjust the mounting angle of the HPC Compass. See below!
2. Auto deviate the HPC Compass (See C34 for Multi Control and C33 for
Compass Data)
3. Adjust the magnetic variation and misalignment (See C37 for Multi Control and
C36 for Compass Data)
3.1 Set-up from a NX2 Multi Control Instrument
3.1.1 C35 Adjust the Roll and Trim
In order to adjust mounting angle and adjust the roll and trim
values. Follow this procedure:
1. Make sure the boat is at 0° Roll and Trim
2. Press SET for more than 2 sec.
3. Go to C30 with PAGE
4. Go to C35 with PLUS
5. Press SET.
6. Press SET again within 5 sec.
Now the Mounting angle has been detected (horizontal or vertical)
Repeat step 5 and 6 above (press SET followed by SET) to fine
tune (set to zero) the Roll and Trim angles.
3.1.2 C34 Automatic compass deviation compensation (Auto DEV)
(Auto DEV) is performed by driving the boat in a circle up to 1¼ turn,
so that the magnetic deviation can be measured, and by that
compensated.
Select calibration code C34 (Auto DEV).
Drive the boat in a circle for 1 1/4 turn in calm water. When you start
the circle manoeuvre, press SET.
The un-deviated compass course will be shown in the display as
you turn. Complete the circle up to 1 ¼ turn.
When the manoeuvre is ready, press SET to store the deviation
value.
If the deviation is corrected (Auto DEV) will be displayed.
If the deviation is not corrected, an error message will be
displayed.
To verify the automatic compass deviation, perform an automatic
compass check (Auto CHK), (see 3.1.5).
Note: You will get the best result in calm water with a smooth turn
on the steering wheel independently of how the circle is
English HPC COMPASS

performed. When activated, you can stop the automatic compass
deviation at any time with a LONG press on SET.
3.1.3 C33 Magnetic deviation (00.0 VAR)
Magnetic variation. Maximum +/- 99.9°.
Easterly variation = underlining ( _ ) sign.
Westerly variation = minus ( - ) sign.
The local magnetic variation is usually printed in the sea chart.
3.1.4 C37 Compass misalignment correction (Adj)
Compass transducer misalignment correction or the so called
”A-fault”. Can be set between 000°and 359°. Allows 180°
reversed mounting if needed. Never mount the transducer in a
90° position relative to the boats fore-aft line.
To check the transducer position, sail/drive your boat in a straight
line towards two visible objects in a line.
Example: If the actual heading taken from the sea chart is 330°
and the compass displays 335°, then set calibration code C37
value to 360° - 5° = 355°.
3.1.5 C35 Automatic compass deviation check (Auto CHK)
(Auto CHK) is done by driving the boat in a circle up to 1 ¼
turn, after
(Auto DEV) is performed. The result will be
compared with (Auto DEV). If the deviation is less than 1,5*,
the average value from the comparison between (Auto DEV)
and (Auto CHK) will be stored.
If the check is OK, (Auto CHK) will be displayed.
If not an error message will be displayed.
Select automatic compass check (Auto CHK), press SET and
repeat the same circle manoeuvre as described in the (Auto DEV)
routine.
Note: As soon as you place any kind of ferrous items close to the
compass, the (Auto DEV) / (Auto CHK) routines should be
repeated. So if you have packed your boat for the vacation, think
about where you place ferrous items in relation to the compass
transducer.
3.1.6 C36 Cancel earlier performed compass deviation (Auto CLR)
To cancel/clear earlier (Auto DEV), press SET.
HPC COMPASS English
13-9
3.2 Set-up from a NX2 Compass Data Instrument
3.2.1 C34 Adjust the Roll and Trim
In order to adjust mounting angle and adjust the roll and trim
values. Follow this procedure:
1. Make sure the boat is at 0° Roll and Trim
2. Press SET for more than 2 sec.
3. Goto C30 with PAGE
4. Goto C34 with PLUS
5. Press SET.
6. Press SET again within 5 sec.
Now the Mounting angle has been detected (horizontal or vertical)
Repeat step 5 and 6 above (press SET followed by SET) to fine
tune (set to zero) the Roll and Trim angles.
3.2.2 C33 Autodeviation
(Auto DEV) is performed by driving the boat in a circle up to 1¼
turn, so that the magnetic deviation can be measured, and by that
compensated.
Select calibration code C33 (DEV Atd).
Drive the boat in a circle for 1 1/4 turn in calm water. When you
start the circle manoeuvre, press SET.
The un-deviated compass course will be shown in the display as
you turn. Complete the circle up to 1 ¼ turn.
When the manoeuvre is ready, press SET to store the deviation
value.
If the deviation is corrected (Auto DEV) will be displayed.
If the deviation is not corrected, an error message will be
displayed.
To verify the automatic compass deviation, perform an automatic
compass check (Auto CHK), (see 3.2.5).
Note: You will get the best result in calm water with a smooth turn
on the steering wheel independently of how the circle is
performed. When activated, you can stop the automatic compass
deviation at any time with a LONG press on SET.
3.2.3 C32 Magnetic deviation, VAR
Set the deviation direction first, i.e. [+E] (East) or [W] (West), then
enter the magnetic value in 1/10 of a degree.
English HPC COMPASS
13-10
3.2.4 C36 Adjust the Compass alignment
This function is used when the Compass is giving a constant
course error, i.e. it is not mounted exactly aligned as the boat (there
is no need to mount the transducer at the boats centreline). Make
sure that the local magnetic variation is entered before you make
the alignment adjustment, otherwise you are unable to see the
difference between local magnetic variation and alignment error.
The Compass may be installed reversed 180° , but never at
perpendicular, or 90° relative the centreline.
Press the SET and adjust [ADJ] the angle by entering the error. If
you want to add 5° enter 005°. If you want to subtract 5° enter 355°
(360- 5).
3.2.5 C34 Check the Autodeviation
This function is used to check your Autodeviation. Make a new
Autodeviation in calm sea (during the evening) as described above,
and you may (or not) take the boat the opposite direction as when
Autodeviated.
The text [CHK] starts flashing and a pointer will show you the
course where to end. When you have taken the boat through the
minimum 360° turn, press SET again, and if successful, the text
[CHK Atd] will appear again, otherwise, ERR 17 or ERR 19 will
appear, i.e. the difference between the last Autodeviation and this
Autocheck is to big to be accepted. Make a new Autocheck, and if
you still get ERR 19, make a new Autodeviation since the last one
was probably disturbed.
When the Autocheck is OK, the Compass will store the average
result from both Autodev and Autocheck.
3.2.6 C35 Clear the Autodeviation
If you by any reason prefer to reset the deviation created by the
Autodeviation function, press SET when text [CLR Atd] is
displayed, you are now asked to confirm the flashing text YES by
another press on KEY, or select no by use of PLUS or MINUS
button, then SET.

HPC Compass givare
Installationsmanual
Tack för att du valt Nexus Kompassgivare. I denna manual skall vi hjälpa dig att
installera din nya Nexus produkt. Läs igenom hela manualen innan du börjar med
installationen. Nexus HPC Compass är uppbyggd av sex axlar vilka mäter det
magnetiska fältet samt gravitation/lutning. Från denna information beräknas den
magnetiska kursen. En elektronisk kompass är lika känslig mot magnetiska störningar
som en vanlig magnetkompass men har den stora fördelen att den kan placeras på ett
stort avstånd från störningarna. HPC Compassen har också en inbyggd automatisk
kompensering.
1 Installation
1.1 Placering av din HPC Compass
Din HPC Compass kan monteras vertikalt eller horisontellt (se bilder nedan). Ytan som
kompassen monteras på kan luta upp till 10 grader från det horisontella eller vertikala
planet. Kompassen skall monteras vinkelrätt mot långskeppslinjen (se bild på nästa
sida). Försök att montera kompassen så långt som möjligt från magnetiskt störande
föremål så som högtalare, vindrutetorkare, motor etc. För säkerhets avstånd, se sidan
11. Kompassen måste inte placeras på båtens centrumlinje. Den mest optimala
placeringen är i båtens rörelsecentra. Denna plats är normalt utsatt för mycket
störningar varför kompassen monteras längre fram i båten. Kompassen monteras
normalt inne I båten men den är vattentät och kan monteras ute. Detta är oftast att
föredra på stålbåtar.
1.2 Kontrollera monteringsplatsen
Om du har stora störningar i din båt eller om du har en stålbåt, rekommenderar vi att du
kopplar in kompassen, monterar den tillfälligt och sedan kontrollera avläsningen av
kompassen. Om felet är för stort, bör kompassen flyttas.

3 Inställning och kalibrering
Din HPC Compass justeras från ett Multi Control instrument eller ett Compass Data
instrument. (Man kan inte autodeviera från NX2 Race mjukvaran).
Efter installation:
1. Starta med att justera monteringsvinkeln av din HPC Compass. Se nedan!
2. Autodeviera din HPC Compass (se C34 för Multi Control och C33 för
Compass Data)
3. Ställ in magnetisk variation och A-fel (se C37 för Multi Control och C36 för
Compass Data)
3.1 Inställning från NX2 Multi Control Instrument
3.1.1 C35 Justera Roll och Trim
För att justera monteringsvinkel av din HPC Compass, följ
proceduren nedan:
1. Se till att båten ligger plant med 0° Roll och Trim
2. Tryck SET i mer än 2 sek.
3. Gå till C30 med PAGE
4. Gå till C35 med PLUS
5. Tryck SET (kort).
6. Tryck SET (kort) igen inom 5 sek.
Nu har systemet detekterat monteringsvinkeln (horisontell eller vertikal)
Upprepa steg 5 och 6 (tryck SET följt av SET) för att finjustera
(sätta till 0°) Roll och Trim.
3.1.2 C34 Automatisk kompass deviering (Auto DEV)
Den automatiska kompassdeviationen sker genom att du aktiverar
funktionen [Auto DEV] samtidigt som du kör båten 1¼ varv i en
cirkel. Därvid uppmäts den magnetiska deviationen. Därefter sker
automatiskt en kompensering av deviationen.
Välj kalibreringskod C34 [Auto DEV].
Kör båten 1¼ varv i en cirkel vid lugnt väder. När du har påbörjat
cirkelmanövern trycker du på SET och fortsätter sedan i 1¼ varv.
Den odevierade kursen visas. Fortsätt manövern i 1¼ varv.
När manövern är slutförd trycker du på SET för att spara det
uppmätta deviationsvärdet.
Om deviationen har lyckats, visas [Auto DEV] igen.
Om deviationen ej har lyckats, visas ett felmeddelande.
För att kontrollera att deviationen är riktig kan du låta instrumentet
göra en kontroll med hjälp av funktionen [Auto CHK], se 3.1.5.
Anm a: Du uppnår det bästa resultatet vid lugnt väder samtidigt
som du låter båten göra en jämn sväng.
Anm b: Du kan avbryta den automatiska devieringen när som
helst genom att trycka på SET i mer än 2sek.
Svenska HPC COMPASS
13-8
3.1.3 C33 Missvisning (00.0 VAR)
Kompensation för missvisning. Max +/- 99,9°.
Ostlig missvisning = understrykningstecken [ _ ] framför
värdet.
Västlig missvisning = minustecken [ - ] framför värdet.
Missvisningen kan normalt utläsas i sjökortet
3.1.4 C37 Justering av kompassgivarens inriktning - ADJ
A-felet, dvs. vinkelfelet mellan kompassgivarens
”stävmarkering” och båtens centrumlinje kan justeras mellan
000°and 359°. Montera dock ej kompassgivaren 90° relativt
båtens centrumlinje.
Kontrollera kompassgivarens inriktning genom att styra båten
efter en enslinje. Om enslinjens riktning, enligt sjökortet, är t.ex.
330° och kompassen visa 335°, gör du enligt följande.
Räkna fram inriktningsfelet; 335 - 330 = 5°.
Räkna fram kalibreringsvärdet; 360 - 5 = 355°.
Välj kalibreringskod C37 [ADJ] och sätt denna till 355.
Tryck därefter på SET för att lagra värdet.
3.1.5 C35 Automatisk kompasskontroll - Auto CHK
Kompasskontrollen görs med funktionen [Auto CHK] på
samma sätt som i 3.1.5 ovan, efter det att du har utfört
deviationen med [Auto DEV]. Det uppmätta resultatet jämförs
därefter med resultatet från deviationen. Om skillnaden inte är
för stor kommer medelvärdet från de två mätningarna [Auto DEV]
och [Auto CHK] att användas som deviationsvärde.
Om kontrollen är godkänd, visas [Auto CHK] igen.
Om kontrollen ej är godkänd, visas ett felmeddelande
Välj funktionen [Auto CHK].
Tryck på SET och upprepa cirkelmanövern som beskrivits i
3.1.2 ovan.
3.1.6 C36 Ta bort tidigare gjord deviering - Auto CLR
Ta bort aktuell deviering genom att välja funktionen [Auto CLR]
och tryck på SET.
