Chapter 1:Operation  
1.1 Introduction  
Your ST40 Speed instrument provides:  
• Speedinformation(current, maximumandaverage), ineitherknots  
(KTS), miles per hour (MPH) or kilometres per hour (KPH).  
• Log and trip information. These are given in either nautical miles  
(NM), statute miles (M) or kilometres (KM).  
• Water temperature information. This is given in either degrees  
Celsius (°C) or Fahrenheit (°F).  
Note: The required speed, distance and water temperature units are  
selected during User calibration (see Chapter 4, Calibration).  
CAUTION  
Your instrument is calibrated to factory (default) settings when  
first supplied and must therefore be calibrated before use, to  
ensure optimum performance on your vessel. Do NOT use the  
instrument until the calibration procedures have been  
satisfactorily completed, using the procedures in Chapter 4,  
Calibration.  
Coloured bezel and Desktop Mounting Bracket options are available  
for your ST40 instrument. Contact your Raymarine dealer for further  
information.

Chapter 2:Maintenance and Fault Finding  
2.1 Maintenance  
Servicing and safety  
Raymarine equipment should be serviced only by authorised  
Raymarineservicetechnicians. Theywillensurethatservice  
procedures and replacement parts used will not affect performance.  
There are no user-serviceable parts in any Raymarine product.  
Some products generate high voltages, so never handle the cables/  
connectors when power is being supplied to the equipment.  
When powered up, all electrical equipment produces  
electromagnetic fields. These can cause adjacent pieces of electrical  
equipment to interact with one another, with a consequent adverse  
affect on operation. In order to minimise these effects and enable  
you to get the best possible performance from your Raymarine  
equipment, guidelines are given in theinstallation instructions, to  
enableyoutoensureminimuminteractionbetweendifferentitems  
ofequipment, i.e. ensureoptimumElectromagneticCompatibility  
(EMC).  
Always report any EMC-related problem to your nearest Raymarine  
dealer. We will use any such information to improve our quality  
standards.  
In some installations, it may not be possible to prevent the  
equipment from being affected by external influences. In general  
this will not damage the equipment but it can lead to spurious  
resettingaction, ormomentarilymayresultinfaultyoperation.  
AlwaysswitchoffthepowertoRaymarineequipmentbefore  
workingonit.  
When requesting service, please quote equipment Type, Model  
Number, Serial Number and, if possible, Software Release Issue. The  
Software Release Issue can be ascertained by means of the  
Intermediate Calibration facility, see Chapter 4, Calibration.

ST40SpeedInstrumentOwnersHandbook  
Instrument  
Certain atmospheric conditions may cause a small amount of  
condensation to form on the instrument window. This will not harm the  
instrument and will clear after the instrument has been switched on for a  
short period.  
Periodically clean your ST40 instrument with a soft damp cloth. Do  
NOT use chemical or abrasive materials to clean the instrument.  
Transducer  
Refer to the Installation and Maintenance instructions supplied with the  
transducer.  
Cabling  
Examine all cables for chafing or other damage to the outer shield and,  
where necessary, replace and re-secure.  
2.2 Fault finding  
Preliminary procedures  
If you appear to have a problem, first check the security of the  
connections at the rear of the instrument and reconnect any that are  
loose.  
Changesintheelectronicenvironmentmayadverselyaffectthe  
operation of your ST40 equipment. Typical examples of such changes  
are:  
Electrical equipment has recently been installed or moved aboard  
yourvessel.  
You are in the vicinity of another vessel or shore station emitting  
radiosignals.  
Fixing faults  
All Raymarine products are subjected to comprehensive test and  
quality assurance programmes prior to packing and shipping. However,  
if a fault occurs, the following guidelines may help to identify and  
rectifytheproblem.

Chapter 3: Installation  
Chapter 3: Installation  
This chapter describes how to install the ST40 Speed instrument, and  
associated speed transducer. The transducer is fitted in the hull of the  
vessel and is connected to the rear of the instrument.  
3.1 Planning your installation  
Determine the best positions for both transducer and instrument, such  
that the EMC installation guidelines and the Site requirements (below)  
are satisfied.  
EMC installation guidelines  
All Raymarine equipment and accessories are designed to the best  
industry standards forusein theleisuremarine environment.  
Their design and manufacture conform to the appropriate  
Electromagnetic Compatibility (EMC) standards, but correct  
installation is required to ensure that performance is not compromised.  
Although every effort has been taken to ensure that they will perform  
under all conditions, it is important to understand what factors could  
affect the operation of the product.  
The guidelines given here describe the conditions for optimum EMC  
performance, but it is recognised that it may not be possible to meet all  
of these conditions in all situations. To ensure the best possible  
conditions for EMC performance within the constraints imposed by  
anylocation, alwaysensurethemaximumseparationpossiblebetween  
different items of electrical equipment.  
Foroptimum EMC performance, it is recommended that wherever  
possible:  
All Raymarine equipment and cables connected to it are:  
At least 1 m (3 feet) from any equipment transmitting or cables  
carrying radio signals e.g. VHF radios, cables and antennas. In  
the case of SSB radios, the distance should be increased to 2 m  
(7 ft).  
More than 2 m (7 ft) from the path of a radar beam. A radar beam  
can normally be assumed to spread 20 degreesabove and below  
theradiatingelement.  
 
10  
ST40SpeedInstrumentOwnersHandbook  
The equipment is supplied from a different battery from that used for  
engine start. Voltage drops below 10 V in the power supply to our  
products, and starter motor transients, can cause the equipment to  
reset. This will not damage the equipment, but may cause the loss of  
some information and may change the operating mode.  
Raymarine specified cables are used at all times. Cutting and  
rejoining these cables can compromise EMC performance and so  
must be avoided unless doing so is detailed in the installation  
manual.  
If a suppression ferrite is attached to a cable, this ferrite should not  
be removed. If the ferrite needs to be removed during installation it  
must be reassembled in the same position.  
Suppression Ferrites  
The following illustration shows typical cable suppression ferrites fitted  
toRaymarineequipment. Alwaysusetheferritessuppliedby  
Raymarine.  
D3548-2  
Connections to Other Equipment  
If your Raymarine equipment is going to be connected to other  
equipment using a cable not supplied by Raymarine, a suppression  
ferrite MUST always be fitted to the cable close to the Raymarine unit.  
Tools required  
The tools required for fitting the standard ST40 instrument system are

The rear of the instrument is protected from water.  
3.2 Procedures  
Adapt these procedures as appropriate, to suit your individual  
requirement.  
CAUTION:  
Where it is necessary to cut holes (e.g. for cable routing and  
instrument mounting), ensure that these will not cause a hazard by  
weakening critical parts of the vessel’s structure. If in doubt, seek  
advice from a reputable boat builder.  
Fitting transducer  
Instructions for installing and maintaining the speed transducer are  
packed with it. Before attempting to install the transducer, read these  
instructions and theSite requirements for transducers described in this  
Chapter.  
 
14  
ST40SpeedInstrumentOwnersHandbook  
Running transducer cable  
Each transducer has a 9 m (30 ft) cable fitted with spade terminals for  
connection to the ST40 Speed instrument. Observing the following  
guidelines, run the cable to the instrument:  
If the cable has to be fed through the deck, always use a good quality  
deckgland.  
Where cables are fed through holes, always use grommets to prevent  
chafing.  
Secure long cable runs so they do not present a hazard.  
Wherever possible, route the cable away from fluorescent lights,  
engines, radiotransmittingequipment, asthesemaycause  
interference.  
Connections to the instrument  
Youcanconnectyourinstrument:  
Directly to the speed transducer as a stand-alone master instrument.  
When connected in this manner, the instrument must be connected  
to a suitable power source using the 1 m (3 ft) power cable provided.  
As part of a SeaTalk system either as a repeater or, with a transducer  
also connected as a system master. To connect to SeaTalk, you will  
need an additional SeaTalk Interconnection Kit, (Part No. E25028).  
When connected in this manner, power can be provided from the  
SeaTalk bus (e.g. from the autopilot).  
You can also connect the instrument to both the speed transducer and  
SeaTalk. When thus connected, the instrument will be the master speed  
instrumentfortheSeaTalksystem.  
If it is necessary to fit spade connectors to the transducer cable, do so as  
shown in the following illustration. Prepare the cable, as at (a), and fit  
the spade connectors, as at (b). When fitting each spade connector,  
ensure that wire strands do not extend beyond the rear of the spade  
connectorinsulation.

Chapter 4: Calibration  
Chapter 4:Calibration  
4.1 Introduction  
The procedures in this Chapter must be carried out before the  
equipment is used operationally, to optimise the performance of the  
instrumentwiththevessel.  
Calibration information is presented in flow chart form. The flow charts  
show the various calibration screens and key presses necessary to carry  
out calibration. All key presses are momentary unless otherwise stated.  
EMC conformance  
Always check the installation before going to sea to make sure that it is  
not affected by radio transmissions, engine starting etc.  
4.2 User calibration  
User calibration enables you to:  
Set the required units for speed readings. Either KTS (knots), MPH  
(miles per hour) or KPH (kilometres per hour).  
Set the required distance units. Either NM (nautical miles), SM  
(statute miles) or KM(kilometres).  
Select water temperature units. Either °C or °F, as required.  
Set the speed display response. Use higher response values when  
boating in conditions requiring rapid updates of the current speed  
(e.g. competition sailing or on power boats). Use slower response  
values when you require an average speed over a longer period of  
time(e.g. whencruising, especiallyinheavyseas).  
Set the correct speed reading, either by using a Cal factor screen to  
adjust the calibration factor, or by applying Speed Over Ground  
(SOG) as the current speed. Your vessel must be moving at 0.5 KTS  
or more and be receiving SeaTalk SOG data, to enable SOG to be  
applied as the current speed. This should be done only in conditions  
of zero tide and current.  
To carry out User calibration, power up the instrument then follow the  
procedure in theUser calibration flow diagram.
