1.1 Introduction

Your ST40 Speed instrument provides:

• Speed information (current, maximum and average), in either knots

(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.

Chapter 2: Maintenance and Fault Finding

2.1 Maintenance

Servicing and safety

• Raymarine equipment should be serviced only by authorised
Raymarine service technicians. They will ensure that service
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 the installation instructions, to
enable you to ensure minimum interaction between different items
of equipment, i.e. ensure optimum Electromagnetic Compatibility
(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
resetting action, or momentarily may result in faulty operation.

• Always switch off the power to Raymarine equipment before
working on it.

5

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.

6 ST40 Speed Instrument Owner’s Handbook

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.

Changes in the electronic environment may adversely affect the
operation of your ST40 equipment. Typical examples of such changes
are:

• Electrical equipment has recently been installed or moved aboard
your vessel.

• You are in the vicinity of another vessel or shore station emitting
radio signals.

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
rectify the problem.

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 for use in the leisure marine 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.

9

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
any location, always ensure the maximum separation possible between
different items of electrical equipment.

For optimum 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 degrees above and below
the radiating element.

10 ST40 Speed Instrument Owner’s Handbook

• 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
to Raymarine equipment. Always use the ferrites supplied by
Raymarine.

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
shown in the following illustration.

The transducer should:

• Be ahead of the propellers (by a minimum of 10% of the water line
length ).

• Be at least 150 mm (6 in) away from the keel (ideally ahead of the
keel if a sailing yacht).

• Be as near as possible to the centre line of the vessel.

• Be clear of other through-hull fittings or projections.

• Have sufficient clearance inside the hull to fit the nut.

• Have 100 mm (4 in) of headroom to allow for withdrawal.

The transducer should be sited within the clear water flow areas
indicated by the shaded areas in the following diagram.

CAUTION:

The presence of moisture at the rear of the instrument could cause
damage either by entering the instrument through the breathing
hole or by coming into contact with the electrical connectors.

Each instrument must be positioned where:

• It is easily read by the helmsman or navigator

• It is protected against physical damage

• It is at least 230 mm (9 in) from a compass

• There is reasonable rear access for installation and servicing

• 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.

instructions and the Site requirements for transducers described in this
Chapter.

14 ST40 Speed Instrument Owner’s Handbook

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
deck gland.

• 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, radio transmitting equipment, as these may cause
interference.

Connections to the instrument

You can connect your instrument:

• 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
instrument for the SeaTalk system.

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
connector insulation.

Instruction Sheet, which is included with the Desktop Mounting
Bracket.

3.3 Calibration requirement

Once installation is complete and before you use your instrument, carry
out the calibration procedures detailed in Chapter 4, Calibration.

19

D4646-1

20 ST40 Speed Instrument Owner’s Handbook

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
instrument with the vessel.

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. when cruising, especially in heavy seas).

• 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.

21

To carry out User calibration, power up the instrument then follow the
procedure in the User calibration flow diagram.
