System descriptionEA640 is a high performance hydrographic wide band single beam echo sounder. Theecho sounder is developed for hydrographic use in deep to medium depth waters.

For maximum flexibility and ease of operation, the EA640 echo sounders uses theMicrosoft Windows® 7 operating system. The EA640 software can be run on anymedium range Windows compatible commercial computer.

Wide band frequency sweep (FM) in combination with advanced signal processing givesan exceptionally good signal to noise ratio and range resolution.

The EA640 offers internal storage of all raw sample data. This includes all external inputsensor data for replay purposes. A highly flexible processing regime makes it possibleto log high density complex raw data for advanced post-processing. We recommendusing an additional external storage device.

You can set up the display to suit your special needs. You can choose differentpresentations on the screen for echograms, digital depth and other features. Save usersettings for different operations and use them again for similar operations.

EA640 supports a wide range of inputs from third party sensors and you can also exportthese data and data from EA640 to a wide range of different outputs.

Available frequencies span from 10 to 500 kHz. A variety of highly efficient transducersare available to suit all your operational needs from shallow to full water depths.

Operator Station descriptionThe Operator Station may be a panel computer or a separate computer with a display.The computer is based on a commercial design,but the software and hardware has been specified byKongsberg Maritime to suit the EA640 requirements.

WBT descriptionThe WBT is provided to transmit acoustic energy through water. This transmission andreception are commonly referred to as a ping. After each transmission, the transceiverreceives the echoes from the targets in the water and/or the seabed. These echoes arefiltered and amplified, and then converted to digital format.The Wide Band Transceiver (WBT) comprises a ruggedbox providing all necessary transmitter and receiverelectronics. The receiver is designed for low noise,and it can handle input signals spanning a very largeinstantaneous dynamic amplitude range.A high quality Ethernet cable connects the Wide BandTransceiver (WBT) to the Operator Station. The distance between the Operator Stationand the transceiver can be extended up to maximum 70 meters. If a longer cable isrequired, cut it in half, and insert an Ethernet switch to provide buffer amplification.Note

If more than one Wide Band Transceiver (WBT) is used, a small high capacity Ethernetswitch is required to connect the transceivers to the Operator Station.

The Wide Band Transceiver (WBT) requires an external power supply offering 12 to15 Vdc, minimum 5 A. A suitable power supply is provided with the delivery. Thetransceiver can also be powered by a large capacity battery.

Noise sources, page 14

Supply power requirementsObserve the general requirements related to the supply power.

The supply voltage to the equipment must kept within ±10% of the installation’s nominalvoltage.

Maximum transient voltage variations on the main switchboard’s bus-bars are not toexceed -15% to +20% of the nominal voltage (except under fault conditions).• Make and model: Kongsberg WBT• Voltage requirement: 12 – 15 VDC, 5A• Power supply:

– Voltage requirement: 115/230 VAC, 47 to 63 Hz, single phase, nominal– Maximum voltage deviation: 15%– Maximum transient: 20% of nominal voltage, recovery time 3 s– Power consumption: 100 VA (Approximately)

Cables and wiring requirementsCorrect wiring is crucial for the operational performance of the EA640.

All cables running between system cabinets located in different rooms and/or on differentdecks must be supported and protected along their entire lengths using conduits and/orcable trays. Note that the cables must not be installed in the vicinity of high-powersupplies and cables, antenna cables or other possible sources of interference.

All transducer cables must be run in steel conduits.

For more detailed information about cables and wiring, refer to the basic cablerequirements.

Compass deviation requirementsEA640 units that are installed on the bridge may have an effect on the compass.

Once the installation is complete, the vessel must be swung with the EA640 in bothoperative and inoperative modes.

The shipowner and captain are responsible for updating the compass deviation tableaccordingly with regard to the vessel’s national registry and corresponding maritimeauthority.

Noise sourcesThe operational performance of the EA640 Hydrographic single beam echo sounderdepends on the noise conditions. It is essential that the noise signature is as low aspossible.

The vessel’s hull, rudder(s) and propeller(s) must be thoroughly inspected in dry dockprior to installation.

Roughness below the water-line deformities in the shell plating and protruding obstaclescan create underwater noise. These sources of turbulence must be smoothed or removedas best as possible.

Note

It is especially important that the propeller(s) are not pitted or damaged.

Network securityIf a EA640 system is connected to a local area network, data security is important.

Equipment manufactured by Kongsberg Maritime is frequently connected to the vessel'slocal area network (LAN). When you connect a computer to a local area network youwill always expose the data on that computer. All other computers connected to the samenetwork may be able to access your data. Several threats may immediately occur:• Remote computers can read the data.• Remote computers can change the data.• Remote computers can change the behaviour of the computer, for example by

installing unwanted software.

Usually, two parameters are used to define the threat level:1 The likelihood that any remote connection will do any of the above.2 The damage done if a remote connection succeeds doing this.

Kongsberg Maritime has no information regarding the complete system installation onany vessel. Systems provided by Kongsberg Maritime are regarded as stand-alone offline


413764/B 15

systems. They are stand-alone even though they may be connected to a network forsensor interfaces and/or data distribution.

Note

No network safety applications are installed on any Kongsberg Maritime computers.The computers are thus not protected against viruses, malware or unintentional accessfrom external users.

Securing the EA640 system itself has no meaning unless there is a policy in place thatsecures all computers in the network. This policy must include physical access bytrained and trusted users. The customer/end user of the EA640 system will always bein charge of defining and implementing a security policy, and providing the relevantnetwork security applications.

Note

Kongsberg Maritime will not accept any responsibility for errors and/or damages causedby unauthorized use or access to the EA640.

If you wish to connect the EA640 system to the ship's local area network, you mustimplement the same security mechanisms on the EA640 computer(s) as for the rest ofthe network. This is a task for the network responsible person on board. Some keyelements here must be:• The same anti-virus protection on all computers, including routines for updating

this protection.• The same settings for the firewall on all computers.• Controlled physical access to computers on the network.• Trusted and trained operators.• Log-in access mechanisms.• Same policy for attaching peripheral equipment to the computers (USB devices,

hard drives etc).• Installation of programs on any computer in the network, verification that each

program is authentic.• Definition of which programs are allowed to run on each computer.• Logging mechanism of computer activity, and inspection of these logs.

How to define and implement these rules depends on each end user's network systemconfiguration, which again must be a result of the policies and threat levels the end userhas defined for the complete installation. For some products the network consists of onlyprocessor units and/or work stations, transceivers and a few sensors. On other vessels,larger computer systems can be installed to include numerous products and data systems.There must be one responsible person for the security of the system, large or small.

Installation summaryInstallation of the EA640 is a demanding task that requires careful preparations, anumber of specific procedures, wiring and required system settings.

ContextAn overall installation procedure is provided.Note

In order to obtain maximum safety and EA640 performance, it is very important that theinstallation procedures in this manual are complied to. You must do the tasks in the orderthey are described. The vessel owner must make sure that the installation shipyard holdsthe applicable competence to perform the installation, and that the applicable maritimeauthorities are available to verify and certify the installation.

Procedure1 Determine the physical location of the transducer (or transducers).

Necessary considerations must be taken to avoid acoustic and electric disturbances.2 Install each transducer.

Each transducer will penetrate the hull. For this reason, this is a crucial partof the installation. The installation shipyard must provide all necessary designand installation drawings, as well as the relevant work standards and mountingprocedures. If required, all documents provided by the shipyard for the physicalinstallation of the EA640 must be approved by the vessel’s national registry andcorresponding maritime authority and/or classification society. Such approval mustbe obtained before the installation can begin. The shipowner and shipyard doing theinstallation are responsible for obtaining and paying for such approval.

3 Install the EA640 system units.Note that some EA640 system units may be commercial. Unless ordered specificallythese are not included in the delivery, and must be purchased locally.

4 Install the cables between the EA640 system units.Observe the relevant cable plan, procedures, as well as the general requirements forcabling.

Avoid protruding objects near the transducer, page 21

Keep the transducer far away from the propellers, page 22

Mount the transducer at a safe distance from bow thruster(s), page 22

Summary and general recommendations, page 22

Introduction to transducer locationA single answer to the question "where to install the transducer" cannot be given.

The physical location of the transducer depends on the vessel's design and construction,how the hull is shaped, and how the water runs along the hull. There are however anumber of important guidelines, and some of these are even conflicting.

Note

The information here must be considered as general advice. Each EA640 installationmust be handled separately depending on the hull design and the other electrical andmechanical systems installed on the vessel.

Mount the transducer deepIn order to achieve the best possible EA640 performance, mount the transducer as deepas possible under the vessel’s hull.

There are several reasons for this recommendation.

Flow noise

Consider the situations when the vessel is unloaded, and pitching in heavy seas. Thevessel is riding high, and the bow may even be lifted out of the water. This will cause alot of air to follow the shape of the hull.

The upper water layers of the sea contain a myriad of small air bubbles created by thebreaking waves. In heavy seas the upper 5 to 10 metres may be filled with air, and thehighest concentrations will be near the surface. Air bubbles absorb and reflect the soundenergy, and they may in worst cases block the sound transmission altogether.


413764/B 21

Cavitation

Cavitation is the formation of small air bubbles close to the transducer face. The bubblesappear because the local pressure becomes negative during parts of the acoustic pressurecycles. The cavitation threshold increases with the hydrostatic pressure. The noise ismade when the bubbles implode.

Transmitting in air

The transducer must never be lifted free of the water surface. If the transducer isactivated when out of water it may be damaged beyond repair. Mounting the transducerat a deep position on the hull will in normally prevent this.

Slamming

Slamming happens if the vessel hull climbs out of the water in heavy seas. The force ofthe water when the hull falls down may push the transducer up, and may cause damageboth to the transducer and to its mounting. This is especially important for low frequencytransducers with large faces. The effect of slamming can be reduced by mounting thetransducer as deep as possible on the hull.

Note

Kongsberg Maritime AS takes no responsibility for any damages to the transducer, thecable or the mounting arrangement, caused by slamming.

Avoid protruding objects near the transducerObjects protruding from the hull will generate turbulence and flow noise. This willreduce the EA640 performance.

Protruding objects may be zinc anodes, transducers or even the vessel's keel. Holes andpipe outlets are also important noise sources, as well as rough surfaces caused by badwelding. Even traces of sealing compound, sharp edges, bolts or empty bolt holes willcreate noise. All these protruding objects may act as resonant cavities amplifying theflow noise at certain frequencies.

Do not place a transducer in the vicinity of protruding objects, and especially not closebehind them. Make sure that the surface of the transducer face, the hull plating and puttyaround the transducer is as even and smooth as possible. Mounting screws or bolts mustnot be extruding from the transducer, the installation hardware or the hull plating. Ifnecessary, grind and polish all surfaces.

Preparations

22 413764/B

Keep the transducer far away from the propellersThe propulsion propellers is the dominant noise source on most vessels. The noiseis easily transmitted through the water. This noise may often reduce the overallperformance of your EA640.

The transducer must be installed as far away from the propellers as possible. The bestpositions are therefore on the fore part of the hull. Positions outside the direct line ofsight from the propellers are best.

On small vessels we recommend mounting the transducer on that side of the keel wherethe propeller blades move upwards. This is because the propeller cavitation is weakeston that side. The cavitation starts when the water flows in the same direction as thepropeller blades. This is where the propeller blades move downwards.

Mount the transducer at a safe distance from bow thruster(s)Bow thruster propellers are extremely noisy. When you decide where to place thetransducer, you must consider the noise created by most bow thrusters.

When in operation, the noise and cavitation bubbles created by the thruster may makeyour EA640 Hydrographic single beam echo sounder useless, almost no matter where thetransducer is installed. When the bow thrusters are not in operation, the tunnel createsturbulence. If your vessel is pitching, the tunnel may be filled with air or aerated water inthe upper position and release this in the lower position.

In general, the transducer should therefore be placed well away from the bow thruster(s).

However, this is not an invariable rule. Certain thruster designs - combined with theirphysical locations on the hull - may still offer a suitable location for the transducer, evenclose to the thruster. If you are in doubt, consult a naval architect.

Summary and general recommendationsSome of the installation guidelines provided for transducer location may be conflicting.For this reason, each vessel must be treated individually in order to find the bestcompromise.

In general, the most important factor is to avoid air bubbles in front of the transducerface. For this reason, the recommended transducer location is normally in the fore part ofthe hull, well ahead of the noise created by the bow wave.

The maximum distance from the bow is normally equal to one third of the total waterline length of the hull.

Note

Mounting the transducer more than 10–15 meters from the bow may cause problemswith the turbulent flow.

If the vessel hull has a bulbous bow, this may well be a good transducer location, butalso in this case the flow pattern of the aerated water must be taken into consideration.The foremost part of the bulb is often a good location.

This applies to the vessel in normal trim and speed.

Preparations

24 413764/B

Important

The transducer must never be tilted backwards when the vessel is moving at normalspeed.

Do not place a transducer in the vicinity of protruding objects, and especially not closebehind them.

Make sure that the surface of the resulting installation is as smooth and streamlined aspossible.

Acoustic noise

TopicsContributing factors, page 25

Self noise, page 27

Ambient noise, page 29

Electrical self noise, page 29

Some means to reduce acoustic noise, page 30

Contributing factorsSeveral factors are contributing to the performance of the hydroacoustic equipmentused on board a vessel.

Factors contributing to the performance of the hydroacoustic equipment used on board avessel are:• The quality and properties of the transmitted signal• The quality of the receiving system• The operational settings made during operation• The properties of the target(s)• The signal-to-noise ratio

The majority of these factors can neither be controlled nor improved by meansof installation methods or transducer locations. The quality and properties of thetransmitting and receiving systems are key factors during our product development, whileour end user documentation aims to help the user to make the right filter settings duringoperation. As for the target properties, there is nothing any of us can do with those.

The signal-to-noise ratio, however, can be improved by making the correct choicesduring installation.

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used inscience and engineering that compares the level of a desired signal to the level ofbackground noise. It is defined as the ratio of signal power to the noise power, oftenexpressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates moresignal than noise. While SNR is commonly quoted for electrical signals, it canbe applied to any form of signal [...].

http://en.wikipedia.org/wiki/Signal_to_noise_ratio (September 2013)

The signal is the echo that we want to know something about, while the noise is anyunwanted signals or disturbances. The echo must be detected in the noise and therefore it

is necessary to keep the noise level is as low as possible in order to obtain long rangeand dependable interpretation.

The noise that contributes to the signal to noise ratio may be divided into the followingtypes of noise:• Self noise• Ambient noise• Electrical noise• Reverberation

A The transducer can pick up noise from• Biological disturbances• Interference• Cavitation• Propeller noise• Flow noise• Acoustic noise from other hydroacoustic systems

B The transducer cable is long, and may pick up electric noise from generators,pumps, cooling systems and other electric or electromechanical devices.

C The preamplifiers are very sensitive, and they can easily pick up electrical noisefrom internal and external power supplies. The preamplifiers are also vulnerable foranalogue noise created by their own electronic circuitry. Digital noise created bythe converter and processing circuitry can also create problems.

D Converters transform the analogue echoes to digital format.E Signal processing circuitry can create digital noise.


413764/B 27

Self noiseAny vessel equipped with a hydroacoustic system (for example echo sounder or sonar)will produce more or less self noise.

There are many sources of such self noise. We will here go into some details in order toanalyse the different sources of self noise on a vessel and how they may influence uponthe noise level of the hydroacoustic instruments.

Machinery noiseThe main contributor to machinery noise is usually the main engine on board the vessel.The contribution from auxiliary machinery may, however, be considerable, especially ifit is in poor shape. The machinery noise can be transmitted to the transducer as:• Structure-borne noise through the ship structure and the transducer mountings• Water-borne noise through the hull into the water to the transducer

Electrical noiseModern vessels are normally equipped with a lot of electric instruments such ashydroacoustic systems, radars, navigation systems, and communication equipment. Anyelectric instruments may in some cause electrical interference and noise. Internationalregulations and certifications are used to control and reduce this, but even these arelimited if the electrical systems are poorly installed and/or maintained.

Propeller noisePropeller noise is often the main source of noise at higher vessel speeds. Variable pitchpropellers or fast moving propellers usually make more noise than fixed propellers orslow moving propellers.

Propeller noise is usually water-borne. In some cases, however, shaft vibrations orvibrations in the hull near the propeller may be structure-borne to the transducer. If apropeller blade is damaged, this may increase the noise considerably.

Propeller cavitation is a severe source of noise. "Singing" propellers might be a source ofnoise, which interferes at discrete frequencies. In some cases static discharge from therotating propeller shaft may be quite disturbing.

CavitationCavitation is the formation of small air bubblesclose to the transducer face. The bubbles appearbecause the local pressure becomes negativeduring parts of the acoustic pressure cycles.The cavitation threshold increases with thehydrostatic pressure. The noise is made whenthe bubbles implode.

Cavitation noise may appear near extrudingobjects at higher speeds, but more often it is

caused by the propellers. Propeller cavitation is a severe source of noise. The cavitationstarts when the water flows in the same direction as the propeller blades. This is wherethe propeller blades move downwards.

In some cases a resonant phenomenon is set up in a hole near the hull. This sound willhave a discrete frequency, while all other flow noise will have a wide frequency spectrum.

Flow noise

The upper water layers of the sea contain a myriad of small air bubbles created by thebreaking waves. When the hull moves through water it will cause a disturbance, and thiswill generate friction. The friction zone is called the flow boundary layer. The flow inthis boundary layer may be laminar or turbulent.• The laminar flow is a nicely ordered, parallel movement of the water.• The turbulent flow is a disorderly flow pattern, full of eddies.

A Turbulent flowB Laminar flowC Air bubbles

Air bubbles absorb and reflect the sound energy, and they may in worst cases block thesound transmission altogether.

The boundary layer increases in thickness when it becomes turbulent. The boundarylayer is thin in the forward part of the vessel hull, and increases as it moves aft. Thethickness depends on ships speed and on the roughness of the hull. All objects stickingout from the hull, or dents in the hull, will disturb the flow and will increase the thicknessof the boundary layer. When the flow speed is high, the turbulence can be violent enoughto destroy the integrity of the water. Small voids or cavities in the water will occur andthis is called cavitation.

Rattle noise

Rattle noise may be caused by loose objects in the vicinity of the transducer, like fixingbolts. The rattle may also come from loose objects inside the hull.


413764/B 29

Interference

Interference from other hydroacoustic equipment on board the same vessel may be anannoying source of disturbance. Unless the same frequency is used for more than onepiece of equipment only the transmitted pulse will contribute to the interference.

In physics, interference is the phenomenon in which two waves superpose eachother to form a resultant wave of greater or lower amplitude. Interference usuallyrefers to the interaction of waves that are correlated or coherent with each other,either because they come from the same source or because they have the same ornearly the same frequency. Interference effects can be observed with all types ofwaves, for example, light, radio, acoustic, surface water waves or matter waves.

https://en.wikipedia.org/wiki/Interference_(wave_propagation), April 2016

Ambient noiseAmbient noise is usually not a limiting factor to the performance of sonars and echosounders.

The ambient noise may be split up as follows:• Sea noise: Air bubbles, seismic disturbances, waves, boundary turbulence, etc.• Biological noise: Fish, mammals• Man made noise: Other vessels, interference• Precipitation noise: Heavy rain or hail

In some areas, where many vessels operate together, the engine and propeller noise fromother vessels may be disturbing. Interference from hydroacoustic instruments locatedin other vessels may also be a limiting factor. The sea noise depends on the weatherconditions. In bad weather the sea noise can be quite high due to the waves.

Electrical self noiseElectrical or electronic self noise is picked up or generated in any other part of theequipment than the transducer.

Hum picked up by the transducer cables or picked up from the power supply is usuallythe most common source of electrical self noise. At higher frequencies – where ratherwide bandwidths are necessary – the noise from components, transistors or otheranalogue electronic may be a limiting factor.

Preparations

Some means to reduce acoustic noiseSeveral factors are contributing to the performance of the hydroacoustic equipmentused on board a vessel. Careful planning of the EA640 installation may reduce theacoustic noise.

Unfortunately, it is impossible to simply provide a number of specific procedures toreduce the noise.

An important factor is the physical location of the transducers. This depends on thevessel's design and construction, how the hull is shaped, and how the water runs alongthe hull. Other factors deal with other equipment mounted on board, and this will also bevessel dependant. At moderate ship speeds the machinery noise is usually dominant. Atmedium speeds the flow noise increases more rapidly and takes over, while at higherspeed the propeller noise will be the main contributor.

Note

The information here must be considered as general advice. Each EA640 installationmust be handled separately depending on the hull design and the other electrical andmechanical systems installed on the vessel.

Reducing flow noise• The shape of the transducer (or dome around it)

must be as streamlined as possible.• The hull plating in front of the transducer must be

as smooth as possible.

Important

Be especially aware of bilge keels and zinc alloyanodes. The keel must be rounded off withoutsharp edges. Neither extruding objects nor abrupttransitions must be present.

• Each transducer must be mounted with a small inclination angle (approximately 2degrees).

Reducing machinery noise• Each transducer must be installed as far away from the engine room as possible.• The main engine and relevant auxiliary engines and equipment must be fixed to rigid

foundations to avoid vibrations.• Any hull structure that may vibrate should be damped or coated to reduce the

vibrations.

The use of shock absorbers or floating rafts may sometimes reduce this noise. Thestructure-borne noise may be reduced by isolation, for example by providing vibrationclamping between the transducer and the hull structure.


413764/B 31

Reducing propeller noise• Each transducer must be installed as far away from the propellers as possible.• Sufficient clearance between the propellers and the hull, the rudder and the keel must

be provided.• Place the zinc alloy anodes in places where the water flow is the least disturbed.• Ensure that the propellers blades are correctly designed and without damages.• The use of a baffle between the propellers and the transducer may reduce noise

appreciably.• Static discharges caused by the rotating propeller shaft may be removed by proper

grounding or by mounting a coal brush from the shaft to vessel ground.

Reducing rattle noise

Ensure that no parts near the transducers can rattle as a result of water flow or vibrations.

Reducing interference

Interference from the transmission pulses from other hydroacoustic instruments onboard the vessel is difficult to avoid. The problem may be reduced by choosing theworking frequencies carefully and to some extent by separating the different transducers.On vessels with a large number of separate hydroacoustic systems installed and insimultaneous use, a separate synchronizing system (for example the K-Sync) shouldbe considered.

Reducing electrical noise• Place the transducer cables in a metal conduit from the transducer to the WBT.

Terminate the conduit as close to the transducers and WBT as possible.• Make sure that all units are properly grounded, as this is important to avoid electrical

noise.• Use shielded cables with correct grounding.• Separate EA640 cables from other cables with high voltages, large currents or

transients. Place all high voltage power cables in metal conduits.

A Service access (optional)B To transceiverC Steel conduitD Bushing, penetrates the hull platingE WasherF Rubber gasketG Packing nutH Cable service loop over the transducer

Context

The installation shipyard must provide allnecessary design and installation drawings,as well as the relevant work standardsand mounting procedures. If required, alldocuments provided by the shipyard for thephysical installation of the EA640 must beapproved by the vessel’s national registryand corresponding maritime authorityand/or classification society. Such approvalmust be obtained before the installationcan begin. The shipowner and shipyarddoing the installation are responsible forobtaining and paying for such approval.

Important

Finalize the steel conduit installation before you pull the transducer cable through it.Make sure that there are no spatter, sharp edges or protruding objects that can damagethe transducer cables. If a cable is damaged, and penetrated by water, the transducermay be damaged beyond repair.

Procedure1 Based on the vessel drawings, the physical properties of the decks and bulkheads,

and the physical locations of the WBT and the transducer, design the steel conduit.

The steel conduit must preferably be straight. Start the conduit immediatelyabove the transducer, and terminate it well above the water line. If you mustintroduce bends on the steel conduit, take the minimum cable bending radius intoconsideration.

2 Manufacture the steel conduit according to the relevant production standards.3 Mount the steel conduit.


413764/B 43

Secure the steel conduit to decks and/or bulkheads with welds. Observe relevantrequirements and guidelines from the classification society, and make sure that theconduit is properly supported, strong and watertight.Note

The quality of the welding is critical to the safety of the vessel. Welding must onlybe done by a certified welder.

4 If relevant, allow the maritime authority and/or classification society to inspect andapprove the design and the installation of the steel conduit.

Installing the transducer(s)The installation of the transducer (or transducers) is a key task for successful use of theEA640 Hydrographic single beam echo sounder. Not only will you need to penetratethe vessel’s hull, you must also to select a physical location for maximum performanceand minimum acoustic and electric noise.

PrerequisitesTo get a full overview of the installation, you need all relevant vessel drawings. You alsoneed the drawings provided for each transducer.

ContextNecessary information for the installation of each transducer can be found in the end-userdocumentation provided with the transducer.

Procedure1 Determine the physical location of the transducer.

The decision must be based on:• The vessel drawings• The shape and properties of the hull

Make sure that all possible considerations are made to reduce noise.2 Based on the shape of the transducer housing, and the mounting devices available,

determine the installation method.3 Design, manufacture and mount the necessary fairing, installation blister, keel box

and/or tank that is required to mount the transducer.4 Design, manufacture and mount the steel conduit for the transducer cable.5 Unpack the transducer from its transport crate.6 Position the transducer under the mounting location.7 Pull the transducer cable up through the steel conduit.

8 Tighten the packing nut on the cable gland properly to avoid leaks.9 Mount the transducer.10 Seal the top of the steel conduit to prevent water leaks.11 Connect the transducer cable to the WBT.12 If your vessel will operate in waters with a lot of marine growth, consider applying

a thin layer of anti-fouling paint to the transducer face.

Installing the transducer on a blister or dropkeelWhen all the preparations have been made, observe this procedure for the mounting ofthe transducer If required, additional and more detailed procedures must be provided bythe installation ship yard.

Prerequisites• The physical location of the transducer has been determined.• The steel conduits are installed.• A suitable fairing is designed and mounted.

Note

Whenever relevant, all drawings as well as the physical installation of each device mustbe approved by the vessel’s national registry and corresponding maritime authorityand/or classification society.

The following special tools are required for this installation:• Torque wrench for the mounting bolts• Loctite 270 (permanent high-strength threadlocker)

Context

This installation arrangement assumes that you can access the inside of the blister ordrop keel to mount the nuts. If this is not the case, the transducer must be mounted withthreaded steel rods welded to the bottom of the blister.

Connecting a synchronization cable to the Operator Station using an RS-232 serialinterfaces, page 56

Connecting one or more transducers to the WBTDepending on your operational requirements for the EA640, one or more transducersmust be connected to the WBT.

Prerequisites

It is strongly recommended to lay a steel conduit from the cable gland above thetransducer to the EA640 transceiver, and to pull the transducer cable through this conduit.

There are several reasons for this.• It will make it easier at a later stage to replace the transducer.• It will protect the cables.• Noise and interference from other electrical equipment is greatly reduced.• The risk of flooding is greatly reduced when the steel conduit is terminated above

the water line.

With a steel conduit the installation will satisfy the European Union regulations forelectromagnetic compatibility (EMC) interference. Without a steel conduit, there is arisk of reduced EA640 performance.

Context

The WBT used by the Kongsberg EA640 can be set up to work with maximum four -4-operational frequencies. This means that you can use four single frequency/single beamtransducers or two dual frequency transducers.

The transducer is connected to a terminal block under a panel plate on the rear of theWBT. The connectors are a part of the WBT delivery.

Procedure1 Pull the transducer cable through the steel conduit.2 Make sure that an ample length of the transducer cable is available for maintenance

and replacement.3 Cut the transducer cable.4 Find the panel for the rear side of the WBT, the cable glands, the blind plugs and

the nuts.


413764/B 53

5 Make sure you use the correct size cable gland according to the cable size. Thecable glands are included in the delivery.

6 Use a blind plug to cover the points not in use.7 Pull the transducer cable through the cable glands.8 Remove the insulation on the shield in the transducer cable.

9 Cut the shield, to just cover the seal.

10 Remove the insulation on the wires in the transducer cable.11 Add an end sleeve to the wires.12 Fit the cable gland.


54 413764/B

13 Connect the conductors in the transducer cable to the correct pins in the plugs,using the pin-out and the ship’s cable plan. Check the license information to seewhich transducer to install where.

14 Connect the plugs to P1 and P2.15 Make sure the conductive gasket is still attached to the WBT.


413764/B 55

16 Fasten the panel.

Connecting power and ground to the WBTThe EA640 WBT is powered by a dedicated power supply connected to the AC mains,or from a suitable battery for DC operation. The unit must be properly grounded.

Context

The power for the WBT is provided by a separate power supply. It is normally connectedto an uninterruptible power supply, and will automatically detect the mains voltage (230or 115 VAC) when connected. The output from the power supply is connected to the+12 VDC input socket on the WBT. The AC and DC power cables are provided withthe power supply.

Procedure1 Connect the DC cable from the power supply to the +12 Vdc socket.

If you wish to operate your WBT from a DC supply, you can use any suitablebattery providing +12 to +15 Vdc.

2 Connect the AC mains plug on the power supply to the bulkhead power outlet (oran uninterrupted power supply).

3 Connect the grounding cable from the nearest grounding point to the dedicatedterminal on the WBT.


56 413764/B

Connecting the WBT and the Operator StationThe Operator Station is connected to the WBT using a high speed Ethernet cable.

Context

Note

It is very important that a high quality Ethernet cable is used. You must use CAT-5E STP(Shielded Twisted Pair) quality or better. Using cables with lower bandwidth capacitywill reduce the EA640 performance.

Procedure:• Connect the Ethernet cable from the Operator Station to the Ethernet socket on the

WBT.• If you have a system with more than one WBT you need a switch.

Tip

We recommend having the switch in the sonar room, close to the WBTs. This givesyou only one Ethernet cable from the sonar room to the Operator Station.

Connecting a synchronization cable to the Operator Stationusing an RS-232 serial interfacesAn RS-232 serial line connection using the Request To Send (RTS) and Clear ToSend (CTS) signals is common way to connect the EA640 to external devices forsynchronisation purposes. The cable is connected to the serial line adapter on OperatorStation.

Context

Note that this cable does not support all the signals in the standard RS-232 specification.

Unless otherwise specified, these cables must be provided by the installation shipyard.

Important

Observe that long runs of unshielded cable will pick up noise easily. This is becausethe RS-232 signals are not balanced.
