Failure to observe this may result in permanent damage tothese display units.This handbook is divided into three chapters as follows:Chapter One provides an overview of the scanner installation. It includessections on Unpacking and Inspecting the Components, Selecting the ScannerSite and a description of the Cable Runs.Chapter Two provides detailed instructions on how to mount and connect eachtype of scanner.Chapter Three provides instructions on how to perform the system checks,alignment and adjustments.154_2c1.p65 13/05/99, 13:171
2Pathfinder Radar ScannersEMC installation guidelinesAll Raytheon equipment and accessories are designed to the best industrystandards for use in the leisure marine environment.Their design and manufacture conforms to the appropriate ElectromagneticCompatibility (EMC) standards, but correct installation configuration isessential to maintain EMC performance and CE compliance. Although everyeffort has been taken to ensure that they will perform under all conditions, it isimportant to understand what factors could affect the operation of the product.To avoid the risk of operating problems, all Raytheon equipment, and cablesconnected to it, should be installed as follows:• Ensuring you follow the installation instructions in Chapter 2, particularlywith reference to earthing details.• With at least 1 m (3 ft) from any equipment transmitting or cables carryingradio signals e.g. VHF radios, cables and antennas. In the case of SSB radios,the distance should be increased to 2 m (7 ft).• Avoiding the beam from another radar scanner. A radar beam can normallybe assumed to spread 20 degrees above and below the radiating element.• The equipment should be supplied from a different battery than the one usedfor engine start. Voltage drops below 10.7 V in the power supply to ourproducts can cause the equipment to reset. This will not damage theequipment, but will cause the loss of some information and can change themode of operation.• Genuine Raytheon cables must be used at all times. Cutting and rejoiningthese cables can degrade EMC performance and must therefore be avoidedunless specifically detailed in this handbook.• If a suppression ferrite is attached to a cable, this ferrite must not be removed.If the ferrite has to be removed during installation it must be reassembled inthe same position. Section 2.1 Installing the Radome Scanner includesinstructions on fitting a ferrite.The following illustration shows a typical range of suppression ferrites fitted toRaytheon equipment.154_2c1.p65 13/05/99, 13:172
Chapter 1: Overview 3If your Raytheon equipment is going to be connected to other equipment usinga cable not supplied by Raytheon, a suppression ferrite MUST always be fittedto the cable close to the Raytheon unit.1.2 Unpacking and inspecting the componentsUnpack your system carefully, to prevent damage to the equipment. It is goodpractice to save the carton and packing for future use, in case you need to returnthe unit for service.Check that you have all the correct system components. These depend on yoursystem package, as detailed in the following tables.Radome scannersItemItemItemItemItem Part No.Part No.Part No.Part No.Part No. SuppliedSuppliedSuppliedSuppliedSupplied OptionOptionOptionOptionOptionwith:with:with:with:with: for:for:for:for:for:Radome ScannersRadome ScannersRadome ScannersRadome ScannersRadome Scanners2D 18" 2 kW Radome Scanner M92650 US Version -2DE 18" 2 kW Radome Scanner M92650E European Version -4D 24" 4 kW Radome Scanner M92652 - -Radome Scanner Accessories Radome Scanner Accessories Radome Scanner Accessories Radome Scanner Accessories Radome Scanner Accessories (2D & 4D Variants)Inter-unit cable 15 m heavy M92668 4D -Inter-unit cable 25 m heavy M92669 - BothInter-unit cable 10 m light M92692 2D (US version) -Inter-unit cable 15 m light M92720 2D (Europe version) -Extension cable 5 m M92699 - BothExtension cable 10 m M92700 - BothMast Mount 18" Scanner M92722 - 2DMast Mount 24" Scanner M92698 - 4DRadar Interface adapter M92721 - 2DTo fit radome to M88390 type 18" mast mountRadome mounting interface plate M92731 - 2DSupplied with HSB Series Display UnitSupplied with HSB Series Display UnitSupplied with HSB Series Display UnitSupplied with HSB Series Display UnitSupplied with HSB Series Display UnitFerrite Clamp R55007 - Both154_2c1.p65 13/05/99, 13:173

Chapter 1: Overview 7Selecting the best location for the scanner unit requires careful consideration ofthe following points, to ensure reliable and trouble free operation:Note: In order to minimise potential interference to other systems on boardship (EMC), it is advisable to mount the scanner on a part of the boat that isinsulated from the ship’s battery negative. If you cannot do this, and encounterproblems, you can fit insulating bushes between the scanner and its mountingbracket.•Height: The scanner unit should normally be mounted as high as practicalabove the waterline, for three reasons:- Safety -the scanner should above head height of personnel. This avoidsmechanical danger and electromagnetic contact, particularly with theeyes.- Radar operates at the line-of-sight, so a high mounting position givesbetter long range performance.- Surrounding large objects, in the same horizontal plane, can interfere withthe radar signal and cause blind areas or shadow sectors and false targetson the radar screen (see below).However, do not mount the scanner so high that it is affected by the pitchingand rolling of the vessel. In addition, you may need to lower the scanner toavoid creating a shadow sector.•Access: The scanner unit site should be easily accessible to allowmaintenance to be carried out safely.•Magnetic compass: Mount the scannner unit at least 1 m away from amagnetic compass.•Cable run: The maximum length of cable between the display unit and thescanner unit should not normally exceed 20 m (60 ft) for radome scanners, or15 m (45 ft) for open array scanners. If you need to use a longer cable powercable lengths must be considered, refer to Section 1.4 Cable Runs.•Shadow sectors and false echoes: Mount the scanner away from largestructures or equipment, such as the fly bridge, large engine stacks,searchlights, horns, or masts. It is particularly important to avoid shadowsectors near the bow. Raising or even lowering the scanner may help toreduce these effects.In shadow areas beyond the obstruction there will be a reduction of the beamintensity, although not necessarily a complete cut-off; there will be a blindsector if the subtended angle is more than a few degrees.In some shadow sectors the beam intensity may not be sufficient to obtain anecho from a very small object, even at close range, despite the fact that alarge vessel can be detected at a much greater range. For this reason the154_2c1.p65 13/05/99, 13:177
8Pathfinder Radar Scannersangular width and relative bearing of any shadow sector must be determinedat installation. Sometimes shadowing can be seen by increasing the radargain until noise is present. Dark sectors indicate possible shadowed areas.This information should be posted near the display unit and operators mustbe alert for targets in these blind sectors.It should also be noted that wet sails create shadow areas and thus sail boatoperators should be aware that radar performance may reduce in rain.If you mount the scanner on a mast, echoes from the mast may appear on theradar display. These can be minimised by placing absorbing material, suchas a block of wood, between the scanner and mast.•Platform rigidity/stability: The scanner platform should not twist (causingbearing errors) or be subject to excessive vibration.•Heat/fumes: Mount the scanner away from the top of exhaust stacks, sincethe scanner and cables can be damaged by excessive heat and the corrosiveeffects of exhaust gases.For open array scanners you should also consider the following points:•Mounting Platform: The platform must be mechanically secure andcapable of supporting the mass and inertia of the open array scanner. Thecomplete unit weighs 30 kg.• The site must be clear of ropes and moving rigging.• Sufficient clearance must be allowed to fully open the open array pedestalfor maintenance.Mounting surface: sailboatsThe scanner unit can be installed on a mast platform, an arch, or a bridgestructure. Make sure that the platform surface is flat and the scanner unit drainhole (radome scanners) is not obstructed. Raytheon recommends that radomescanner units are best suited for sailboat operation as open array systems aremore difficult to protect from ropes and sails.For sailboat installations, Raytheon offers a universal mast mount kit for eachradome scanner type. This optional mount is used to fit a radome scanner to aflat surface on a mast with a minimum diameter of 60 mm (2½ in). When usingthe mast mount kit, appropriate hardware should be used for the style andstructure of the mast aboard the vessel. If there is any doubt concerning theappropriate type of hardware, consult your boat dealer or representative fortheir recommendations.Depending on the type of sailboat, a radar scanner guard should be installed ifthe sails could touch the scanner or platform. Without a proper radar guard themounting platform and the radar scanner could be severely damaged.154_2c1.p65 13/05/99, 13:178
Chapter 1: Overview 9Mounting surface: power boatsOn many small vessels the scanner unit can be installed on a mast platform, anarch, or a bridge structure, but take care to follow the scanner site guidelines,particularly regarding height. If necessary, construct a radar mounting platformto obtain a sufficiently high mounting position. Make sure that the platformsurface is flat and the scanner unit drain hole (radome scanners) is notobstructed. Ensure the platform is strong enough to support the maximumshock loads likely to occur.Setting the radiation planeThe scanner unit should be mounted so that the array rotates parallel to thewaterline. The radar beam is approximately 25° wide in the vertical direction,providing good target detection during the vessel’s pitching and rolling.Planing hull vessels, and some displacement hull vessels, adopt a higher bowangle when the vessel is at its cruising speed. In many cases this substantiallyalters and raises the radar’s main radiation plane, and can cause poor detectionof nearby targets. It may be helpful to lower the radar beam back towards theparallel, by shimming the rear of the radar, so that the beam points slightlydownwards with respect to the waterline when the vessel is at rest.The shims may be made from aluminium plate wedges, simple flat washers, oran angled wooden block. For thick shims, you may need longer securing boltsthan the M8x40 bolts supplied with the radome scanner, or the M10 studdingsupplied with the open array scanners.154_2c1.p65 13/05/99, 13:179
10 Pathfinder Radar Scanners1.4 Cable runsYou need to consider the following before installing the system cables:– You need to fit the inter-unit cable and the power cable.– All cables should be adequately clamped and protected from physicaldamage and exposure to heat - avoid running cables through bilges ordoorways, or close to moving or hot objects.– Acute bends must be avoided– Where a cable passes through an exposed bulkhead or deckhead, awatertight gland or swan neck tube should be used.– Avoid cutting and re-joining cables (if necessary, refer to the notes below)You need to run the following cables:CAUTIONDo not pull the cable through bulkheads using a cord attached to theconnector. This could damage the connections.•Inter-unit cable . A vinyl-covered and shielded cable is supplied with theradome scanner unit. The cable has a connector plug at one end forconnecting to the display unit or extension cable; the other end of the radomescanner cable is fitted with an 8-way plug and power cores (covered by aclear protective sleeve) for connecting to the scanner.For open array scanners, various length cables are available. These cableshave a connector plug at one end for connecting to the display unit orextension cable; the other end is prepared ready to fit to the power and signalconnectors (see Section 2.2)• Power cable, the scanner receives power via the display unit. The powercable is supplied with the display unit. However, cable details are provided inthis section.Rejoining CablesYou should avoid cutting and re-joining cables. If this is necessary you must:• Fit a ferrite on each side of the join. The specific ferrite to use depends on thecable type - contact Raytheom Marine for details.• Take care not to damage any of the wires. Make sure that all the wires and, inparticular, the screen are reconnected correctly.If you are mounting the scanner on the mast of a sailboat, and will need tounstep the mast, you should install a suitable junction box inside the boat.On a radome scanner, the junction box should provide an 11- or 13-wayterminal strip, depending on the number of power cores in your cable, with a10 A rating. Also, you should keep the length of the un-screened coaxial coresto less than 30 mm to maintain EMC conformance.154_2c1.p65 13/05/99, 13:1710
Chapter 1: Overview 11On an open array scanner, the junction box should provide a 13-way terminalstrip with a 20 A rating for power cores. It is essential that all 4 power cores areconnected and that the connection is of very low resistance as considerablepower passes through this connection. Also, you should keep the length of theun-screened coaxial cores to less than 30 mm to maintain EMC conformance.Inter-unit cableThe inter-unit cable entrance is at the rear of the scanner unit. If the unit ismounted on a hollow mast the cable may be run inside the mast and then fedthrough the radar’s cable entrance. Make sure that the cable does not chafewhere it enters and exits the mast.Note: Route the cable from the display up to the scanner, since this will requirethe smallest clearance hole.CAUTIONThe display connector on the inter-unit cable is a moulded plug thatcannot be replaced. DO NOT remove this moulded plug.The inter-unit cable, for connecting the scanner to the display unit, depends onyour scanner package as follows:Scanner PackageScanner PackageScanner PackageScanner PackageScanner Package Inter-Unit CableInter-Unit CableInter-Unit CableInter-Unit CableInter-Unit Cable2D (US) 10 m light (2 power cores)2DE (European) 15 m light (2 power cores)4D 15 m heavy (4 power cores)5S 5 m, 15 m or 5 m + 10 m extension25 m heavy (24/32 V systems only)The minimum bends permitted are:Minimum bend, light cable 60 mm (~2.5 in) radiusMinimum bend, heavy cable 82 mm (~3.75 in) radiusRadome scanner cableThe length of the supplied cable should be sufficient to complete the cable runrequired on most small vessels. For longer runs, additional or replacementcables are available, which have 4 power cores to minimise voltage drops overthe longer cable run: these optional cables include 5 m and 10 m extensioncables, and a 25 m replacement cable.The maximum inter-unit cable length is limited by the minimum supplyvoltage, the scanner type (18" radome or 24" radome), and the cable type (2 or 4154_2c1.p65 13/05/99, 13:1711
12 Pathfinder Radar Scannerspower cores): if a mix of light and heavy cables is used, only 2 power cores areconnected through.Note: For vessels with 24 V power systems, any combination of inter-unitcables can be used.For vessels with 12 V power systems, the recommended cable(s) for differentrun lengths are given in the following table, which assumes a minimum supplyvoltage of 10.7 V (the lowest voltage likely to be reached by a 12 V battery innormal marine use).

If youextend the power cable you may need to select different inter-unit cable(s), asdiscussed in the following section Power Cable.Refer to the packing list in Section 1.2 for cable part numbers24 V and 32 V SystemsFor vessels with 24 V and 32 V power systems, any combination of inter-unitcable up to a maximum length of 35 m can be used.Power cable - radome scannersThe radome radar systems are intended for use on ships’ DC power systemsoperating in the 10.7 to 32 V DC range (that is, 12 V and 24 V systems, not 32 Vsystems). A 1.5 m (5 ft) power cable is supplied (with the display unit) forconnecting the ship’s DC power to the radar scanner via the display unit. Referto the HSB Series Display Owner’s Handbook for details on connecting thiscable. This section provides details for extending the length of the power cable.If a longer power cable run is required, use the supplied power cable to connectto the display unit. Then use a suitable connector block to connect the free endto the extension cable. The supplied power cable has a cross-section of2.0 mm2.Note: For vessels with 24 V power systems, the power cable may be extendedby up to 20 m using a wire gauge of 1.5 mm2 (AWG 16) or greater, irrespectiveof the inter-unit cable length.154_2c1.p65 13/05/99, 13:1713
14 Pathfinder Radar ScannersFor vessels with 12 V power systems, longer power cable runs may requirelarger wire gauges to minimise any voltage drop in the cable. The scanner typeand the length and type of the inter-unit cable (see tables) also affect the wiregauge required for the extension power cable. In order to determine the correctsupply cable size if the power cable must be extended, estimate the length ofcable between the ship’s main power source and the connector block, and thenselect the wire size indicated by the distance and inter-unit cable in theappropriate table following.For example, you might have a 24" scanner, with 20 m between the scanner anddisplay unit, that you plan to connect by extending the supplied 15 m heavyinter-unit cable with a 5 m extension cable. In addition, your 12 V power supplymight be 10 m from the display unit, requiring an extension of 8.5 m.

Open array scanners draw considerable power from the vesselspower source, especially in high wind speeds. It is essential for reliableoperation that the unit is supplied with a low resistance power cable system,especially when operated from a 12 V power system.CAUTIONDo not use the 48" Open Array Scanner with an SL70 or Autohelm 7”LCD display unit. Failure to observe this may result in permanent damageto the display unit.12 V systemsExtensions to the supplied power cable must be kept to a minimum and thepower should be fed directly from the output of the battery isolator switch viaits own dedicated cable system. It is recommended that no additional powerswitch is included in this power cable.CAUTIONThe display unit does not include a fuse for scanner power, so an in-linefuse or circuit breaker rated at 20 A MUST be included in the power cable.All power connections must be of high quality to minimise their resistance andto remove the risk of accidental shorts. Recommended maximum power cableextensions are given in the table below. These figures relate to the total cableextension, from the end of the supplied 1.5 m power cable to the system batteryterminals. Do not exceed these lengths as unreliable operation may result.154_2c1.p65 13/05/99, 13:1715
