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, particularwith reference to earthing details.• With at least 1m (3ft) 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 2m (7ft).• 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 10.7V 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 compromise EMC performance and must therefore beavoided unless 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_1c1.p65 24/12/98, 08:542
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.

4Pathfinder Radar Scanners1.3 Selecting the Scanner Unit SiteThis section provides information that affects the possible locations of thescanner, and its position relative to the display unit and to the power supply.The dimensions of the each scanner unit are shown in the following diagrams.Selecting 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 board ship(EMC), it is advisable to mount the scanner on a part of the boat that is insulatedfrom the ship’s battery negative. If you cannot do this, and encounter problems,you can fit insulating bushes between the scanner and its mounting bracket.•Height: The scanner unit should normally be mounted as high as practicalabove the waterline, for two reasons:- 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 (shadow sectors) and false targets onthe 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.•Safety: The scanner should be out of range of personnel (above head height).•Magnetic compass: Mount the display unit at least 1m away from amagnetic compass.•Cable run: The maximum length of cable between the display unit and thescanner unit should not normally exceed 20m (60ft) for radome scanners. Ifyou need to use a longer cable, 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 a154_1c1.p65 24/12/98, 08:544
Chapter 1: Overview 5large vessel can be detected at a much greater range. For this reason theangular 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 objects 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 stack gases.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 is not obstructed. Raytheon recommends that radome scanner units arebest suited for sailboat operation as open array systems are more difficult toprotect from ropes and sails.For sailboat installations, Raytheon offers a universal mast mount kit for eachscanner type. These optional mounts are used to fit masts, with a minimumdiameter of 60 mm (2½in), to a flat surface. When using the mast mount kit,appropriate hardware should be used for the style and structure of the mastaboard the vessel.If there is any doubt concerning the appropriate type ofhardware, consult your boat dealer or representative for their 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.Mounting Surface: Power BoatsOn many small vessels the scanner unit can be installed on a mast platform, anarch, or a bridge structure. If necessary, construct a radar mounting pedestal toobtain a sufficiently high mounting position. Make sure that the platformsurface is flat and the scanner unit drain hole is not obstructed. Ensure theplatform is strong enough to support the maximum shock loads likely to occur.154_1c1.p65 24/12/98, 08:545

Chapter 1: Overview 7Setting 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 scanner.154_1c1.p65 24/12/98, 08:547
8Pathfinder 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 cleated 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 provided.You need to run the following cables:CAUTIONDo not pull the cable through bulkheads using a cord attached to the 8-wayconnector. This could damage the connections.•Inter-unit cable, supplied with the scanner unit. This is vinyl-covered andshielded, with a connector plug at one end for connecting to the display unitor extension cable. The other end of the radome scanner cable is fitted withan 8-way plug and power cores (covered by a clear protective sleeve) forconnecting to the scanner.• Power cable, the scanner receives power via the display unit. The powercable is supplied with the display unit. However, connection details areprovided in this section.Inter-Unit Cable - Radome SystemsThe 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 molded plug.The inter-unit cable, for connecting the scanner to the display unit, depends onyour scanner package as follows:154_1c1.p65 24/12/98, 08:548

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 5m and 10m extensioncables, and a 25m 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 4power cores): if a mix of light and heavy cables is used, only 2 power cores areconnected through.Note: For vessels with 24V power systems, any combination of inter-unitcables can be used.For vessels with 12V power systems, the recommended cable(s) for differentrun lengths are given in the following table, which assumes a minimum supplyvoltage of 10.7V (the lowest voltage likely to be reached by a 12V battery innormal marine use). Do not use cable combinations that are not included inthe table.Recommended Radome Inter-Unit Cable(s) for Vessels with 12V PowerSystemsInter-Unit Cable Scanner PackageLength Required (m) 2D (US) 2DE (Eur) 4D10 Std 10m light N/A N/A15 Std + 5m ext Std 15m light Std 15m heavy20 Std + 10m ext 25m assembly Std + 5m ext25 25m assembly 25m assembly Std + 10m ext30 25m + 5m ext 25m + 5m ext 25m + 5m ext35 25m + 10m ext 25m + 10m ext 25m + 10m extRefer to the packing list in Section 1.2 for cable part numbers154_1c1.p65 24/12/98, 08:549
10 Pathfinder Radar ScannersNote: This table applies to systems using the standard 1.5m power cable. If youextend the power cable you may need to select different inter-unit cable(s), asdiscussed in the following section Power Cable.Note: If you are mounting the scanner on a sailboat, and will need to unstep themast, you should install a suitable junction box inside the boat. The junctionbox should provide an 11- or 13-way terminal strip, depending on the numberof power cores in your cable, with a 10A rating. If cutting and joining the cable,be careful not to damage any of the wires, and make sure that all the wires and,in particular, the screen are re-connected correctly. Also, you should keep thelength of the un-screened coaxial cores to less than 50mm to maintain EMCconformance.Power Cable - RadomeThe radome radar systems are intended for use on ships’ DC power systemsoperating in the 10.7 to 32V DC range (that is, 12V and 24V systems, not 32Vsystems). A 1.5m (5ft) power cable is supplied (with the display unit)forconnecting the ship’s DC power to the radar scanner via the display unit.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 of 2.0mm2.Note: For vessels with 24V power systems, the power cable may be extendedby up to 20m using a wire gauge of 1.5mm2 (AWG 16) or greater, irrespectiveof the inter-unit cable length.For vessels with 12V 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 20m between the scanner anddisplay unit, that you plan to connect by extending the supplied 15m heavyinter-unit cable with a 5m extension cable. In addition, your 12V power supplymight be 10m from the display unit, requiring an extension of 8.5m. Todetermine the wire gauge required for the power cable extension, refer to thetable for the 24” scanner, go to the row labelled “15m Heavy + 5m ext”, andread across until you come to a maximum cable length greater than 8.5m. Thisis the 10m entry, in the column for 4.0mm2 wire gauge.154_1c1.p65 24/12/98, 08:5410

Using the paper template supplied with the scanner mounting kit, mark theflat mounting surface with the mounting holes and drain tube hole, and drillthe holes as indicated on the template.If it is impractical to drill a hole for the drain tube, then the scanner unitshould be mounted on 4 suitable spacers 10 mm high and the drain tubelength reduced by 10 mm. It will then be clear of the flat surface and canstill perform its function.Note: If you are using a Raytheon mast mount bracket, the surface is pre-prepared.Note: If you are mounting the scanner on a flat surface, you may find iteasier to fit the drain tube, as described in the following section, beforesecuring the scanner.2. Position the scanner on the mounting surface, ensuring that the cable inlet ispointing aft.3. Locate the bolts and washers supplied with the scanner, grease the bolts,and secure the scanner to the mounting surface as shown in the followingdiagram.Scanner baseMounting bracketor mounting surfaceGreased mounting boltD3995-2Bitumen washerYou may need to use longer M8 mounting bolts to secure the scanner if youhave used shims to lower the main beam.154_1c2.p65 24/12/98, 08:5513
14 Pathfinder Radar ScannersConnecting the Radome ScannerCAUTION:Before wiring the scanner unit, make sure that the inter-unit cable is notconnected and power is not applied to the display unit.When you have run the inter-unit cable to the scanner location, connect thecable as follows:1. Loosen the 4 (18") or 7 (24") screws securing the scanner cover. Thesescrews are captive and should remain assembled to the lower flangeassembly. Press the radome inwards to release the top. This breaks the sealand makes removal easier.2. To avoid losing the scanner cover, tie the cord, attached to the inside of thebase of the scanner, to the eye provided in the cover.3. If you have a 24" scanner, unscrew and remove the inner cover:D4006-1Inner cover4. Remove the drain tube from inside the base of the scanner, and insert it intothe drain hole as shown in the following diagram. Pull the tube gently fromoutside the scanner so that it clips into place.154_1c2.p65 24/12/98, 08:5514

Slide the gland nut onto the inter-unit cable (3), and insert the cable, stillcovered by its protective sleeve, through the gland into the base.7. Cut and remove the protective sleeve to expose the 8-way plug (4) andpower cores (6).8. If the scanner is connected to an HSB Series Pathfinder Radar display, fitthe ferrite clamp (11), supplied loose with the display unit, as follows:- the ferrite clamp is supplied open. If the clamp has been closed, insert asmall, flat-bladed screwdriver into the slots at the end of the clampopposite the hinge and twist gently.- Position one-half of the clamp around the eight cores of the inter-unitcable between the 8-way plug (4) and the cable clamp, as close to the 8-way plug as possible. (It may be necessary to fit the clamp over the thecable tie closest to the 8-way plug – this will not affect the ferriteclamp’s function).154_1c2.p65 24/12/98, 08:5515
16 Pathfinder Radar ScannersEnsure that the flat, ferrite side of the clamp does not trap or pinch anyof the cables.Note: on the 24" scanner, the clamp must be contained inside the innercover.- With the clamp positioned correctly, close the clamp ensuring none ofthe cores are trapped by the hinge or latch.9. Connect the 8-way plug (4) to the connector (5). The correct fitting is withthe small arrow marked on the body of the plug facing upwards and to theleft hand side. The grey wire will then be at the left hand side and the whitewire will be at the right hand side.10. Connect the red and black power cores (6).If you have a 10m or light 15m inter-unit cable, there is one pair of cores.Connect the red cable lead to one of the terminal sockets marked “+”, andthe black cable lead to one of the sockets marked “-”.If you have a heavy 15m inter-unit cable, there are two pairs of cores.Connect the red cable leads to the terminal sockets marked “+”, and theblack cable leads to the terminal sockets marked “-”, with one lead in eachsocket.The terminal clamps (7) are operated using a screwdriver (8), as shown inthe inset diagram on the previous page.CAUTION:Do not earth the cable screen to the scanner. The radar system is earthedvia the display unit.11. Secure the nut on the watertight gland, making sure that it grips the cable’souter sheath.12. Secure the cable with the cable clamp (9), using the two screws (10)provided. The clamp can be installed either way up, depending on thethickness of the cable: use the position that matches the profile of the cable.13. Tighten the securing nut (1) again to ensure a waterproof seal.14. If you have a 4D scanner, replace the inner cover over the connectors.15. Untie the cord from the scanner cover, and coil it up in the base of thescanner unit so that it cannot foul the rotating antenna.16.

Chapter 2: Installing the Scanner 172.2 System ConnectionsPower is supplied to the scanner via the display unit; the power cable is suppliedwith the display unit, refer to your display unit Owner’s Handbook for detailson connecting power. However, you should be aware of the following.Grounding the Radar SystemIt is important that an effective RF ground is connected to the radar system. Youmust ground the radar by connecting the drain wire (screen) of the Power/NMEA Input cable to the nearest ground point of the ship’s RF ground system.Refer to your Display Unit Owner’s Handbook for details.Note: Use only this ground connection.DC Power Connection - Radome SystemsThe Radome radar system is intended for use on ships’ DC power systemsoperating in the 10.7 to 32VDC range (12V and 24V systems, not 32Vsystems). The connections should be made at a DC power distribution panel,through an isolation switch or circuit breaker that is fused or trips at not greaterthan 10A. Check that all connection terminals are clean.CAUTION:If you do not have a breaker in your power circuit, you must fit an in-line6.3A quick-blow fuse to the positive (red) lead of the power cable.This radar is not intended for use on “positive” ground vessels.The power cable Earth screen connections must be connected to the ship’sground.The DC system should be either:• Negative grounded, with the negative battery terminal connected to the shipsground.• Floating, with neither battery terminal connected to the ships ground.154_1c2.p65 24/12/98, 08:5517
18 Pathfinder Radar ScannersScanner ConnectionThe inter-unit cable is connected to the scanner as described in Section 2.1. Ifyou are using an inter-unit extension cable, connect this to the display unit, andconnect the supplied cable to the extension cable.The scanner connector pins are shown in the following diagram, together withthe connections and core colours .CAUTIONThe display connector on the inter-unit cable is a moulded plug thatcannot be replaced. DO NOT remove this molded plug.1235 47101186913 12WhiteBlackOrangeBlackBlackGreenYellowShieldRedRedVioletBlueGreyVideoVideo RTN*Battery --veTx Trigger +Battery --veData I/O +Tx Trigger -- Battery +veData I/O --*Battery +veAzimuth +Azimuth -- 1234567 8910111213WhiteBlackOrangeYellowGreenBlueViolet GreyRedRedBlackBlack 8765432 1VideoVideo RtnTx Trigger +Tx Trigger --Data I/O +Data I/O --Azimuth + Azimuth --Battery +ve*Battery +ve*Battery --veBattery --ve D4290-1Front view ofDisplay Cable Connector Front view ofScanner Cable Connector2 14 36 58 7Display Scanner* Not present on 'light', 11 core cables.

Chapter 3: Systems Test and Post Installation Alignment 21Chapter 3:System Tests and Post Installation AlignmentOnce you have installed your radar scanner and display unit, and made all theconnections, you need to check your installation. You can then set up the radarsystem, align the scanner and check the display timing.Set up, alignment and timing checks are perfomed from the radar systemdisplay unit. The procedures are outlined below; full details are provided in thedisplay unit Owner’s Handbook. You should read the Pathfinder radar displayunit Owner’s Handbook and familiarise yourself with the operation of theradar.System CheckBefore performing the functional test, check the following:• All securing bolts are fully tightened and mechanical locking arrangementsas specified are in place• All connections have been made• All connecting wires are secured and protected as necessaryNote: If you are the boat owner and have performed the installation yourself,ask your authorised installation dealer to check the installation before going tosea.Set Up, Alignment and Timing ChecksSwitch On and Initial SetupTo switch on the display unit, press and hold the POWER key until the unitbeeps. The magnetron warm-up sequence should start, after which the unitshould enter Standby mode.If necessary, adjust the lighting and contrast .If required, change the default language settingsChecking TransmissionWARNING:The radar scanner transmits electromagnetic energy. Ensure that thescanner has been installed according to the recommendations given inChapter 1, and that all personnel are clear of the scanner, before switchingto transmit mode.Run through the radar operations described in the display unit Owner’sHandbook and check that all the expected data is displayed.154_1c3.p65 24/12/98, 08:5521
22 Pathfinder Radar ScannersBearing AlignmentWhen the system is correctly installed, you must check the bearing alignment toensure that targets appear at their correct bearing relative to the ship’s bow, andadjust the alignment if necessary.Display Timing AdjustmentThe display timing can be affected by the length of the cable used to connect thescanner to the display unit. This in turn affects the short range accuracy shownon the display. If you have extended your inter-unit cable, you will need tocheck the display timing before using the system for navigation.154_1c3.p65 24/12/98, 08:5522
