EMC Installation Guidelines
All Raytheon equipment and accessories are designed to the best industry standards for use in the leisure marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation configuration is essential to maintain EMC performance and CE compliance. 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.
To avoid the risk of operating problems, all Raytheon equipment, and cables connected to it, should be installed as follows:
• Ensuring you follow the installation instructions in Chapter 2, particular with reference to earthing details.
• With at least 1m (3ft) 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 2m (7ft).
• Avoiding the beam from another radar scanner. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.
• The equipment should be supplied from a different battery than the one used for engine start. Voltage drops below 10.7V in the power supply to our products can cause the equipment to reset. This will not damage the equipment, but will cause the loss of some information and can change the mode of operation.
• Genuine Raytheon cables must be used at all times. Cutting and rejoining these cables can compromise EMC performance and must therefore be avoided 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 in the same position. Section 2.1 Installing the Radome Scanner includes instructions on fitting a ferrite.
The following illustration shows a typical range of suppression ferrites fitted to
Raytheon equipment.
154_1c1.p65

Chapter 1: Overview
If your Raytheon equipment is going to be connected to other equipment using a cable not supplied by Raytheon, a suppression ferrite MUST always be fitted to the cable close to the Raytheon unit.
1.2 Unpacking and Inspecting the Components
Unpack your system carefully, to prevent damage to the equipment. It is good practice to save the carton and packing for future use, in case you need to return the unit for service.
Check that you have all the correct system components. These depend on your system package, as follows:

1.3 Selecting the Scanner Unit Site
This section provides information that affects the possible locations of the scanner, 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 of the 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 insulated from 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 practical above the waterline, for two reasons:
- Radar operates at the line-of-sight, so a high mounting position gives better long range performance.
- Surrounding large objects, in the same horizontal plane, can interfere with the radar signal and cause blind areas (shadow sectors) and false targets on the radar screen (see below).
However, do not mount the scanner so high that it is affected by the pitching and rolling of the vessel. In addition, you may need to lower the scanner to avoid creating a shadow sector.
• Access: The scanner unit site should be easily accessible to allow maintenance 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 a magnetic compass.
• Cable run: The maximum length of cable between the display unit and the scanner unit should not normally exceed 20m (60ft) for radome scanners. If you need to use a longer cable, refer to Section 1.4 Cable Runs.
• Shadow sectors and false echoes: Mount the scanner away from large structures or equipment, such as the fly bridge, large engine stacks, searchlights, horns, or masts. It is particularly important to avoid shadow sectors near the bow. Raising or even lowering the scanner may help to reduce these effects.
In shadow areas beyond the obstruction there will be a reduction of the beam intensity, although not necessarily a complete cut-off; there will be a blind sector if the subtended angle is more than a few degrees.
In some shadow sectors the beam intensity may not be sufficient to obtain an echo from a very small object, even at close range, despite the fact that a
4 24/12/98, 08:54
Chapter 1: Overview 5 large vessel can be detected at a much greater range. For this reason the angular width and relative bearing of any shadow sector must be determined at installation. Sometimes shadowing can be seen by increasing the radar gain until noise is present. Dark sectors indicate possible shadowed areas.
This information should be posted near the display unit and operators must be alert for objects in these blind sectors.
It should also be noted that wet sails create shadow areas and thus sail boat operators 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 the radar display. These can be minimised by placing absorbing material, such as a block of wood, between the scanner and mast.
• Platform rigidity/stability: The scanner platform should not twist (causing bearing errors) or be subject to excessive vibration.
• Heat/fumes: Mount the scanner away from the top of exhaust stacks, since the scanner and cables can be damaged by excessive heat and the corrosive effects of stack gases.
Mounting Surface: Sailboats
The scanner unit can be installed on a mast platform, an arch, or a bridge structure. Make sure that the platform surface is flat and the scanner unit drain hole is not obstructed. Raytheon recommends that radome scanner units are best suited for sailboat operation as open array systems are more difficult to protect from ropes and sails.
For sailboat installations, Raytheon offers a universal mast mount kit for each scanner type. These optional mounts are used to fit masts, with a minimum diameter 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 mast aboard the vessel.If there is any doubt concerning the appropriate type of hardware, consult your boat dealer or representative for their recommendations.
Depending on the type of sailboat, a radar scanner guard should be installed if the sails could touch the scanner or platform. Without a proper radar guard the mounting platform and the radar scanner could be severely damaged.
Mounting Surface: Power Boats
On many small vessels the scanner unit can be installed on a mast platform, an arch, or a bridge structure. If necessary, construct a radar mounting pedestal to obtain a sufficiently high mounting position. Make sure that the platform surface is flat and the scanner unit drain hole is not obstructed. Ensure the platform is strong enough to support the maximum shock loads likely to occur.

Chapter 1: Overview
Setting the Radiation Plane
The scanner unit should be mounted so that the array rotates parallel to the waterline. The radar beam is approximately 25° wide in the vertical direction, providing good target detection during the vessel’s pitching and rolling.
7
Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle when the vessel is at its cruising speed. In many cases this substantially alters and raises the radar’s main radiation plane, and can cause poor detection of nearby targets. It may be helpful to lower the radar beam back towards the parallel, by shimming the rear of the radar, so that the beam points slightly downwards with respect to the waterline when the vessel is at rest.
The shims may be made from aluminium plate wedges, simple flat washers, or an angled wooden block. For thick shims, you may need longer securing bolts than the M8x40 bolts supplied with the scanner.

1.4 Cable Runs
You 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 physical damage and exposure to heat - avoid running cables through bilges or doorways, or close to moving or hot objects.
– Acute bends must be avoided
– Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be provided.
You need to run the following cables:
CAUTION
Do not pull the cable through bulkheads using a cord attached to the 8-way connector. This could damage the connections.
• Inter-unit cable, supplied with the scanner unit. This is vinyl-covered and shielded, with a connector plug at one end for connecting to the display unit or extension cable. The other end of the radome scanner cable is fitted with an 8-way plug and power cores (covered by a clear protective sleeve) for connecting to the scanner.
• Power cable, the scanner receives power via the display unit. The power cable is supplied with the display unit. However, connection details are provided in this section.
Inter-Unit Cable - Radome Systems
The inter-unit cable entrance is at the rear of the scanner unit. If the unit is mounted on a hollow mast the cable may be run inside the mast and then fed through the radar’s cable entrance. Make sure that the cable does not chafe where it enters and exits the mast.
Note: Route the cable from the display up to the scanner, since this will require the smallest clearance hole.
CAUTION
The display connector on the inter-unit cable is a moulded plug that cannot be replaced. DO NOT remove this molded plug.
The inter-unit cable, for connecting the scanner to the display unit, depends on your scanner package as follows:

15m heavy (4 power cores)
The minimum bends permitted are:
Minimum bend, light cable
Minimum bend, heavy cable
60 mm (~2.5 in) radius
82 mm (~3.75 in) radius
The length of the supplied cable should be sufficient to complete the cable run required on most small vessels. For longer runs, additional or replacement cables are available, which have 4 power cores to minimise voltage drops over the longer cable run: these optional cables include 5m and 10m extension cables, and a 25m replacement cable.
The maximum inter-unit cable length is limited by the minimum supply voltage, the scanner type (18" radome or 24" radome), and the cable type (2 or 4 power cores): if a mix of light and heavy cables is used, only 2 power cores are connected through.
Note: For vessels with 24V power systems, any combination of inter-unit cables can be used.
For vessels with 12V power systems, the recommended cable(s) for different run lengths are given in the following table, which assumes a minimum supply voltage of 10.7V (the lowest voltage likely to be reached by a 12V battery in normal marine use). Do not use cable combinations that are not included in the table.

Note: This table applies to systems using the standard 1.5m power cable. If you extend the power cable you may need to select different inter-unit cable(s), as discussed in the following section Power Cable.
Note: If you are mounting the scanner on a sailboat, and will need to unstep the mast, you should install a suitable junction box inside the boat. The junction box should provide an 11- or 13-way terminal strip, depending on the number of 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 the length of the un-screened coaxial cores to less than 50mm to maintain EMC conformance.
Power Cable - Radome
The radome radar systems are intended for use on ships’ DC power systems operating in the 10.7 to 32V DC range (that is, 12V and 24V systems, not 32V systems). A 1.5m (5ft) power cable is supplied (with the display unit)for connecting 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 connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable. The supplied power cable has a cross-section of 2.0mm
2 .
Note: For vessels with 24V power systems, the power cable may be extended by up to 20m using a wire gauge of 1.5mm
2 (AWG 16) or greater, irrespective of the inter-unit cable length.
For vessels with 12V power systems, longer power cable runs may require larger wire gauges to minimise any voltage drop in the cable. The scanner type and the length and type of the inter-unit cable (see tables) also affect the wire gauge required for the extension power cable. In order to determine the correct supply cable size if the power cable must be extended, estimate the length of cable between the ship’s main power source and the connector block, and then select the wire size indicated by the distance and inter-unit cable in the appropriate table following.
For example, you might have a 24" scanner, with 20m between the scanner and display unit, that you plan to connect by extending the supplied 15m heavy inter-unit cable with a 5m extension cable. In addition, your 12V power supply might be 10m from the display unit, requiring an extension of 8.5m. To determine the wire gauge required for the power cable extension, refer to the table for the 24” scanner, go to the row labelled “15m Heavy + 5m ext”, and read across until you come to a maximum cable length greater than 8.5m. This is the 10m entry, in the column for 4.0mm
2 wire gauge.

2.1 Radome Scanner
Securing the Radome Scanner to the Mounting Surface
CAUTION
THE DRAIN TUBE MUST ALWAYS BE USED, BUT MAY BE
SHORTENED IF NECESSARY
1. Using the paper template supplied with the scanner mounting kit, mark the flat mounting surface with the mounting holes and drain tube hole, and drill the holes as indicated on the template.
If it is impractical to drill a hole for the drain tube, then the scanner unit should be mounted on 4 suitable spacers 10 mm high and the drain tube length reduced by 10 mm. It will then be clear of the flat surface and can still perform its function.
Note: If you are using a Raytheon mast mount bracket, the surface is preprepared.
Note: If you are mounting the scanner on a flat surface, you may find it easier to fit the drain tube, as described in the following section, before securing the scanner.
2. Position the scanner on the mounting surface, ensuring that the cable inlet is pointing 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 following diagram.

Bitumen washer
Mounting bracket or mounting surface
Greased mounting bolt
D3995-2
You may need to use longer M8 mounting bolts to secure the scanner if you have used shims to lower the main beam.

Connecting the Radome Scanner
CAUTION:
Before wiring the scanner unit, make sure that the inter-unit cable is not connected and power is not applied to the display unit.
When you have run the inter-unit cable to the scanner location, connect the cable as follows:
1. Loosen the 4 (18") or 7 (24") screws securing the scanner cover. These screws are captive and should remain assembled to the lower flange assembly. Press the radome inwards to release the top. This breaks the seal and makes removal easier.
2. To avoid losing the scanner cover, tie the cord, attached to the inside of the base of the scanner, to the eye provided in the cover.
3. If you have a 24" scanner, unscrew and remove the inner cover:

6. Slide the gland nut onto the inter-unit cable (3), and insert the cable, still covered by its protective sleeve, through the gland into the base.
7. Cut and remove the protective sleeve to expose the 8-way plug (4) and power cores (6).
8. If the scanner is connected to an HSB Series Pathfinder Radar display, fit the ferrite clamp (11), supplied loose with the display unit, as follows:
- the ferrite clamp is supplied open. If the clamp has been closed, insert a small, flat-bladed screwdriver into the slots at the end of the clamp opposite the hinge and twist gently.
- Position one-half of the clamp around the eight cores of the inter-unit cable between the 8-way plug (4) and the cable clamp, as close to the 8way plug as possible. (It may be necessary to fit the clamp over the the cable tie closest to the 8-way plug – this will not affect the ferrite clamp’s function).

Ensure that the flat, ferrite side of the clamp does not trap or pinch any of the cables.
Note: on the 24" scanner, the clamp must be contained inside the inner cover.
- With the clamp positioned correctly, close the clamp ensuring none of the cores are trapped by the hinge or latch.
9. Connect the 8-way plug (4) to the connector (5). The correct fitting is with the small arrow marked on the body of the plug facing upwards and to the left hand side. The grey wire will then be at the left hand side and the white wire 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 “+”, and the 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 the black cable leads to the terminal sockets marked “-”, with one lead in each socket.
The terminal clamps (7) are operated using a screwdriver (8), as shown in the inset diagram on the previous page.
CAUTION:
Do not earth the cable screen to the scanner. The radar system is earthed via the display unit.
11. Secure the nut on the watertight gland, making sure that it grips the cable’s outer 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 the thickness 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 the scanner unit so that it cannot foul the rotating antenna.
16. Replace the scanner cover, aligning the mark on the cover with the mark on the scanner base above the cable gland, and tighten the 4 or 7 captive screws. Do not over-tighten these screws.

2.2 System Connections
Power is supplied to the scanner via the display unit; the power cable is supplied with the display unit, refer to your display unit Owner’s Handbook for details on connecting power. However, you should be aware of the following.
Grounding the Radar System
It is important that an effective RF ground is connected to the radar system. You must 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 Systems
The Radome radar system is intended for use on ships’ DC power systems operating in the 10.7 to 32VDC range (12V and 24V systems, not 32V systems). 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 greater than 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-line
6.3A 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’s ground.
The DC system should be either:
• Negative grounded, with the negative battery terminal connected to the ships ground.
• Floating, with neither battery terminal connected to the ships ground.

Chapter 3: Systems Test and Post Installation Alignment 21
Chapter 3:
System Tests and Post Installation Alignment
Once you have installed your radar scanner and display unit, and made all the connections, you need to check your installation. You can then set up the radar system, align the scanner and check the display timing.
Set up, alignment and timing checks are perfomed from the radar system display unit. The procedures are outlined below; full details are provided in the display unit Owner’s Handbook. You should read the Pathfinder radar display unit Owner’s Handbook and familiarise yourself with the operation of the radar.
System Check
Before performing the functional test, check the following:
• All securing bolts are fully tightened and mechanical locking arrangements as specified are in place
• All connections have been made
• All connecting wires are secured and protected as necessary
Note: If you are the boat owner and have performed the installation yourself, ask your authorised installation dealer to check the installation before going to sea.
Set Up, Alignment and Timing Checks
Switch On and Initial Setup
To switch on the display unit, press and hold the POWER key until the unit beeps. The magnetron warm-up sequence should start, after which the unit should enter Standby mode.
If necessary, adjust the lighting and contrast .
If required, change the default language settings
Checking Transmission
WARNING:
The radar scanner transmits electromagnetic energy. Ensure that the scanner has been installed according to the recommendations given in
Chapter 1, and that all personnel are clear of the scanner, before switching to transmit mode.
Run through the radar operations described in the display unit Owner’s
Handbook and check that all the expected data is displayed.

22 Pathfinder Radar Scanners
Bearing Alignment
When the system is correctly installed, you must check the bearing alignment to ensure that targets appear at their correct bearing relative to the ship’s bow, and adjust the alignment if necessary.
Display Timing Adjustment
The display timing can be affected by the length of the cable used to connect the scanner to the display unit. This in turn affects the short range accuracy shown on the display. If you have extended your inter-unit cable, you will need to check the display timing before using the system for navigation.
