Intended Use

The scanner units detailed in this handbook form part of navigational radar
systems intended for light marine use. These radar systems are only an aid to
navigation.

Safety Notices

This radar equipment must be installed and operated in accordance with the
instructions contained in this manual. Failure to do so can result in personal injury
and/or navigational inaccuracies. In particular:

1. High Voltage. The scanner unit contains high voltages. Adjustments require
specialized service procedures and tools only available to qualified service
technicians – there are no user serviceable parts or adjustments. The operator
should never remove the scanner unit internal covers or attempt to service the
equipment.

2. Electromagnetic Energy. The radar scanner transmits electromagnetic
energy. It is important that the radar is turned off whenever personnel are
required to come close to the scanner to perform work on the scanner assembly or
associated equipment.

It is recommended that the radar scanner is mounted out of range of personnel
(above head height).

Do not look directly at the antenna at close range as your eyes are the most
sensitive part of the body to electromagnetic energy.

When properly installed and operated, the use of this radar will conform to the
requirements of ANSI/IEEE C95.1-1992 Standard for Safety Leve ls with Respec t to
Human Exposure to Radio Frequency Electromagnetic Fields, 3 Hz to 300 GHz and
NRPB, Board Statement on Restrictions on Human Exposure to Static and Time
Varying Electromagnetic Fields and Radiation, Doc NRPB, No. 5 (1993).

3. Navigation Aid. This radar unit is only an aid to navigation. Its accuracy can
be affected by many factors, including equipment failure or defects,
environmental conditions, and improper handling or use. It is the user’s

Preface

This handbook describes the following Raymarine Pathfinder radar scanners:

These scanner units may be connected to any HSB/hsb

The open array scanners must not be used with the SL70, SL70
PLUS, SL70RC PLUS or Autohelm 7" LCD Display Unit. This may
result in damage to the display due to the high power
requirements of the open array scanner.

The handbook contains very important information on the installation and
operation of your new equipment. In order to obtain the best results in operation
and performance, please read this handbook thoroughly.

Raymarine’s Technical Support representatives or your local dealer will be
available to answer any questions you may have.

Display Software Version

For full operation of the Pathfinder scanners, the display unit requires an
appropriate software version. For new displays, the correct software version is
normally already installed in the display unit and is fully compatible with the
Pathfinder scanners.

Early display units may not have the correct software and will therefore require
upgrading.
The software version can be confirmed by switching-on the display and checking
the version number during the magnetron warm-up sequence.

Note: If a scanner unit is not connected the version number is only displayed for 10 sec­onds.

Where, necessary Software Upgrade Kits are available from your dealer,
distributor or from Raymarine. We recommend that where a repeater display is
fitted, both the repeater and the master display are upgraded.

C-Series Display Compatibility

To achieve full compatibility with a C-Series Display, your Raymarine radar
scanner may require upgrading. Please refer to the C-Series Display Owner’s
Handbook, or contact Technical Support for details.

The open array scanners cannot be powered from a C-Series display unit; they
must be connected to ship’s power using a split pedestal cable or pedestal
adaptor cable. Full details are provided in this handbook.

Warranty

To register your Pathfinder Radar Scanner ownership, please take a few minutes
to fill out the warranty registration card found at the end of this handbook. It is
very important that you complete the owner information and return the card to
the factory in order to receive full warranty benefits.

The radome scanner package includes a barcode label indicating the serial
number of the unit. This label should be stuck to the warranty registration card.
The open array scanner has two barcode labels indicating the serial numbers of
the pedestal and the antenna units. Both labels should be stuck to the warranty
registration card.

EMC Conformance

All Raymarine equipment and accessories are designed to the best industry
standards for use in the leisure marine environment.

The design and manufacture of Raymarine equipment and accessories confor m to
the appropriate Electromagnetic Compatibility (EMC) standards, but correct
installation is required to ensure that performance is not compromised.

CAUTION:
Do not use an open array scanner with an SL70, SL70 PLUS or
SL70RC PLUS 7" LCD display unit. Failure to observe this may
result in permanent damage to these display units.
The 10 kW open array scanner requires 24 V or higher; it will not
operate on 12 V systems.

This handbook is divided into three chapters as follows:

Chapter One provides information to help you plan the scanner installation. It
includes sections on Unpacking and Inspecting the Components, Selecting the
Scanner Site, Cable Requirements and Power Requirements.

Chapter Two provides detailed instructions on how to mount and connect each
type of scanner.

Chapter Three provides instructions on how to perform the system checks,
alignment and adjustments. It also provides information on maintenance and
what to do if you have problems.

EMC installation guidelines

All Raymarine equipment and accessories are designed to the best industry
standards for use in the leisure marine environment.

Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure that
performance is not compromised. Although every effort has been taken to ensure
that they will perform under all conditions, it is important to understand what
factors could affect the operation of the product.

The guidelines given here describe the conditions for optimum EMC performance,
but it is recognized that it may not be possible to meet all of these conditions in all
situations. To ensure the best possible conditions for EMC performance within the
constraints imposed by any location, always ensure the maximum separation
possible between different items of electrical equipment.

For optimum EMC performance, it is recommended that wherever possible:

• Raymarine equipment and cables connected to it are:

• At least 1 m (3 ft) from any equipment transmitting or cables carrying
radio signals e.g. VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 2 m (7 ft).

• More than 2 m (7 ft) from the path of a radar beam. A radar beam can nor­mally be assumed to spread 20 degrees above and below the radiating
element.

clxxxvii

• The equipment is supplied from a separate battery from that used for engine
start. Voltage drops below 10 V (20 V for 10 kW open array scanners) in the
power supply to our products, and starter motor transients, can cause the
equipment to reset. This will not damage the equipment, but may cause the
loss of some information and may change the operating mode.

• Raymarine specified cables are used at all times. Cutting and rejoining these
cables can compromise EMC performance and so must be avoided unless
doing so is detailed in the installation manual.

• If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation it must be reas­sembled in the same position.
tions on fitting a ferrite.

The following illustration shows a typical range of suppression ferrites fitted to
Raymarine equipment.

includes instruc-

Connections to Other Equipment

If your Raymarine equipment is to be connected to other equipment using a cable
not supplied by Raymarine, a suppression ferrite MUST always be fitted to the
cable close to the Raymarine unit.

2.2 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 detailed in the following tables.

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 minimize potential interference to other systems on board ship (EMC), it
is advisable to mo unt 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 three reasons:

• For safety reasons the scanner should be out of range of personnel, pref­erably above head height. This avoids mechanical danger and electro­magnetic contact, particularly with the eyes.

clxxxix

• 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 or 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 underneath the scanner’s beam.

• Access: The scanner unit site should be easily accessible to allow mainte­nance to be carried out safely.

• Magnetic compass: Mount the scanner unit at least 1 m away from a mag­netic compass.

• Cable run: The maximum length of cable between the display unit and the
scanner unit should not normally exceed 20 m (60 ft) for radome scanners, or
15 m (45 ft) for open array scanners. If you need to use a longer cable power
cable lengths must be considered, refer to
mine appropriate lengths.

• 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
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 targets 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 minimized by placing absorbing material, such as
a block of wood, between the scanner and mast.

• Platform rigidity/stability: The scanner platform should not twist (caus-
ing 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 exhaust gases.

For open array scanners you should also consider the following points:

Section 1.4 Cable Runs

to deter-

cxcii

• Mounting Platform: The platform must be mechanically secure and capa­ble of supporting the mass and inertia of the open array scanner. The com­plete unit weighs: 48" scanner - 30 kg (66.2 lb); 72" scanner - 33.4 kg
(73.7 lb).

• The site must be clear of ropes and moving rigging.

• Sufficient clearance must be allowed to fully open the open array pedestal for
maintenance.

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 (radome scanners) is not obstructed. Raymarine 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, Raymarine offers a universal mast mount kit for each
radome scanner type. This optional mount is used to fit a radome scanner to a flat
surface on a mast with a minimum diameter of 60 mm (2½ in). When using the
mast mount kit, appropriate hardware should be used for the style and structure
of the mast aboard the vessel. Typically, the scanner will be mounted near the first
set of mast spreaders. 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 scann er guar d 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, but take care to follow the scanner site guidelines,
particularly regarding height . If necessary, construct a radar m ounting platform to
obtain a sufficiently high mounting position. Make sure that the platform surface
is flat and the scanner unit drain hole (radome scanners) is not obstructed. Ensure
the platform is strong enough to support the maximum shock loads likely to occur.

cxciii

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.

12.5˚

12.5˚

Waterline

Ideal Radiation Plane

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 de tection 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 radome scanner, or the M10 studding supplied
with the open array scanners.

2.4 Cable Requirements

This section provides details on selecting the appropriate cables for your system.
Permissible cable lengths depend on the scanner type and the boat’s power
system. Information on inter-unit and power cables is provided for both radome
and open array scanners in the following sections.

You need to consider the following before installing the cables:

• You need to connect the scanner to the display unit and to power. The cable
required depends on the display unit and the scanner type as described be low.

• All cables should be adequately clamped 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

• Avoid cutting and re-joining cables (if necessary, refer to the notes below).

Scanner Cables

The cable used to connect your scanner to the display unit and power depends on
the type of scanner and display as follows:

• A radome scanner connected to a Pathfinder or C-Series display requires an
inter-unit cable. The scanner receives power via the display unit, the power
cable is supplied with the display unit but cable details are provided in this
section.

• An open array scanner connected to a Pathfinder display requires an inter-unit
cable. The scanner receives power via the display unit, the power cable is sup­plied with the display unit but cable details are provided in this section.

• An open array scanner cannot be powered from a C-Series Display; it requires
a split pedestal cable which combines the inter-unit and power cores.

• If you are connecting a C-series display to an existing open array scanner unit
with a standard inter-unit cable, you can use the adapator cable instead of the
split pedestal cable; connect the adaptor between the inter-unit cable and the
display.

These cables are illustrated in the following diagram. Cable lengths and part
numbers are listed in

Running the cable to the scanner

CAUTION:
Do not pull the cable through bulkheads using a cord attached to
the connector. This could damage the connections.

The 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:

the smallest clearance hole.

Rejoining cables

You 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 the
cable type - contact Raymarine for details.

• Take care not to damage any of the wires. Make sure that all the wires and, in
particular, the screen are reconnected correctly.

If you are mounting the scanner on the mast of a sailboat, and w ill need to unstep
the mast, you should install a suitable junction box inside the boat.

Route the cable from the display up to the scanner, since this will require

On an open array scanner, the junction box should provide a 13-way terminal strip
with a 20 A rating for power cores. It is essential that all 4 power cores are
connected and that the connection is of very low resistance as considerable
power passes through this connection. Also, you should keep the length of the un­screened coaxial cores to less than 30 mm to maintain EMC conformance.

CAUTION:
The display connector on the scanner cable is a moulded plug that
cannot be replaced. DO NOT remove this moulded plug.

The minimum bends permitted are:

Minimum bend, light cable 60 mm (~2.5 in) radius
Minimum bend, heavy cable 82 mm (~3.75 in) radius

cxcvii

Open array scanner cables for Pathfinder displays

Inter-unit cable

The Pathfinder display inter-unit cables have a connector plug at one end for
connecting to the display unit or extension cable; the other end is prepared ready
to fit to the power and signal connectors (see

Heavy duty cables are available in 15 m and 25 m lengths which should be
sufficient to complete the cable run required on most small vessels. For longer
runs, 5 m and 10 m extension cables are available, both have 4 power cores to
minimize voltage drops over the cable run and incorporate in-line moulded plugs.

The maximum inter-unit cable length is limited by the minimum supply voltage
and the scanner type.

CAUTION:
10 kW scanner systems cannot be used directly with 12 V systems;
they require a 12 V to 24 V converter rated to 180 W. Contact your
authorized Raymarine dealer or distributor for details.

12 V Systems (4 kW scanners only)

For vessels with 12 V power systems, the recommended cable(s) for different run
lengths are given in the following table, which assumes a minimum supply
voltage of 10.7 V (the lowest voltage likely to be reached by a 12 V battery in
normal marine use). Do not use cable combinations that are not

included in the table.

installations should be planned to minimize all cable lengths. Refer to the tables
on page 1-19,

Max. Extension Power Cable Lengths (m) - 10 kW Scanner.

Power cable

The open array scanner systems are intended for use on ships’ DC power systems
operating in the following ranges:

4 kW 10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V systems)
10 kW 20 to 44 V DC range (that is, 24 V and 32 V systems).

CAUTION:
Do not use the open array scanner with an SL70, SL70 PLUS, SL70RC
PLUS or Autohelm 7" LCD display unit. Failure to observe this may
result in permanent damage to the display unit.

10 kW open array scanner systems cannot be used directly with
12 V systems; they require a 12 V to 24 V converter rated to 180 W.
Contact your authorized Raymarine dealer or distributor for
details.

Open array scanners draw considerable power from the vessels power source,
especially in high wind speeds. It is essential for reliable operation that the unit is
supplied with a low resistance power cable system, especially when operated
from a 12 V power system.

12 V systems (4 kW scanners only)

Extensions to the supplied power cable must be kept to a minimum and the power
should be fed directly from the output of the battery isolator switch via its own
dedicated cable system. It is recommended that no additional power switch is
included in this power cable.

CAUTION:
The display unit does not include a fuse for scanner power, so an
in-line fuse or circuit breaker MUST be included in the power
cable.

All power connections must be of high quality to minimize their resistance and to
remove the risk of accidental shorts. Recommended maximum power cable
extensions are given in the table below. These figures relate to the total cable
extension, from the end of the supplied 1.5 m power cable to the system battery
terminals. Do not exceed these lengths as unreliable operation may result.

24 V and 32 V systems

These systems are less sensitive than 12 V systems to voltage loss in the power
cables. However, it is still necessary to use adequate cables to prevent excessive
power loss. The table below gives the recommended wire gauge for different
power cable extension lengths. Raymarine recommends that power is fed directly
from the output of the battery isolator switch via its own dedicated cable system.

Open array scanner cables for C-series displays

A split pedestal cable is required to connect a compatible open array scanner to
the display unit and to the power source.
If you are connecting an existing compatible scanner to a C-Series display a
pedestal adaptor cable can be used instead of the split pedestal cable.

CAUTION:
Do not extend the split pedestal or pedestal adaptor cable.

Split pedestal cable

The split pedestal cable combines the inter-unit and power cores, divided by a
Y junction. One core has a connector plug for connecting to the display unit, the
other core is for connecting to power. The scanner end is prepared ready to fit to
the power and signal connectors (see

Two cable lengths are available:

• 25m cable provides 25m from scanner to Y junction.

• 15m cable provides 15m from scanner to Y junction.
These lengths should be sufficient to complete the cable run required on most

small vessels.

Pedestal adaptor cable

The pedestal adaptor cable combines the inter-unit and power cores, divided by a
Y junction. One core has a connector plug for connecting to the display unit, the
other core is for connecting to power. The scanner end has a connector plug for
fitting to an existing inter-unit cable.

Section 2.2

).

2.5 Power Requirements

Note:

Open array scanners connected to a Pathfinder display and all radome scanners re­ceive power from the display unit via the inter-unit cable. The display power cable is sup­plied with the display unit and details for connecting power are provided in your display
unit Owner’s Handbook. However, you should be aware of the information provided in this
section.

The DC system should be either:

• Negative grounded, with the negative battery terminal connected to the

ship’s ground.

• Floating, with neither battery terminal connected to the ship’s ground.

ccii

CAUTION:
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.

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
cable to the nearest ground point of the ship’s RF ground system. Refer to your
display unit

Owner’s Handbook

for details.

If you need to extend the wire, the extension wire should be an 8 mm braid or
AWG 10 (6.0 mm

2

) multi-stranded cable.

If your vessel does not have an RF system, connect the drain wire to the negative
battery terminal.

Note:

Use only this ground connection.

Power Connections

The power connection to the radar should be made at either the output of the
battery isolator switch, or at a DC power distribution panel. Raymarine
recommends that power is fed directly to the radar via its own dedicated cable
system and MUST be protected by a thermal circuit breaker or fuse, fitted close to
the power connection. Refer to the table below for isolator switch, circuit breaker
or fuse value ratings. Check all terminal connections are clean.

CAUTION:
If you do not have a thermal circuit breaker or fuse in your power
circuit, e.g. fitted to the DC distribution panel, you MUST fit an in­line breaker or fuse to the positive (red) lead of the power cable.

Chapter 3: Installing the Scanner

3.1 Open array scanner

Installation of the open array scanner should only be undertaken by a competent
installer. If you have any difficulty with the installation, please contact your local
Raymarine dealer or distributor.

The open array scanner is supplied in two sections; the pedestal unit and the
antenna. The pedestal unit is secured from below the mounting platform. The
open array is then secured to the pedestal. Full details for mounting the scanner
are given below.

CAUTION:
The pedestal unit has a cap fitted over the open array mounting
shaft to protect the protuding co-axial pin. This cap must be left in
place until the open array is fitted.
The pedestal base is fitted with a seal: DO NOT grease this seal.

WARNING:
The open array scanner weighs: 48" scanner - 30 kg (66.2 lb); 72"
scanner - 33.4 kg (73.7 lb). For safety reasons it is recommended
that the unit is not lifted by one person.
The unit is fitted with lifting eyes (maximum SWL 40 kg) to
facilitate the use of standard lifting accessories, e.g. rope, chain or
strop. The safe working load (SWL) of the lifting accessories
should be 150 kg. Suitable lifting equipment could include a crane,
hoist, or an appropriate rigid, overhead structure.
Alternatively, the unit is suitable for a two person lift. Care must
be taken to ensure that each person is standing on a stable
surface, and that the pedestal is held carefully to ensure it cannot
slip.
The T-bar beneath the open array antenna can be used to aid
lifting.
You should never lift the scanner by holding onto the open array
antenna.

ccviii

Securing the pedestal to the mounting platform

1. Using the paper template supplied with the scanner mounting kit, mark the
flat mounting surface with the holes and drill as indicated on the template.
Refer to

2. Stick the four self-adhesive bitumen washers over the mounting holes.

3. Ensure the lifting eyes are securely fitted to the top of the pedestal, and the
yellow protective cap is in place.

CAUTION:
To prevent damage to the internal mounting bar, ensure the stud
penetration is no more than 32 mm into the pedestal base. We
recommend you mark each stud with tape, 32 mm from one end, to
act as a gauge.

4. Grease the studs with Denso paste (supplied). Using two nuts locked together
on the stud, screw each stud into the pedestal to a maximum of 32 mm, or
until they bottom out. Remove these two nuts.

Note:

studding of a suitable length. Refer to the following illustration for details.

5. Using suitable lifting equipment, raise the pedestal over the mounting sur­face. Carefully lower into position, taking care that the studs pass through the
holes without damaging the threads. Ensure that the cable inlet is pointing
aft.

WARNING:
Support the pedestal unit until it has been secured to the
mounting platform. It is important that all four sets of nuts and
washers are used to secure the pedestal to the mounting
platform.

Section 1.2

If the studding supplied is not long enough, use M10 stainless steel, grade A4-70

when selecting the scanner unit site.

6. Referring to the following illustration, use the four nuts and associated wash­ers supplied to secure the pedestal. Tighten the nuts to 30 Nm (22.1 lb ft.);
ensure the scanner is tightly fitted.
Grease the nuts with Denso paste (supplied).
If required, cut-off any excess stud.

1. Remove the cap from the open array shaft. Retain the cap, it will be required if
the open array is removed from the pedestal.

2. Grease the four securing studs with Denso paste (supplied).

CAUTION:
If the pin is damaged during the following operation you should
contact your service dealer.

3. Lift the open array into position. Carefully lower the array - to prevent damage
to the mounting pin, ensure the array remains parallel to the pedestal so that
the studs slot into the holes on the pedestal mounting bracket.

Note:

The open array mounting bracket is designed so that the array can only be fitted to

the pedestal in the correct orientation.

Chapter 4: Post Installation Checks and

Maintenance

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 timin g. In addition, for a 72" open
array scanner you need to set the antenna size to ensure the scanner rests in the
correct position when rotation stops.

Set up, alignment and timing checks are performed from the radar system display
unit. The procedures are outlined below; full details are provided in the display
unit

Owner’s Handbook

Owner’s Handbook

EMC Conformance

Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.

4.1 System Checks and Alignment

System check

Before performing the functional test, check the following:

. You should read the Pathfinder radar display unit

and familiarize yourself with the operation of the radar.

• 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 a nd have performed the installation you rself, ask your au­thorized installation dealer to check the installation before going to sea

.

Set up, alignment and timing checks

Switch on and initial set up

On the open array scanner, ensure the power switch on the pedestal is set to ON.
To switch on the display unit, press and hold the
The magnetron warm-up sequence should start, after which the unit should enter

Checking transmission

WARNING:
The radar scanner transmits electromagnetic energy. Ensure that
the scanner has been installed according to the recommendations
given in
before switching to transmit mode.

Chapter 1

, and that all personnel are clear of the scanner,

Run through the radar operations described in the display unit
and check that all the expected data is displayed.

Owner’s Handbook

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.
It is advisable to check the display timing before using the system for navigation.

72" open array position alignment

To ensure the 72" open array scanner rests in correct position when rotation
stops, you need to adjust the radar set up as follows:

1. With the display switched on in Radar mode, press MENU then press the
RADAR SET UP soft key.

2. Use the cursor to select the ANTENNA SIZE option, then press the 6 ft soft key.
Press ENTER twice to return to the default display.

If the Radar Set Up menu option ANTENNA SIZE is not available, then you
have an older version of display software. The 72" open array scanner will
operate correctly with this display. However, for details on adjusting the open
array stopping-position, please contact your authorized Raymarine dealer or
distributor.

ccxxv

4.2 Maintenance

Warnings

The display unit and scanner unit contain
Adjustments require specialized service procedures and tools
only available to qualified service technicians - there are no user
serviceable parts or adjustments and the operator should not
attempt to service the equipment. The operator should not
remove the rear cover of the display or any internal covers in the
scanner.

Always turn the radar system off before carrying out any routine
maintenance on the scanner or nearby equipment. Switch off the
display unit before removing the power cord.

Routine Checks

The radar scanners are sealed units. Maintenance procedures are therefore
limited to the following periodical checks:

• Examine the cables for signs of damage, such as chafing, cuts or nicks.

• Check that the cable connectors are firmly attached.

• Make sure the scanner and pedestal are still attached securely to the mount­ing.

• Once a year, remove, grease and re-attach the mounting bolts securing the
scanner and pedestal.

.

Servicing and Safety

• Raymarine equipment should be serviced only by authorized Raymarine ser­vice technicians. They will ensure that service procedures and replacement
parts used will not affect performance. There are no user serviceable parts in
any Raymarine product.

• Some products generate high voltages, so never handle the cables/connec­tors when power is being supplied to the equipment.

• When powered, all electrical equipment produces electromagnetic fields.
These can cause adjacent pieces of electrical equipment to interact with one
another, with a consequent adverse effect on operation. In order to minimize
these effects and enable you to get the best possible performance from your
Raymarine equipment, guidelines are given in the installation instructions, to

ccxxvi

enable you to ensure minimum interaction between different items of equip­ment, i.e. ensure optimum Electromagnetic Compatibility (EMC).

• Always report any EMC-related problem to your nearest Raymarine dealer.
We use such information to improve our quality standards.

• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but it can lead to spurious resetting action, or momentarily may
result in faulty operation.

4.3 Problem Solving

All Raymarine products are subjected to comprehensive test and quality
assurance programmes prior to packing and shipping. However, if this unit should
develop a fault, please refer to the following table to identify the most likely cause
and the corrective action required to restore normal operation.

If you still have a problem after referring to the table below, contact your local
dealer, national distributor or Raymarine Product Support Department for further
advice.

Always quote the product serial numbers. The display unit serial number is printed
on the back of the unit, and the scanner serial number is on the back of the
scanner near the gland.
