Chapter 1 OVERVIEW

The proper installation of the radar equipment is critical in ensuing its effective and

reliable performance as well as facilitating maintenance and repair. Carefully install the

radar equipment by following the procedures below.

 Install the scanner as high as possible while taking the scanner's weight into

consideration.

 It is preferable to install the display unit in the wheel house to facilitate observations.

 Available cable lengths and types for installing the radar JMA-3300 are as shown in

the table below. Request an appropriate cable from JRC beforehand. A cable

longer than the sufficient length may degrade radar performance, so give it careful

consideration when planning the installation.

2.1 SELECTING THE INSTALLATION POSITION

 Physical Selection Criteria

 Install the scanner at the center of the mast on the keel line.

 If the scanner cannot be installed at the above position for some reason, the amount

of deviation must be minimized. And, reinforce the mount base and the platform and

take precautions to protect the scanner from vibration and impact at the installation

position.

 To avoid the radiating section coming in contact with other installed objects while it

is rotating, ensure that there is at least 200 millimeters from the swing circle (turning

radius) to other installed objects (Fig. 2.1-1). The swing circle of the JMA-3300

radar's scanner is as shown in Table 2.1-1.

 Both side covers of the operating section are opened for maintenance. Therefore,

install it 200 mm or more away from the other objects.

 Avoid having a rope or signal flag from winding around the radiating

section thereby preventing it from rotating.

 Avoid the effects of dust and heat caused by smoke from a chimney.

 When determining the appropriate scanner height and installation

location, take into consideration the reduction of vibration, the strength

of the hull and the scanner mount base, and maintenance properties.

 Provide for maintenance space: platform, safety link, hand rail, steps,

etc.

 Electrical selection criteria

 The installation height of the scanner relates to the maximum detection distance. The

higher, the better. However, if it is too high, radio wave energy greatly attenuates

above the scanner's vertical beam width (the point -3 dB from the peak of the main

lobe). As a result, it is difficult to detect a close-in target. Sea clutter also increases.

Determine the installation height by taking into consideration the weight, maximum

length of the cable, and maintenance after installation. If the installation height of the

scanner is low, it is difficult to detect a long distance target. The ship's mast, derrick,

and chimney interfere with radiating beam causing the range that cannot be viewed

on the radar display to increase.

Generally, the lowest scanner installation position is supposed to be on the A-B line

shown in Fig. 2.1-1. In the case of the JMA-3300 type radar, 2 equals 20°.

Specifically, the scanner position is normally elevated so that the chimney and the

2-2

shrine-gate type mast do not interfere with radiating beam.

Chapter 2 INSTALLATION OF THE SCANNER

2.1 SELECTING THE INSTALLATION POSITION

Fig. 2.1-2 Lowest scanner installation height

JMA-3300: =10°

 If it is considered that sufficient installation height cannot be provided when the

scanner is installed directly on the roof of the wheelhouse, use a mounting rack or

radar mast (Fig. 2.1-3). Normally, when the scanner installation height is less than 2

meters from the roof of the wheelhouse, provide a mounting rack assembled at an

angle frame to install the scanner. When the scanner installation height is 2 m or

higher from the roof of the wheelhouse, provide a cylindrical radar mast to install the

scanner. Consider the convenience of the service staff who take care of installation,

maintenance, adjustment, and repair of the scanner by providing adequate footholds

to the mounting rack and the radar mast.

Fig. 2.1-3 Mounting rack and mast for the scanner

 When installing the scanner, select a location where there are the fewest structural

objects in the surrounding area so that false images which interfere with target

detection will not be generated by signal reflection from other scanners, deck

structures, and cargo. Only as a guide, note that structural objects should not exist

within the range of the vertical beam width (Fig. 2.1-4).

2.1 SELECTING THE INSTALLATION POSITION

Fig. 2.1-4 Scanner and the surrounding structural objects

Vertical beam width of X-band: Approx. 20° (+/-10.0° when the height of the

radiating section is 0°)

When installing two scanners, provide a height difference so that those two scanners do

not enter each other's vertical beam width range.

To avoid interference with other equipment and to prevent radio noise from generating,

do not place the VHF antenna, GPS antenna, and INMARSAT's dome within the range

of the vertical beam width. Keep a record of installation height data. The data is

necessary for the initial setting of the display unit.

 Minimize the blind sector, and ensure the adequate view angle so that the blind

sector does not exist in the range 22.5° from side to rear (Fig. 2.1-5). Specifically,

ensure a sufficient view field in the straight front (relative bearing 000°).

2-4

Fig. 2.1-5 Ensuring view angle

 Magnetron which has strong magnetic force is included in the scanner. Install the

scanner at least 3 meters away from nautical instruments including magnetic

compasses and chronometers.

Chapter 2 INSTALLATION OF THE SCANNER

2.1 SELECTING THE INSTALLATION POSITION

Reference:

 Because most radio wave absorbers have poor durability, some must be replaced

every year.

When installing a reflector, the area to the rear of the reflector becomes a blind sector.

Therefore, minimize the size of the reflector.

 The above procedures for selecting an scanner installation position are described

based on the radar's scanner. Comprehensively select the scanner position by

considering other scanners' installation procedure manual, hull's structure, strength of

the selected position, and vibration.

* If there is a concern that structural objects existing within the vertical beam width

may generate false images, equip the structural objects with a radio wave absorber.

2

(There are two types of absorbers: broadband type having no specific resonant

frequency and narrowband type which can absorb a band with a specific frequency.

Use those where applicable.) Furthermore, it is effective to install a metal reflector,

which reflects radio waves upwardly, between the scanner and a structural object so

that the radar's radio wave will not directly come in contact with the structural object.

NSTALLATION MANUAL

 Confirmation during test run

If the scanner vibrates a lot during test run, try to reduce or prevent vibration by

reinforcing the scanner mount base or using wire stays attached to the radar mast.

 All installations should facilitate protection of equipment, including cabling, from

damage.

 The cables should be kept as short as possible to minimize attenuation of the signal.

 Crossing of cables should be done at right angles(90°) to minimize magnetic field

coupling.

 Install the radar cable as far as from the cables of other radio equipment in order to

prevent other radio equipment from interfering with the radar operations. Especially

inter-wiring cables between scanner unit and display unit of the radar should not be

run parallel with the cables of other radio equipment.

 Cable should not be exposed sharp bends.

 Ensure that the equipment is grounded.

 After installation

After you have completed the installation work, make a installation report with your

signature and explain it to the customer.

Then request him to keep the report on board a ship.

The installation report is now available for download on the our Marine Service

Department website (https://www2.msd.jp/).

Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body. When it is necessary to get
close to the antenna for maintenance or inspection purposes,
make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body.

When conducting maintenance work, make sure to turn off the
power and unplug the power connector J1 of the display unit so
that the power supply to the equipment is completely cut off.
Some equipment components can carry electrical current even
after the power switch is turned off, and conducting maintenance
work without unplugging the power connector may result in
electrocution, equipment failure, or accidents.

 Precautions for transporting and storing the scanner

 A scanner is a heavy load. Be very careful about handling it.

 Do not allow the scanner fall on its side while it is stored or being installed.

 Do not apply rope to the scanner in the way that squeezes or deforms the radiating

section.

 When hoisting the scanner by a crane, do not hoist it by attaching a belt or a rope

only to the scanner's radiating section as shown in Fig. 2.2-1.

 When lifting the X-band scanner (Fig. 2.2-2) :

Wrap a cloth around the scanner's support section located at the bottom of the

radiator, and then attach a belt to it to lift the scanner.

2.2 INSTALLATION PROCEDURE

Fig. 2.2-1 Improper way to hoist

Fig. 2.2-2 X-band

 Installation Procedure

 Maintain a flat level surface on which to install the scanner.

 Use sufficiently thick steel material and reinforcement material for the scanner's

installation surface (mount base) to reduce vibration and impact. Keep the mount

base flat and smooth.

 If there is a partial gap between the mount base and the scanner chassis's legs, work

on the installation surface so that it becomes flat and smooth, or make adjustments

by inserting metal shims.

If a gap exists and the scanner is tightly clamped, the chassis will distort and become

damaged by vibration.

 Avoid using vibration-proof rubber and resin

 Do not insert an elastic body, such as vibration-proof rubber or resin, between the

mount base and the scanner chassis' legs. If rubber or resin is inserted, the amplitude

of vibration increases, resulting in the possibility of damage to the scanner.

Wrap a cloth

2-8

Furthermore, if installation bolts become loose due to deterioration of rubber or resin,

the scanner may be damaged or fall from its mount.

Chapter 2 INSTALLATION OF THE SCANNER

2.2 INSTALLATION PROCEDURE

 Installation and clamping method

 Installation direction

Installation should be done so that the cable gland is oriented toward the stern.

 Bolts, nuts and tightening torque to be used

 Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using

double nuts for each bolt so that the scanner will not become loose (Table 2.2-1).

 Although the length of the bolt will differ according to the thickness of the mount

base, use a bolt long enough so that more than 4 millimeters of thread protrudes

beyond the double nuts after the double nuts have been tightened.

Table 2.2-1 Length of scanner mounting bolts and tightening torque

Thickness of Mount Base Bolt Torque (N-m)

X band 12 M10×55 (mm) SUS304 40

 Use of washer and corrosion-resistant measures

 At the location where a bolt's head or nut comes in contact with the scanner chassis'

legs and the mount base, insert a plain washer which fits the bolt; and, at the location

where the nut comes in contact with the plain washer, insert a spring washer, and

then securely tighten the nuts (Fig. 2.2-3).

 To prevent corrosion due to the contacts between different metals, such as the

scanner chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and

nuts with sealant (Fig. 2.2-3).

 Grounding and corrosion-resistant measures

 Do not install the scanner in place where puddles are often formed.

 Ground the scanner chassis and the installation surface (hull) by using an earth line.

Apply sealant to the connection portion of the earth line to prevent corrosion and

damage by vibration (Fig. 2.2-4).

CAUTION

When you directly connect with the ship's power supply without
using the optional rectifier, measure the voltage between the hull's
earth and the positive side of ship's power supply, and the hull's
earth and the negative side of this. And check voltage of 50 volts
or more is not required.
If voltage of 50 volts or more is required, take the measures which
do not require 50 volts or more between the above mentioned
terminals.
Connection without taking the measures causes system failure or
accident.

 Connecting the cable to the display unit

Connect the CFQ-5436 connector to the connector for which "POWER" is engraved at

the rear of the display unit cabinet.

Turn the plug attached to the connector until it cannot be turned any further.

3.3 INSTALLATION OF THE POWER CABLE (CFQ-5436)

 Selecting a cable when a long power cable is required

The input voltage to the display unit is determined by subtracting the voltage drop up to

the power cable from the ship's power supply voltage. Therefore, if the power cable is

too thin or too long, the voltage drops substantially, preventing the radar from

functioning at its full capacity. Use the following guideline for selecting a power cable.

 Take the voltage fluctuation rate into consideration when determining a voltage (Vs)

value of the ship's power supply.

 Use the following formula for calculating a voltage drop (V).

V=2LRKI

L: Cable length

R: Direct current resistance at 20°C (/m)

3.11 CONNECTING CONTACT SIGNALS TO

EXTERNAL BUZZERS/EXTERNAL DEVICES

This equipment has the dry contact output that outputs external buzzer and alarm status

as contact signals.

Dry contacts are output from pins 6 and 7 of the 8-pin connector of J5.

Reference:

The capacity of the output contacts is up to 1A/30V.

When a larger current/voltage is applied, install an external device with a sufficient contact

capacity such as a relay.

When the current/voltage exceeded the contact capacity, the contact of this equipment is

fused and external buzzer is emitted continuously, causing an extremely dangerous

condition.

 Connecting contact signals to external buzzers/external devices

When connecting an external buzzer to this radar, connect the necessary signal line to the

attached NMEA data connector P5 (for J5) using the following diagram as the reference.
