High voltage safety warning

Precautionary measures

The voltages used to power this equipment
are potentially lethal. Even 110 volts can kill.
Whenever possible, the following
precautionary measures must be taken before
any work is carried out inside the equipment:

S Switch off all high-voltage power supplies.
S Check the operation of any door interlocks

and any other safety devices.

S Completely discharge all high-voltage

capacitors.

It should be noted that interlocks and safety
devices are normally located only at regular
access points, and high voltages may be
exposed during dismantling.

Never work alone on high-voltage
equipment!

First aid in the event of
electric shock

Normally, even a high voltage electric shock
will not kill instantly. The victim can still be
revived even when his breathing and
heart-beat have ceased.

Could YOU save someone’s life?
In the event of electric shock, the correct

actions, performed quickly may well save the
victim’s life. Make sure you know what to
do!

Immediate action

While shouting for help, remove the source of
power from the victim. Switch off the supply
if possible, or using a dry, non-conductive
material (rubber gloves, broom handle etc.) to
insulate yourself, separate the victim from the
source. If the voltage exceeds 1000 volts,
switch off the supply and be ready to catch
the victim. Take care- do not become a victim
yourself.

Commence first aid on the spot. Continue to
shout for assistance till someone arrives.

1 Lay the victim flat on his back and loosen

any tight clothing (collar, tie, belt etc.).

2 Open his mouth and check for and remove

any false teeth, chewing gum etc.

3 Check if the victim is breathing. If not,

check if his heart is beating. The pulse is
normally easily found in the main arteries
of the neck, either side of the throat, up
under the chin.

If his heart is beating but he is not breathing,
commence artificial respiration. If the
victim’s heart is not beating, commence
external cardiac massage (ECM). Continue to
shout for assistance till someone arrives.

External cardiac massage

1 Kneel beside the victim. Place the heel of

one hand in the centre of his chest, at a
position half way between the notch
between the collar-bones at the top of his
chest, and the dip i n the breast-bone at the
base of his rib cage. Place the other hand
on top of the first.

2 Keeping the arms straight and using your

entire weight, press down rapidly so that
the breast bone is depressed four- five cm,
then release the pressure. Repeat
rhythmically at a rate of one cycle per
second. This will be hard work, but keep
going. His life depends on YOU. Do not
worry about breaking his ribs - these will
heal if he survives.

851-160085 / B

Artificial respiration

1 Kneel besides the victim’s head. Place one

hand under his neck and lift, allowing his
head to fall back. This will lift his tongue
and open the air passage in his throat.

2 Place the palm of the hand on his forehead

to maintain the ”chin-up” position.

3 Using the index finger and thumb of the

same hand, pinch the victim’s nostrils
closed. Open his mouth.

4 Take a deep breath and cover his mouth

with yours. Blow steadily into his lungs to
expand his chest. Remove your mouth
from his to allow the air t o escape from his
chest. You should be able to see his chest
deflate.

5 Repeat the ”inflation-deflation” cycle at a

rate of about 12 cycles per minute till the
victim begins to breath normally again.

Combining ECM and artificial
respiration

If you are alone, perform one cycle of
artificial respiration for every five cycles of
ECM. This will be hard work, but keep going.
His life depends on you!

If there are other people available to help, one
should perform the ECM while one performs
the artificial respiration for every five cycles
of ECM. It will be much more efficient with
two people.

Once the victim’s heart is beating and he is
breathing, roll him onto his side and support
him in that position. As consciousness returns
he may vomit, and this will allow any liquid
to drain out of his mouth.

Remove the victim to a hospital as soon as
possible, but do not interrupt the artificial
respiration and ECM cycles till his heart beat
and breathing returns.

If started quickly and performed correctly, the
resuscitation methods described will keep a
sufficient volume of oxygenated blood
flowing trough the victims body to allow full
recovery.

Proficiency i n the resuscitation methods can
only be achieved trough training. All
personnel concerned should attend courses on
a regular basis. Remember, someone’s life
could depend on you.

Do you know what to do?

1 INSTALLATION DOCUMENT

This installation manual will act as an installation document for
later updating and service on the sonar, and must therefore be
stored on board the vessel into which the equipment is to be
installed.

To ensure the best possible result of the installation, it is important
that each procedure is carefully followed. Each listed procedure
comprises squares for t icking off while proceeding in the
procedure. In addition to be a sign that the procedure is followed,
this will also be a good guidance for the installer.

Note that the installer becomes fully responsible for the
equipment during the installation, and that the guarantee only is
covered when the installation is made in full accordance with this
installation manual.

2 SUPPLY CONDITIONS

2.1 General

This manual describes the installation for both the SD 570 and the
SE 570 sonars. The only difference between these sonars is the
angle to which the transducer can be tilted. The SD 570
transducer can be tilted to - 90_, while the SE 570 transducer is
limited to - 45_. All units for the SD 570 and SE 570 have the same
physical size.

The Hull Unit uses an installation trunk which is equal to the old
Simrad SL and SX installation trunks. The Hull Unit can therefore
easily be mounted in an old SL or SX trunk. As an option, an
adapter flange can be delivered for mounting the Hull Unit in an
old SK, SB or SQ trunk. Note that the trunk is not included in the
standard delivery, but can be ordered as an option (see chapter 2.3

2.4 Installation procedures

The installation of the standard SD 570 / SE 570 Sonar systems
includes the following stages:

The installation of the standard SP 270 Sonar system includes the
following stages:

• Mounting the Installation Trunk

• Mounting the Hull Unit

• Mounting the Transceiver Unit

• Mounting the Sonar Control Unit

• Cabling

• Start- Up

• Final Test

Refer to the cable plan, the main interconnection diagrams and the
outline dimensions drawings of the units.

2.5 Equipment responsibility

Upon receipt of the equipment, the installation shipyard and/or
the dealer automatically becomes fully responsible for the
equipment unless otherwise is stated in the contract. This
responsibility covers the storage period before the installation, the
actual installation, commissioning, and the period between the
commissioning and the acceptance of the equipment by the end
user (normally the owner of the vessel into which the equipment
is to be installed).

The guarantee period for the system (as specified in the contract)
begins as soon as acceptance documents have been signed, unless
other arrangements have been made in the contract.

2.6 Receipt, unpacking and storage

On receiving the equipment, the shipyard and/or the dealer
should ensure that the delivery is complete and inspect each
container for physical damage. If the inspection at receipt reveals
indication of crushing, dropping, immersion in water or any other
form of damage, the recipient should request a representative
from the carrier to be present during unpacking.

During unpacking, the equipment should be inspected for
physical damage, i.e. broken controls and indicators, dents,
scratches etc.

If damage to the equipment is discovered, the recipient should
notify the carrier and Simrad so that Simrad can arrange for
replacement or repair of the damaged equipment.

Simrad SD570 / Base version

851--160115 / B

The equipment, once unpacked, must be stored inside in a room
with an atmosphere free from corrosive agents. In addition, the
equipment must be covered to protect it from dust and other
forms of contamination.

Introduction

851--160115 / B

3 GENERAL REQUIREMENTS

3.1 Responsibility and approbation

The Hull Unit of the sonar is generally approved by The
Norwegian Veritas (Organization for classification and registry of
shipping). An approval of the installation must, however, be
applied for in each case to the local maritime authority.

The ship owner and the shipyard are responsible for the
application.

3.2 Compass deviation

When the installation is finished, the compass must be checked
both with the sonar operative and inoperative. The ship owner
and the skipper are responsible for such a check to be carried out.

3.3 Noise sources

Prior to installation, the vessel’s h ull should be thoroughly
inspected in dock. Roughness on the shell plating surface, and
protruding obstacles are examples of noise-causing elements.
These must be smoothed or removed. Also ensure that the
propeller is not chipped or corroded.

3.4 Docking

When dry docking the vessel, make sure that there is enough
room underneath for installation of the sonar trunk and
protection blister (refer to figures 4 and 5 in section Installation
procedures .

3.5 Cabling

If the cable from the wheelhouse to the sonar room passes through
hatches or places where it may be damaged, it should be run
through a pipe. Note that the cable must not be installed together
with high-power cables, antenna cables etc.

1 INSTALLATION PLANNING

Note ! For installation in an already installed trunk system, first read through

chapter 1.3 about the sonar room requirements. Then, for an already

installed SLor SX trunk system, continue to procedure 3 Installation

of the Hull Unit .

For installationin an already installed SK, SB or SQ trunk system,
refer to section Trunk systems in this manual.

1.1 General

This chapter provides the necessary information for the ship

designer to plan and carry out the installation of the SD 570/SE
570 hull system according to Simrad’s requirements. Study this

chapter thoroughly to achieve the recommended knowledge of
the procedures.

Note that individual installation drawings must be designed by
the shipyard, and the construction must be approved by the
classification authorities at the customer’s expense.

Simrad offers free advice for installation planning. The proposal
for the arrangement may be sent to Simrad for comments, or may
be worked out by Simrad. If such assistance is required, the
following drawings should be submitted:

· General arrangement

· Body plan and drawings of bottom tanks and cofferdam

· Sheer drawing

1.2 Location of the Hull Unit

The Hull Unit should preferably be located within 1/10 to 1/3 of
the ship’s length between perpendiculars (LBP), measured from
the fore perpendicular (FP). Refer to figure 1. Larger deviations
from this rule should not be made without consulting Simrad.

The Hull Unit may be located symmetrically on the centre line of
the vessel, or alongside the keel. When determining the exact
location, make sure that the transducer will have free view under
the keel (refer to figure 1).

The Hull Unit trunk must be installed such that it will be vertical
under normal operating conditions.

Water inlets and protruding details which create turbulence,
should not be located in front of the transducer. For the same
reason, check that the shell plating in front of the trunk is not
damaged.

1.3 Sonar room requirements

The sonar room should be dimensioned to house the Hull Unit
and the Transceiver Unit.This becausethe lengthof the flexi-hose
protected cabling from the Hull Unit to the Transceiver Unit is

limited to approximately 3.5 meters.

By installing the units in a well designed sonar room, the risk of
corrosion is reduced, the maintenance is simplified, and the
reliability is increased.

A suggested arrangement of the sonar room is shownin figure 2.
The free space should not be obstructed by girders or pipes etc.,
which might cause problems forthe installationand maintenance
work.

Access hatches

The sonar room must be accessible under all conditions, and the
doors or hatches should be so designed that the installed units can
be removed without being disassembled. A tackle carrier
designed for a load of a minimum of 2 tons should be mounted
above the Hull Unit. The tackle may be used to facilitate the
mounting of the trunk and Hull Unit, and is alsointended for use
in future service of the Hull Unit.

Heating

The sonar room should be furnished with a heating element of
1000 W, mounted close to the floor.

Insulation

The bulkhead must be insulated and plateddown to thefloor.The
insulation should equal a minimum of 50 mm of rock- wool.

Introduction

3

851--160116 / B

Ventilation

The sonar room should preferably be connected to the ship’s
ventilation system. If this is not possible, two 3-inch vent pipes
must be laid from the sonar room to free air on deck. The air inlet
should be close to the floor, while the outlet should be placed as
high aspossible. Funnelsshould bemounted belowthe vent pipes
to collect condensed water.

To ensure the best possible ventilation, the outlet pipe should run
at least 4meters higher than the inletpipe. To keep rain and water
splash out, the pipes should be fitted with goosenecks or cowls.

Cable pipes

If the cable between the wheelhouse and the sonar room passes
through hatches or places where it can be damaged, it should be
run through pipes (2” pipes are recommended).

Bilge pump

The sonar room should be connected to the ship’s main bilge
pump system.If this is not possible, a separatebilge pump for the
sonar room must be installed.

Lighting

To simplify the installation and future maintenance, the sonar
room should be equipped with suitable lighting.

Docking

Make sure that there is ample space below the keel for mounting
the hull system, when docking the vessel.

To facilitate future docking, mark the position of the trunk as
indicated in figure 1

Flooring

When the installation is completed, the sonar room should be
suitably floored.

2 INSTALLATION OF THE SONAR TRUNK

2.1 Mounting of the trunk

The location of the sonar trunk has to be carefully selected, as
described in chapter 1.2. Refer also to figures 4 and 5.

Note the orientation of the centre line of the trunk with regard to
the mounting bolts, shown in figure 3.

Note ! Remove the gasket on the top flange during the welding.

Figure 3 - Orientation of the sonar

trunk

The height from the topof the trunk flange to the underside of the

protection blister must be minimum 920 mm (361/4”) as shown

in figures 4 and 5.

The top flange must be parallel tothe construction loadline in the
fore- and- aft as well as the athwartships direction.

The installation trunk must be welded to an inserted plate which
should be 1.5 timesas thick asthe originalshell plate.The sizemay
be determined by the shipyard or the responsible maritime
authorities. The trunk must be stiffened to the inserted plate by
welding knee-plates on the trunk in both fore-and- aft and
athwartships directions.

Simrad SD570 / Base version

851--160116 / B

2.2 Protecting blister

As illustrated in figures 4 and 5, a steel blister must be fitted for
protection. The blister shown in figure 4 is welded to the shell
plating and then filled with oil to prevent corrosion. This method
provides excellent protection and simplifies maintenance. The
blister shown in figure 5 is of the open type, to be welded to the
shell plating.

2.3 Corrosion protection

As soon as the trunk is mounted, and welding and grinding are
finished, the trunk should be painted with a quality protective
paint.

2.4 Trunk installation measurements

For future use, the measurements of the distance A, and the
heights B and Cshown in figures4 and5 haveto becarried outand

3 INSTALLATION OF THE HULL UNIT

3.1 Unpacking the Hull Unit

In order to prevent damage of the transducer and the transducer
cables while handling the Hull Unit, these parts are especially
protected. This means thatboth the transducer protection and the
cable protection should still be mounted to the Hull Unit when it
is being lowered down into the sonar room (see figure 6).

Figure 6 - Lifting the Hull Unit

fromthe woodenbox,then pulloutthe nailsmarkedwith
Indianink. Fasten thelifting deviceto the twolifting eye
bolts onthe top of the gallows andlift the Hull Unit with
the protections carefully out from the transport box.

3.2 Mounting the Hull Unit

The Hull Unit should normally be oriented with the

hoisting/lowering motor pointing aft (see figure 7). If this

orientation makes the motor control unit onthe HullUnit difficult
to access, the Hull Unit may be oriented in the most suitable
position.

Note ! The motor control unit should never be dismounted from the Hull Unit

(see text above).

j Use a tackle to lower the Hull Unit with the protections

downintothe sonarroom(seefigure 6).Removethe blind
cover from the trunk, and check that the gasket is not
damaged. Store the blind cover in the sonar room for
possible future use.

andconnectorshave tobekeptdry andhandledwithcare
to avoid mechanical damage.

3.3 Staying

The Hull Unit is constructed to be in the lower position with a
maximum speed of 15 knots.Toprevent unwanted vibrations, the
Hull Unit has to be stayed off against the bulkhead. Remove the
lifting rings onthe top of the gallows on the Hull Unitand use the
holes for fastening of the staying in the fore- and- aft direction. In
case of serviceon the Hull Unit,it should be possibleto removethe
staying.

3.4 Alignment of the transducer

Note that the transducer should not be mechanically aligned even
if the Hull Unit is oriented differently from figure 7.

The transducer alignment will be carried out later by turning the
echo picture in the computer.

4 INSTALLATION OF THE TRANSCEIVER UNIT

Note ! The Transceiver Unit must be mounted as a complete unit, i.e. the door

should not be opened until the unit is securely fastened to the bulkhead.

Before starting the mounting of the Transceiver Unit, note that the
distance between the HullUnit and the Transceiver Unitis limited
because of the flexible transducer cables. Also remember to take
into consideration the necessary slack for lowering of the
transducer.

Do not fasten the transducer cables into the Transceiver Unit
before mentioned later in the start- up procedure.

The Transceiver Unit cabinet requires a minimum free bulkhead
space, which is shown in figure 8.

7 CONNECTING AUXILIARY EQUIPMENT

7.1 General

It is not necessary to make the connection of the auxiliary
equipment before the start-up procedure is finished, and this
equipment may therefore be connected later. Anyhow, do not
connect the plugs for the auxiliary equipment to the Sonar
Control Unit before mentioned in a later chapter.

The SD 570 / SE 570 sonars require connection of a speed log and
a course gyro. An inaccurate log or gyro input will cause
inaccurate indication of the vessel and target movements.

Speed log:

· Pulse log: 100, 200 or 400 pulses/nm.

· Serial line, standard NMEA 0183; RS232, RS422 or Current

loop.

Course gyro:

· 3- phase synchro signal, 20- 220V L- L, 50/60/400Hz.

· Gear ratio 1:360, 1:180, 1:90, 1:36.

· 3- phase stepper signal, 20-220V L- L.

Gear ratio 1:360, 1:180, 1:90, 1:36.

· Serial line, standard NMEA 0183; RS232, RS422 or Current

loop.

Echo sounder:

In order to get a depth indication on the catch control page on the
sonar, one of the following Simrad echo sounders can be
connected:

· EQ50, EQ55, EQ100, ES60, ES380 series, ES500 (RS232 serial

line).

Trawl system:

In order to get the trawl information on the sonar display, one of
the following Simrad trawl systems can be connected:

· FS Trawl sonar (RS 232 serial line or 20mA current loop).

· ITI Integrated Trawl Instrumentation (RS232 serial line).

SYNCHRO DATA SPECIFICATIONS LEGAL VALUES
OUTPUT VOLTAGE 20 to 220 VAC
FREQUENCY 50/60/400 Hz
GEAR RATIO 1:360/1:180/1:90/1:36

If it is difficult to find the specifications for the gyro, the output
voltage and frequency can be measured in the following way:

j The output voltage can be measured by an AC voltmeter

or by an oscilloscope on the reference output R1 & R2.

Notethat ifanoscilloscopeisused,thereferenceprobe on

the oscilloscope must not be connected to the mains

ground, and the measured peak to peak value of the

output voltage must be divided by 2 Ö2 to get the RMS

voltage.

j Fill the output voltage value into the table above.
j The frequencycan be measured by an oscilloscope onthe

reference output R1 & R2. Note that the referenceprobe

on the oscilloscope must not be connected to the mains

ground.Calculate thefrequency1/T(T isthe timefor one

sine wave) and fill the result into the table above.

j If the gear ratio of the gyro output also is unknown, this

has to be tried out later when testing the readout of the

gyroon theSonarControlUnit. Insuch case,set thegear

ratio to 1:360.

When connecting the gyro cable to the 15 pin D-connector, note
that each of the three phases S1, S2, S3 and the reference R1 has
three different connection pins, marked L (Low), M (Medium)
and H (High). These pins are used for different gyro output

2.2 Adjusting the middle position switch

Normally, when the transducer is selected to middle position on
the Sonar Control Unit, only one half of the transducerface should
be outside the sonar trunk (see figure 5). The middle position
switch, which is a magnetic switch, must then be adjusted
according to the trunk length:

j With the Hull Unit fully hoisted to upper position,

measure the distance x between the bottom of the
transducerandthetrunkend.Seethelowerpartoffigure

5.
X = mm

If it isimpossible to measure the distance x,it can be calculated by
using the total trunk height C frompage 12in section“Installation
procedures” .

Total trunk height C = mm

-- Distance flange/transducer bottom = 760 mm
= Distance X mm

j Use the hoisting/lowering switch in the motor control

unit to position the transducer in the calculated correct
position x + 240 mm (see figure 5).

j Loosen the bracket for the middle position switch and

aligntheswitchrelativetothemagnetasshownonfigure
