VOYAGER

DEPTH

INSTALLATION

AND

OPERATING

INSTRUCTIONS

Please

read

this

booklet

thoroughly

before

installing

and

operating

this

equipment

.

INTRODUCTION

The

VoyagerDepth

Sounder

is

a

microprocessor

controlled

instrument

which

operates

by

measuring

the

time

interval

between

transmission

and

reception

of ultrasonic

pulses

from

the

seabed

via

a

piezo

electric

transducer

fitted in

the

hull

of

the

boat

.

Depth

information

is

displayed

on

a large,

custom

made,

liquid

crystal

display

in

both analogue

and

digital

form,

thus

combining

the

accuracy

of

digital

information

with

the

more

easily

assimilated

trend

indications

of

analogue

device

.

Designed

with ease

of

operation

in

mind,

there

is

no

requirement

for the

user

to

adjust

gain,

range

or

output

power

of

the

Voyager

Depth

instrument

.

The

sensitivity

of

the

receiver

and

the

RMS

output

power

are

precisely

controlled

by

the

microprocessor

so

that

the

instrument

will

always

operate

at

its

optimum

setting

for

all

possible

combinations

of

depth

and

seabed

conditions

.

This, together

with

the

ability

to

discriminate

between

true

and

false

ethos,

provides

a

steady

and

accurate

reading

of

depth,

which

is

not

effected

by

external

interference

.

Additional

facilities

which

are

provided

include

depth

readings

in digital

form

up

to

300 metres

(975

feet)

under

optimum

conditions

.

Analogue

depth

information

up

to

100

units

(metres

or

feet,

user

selected)

.

The

Logarithmic

scale

provides

expanded

discrimination

in

shallow

water

.

Audible

and

visual

deep

draught

up

to

m

.

Built

in

display

illumination

for

night

time

use

.

The

instrument

has

been

designed

for

permanent

installation

in

a

bulkhead

or

dashboard and once

correctly

installed

.

i

s

completely weatherproof

.

Adjustments

to Calibration,

Alarms

and Keel

Offset

can

be

made

using

the

five

key

tactile

keyboard

.

As

an

option,

a

swivel

mount

is

available

but

this

method

of

mounting

is

only

recommended

for

dry

cabin

installations

.

INSTALLATION

Transducer

Installation

(Through

Hull)

WARNING

:

The

co-axial

cable

is

sealed

into

the

stem

of

the

transducer

and

if

damaged

in

any

way

cannot be

reconnected

.

The

transducer

lead

has

a

nominal

length

of

22

.3

ft

(6

.8

m)

and

should not

be

extended

or

cut

without

the

advice

of a

service

engineer

.

Any

excess

cable

should

be

coiled

away

from

excessive heat

or

sources

of

electrical

interference

.

Transducers

with

longer

cable

can

be

supplied

to

special

order

.

For

full

depth

performance

the

transducer

stem

should

be

mounted

as near

vertical

as possible

.

Install

the

transducer

in a

part of

the

hull

which

is

as

clear

as

possible

from

aerated

or

turbulent

water and

where

accidental

damage

is

unlikely

to

occur

.

Normally

a

position

slightly

aft

of

amidships

is

preferable

.

For

fin-keel

sailing

boats

it

may

be

preferable

to

fully

recess the

transducer

into

the

stem

so that

the

face

is

completely

flush

.

It

should

be

remembered

that

the

beam

angle

of

the

transducer

is

±22'/2

°and

care

should

be

taken

that

a

false

echo

is

not

created

by

the

keel

.

If a

single

transducer

is

installed

on

the

centre

line

of

the

boat

depth

readings

will

be

obtained

up

to

an

heel

angle

of

22'/2°

.

If

two

transducers

are

required,

to

avoid

fin-keels for instance,

then

each

should

be

fitted

in

opposite

bilges facing

outward

at

an

angle

of

approximately

15°

.

By

using

an

automatic

changeover

switch

(optional

extra)

available

from

all

good

chandlers,

a

twin

transducer

installation

will

enable

the

Voyager

Depth

to

give

accurate

depth

readings

to

an

heel

angle

of 37

1/2 °

.

The

following

illustration

indicates

typical

transducer

installations

using

a

wooden

fairing

block

outside

the

hull

.

The

fairing

block

has

been

carefully

bored, carved

and sanded

to a

streamlined

shape

avoiding

the

creating

of

turbulent

water

which

may

reduce

or

even

prevent

depth

indication

when

the

boat

is

travelling

at a

speed

.

In

one of

the

examples

shown,

an

internal

fairing

block

has

been used

for

strength

and

sealing

and

to

allow

for

hull

curvature

.

The

installation

should

be

carefully

rendered

watertight

by

using

a

sealing

compound

between

all

mating

surfaces

.

Do

not

over-tighten

the

nuts

on

the

transducer

stem

.

TRANSDUCER

INSTALLATION

IN

HULL

(GRP)

As

an

alternative

to

mounting

the

transducer

through

the

hull

with

the

face

in

direct

contact

with

the

water,

it

may

be

positioned

inside

a

glass-fibre

hull

by

means

of

an

In

Hull

Transducer

Kit

as

shown

in

Fig

.

2

.

The

In Hull

Transducer

Kit

is

available

from most

Chandlers

and

Boatyards,

as

an

optional

extra

.

The end

cap

of

the

In Hull

Transducer

Kit

is

provided

with

a

push-out

insert

making

it

suitable

for

the

stem

diameter

of

the

Voyager

Depth

transducer

.

This

method

of

installation

has

the

dual

advantage

that

no

hole

is

made

in

the

vessel's

hull

and

that

the

echo

sounder

and

transducer

can

easily

be

removed

for

examination

or

installation

elsewhere

.

It

should

be

mentioned

however,

that

although

the

accuracy

will

in

no

way

be

affected

by

installing

the

transducer

inside the

hull,

the

maximum

range

sensitivity

may

be

reduced

depending upon

the

thickness

and

quality

of

the

glass-fibre

.

We

do

not

recommend

this

method

of

installation

if

the

thickness

of

the

glass-fibre

exceeds

three

quarters

of an

inch

.

Neither

do

we

recommend

its

use

in

hulls

of

wood,

steel

or

aluminium

although

this

method

of

installation

has

been

found

acceptable

with

these

materials

in

some

cases

.

Full

installation

details

are

supplied

with

the

In

Hull

Transducer

Kit

and

copies

are available

on

request

to

Seafarer

Navigation

International

Limited

.

Main

Instrument

Installation

When

selecting

a

suitable

location

for the

display

unit,

it

should

be

noted

that

the

contrast

of

the

LCD

display

is

greatest

when

viewed

at

eye

level

or

slightly

below

eye

level

.

If

the

display

is

viewed above

eye

level,

then

some

loss

of

contrast

will

be

experienced

.

A

compass

safe distance of

approximately

two

feet

shuld

also

be

observed

.

Having

selected

a

suitable

location, the

mounting

holes

can be

cut,

following

the

template

supplied

with

this

book

.

Voyager

Depth

will

operate

only

from

the

ship's

12

volt

DC

supply

and

it

is

recommended

that

an

on/off

switch,

capable

of

supplying

5

amps

at

50

volts,

is

connected

in

series

with

the

positive

supply

line

between

the

unit

and

the

boat

supply

.

This

will

allow

the

depth

sounder

to

be

operated

independently

of

other

boat

equipment

.

Next,

complete

all

other

interconnections

as

detailed

in

Figure

3

.

The

display

unit

is

supplied

complete

with

an

O

ring

sealing

gasket but

is

should

be

noted

that this

will

only

be

fully

effective

if

the

mounting

surface

is

perfectly

flat

.

If

this

is

not the

case,

then

a

suitable

sealant

should be

used

between

surfaces

before

tightening

the

nurled nuts

.

Audible

Alarm

Module

This

unit

can

be

located

in

any

sheltered

position

and

the

leads

extended by

using

a

terminal

block

and

additional

cable

as

required

.

.

This

indicates

that

no

value

of keel

has

been

-

entered and under

these

conditions,

all

depth

measurements

will

be

taken

from

the

.

NOTE

-

Whenever

the

Voyager

This

facility

enables

zero

depth

on

the

display

to

be

set at

and

a

(T)

keel

offset

of

2

.5

feet

is

entered, then

the

true

will

be

displayed

.

Conversely,

if

a (-)
