TRANSDUCER ANTI-FOULING

Following

installation

the water exposed face

of

the

transducer

may

be

painted

with one

thin

coat

of

hard

Antifouling,

carefully

applied

sa

that

the

pa

int

does

not

farm

or

trap

air

bubbles.

Care

should

be

taken

not

to

damage

the

transducer

face

or

the piezo electric crystal

that

it protects.

Accidental

damage

to this sealed

unit

cannot

be

repaired.

(Optional)

As

an

aJtefllative

to

mounting

the

transducer

through

the huil

with

the

face in

direct

contact

with

the water,

it

may be

positioned

inside a

glass-fibrt'

huil

by means

of

an

In

Huil

Transducer

Kit

as

shown

in Fig.

2.

The

In Hul!

Transducer

Kit

is

avaiJable from most

Chandlers

and

Baat

Yards, as

an

optional

extra.

The

end

cap

of

the

In

Huil

Transducer

Kit

is

provided

with

a

push-

out

insert

making

it

suitable

for

the

stem

diameter

of

bath

the

Sea

farer

600

and

the

Seafarer

3/4

transducers.

This

methad

of

installation

has the

dual

advantage

that

na

hole is

made

in

the

vesse['s

huil

and

that

the echo

sounder

and

transducer

can

easily

be

removed

for

examination

or

installation

eJsewhere.

It

should

be

mentioned

however,

that

although

the

accuracy

will in

na

way

be

atIected

by installing the

transducer

inside

the

huiL the

maximum

range sensitivity may be reduced

depending

upon

the thickness

and

quality

of

the glass-tibre.

We

do

not

recommend

ihis

methad

of

installation

if

the

thickness

of

the glass-

libre exceeds three-q uariers

of

an

inch.

Neither

do we

recommend

its use in hul!s

of

wood, steel

Or

aluminium,

although

this

methad

of

installa-

tion has been

found

accepiable

with

these

materials

in

INSTRUMENT INST ALLA

nON

WARNING:

Thc

location

of

the

instrument

s

hould

be

at

least 2 feet

(61

ems.)

from

a magnetic

compass

With

the

bracket

provided

the

instrument

may

be

mounted

in

any

position.

as

the

can

be

rotated

through

0

(The

brackei

is design-

•

ed to be slightl y

undersized

to ensure a

good

grip

on ihe case).

This

means

that

it

can

be

facing

down

from

a

cabin

roof,

or

on

top

of

an

instru-

ment

panel

or

console,

or

side

mounted

by

the

cbari

tabie.

lf

the

instrument

is

mounted

out-

side

or

in

a cockpit. a sheliered position

should

3

be chosen, since

although

the

instrument

is

water

resistant

it

is

not

fully

waterproof.

For

this

reason

it

is

advisab

.le to

provide

a cover

or

some

additional

protection

against

extreme

climatic

conditions.

FLUSH MOUNTING

An

alternative

method

of

mounting

is to fully

recess the

instrument

into

a

panel

or

bulkhead

using a flush

mounting

nange.

The

template

provided

with

the

operating

booklet

may

be used

for

making

the

appropriate

cut

out

in the

bulkhead.

Remove

the two

plastic

side

mounting

knobs

and

cut

the

projecting

screw

threads

back

to the metal

flange

on

each

sicle

of

the

instrument

case.

Fit

the plastic

mounting

beze! to tbe

instrument

by

slacking the

four

fixing screws

at

the

rear

of

the

case sufficient to allow the be zei (which is

in

two

halves)

to

be

slipped

in between

the

front

panel

and

the case.

Re-tighten

the

four

screws

trapping

the

bezel in position.

The

instrument

can

now

be

pushed

into

the

cutout

in

the

bulkhead

from

the

front

and

secured with

eight

counter

sunk

SCIews

in

the

bez

e!.

POWER SUPPLY

The

instrument

may

be

powered

by

either

an

internal

battery

or

ship's

supply

of

nominal

12/

24

or

32

volts

D.e.

without

adjustment.

The

rear

battery

compartment

cover

must

be remov

ed

to

allow access to the connections.

If

the

instru-

ment

is to

be

powered

from

the

ship's

supply,

attention

is

drawn

to

the

fa ct

that

the

internal

battery

terminals

MUST

remain

stowed

in

their

stowage position.

The

unit

will

not

operate

on

an external supply unless

the

battery

terminals

are

in

the

stowage position.

(It

that

an

is

mounted

in

a

vessel with

The

depth

can

be set

on

any

range

up

to

the

equivalent

of

approximately

60 feet (20

REPEAT

METER OPERATION

The

is

provided

with three

depth

scales

similar

to

those

of

the

instrument.

The

scales

may

be

independently

selected

provided

that

the

main

instrument

is on a

de

eper

range

than

that

required

on

the

1t

is

recom-

mended

that

the

Seafarer

600

be

set

to

the

deep

range

scale "c"

and

the

"gain"

adjusted

to give

a

good

solid echo.

This

eliminates

as

far

as

possible

the

need

to

keep

re-setting the

"gain"

co

ntrol

as the

depth

increases.

With

the

ma

in

instrument

on

range

"C"

the

minimum

depth

reading

is

approximateJy

6 feet (2 metres). Switch-

ing to ranges

"A

"

or

"B"

reduces the

minimum

depth

reading

to

approximateJy

3 feet (I metre).

The

minimum

depth

is

Jimited by a

bubble

ion

circuit

in

the

to

pre

ve

nt

faJse

readings

caused by

air

in the
