should work inside the

equipment.

Improper use of the equipment can result

in personal injury or equipment damage.

Turn off the equipment immediately if

you feel it is abnormal.

Immediately turn off the power at the

switchboard if water leaks into the

equipment or an object is dropped into

the equipment.

Turn off the power from the switchboard if

the equipment is emitting strange noises

or becomes excessively hot. Contact your

dealer for advice.

Continued use of the equipment can cause

fire or electrical shock. Contact a FURUNO

agent for service.

The useable ambient temperature range

is 15°C to 55°C.

Do not place liquid-filled containers on

the top of the equipment.

Do not use the equipment out of the

above temperature range.

Fire or electrical shock can result if the

liquid spills into the equipment.

Do not place objects around the

equipment.

Do not disassemble or modify the

equipment.

Overheating may result.

Do not power the equipment when the

transducer is in air.

Fire, electrical shock or serious injury can

result.

The transducer may become damaged.

Handle all units carefully.

Keep the equipment away from rain

and water splash.

Fire or electrical shock can result if the

rain or water gets into the equipment.

Damage can lead to corrosion.

Do not use chemical cleaners such as

alcohol, acetone and benzine to clean

the equipment.

Do not operate the equipment with wet

hands.

Electrical shock can result.

Chemical cleaners can remove paint and

markings. Use only a soft, dry cloth. For

stubborn dirt, use a soft cloth moistened

with water-diluted mild detergent.

Keep heater away from equipment.

A heater can melt the equipment's power

cord, which can cause fire or electrical

shock.

When dry docked remove marine life

from the transducer.

Use the proper fuse.

Remove marine life to maintain good

sensitivity.

Fuse rating is shown on the equipment.

Use of a wrong fuse can result in damage

to the equipment.

Do not paint the transducer face.

Further, handle the transducer with

care.

Paint will affect equipment performance.

CAUTION

If the optional rate gyro is installed,

turn on the power when the ship is dead

in water or running straight.

MAIN DISPLAY UNIT

DS-300/301

The heading generated by the rate gyro

is used as reference, therefore turning on

the equipment while the ship is turning will

result in large heading errror.

1. GENERAL

The DS-30 is a highly–advanced, precision Doppler Sonar which incorporates FURUNO’s long

established ultrasonic technology.

It provides accurate displays of ship’s speed over a wide range from dead slow to maximum.

Speeds are detected relative to the ground or water both fore-aft and athwarthship. This feature

allows precise docking of mammoth tankers to oil loading/unloading facilities, as well as safe

navigation in narrow channels or straits.

Features

1) High measuring accuracy of ± (0.2% + 0.01 mm/sec) or better for low longitudinal speed, even in

shallow waters with under keep clearance as little as 1 meter, enables close control of speed and

safe berthing and anchoring operations.

2) Ground tracking up to 200 m provides accurate ship’s ground speed in most coastal waters.

3) Single hull unit composition with employment of the rate-of-turn gyro economizes installation

and maintenance costs. (Most other doppler sonars use two hull units: one each for measuring

ship’s transverse speed at the fore and the stern.

4) Rate-of-turn gyro uses optical fibers instead of moving parts, providing high reliability.

5) Logically arranged presentations of information on the color LCD for instant recognition of

ship’s motion and speed together with under-keel clearance, current and wind conditions.

6) GPS navigator connection provides ship’s ground speed at all times.

7) Conforms to the following standards: IMO A.824(19), as amended by MSC.96(72), IMO

A.694(17), IEC 61023, IEC 60945 (3^rdedition), IEC 61162-1 (2^ndedition)

a. Ship's Speed

・±0.2% or ±0.01 m/sec for low ship's speed ground tracking.

・±1.0% or ±0.1 knots for water tracking mode and high ship's

speed ground tracking (clearance of more than 30m).

・±1.0% or ±0.04 m/sec for port-stbd at stern (ship's length 400 m)

[Influence of ship 's inclination and vibration excepted. With

Laser Gyro DS-340]

・±1.0% or ±0.06 m/s (0.1 kt) for port-stbd at stern (ship's length

approx. 340 m)

[Influence of ship 's inclination and vibration excepted.With a

gyrocompass compatible with IMO performance standard

(ROT accuracy: 0.5º/min), receiving ROT signal less than one

sec. interval. The accuracy is dependent on the performance of

the gyrocompass.

b. Sea Depth (clearance) : ±1.0% or ±0.1m

(at 1500 m/sec of sound velocity and by converting inclined

beams to vertical, without consideration of temperature error.)

±1.0% or ±0.1 nm

±2.0% or ±0.2 kt

c. Distance Signal

d. Current Speed

NOTE 1: The speed error which results from variation of sound velocity by water temperature is

automatically compensated by water temperature measured with temperature sensor mounted on the

transducer: The salinity does not affect accuracy.

NOTE 2: Ship’s static inclination (trim and heel) degrades accuracy by 100(cosθ-1)%

(where θ = angle of inclination). The error caused by this inclination can be corrected by entering trim

and heel angles (-12.5° to + 12.5°) on the OFFSET DATA menu.

NOTE 3: Ship 's rolling/pitching degrades accuracy by 0.2% for ±5° rolling/pitching and 0.65% for ±10°.

The error is 1% when it is 11.5%.
