SAFETY INSTRUCTIONS WARNING ELECTRICAL SHOCK HAZARD CAUTION Do not open the equipment. Do not use the equipment for other than its intended purpose. Only qualified personnel should work inside the equipment. Improper use of the equipment can result in personal injury or equipment damage. Immediately turn off the power at the switchboard if water leaks into the equipment or an object is dropped into the equipment. Continued use of the equipment can cause fire or electrical shock.
CAUTION If the optional rate gyro is installed, turn on the power when the ship is dead in water or running straight. 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.

5. NAV DATA MODE OPERATION This section describes the operation on the NAV DATA MODE as well as the readings on the screen. 8 23 Internal Basic Operation You may operate this mode with the following key switches. TRACKING MODE Chooses the tracking mode for ship’s speed measurement: Ground, Water or Auto. Normally select “Auto” for automatic changeover to “Water” when the ground tracking is not attainable. The Ground tracking is normally attainable up to a 200m deep bottom.
3. Ship’s Heading Heading data derived from gyrocompass is indicated. 0° is displayed in the case of no gyrocompass connection. 4. Drift Drift (angle between ship’s heading and ship’s course) is displayed. See the illustration on page 5-2. 5. Transverse Speed at Bow Value over-the ground or through-the-water is displayed as determined by the tracking mode. 6. Longitudinal Speed Value over-the-ground or through-the-water is displayed as determined by the tracking mode. 7.
distance run between ports and the total distance the total distance run from port “A” to “D”. Resetting voyage distance To reset the voyage to zero, press the VOYAGE RESET key. Resetting voyage distance The total distance can be set to any desired value on the initial setup menu. See page 9-12. Selecting unit of distance You may select the unit of distance “nm” (nautical mile) or “km” on the system menu. See page 11-1. 22.
6. NAV DATA MODE OPERATION This section describes the operation on the SPEED DATA MODE as well as the readings on the SPEED screen. 9 Basic Operation You may operate this mode with the following key switches. TRACKING MODE Chooses the tracking mode for ship’s speed measurement: Ground, Water or Auto. Normally select “Auto” for automatic changeover to “Water” when the ground tracking is not attainable. The Ground tracking is normally attainable up to a 200 m deep bottom.
Interpreting Readings and Advanced Operation In this section, the number beside each header corresponds to the same number in the illustration of the SPEED DATA MODE screen on the preceding page. If there is an operation related to a headed item, the operating procedure is shown. 1. Echo Monitor Monitors received echoes for the past two minutes, showing echo type as follows. Three modes are available: • Ground tracking echo (green) • Water tracking echo (blue) • No echo (background color) 2.
In the inclined seabed, there may be a difference between the under-keel clearance measured by DS-30 and that measured by an echo sounder. 8. Total Distance The total distance run is displayed. Resetting Total Distance The total distance run can be set to any desired value on the initial setup menu. See page 9-11. Selecting Unit of Distance You may select the unit of distance “nm” (nautical mile) or “km” on the system menu. See page 11-1. Total Distance Run. 9.
7. BERTHING MODE OPERATION This section describes the operation on the BERTHING MODE as well as the readings on the screen. External HDG 14 The berthing mode requires gyrocompass connection. Basic Operation You may operate this mode with the following key switches. TRACKING MODE Chooses the tracking mode for ship’s speed measurement: Ground, Water or Auto. Normally select “Auto” for automatic changeover to “Water” when the ground tracking is not attainable.
13. Ship’s Speed The ship’s speed over-the-ground or through-the-water is displayed as determined by the tracking mode selected. To judge which speed is being displayed, look at item 7: ground or water. 14. Rate Sensor The rate sensor chosen in the INT. SETUP menu is displayed: Internal, External ROT or External HDG.
Interpreting the display No Display Item 1 Transverse speed at bow 2 3 Indication/Remarks Speed over the ground or through-the water is displayed depending in the tracking mode.

Range Scales Specify range scales for the berthing mode, ship speed and under-keel clearance graphic displays. When this item is selected, the Sub-2 menu as shown below is displayed. Choose at least two ranges on each item. Ship Speed Choose ranges to be registered on SPEED RANGE key for ship’s speed graphic display. “Auto” provides automatic selection. UKC Y-axis Choose ranges to be registered on the DEPTH key for Y-axis of under-keel clearance (UKC) graphic display. “Auto” provides automatic selection.

Item Description Selection Current Reference Choose either data from nav sensor or water reference to calculate speed/direction of water current and wind when ground tracking is not attainable. Yes: Data from nav sensor is used when ground tracking is not attainable. No: Speed/direction of current and wind is measured with respect to water mass in the water tracking depth, when ground tracking is not attainable. When a GPS navigator is connected to the DS-30, it is recommended that “Yes” is selected.

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%. 3. Display a. Display Unit b.
