We are confident you will discover why FURUNO has become synonymous with quality and reliability. The FURUNO DS-80 displays ship’s speed relative to water, using the Doppler principle; ship’s speed is measured by detecting the Doppler shift frequency from the signal returned from the watermass. Dedicated in the design and manufacture of marine electronics equipment for half a century, FURUNO Electric Company has gained an unrivaled reputation as a world leader in the industry. This is the result of our technical excellence as well as our worldwide distribution and service network. The output is interfaced with ARPA, AIS, and other shipborne equipment in IEC 61162-1 format. Please carefully read and follow the safety information and operating and maintenance instructions set forth in this manual before attempting to operate the equipment and conduct any maintenance. Your Doppler speed log will perform to the utmost of its ability only if it is operated and maintained in accordance with the correct procedures. • Pair-beam system effectively reduces error caused by pitching. The transducer assembly symmetrically emits two sonic beams, one fore and the other aft. By averaging the Doppler shift in both directions accurate speed data is available under rough sea conditions. The main features of the DS-80 are • Simple operation. In most cases all that is required to display ship’s speed is to turn on the equipment. • Speed and distance information on the adjustable-contrast LCD display. This equipment is designed, produced and documented by FURUNO Electric Co., Ltd., complying with ISO 9001 standards as certified by the Lloyd’s Register of Quality Assurance System. • Analog display, digital Indicator and digital distance indicator display optionally available. • Conforms to the following standards: IMO A.824(19), as amended by MSC.97(72), IMO A.694(17), IEC 61023, IEC 60945 (3rd edition), IEC 61162-1 (2nd edition).. 1 SYSTEM CONFIGURATION DISPLAY UNIT DS-800 TERMINAL BOX DS-802 DIMMER MF-22L-1/MF-22L-2 IEC 61162-1 Input Power ON SW Signal Distance Run Signal IEC 61162-1 Output DISTRIBUTION BOX DS-801 DIMMER MF22L-1/MF22-2 TERMINAL BOX DS-802 JUNCTION BOX CI-630 TRANSCEIVER UNIT DS-810 DIGITAL INDICATOR DS-830 DISTANCE INDICATOR DS-840 DIMMER MF-22L-1/MF-22-2 RANGE SWITCH BOX DS-389 115/230 VAC ANALOG DISPLAY UNIT MF-22A-1 SHIP'S MAINS 115/230 VAC : STANDARD SUPPLY TRANSDUCER DS-820 : OPTIONAL SUPPLY : LOCAL SUPPLY 2 PRINCIPLE OF OPERATION The Doppler speed log measures ship's speed by using the Doppler Effect, which is observed as a frequency shift resulting from relative motion between a transmitter and receiver or reflector of acoustic or electromagnetic energy. A common example of the Doppler Effect is a train. When a train is approaching, the whistle has a higher pitch than normal. You can hear the change in pitch as the train passes. The relative motion causes the Doppler shift and the ultrasonic waves reflected at the watermass (plankton or any underwater objects) are received at the frequency of fr = fo + fd where fd is the number of frequency shifts counted at the receiver circuit. To calculate ship’s speed, the following formula is used. V = fd/fo • c/2sinθ c: Underwater velocity The DS-80 has a pair-beam, one directed in the fore direction and the other in the aft direction, which emits ultrasonic waves at Note that the sound velocity in water changes with water temperature and water pressure but the DS-80 readout is automatically compensated for change by using a temperature sensor. an angle of θ to the waterline towards ship’s fore and aft directions. The frequency of the received signal is then compared with that of the transmitted frequency to measure doppler shift to calculate ship’s speed. V SEA SURFACE θ fo fr = fo + fd WATERMASS 3 REMARKS ON USAGE Remarks on Usage The accuracy will not be affected by: • - water temperature (sound velocity) The DS-80 measures ship’s speed by detecting the Doppler shift frequency of the echo reflected by a watermass (water layer containing plankton and other microorganisms) located within the measuring area, which is usually about 2 m. In some instances, however, no signal is returned because of too few plankton in the sensing depths. This phenomenon can occur in particular areas in particular seasons. The probable cause is the plankton are lying in deep water because an ice-melted cold water mass covers the sea surface. Similar cases may also occur in a freshwater lake. Under these circumstances the DS-80 will not show the correct ship’s speed. • salinity • pitch/roll ±10° Beware of Transducer Location The transducer may be damaged if it hits the dry dock blocks. Take the following measures to prevent damage to the transducer. 1. Before delivering the ship, draw up a suitable docking plan taking into account the dimensions and location of the transducer. Store the plans onboard the ship. 2. Place the dry dock blocks according to the plan. Conditions Affecting the Accuracy 3. Have a diver check the position between the transducer and the blocks before removing the water. Confirm that the transducer will not touch the blocks. (with ref to IMO A.824/3.3) The Doppler speed log DS-80 is designed for reliable and accurate performance through FURUNO’s long experience and advanced technology. It operates on the best choice of system frequency and power output. As far as the sonic energy is used, the performance (accuracy) may be reduced or even lost under: • rough weather (may be sea state 6 or severer) • improper location of sensor, e.g., too close to the propeller, thrusters, drain tubes, echo sounder transducer • depth under the keel if less than 3 m 4 1 OPERATION OF DISPLAY UNIT 1.1 Controls Omnipad Selects items, options on menus.

Failure of correction in low temperature can result in a maximum error of –0.8 kt or 5.3% for 14.2 kt readout. IMO limit of ±2% is exceeded over 10.0 – 30.0 kt reading but correction by this graph brings a correct measurement. At +55°C, an error of +0.0 kt (+2.7%) occurs at a speed of 30 kt; no other point IMO limit of ±2% is exceeded. When the digital display and analog display readouts are different, take precedence of the digital readout. At temperatures 0°C to 50°C, the speedometer never exceeds the IMO limits. 13 3 MAINTENANCE, TROUBLESHOOTING WARNING CAUTION ELECTRICAL SHOCK HAZARD Do not open the equipment.
