FOREWORD

A Word to the Owner of the CI-68

Congratulations on your choice of the FURUNO CI-68 Doppler Sonar Current Indicator. We are confident you will see why FURUNO has become synonymous with quality and reliability.

For over 60 years FURUNO Electric Company has enjoyed an enviable reputation for innovative and dependable marine electronics equipment. This dedication to excellence is furthered by our extensive global network of agents and dealers.

Your current indicator is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless installed, operated and maintained properly. Please carefully read and follow the recommended procedures for operation and maintenance.

Thank you for considering and purchasing FURUNO equipment.

Features

• With heading data from a gyrocompass, satellite compass, etc., the absolute movements of tide measuring layers is displayed, in colors.

• When ground (bottom) reference is not available acoustically; namely, ship is in deep water, this equipment provides absolute movements of measuring layers by receiving position (or speed) data from a GPS navigator and heading data from a gyrocompass or satellite compass.

• Single-mold transducer plus compact monitor unit, control unit, transceiver unit and junction box (option) permit installation on small vessels.

• Data is displayed on a bright, non-fading 10.4 inch TFT LCD. Background color is selectable from three colors.

• Commercially available monitor may be used in lieu of the LCD monitor.

• Six display modes to discern tide movement from a variety of angles.

• Logical keyboard layout and menu structure for intuitive operation. Function key provides shortcut menu operation.

• Triple-beam system for automatic error compensation against pitching and rolling.

• Echo level continuously displayed on the screen, for monitoring signal conditions on three sounding beams.

• Bottom echo can be found using external depth data. Further, the bottom echo can be acquired manually by monitoring the echo level display. This is useful when in deep seas, air bubbles block reception of the bottom echo, or a thick layer of plankton or a large fish school is mistakenly tracked as the bottom echo.

• Various alarms: tide, tide differential, speed, trip, etc. Audible and visual alerts are released if alarm condition is violated.

• Graph display shows past current data.

• Water temperature graph helps locate current rip. (Temperature sensor required.)

1.8 How to Set the Ship’s Heading

The current indicator has a NAV mode which measures tides in deep waters where ground tracking is not available. To achieve reliable measurements, however, you must feed accurate heading (gyro) data and ship’s position (or speed and course) data to the current indicator.

1. Confirm that the gyro has settled and all necessary compensations (latitude compensation, weather compensation, etc.) have been made correctly.

2. Adjust the AD Converter to show the same reading shown on the master gyrocompass. Do not make the adjustment while the ship is turning.

Master compass

1. OPERATIONAL OVERVIEW

AD converter

If the gyro reading is accurate, the current indicator will provide accurate tide information. If gyro data is wrong, the following symptoms will appear.

• The drift angle in the ground tracking mode is not the same as that in the nav mode

or is shown in the direction reverse of the actual direction. Drift angle in ground tracking mode: Difference between ground speed and course and gyro heading. Drift angle in nav mode: Difference between nav course and gyro heading.

• Tide speed and direction in the ground mode is not the same as that in the nav

mode. And the tide correlation (relative angle, size) between layers is different.

Ground Tracking Mode

If you encounter such symptoms calibrate the current indicator as shown in the installation manual.

Speed

Direction

• Ground tracking mode: Speed and di- rection values of measuring layers represent movement of layer relative to ground.

• Water tracking mode: Speed and direction values of measuring layers represent movement of layer relative to near-surface water.

• Nav mode: Speed and direction values represent movement of measuring layers relative to pseudo ground. Required the ship’s speed data from an external equipment.

Tide differential

Tide speed and direction differential are shown between basic layer and the reference layer. The displayable range is 0.0 to 9.9 kn for speed and 0° to 359° for course. The basic layer and the reference layer are selected with [REF TIDE DIFF] and [TIDE DIFF1 (2)] on the [MENU 3] sub menu. For example, if the basic layer is layer 1 and the reference ones are lay-

4. MAINTENANCE & TROUBLESHOOTING

This chapter contains maintenance and troubleshooting instructions to be followed to obtain optimum performance and the longest possible life of the equipment. Before attempting any maintenance or troubleshooting procedure, please review the safety information below.

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel should work inside the quipment.

4.1 Maintenance

Routine maintenance

Regular maintenance is important for good performance. Check the following on a regular basis to keep the equipment in good condition.

• Check that the connectors are tightly fastened.

• Check the ground wire and ground terminal for rust. Clean if necessary. Confirm that

the ground wire is tightly fastened.

• Remove dust and dirt from the monitor unit with a dry, soft cloth. Do not use chemical

cleaners to clean any part of the monitor unit. They can remove paint and markings.

• To remove dirt or salt deposits, use an LCD cleaner, wiping slowly with tissue paper so

as to dissolve the dirt or salt. Change paper frequently so the salt or dirt will not scratch the LCD. Do not use solvents such as thinner, acetone or benzene for cleaning. Also, do not use degreaser or antifog solution, as they can strip the coating from the LCD.

NOTICE

Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment.

Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors.

Transducer

• Check the zinc plate attached to the transducer for corrosion regularly and replace it if

it is corroded. It should be replaced when the ship is drydocked. If the plate is not replaced, corrosion may occur. This may allow the transducer to fall out from the hull, allowing water to leak inside the vessel.

• Do not paint the transducer face.

• When the vessel is drydocked, remove marine growth from the transducer. Marine life

adhering to the transducer may cause a considerable drop in performance.

4-1

4. MAINTENANCE & TROUBLESHOOTING

Fuse

The transceiver unit, monitor unit and control unit are equipped with a fuse which protects them from overvoltage and overcurrent. If a fuse blows, find the cause before replacing it. If it blows again after replacement, contact your dealer for advice. All fuses are located inside the units. Therefore, have a suitably qualified technician replace the fuses.

Unit Type Code No.

Monitor Unit FGMB 3A 125V 000-104-909

4.2 Troubleshooting

Below are simple troubleshooting procedures which the user may follow to try to restore normal operation. If normal operation cannot be restored, do not attempt to check inside any unit. Any repair work is best left to a qualified technician.

Case Remedy

Nothing appears on the screen when the power switch is pressed.

Ship’s track is not displayed. • Turn on [SHIP TRACK] in the [DISP 3] sub menu.

Bottom echo is not shown on the echo level display.

• Check that the power cable is firmly connected.

• The fuse may have blown. Request replacement of the fuse.

• Adjust brilliance.

• Check if the setting of [ECHO RANGE] in the [MENU 4] sub menu is too low.

• Bottom is deeper than measuring range.

• Check setting of [GAIN] in the [MENU 4] sub menu.

4-2

Echo display is interrupted. • Suspect poor measuring conditions.

• Marine life may be adhering to the transducer.

• Bottom is covered with sludge or the like.

Tide data is unstable. • Adjust [TIDE AVERAGE] in the [MENU 3] sub

menu.

Interference is present. • Check ground for corrosion.

• Check if the cables of other equipment are near the transducer cable.

4.3 Diagnostics

The current indicator is equipped with three test facilities to check it for proper operation. When you turn on the current indicator, the selftest starts automatically and then a normal operation.
