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 op-eration 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 short-cut 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 mistak-enly 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.)

1.6 How to Choose Speed Tracking Mode

The tracking mode is available in ground tracking, water tracking, NAV and Auto/Ex-ternal.

Overview of Tracking Mode

To choose the tracking mode, press the TRACK MODE key. The tracking mode changes according to the setting ([OFF] or [ON]) of [NAV MODE] in the [MENU 4] sub menu. The current tracking mode appears at the top left-hand corner on the screen.

In case of [OFF] of [NAV MODE] The tracking mode changes cyclically in the sequence of ground tracking, water track-ing and auto (or external).

In case of [ON] of [NAV MODE] The tracking mode changes cyclically in the sequence of ground tracking, nav and auto (or external).

Tracking mode Contents GT (Ground tracking) Absolute ship and tide move-ments based on ground and current (tide display (bottom echo must be present).

WT (Water tracking) Ship and tide movements rela-tive to near-surface water and tide differential between tide layers. (The pulse length in this mode must be [NORMAL] and depth greater than 40 m, or LONG pulse length and depth greater than 70 m.)

NAV Ship’s movement as mea-sured by a navigation device and tide movements based on nav speed data.

Note: The accuracy of tide measurement in the NAV mode depends heavily on gy-rocompass accuracy.

AUTO/EXT* (Exter-nal)

Uses ground tracking mode when bottom echo is available and switches to water tracking mode (or [NAV] mode) when bottom echo is lost. The bottom echo is continuously sought, and if re-acquired the ground tracking mode is restored.

*: [EXT] appears in the tracking mode window (top left corner) when [DEPTH

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 com-pensation, weather compensation, etc.) have been made correctly.

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

If the gyro reading is accurate, the current indicator will provide accurate tide informa-tion. 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.

If you encounter such symptoms calibrate the current indicator as shown in the instal-lation manual.

Speed/course

Speed made good and true course are shown. The dis-playable range is 0.0 to

40.0 kn for speed and 0° to 359° for course.

Tide speed and direction

Tide speed and direction is shown for five layers (measuring depths). The displayable range is 0.0 to 9.9 kn for speed and 0° to 359° for course. The depth of each layer is shown at the right or lower-right of the layer number. The figure shown right is an exam-ple of the tide vector display. Data shown depends on the measuring mode as follows;

• 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 equip-ment.

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-er 4/layer 5, the tide differential between layer 1 and layer 4/layer 5 will be displayed.

Water temperature

Water temperature is shown if a water temperature sensor is connected to the current indicator. The display range is -5.00 to 99.99 (°C).

The heading line is a dashed line (white) which shows ship’s heading. It extends from ship’s position (center of vector display) to the edge of the vector display. When the back color of the display is set “WHITE”, the heading line is shown in black, see "BACKGROUND CLR" on page 3-5. You can hide the heading line, see "HEADING LINE" on page 3-6.

Note: If the heading line overlap on the ship’s speed vector, ship’s speed vector has higher priority so the heading line is hidden.

Tide/Tide differential vector

Tide speed and direction for five layers are shown in the tide vector circle.

Also, the two tide differ-ential are shown. You can hide their vector, see

"TIDE VECTOR (LAYER
