GENERAL SAFETY WARNINGS

CVR-010

General Safety Warnings – 1/ 2

(1) THE REAR PANEL TRANSDUCER CONNECTOR RECEPTACLE IS

EMITTING EXTREMELY HIGH VOLTAGE RADIO–FREQUENCY PULSES WHEN THE EQUIPMENT IS TURNED ON.

THE CONNECTOR IS COVERED WITH A SCREW–LOCKED

PROTECTIVE RUBBER CAP WHEN THE EQUIPMENT IS INITIALLY DELIVERED.

TO AVOID COMING INTO CONTACT ACCIDENTALLY WITH ANY OF THE

CONNECTOR PINS, BE SURE TO PLACE THE PROTECTIVE CAP OVER THE RECEPTACLE WHENEVER THE TRANSDUCER IS UNPLUGGED.

LOCK THE CAP USING THE TWO SCREWS ATTACHED.

(2) TO COMPLY WITH THE RELEVANT WHEEL–MARK TYPE APPROVAL

REGULATIONS, THE EQUIPMENT MUST BE OPERATED USING ONE OF THE TRANSDUCERS SPECIFIED IN THIS MANUAL. OPERATION WITH A TRANSDUCER OTHER THAN A SPECIFIED ONE IS NOT OFFICIALLY APPROVED, AND THE RESULTS OBTAINED WITH SUCH A TRANSDUCER MUST NOT BE USED FOR NAVIGATIONAL PURPOSES.

(3) THE ACCURACY OF THE ON–SCREEN DEPTH READOUT IS

AFFECTED BY WATER TEMPERATURE, SALINITY, DEPTH AND OTHER UNDERWATER CONDITIONS AS WELL AS THE SHIP’S ROLL AND PITCH, HEEL AND TRIM.

TAKE THESE POSSIBLE ERROR–CAUSING FACTORS INTO

CONSIDERATION WHEN USING THE DEPTH READOUT, SUCH AS WHEN NAVIGATING SHALLOW AREAS OR IN APPLICATIONS WHERE ACCURATE DEPTH READING IS CRITICAL.

(4) DURING SHALLOW WATER OPERATION, THE EQUIPMENT MAY

OCCASIONALLY READ TWICE THE ACTUAL DEPTH BY LOCKING

ONTO THE *

SECOND BOTTOM ECHO.

THE DIGITAL DEPTH READOUT SHOULD ALWAYS BE COMPARED

WITH THE GRAPHIC BOTTOM INDICATION OR WITH SOUNDINGS DATA IN OFFICIAL NAUTICAL CHARTS TO DETERMINE THE TRUE DEPTH.

TOTAL RELIANCE ON THE DIGITAL READOUT ALONE FOR DEPTH

INFORMATION IS DANGEROUS AND MUST BE AVOIDED.

See paragraph 7.4.2 for more information on the second bottom echo.

GENERAL SAFETY WARNINGS

CVR-010

General Safety Warnings – 2/2

(5) WITH A TRANSDUCER DRAFT ENTERED, THE ON–SCREEN DIGITAL

READOUT SHOWS THE DEPTH FROM THE WATERLINE AND NOT FROM THE TRANSDUCER FACE OR FROM THE SHIP’S KEEL.

GREAT CARE SHOULD, THEREFORE, BE TAKEN IN USING THE

DEPTH READOUT WHEN NAVIGATING SHAL LOW WATER AREAS. BE SURE TO SET THE DEPTH REFERENCE TO “BELOW SURFACE” (DBS) TO AVOID ANY MISUNDERSTANDING.

See paragraph 8.2 for more information on transducer draft.

(6) WHEN THE DEPTH REFERENCE INDICATION IS SET TO “BELOW

KEEL,” BE SURE TO ENTER THE APPROPRIATE KEEL OFFSET TO A VOID ANY MISUNDERST ANDING ABOUT THE DEPTH READOUT.

See paragraph 8.10.7.3 for more information on keel offset.

(7) DO NOT SWITCH THE EQUIPMENT ON WITH THE TRANSDUCER

OUT OF WATER, SUCH AS WHILE THE VESSEL IS DRY–DOCKED, OR THE TRANSDUCER’S CERAMIC CRYSTALS MAY BE DAMAGED IRREPARABLY.

(8) THE DISPLAY CABINET IS NOT WEATHERIZED FOR OUTDOOR

INSTALLATION OR OPERATION. ANY DAMAGE CAUSED, WHETHER DIRECTLY OR INDIRECTLY, THROUGH WATER INGRESSION IS NOT COVERED BY THE MANUFACTURER’S OR DEALER’S WARRANTY.

(9) NEITHER THE MANUFACTURER NOR ITS DEALER IS LIABLE

FOR LOSS OF LIFE, BODILY INJURY OR DAMAGE TO THE PROPERTY ARISING FROM THE USE OF THIS EQUIPMENT OR FROM BEING UNABLE, FOR ANY REASON, TO OPERATE THIS EQUIPMENT.

< CAUTION >

Environmental Safety – Equipment Disposal

The display cabinet and the transducer are considered environmentally safe in their original, assembled forms. However, if either unit is to be discarded for any reason, ensure full compliance with all pertinent national/local regulations/ordinances, and contact your dealer or the manufacturer for assistance or instructions before disposing of it.

Product Description

CVR-010

5. Product Description

The Model CVR–010 is a single–channel navigation echo sounder designed to comply fully with IMO Resolution MSC.74( 69) Annex 4, and is type–approved by BSH on the basis of compliance with the DIN EN ISO 9875 standards and pertinent IEC requirements for wheel mark certification.

Featuring a 5.7–inch daylight–viewing, LED–backlit color TFT LCD screen, the equipment displays the echogram using a total of seven user–definable ease–on–the–eye analog strength–level colors that represent various layers of the bottom stratum. The display can be set to show the bottom contour alone in a single color via a menu–guided procedure.

Digital depth readout is also available using easy–to–read large fonts with a clear on–screen indication of the reference of measurement (from the waterline, the transducer or the keel), and in meters, fathoms or feet. To comply with the IMO resolution, the depth reading must be indicated in meters for navigational purposes.

With an optional GPS sensor plugged in or an onboard GPS data source connected, the ship’s LAT/ LON coordinates, speed and heading data will also be displayed at the same time.

A battery–backed realtime calendar clock is built in to indicate the date and time in UTC or in the desired local time at all times. With an appropriate GPS sensor plugged in, the time is automatically referenced to the atomic–precision GPS time.

Up to 12 hours of sounding data will be stored in non–volatile memory at approximately two–second intervals, together with associated date and time, range in use plus position coordinates (with an optional GPS sensor plugged in or a GPS source connected).

The user can review the stored data across any 15–minute segment at any point in time over the past 12 hours through a specially designed window easily accessible with a devoted key.

The depth sounding history can be graphically displayed to show how the depth varied over the past hours. Detailed data is also available digitally via another window that can also be accessed with a single keystroke.

The data can be output on demand in NMEA–0183 (IEC 61162 – 1 )–compatible format via rear panel interface connectors for use in shore–based applications, and is protected against a system reset.

An easy–to–use menu system is incorporated to set the transducer draft, depth reference, echo threshold level, echo display mode, etc. in addition to operating parameters to be selected mainly at installation time.

Unauthorized access to the menu system can be prevented with password entry, if desired. For use with the CVR–010, high quality TOKIN 50 and 200 kHz transducers are

BSH–approved. A desired frequency should be specified at the time of ordering so that a matched transceiver board is installed before shipping.

Both the receiver gain and TVG (anti–clutter) levels are automatically controlled for hands– free operation when the equipment is operating in the fully automatic mode (AUTO). Manual override of both functions is also possible. Interference from other echo sounders operating in the vicinity can be effectively eliminated or reduced with a 3–step noise reduction function.

The acquired data will also be output via the rear panel RS–422 connectors simultaneously for use in other onboard applications requiring depth, date/time and position information.

The built–in alarms include depth alarm, bottom–missing alarm, power failure (low voltage) alarm and power removal/shutoff alarm.

(continued on next page)

Page 17

Product Description

CVR-010

5. Product Description

(continued – 2/2 )

The depth alarm alerts the operator to decreasing depth ( shallow alarm). A variable depth marker can be turned on to set the alarm depth graphically as well as digitally.

The bottom–missing alarm warns against the bottom echo being lost, becoming too weak or exceeding the current range limit.

The power failure (low voltage) alarm will be activated if the power line voltage drops below the factory–specified predetermined level.

The power removal/shutoff alarm will be triggered in the event power is accidentally removed or shut off at the ship’s power source with the equipment operating, emitting continuously a repeating beep for several minutes.

The alarm activation status, except for the power removal/shutoff alarm, will be indicated both audibly and visually, and the alarm on/off switched outputs will be separately available for driving externally connected alarm indicating devices through a devoted connector.

For use with onboard INS applications, the equipment outputs the NMEA–0183 (IEC 61162–1)–formatted alarm sentence for each alarm via one of the rear panel RS–422 ports at specified intervals. When any of the alarms becomes active, the output’s status and intervals will be changed accordingly, and an active alarm can be remotely acknowledged and reset with an appropriate software command from an INS terminal or with a suitable hardware on/off switch mounted at a different location.

The display cabinet has a rugged DC power supply built in that assures reliable operation against a wide range of voltage fluctuations. In an installation where an AC power source is available, the equipment can be operated primarily from the AC source through an optional Model AC–2000 AC adapter for an automatic changeover to the DC power source in the event of AC power outage.

① Bottom Echo

The bottom echo is shown in up to a total of seven different colors, depending on the

strength. The colors used to display the echoes are shown on the color scale (

②

) in order of strength. Red, initially at the lower end of the scale, represents the strongest part of the echo ( i.e. hardest layer of bottom stratum), and blue initially represents the weakest part (i.e. softest layer of the bottom). It is possible to display only the contour

of the bottom in a single color via the menu–guided procedure. See paragraph 8.9 for instructions.

② Color Scale

When the

echo display is set to show echoes in full colors, the colors used to display various echo strength levels are listed here in order of relative strength. The color that represents the strongest level is initially red, and the one that represents the weakest level is initially blue. The intervening colors simulate various mid strength levels. See paragraph 8.10.2 for related information.

An echo must be initially 3 decibels (dB) stronger or weaker than the adjace nt strength

level before it can be displayed in next stronger or weaker color. See paragraph 8.10.4 for greater details.

switch it back to “AUTO.” The figure below illustrates an example of how depth range selection occurs with this mode

activated, as you travel over a gradually deepening bottom. As soon as the bottom shows up at the lower end of the scale lines on the current depth range, the next greater range will be automatically selected. When traveling over a gradually shallowing bottom, the range selection sequence is reversed. As soon as the bottom is registered in the upper half screen, the next smaller range will be switched in.

TVG: Time–varied gain. This function, which sharply reduces the receiver gain at the start of each sounding and

gradually recovers the normal gain level with time, is used to prevent surface clutters and other noise–producing reflections near the surface from disturbing depth measuring operation.

7.4. Interpreting Echo Display

7.4.1. Bottom Echo in Full Colors

The equipment normally shows only the strongest part of the bottom echo in a single color (initially red).

Echoes including the bottom reflection can however be displayed in up to a total of seven different colors – initially, red, orange, yellow, green, yellowish green, light blue and blue, which represent the various layers of the bottom stratum in order of strength – via the

procedure given in paragraph 8.9; namely, red represents the strongest level, and blue,

the weakest one. A colored bar (termed “ color scale” in this manual) located at the left end of the screen

indicates the colors that are currently assigned to display echoes, as in the illustration below.

MAIN MENU→8:ECHO DISPL AY→ 2:NORMAL DISPLAY

Figure 7-17 Initial Assignments of Bottom Echo Colors

Initial Color Assignments

Blue (weakest)

Light Blue Yellowish Green Green Yellow

Orange Red (strongest)

Figure 7-18 Initial Echo Dynamic Range

You can change those color assignments by selecting from a total of 10 different colors provided. See paragraph 8.10.2 for instructions.

There is initially an approximately 3 dB difference in strength between two adjacent colors, as illustrated in the figure at right, meaning that a particular color is approx. 1.4 times stronger or weaker than either adjacent color. This difference, called the echo dynamic range, can be changed to suit various bottom conditions (hard, soft, muddy, etc.). See paragraph 8.10.4 for instructions.

CVR-010

7.4.2. Multiple Bottom Echoes

When navigating a shallow water area, you may observe a bottom–like echo at twice the present depth, and sometimes also at three or four times the depth. This multiple echo phenomenon occurs when the first echo is reflected back and forth a number of times between the water surface and the bottom like reverberations.

In the case of the example below, a first reflection, which is used to register the depth, is bounced back to the bottom, and then back again to the transducer as a second reflection, thereby causing that echo to be recorded at twice the depth.

The appearance of multiple bottom echoes indicates that the bottom is relatively hard.

Figure 7-19 Display of Multiple Bottom Echoes – Example

1st Reflection

2nd Reflection

The effect of multiple reflections may be reduced by decreasing the receiver gain (through gain and / or TVG adjustment, paragraphs 7.5 and 7.6) when you are operating the unit in

manual control (MANUAL) mode. Occasionally a large school of fish or a temperature

the layer can also cause the equipment to lock onto it, thus producing an incorrect digital depth readout.

switches the control between automatic mode and manual mode. When the unit is in the automatic



Whenever you have any doubt about the validity of digital depth reading, check the depth graphically against the on–screen scale calibrations to determine whether the current digital readout is valid or not.

A special caution should be exercised when using digital depth information while in shallow water operation because the second echo may be tracked for depth measurement, resulting in a digital readout twice the actual depth.

Page 38

Basic Operating Instructions

CVR-010

7.4.3. Other Echoes

When the

echoes from fish schools, temperature layers, and various tiny objects, like plankton

echo display is set to show echoes in full colors, the equipment will show

concentrations and air bubbles, in addition to the bottom echo. The figure below is an example of how such echoes show up on the screen. A thick line appearing in the strongest echo color at the upper edge of the echo display area is called a zero line, which is caused by a portion of transmitted energy leaking into the receiver, and represents the on–screen position of the transducer. When a transducer draft is entered ( paragraph 8.2 ), the zero line shifts down from the top scale calibration ( scale 0) by the amount of the draft. When a keel offset is entered (paragraph 8.10.7.3), the zero line occurs above scale 0, and its display is suppressed.

Paragraph 8.9. (MAIN MENU→8:ECHO DISPLAY→2:NORMAL DISPLAY)

Those echoes are mostly suppressed by TVG with the unit in the automatic control mode.

BE SURE TO CONFIRM THE READOUT BY COMPARING IT WITH ON–SCREEN BOTTOM ECHO LOCATION. TOTAL RELIANCE ON THE DIGITAL DISPLAY IS DANGEROUS AND MUST BE AVOIDED, ESPECIALLY WHEN TRAVELING IN SHALLOW AREAS.

2. WHEN TRAVELING OVER A SHALLOW BOTTOM, THE EQUIPMENT MAY

The following settings that affect the way the equipment operates can be made via a menu system consisting of a main menu (MAIN MENU) and a number of associated submenus accessible through main menu options:

・ settings that you do not have to change frequently , such as the transducer draft and echo

threshold level.

・ settings that should be made mainly at initial installation time, such as depth readout unit,

keel offset and local time offset.

To activate the menu system, simply press

8.2. Entering Transducer Draft

8.2.1. Introduction

The transducer draft used in this manual refers to the depth from the water surface to the transducer face, as defined in Figure 8–2. The de pth readout shown on the screen initially represents the depth to the bottom, measured from the transducer face (depth below transducer or DBT). If you wish to read depths from the waterline (to agree with spot soundings or bathymetric data on official charts), you have to add the draft to the on–screen depth readout. The following procedure will allow you to enter the desired draft in 0.1–unit steps (0.1–meter/fathom/foot steps) so that both digital depth readout and graphical indication reflect the draft, automatically reading depth from the waterline.

< WARNING >

WITH A TRANSDUCER DRAFT ENTERED, THE ON–SCREEN DIGITAL READOUT SHOWS THE DEPTH FROM THE WATERLINE AND NOT FROM THE KEEL. GREAT CARE SHOULD, THEREFORE, BE T AKEN IN USING DEPTH DATA WHEN NAVIGATING SHALLOW WATER AREAS.

NOTE: To read depth from the keel, you must first register the keel offset (distance from the transducer face to the keel). Refer to paragraph 8.10.7.3 for details.

8.4. Echo Threshold Adjustment

8.4.1. Introduction

When the

echo display is set to show echoes in full colors, echoes including the bottom reflection are shown in up to seven different colors depending on their relative strengths. The color scale at the left edge on the echogram screen shows the colors that are used to indicate echo strengths, with the bottom–end color ( initially red) representing the strongest echo and the top–end color ( i nitially blue), the weakest echo. Echo threshold adjustment consists of suppressing the display of weak color echoes, such as surface clutters, allowing only strong echoes to show up on the screen without decreasing the receiver gain. The three strongest echo col ors (initially, red, orange and yellow) cannot be suppressed.

8.13. Selecting Depth Readout Response Times

8.13.1. Introduction

The equipment sometimes fails to receive a solid bottom signal due to turbulence or a layer of bubbles covering the transducer or when traveling over a precipitously sloping bottom that returns the echo to directions other than the transducer. If the lost–bottom condition occurs only briefly, the equipment will hold

* the last measured depth readout until the echo is

recovered. However, if such a condition continues in excess of a certain period of time, the echo sounder will reset the last data, starting to search for the bottom by switching the depth ranges one by one, the smallest range first. During that period, no depth readout will be available. This bottom searching operation can take up to approx. 30 seconds at a time.

If you wish to see the change in depth more quickly when navigating areas where the bottom structure varies sharply over short distances, select shorter time periods (depth readout response times) during which the equipment holds the last depth value, via the following steps.

10. Outputting Stored Data for PC–based Applications

10.1. Introduction

V arious types of data stored in non–volatile memory can be output via rear panel connectors (RS–422–A/B and I/O data ports) for processing or analysis in PC–based applications. The soundings information retrieved from memory is in meters and in NMEA–0183 DPT format ( consisting of depth–below–transducer, draft and keel offset), regardless of whether oth er readout unit (FM or FT) is selected via the procedure in paragraph 8.10.3, and the date /time information is in UTC even if a local time offset was entered. The echo sounder functions are disabled while the stored data are being uploaded to a PC or other host system, thereby preventing the saved data from being altered or updated.

10.2. Data Output Format

The data sets are output with the latest one first, and in the manufacturer’s proprietary format complying with IEC 61162–1/NMEA–0183 data sentence specifications, as detailed below:

12. User–Level Maintenance Instructions

To ensure long–term trouble–free operation, the user should regularly follow the maintenance instructions described in this section.

12.1. Maintenance on the Equipment Cabinet

Keep the equipment away from sea splashes, direct sunlight and other heat–generating sources, and make sure that air around the cabinet is circulating freely. If the equipment is not going to be used for prolonged periods of time, dismount the cabinet from the vessel and place it in dry storage. Be sure to switch the equipment off before removing electrical

connections from the rear panel.

< WARNING >

CHEMICAL SOLVENTS, SUCH AS PAINT THINNERS AND BENZENES, MUST NOT BE USED TO CLEAN THE CABINET OR SCREEN FILTER, OR PERMANENT DAMAGE TO THOSE PARTS WILL RESULT.

To clean the cabinet surface, a neutral–type household detergent intended for office equipment is recommended.

Cleaning the acrylic filter on the LCD screen should be a maintenance routine to avoid using a high brightness level. To clean the screen filter, use a piece of slightly wet cloth. If stains persist, the cloth may be moistened with a neutral type detergent.

12.2. Maintenance on Electrical Connections

The high humidity marine environment can cause electrical contacts in the rear panel connectors to corrode over time. Vibrations and shocks normally encountered on the vessel in motion can cause the electrical contacts to become loosened. Corroded or loose contacts will become responsible for erratic, intermittent operation or poor performance. To avoid such possible problems, conduct the following maintenance operations at least once a year:

● Unplug all the cables from the rear panel, and check to be sure that contact surfaces,

including the pins in the rear–panel mounted receptacles are free from corrosion.

● Check the connections at the power source for freedom from any sort of corrosion.

● Correct any problem using a high quality contact–cleaning agent (contact rejuvenator).

< WARNING >

SANDPAPER WILL DAMAGE THE CONTACT SURFACE AND MUST NOT BE USED.

12.3. Maintenance on The Transducer

Marine growth on the transducer face will cause the sensitivity (ability to detect weak echoes) to drop over time. Whenever there is an opportunity to access the installed transducer, check for any growth of barnacles or weed on the face. Carefully remove such growth using a piece of wood or sandpaper, taking care not to score the face material.

< CAUTION >

Painting the transducer face will degrade the sensitivity.

12.4. Servicing the Equipment

If the equipment shows any sign of malfunction, contact your dealer for assistance. High voltages are present inside the equipment cabinet. Do not open the cabinet in an attempt to correct the problem. There are no user–serviceable parts inside.

Page 81

User-Level Maintenance

12.5. Temporary Display of A–Scope

The A–scope is a format of echo presentation, showing various echo strength levels in the form of horizontal deflections, as well as in colors.

This function is provided mainly for ease of performance checks, maintenance or alignment by authorized service engineers and can be activated via the following keystrokes:

CVR-010

① Turn the equipment off.

② Turn it on again while holding down the combination of

Figure 12-1 Typical Echogram Screen with A–Scope Turned on

An example display is shown at right. The size of deflection represents a relative strength level, i.e. the greater the deflection, the stronger the echo. The display will remain for approx. 5 minutes and will then be turned off automatically.

The A–scope display will help estimate instantly an approximate size of an object as soon as it is detected, thereby eliminating the need to wait for the whole block of echoes to become visible across the screen when operating on deep ranges or at slow echogram feed rates.

To turn it off quickly, shut down the unit.

13. Installation Instructions

13.1. Display Cabinet Installation

13.1.1. General Precautions

The display cabinet is constructed to withstand the humid and corrosive marine environment, but is designed to be installed or operated inside the wheelhouse or chartroom. Serious damage will result to the electronics inside the cabinet when it is exposed to salt water spray or splash.

Additional Requirements For long term trouble–free service, the proposed site for installation should be:

・ dry, well–ventilated and free as much as possible from shocks and engine vibrations. ・ away as much as possible from high temperature outlets ( such as exhaust fans and

heaters ), and as much as possible from areas where the unit is likely to be constantly exposed to direct sunlight.

13.1.2. Mounting

13.1.2.1. Mounting the Cabinet The display cabinet is primarily designed to be mounted on a tabletop with the mounting

bracket supplied and weights approximately 2.2 kg in total. The dimensions necessary for installation are given in Figure 13–1. Provide sufficient clearance behind the cabinet for cabling termination and maintenance checks.

Using a total of five appropriate wood screws or bolt/nut combinations through its four mounting holes (7 mm in diameter each), secure the bracket to the selected site.

Make sure that the mounting surface is strong enough to support the unit against shocks or vibrations that are likely to be encountered with the ship in motion.

< WARNINGS >

1. EXTREMELY HIGH VOLTAGE PULSES ARE PRESENT ON THE PINS IN THE REAR–PANEL TRANSDUCER CONNECTOR WITH THE EQUIPMENT SWITCHED ON. TO PREVENT AN ACCIDENTAL CONTACT WITH ANY OF THOSE PINS WHENEVER THE TRANSDUCER IS UNPLUGGED, THE CONNECTOR MUST BE COVERED W IT H THE PROTECTIVE CAP SUPPLIED. BE SURE TO LOCK THE CAP WITH THE TWO SCREWS ATTACHED.

2. DO NOT PLACE THE UNIT IN AN UNVENTILATED, SEALED ENCLOSURE,

SUCH AS A THEFT–DETERRENT CABINET, OR OVERHEATING AND MALFUNCTION WILL RESULT.

3. DAMAGE CAUSED BY EXPOSURE TO WATER SPRAY OR TO DIRECT

SUNLIGHT WILL NOT BE COVERED BY THE MANUFACTURER’S WARRANTY.

Be sure to attach a serrated plastic washer to the inside of each arm before placing the cabinet in the bracket. This pair of washers is supplied separately in the plastic bag that contains the power cable, fuses, plugs, etc., and prevents the cabinet from leaning forward or backward with the clamping knobs tightened.

After tilting the cabinet to a desired viewing angle, tighten the clamping knob firmly.

13.2. Transducer Installation

13.2.1. General Precautions

The installation should be planned in advance, keeping in mind the standard cable length integrally connected to the transducer. In an installation where a longer cable is required, it is recommended that the transducer be ordered with the desired cable length instead of extending the existing cable with an additional cable. If the existing cable has to be extended, be sure to use the same type of cable supplied by the manufacturer.

< WARNINGS >

1. DO NOT LIFT THE TRANSDUCER BY HOLDING ITS CABLE OR THE INTERNAL CABLE WIRING WILL BE DAMAGED DUE TO ITS WEIGHT.

2. THE TRANSDUCER IS A DELICATE PIECE OF ELECTRONICS, AND MUST NOT BE HIT, DROPPED OR HANDLED ROUGHLY. DAMAGE TO THE TRANSDUCER FACE CAN RESULT IN SERIOUS PERFORMANCE DEGRADATION.

< CAUTION >

Use of extension cable not approved by the manufacturer will seriously degrade the transducer per formance. Coaxial cables cannot be used.

13.2.2. Choosing Installation Location

The transducer location and method of installation will greatly affect the bottom detecting capability of any echo sounding equipment. Careful consideration must be given to selecting the mounting location and deciding the method of installation that best suit the vessel.

Air bubbles and turbulent streams generated by the vessel in motion will most seriously degrade the bottom tracking performance. Each transducer should be located away from, and forward of, the propellers and shafts, well clear of any water intake/discharge line, hull openings, outlets, sea chests, and any other projections along the hull that might disturb the smooth flow of water around the transducers. It is recommended that the transducer be located on the side where the ship’s propellers will move downwards to prevent them from pushing air bubbles up against the hull.

CAUTIONS >

・ Inside–the–hull mounting w ill cause a serious impedance mismatch between the

transducer and the transceiver. The manufacturer will not guarantee depth detection performance, if such a mounting method is employed.

・ Do not paint the transducer face, or performance degradation will result.

Although the appropriate location depends on the type of hull and cruising speeds, a practical choice will be somewhere between 1/3 and 1/2 of the vessel’s length from the fore. A second transducer may be mounted in the aft third of the vessel.

The transducer should be installed on, or close to, the vessel’s centerline. On deep–keeled vessels, care must be taken to ensure that the energy beam (paragraph 13.2.3 ) of the transducer will not be blocked by the keel. If depth from the keel ( DBK) is to be read, be sure to measure, and take a note of, the keel offset (distance from the transducer face to the keel in vertical plane) at this step. See paragraph 8.10.7.3 for related information.

There should be sufficient space inside the hull to allow access to the transducer housing, cable, stuffing tube, etc.

Page 85

Installation Instructions

CVR-010

13.2.3. Matched Transducers

The equipment is designed to operate properly with one of the following BSH–approved transducers:

・ TOKIN TGM60–50 series 50 kHz transducers (600W

RMS, standard: 20m cable)

・ TOKIN TGM80–200 series 200 kHz transducers (600W

RMS standard 20m cable)

The dimensions of those transducers are given in the following page. For installation in a steel–hulled vessel, the user ( or the shipyard) must design and prepare an appropriate housing/blister that may have to be certified by the applicable ship’s classification society or a notified body to comply with the relevant requirements for wheel mark certification.

< WARNINGS >

1. USE OF TRANSDUCER OTHER THAN THE ABOVE IS PROHIBITED UNDER

THE RELEVANT BSH TYPE APPROVAL REGULATIONS, AND CAN RESULT IN EITHER SERIOUS DAMAGE TO THE TRANSDUCER/TRANSCEIVER OR EXTREMELY POOR DEPTH DETECTION PERFORMANCE.

2. DO NOT SWITCH THE EQUIPMENT ON UNTIL THE TRANSDUCER IS

IMMERSED IN WATER, OR DAMAGE TO THE TRANSDUCER CRYSTALS CAN RESULT.

1 3.2.4. Selection of AUTO TVG Response Characteristics for Transducers

13.3.2. Power Supply Connections

13.3.2.1. Power Supply Requirements and Power Cord Routing

The equipment is powered by a DC power source between 11 and 40 volts, floating ground. The ship’s power source must be capable of continuously supplying at least 5A at 12 VDC or 3A at 24 VDC for proper start–up and reliable operation.

To minimize the chance of picking up extraneous electrical interference, it is highly recommended that the power cord be connected direct to the ship’s power source, and not via other terminals or power distribution board that are used in common with other on–board electronics. Ideally, the equipment cabinet should be powered by an independent power supply for best results.

13.3.2.2. Connections

< WARNING >

REVERSING THE POWER CORD POLARITY WILL BLOW THE FUSE THE INSTANT THE CORD IS PLUGGED INTO THE UNIT, EVEN IF IT IS SWITCHED OFF.

The display cabinet, which is electrostatically coated inside, can be grounded to the ship’s earth ground without grounding the negative line of the power source. In situations where it is required, or desirable, to ground the cabinet for safety reasons or from the wing–nut–fitted ground terminal on the rear panel to an appropriate earth ground using a thick wire. The ground wire should be as short as possible to reduce the chance of picking up interference from other electronics.

*EMC compliance, connect

*EMC = electromagnetic compatibility

13.3.3. Connections to Transducer

The transducer is supplied with its integral cable. A three–hole female–type plug is separately supplied for terminating the cable for connection to the equipment cabinet. With the aid of the illustration below, disassemble the plug, taking care not to lose the small screws.

< WARNING >

DO NOT TURN THE EQUIPMENT ON WITH THE TRAN SDUCER PLACED IN THE AIR, OR DAMAGE TO THE TRANSDUCER CRYSTAL WILL RESULT.

Cable Extensions In installations where the existing integral cable must be extended, be sure to use the same

type of cable supplied by the manufacturer. Use of additional cable not approved by the manufacturer will seriously degrade the depth detection performance. All joints must be made by soldering and properly insulated. “Twist–and–tape” connections must be avoided.

Coaxial cables are electricall y unbalanced and cannot be used

Slide the plug shell over the cable first, and solder the conductors to the three pins on

the plug body as follows:
