As main causes, the following can be stated: − Propeller(s) running reversed; − Thruster(s) in operation, especially at low speed ahead; − Engine noise, transferred to the transducer either by the hull structure or through the water, the latter especially as bottom- reflection in shallow water. − Losing sonar contact with the water at extremely bad weather, as a result of violent pitching. − Hot water discharges from power plants; − Rising cold water in several sea areas. The list above is not complete; we will be pleased to assist with further information on request, see also chapter 5.1 Installation. The LAZ 5100 echosounder has been built in accordance with state of the art standards and recognised safety regulations. Nevertheless, it may constitute a risk to life or limb of the user and or third parties, or cause damage to the vessel and or other material property if the following rules are not complied with. The LAZ 5100 Echosounder must only be used in a technically flawless condition in accordance with it's designated use and the instructions contained within this Technical Handbook and only by safety conscious persons who are fully aware of the risks involved in operating such a system. The LAZ 5100 Echosounder is designed exclusively for use as a navigational echosounder. Using the system for purposes other than this is considered contrary to it's designated use. The manufacturer can not be held responsible for any damage resulting from such misuse. The risk of such misuse lies entirely with the user. Personnel entrusted with operating the system must have read the Technical Handbook, in particular the section on safety measures before and during operation. Reading these instructions after starting the system is too late. This applies especially to persons who only work with the system occasionally, e.g. during setting up or maintenance. Always observe the maintenance/inspection intervals laid down in this Technical Handbook. Use only spare parts authorised by the manufacturer and never replace defective fuses by those of any other rating than specified. Switch the system OFF immediately if trouble occurs with the electrical system. Page 1-1 L-3 ELAC Nautik Work on the system must only be carried out by a qualified technician or a specially trained person working under the supervision of such a technician. Electrical engineering regulations must be observed at all times. Observe all safety instructions and warnings for operating and maintenance attached to the system. Ensure that such safety instructions and warnings are always complete, visible and perfectly legible. Never make any modifications, additions or conversions to the system without the manufacturers full approval. If the system is shut down for maintenance or repair, it must be secured against inadvertent switching ON by isolating the system from the mains power supply and attaching a sign to the front plate of the display and control unit stating that the unit must not be switched ON because maintenance or repair work is being carried out. Always check tighten any screwed connections, e.g. plugs, sockets and terminals, which may have been loosened during maintenance or repair work. Always dispose of replaced parts in accordance with local environmental regulations. Check the system regularly for defective cables, connections etc. Alterations within the SERVICES menu must only be made by trained persons. Altering setting within this menu may lead to incorrect depth readings which in turn may lead to loss of life or limb. Service technicians opening the Display and Control unit for repair purposes must observe the tightening torque of the capped nut and washer, see items 17, 27 in drawing: ECHOLOT LAZ 5100-01 to 10, no. 52 590 8001 to 8010 in chapter 6 "DRAWINGS" . Echosounding Systems and remote indicators which detect and display the water depth from a single momentary value per transmission pulse, e.g. digital and pointer displays, can display false readings over a period of time. This is primarily valid in shallow water areas. For this reason, water depths displayed in this manner must be compared with the graphic presentation at such intervals as to guarantee the ship's safety. Page 1-2 L-3 ELAC Nautik 2 GENERAL INSTALLATION INSTRUCTION FOR ECHOSOUNDERS 2.1 TRANSDUCER INSTALLATION The performance of an echosounder is limited by the acoustical propagation of sound in water. Mainly this is influenced by the transducer mounting place, the operational frequency and the transducer efficiency. The transducer mounting place is to select in such a way, that the transducer surface is free of air bubbles and turbulence. Air bubbles and turbulence will reflect the sound energy so that no echoes from the bottom will return. That's why transducers in general have to be installed in ship's bow. If the ship has a bow thruster, the transducer has to be mounted ahead of it. Otherwise the turbulence caused by the thruster hole will inhibit echosounding operation. While the bow thruster is operating, no echosounding is possible because of the propeller rotation. On ships with bulbs the transducer must be mounted as far ahead as possible. Transducers mounted in ship's aft normally are limited in function during travelling, because this area is very noisy. Due to engine noise, propeller rotation and air bubbles, the transducers are only efficient during low speed travelling. An indication for that is the disappearing of echoes, digital reading will indicate surface reverberation ( 1-1.5 m ) or “?”. While sailing only the front transducer should be used. 2.1.1 CABLE LENGTH, OPERATING FREQUENCY Both the operating frequency and the length of cable between the echosounder and the transducer influence the performance of echosounding. General rules are: At lower frequencies the influence of air bubbles and turbulence decreases, increased depth measurements are possible, energy loss at longer cable length is minimised. Higher frequencies are less sensitive against radiated water noise caused by the ships engine and propeller rotation. Following tables give information about echosounding performance depending on various parameters. Page 2-1 L-3 ELAC Nautik Table of maximum measurable water depth, depending on frequency, transducer type, cable length. Transducer Type Frequency Manufacturer Electrical Power Maximum Cable Length Maximum Waterdepth LSE 132 30 kHz Elac Nautik 450 Watt 600 m 1200 m LSE 297 50 kHz Elac Nautik 250 Watt 400 m 600 m LSE 133 50 kHz Elac Nautik 450 Watt 600 m 1100 m SW 6016 100 kHz STN Atlas 200 Watt 150 m 300 – 350 m LSE 148 100 kHz Elac Nautik 450 Watt 200 m 350 – 400 m LSE 313 200 kHz Elac Nautik 250 Watt 150 m 250 – 300 m LSE 135 200 kHz Elac Nautik 250 Watt 150 m 250 – 300 m The depth values can only be reached with limited cable length and an undisturbed acoustic and electric receiver channel. For cable length longer than mentioned in the table the electrical power of the echosounder has to be increased according to manufacturer's release. Table 1 and 2 show as an example cable loss depending on frequency and cable length and the corresponding possible depth measurements for the frequencies 50 kHz and 100 kHz. Table 1: Cable loss for 100 kHz and 50 kHz Cable length in m 50 100 150 200 250 300 Loss in dB at 100 kHz 1.2 2.8 4.5 6.3 8.2 10 Loss in dB at 50 kHz 0.8 1.7 2.6 3.6 4.6 5.6 Table 2: Depth measuring performance, cable length- dependent for 100 kHz and 50 kHz Cable length in m 50 100 150 200 250 300 Depth in m at 100 kHz 270 250 230 200 180 170 Depth in m at 50 kHz 600 580 560 540 515 495 Page 2-2 L-3 ELAC Nautik 2.1.2 CABLING, CABLE LOCATION, CABLE SPECIFICATION Critical point in cabling is the correct handling of the cable screens, especially for the transducer cable. The cable screens have to be grounded only at one point: at the echosounder. In all connection boxes the screens are slide and not connected to ground. Dismantling has to be as short as possible. The transducer cable from transducer to the first connection box has to be fed through a steel protection pipe. From the first connection box to the echosounder three kinds of cable laying are mandatory recommended: • the cable is laid in a steel pipe • a double-screened cable is used as transducer cable, the inner screen is one-side connected to the echosounder's ground, the outer screen is one-side connected to the ship's ground. • the transducer cable has to be laid separately from other cables in a distance of minimum 0.5 m. Most important is not to lay single shielded cable in the vicinity of other cable. NOTE: in any case shielded cable has to be used over the whole distance from the transducer to the echosounder. All connection boxes must be metallic. 2.1.3 TRANSDUCER CABLE SPECIFICATION The cable from the transducer connection box to the echosounder must be approved marine cable according DIN 89158 or similar, like MGCG 2x1.5. At least the requirement of a resistance <13 Ω/ km and a capacity of < 150 nF/ km must be fulfilled. 2.1.4 INTERFACES Printer interface: Standard CENTRONICS parallel interface, cable length: 5 m max. Serial NMEA input: Input for navigational data and time synchronisation Serial NMEA output: Water depth and additional information, see chapter 3.5. Both serial interfaces are RS 422. Only equipment with RS 422 interfaces can be connected to the echosounder, otherwise the interface electronic gets damaged.

Presentation of the water depth is made on a Liquid Crystal COLOR Display (LCD) as. • depth below the keel (DBK) Logically structured MENUS assist the user when selecting the operating parameters required. Built to the highest standards, it is certified to meet all requirements laid down by the IMO Resolution MSC 74/69: Amendments to Resolution A.224,Annex 4 . Wheelmark-tests are certified by the German authorty BSH (German Hydrographic Institute).. Figure 3-1: LAZ 5100 Display and Control Unit Page 3-1 L-3 ELAC Nautik 3.2 SYSTEM CONFIGURATION NOTE: See also Figure 3-2, System Configuration with Options. The basic system configuration is as follows: • 1 x Display and Control Unit LAZ 5100 • 1 x Connection Box • 1 x Transducer 3.2.1 DISPLAY AND CONTROL UNIT The Display and Control Unit will normally be installed on the bridge, either mounted in a console or bracket mounted to the deckhead or bulkhead. It is made up of a display area and a keypad which is used to alter system parameters and settings. The unit can be a one or two channel unit, working with different transducers on different frequencies, see Technical Data. When used with only one transducer ( see Figure 3-1 ), the display area shows the following: • Water depth • Range scale • Time and Date • Latitude and Longitude (if connected to a Navigation system with a standard NMEA 0183, version 2.0 interface) • Minimum and maximum depth alarm settings (if activated) • A trace of the sea bed • A colour bar representing the signal strength of the echoes With two channels, a vertical split display shows left half channel 2 information, right half channel 1 information. Instead of LAT/ LONG a second water depth indication appears. A built-in ring memory continually stores system data, this allows the user to recall data to the screen, or print out a hard copy of any or all events occurring within the last 24 operating hours (if a printer is connected). Page 3-2 L-3 ELAC Nautik 3.2.2 TRANSDUCER CONNECTION BOX This will usually be installed near the transducer, to allow a defective transducer to be replaced without having to replace the complete cabling to the Display and Control Unit. The connection box must be made of metallic material. 3.2.3 TRANSDUCER The transducer converts electrical energy to sound energy and transmits this towards the sea bed. Sound energy returning from the sea bed, in the form of echoes, is converted into electrical energy by the transducer and fed to the Display and Control Unit for evaluation and presentation. 3.3 OPTIONAL EQUIPMENT The following optional equipment is available to broaden the system capabilities: • Digital Slave Display(s) • Printer • Connection Box • Transducer(s) • Switch box Page 3-3 L-3 ELAC Nautik NAVIGATIONSECHO SOUNDER LAZ 5100 X3 MAINS X1 X2 X4 X5 X6 X7 X8 * NMEA RS 422 RS 232 RS 422 OPTIONAL SWITCH BOX OPTIONAL DAZ 25 OPTIONAL 2nd TRANSDUCER MAINS CONNECTION BOX OPTIONAL DAZ 25 OPTIONAL PRINTER OPTIONAL CONNECTION BOX ** TRANSDUCER Figure 3-2 : System Block Diagram with Options * Operator´s Fitness Check ** Mute- Control, TXD1 for Voyage Data Recorder ( NMEA, RS 422) Page 3-4 L-3 ELAC Nautik 3.3.1 DIGITAL SLAVE DISPLAY(S) These are used to repeat water depth information at other parts of the ship where such information is needed. A total of two Digital Slave Displays can be connected directly to the system. NOTE: Echosounding Systems and remote indicators which detect and display the water depth from a single momentary value per transmission pulse, e.g. digital and pointer displays, can, over a period of time display false readings. This is primarily valid in shallow water areas. For this reason, water depths displayed in this manner must be compared with the graphic presentation at regular intervals in order to guarantee the ship's safety. IMPORTANT NOTE: While crossing steep slopes the echo evaluation might fail. A steady depth display cannot be guarantied in this case. The LAZ depth display will show the last evaluated depth value together with a question mark, longer lasting errors will be indicated by a question mark without any depth value. At the digital slave display "----" will be displayed in this case. 3.3.2 PRINTER A Printer can be connected to give a continuous hard copy of data presented on the display area or to print out a hard copy of events from any time within a previous 24 operating hour period. 3.3.3 CONNECTION BOX The Connection Box is connected up to the Display and Control Unit and provides the following connections: • a 2nd Digital Slave Display • a blanking pulse output • depth alarm relay contacts (potential free) Page 3-5 L-3 ELAC Nautik 3.3.4 TRANSDUCER OPTIONS If a 2 channel module is installed, the system is capable of accommodating two transducers without further modification, e.g. one fore and one aft, one port and one starboard. Information received from either or both transducer(s) can be called up for display. 3.3.5 SWITCH BOX If no 2 channel module is installed, a switch box can be used for the connection of two transducers of the same type (frequency). Echo-information of the transducer selected by the switch box will be shown on the display.

The system will switch ON and assume the parameter settings which were selected when the system was last switched OFF. To switch the system OFF, press and hold the second key from the right, marked "OFF", the system will switch OFF after about 3 to 5 seconds. This is a built-in safety feature to prevent accidental switching OFF. 4.2 BRIEF EXPLANATION OF CONTROLS ESCAPE CURSOR GAIN PRINT RANGE DIM OFF MARKER ON ENTER • CURSOR : The CURSOR keys allow the user to move the cursor within a MENU and alter parameters. The position of the cursor can easily be seen, the word, letter or digit marked by the cursor appears inverse (dark background, light text). Parameters to be altered must first be "marked" by the cursor. • ESCAPE : The ESCAPE key is used to leave a MENU or to abort parameter alterations. • ENTER : The ENTER key is used to call up MENUS and confirm parameter alterations within MENUS. Page 4-1 L-3 ELAC Nautik ESCAPE CURSOR GAIN PRINT RANGE DIM OFF MARKER ON ENTER • GAIN : The GAIN keys are used to alter the system gain, otherwise known as amplification, to achieve a clearer presentation. The system can be operated with either automatic or manual gain control. See chapter 4.4.1. • RANGE : The RANGE keys are used to set the depth range of the system. • DIM : The DIM keys are used to set the display backlighting level to suit the user. ESCAPE CURSOR GAIN PRINT RANGE MARKER DIM OFF ON ENTER • PRINT : The PRINT key is used when the user wishes to make a simultaneous hard copy of the echogram. This is only possible if a printer is connected to the system. • MARKER : When the MARKER key is pressed, a vertical dotted line appears on the screen and moves with the presentation from right to left. At the same time all relevant information is stored in the system's 24 hour memory. This memory stores data from the previous 24 system operating hours. • SYMBOL : The key marked with a loudspeaker symbol is used to acknowledge acoustic depth alarms. Page 4-2 L-3 ELAC Nautik 4.3 DISPLAY AREA 4.3.1 SINGLE CHANNEL DISPLAY The Display Area is used to present the user with all relevant information. The screen is divided into two areas. The lower, main area is used to present an echogram of the scenario beneath the ship. It is provided with a scale and time markings. The range in use is displayed beside the scale markings, at the bottom right of the screen. The time markings appear at 3 minute intervals at the bottom edge of the screen. As explained previously, when MENUS are called up, they will appear at the bottom left-hand side of this area. The smaller strip across the top of the screen provides the user with various system and depth information (see illustration below). m Explanation of information contained in the illustration above (from left to right): TIME : Shows the actual time DATE : Shows the actual date NAV OFF : Flashes to indicate that the Navigation mode is not in use i.e. the user has selected other units, sound velocity or depth mode. When the user returns to the Navigation mode, by selecting NAV Defaults, this window will disappear (see also chapter 4.5.1, NAV-Defaults). If the echosounder is in the two channel mode ( only if the second channel and a second transducer is fitted), NAV - OFF is activated without flashing. LONGITUDE : These windows will display the actual Lat. and LATITUDE : Lon. only if the system is connected up to the ship's navigation system. Printing : This window is usually blank. If the user chooses to make a hard copy of the echogram, by pressing the PRINTER key (a printer must be connected) the word "Printing" will appear here. ALARM : These windows show the depth alarm settings. The upper window shows the minimum depth alarm, the lower window shows the maximum depth alarm. If the alarms are not activated, e.g. Status = OFF, the relevant window(s) will remain blank. If an alarm condition is present, the relevant window will flash Page 4-3 L-3 ELAC Nautik REPLAY : When the user chooses to display information stored over the previous 24 operating hours (using the LOG DATA MENU), the word "REPLAY" will appear here. The large window at the right-hand side of the information area is used to display the actual water depth, the measurement mode, units of measurement. The measurement mode can be either: • Depth Below the Keel = DBK (as shown) • Depth Below the Surface = DBS • Depth Below the Transducer = DBT The units of measurement can be either: • Metres = m (as shown) • Feet = ft • Fathoms = ftm If instead of the depth value a ? appears, make sure, that the echo signal will be in the range selected. IMPORTANT NOTE: While crossing steep slopes the echo evaluation might fail. A steady depth display cannot be guarantied in this case. The LAZ depth display will show the last evaluated depth value together with a question mark, longer lasting errors will be indicated by a question mark without any depth value. At the digital slave display "----" will be displayed in this case. Page 4-4 L-3 ELAC Nautik 4.3.2 2 CHANNEL DISPLAY In the 2 channel mode information of the transducer location and frequency of the transducer in use is added. If the presentation channel 1/2 is selected, Information of both channels are shown in a vertical split display. The indication NAV OFF is activated without flashing to indicate, that all parameters are mode of presentation is non standard. For each transducer depth location and frequency is shown. For transducer location and frequency see chapter 5.1.2 Initial System Set - up. m m 10 10 20 20 20 20 40 40 Page 4-5 L-3 ELAC Nautik 4.3.3 WARNING FIELDS Three warning fields are provided on the display: • NAV OFF flashing indicates that one or more parameters do not correspond to the navigational mode, i.e. the user has selected other units, sound velocity or depth mode. • NAV OFF whithout flashing appears in the 2 channel mode. It is a hint, that in this display mode the user has to observe, that for instances dedicated digital slave repeaters are in use. • POWER ERROR occurs when the supply voltage of the echosounder unit undergoes a value of 100 V AC. This is an internal alarm, the POWER ERROR field flashes and an acoustic alarm ( with mute control ) is activated. Page 4-6 L-3 ELAC Nautik 4.4 ALTERING SYSTEM PARAMETERS AND SETTINGS When the system is switched OFF, parameters selected are stored in the system's memory. When the system is switched ON again, these parameters will be retrieved and used (see NOTE below). NOTE: 4.4.1 The "DIM" setting is not stored, a pre-set default setting is used when the system is switched ON. With two channel systems, channel 1 is the default channel at start-up. GAIN, RANGE AND DIM SETTINGS GAIN (amplification), RANGE (depth range) and DIM (display area backlighting and keypad illumination) settings are made by pressing the relevant keys. There are two keys for each setting, one marked with an arrow pointing upwards and one marked with an arrow pointing downwards. Pressing these keys as described below will alter the present setting. The new setting will appear briefly on the display area directly above the key which was pressed and the effects of a change can be observed directly on the display area. Pressing the key a second time will alter the setting by a further unit. GAIN: The unit is fitted with an automatic gain control circuit for the data processing which is always activated when the unit is switched on. The GAIN setting only influences the displayed echo information. The GAIN value can be altered between 1 and 10, whereby 1 is the lowest and 10 the highest gain (amplification) factor. If the sea bed trace appears too weak, the GAIN level must be increased to give a clear presentation. If there is a lot of "noise" to be seen on the display area, the GAIN level must be decreased. To increase the GAIN level, press the GAIN key V To decrease the GAIN level, press the GAIN key W. The value set will appear on the display area above the key (between 1 and 10). Pressing the same key a second time will cause the value to increase or decrease by one further unit. Repeat the procedure until a satisfactory sea bed trace is achieved. In some cases it can be useful to work with manual instead of automatic gain. Manual gain setting is explained in chapter 4.5.2. Page 4-7 L-3 ELAC Nautik RANGE: The RANGE can be set to suit the circumstances e.g. if a water depth of 35 m is indicated, the 50m range will give a better resolution and accuracy than the 200 m range. The range can be altered in the same way as the gain, except that here, pressing the RANGE key V will decrease the range and pressing the RANGE key W will increase the range. There are 6 ranges to choose from, 10, 20, 50, 200, 500 and 2000 m (or the equivalent in fathoms or feet). Selecting the unit of measurement is described in chapter 4.5.2. Increasing the range to more than 2000 m scale an "A" will appear together with the 200 m scale. "A" indicates the selection of the automaticc mode. When the water depth decreases the range will at depth less than 50 m switch automatically in the 50 m range scale, if the depth increases, the 200 m range will be selected. Pressing in the automatic mode the range keys, manual control is activated. NOTE: When DBS is used, the ranges 0-10 m; 0-20 m are not available, only 0-50 m. DIM: The display backlighting can be set in 10 steps to suit the ambient light. To increase the display backlighting, press the DIM key V. To decrease the display backlighting, press the DIM key W (see NOTE below). All other parameters and settings are altered within so called MENUS, as described in chapters 4.4.2 and 4.5. Page 4-8 L-3 ELAC Nautik 4.4.2 GENERAL INFORMATION REGARDING MENUS The ENTER key is used to call up the various MENUS in sequence. The order in which they appear is as follows: • Press the ENTER key 1x - ALARM MENU • Press the ENTER key 2x - PARAMETER MENU • Press the ENTER key 3x - LOG DATA MENU • Press the ENTER key 4x - SYSTEM SET-UP MENU If the ENTER key is pressed 5x, the ALARM MENU will re-appear. When a MENU is called up, the title will be highlighted i.e. it will appear in inverse text, this means light text on a dark background or vice versa, depending upon the DIM setting. During daylight use, the text will be light on a dark background and during darkness, when the screen is dimmed, the text will be dark on a light background. When the title line of a MENU is highlighted, it is possible to leave that MENU by pressing the ESCAPE key 1x, or to change to another MENU by pressing the ENTER key 1x or more until the desired MENU appears. If parameters or settings have been altered within a MENU, the ESCAPE key may have to be pressed more than 1x in order to either return to the title line or to leave the MENU completely. The ESCAPE key can also be used to abort parameter selections. A detailed example of altering system settings and parameters within a MENU can be seen in chapter 4.4.3. It is advisable that the user reads this Section thoroughly and practices making the alterations described in order to become more familiar with the system. WARNING: Do not alter parameters within the SERVICE SUB-MENU unless authorised to do so. See also WARNING given in chapter 4.5.4, "The SYSTEM SET-UP MENU". Page 4-9 L-3 ELAC Nautik 4.4.3 ALTERING SYSTEM SETTINGS/PARAMETERS WITHIN A MENU When a MENU is called up, it will appear at the bottom left-hand side of the display area. There are 4 main MENUS available. These can be called up by pressing the ENTER key.

Finely adjust the desired time by pressing the CURSOR V or W key momentarily, each time a key is pressed, the time will advance by a 5 second period. If the event to be viewed occurred a lot earlier, scrolling can be accelerated by using the "Page scroll" option. Press the ENTER key and the word "Page" will appear in the window beneath the "Depth Alarm" window. When the CURSOR V or W keys are now pressed momentarily, the display will be shifted by approx. three quarters of a page backwards or forwards (pressing and holding these keys scrolls continuously). EXAMPLE: To view data at the time "Marker line a" was set, press and hold the CURSOR W key until the marker line is almost at the right-hand side of the display area. Finely adjust by pressing the CURSOR W repeatedly until the marker is at the extreme right-hand side of the display area. The data will now be presented in the upper part of the display area. To move "Marker line b", press the ENTER key. The word "Page" will appear in the window below the alarm window showing that the "Page scroll" option is activated. When the CURSOR W is now pressed once, the marker line will jump to the right. Press the ENTER key to return to the "slow scroll" option and finely adjust as previously described for "Marker line a". NOTE: Depth, scale and position information will not be updated during scrolling (only time and echograms) except when a marker line passes the right-hand border of the display area. The following information can be read off the display area for any given time during the previous 24 system operating hours: • Water depth at that time • Units and mode of measurement at that time • Range in use at that time • Time and date at which the information was stored • Whether the NAVIGATION mode was in use at that time • Latitude and Longitude at which the information was stored (if connected to a nav. system) • Whether a shallow water alarm was activated at that time Page 4-24 L-3 ELAC Nautik Printing data from the memory In order to make a print-out of all or part of the data stored in the memory, so called "limit markers" must be set. Only data within these limit markers will be printed out. To set these limit markers and print the data within them, proceed as follows: • Scroll the display area until one limit is reached (the time can be seen in the "time window"). • Press the MARKER key (the time of the right hand side of the display appears in a window below the depth alarm window) • Scroll the display area until the other limit is reached (the time can be seen in the "time window"). • Press the PRINT key, the time in the window below the depth alarm window will be replaced by the word "Wait", followed after a short time by the word "Printing". During printing, the user may scroll further within the memory. The print-out can be stopped at any point by pressing the PRINT key for a second time. Fault conditions When the PRINT key is pressed, a fault condition may exist. If so, one of the 3 fault conditions shown below will be indicated in the window beneath the depth alarm window: • PERIOD? : This indicates that the user has set the both limit markers to the same time. The limit markers must be set to different times. • PAPER OUT : The printer has run out of paper • ERROR : The printer is not connected, not switched ON, or otherwise defective Making a hard copy of the screen In order to make a hard copy of data displayed on the screen, scroll to the desired position and press the PRINT key. A window will appear containing the word "Hardcopy". The print-out will be an exact reproduction of the screen at the time the PRINT key was pressed. NOTE: With the exception of the PRINT and ESCAPE push-buttons, all other controls are "dead" during the time it takes to print out a hard copy of the screen. The PRINT push-button will stop the printing process and the ESCAPE pushbutton will exit the LOG-DATA feature and return the system to Echosounding operation.

Page 4-28 L-3 ELAC Nautik 5 INSTALLATION, CARE AND MAINTENANCE 5.1 INSTALLATION The display and control unit can be panel, bulkhead, deckhead or console mounted. The system is delivered with mounting brackets as specified by the user. Install the display and control unit in accordance with the relevant section of the Installation Drawing Number EZ 52 590 8001 to 8010 which can be found in chapter 6 "DRAWINGS" of this handbook. The mounting place should assure, that no direct sun light influences the visibility of the display and for clear display readings a viewing angle of ± 50° perpendicular to the display is recommended. The echosounder performance is limited by the acoustic in-water characteristics. These are mainly influenced by the transducer mounting position, the operating frequency and the efficiency of electrical-acoustical conversion. The transducer position must be selected in a way that the radiating surface is mounted in an area virtually free of turbulence and air bubbles. The sound waves are reflected by any layers of air bubbles or turbulence that strong, that the sound can not pass the layers and thus echosounding is prevented. Because of this fact the transducers should be mounted within the ship's bow area. In case of an existing bow thruster, the transducer must be mounted ahead or below the thruster outlet. If mounted behind the bow thruster, the performance of the echosounder will be degraded by turbulence and air bubbles. Even a total echosounding break down is possible. During bow thruster operation echosounding is not possible because a wide area around the thruster´s outlet is saturated with turbulence and air bubbles. On ships equipped with a bulb bow the transducer must be mounted ahead as far as possible, because the bulb generates a layer of air bubbles that heavily reduces the transducer / echosounder performance. A transducer mounted in the vicinity of the ship's stern can be operated only while drifting, at the pier or at very low speed. The reason is that the stern area is generally disturbed by turbulence and air bubbles, dependent on ship's speed. Additionally vibrations and engine noise may be a source of disturbances. The sound signal cannot penetrate this layer, the bottom echo fades away and the digital display shows the zero echo ( 1 - 1.5 m) or "?". For this reason only the front transducer must be used while sailing. Page 5-1 L-3 ELAC Nautik Once the transducer has been installed, the system must be set up to take certain factors into consideration. These are: • Never paint the radiating surface of the transducer. • Transducer installation depth beneath the surface. • Transducer installation height relative to the lowest part of the ship's keel. • Blocking depth, a setting to prevent false digital depth readings caused by resonance of non-ELAC transducers. This setting need not be altered from ZERO if using ELAC transducers. • Frequency of the transducer. • Installation position of the transducer, e.g. BOW, AFT, Pt., Stb, (if 2 transducers are installed). When a transducer is installed, i.e. before the ship is launched, measure the height difference between the radiating surface of the transducer and the lowest part of the keel and the distance between the waterline and the radiating surface of the transducer. These measurements are needed to compensate the differences when the system is initially set up. The transducer frequency can be found in the shipping documents. Connect the system up in accordance with the connection diagram which can be found in chap. 6. When cabling the system, take especial care that all signal lines are screened properly. The cable from the transducer to the connection box must be laid in an iron tube. From the connection box to the echo sounder there are three choices for a proper cable laying: - the transducer cable is laid within an iron tube - a double-screened cable is used as transducer cable, the inner screen is one-side connected to the echosounder's ground, the outer screen is one-side connected to the ship's ground.( see Figure 5- 1) - the transducer cable is laid apart at least 500 mm from all other cables. By no means a single screened cable must be laid together with any other cable. Page 5-2 L-3 ELAC Nautik 5.1.1 DISTORTION LEVEL TEST After routing and connecting the transducer cable a distortion level test has to be carried out, to ensure the correct routing and screening of the transducer cables. Test procedure: 1. Switch on the echosounder LAZ 5100 2. Select 500 m range 3. Select Display Gain 10 (max.) 4. Select Display Mode 1/2 for Dual Channel Unit 5. Select Item Gain, man. in the Parameter Menu 6. Select Gain 15 (max.) 7. Check the recording on the LCD – Screen. Below the transmitting pulse and echo signals no or only light distortion shall appear on the screen. 8. If strong distortion appear, check and correct transducer cable routing and screening according to the Installation Instruction. 9. Repeat test procedure until the display is free of distortion. 10. Return to normal mode Connect up peripheral equipment, i.e. external PC, printer, remote display unit etc. in accordance with the above mentioned connection diagram and referring to Figure 3-3 in chapter 3.5.

The transducer(s) should be cleaned whenever an opportunity arises, e.g. when the ship is in dock. The Transducer(s) can be cleaned using a plastic scraper or scrubbing brush, see note below. NOTE: Never use metal scrapers or wire brushes to clean the transducer(s). Never paint the radiating surface of the transducer(s). Page 5-13 L-3 ELAC Nautik The housing of the control and display unit can be cleaned using a non-abrasive household cleaning agent. Use window/glass cleaning fluid to clean the display area screen. Do not apply unnecessary pressure to the screen area when cleaning. If the system cables are exposed, i.e. are not run in ducts or tubes, check them at monthly intervals for insulation damage. If the system is defective and requires repair, onboard service is normally not possible because of the high density electronics. Onboard service is done by exchanging PCB´s ( Printed Circuit Boards), a list of spare parts available can be seen overleaf.
