GENERAL INSTALLATION INSTRUCTION FOR ECHO SOUNDERS
TH 52 603 8001 EN Rev.: S Technical Manual LAZ 5100 / ES 5100 2-1
2 GENERAL INSTALLATION INSTRUCTION FOR ECHO SOUNDERS
2.1 General Remark to Hydro Acoustic Equipment
Even with a carefully selected transducer position and proper installation, the function
of hydro acoustic equipment can be impaired by turbulence, acoustic noise or aerated
water.
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.
Loosing 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.
2.2 Transducer Installation
The performance of an echo sounder is limited by the acoustic propagation of sound
in water. This is mainly influenced by the transducer mounting place, the
operational frequency and the transducer efficiency.
The transducer mounting place must be selected 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 be returned.
Therefore 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 disturb echo sounding
operation.
While the bow thruster is operating, no echo sounding is possible because of the
propeller rotation. On ships with bulbous bow 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 effective during low speed travelling.
An indication for this 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.

GENERAL INSTALLATION INSTRUCTION FOR ECHO SOUNDERS
2-2 Technical Manual LAZ 5100 / ES 5100 TH 52 603 8001 EN Rev.: S
2.2.1 Cable Length, Operating Frequency
Both the operating frequency and the length of cable between the echo sounder and
the transducer influence the performance of echo sounding.
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.
For information about ELAC-transducers (e.g. maximum measurable water
depth, cable length, operating frequency) see section 5.1.3.

TH 52 603 8001 EN Rev.: S Technical Manual LAZ 5100 / ES 5100 2-3
2.2.2 Cabling, Cable Location, Cable Specification
When installing the connection cable, observe the following:
Do not exceed permissible bending radius of the cables (see corresponding
dimensional drawings)!
Do not lay cable over sharp corners and edges.
Do not use metal cable ties for fixing the cable.
A strain relief of the cables must be installed by the shipyard.
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 echo
sounder.
In all connection boxes the screens are sliding and not connected to ground.
Dismantling has to be as short as possible.
The transducer cable from the transducer to the first connection box has to be fed
through a steel protection pipe.
From the first connection box to the echo sounder, the following kinds of cable laying
are mandatorily recommended:
the cable is laid in a steel pipe, that is connected to the ship’s ground.
Placing the cable duct inside a steel pipe allows to replace the transducer
without docking the ship and is required by many classification associations.
a double-screened cable is used as transducer cable, the inner screen is one-side
connected to the echo sounder's ground, the outer screen is connected to the
ship's ground on both sides.
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.
Shielded cable has to be used over the whole distance from the transducer to
the echo sounder. All connection boxes must be metallic.

2-4 Technical Manual LAZ 5100 / ES 5100 TH 52 603 8001 EN Rev.: S
2.2.3 Transducer Cable Specification
The cable from the transducer connection box to the echo sounder must be approved
marine cable (double screened).
At least a resistance <13 Ω/km and a capacity of < 150 nF/km is required.
2.2.4 Interfaces
The Echo Sounder has the following interfaces:
Printer interface: Standard CENTRONICS parallel interface, cable length: 5 m
maximum.
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 NMEA-equipment with RS 422 interfaces can be connected to the echo
sounder, otherwise the interface electronic will be damaged.

3.2.2 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 consists 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 version, working with different transducers on
different frequencies, see chapter 3.4 “Technical Data”.
The display area shows the following:
One channel (used with only one transducer)
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
Two channels (used with two transducers)
vertical split display shows on the left half channel 2 information, on the 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).
3.2.3 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 metal.
3.2.4 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 enhance the system capabilities:
Digital Slave Display(s) (see 3.3.1)
Printer (see 3.3.2)
Connection Box (see 3.3.3)
Transducer(s) (see 3.3.4)
Switch Box (see 3.3.5)
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.
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.
CAUTION!
While crossing steep slopes the echo evaluation might fail.
A steady depth display cannot be guaranteed in this case.
The 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 or to print out a hard copy of events from any time within the previous 24 hour
operating period.
3.3.3 Optional Connection Box
The optional Connection Box (see Figure 3-2) is connected to the Display and Control
Unit and provides the following connections:
a second Digital Slave Display
a blanking pulse output
depth alarm relay contacts (potential free)

3.3.4 Transducer Options
If the installed version is a dual channel version, 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 dual channel version is installed, a switch box (not part of delivery) can be used
for the connection of two transducers of the same type (frequency).

4.3 Display Area
4.3.1 Single Channel Display
The Display Area is used to present 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).

NAV OFF
Flashes to indicate that the Navigation mode is not in use i.e. the user have
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 4.5.1.1, NAV-Defaults). If the echo sounder is in the dual
channel mode (only if the second channel and a second transducer is fitted),
NAV - OFF is activated without flashing.
LONGITUDE/
LATITUDE
These windows will display the actual Lat. and Lon. (only if the system is
connected 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 occurs, the relevant window will flash.
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.

Figure 4-4: Single Channel Display
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:
Meters (m; as shown)
Feet (ft)
Fathoms (ftm)
WARNING!
If no valid bottom depth is available, instead of the depth value a “?” appears.
The reason can be loss of the bottom signal by distortion or other influence
or the bottom depth is out of the selected range.
Therefore in case of the “?” appearance check the selected range and the
analogue bottom trace.
While crossing steep slopes, the echo evaluation might fail. A steady depth
display cannot be guaranteed in this case. The 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.

In the two channel mode, information about location and frequency of the transducer
in use is added.
Figure 4-5: Two Channel Display
If the presentation channel 1/2 is selected, Information of both channels is shown in a
vertical split display.
The indication NAV OFF is activated without flashing to indicate, that the
mode of presentation is non standard. For each transducer the depth location
and frequency is shown.
For transducer location and frequency see chapter 5.1.4 Initial System SetUp.
4.3.2.1 Warning Fields
Three warning fields are shown on the display:
Field Explanation
NAV OFF
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 without flashing appears in the 2 channel mode. It indicates
that in this display mode the user has to observe, that for instance
digital slave repeaters are in use.
POWER ERROR
POWER ERROR occurs when the supply voltage of the echo sounder
unit falls below 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.

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).
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.
4.4.1 GAIN, RANGE and DIM Settings
GAIN (amplification), RANGE (depth range) and DIM (display area background
lighting 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.
4.4.1.1 GAIN Settings
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 . To decrease the GAIN level,
press the GAIN key .
The set value will appear on the display area above the key (between 1 and 10).
Pressing the same key a second time will increase or decrease the value 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 4.5.2.5.

TH 52 603 8001 EN Rev.: S Technical Manual LAZ 5100 / ES 5100 4-7
4.4.1.2 RANGE Settings
The RANGE can be set to suit the circumstances e.g. if a water depth of 35 m is
indicated, the 50 m 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 will decrease the range and pressing the RANGE key 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

4.5.1.1 NAV-Defaults
NAV (Navigation)-Defaults are basic compulsory settings which must be used when
operating the system for navigational purposes. These are defined by the International
Maritime Organisation (IMO) and state that:
The system must operate with one channel only
The sound velocity must be set to 1500 m/s
The unit of measurement must be metric ( meters)
Water depth must be measured below the keel (DBK)
If the system is being operated in any other mode, e.g. units selected are feet or
fathoms, water depth from the surface is selected etc., the user can return to the NAV
mode by calling up this MENU and selecting NAV-Defaults. A sub menu will appear
in which the user can choose between selecting NAV-Defaults and returning to the
ALARM MENU. The sub menu is shown overleaf.
This function will
set the sounder
to NAV-Defaults !
Continue ? NO (NO, YES)

4.5.1.2 Maximum and Minimum Depth Alarms
The user can set the system alarm so that an audio/visual alarm is released if the
water becomes more shallow than a set minimum or deeper than a set maximum.
This depth is always measured from the ship's keel. An Alarm Test facility is available
so that the alarm function can be periodically tested. These settings are done as
described in chapter 4.4.3.
The audio alarm can be muted externally by a connected Mute Control.

5 INSTALLATION, CARE AND MAINTENANCE
WARNING!
Danger for man and machine
The operational safety of the system will be endangered if work is not carried
out correctly and/or if unauthorised modifications are made!
Repair work must be carried out by suitably qualified, trained and authorised
specialist personnel (see chapter 1.2.2)!
The applicable local safety regulations must be strictly adhered to when
carrying out maintenance or repair work on the system!
5.1 Installation
The display and control unit can be panel-, bulkhead-, deck head- 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 52 603 8001 which is enclosed in chapter 6
"DRAWINGS" of this manual.
At the mounting place, no direct sun light should influence the visibility of
the display. For clear display readings a viewing angle of ±50° perpendicular
to the display is recommended.
The echo sounder 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
reflected by any layers of air bubbles or turbulence are so strong, that the sound
cannot pass the layers and thus echo sounding is prevented.
Because of this, 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 echo sounder will
be degraded by turbulence and air bubbles. Even a total echosounding break
down is possible.
During bow thruster operation, echo sounding is not possible because a wide area
around the thruster´s outlet is saturated with turbulence and air bubbles.

5-2 Technical Manual LAZ 5100 / ES 5100 TH 52 603 8001 EN Rev.: S
On ships equipped with a bulb bow, the transducer must be mounted as far as
possible ahead, because the bulb generates a layer of air bubbles that heavily
reduces the transducer / echo sounder 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. In addition,
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 "?". Therefore only the front transducer must be used
while sailing.
Once the transducer has been installed, the system must be set up to under
consideration of several factors:
These are:
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 needs not to be altered from
ZERO if using ELAC transducers.
Frequency of the transducer.
Installation position of the transducer, e.g. BOW, AFT, Pt., Stb, (if two 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 necessary to compensate the differences when
the system is initially set up. The transducer frequency is shown in the shipping
documents.
Connect the system in accordance with the connection diagram (see chapter 6).
When cabling the system, take special care that all signal lines are screened properly.
The cable from the transducer to the connection box must be laid in a steel pipe.
From the connection box to the echo sounder there are the following choices for a
proper cable laying:
the transducer cable is laid within a steel pipe, that is connected to the ship’s
ground.
a double-screened cable is used as transducer cable, the inner screen is one-side
connected to the echo sounder's ground, the outer screen is connected to the
ship's ground on both sides ( see Figure 5-1).
The transducer cable is laid at least 0,5 m apart from all other cables.
By no means a single-screened cable must be laid together with any other cable.

5.1.2 Distortion Level Test
After routing and connecting the transducer cable, a distortion level test must be
carried out, to ensure the correct routing and screening of the transducer cables.
Test procedure:
1. Switch on the echo sounder
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 a light distortion shall appear on the screen.
8. If a strong distortion appears, 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 peripheral equipment, i.e. external PC, printer, remote display unit etc. in
accordance with the above mentioned connection diagram, referring to Figure 3-2
“System Block Diagram (with Options)” in chapter 3.2.1.

Tab. 9: Transducer type
The typical maximum water-depths are valid for transducer installation with
direct transmitting into the water.
For cable lengths longer than the ones mentioned in the table, the electrical
power of the echo sounder has to be increased according to manufacturer's
release.
If acoustic windows are installed, the performance can decrease drastically, due to the
losses in the passage of the acoustic beam through the fluid between transducer
surface and acoustic window and the acoustic window itself.
The losses are minimal, if the distance between transducer surface and acoustic
window is lambda/2 and the acoustic window is parallel to the transducer surface.
For frequencies higher than 50 kHz, acoustic windows generate high losses of
performance and should be avoided.

The CHANNEL 1 MENU allows the service technician to set the following parameters:
Draft: the transducer installation depth is entered here, i.e. the depth
of the transducer below the waterline, e.g. 5.6 m. This compensation allows
accurate surface to sea bed measurements.
Trim: the distance between the transducer and the lowest part of the keel is
entered here, e.g. 0.3 m. This compensation allows accurate keel to sea bed
measurements.
Blocking depth: this setting prevents false digital depth readings caused by the
effects of resonance of non-ELAC transducers. If the water depth is less than the
depth set here, the digital display will show a „?“ but the analogue depth reading
will be displayed correctly.

5.2 Care and Maintenance
The Navigation Echo Sounder is largely maintenance free.
The transducer(s) should be cleaned whenever an opportunity arises, e.g. when the
ship is in dock. The transducer(s) can be cleaned with a plastic scraper or scrubbing
brush, see note below.
Never use metal scrapers or wire brushes to clean the transducer(s). Never
paint the radiating surface of the transducer(s).
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 when cleaning.
If the systems 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.
For support and ordering of spares contact the address below stating part(s) required
and identification number(s).
