2 Introduction to EMES60
2.1 Summary
EMES60 is a combined electromagnetic speed log and
echosounder navigation system. It is a single sensor with two
transducers in one housing.
Both parts have been designed to meet the relevant international
standards and provide all the modern and legacy input-output
interfaces that are specified by the IMO standards.
As required by the relevant regulations, the two parts are totally
separated internally.
The main advantage of this arrangement is that the system only
needs one hull penetration, and one set of mounting hardware,
thus increasing reliability and reducing costs of installation and
maintenance.
The size and weight of the sensor is significantly less than other
systems on the market, which greatly facilitates installation and
handling.
2.2 Highlights
Only one hull penetration, which increases safety of
navigation
Small overall diameter of sensor, requiring small hull
penetration, which minimizes the risk of mechanical
damage
Sophisticated analog and digital signal processing, which
provides reliable data in any navigation conditions
All modern and legacy input-output interfaces are
supported, including IEC61162-1/1 and IEC61162-450 (Light
Weight Ethernet)
Sound speed calibration based on temperature, which
provides accurate depth measurements in different
conditions without the need for manual adjustments
Includes water temperature sensor, accurate to 1°C
Optimized electromagnetic log operational parameters,
which provides accurate speed through water
measurements in different water conditions, such as sea
water, river water, and brackish water
6
3 Operation
3.1 HMI Touch-Screen Controls
Reading the speed and depth information from the system, and
configuring the system for use, is done through the touch-screen
display units, called “human-machine interface” (HMI) units.
Data is also sent to external equipment using a range of standard
communication protocols and data formats.
Two HMI Units are usually fitted, both of which can run both the
echosounder and speed log parts of the system, but typically one
is configured to run the echosounder, and the other is configured
to run the speed log.
The HMI Units use touch-screen technology, so that controlling the
system is done by touching the relevant part of the HMI Unit
screen.
The structure and operation of both HMI units is similar. The
examples below are from the speed log, but the principles are the
same for the echosounder.
3.1.1 Structure of the screen
Summary data: (3.1.2)
Control buttons, time: (3.1.4)
Main window: different for each screen
type
Window navigation: touch a circle to
move to a new screen (3.1.9)
Settings buttons: touch to change
settings, and Home access (0)

The exact contents of the parts of the screen are different for
each screen type; see the section for each screen for detailed
information.
3.1.2 Summary data
All the screens show a summary of the data measured by the
system in the top row of the screen, together with GPS position.
The speed log HMI shows:

Options for the speed log are:
“mph”: miles per hour
“kn”: knots
“mph” is statute miles per hour (the measure of speed commonly
used for land speeds in some countries). “Knots” are nautical miles
per hour.
Most of the other displayed values have similar controls that are
accessed by touching their display box.
3.1.4 Control buttons
The second row has a set of buttons, which provide numerical
outputs as well as controls for the system. Each screen type is
slightly different, but a typical one is as follows.
3.1.5 Printing and screen snapshots
Touch the Print Screen button to send data
from the screen to a printer.
In Echosounder mode, this will start a
continuous printout of the echogram and the
GPS position data.
In Speed log mode, it makes a copy of the
screen for debug and maintenance purposes.
The function of this button is controlled by the
selection of the Screen copy selection in the
Hardware Interface Selection screen (section
3.1.14).

Selection screen.
3.1.6 Setting the time
Touch the time display box to open the
time-setting menu. Click on the hours,
minutes or seconds, and use the up and
down arrows to change them. Then touch
the “tick box” to set the new time.
3.1.7 Alarms
If a value goes over a minimum or maximum limit, an alarm can
be triggered. This causes the
following things to happen:
A flashing display is shown in
a prominent position on the
screen
Up to two alarm states are shown in the bottom row of the
screen
The alarm state is logged to an alarm list, with the time of
the alarm
One of the relays in the Interface Unit is switched. These can
be used to trigger audible alarms or set an alarm in other
systems.
To accept an alarm, causing the on-screen warning to disappear,
touch the flashing warning box. More than one alarm condition
could be in place at the same time, so it may be necessary to
repeat this procedure to accept the other alarms.
Some values displayed are colored according to the alarm
condition, even if the alarm has been accepted. For example, the
numerical display of depth will be:
Red in the “too shallow” alarm state
Amber in the “too deep” alarm state
The alarm states are controlled and monitored using the Alarm
screens, see section 3.1.7.
3.1.8 Setting alarm limits
The values at which alarms sound are shown in Alarm Buttons at
the bottom of the screen. There are typically two buttons, one for
the alarm when the value gets too low, and one for when it gets
too high.
10
To change these values, touch
one of the alarm buttons.
A pair of slider bars appears on
the screen; move the low
(“Lo”) and high (“Hi”) sliders to
change the alarm levels.
The alarm values in the alarm
buttons change to show the
new selections.
3.1.9 Window navigation
Use the Window
Navigation part of
the screen to go
directly to a different screen: touch the dot for the required
screen. Alternatively, “swipe” to left or right to move to an
adjacent screen. The current screen is shown as a filled dot.

demo and simulation modes are set in
the Home screens; touch the mode
button and select the required mode.
Warning: ensure that the mode is set to
Normal when EMES60 is used for
navigation.
The available modes are:
Normal: the information shown in the screens and the
outputs from the external interfaces are driven by the
measurements made by the speed log and echo sounder
sensors.
Demo: the screens are driven by artificial speed log and
echo sounder data, which is computed inside the EMES60
software. This is useful for training, when real data from the
sensor head is not available.
Simul: simulation mode; in this mode, the screens and
outputs are also driven by data computed by the EMES60
software, but the operator can program the parameters of
the data that is shown and output.
To set the simulation parameters: select simulation mode, then go
back to screen 1. Click in the area of the digital depth (or speed)
indicator.

4 Maintenance
EMES60 is very simple and robust, and needs very little regular
maintenance. However, the following instructions should help to
keep an EMES60 system accurate and operational.
4.1 Precautions
4.1.1 Operation in Air
The transducer may be damaged by prolonged operation in air.
After the initial dockyard installation tests, and before dry-docking,
make sure that the system is disconnected from the electrical
power supply.
4.1.2 Sensor Head
Do not open the sensor head. There are no user-serviceable parts
inside.
4.2 Tests and Checks
Run the following tests and checks after Installation and at regular
test intervals.
4.2.1 Safety check
Inspect all components of the system for safety, including:
Ensure that all electrical supplies are intact and
undamaged
Ensure that all cables are properly fixed down
Check for water leaks around the valve assembly
4.2.2 Connector checks
Check the state of all cables and connectors. Loose or damaged
cables and connectors are probably the most common source of
system problems.
4.2.3 Electronic Unit Checks
Check the state of the electronic unites.
Ensure that the electronic unites are firmly fixed in place
Check that the cable glands are still holding the cables
firmly and that their rubber seals are intact, undamaged
and not starting to “perish”
Check for corrosion inside and out
Check that all the pluggable terminal blocks are still firmly in
place
Check that all of the terminal block screws that hold the
wires in place are still done up tightly
44
Check and replace if necessary the silica gel packs inside
the electronic unites
4.2.4 Inspect transducer for marine growth
Marine growth on the surface of the transducer will reduce its
efficiency and degrade the accuracy. All such marine growth
should be removed as gently as possible: do not use sharp tools or
mechanical grinders; otherwise, the transducer face can be
damaged.
Pay particular attention to the electromagnetic speed log
electrodes, which are small steel fixings in the face of the
transducer head; they must be clean and untarnished. Carefully
remove any tarnishing, corrosion, or marine growth from these
electrodes using fine abrasive sheet or wire wool, making sure not
to damage the surrounding plastic of the sonar transducer.
4.2.5 Corrosion check
Check all items for corrosion.
4.2.6 Cleaning
Clean the HMI screens and electronics systems:
Electronic unites: use a damp cloth, no solvents.
Display screens: use a soft cloth lightly moistened with a mild
detergent solution, then wipe clean with a soft dry cloth. Do
not use tissue paper, which could scratch the screens.
Sonar assembly: wipe over with a soft cloth lightly moistened
with a mild detergent solution.
4.2.7 Functional checks
The following tests check the function and correct connection of
the EMES60 system.
The LEDs and test points are described in section 6.2.

4.2.8 Routine Tests
The following tests and observations help you to be confident that
the system is working correctly:
HMI Screens
o Put the system into Demo mode (an option in the
Home screens, section 0), and check that the screens
update regularly with the Demo data. Remember to
disable Demo mode after this test.
NMEA data input
o Input NMEA data is echoed to the communications
screens (3.2.12 and 3.3.5); use this screen to check
that the data is being correctly received.
Echosounder
o Compare the echosounder depth with the depth that
you expect from the chart, accounting for tide
o Look at the Echosounder oscilloscope screen (section
3.2.18) to check that the history of echosounder
values looks reasonable for the seabed type, and the
echo strengths are neither too weak nor too strong.
o Inspect the results of the self-test processes provided
in the Echosounder test and troubleshooting screen,
(3.2.19)
Speed log
46
o Compare the speed log speed with the GPS speed,
which is shown in the top-left corner of most HMI
screens. Any difference in the two speeds should be
related to water currents.
o Check that the history of speeds in the speed log
history screen (3.3.8) matches what you know of the
recent movements of the vessel
o Inspect the results of the self-test processes provided
in the speed log test and troubleshooting screen
(3.3.10).

5.2 Mounting the Sensor on the Vessel
The sensor must be mounted in a water-tight valve or tank, so that
the face of the sensor is flush with the surface of the hull. This is
important in order to minimize turbulence around the sensor face.
The sensor should be mounted:
Where there is space on the inside of the hull to access the
unit for installation and maintenance of the sensor
On a section of the hull that is flat and horizontal, and large
enough to ensure laminar flow over the sensor face
With the transducer face as horizontal as possible: within ±1°
As close to the vessel’s centerline as possible
As far forward on the vessel as possible, ideally just behind
the bulbous bow, and always in the front half of the vessel
As deep as possible, where it remains underwater at all
speeds, conditions and vessel loadings
Away from sources of turbulence or entrained air bubbles in
all weathers, speeds and vessel loadings. Avoid:
o Bow thrusters
o Objects that protrude from the hull
Where risk of damage, for example from anchor chains, is
minimized
It may be necessary to modify the hull to provide a horizontal
mounting surface. If this is done, make sure that any welds are
smoothed off to minimize turbulence.
Make sure that the direction markings on the sensor match the
forward direction of the vessel.
Before any welding:
Remove O-rings and any parts that may be damaged by
heat
After welding:
Grind down to ensure a flush finish
Paint the fitting and hull with anti-corrosion and anti-fouling paint,
but do not paint the active surface of the sensor.
53
5.3 Sensor Deployed and Inboard
When the vessel is afloat, the sensor is deployed below the hull on
the end of the installation pipe. But before the vessel is launched
or dry-docked, the sensor must be brought inboard so that it is not
damaged.
The two states are shown in the images below.
Figure 1 Sensor Deployed (Ball
Valve and Bottom Flange
omitted for clarity)
Figure 2 Sensor Inboard
54
5.3.1 Installing the sensor in the valve
EMES60 is usually mounted in the Sensor Head Assembly, (shown in
5.1.3 above), which is then fitted into the Ball Valve Assembly
(5.1.4).
5.3.2 Cautions
Take care not to damage the inner surfaces of the valve; do
not attempt to lift the valve by passing rope, strops or chain
through the valve.
Do not paint the surface of the sensor.
Any modifications made to the vessel to fit the valve may
require approval of the appropriate classification body.
5.3.3 Fitting the Bottom Flange to the hull
The Bottom Flange is welded to the hull, and the rest of the
assembly is fixed to the Bottom Flange. See section 6.4.1 for a
drawing of the Bottom Flange.
To fit the Bottom Flange to the hull:
Disassemble the Bottom Flange from the valve assembly
Cut a 187mm diameter hole in the hull
Weld the flange to the hull
Grind down the weld to ensure a flush finish
Paint the flange and hull with anti-corrosion and anti-fouling
paint
Check that the inner and top surfaces of the Bottom Flange
are free from dirt, swarf, paint, etc.
Caution: when welding the bottom flange to the hull:
Protect the machined bottom and inner surfaces from
damage and debris. Damaged or dirty surfaces may not
give a good water seal.
55
Do not allow the flange to over-heat; allow cooling time,
particularly when welding to thick hull plates or stainless
steel parts.
Ensure that the welder is suitably qualified and certified.
5.3.4 Assembling the Sensor Head Assembly
The Sensor Head Assembly is deployed inside the Ball Valve
Assembly. The Sensor Head Assembly must be assembled first.
An exploded view of the Sensor Head Assembly is shown in 5.1.3
above, and it is shown in cross-section below.
The Sensor Cable is supplied fixed to the top of the Sensor
Housing. Take care not to damage the seal and connection
56
of the cable to the housing; do not lift the housing by the
cable.
Pass the following components over the length of the Sensor
Cable, in the following order, referring to the diagram
above to check which way round the parts are fitted:
o Adapter Rubber Gasket [2]
o Adapter, 60mm [3]
o Installation Pipe Washer [4]
o Installation Pipe Rubber Gland [5]
o Installation Pipe Washer [4]
o The Installation Pipe [6]
o Installation Pipe Washer [4]
o Installation Pipe Rubber Gland [5]
o Installation Pipe Washer [4]
o Installation Pipe Nut [7]
Place the Adapter Rubber Gasket on top of the Sensor
Housing.
Place the Sensor Head Adaptor (60mm) on top of the
Adaptor Rubber Gasket, and fix it to the Sensor Housing
using 4 M5X15mm socket head screws.
Grease the Installation Pipe Washers with silicone grease
type 6014 or equivalent.
Fit the first Installation Pipe Washer on top of the Sensor
Head Adaptor, then the Installation Pipe Rubber Gland, and
finally another Installation Pipe Washer.
Offer the Sensor Head Adaptor, with Sensor Housing fitted to
it, to the end of the Installation Pipe. Carefully turn the pipe
so that the Sensor Head Adaptor screws into the end of the
Pipe. Note that the top Installation Pipe Washer is pushed
against the step inside the pipe, so that the Adaptor Rubber
Gasket is compressed when the pipe is screwed down onto
the Adaptor, thus causing it to bulge outwards and form a
seal against the pipe. This requires 40-50Nm torque.
When the Installation Pipe is fully screwed home over the
Adaptor, lock it in place with an M4x8 mm Set Screw [8],
using 1.5Nm torque, fixed with Loctite 222.
Grease the remaining two Installation Pipe Washers with
silicone grease type 6014 or equivalent.
At the top of the Installation Pipe, fit the Installation Pipe
Washer, Installation Pipe Rubber Gland and the last
Installation Pipe Washer into the end of the Installation Pipe.
Carefully insert the Installation Pipe Nut into the top of the
Installation Pipe, and rotate it so that it screws into the Pipe
and seals the cable at the top of the pipe.
The Sensor Head Assembly is now ready to be fitted into the Ball
Valve Assembly.
57
5.3.5 Assembling the Ball Valve Assembly
Refer to the images in section 5.3 above to see how the Sensor
Head Assembly is fitted into the Ball Valve Assembly. The parts of
the Ball Valve Assembly are shown below.
Pass the Sensor Cable and Installation Pipe through the Top
Flange (60 mm) [9].
Run the following parts over the length of the Sensor Cable,
and then over the length of the Installation Pipe, in order:
o 2 Top Flange Rubber Glands [10]
o The Top Flange Washer [11]
o The Top Nut [12]
Pull the Installation Pipe back through the Top Flange, so
that the Top Flange Rubber Glands and Top Flange Washer
58
fit inside the top of the Top Flange, and carefully and loosely
screw the Top Nut into the Top Flange. Do not tighten the
Top Nut yet.
Rotate the Installation Pipe so that the Sensor Head will face
forwards when the Top Flange is fitted to the rest of the
assembly. Refer to the alignment marks on the Sensor Head;
see the diagram below.
Push the Sensor Head Assembly fully up through the Top
Flange, so that the Sensor Head is completely inside the Top
Flange.
Tighten the Top Nut to compress the Top Flange Rubber
Glands, and lock it in place using two M8 screws [13]; one
locking the Top Nut into the Top Flange, and the other
locking the Installation Pipe into the Top Nut. Note that
tightening the Top Nut compresses the Top Flange Rubber
Glands, which creates the water seal between the
Installation Pipe and the Top Flange.
5.3.6 Fitting the Assembly to the Bottom Flange
The complete assembly is fitted to the hull using the Bottom
Flange, which has been welded to the hull: see 5.3.3 above.
Screw four Pin Screws [2] into the Bottom Flange [1].
Place the Bottom Flange Gasket [3] on top of the Bottom
Flange.
Place the Ball Valve [7] over the Pin Screws, and fix it in
place using four M16 washers [6], four M16 Spring Washers
[5] and four M16 nuts [4]. Place the Ball Valve so that its
handle is in a convenient orientation for use when installed.
Tighten the nuts on the threaded rods to 90Nm.
59
Screw four Pin Screws [2] into the top of the Ball Valve.
Place the Gasket [3] on top of the Ball Valve
Check that the Sensor Head will face forwards when the
Top Flange is fitted to the Ball Valve; if necessary, loosen the
Top Nut and locking screws to allow the Installation Pipe to
be rotated.
Place the Top Flange, with the Sensor Head Assembly inside
it, over the Pin Screws on the top of the Ball Valve, and fix it
in place using four M16 washers [6], four M16 Spring
Washers [5] and four M16 nuts [4]. Take care not to
damage the sensor’s active surface when lowering the
assembly onto the Ball Valve.
Tighten the nuts on the threaded rods to 95Nm.
Loosen the Top Nut and locking screws to free the Sensor
Head Assembly, but take care that the Sensor Head
assembly does not fall.
Carefully lower the Sensor Head using the Installation Pipe
until it stops. Check that it is flush with the hull, and facing
forwards.
Lift the Installation Pipe again until it stops, so that the Sensor
Head is inside the Top Flange.
Tighten the Top Nut and locking screws to hold the Sensor
Head Assembly in place.
Turn the handle on the Ball Valve to close it. This will protect
the Sensor Head when the vessel is launched.
5.3.7 Checks after assembly
Visually check the assembly for water-tightness.
Check that there are no particles of dirt, metal swarf, etc.,
inside the assembly. These could affect water-tightness.
5.3.8 When the vessel is afloat
Prepare the system for operation when the vessel is afloat after
dry-docking as follows.
Turn the handle on the Ball Valve to open it.
Loosen the Top Nut and locking screws to free the Sensor
Head Assembly. This will also allow any air inside the
assembly to be expelled; look out for water leaking
between the Installation Pipe and Top Nut when the air has
all been driven out; re-tighten the Top Nut a little if
necessary.
Carefully lower the Sensor Head using the Installation Pipe
until it stops. Take care not to rotate the Installation Pipe, so
that the Sensor Head continues to face forwards.
60
Tighten the Top Nut (to 75Nm) and locking screws to hold
the Sensor Head Assembly in place. Use 1.5Nm torque, and
fix with Loctite 222.
5.3.9 Removing the sensor while the vessel is afloat
The sensor can be removed from the valve while the vessel is
afloat, as follows.
Caution: loosen nuts gradually, as water pressure may exert large
forces on the sensor assembly. Proceed carefully and look out for
water leaks.
Loosen the Top Nut and locking screws to free the Sensor
Head Assembly.
Lift the Installation Pipe until it stops, so that the Sensor Head
is inside the Top Flange.
Re-tighten the Top Nut and locking screws.
Turn the handle on the Ball Valve to close it.
Remove the M16 nuts and washers that are holding the Top
Flange to Ball Valve.
Carefully lift the Top Flange, with the Sensor Head inside it,
from the top of the Ball Valve.
The Sensor Head can now be accessed by loosening the
Top Nut and locking screws and pushing on the Installation
Pipe.
5.3.10 Re-fitting the sensor while the vessel is afloat
Re-fitting the sensor is very similar to the initial installation (see 5.3.4
above).
Assemble the Sensor Head to the Installation Pipe and Top
Flange with the Sensor Head fully raised, as described
above.
Fit the Top Flange to the Ball Valve, and tighten the Top Nut
and locking screws.
Make sure that the assembly is re-fitted so that the Sensor
Head faces forwards; check the mark on the Sensor Head.
Use the valve handle to let water into the valve.
Carefully undo the Top Nut until water starts to seep out,
and then fully lower the Sensor Head.
Re-tighten the Top Nut (75Nm) and locking screws.
5.3.11 Preparing for dry dock
If the vessel needs to be dry-docked again, loosen the Top
Nut and locking screws, and lift the Sensor Head by 50mm
to protect its active surface.
61
5.3.12 Cathodic protection
Minimize corrosion of the sensor head by fitting a sacrificial anode.
Suitable anode types include SAF24 and SAF12 on steel hulls, and
AG4 or AG4 MC on aluminum hulls.
Regularly inspect the anode and replace it when necessary.
62
5.4 Mounting Electrical Components
The electrical components of the system are:
Sensor Power Unit
o This supplies power to the sensor head and
communicates with the Interface Unit.
o It should be mounted in the forepeak, close to the
sensor, where the cable lengths are no more than 30
meters from the sensor (40 meter cables are available
on request) and no more than 600 meters from the
Interface Unit.
Interface Unit
o This connects the system to the HMI Units and any
other external equipment that needs the speed log or
echosounder information.
o It should be mounted in the bridge area, where the
cable lengths are no more than 600 meters from the
Sensor Power Unit and no more than 100m meters
from the HMI Units and connected external
equipment.
HMI Units
o These provide graphical and numerical readouts of
the speed and depth information from the sensors,
and allow the user to set the control parameters of
the system.
o Two units are provided, both of which can control
and monitor both echosounder and speed log, thus
providing redundancy.
o The HMI units should be mounted in the bridge or
overhead console, where the cable lengths are no
more than 100 meters from the Interface Unit.
External equipment
o EMES60 can be connected to external equipment,
not supplied by Northern Solutions, using standard
data communications protocols and data formats.
o The maximum distance from the Interface Unit to the
external equipment is 500 meters.
5.4.1 Mounting the HMI units
The HMI units need to be mounted in a panel. Prepare a
rectangular hole 138.0 mm wide and 192.0 mm high. The exterior
dimensions of the unit are 149 x 202mm.
33mm depth is needed behind the panel, plus at least 20mm to
allow for air cooling and for the NMEA Adaptor Board.
Note that the HMI unit is used in “portrait” mode, with the long side
vertical.
63
NMEA communications is made through an NMEA Adaptor Board,
which converts RS422 signals at the 9-way D-type connector on
the HMI unit into NMEA 0183 signals on a screw terminal.
Figure 3 HMI unit dimensions
64
5.4.2 Mounting Electronic Units
Mount the electronic units with the glands facing downwards, to
minimize the risk of water ingress and ease cable routing.
66

5.5.3 Cable Diagram
The cables used in the system, with their names, are shown in the
diagram below.
67
The number of cables leading to external equipment depends on
the number of external systems that are required to be connected
to EMES60. In the diagram, IU-Ext1-* means IU-Ext1-1, IU-Ext1-2, IU-
Ext1-3, etc.
Regulations require that the speed log and echosounder sides of
the system must be independent of each other, so they have
separate power and communications connection cables.

Avoid running communications cables close to electrically noisy
systems and cables.
5.5.6 Pluggable Terminal Block connectors
All cable terminations are made using pluggable
terminal block connectors.
To terminate a cable, simply strip and twist the ends,
insert into the screw terminal, and tighten the screw.
These connectors are supplied with the EMES60 system.
5.5.7 Connection Notes
The following instructions must be followed when connecting up
the EMES60 electronic unites. Failure to do this may reduce the
integrity and robustness of navigation measurements.
69
The sides (echosounder and speed log) must be isolated
from each other: do not connect any signals, grounds or
power wires together.
NMEA outputs from sensor must only be connected to
correct opto-coupled NMEA inputs.
5.5.8 Connecting to Electronic Unites
The EMES60 electronic unites (Sensor Power Unit and Interface
Unit) are connected to each other, other parts of the EMES60
system, and external equipment using cables that are listed in
5.5.2. These cables are provided by the installer, except for the
sensor cable, which is provided as part of the EMES60 kit.
To connect a cable to an electronic unit:
Cut the cable to length
Cut back the jacket to expose the outer screen
Expose the outer screen for the gland connection
Keep twisted pairs together; don’t un-twist them
Strip the insulation on each core to 7mm
Refer to the wiring schedules in section 5.5.9 for each cable
Check where the cable terminates on the boards inside the
electronic unit, and select a gland in the side of the box
that minimises tail length inside the electronic unit. This
information is shown in the wiring tables below and on a
diagram fixed to the inside of the door of the electronic unit.
Loosen the gland
Feed the cable throughthe gland
Ensure the outer screen of the cable is electrically
terminated on the gland (this important for EMC screening
regulations)
Separate one pluggable terminal block from a circuit
board. Remove the blocks one at a time, to help make sure
that the headers go back in the right place on the board.
Match the numbers on the terminal blocks against block
and pin numbers in wiring tables
locations indicated in the pin numbering tables below.
Insert the pluggable terminal into header on board. Make
sure that the terminal goes back into the right part of the
header.
Ensure that cable core functions match the screen-print on
the board.
Seal any un-used glands.

5.5.10 Power
The EMES60 sensor is powered by the EMES60 Sensor Power Supply.
Each subsystem of the sensor consumes 230 or110VAC or 24VDC
(optional) at 6W maximum. Both can be connected at the same
time.
The AC power supply must be between 103.5V and 242V, 47.5Hz
to 63Hz.
DC power, nominally 24V, must be between 21.5V and 31V.
76
The HMI units require DC power, 24VDC at 12.8W maximum each.
The HMI units are powered from the Interface Unit.
The total consumption of each subsystem is 230/110VAC or 24VDC
at 16 W maximum.
5.5.11 Signal Connections
EMES60 supports the following signal output types:
Relay: maximum external connection 30V, 1A
Opto-coupler: maximum external connection 60V, 0.5A
4-20mA: output level 10V, load resistance must be less than
500Ω
0-10V: load resistance must be more than 500Ω
EMES60 supports the following signal input types:
Pulse inputs: 5 to 24V; high- or low-going pulses can be used
A 15V reference voltage is available in the EMES60 terminals for
use with the pulse inputs if required with voltage-free sources.
See section 3.1.3 for instructions on configuring the inputs and
outputs in the HMI interfaces.
5.6 Set-Up
The system is set up using the HMI Units. See section 3 for details of
the HMI screens.
5.6.1 Set Up the Hardware Interface
The Hardware Interface screens of the HMI (see 0) allow you to set
up:
The opto-isolated output channels
The pulse input channels
The analog output channels
The relay switches
The printer
5.7 Calibration
5.7.1 Calibrating the HMI touch-screen
The pointer on the HMI touch screen should appear exactly where
it is touched. If not, run the touch-screen calibration procedure.
77
The HMI unit offers two calibration processes, which are available
through the “PenMount Control Panel” application.
Standard Calibration Click this button and arrows appear, pointing
to red squares. Use your finger or stylus to touch the red squares in
sequence. After the fifth red point calibration is complete, to skip,
press ‘ESC’.
Advanced Calibration Advanced Calibration uses 4, 9, 16 or 25
points to effectively calibrate the touch panel linearity. Click this
button and touch the red squares in sequence with a stylus. To
skip, press ‘ESC’.
5.7.2 Water temperature calibration
Touch the temperature display box in the
speed log main operational screen
(section 3.3.2) to open the temperature
calibration control. This opens a control
slider. This function is used when calibrating
and commissioning the system, and allows the temperature shown
to be adjusted to match the temperature from another, trusted
temperature measurement. This feature is only used when
calibrating the system after installation or if the sensor
configuration parameters are lost. Do not touch this setting in
normal use.
To use this feature, read the current water temperature from, for
example, a thermometer lowered into the water, or the cooling
water inlet temperature sensor. Touch the slider bar, and move left
and right to set the value.
This feature can only be used in Administrator Mode (3.1.13).
5.7.3 Speed log Calibration
The electromagnetic speed log can be affected by magnetic
materials near to the sensor. It is therefore necessary to calibrate
the sensor after it has been installed. This is done by running the
vessel back and forth over the same line on the seabed several
times, and entering the data from these calibration “trips” into a
calibration table. EMES60 uses the data in the calibration table to
correct the speeds measured by the speed log.
See section 3.3.11 for instructions on using the speed log
calibration screen.
Speed log calibration is typically done during vessel sea trials.
A typical calibration sequence is as follows.
78
1. Choose a sea area to run the calibration trips. This needs to
be in open water, where the vessel can run between two
defined points, one nautical mile apart, at a range of
speeds up to 75% of the vessel’s maximum speed. The
effects of wind and tidal currents should be minimized.
2. On the Speed log HMI, open the Speed log Calibration
Screen. See section 3.3.11.
3. Select two points (which we will call point A and point B for
the purpose of this description). The points should be exactly
1 nautical mile apart (although other separations can be
selected if required: touch the distance indicator at the top
of the calibration screen to
enter a new trip distance).
Most users enter these points on the ship’s GPS plotter,
although it is perfectly possible to set up points using transits
by aligning landmarks from a paper chart, and measuring
the distance from the chart.
4. Line up the vessel on a straight course from point A
to point B, travelling at approximately 25% of the
ship’s maximum speed. When point A is reached,
press the trip start button
5. The progress along the first leg of the trip is shown as a
progress bar above the distance indicator. This progress is
derived by integrating the speed log speed, so it might not
be exactly correct yet.
6. When the GPS plotter (or selected external navigation tool)
indicates that point B, the end of the calibration trip,
has been reached, touch the trip stop button.
7. The trip start button will now be flashing, waiting for
the return leg of the trip. Turn the ship around, head back
down the same calibration line at the same speed. Press the
trip start button at point B, and the trip stop button when
point A is reached.
8. The software now gives the prompt message: “Set results in
calibration table?”
9. If you are confident that the results are good, select Ok,
then use the drop-down list to select a column number in
the Calibration table. The Calibration table is shown at the
bottom of the Calibration screen. You can either write to an
empty column, or over-write the data that is already in a
column.
10. Alternatively, you can postpone the entry of the calibration
trip data by pressing Cancel, and then check the trip data
before using it. This method is recommended at least for the
first time that the speed log calibration is done. Look at the
data from the latest trip, which will be shown highlighted in
79
the Calibration trips table. Look at the following values, and
check that they are within the limits of what you would
expect:
a. Trip time and Trip date, which should match the time
that the trip was run
b. Ref. Leg1 shows the speed of the first leg of the trip
(from A to B) calculated from the distance that was
entered in step 3 above and the time taken to run the
leg.
c. Log Leg1 shows the speed of the first leg of the trip as
measured by the speed log.
d. Ref. Leg2 and Log Leg2 show the same information for
the second leg of the calibration trip.
e. Ref. Aver and Log Aver show the reference and
speed log speeds, averaged between the two legs of
the trip
f. Dist Leg1, Dist Leg2, and Dist Aver show the distances
for the two legs, and the average, as computed from
the speed log speed.
g. Drift shows the angle between the forward and
sideways velocity, again for the two legs and the
average between them.
11. If these values all seem to be acceptable,
touch the column to select it, and touch the
Calibration Trip Use button.
12. You will be given the prompt message: “Set results in
calibration table?”, just as in step 8 above. As described in
step 9 above, you can put the values into a selected
column of the Calibration table.
13. Check that the values in the calibration table match what
you expect for the calibration trip:
a. Ref. shows the reference speed for the trip, computed
from time and distance
b. Log shows the speed from the trip as measured by the
speed log before calibration
c. Drift shows the angle between forward and sideways
speed components for the trip.
14. Repeat the process, from steps 4 to 13, A to B and back
again, this time at 50% of the ship’s maximum speed, and
again for 75% of the maximum speed. Enter all of the values
into the Calibration table. The table has five columns,
allowing you to run two more lines at different speeds if you
wish.
The Calibration table shows un-calibrated forward and sideways
speeds on the left of “Calibration table” and the calibrated results
80
on the right, so that you can see what the effect of the table is at
any time during the process.
If one of the calibration trips doesn’t work well, select it
by touching it, and press the Delete button to remove it
from the table.
If one of the columns in the Calibration table is bad, you can:
Over-write it from one of the columns in the Calibration trips
table (see step 9 above), or
Stop is being used in calibration calculations by selecting
any one (or all) of the values in the column by touching it,
and using the “backspace” key to delete the value.
Columns with any one of the three values blank are not
used; or
Touch a value in a table to edit it (see below to see how this
might be used).
When the calibration process is complete, if there is a printer fitted
to the system, use the Print button to make a print-
out of the calibration data as a record of the
process.
It is strongly recommended that the full calibration process is
followed as described above. However, alternative methods are
possible:
One-way trips: if it is certain that there is no effect on water
speed from wind or tide, you can use the results from one
direction only:
o At the end of the first run (A to B) touch the
end run button as usual, and then use the
Calibration Trip Use button to use the data
from the run so far.
o The Start button will now be flashing, waiting for you to
do the return (B to A) trip. You can clear this flashing
as follows: touch it, to start a “dummy” trip, then
touch the End button, and select “Cancel” from the
“Set results in calibration table?” prompt.
Use GPS speed data; this is ground speed, so only matches
the true water speed if there is no tidal current. But if this is
the case, then you could create a column in the Calibration
table as follows:
o Touch the Ref. field and use the keypad to enter the
GPS speed that is shown in the top-left of the window
o Touch the Log field and enter the raw value from the
speed log: this is shown to the left of the Calibration
table header.
81
o Enter zero (or a true value if known) into the Drift field.
Blanks in any of the fields cause the column to be
ignored in the calibration calculations.

6.5 Data Output and Input Formats
EMES60 outputs and inputs NMEA 0183 format messages to
communicate with external systems. These formats are defined in
standard IEC 61162-1.
6.5.1 NMEA 0183/IEC61162-1 Messages
These messages have a general format that is typified by the
following ASCII string. Each message is called a “sentence”.
$GPGLL,5057.970,N,00146.110,E,142451,A*27
All messages start with a ‘$’ character
Following the $ character are two letters giving a talker identifier
(GP in the example above). EMES60 provides the following talker
identifiers:
SD for the echosounder outputs
VM for the speed log outputs
Next are three characters called a “sentence formatter”, which
define the kind of sentence being used.
The text that follows is specific to each message type, and is
separated by commas ‘,’.
Finally there is a star ‘*’, and a two-character checksum, which is
calculated by exclusive- OR'ing the eight data bits of each
character in the sentence between, but excluding, "$" and "*".
The sentence is terminated with an ASCII carriage return and line
end pair, <CR><LF>, hexadecimal 0D and 0A.

7.1 The Company
Northern Solutions AS, based in Norway, is based on a group of
experienced and committed engineers and project managers.
The development team has over 20 years’ experience in
designing and supporting the products for the merchant fleet,
hydrographic market and fisheries. Products developed to date,
including single/dual channel and multi beam echosounders,
acoustic and electromagnetic speed logs, and different kinds of
operator and interfacing units, have an excellent reputation in the
worldwide navigation market.
The main scope of interest of the company is hydroacoustic and
electromagnetic instruments, including sensors, processing units
and man-machine interface for the marine equipment.
The company experience is built not only based on the design “in
front of the drawing board”, but also on many weeks on board
different kind of vessels, ranging from small size fishing boats up to
super tankers and container ships. This allows the designers to listen
to the opinion of a very important group of customers: the end-
users.
The company philosophy is very simple: to supply reliable products
and services at a competitive price, and to provide customers
with slightly more than they expected.
