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

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)

7

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:

This section can be enabled or disabled using the GPS Display

on/off button at the top of the Home screens.

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).

of system printers in the Hardware Interface

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

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 The Installation Pipe [6]


o Installation Pipe Rubber Gland [5]


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.


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.


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.

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.
