___________________________________________________________________________

terminology

Terms, units and abbreviations used in this manual.

introduCtion

This part introduces you to the Compact speed log family.

Chapter 1 – physiCal installation

Correct installation of the system will ensure problem free service for many
years. This section explains the main steps to get your system working.

Chapter 2 – setting up the CompaCt display

The Compact display is a exible, yet intuitive display allowing data to be

displayed in a user friendly way. It is also a primary system and can be integrated
into the navigation system as required by the regulations. This chapter explains
how to set up the unit.

Chapter 3 – Calibration

Each new installation is unique and the system must be matched to the

vessel. Calibration is required to avoid inuence of mounting errors and that

hydrodynamics of the vessel are compensated for. This chapter explains the
procedure in a step by step guide.

Chapter 4 – runtime operation

Once the system is installed and operational, the user can change the screen to
show the data of interest at any particular time. This section explains the basic
operation of the system.

Chapter 5 – CheCking out your system

It is a good idea to verify your systems performance from time to time. This
chapter describes how to check interfaces and other issues. In the event of
mailfunction, this is a good place to start for trouble shooting.

Chapter 6 – maintenanCe

To keep your Compact speed log system in order, regular maintenance is
important. To take advantages of new features and performance enhancements,
you may need to update software. This section shows how.

appendix 1 – baCkground information

Here you will nd more details of how the system works and which factors are

important to know when using it.

appendix 2 – meChaniCal drawings

A picture is worth more than 1000 words! In addition to the text describing
installation, the mechanical drawings are included to allow correct installation.

appendix 3 – output formats

The system uses primarily NMEA 0183 standard. This section describes the
format of the messages used. It also describes the other digital signals in use.

appendix 4 - sending the system for repair

In the unfortunate case of a failure that requires a factory repair, the return
sequence described, should be followed.

appendix 5 - other options with the CompaCt display

The Compact speed log can be used in a number of different systems both as
a repeater and a speed log. This section explains what is available and how to
activate the options. The Compact speed log also contains a diagnostics port,
from which the user can obtain diagnostic information using hyperterm. This is
described here.

appendix 6 - support software

The Compact display is alphanumeric and as such, is restricted in the amount of
information it can display. SKIPPER Electronics AS is continuously developing
support tools to ease use of its products. The Compact system allows for the
user to extract additional information about the systems condition. This appendix
describes the software tools available that will aid this process.

INTRODUCTION

the CompaCt speed log family

___________________________________________________________________________

The SKIPPER Compact speed log family is a set of speed logs designed to have
a minimal footprint on the bridge consoles, but still keeping full functionality. This
manual covers two systems, built up of the same electronic units and wiring
methodology, with one of two sensor technologies.

a) EML224 is a system using electromagnets to generate a current
proportional to speed in the water, in one or two axis.

b) DL1 is a system using a small Doppler sensor, working in the ships axis
to provide speed through water. It use acoustic signals and measures the
Doppler shift of the particles in the water.

The hardware is compatible between systems (excluding sensor) while CD401
displays its version CD401XX-XB or later. However the code (code = software

activation code) will be different and can be supplied from SKIPPER for retrot.

1. The mounting; Either a sea valve or tank. Welded to the bottom of the hull
with the correct orientation.

2. The sensor; A speed sensor device designed to t into the mountings.

3. The Electronic unit (JB60CD); The JB60CD allowing the EML 224

Compact (EML224 Compact = Compact speed log) to be powered and
interfaced to the other navigation systems using digital standards.

4. The CD401XX Compact display; An alphanumeric display unit allowing
the bridge staff to view the data.

The EML 224 Compact (EML224 Compact = Compact speed log) is unique in

its simple, yet exible way to display vital data in almost all conditions.

CHAPTER 1

physiCal installation

___________________________________________________________________________

Installation usually takes place in two/three phases:

1. Mounting of the hull metalwork

2. Cabling and mounting of the electronics and sensor

3. Initialisation and calibration of the system

MOUNTING THE HULL METALWORK

This must happen in dock and care should be taken to mount the valve/tank

such that the sensor will be ush with nothing to cause turbulence near the

sensor. The sensor should be mounted forward in the vessel, preferably just
behind the bulb.

Important: Tank mountings have an orientation (an arrow that must point
forward).

The sensor is fully water tight and can be mounted in wet areas such as ballast
tanks. Please see the separate mounting user guide for more details.

MOUNTING THE SENSOR

Sensor location.

For proper operation, the sensor should be installed close to the bulb or the
bow of the ship, avoiding areas where it may be damaged by the anchor chain.
It is, of course, necessary to select a part of the hull that is submerged under all
load and speed conditions.

For 2 axis speed logs the transducer should be positioned as deep as possible
on the hull. The transmitting surface of the transducer must be installed
horizontally.

A typical recommended area for installation is fore part of the bow thruster
room.

The sea valve with sensor can be installed in a balast tank, but it is not
recommended. It is necessary to position the sensor on a hull section which will

ensure a laminar water ow for all angles of measurement. If such a at section

is not available, the shipyard must construct a suitable bed. If the vessel is
designed with a box keel, this can be used for installation of the sensor. In this

case, special length hull tting and sensor may be ordered from SKIPPER.

Before hull tting installation procedure is initiated, always check that the hull
tting valve can be properly operated and that the sensor can be removed in

the selected location. See installation manual for the valve solution for more
information.

PART POSITIONING AND WELDING

Please see the installation manual for the valve or tank. Installation may differ
between the different solutions available.

Paint the hull tting as well as the hull itself with a suitable anti-corrosion/anti-

fouling product, but do not paint :

• the protruding part of the sensor and electrodes.

• Inside of sea valve

• Moving mechanical components

SENSOR INSTALLATION

Please see the installation manual for the valve. Installation may differ between
the different valve solutions available.

The sensor can be mounted and powered in air and water. Briskly rubbing the
face of the sensor will show changes in values in the speed. It is very important
that the sensor is mounted in the correct orientation, (especially single axis

units). In a tank, the arrows should point forward. On a ball valve, the at area

should point on the port side.

Tip: Placing a large at straight pole on the at area will allow accurate

adjustment. Alternatively a laser level can be used to get accurate orientation
on a remote bulkhead.

Small errors in angle can be calibrated in the 2 axis verson, but care should
be taken to get this as accurate as possible. Each time the sensor is lifted or
repositioned, the angular offset should be checked. The orientation should be as
accurate as possible in the 1 axis version, as it cannot be adjusted electronically.

The JB60CD electronic unit has to be installed in a dry place on the bridge.

CABLING

System elements should be placed as in ”Interconnection diagram” on page

12. The sensor is supplied with 40 m of cable. This should be guided to a

dry area where a junction box (yard supply or SKIPPER part JB12) should
be used to extend the cable to the bridge. The sensor is a smart sensor and
outputs propriety NMEA messages. This standard is based on RS-422, so
cable lengths should not be a problem. The cable can be cut or extended.
However, power is sent down the cable and the sensor should have at least
16 V at the sensor junctions box to function normally. The cable should be as
follows:

OpInMan EML224/DL1 Compact Speed Log System

Page 16 of 68

Date: 2017-01-12

Electronics AS

Up to 40 m Use supplied cable
Up to 100 m 4 twisted pairs min 0.5 mm

2

Up to 300 m 4 twisted screen pairs 1.5 mm

2

Up to 600 m 4 twisted screen pairs 2.5 mm

2

Over 600 m Local 24 V supply to sensor at junction box is recommended

Although the signals on the cable are digital, it is recommended to avoid
electrically noisy areas such as pneumatics and generators.

The JB60CD electronic unit is mounted on the bridge. The Compact display is
supplied with 10 m of cable which can be extended to max. 20 m. This cable is
connected to the JB60CD electronic unit connector J300. The sensor cable is
connected to the JB60CD electronic unit connector J200. External inputs and
outputs are connected to the connectors J301 and J400 as shown in diagram
on next page ”JB60CD Interconnection Diagram” on page 18.

POWER

Power to the electronic unit (JB60CD) supplies power to the whole system.
The user has the option to use either or both AC 110-240 V, or DC 20-36
V supplies. Both can be connected at the same time. The JB60CD has
automatic fuses which, if tripped, will reset when the fault is removed.

THE DIGITAL INPUTS AND OUTPUTS

(alarm, pulse, dimming)

The digital inputs and outputs of the system meet the standard requirements
for IEC 61162-1. Inputs and pulse outputs are optoisolated as shown in

“JB60CD Connection methods” on page 20. To make these work, it is

necessary to apply a voltage and a resistance in series to the (XXXXX)A pin,
as shown. The nature of this type of connection is such that the installation
requires an external voltage (5-24 V) to function. A positive voltage is required
on pin marked (XXXXX)A. GND or negative on pin (XXXXX)B. Common alarm
output uses a standard relay are COM (8), NO (9), NC (10), on J400.

Page 17 of 68

OpInMan EML224/DL1 Compact Speed Log System

Electronics AS

THE PULSE OUTPUT

A single pulse output is available. This pulses at a rate proportional to the
longitudinal speed. (This is the required output for RADAR systems). The pulse
is active high and the pulse length is 60 ms. This output is located on pin 9 and
10 on connector J301 and is attached to an optocoupler. To get a signal from
this port, a voltage must be applied to pin (XXXXX) A (5-24 V). (The same as

t-out).

THE DIMMING INPUTS

Pulses of at least 60 ms on the dimming up and dimming down inputs (J400
pins 5, 6, 7) will cause the dimming to change by one level. The inputs are
optocoupled and therefore require an external voltage to operate, (4 Volt -30
Volt (typically 12/24 Volt)).

Note: If the system is set up as CD401EB/DB, the dimming input (DIMUP/COM)
are used for changing the speed direction and remote dimming is not possible.

SPEED DIRECTION (CD401EB/CD401DB ONLY)

CD401EB and CD401DB are speed log displays developed for vessels going in
both directions, like ferry boats.
On these systems the NMEA signal out to repeaters are reversable. The wanted
speed direction can be switched by connecting the DIMUP-input to Vcc and
connect a switch between the DIMCOM-input and ground. The screen will
show the same direction but NMEA VBW will change polarity. The NMEA output
sentence VMXDR is used to indicate the speed direction for the CD401EB/
CD401DB system. The VMXDR NMEA output sentence is sent if the VMVBW
NMEA sentence output is enabled.

Note: Only multi repeater should be used in this mode. These read the XDR
message and rotate the axis when requred.

If DIMCOM is left open the VMXDR output will be (backward direction):
$VMXDR,A,180,D,SPDD*hh<CR><LF>
If DIMCOM is grounded the VMXDR output will be (forward direction):
$VMXDR,A,0,D,SPDD*hh<CR><LF>

A small arrow symbol is used in front of the STW text on the screen to indicate

the congured vessel direction.

CHAPTER 2

setting up the CompaCt display

____________________________________________________________________________

PRINCIPLES

The CD401XX Compact display is a exible dot matrix LED display designed

to display navigation data. The display can be user programmed to show most
kinds of numerical data, from NMEA messages or self generated. It can also
be used as a primary sensor display for speed logs showing the speed values
produced by the sensor or as a simple repeater. The Compact speed log system
with its electronic unit (JB60CD) meets all the requirements of a primary device,
both functionally and electrically. On its own, it meets the requirements as a

repeater. The Compact display has three user denable alphanumeric displays,

each allowing up to 4 parameters to be displayed. When the device is used as

a primary device, some of these screens will be xed.

RUN SCREENS

The unit starts up in run mode. By pressing MENU button, the preset user
screens can be selected. Some of the menu screens (i.e alarms) are also
available in the run mode. The unit can be dimmed in any of the run screens

using the up (↑) and down (↓) buttons. If Trip/Total are selected as a displayed

parameter, they can be toggled using the SET button.

SETUP SCREENS

To change the setup of the Compact display, the user must simultaneously
press MENU and SET. This will give access to a menu system allowing the

user to scroll up and down the sub-menus and functions using up (↑) and down
(↓), and SET to select. To move to the previous menu, the MENU button must

be pressed. The middle underlined line is the selected line, the other lines are
dimmed.

The menu structure is shown in the diagram “Menu diagram” on page 28.
The menus are product dependant, only the relevant menus are accessible.
However, some menus are always available. To leave the menu screens and
return to the runtime screens press and hold the MENU button.

ACTIVATING THE RUNTIME SCREENS

The system has three user denable screens. Screen 1 may be locked in
some congurations. In addition, the user can make the most common setup

OpInMan EML224/DL1 Compact Speed Log System

Page 24 of 68

Date: 2017-01-12

Electronics AS

screens available. The screen menu allows the user to congure and choose
which runtime screens to be included in normal operation. UP (↑) and DOWN
(↓) buttons will scroll to the available screens. By using the SET button, the

user can control each individual screen to ON or OFF. Screens set to ON are
available to be displayed by pressing the MENU button. Screens set to OFF will
not be displayed.

ON

OFF

CONFIGURING OF DATA SCREENS

The three user programmable screens can be set up using the conguration

(CONFG) menu. This submenu allows the user to select one of the three
displays. On entering the CONFG screen, the user can change the data type to

be displayed in each of the 4 screen positions. Up (↑) and down (↓) will change

the data type, SET will move to the next screen
position. The screen layout will depend on the
selected data type. Up to 4 lines of text and data
can be displayed on each screen. Placing TXT in
the bottom 4th line or 3rd and 4th line will cause the
data to spread out showing fewer data points. The
system will not allow you to mix speed data from
different sources on the same screen. Having 2
TXT lines after each other will also rearrange the
positioning.

Note: The Compact speed log system needs one screen which indicates

just the primary data. This screen is xed and cannot be adjusted.

The non-active parameters will continue showing the dimmed title data, when
not selected.

SETUP OF INPUTS AND OUTPUTS

The system will allow many NMEA formats to be displayed:

VMVBW Speed long, trans, forward water speed
VMMTW Temperature (water)
VMVLW Trip/Total (distance sailed)
VMVHW Speed through water (resultant)
DIAG Diagnostic output (all others deactivited)

VMXDR Vessel (sensor) direction (CD401EB only)

VMALR Alarm messages

Denitions of sentences are available in “Appendix 3”

on page 56.

The system will automatically update recognised
formats. If the user wishes to output NMEA, the user
can select the NMEA sub menu in the SETUP menu and

move to the different formats using the up (↑) and down
(↓) buttons. Each format can be activated/deactivated

using the SET button.

AVERAGING

Each speed log type has some lters to ensure stable
and correct data. The averaging lter takes a number

of measurement pulses and makes a rolling average of
these values. The longer the averaging is, more stable
the data will be. However, the slower the system will
respond to changes.
The Compact speed logs have a minimum value of
10 seconds. If the system seems unstable at times, increasing the average

time will reduce the uctuations. However, the ltering is time based and as it

increases, the response time of the system will decrease.

CHANGING THE BAUD RATE

The NMEA 0183 (IEC61162-1) standard is 4800 baud. Some vessels run with
higher baud rates. 4800, 9600, 19200, 38400, 57600 and 115200 baud rates
can be selected in the baud page of the setup menu. This page contains two sub
menus, one for the sensor and one for the NMEA port. It is recommended that
the sensor is kept to 4800, as this speed is robust with longer cables. To switch
between sub pages, the SET button is used. The baud rates become active
when you leave the baud page.

DL1 MODES OF OPERATION

(DL1 only)

The default mode of operation is designed to work in nearly all conditions. Other
modes are available to give better accuracy in deeper water or to measure water

without bottom inuence in very shallow water (down to 2 m), standard is 3 m.

Setting 1 is for shallowest data, and the higher settings gradually increase the
depth (max 12.5 m).

NOTE: Wheelmark requires measurement possibility to 3 m depth.

DEMO MODE

A demo mode is available, and can be activated in the diagnostics menu. Three/
four modes are available:

Mode 1; is a dynamic demo mode taking the present value as the start point
and slowly varying all the available values.
Mode 2; is a static demo mode taking the present values and keeping
them active.

Mode 3; is a xed speed longitudinal 5 kn, transversal 1 kn.
Mode 4; (DL1 only) Adjusting the speed in this mode will cause the

DL sensor to transmit acoustics with a frequency offset equivalent to
the speed you enter. The second channel will receive that signal and
process the data proving the system is working. This will test the whole
system. To activate/deactivate or change speed in this mode you must
press SET.
When the demo mode 1-3 are active, the sensor signal is ignored, and the
screen will indicate the demo state with a blinking S in the upper right corner
of the screen. The user can turn off the demo mode from the demo screen by

pressing down (↓) button until OFF is shown in the screen, or the demo mode

will turn off automatically after 10 hours.

ALARMS

The Compact speed log does not contain any alarms except for Common Alarm
(Power failure) That is connected to the Relay output J400 pins 8,9 &10. As
there is no requirement for any other alarms, these have been removed to
conform to recent changes in standards

CHAPTER 3

Calibration

___________________________________________________________________________

THE PRINCIPLES

Calibration of a speed log involves nding the

mounting angle of the sensor (heading offset)
and the speed error at various speeds.

If the vessel has a laminar water ow near

the sensor, a single calibration point will be

sufcient. If the ow changes with speed,

(due to the friction of the hull, or nearby
constructions) then extra calibration points will
be required. The sensor is mounted on a pole
that can be turned to adjust the angle. This may result in a small angular error.
This can be calibrated away in the 2 axis version, but not in a single axis version.
This should be done before the main calibration procedure is performed.

Full calibration is designed to ignore water current effects. The procedure

requires the vessel to sail a xed length track at a constant speed. To remove

the current and wind effects, the same track should then be sailed in the
opposite direction at the same speed. The average of these tracks will be used
to calculate the speed difference between the real speed (measured using the
actual distance and the time it took), and the measured speed (using distance
from the sensor and the time it took). This procedure must be performed at least
once and then other speeds checked with the GPS.

Figure 3.1

If necessary, the procedure should be repeated at different speeds. SKIPPER
recommend that calibration is performed at a low speed and a high speed. If the
user is not able to turn the vessel and is sure there is no current, the calibration

procedure can be stopped after the rst leg and saved as a calibration point.

This will give values that are correct for that particular condition. (If current is
present, the speed through water will contain an error).

Reducing heading errors. New generation sea valves can be manually
adjusted to ensure the sensor is correctly aligned. Alignment and heading
offset are directly connected. To minimize the offset, the sensor should be
mounted pointing ahead.

• Tank mountings have ahead marks on both the tank and the sensor
insert.

• Sea valves have either a mark on the top ange or a at mark on the port
side of the pole which when a at object is placed against this, will point
fore/aft (gure 3.3).

SPEED CALIBRATION MODES

The EML224/DL1 Compact has two modes of speed
calibration:

1. Manual

2. Semi-automatic

Manual mode

The calibration – (MANUL) menu will allow the user to
adjust the heading offset (*see note below), and the speed

calibrations individually. Up (↑) and down (↓) adjust the

highlighted parameter. SET moves to the next parameter.
The data showing the result of the change will be displayed
dimmed on the same screen (offset or speed). On the 3rd
press, the lower value will change from Measured or Raw
resultant value (Mrs) to Calibrated resultant (Crs) to allow the
user to check the result of the change.

Procedure

When entering the manual mode, you will be presented with
the offset value. This is the mounting angle of the sensor. The
bottom line shows the measured offset at this moment. Adjust
the midlle value until the bottom value is near zero. Note the
bottom value has a long average, and you may have to wait
for up to a minute for the value to stabilise.

*Note: This function is only available in dual axis systems.

Hint: Pressing down (↓) and SET together will change the current selected

value to the resultant value, or to zero, saving time when adjusting.

Pressing SET moves you to the next speed calibration. Enter the real (R) speed
and measured (M) speed, (the measured speed can be seen on the bottom
line). The calibrated value can be checked by pressing SET one more time.
Repeat this process at as many different speeds as necessary.

Semi-automatic mode

The calibration – AUTO menu will take the user step by step through the
calibration menu. The user may follow the steps presented on screen. First

drawing a line on the chart system, as shown in gure 3.1 and 3.2.

*Note

• The line should be sailed at constant stable speed and
the line should represent at least 5 minutes of sailing at
the current speed.

• Leg length setting. (Adjust the length to match the line
drawn on the chart).

• Start rst leg. (The vessel crosses point A at the
calibration speed, towards point B).

• Stop rst leg. (The vessel reaches point B on the chart
and turns to sail the line in the other direction).

• Save rst leg.(If the presented speeds look correct,
save the leg and continue).

• Second leg, option. (If you do not have the possibility

to turn the vessel, you can use the rst leg data directly.
If the rst leg data is of poor quality, you may not be

given the option to continue).

• Start second leg. (The vessel crosses point B sailing
towards point A, sailing at the same speed as leg 1).

• Stop second leg. (Press as the vessel passes point B)

• Calibration result and save option. (The user can

decide to accept or reject this calibration, and in which
memory position to save it).

The user may decide which of the 10 calibration points the calibration will be

saved in. The screen will display the rst available position on the table, or

overwrite from zero upwards.

*Note: The single axis version (CD401E1/D1) of this product does not have the
transversal axis available and will not require offset calibration. However, it is
highly important that the sensor is mounted pointing forward. If mounted in a
valve, the pole can be rotated whilst moving the vessel against any current to
maximize the longitudinal speed. This should be ahead.

*Note

CHECKING THE SPEED CALIBRATION

To check that the calibration points are not too far from the ideal linearity, the
Calibration – GRAPH menu will plot the calibration points on the screen. The

user may use up (↑) and down (↓) to select a calibration point and then adjust

that value by pressing SET on the relevant point. The MENU button will return
you to the GRAPH menu again.

Calibration should occur or be checked whenever the sensor is moved, or a
new sensor is mounted. If there is growth on the sensor over time, the speed
may be reduced slightly. The system should then be re-calibrated.

Note: If a new sensor is mounted, the calibration in the Compact speed
log may be useable. However, it should be checked.

WATER TEMPERATURE OFFSET

An offset can be added to the measured water temperature from the DL1
sensor. The calibration is a linear offset to the measured value. The calibration
– (TEMP) menu will allow the user to adjust the water temperature with an
offset value. Both calibrated (C) and measured (M) temperature are shown on
the screen.

CHAPTER 5

CheCking out your system

___________________________________________________________________________

Certain conditions may effect the results of your system. The EML may with
time, reduce in speed due to growth on the metal pins. This can be calibrated
away (should be cleaned regularly).
The DL1 system requires less maintanance.
The DL1 system, by default, measures the speed through the water from depth

0.25 m to 3 m. If the water is shallower than 3 m, an element of the bottom speed

may inuence the results. This may be improved by changing the settings to

position 1. The Doppler measurements in the DL1 will be affected by water
temperature. However, this is compensated internally. Both systems may suffer
from reduced performance in high seas or in water containing many bubbles.
The EML may see a slightly reduced speed in area of extreme fresh water
<5 ppt salinity.
If you suspect something may be wrong with your Speed Log, the system has
possibilities to perform self diagnostics. This is available in the diagnostics
menu. In addition, an up to date diagnostics guide can be downloaded from
the support pages of www.skipper.no. Also, a SKIPPER service software is
available for download providing diagnostic support.

SELF DIAGNOSTICS

The Compact speed log contains some diagnostic features to enable the user
to decide which part of the system is failing. The last 20 errors are stored in
the system and can be downloaded using the diagnostics port. If the error is
serious, the system will cause a general alarm (if activated), and restart itself.
Error numbers can be found in “Appendix 5” on page 58.

TEST POINTS WITHIN THE SYSTEM

In addition to the internal system testing, it is also possible to connect a PC with
a COM port to the 9 pin RS-232 ”COMPACT” DSUB in the JB60CD electronic
unit. By using hyperterminal, many additional features can be checked.

It is also possible to see what is happening within the system by observing the
LEDs inside the JB60CD electronic unit. (See diagram on ”3) JB60CD Cabling

diagram” on page 50).

Here you can check if the sensor is operational.

LED Colour Description

LD 100 Green Flickers with each measurement.
LD 200 Green Flickers with data coming from the EML sensor.
LD 302 Red Flickers with data being sent to the sensor (not so

common).

LD 301 Green Flashes with each NMEA out transmission to navigation

system.

LD 300 Red Flashes with data arriving from the navigation systems.

NOTE: The LEDs will work even if the NMEA inputs are connected with the

wrong polarity. In the correct conguration, they are typically on and icker.

LOGGING DATA

No internal data logging is available, however, a diagnostics NMEA can be
logged on the standard NMEA port, or on the COMPACT plug in the electronic
unit (JB60CD).

maintenanCe

___________________________________________________________________________

ROUTINE MAINTENANCE EML

If the EML 224 sensor begins to underestimate the vessels speed, there may
be growth forming on the pins. These pins are made of a resistant, anti-rust
metal. If the unit is powered off, or the vessel is stationary for longer periods of
time (particularly in warm water), the growth may occur. This can be carefully
removed by lifting the sensor if a valve is installed, or by divers or in dock.
The pins must have electrical contact with the sea water, and MUST NOT be
painted. The system may be unstable for up to 6 hours after the pins have been
cleaned while a new oxide coat forms. The pins of the EML sensor should be
typically cleaned every 6-18 months depending on conditions.

ROUTINE MAINTENANCE DL1

The DL1 Doppler system requires virtually no maintenance except cleaning
when docked, and occasional greasing / testing of the moving parts of the valve.

CHECKING YOUR VERSION

If the info screen is activated on the run screens, the system type and software
version can be read from there. Otherwise the same screen can be obtained in
the diagnostics menu. The system type will be one of the following:

CD E1 EML 124 compact display 1 axis
CD E2 EML 224 compact display 2 axis
CD EB EML 124/224 compact display ”Reversible” mode
CD LR Log repeater compact display
CD MR Multi repeater compact display
CD MB Multi repeater compact display ”Backwards” mode
CD D1 Doppler Compact display 1 axis

The system will be locked to one of these setups, but can be changed to one
of the other systems (with an additional cost) using a code (see ”Appendix 5”

on page 58).

SOFTWARE UPGRADE

The system is undergoing continuously improvement, and periodically new
software will be released. These can be found at the download area of the

OpInMan EML224/DL1 Compact Speed Log System

Page 42 of 68

Date: 2017-01-12

Electronics AS

SKIPPER website (www.skipper.no) and may be downloaded and the system
upgraded using a PC connected to the ’Compact’ COM port in the electronic
unit (JB60CD). Alternatively a chip can be supplied (with an additional cost)
with the new software. This is changed by removing the backplate of the
display unit.

To upgrade the software, select which com port is to be used (for JB60CD
electronic unit ’Compact’ DSUB use ’COMPACT’ port, and select SENSR for
upgrade). Ensure the line is clear by removing power from the EML sensor.

Press set and restart the system. The unit will wait for new rmware for two

minutes. After that it will start with the existing code. You may then start the
SKIPPER service software (downloadable from the SKIPPER website), select
the Compact display window, and then use the upgrade button to upgrade the
unit.

MASTER RESET (FACTORY DEFAULT SETTINGS)

The factory default settings can be restored by performing the following
operations:

1. Select CODE in diagnostic (DIAG) menu.

2. Press the SET button (Note: Do not change code value, just press the SET
button.)

The unit will now restart with factory default settings.

Note. On Compact speed log systems, this will also reset the stored
calibration values. We therefore recommend to write down the values before
attempting this.

baCkground information

____________________________________________________________________________

EML224.

The EML224 Compact system works using Kirchoffs right hand rule (based
upon Faradays law of generators) which states that a conductor (sea water)

moving through a magnetic eld (generated in sensor) will produce a current
orthogonal to both eld and movement. So movement of the vessel through

sea water with at least 5 ppt salinity will produce a current across the pins
orthogonal to the ships motion.

This minute current is measured and converted to a speed. This is formated into
proprietry NMEA VBW format and sent to the EML 224 Compact display which
applies an angular correction for both transversal and longitudinal speed, and
then a scaling factor is applied for the resultant speed.

Inside the EML224
smart sensor.

OpInMan EML224/DL1 Compact Speed Log System

Page 44 of 68

Date: 2017-01-12

Electronics AS

The Doppler system operates by sending a known frequency sound into the

water, and listening to the reected echo from the minute particles in the water.

If the particles are moving towards the sensor, the frequency goes up, if away,
the frequency goes down. By having two beams at 30 degrees from the vertical
we get 2 frequency values, one plus, one minus, and these can be adjusted to
show the speed of the vessel in the horizontal plane.
As the amount of particles in the water can vary, the system ensures it has
optimal signal return by adjusting the power and length of the sample, depending
on depth.

How calibration works.

Calibration is piecewise linear, i.e. a linear line is plotted from calibration point
to calibration point (sorted by size) and this linearity is applied to the incoming
values. This can be seen on the graph screen.

Entering the code on the CODE page will activate/deactivate the option.

NOTE: It is important to note that option codes are unique for each
individual unit and will not work on other units.

INTERFACING WITH YOUR DISPLAY

It is possible to retrieve conguration and diagnostic data from the Compact.

This can be performed by connecting to the electronic unit (JB60CD) ‘compact’
port, or directly through the NMEA port. In this way, error messages can be
retrieved when required.
The SKIPPER Service software are available if required.

The following messages exists:

• $PSKPVMPCGTER,x if x = 0 = Last error, other = whole table

• $PSKPVMPCDEMO,mm,lw.ll,tw,ta,lb,tb,ab,tmp,trip,total

where:

• mm = 0, auto.

• mm = 1, uses the following values: (see table)

• mm = 2, turn off.

Table showing mm = 1 values

lw longitudinal water value <xx.xx>
tw transversal water value <xx.xx>
ta aft transversal water value <xx.xx>
lb longitudinal bottom value <xx.xx>
tb transversal bottom value <xx.xx>
ab aft transversal bottom value <xx.xx>
tmp temperature <xx.xx>
trip trip distance value <xxxx>
total total distance value <xx.xx>

It may be necessary to remove other inputs on the same line (i.e remove power
from the sensor).

ERROR MESSAGES

Symptom: Screen shows error instead of data.
Reason: If no data is received from the sensor, the screen will show ‘ERROR’.
Fix: Check the LEDs are ashing in the Electronic unit. LD 100, LD 200.

• Connect a PC to the RS-232 Diagnostics Sensor/‘HEAD’ connector in the

electronic unit. If the system is sending $PSKP.....ERRBOR or similar, the

voltage to the sensor is too low.

• Check if the Voltage on J200 p1 p2 is 18-25 V.

• Check if the voltage in junction box is >15 V, if not, twin pairs to get higher

voltage. (If yellow/orange pair is not required and can be disconnected and
used to parallel the power).

• If no, or garbled data, check that the pairs are connected correctly (A/B).

If you suspect you have a problem within the CD401 unit, an error message table
can be retrieved from the unit by sending the message $PSKPCPPCERROR
<CR><LF> from the ‘compact’ connector of the JB60CD or the NMEA input on

repeater. The returned format is in the form: ID, number of errors, last error, rst

18 errors.

$ PSKPERRORTABLE,19,32,100,<Error18>,…,<Error1>

< Identier >,<Number of errors(19)>,<Last Error after 18 errors(32)>,<rst 18

error>,

This format shows a table of 20 numbers, where position 1 shows the number

of errors stored. The errors are stored on the ash memory and will be retained.

If you suspect an error, download the messages, then reset the error messages
and try to perform the same error condition again. If successful, download the
errors again and then check the list below. In addition, the self test values 0-4
can be used to check the main peripherals of the unit.
