Consilium Navigation SAL-R1 Performance

Introduction
The SAL R1 is an acoustic watertrack speedlog based on correlation technique. The concept
consists of a transducer, an Electronics Unit (ELC), repeaters (SD-indicators) and optionally an
extension unit (LPU / LDU). This is in full analogy with R1's predecessor, the Imcor2.

The transducer is very versatile in its possible mounting arrangements. It can be directly fitted into
existing SAL 24 bottom parts to allow a quick updating of an old log system, without a special need
for dry-docking when installing the SAL R1 system.

The SAL R1 speedlog has been developed as an economical unit for accurate measurement of ships
relative speed and distance. This is achieved by using a combination of advanced microprocessor
technology and long experience in the design of logs for merchant shipping and navies around the
world.

The sections of this manual are grouped in the following manner:

• Section 1 (this section) is a short introduction and safety instructions.
• Section 2 contains functional and technical description together with system design. This section
also lists all parts of the speedlog system
• Section 3 contains technical specification.
• Section 4 describes the operating menus.
• Section 5 contains useful information about installation of bottom parts and transducer.
• Section 6 covers installation of Electronics Unit and wiring to this. This section also describes
DIP switch and jumper settings and how to download new software.
• Section 7 gives detailed information about SD1 indicators, including installation procedure.
• Section 8 gives detailed information about SD2 indicators, including installation procedure.
• Section 9 (optional) contains detailed information about the R1P-board.
• Section 10 (optional) contains detailed information about the extension unit in the system. This
could be a Log Processing Unit (LPU) or a Log Distribution Unit (LDU).
• Section 11 defines IEC 1162-1/NMEA 0183 messages used in the log system and provides
useful information when connecting external users to the IEC 1162-1 network of the system.
• Sections 12 to 15 are reserved for future use.
• Section 16 describes the calibration procedure and shows a calibration protocol.
• Section 17 specifies your scope of supply.
• Section 18 contains information for trouble shooting in field situations and also reports sheet for
trouble reporting to Consilium Navigation AB.
• Section 19 is intended for commissioning documentation. Updating information here and
reporting information back to Consilium Navigation AB will aid giving good support in case of
trouble and will thus aid in getting most performance / reliability out of the system.
• Section 20 contains installation, service reports and service request document.

1. Introduction
The SAL-R1 system consists of a transducer (TRU), an electronics unit (R1 ELC) and repeaters,
indicators etc. Extension unit between the ELC and repeaters is optional. A standard SAL-R1 can be
connected to any piece of equipment reading NMEA serial data.

The signals from the transducer are processed by a microprocessor within the electronics unit, and are
fed to one or more speed and distance indicators, and to other user equipment.

3. Optional equipment
3.1. Indicators
The SAL-R1 speed log system is delivered with an SD1-2 WT speed and distance indicator. If the SAL-
R1 is part of a larger SAL860 system other indicators may be more useful. All indicator versions are
presented in the section on the relevant indicator.

All SD indicators may also be provided with Bulkhead Mounting Box and Sealing Frame Kit for mounting
on open decks. Also available is an SDP converter from 230 VAC to 24 VDC or 48 VAC to power
indicators when only 230 VAC is available.

SD and DD indicators all have digital presentation of speed. If an analogue presentation is desired an
SIA instrument may be added. However, these instruments require an R1P to be mounted on the R1 or an
extension box in the system.

3.2. R1P
If the R1 has an extra serial-to-pulse converter board, R1P, mounted (inside the ELC) data can be output
as pulses (four outputs 200 p/NM, one output 20 000 p/NM, one forward/astern indicator ± 5 V) and
analogue voltage (one output 0,1 V/knots).

When an R1P is mounted the R1 becomes totally compatible with an Imcor2 and can replace the Imcor2
in any installation. If an R1P is present in your log system, this converter board is presented in the
section on R1P.

3.3. Extension box

When the ELC is installed far away from the bridge - e.g. in the forepeak - it is favourable to draw only
one data cable from it to the bridge. On the bridge, or in its vicinity, an extension box is installed. This
could be an LDU or an LPU.

The extension box receives serial data from the ELC and distribute this as pulses, analogue voltage and
serial data to all other equipment on the bridge and elsewhere. If any such equipment is part of your
system, the relevant extension box is explained in detail in the section on extension box.

5. Basic concept
The transducer will send two parallel signals into the water. The signal to the forward crystal (TRU cable
1 and 2) will have a frequency of 3.840 MHz and to the astern crystal (TRU cable 4 and 5) 4.194 MHz.
Output amplitude is approximately 25 V in 100 ohms, giving an electrical output of 3 W.

The lobe function is very narrow, and no side lobe contributes significantly to the signal content. It is
thus fair to assume that the beam goes perpendicular to the surface of the crystal. Only the main lobe is
considered in the following discussion.

Correlation technique is used to calculate the time delay between the signals. The operating frequency,
centred on 4 MHz, has been empirically optimised. It is a trade-off between signal decay, lobe function
and transducer design.

SAL-R1 System 701835D0.DOC
The signals from the transducer move out into the water. They are reflected by objects and move back to
the transducer. The effective speed for the pulses is thus half the speed of sound in water. The time
delay for signal echo is thus proportional to this speed multiplied with the distance to the object. The
transmitpulse length gives a volume, which may give echo at a given delay. Figure E shows the
measurement water volume, which may give an echo for a transmitpulse. The R1 makes an integration of
the signal for a given time. This is equivalent of the water volume moving outwards during this time at
half the speed of sound.

The signals thus received can be regarded as two ”snapshots” of the flow of particles under the ship.
Using correlation technique it is possible to compare how much the signals differs in time. Knowing the
distance between the crystals it is easy to calculate the speed of the particles and hence the speed of the
ship through the water.

5.1. Acoustical signal

R1 is used to measure relative speed in the boundary layer (see section on calibration) using acoustic
correlation technique. The signal is measured in a water volume at a chosen distance below the hull. The
echo signal is intensity modulated by the particles that traverse the water volume below the sensors.

Correlation technique is used to calculate the time delay (t) between signal S1 and S2. This is called
temporal correlation. If the sensor is based on a one or two-dimensional array the displacement
calculation is called spatial correlation. A number of algorithms have been developed to measure this
delay / displacement. The extreme of the correlation function maximises the similarity of the signals. This
delay is called τ0 (tau), see figure E.

Delay (τ ) is two samples

samples

Figure 6: Time displacement between signals.

5.2. Correlation functions

The correlation function is used to measure the displacement between the two channels. One often-used
correlation function is the cross correlation function (CCF). It is defined as:

∑ s1(i) * s2(i + τ )
ccf (τ ) = i

where N is the number of summation points. The speed (ν) is then calculated as

D
v=
τ0

where (D) is the distance between the sensors, and τ0 is the displacement corresponding to maximum
correlation. The algorithm used in SAL R1 is slightly different, and gives a minimum for the maximum
correlation coefficient, see figure F.

In figure F the minimum correlation value (maximum correlation) corresponds to a time delay of two
sample intervals.

5.3. Boundary layer and calibration

The water close to the hull is moves slower than further away. This layer with lower speed is called the
boundary layer, see figure below.

At boundary layer edge:

(Relative water speed = U)

Figure 8: Boundary layer.

The SAL R1 measures speed close to the hull, and may thus measure a lower speed. When the ship is
shallow water, the boundary layer may be different from normal. This physical effect will affect all logs
measuring relative speed.
The positioning of the TRU is very important. The water flow below the TRU must not be turbulent or
affected by scew water flows. Turbulent flow gives no common signal between the two channels.

SAL-R1 System 701835D0.DOC
Calibration is needed to compensate for this speed change. The calibration may be set in one point,
called single point calibration, or more than one point, called multiple point calibration.

5.4. Speed filtering

The inaccuracy of the speed value depends on the time constant. The correlation speed log inaccuracy
depends on the correlation coefficient and the measurement distance. A longer measurement distance
will give a more accurate value. The selected time constant is a compromise between fast response and
stable readings.
In lower speeds, the relative time-delay change is large when the speed changes. The relative time delay
change from 1 to 5 knots is thus equal to the change from 10 to 50 knots. In order to keep the log from
loosing track of the speed in the low speed range, the algorithm uses a number of fix delays. The speed
estimate is then interpolated.

5.5. Distance calculation

The speed value is integrated into distance. The distance information is sent to indicators as serial
message for synchronisation of the total speed through water distance data.

5.6. Adverse conditions

It is important to remember that what the R1 measures is actually the speed of a discrete number of
reflectors moving in a small water volume under the hull. In order to interpret the echoed signal it is
anticipated that the particles are moving parallel to the vessel axis. If the transducer has been installed at
a non-preference location of the hull the water flow might be turbulent at the site of the transducer.
Under these conditions there is no guarantee for the log to work. See section on installation of bottom
parts for correct transducer installation.

In the low speed range, the distance travelled per time interval is low yielding limited information to the
correlation function. This influences accuracy and may impose lost speed track conditions.

The log may encounter problems to measure when the ship moves in water with high particle content.
This depends on that many particles give "foggy" reflections, which makes it difficult to see the same
pattern at the true delay.

6. Electronics cabinet
6.1. User input & output
The SAL R1 has a two times 16 character LCD. The LCD is used to inform the user of the current status
for the log. Four green LED’s on the front panel of a SAL-R1 marked ”Corr.”, ”Sgn.”, ”Tr1” and ”Tr2” is
used to give status information. There are four push buttons named "menu", "enter", "plus" and
"minus", used to interact with the R1 menu system.

”Tr1” and ”Tr2” are lit when the transmitter of the ELC is active and working properly. ”Sign.” is lit when
the signal conditions from the transducer are good or better. ”Corr” is lit when the correlation coefficient
is good or better.

6.2. Data transmission / reception

Data is sent from the SAL-R1 as serial NMEA messages on a standard RS 485 output marked NMEA ”A”
and NMEA ”B”. A maximum of 10 repeaters or other instruments can be connected. Three of these
repeaters can be powered directly from the log when using SAL SD-indicators. The fuse is for this 10-30
VDC power.

NMEA-messages are also available through RS232 on the 9-pole Dsub-connector. It is used for data
logging and software updates. Thus it is possible to read out information directly on an ordinary PC
using for instance a Terminal Emulator program. Note that the pinout differs from the PC-standard, and
can be found in the fault localisation chapter.
If pulse or analogue output is needed, an optional unit R1P may be fitted to the ELC.

6.3. Sampling control

Sampling is controlled by three timing factors: Transmitpulse length, Echo time and Integration time:

SAL R1 sampling

Transmit pulse
Echo time
Integration time
Figure 10: Sampling
One sample-period starts when the transmitpulse is emitted for the time T (i.e. Transmitpulse length). As
already described the signal is sent out into the water and reflected against particles. Both crystals in the
TRU transmit and receive simultaneously. The transmit pulse, echo and integration times are possible to
adjust in the SAL R1. The sum of transmit pulse, echo and integration time is software limited to 199.3 µs.
Adjusting the R1 sampling timing is intended only after discussions with Consilium Navigation. It is
included to give the possibility to fine tune installations, but may give the log bad working conditions if
used without experience. The calibration must be remade after changing sampling timing, as the
calibration factor differs at different positions within the boundary layer.
Reasons for changing the parameters may include:
• High-speed vessels may find better working conditions closer to the hull as the boundary layer is
thinner.
• Slow-speed vessels (as submarines) may find better working conditions further away from the hull as
the boundary layer is thicker.
• In very clear water with low particle content a longer integration time gives a better signal to noise
ratio. On the other hand, in waters with high-particle content a shorter integration time is preferred.
6.3.1. Transmit pulse
The length of the transmitpulse has empirically been set to 10.7 µs. Normally this value should not be
altered, unless the measurement conditions are too unfavourable for this setting.

6.3.2. Echo time

The echo time is the time the log waits until it starts to integrate the reflected signal. Its value decides
how far from the hull the log will measure. The minimum measurement distance (dist) from the hull in
millimetres can be calculated by entering the echo time in microseconds in the formula:

15
. * echotime
dist =
2
The echo time has empirically been set to 150.7 µs.

6.3.3. Integration time

The integration time sets the time the log integrates (or listens to) the echo. The echo time has
empirically been set to 35.7 µs. The thickness of the measurement volume may be estimated by the same
formula as above.
6.3.4. How to interpret the signals received
It is possible to diagnose the working conditions for SAL R1 using an oscilloscope. The figures below
show the expected signals at the test points for channel one and two (TP1 and TP2).

Time
Figure 11: Signal response under bad conditions

This is an example of how the signal looks when running the SAL-R1 in water with extremely high
particle content. No peaks from individual particles can be found. They are all hidden in a continuum of
the decay of the transmitted signal. The log is unable to measure the speed.

Figure 12: Signal response under normal conditions

This is an example of how the signal looks when running the SAL-R1 in water with a high density of
particles. Peaks from individual particles are added on top of the declining signal. The log is able to
measure the speed.

Time
Figure 13: Signal response in very clear water

This is an example of how the signal looks when running the SAL-R1 in very clear water with almost no
particles. Peaks from the very few particles present are clearly visible. The log measures the speed, but if
no particles pass by the TRU for a long period of time, it may loose track of the speed.
6.3.5. Digital filtering
When there is a high density of particles in the water this can be seen as an increase in AGC levels. To
improve the quality of the integrated signal before correlation a digital filtering is performed on the data.
This, however, increases the risk of presenting false speeds. For this reason digital filtering is used only
when the AGC levels indicate there is a high concentration of particles in the water.

Digital filtering is used when the present AGC level is higher than background noise level plus a certain
offset. The offset can be adjusted in a menu.

7. R1 software
The SAL R1 software has different working modes. This chapter describes the R1 functions seen by the
user.

7.1. Power on / software update

At power on the SAL R1 runs a special program that tests if the R1 program code present. If the code
found and correct, the R1 starts to execute in normal operation. Software program updates are also
possible to download into the R1 with this program. This program controls erase and store of the update.

7.2. Normal operation

The SAL-R1 has three processes that run in parallel: measurement, menu system and evaluation of
measurement data. It is thus possible to enter the menu system without stopping the log from measuring.
The only exception to this is test modes, where the log transmits a simulated dummy speed. The test
mode T3 may also be used by the program itself for testing the transducer levels.
The measurement process can be divided into seek and lock modes. After power on the log enters seek
mode. It seeks for zero speed (mode SZ) and based on the result of the measurement it may stay in zero
speed mode, or enter speed seek modes. The speed seek modes are seek Low speed (mode SL) for
speeds below 4 knots, or seek High speed (mode SH) for speeds above 2 knots. The seek operation is
repeated until a valid speed is found. The log then enters the locked speed modes. There are two locked

SAL-R1 System 701835D0.DOC
There is an AGC (Automatic Gain Control) for each channel on the input of the SAL-R1. It will check the
strength of the signals on channel 1 and 2 respectively and compensate the input so that the signals are
at an optimum when the log starts to sample and correlate them. A low AGC value (in mV) is equivalent
to a high amplification of the signal, and vice versa. The maximum AGC value is 2200 mV. A normal value
is 1200 to 1400 mV, whilst in very clear waters the value may approach the background noise level. To
summarise; high value indicates many particles and low value indicate few reflectors in the water. In
water with high particle content a digital filter is applied (field F) to improve signal conditions.

The LCD panel on the SAL R1 shows the working condition, speed information and signal level. The
readout uses the following field descriptors:

MM ±XX.XX ±YY.YY
FC=DDD ZZZZ:TTTT
If no valid speed is found the log enters search modes where ±XX.XX and S=DDDD share the same
position. The definition for the field descriptors is found in the table below.

7.2.1. Seek zero speed mode

In "Seek-zero-Speed-mode" the log has a predefined sampling interval and calculates a special
correlation function to estimate the speed range and detect zero speed condition. The LCD presents
information if it detects zero speed as:

SZ 0.00 ±YY.YY
FC=DDD ZZZZ:TTTT
7.2.2. Seek low speed mode
In "Seek-low-speed-mode" the log seeks for speed in the lower speed range. It has a predefined sampling
interval and calculates the correlation function corresponding to a number of discrete speeds. If speed is
found in the high end of the seek range, seek high mode is called. The values for correlation coefficient
(C) and signal quality (S) is presented:

SL S=DDD ±YY.YY
FC=DDD ZZZZ:TTTT
7.2.3. Locked low speed mode
In "Locked-Low-Speed-mode" the log has a predefined sampling interval and calculates the correlation
function corresponding to a number of discrete speeds. Interpolation is used to give better speed
resolution. If the speed is below 0.2 knots, seek zero speed mode is entered. If the speed is above 2.5
knots, lock high speed mode is entered. The LCD presents speed information in the following format:

LL ±XX.XX ±YY.YY

7.2.4. Seek high mode
In "Seek-high-mode" the log searches for speed in the upper speed range. It has a predefined sampling
interval and calculates the correlation function corresponding to a number of discrete speeds. The
values for correlation coefficient (C) and signal quality (S) is presented:
SH S=DDD ±YY.YY
FC=DDD ZZZZ:TTTT
7.2.5. Locked high speed mode
In "locked-high-speed-mode" the log has locked in on the speed and uses a feedback algorithm to adjust
sampling to track the speed. If the speed is below 2 knots, lock low speed mode is entered. The LCD
presents the speed in the following format:

LH ±XX.XX ±YY.YY
FC=DDD ZZZZ:TTTT
7.2.6. Test modes
In the test modes the log stops to measure speed. The test modes stay active until power off or the user
releases the test mode. The software to register the AGC background level also uses the test mode T3.
The transmission is then switched off and the log measures the settling of the levels.
T3 TRU SIGNAL
LEVELS ZZZZ:TTTT

Settling is stopped after 10 seconds, and the log returns to normal operation. The LCD presents normal
test result as:
T3 TRU SIGNAL
LEVELS NORMAL

If signal levels are (too) low (and the transducer may be damaged or not connected) as:
T3 TRU SIGNAL
LEVELS LOW

7.3. Menu system

Pressing the keys on the panel accesses the menu system. The LCD then presents the content of the
active menu. If no keys are pressed for 30 seconds, the menu times out to normal operation, except when
in test menus. The menu system is described in a separate document.

SAL-R1 Performance 701862A7.DOC

1 General
The technical specification in this section deals with the SAL R1 system, i.e. the transducer, the ELC,
optional R1P-board, optional signal distribution unit and connected display units.

The performance limits defined here are met provided the following has been fulfilled:
• Installation of each and every part of the system has been carried out according to the
specifications in this manual and according to good craftsmanship.
• A full calibration procedure has been performed correctly
• The system is used only to measure the speed of the water under the hull of a ship
• The log is operating within the environmental conditions herein described

2 System Performance Data

Working Principle: Acoustic correlation

Frequencies 3.840 MHz and 4.196 MHz
Measuring Distance: 75 mm - 200 mm from the surface of the
transducer, default is 110 mm
Speed Range: ± 50 knots
Speed Accuracy Relative To Sensed Water < ± 1% or ± 0.1 knots whichever is greater
Flow:
Distance Accuracy: < ± 1%

3 Electronics Unit

Speed Output: Serial data on RS 485 and RS 232 according to

NMEA0183 / IEC61162-1.
Maximum 10 SD-indicators connected.
Extra Outputs with optional R1P mounted: 0.1 V/kts. (load < 5 mA)
4 outputs 200 p/NM
1 output 20 000 p/NM
2 status relays
Power to indicators: 24 VDC to power a maximum of 3 SD-
indicators
Power requirements: 220 / 115 VAC 50 - 60 Hz
Power consumption: 30 VA nominal
Dimensions (R1 ELC): 390 × 360 × 170 mm

The ELC has one NMEA channel available on both RS 485 and RS 232 output. In normal mode
this channel will carry $VDVBW-messages with valid longitudinal watertrack speed only. When the
SAL R1 is part of an SAL 840R or SAL 860R system, the R1P board enables the NMEA channel
to include valid longitudinal and transversal bottomtrack speed in the $VDVBW-message as well as
carrying $VDDPT-messages.

4 Environmental requirements
All parts of the SAL-R1 system fulfil and are certified to meet all requirements set out in IEC 60945
edition 1996.

5 Liability
All equipment described in this manual was designed for use on board ships to fulfil requirements
specified in various IMO documents.

However, equipment may sometimes fail or work outside its performance specification due to
component malfunction or depending on other factors.

Consilium Navigation will not take any responsibility if this equipment is used in such a way that it’s
normal or abnormal function causes damage or creates situations that can be dangerous.

Figure A: SAL R1 front panel

All settings, calibration etc. is carried out using the menu system, which use the LCD and four
keys and seven combinations:
MENU These key combinations are used to go to the next menu within
MENU + the menu level. Each time the key is pressed, the displayed
menu number is incremented and the next menu is presented.
Holding down the "MENU" key and pressing down the "+"
key (plus) is equivalent to only pressing "MENU".
MENU — This key combination is used to go to the previous menu
within the menu level. Each time the key is pressed, the menu
number displayed is decreased and the previous menu is
presented.
MENU This key combination is used to go up one menu level.
ENTER:
ENTER: This key is used to step down one level in the menu system. It
is also used to accept and save the setting(s) on the lowest
menu level.
+ (Plus) This key is used to increment the chosen value or setting.
— (Minus) This key is used to decrement the chosen value or setting.

Please note that both the plus and minus keys can be used to toggle between ON and OFF in
some menus.

If no keys are pressed within 30 seconds, the menu system times out to the normal operation
menu. The only exception to this is the test menus.

2. Write and read only access

First level menus include the possibility to select read-only or write access to prevent
accidental change of parameters. Parameters may only be changed when write access is
selected. The write access is active for all submenus within the menu tree, and is reset to read
only access when returning to the top level.

3. User interface
Implementation is based on R1 revision C.. The log starts up and measures speed on its own.
The log enters the menu system when a key is pressed. The LCD readout depends on mode,
and is described below.

3.1. Initialisation
In the initialisation sequence the software checks whether the hardware is SAL R1 or
RSC860B. Timers and hardware is set-up for normal operation.
In the initial SAL R1 readout the revision is set according to the software revision. The
example below shows software version I0.
SAL R1
REV: 701823I0
In the initial SAL RSC860B readout the revision is set according to the software revision. The
example below shows software version E0.
SAL RSC860B
REV: 701823I0

3.2. Normal operation

The log in normal operation calculates the speed from the sensor signals. The log also
measures signal level from the transducer. The LCD readout uses the following field
descriptors:
MM ±XX.XX ±YY.YY
FC=DDD ZZZZ:TTTT
If no valid speed is found the log enters search modes where ±XX.XX and S=DDDD share the
same position.

4 (23)
çConsilium SAL R1 Menus Art No. 701860D0

The definition for the field descriptors is found in the table below.
Descriptor Explanation
MM Working mode
±XX.XX Sensed (raw) speed from transducer
±YY.YY / --.-- Output speed including calibration and time constant averaging.

algorithm to adjust sampling to track the speed. The LCD presents the speed in the following
format:
LH ±XX.XX ±YY.YY
FC=DDD ZZZZ:TTTT

3.2.2. Seek high speed mode

In "Seek-high-speed-mode" the log searches for speed in the upper speed range. It has a
predefined sampling interval and calculates the correlation function corresponding to a
number of discrete speeds. The values for correlation coefficient (C) and signal quality (S) is
presented:
SH S=DDD ±YY.YY
FC=DDD ZZZZ:TTTT

3.2.3. Seek low speed mode

In "Seek-low-speed-mode" the log seeks for speed in the lower speed range. It has a
predefined sampling interval and calculates the correlation function corresponding to a
number of discrete speeds. The correlation functions are averaged to improve statistics. The
values for correlation coefficient (C) and signal quality (S) is presented:
SL S=DDD ±YY.YY
FC=DDD ZZZZ:TTTT

3.2.4. Locked low speed mode

In "Locked-Low-Speed-mode" the log has a predefined sampling interval and calculates the
correlation function corresponding to a number of discrete speeds. Interpolation is used to
give better speed resolution. The LCD presents speed information in the following format:

SAL-R1 Bottom parts 701849Ab.doc

1 Introduction
The SAL-R1 system consists of a transducer (TRU), an electronics unit (R1 ELC) and repeaters,
indicators etc. A standard SAL-R1 can be connected to any piece of equipment reading NMEA
serial data.

The R1 uses the same type of transducer as the Imcor2. Consequently the installation of the
transducer is the same. This also makes it very easy to retrofit an old Imcor2 with a new R1.

NOTE: The transducer is tested with the cable as one unit. Do not cut or modify the transducer
cable. The relative speed measurement operates at a frequency where cable length may affect
performance. Consilium Navigation takes no responsibility in case of cable modification.

Figure 1: The transducer

The TRU design is shown in the figures. The channels are designed for signal transmission and
reception on 3.8 and 4.2 MHz respectively. The transformer coupling is designed for impedance
matching and crystal load tuning. The front window acts as electrical isolation for the crystals.

Production of the TRU includes trim of the beam angles. The final production test includes signal
level measurement, and beam angle measurement. The production of the TRU's depend a lot on
handicraft skill.

30 metres cable

Figure 2: R1-transducer design.

2 Location of a transducer
2.1 Introduction
It is important to remember that what the R1 measures is actually the speed of a discrete number of
particles moving in a small water volume under the hull. In order to interpret the echoed signal it is
anticipated that the particles are moving parallel to the vessel axis.

This makes the positioning of the TRU very important. The water flow below the TRU must not be
turbulent or affected by skew water flows. Turbulent flow gives no common signal between the two
channels. The flow of water below the TRU must also be smooth. If the flow is very turbulent the log
may give an inaccurate speed measurement or may not be able to measure at all.

It should be noted that a good transducer installation is of primary importance for achieving
good performance of the log system. Selecting correct transducer location shall be done in co-
operation with Consilium Navigation AB and Consilium Navigation AB must approve the selected
location!

2.2 Important rules of positioning the transducer

• The transducer should, preferably, be installed in the foremost area of the vessel, if possible in a
perpendicular position in the lower section of the bulb, close to the keel line. It may also be
installed in the forepeak or in a double bottom peak tank.
• The transducer may be installed in the aft part of the vessel, e.g. at the foremost end of the engine
room. Its distance from the propeller must be greater than 1/4 of the ship’s length.
• Install close to the keel line.
• The compartment in which the transducer is installed may be sealed by a manhole or hatch but the
compartment must be accessible for service.

• On tankers, the installation position is not to be within the Ex-area. The transducer must never
come into contact with explosive cargoes.
• The installation position is to be at least 2 m from any echo sounder transmitters and similar
devices.
• In the vicinity of the installation position, the outer skin of the vessel must be free from sudden
projections, steps and sharp edges. These will cause water turbulence and therefore inaccurate
speed data.
• Water inlets and outlets influence the flow of current, therefore the transducer is to be installed at
least 2 m forward of such openings.
• The transducer must always remain submerged, even with a minimum of cargo in heavy seas.
• Sufficient headroom must be available at the transducer position to allow for its fitting and removal
(see the chapter for appropriate bottom parts).
• The sea valve arrangement and transducer cable are not intended for permanent submerged
mounting in a waterfilled tank. If no other alternative is available a separate watertight (W.T.)
compartment must be arranged housing the sea valve/transducer assembly
The cable must be run in a watertight pipe conduit, connecting directly from the W.T.
compartment to free/dry space above sea water level (maximum draught of vessel) where the log
electronics unit (ELC) is normally installed.
• Do not cut the cable! Warranty is void if cable is cut!

3 Maintenance of Bottom Parts

Each bottom part assembly incorporates a zinc ring, which acts as a sacrificial anode to prevent
corrosion of the transducer and bottom parts. This zinc ring should be checked, and changed if badly
corroded, each time that the ship is dry-docked.

Material: Structural Steel

type SS-Steel 2172-00
(SS=Swedish Standard)
or DIN st 52-3
Max Carbon 0.2% in the cast

Figure 3: Bottom flange.

4 Mounting set single bottom (MSSB)

The mounting set single bottom assembly is suitable for small ships, which can be easily moved out of
the water onto a slipway for access. It may also be used for ships where insufficient space is
available for fitting a sea valve.

The components of the MSSB assembly are supplied in a kit form for assembly in the ship. Before
starting assembly check the contents of the kit against the packing list. Figure 4 shows how the
components fit together. The complete assembly with its overall dimensions is shown in figure 5.

4.1 Transducer housing

The TRU housing must first be welded into a hole cut in the ship bottom.
1. Cut a circular hole, diameter 170 mm (+10 / -0 mm) at the selected TRU position.
2. Weld the TRU housing into the hole; ensure that it is positioned with the stud holes in the top
flange along the fore/aft and athwartship lines (see figure 6). A welder holding qualifications
approved by the applicable classification society should carry out welding work.
3. It is important that the outer (bottom) surface of the housing should be flush with the
hull. The welded joint must be ground smooth and flush with the hull. There must be no sharp
edges to interfere with the water flow over the transducer.
4. Fit the zinc ring and the guide ring into the bottom of the housing and secure with four FS10 × 35
screws.
5. Screw four PS12 × 55 studs into the top flange of the housing.

Figure 18: Orientation of transducer tube

7 Mounting set SAL 24 installation (MSSAL)

The mounting set for SAL 24 installations includes all items required to convert existing SAL 24
installations to accept the lmcor2 transducer. The new transducer may be fitted without dry docking
the ship; dry docking is preferable, however, as this also allows new external parts to be fitted.

Three basic types of SAL 24 installations are currently in use:

1. Single Bottom.
2. Double Bottom Old (before 1977).
3. Double Bottom New (after 1977).

Note. Where the EPTM (Electric Pitot Tube Manoeuvring) equipment head is installed, the
Imcor2 conversion is not directly possible. The EPTM head must first be replaced with a standard
SAL 24 head.

This section describes the conversion procedure for each type of installation both with and without
dry docking.

7.1 Transducer connecting tube

The length of the transducer connecting tube should be the nearest size to the length of the old pitot
tube (see table 1 in chapter 6).

7.2 Installation without dry docking

The procedure described below applies to all three types of SAL 24 installations. The conversion kit
supplied comprises the necessary parts to convert all three types of SAL 24 installations. The kit also
includes new external bottom parts, which cannot be fitted without dry docking. It is recommended
that these parts should be fitted when the ship is next dry
docked.

7.2.1 Removal of existing SAL 24 pitot tube

Before attempting to remove the old pitot tube, check that the sea valve appears to be functional.
Although it is not possible to check it completely with the sensor in place, at least ensure that the
valve wheel is not seized with corrosion but is free to turn by hand.

1. Unscrew the top fork fixing to the pitot tube.

2. Start to withdraw the old pitot tube from the top. This may prove difficult, as it is often held firmly
in place by corrosion between the sensor and the housing. It will usually be necessary to use a
mechanical hoist to remove the tube.
3. When certain that the pitot tube has cleared the sea valve, close the valve securely, and
completely remove the tube.

7.2.2 Measurement of transducer depth

The depth of the bore from top to bottom must be gauged to ensure that the new Imcor2 transducer
is fitted with its transducer head flush with the hull. If the head projects outside the hull, it may easily
be damaged when struck by solid objects, or ice.

The depth is conveniently measured using a special Depth Gauge, available from Consilium
Navigation.

Figure 19: Depth Gauge assembly

The depth gauge assembly is shown in figure 19. It consists of the depth gauge part itself, which has
'wings' that can be unfolded by pushing down the gauge-operating rod. (These 'wings' act as a stop
against the outside of the hull.)

The depth gauge must be attached to the transducer connecting tube and the gauge operating rod
fitted through the tube (see figure 19).

1. Insert the assembled gauge into the bore (with the 'wings' folded and the sea valve open) and
push the gauge down as far as possible.
2. Push down the gauge-operating rod to unfold the wings, and pull the whole gauge upwards, as far
as possible, so that the 'wings' locate against the ship bottom.
3. Slide the gauge clamp down onto the top of the sea valve assembly and tighten it securely at this
position.
4. Pull up the gauge-operating rod to fold the wings and remove the gauge assembly.
5. Remove the depth gauge and the operating rod from the transducer connecting tube but leave
the clamp in position.

7.2.3 Transducer fitting

Assemble the transducer in accordance with the instructions given in chapter 7.4 but do not remove
the clamp.

1. Carefully insert the transducer assembly into the sea valve assembly, making sure that the valve is
fully open. On no account use force, this could easily damage the transmitter / receiver
components at the bottom of the transducer.
2. Lower the transducer assemblies until the clamp touches the top of the sea valve assembly.
3. Slide the tube bracket assembly down so that the threaded stem and wing nut locate in the fork of
the valve cover.
4. Rotate the transducer tube so that the flat faces towards starboard. Use a suitable straight guide
bar held against the flat to orientate the transducer as accurately as possible (see figure 18).
5. Tighten the clamp screws and the wing nut.

7.3 Installation in dry dock

Installation in dry dock allows the new external bottom parts to be fitted. The kit includes different
parts suitable for all three types of SAL 24 installations. Depending upon the individual installation,
some modifications may be necessary to the parts in the kit to enable them to fit correctly. These are
described in the following installation instructions.

7.3.1 SAL 24 single bottom

Refer to figures 20 - 24 for the following steps.
1. Remove the old SAL 24 tube. This will usually require the use of a mechanical hoist, especially if
corrosion is present within the bottom parts.
2. Remove and discard the old zinc ring (see figure 20).
3. Grind away the protruding centre sleeve, chamfering inwards slightly to avoid fouling the new zinc
ring when fitted (see figure 21).
4. Ream the middle of the centre sleeve to a diameter greater than 36 mm.
5. Check the fit of the new guide ring in its recess in the housing. If the guide ring is thicker than the
hull it should be ground in accordance with figure 22 so that the bottom face lies flush with the
hull.
6. If the guide ring is thinner than the hull, a packing ring will need to be made in accordance with
figure 23.
7. Place the zinc ring1 and guide ring into their recesses and fasten with four screws (see figure 24).
Note that the screws supplied may require shortening.

Assembly and fitting of the transducer are described in chapter 7.4.

7.3.2 SAL 24 double bottom (old)

Refer to figures 25 - 27 for the following steps.
1. Remove the old SAL 24 sensor. This will usually require the use of a mechanical hoist, especially
if corrosion is present within the bottom parts.
2. Remove and discard the old zinc ring and the centre brass guide tube (see figure 25).
3. Insert the new guide tube into the bore of the assembly, weld in position (see figure 26) and grind
the weld flush.
4. Check that the recess for the zinc ring is clean and flat, grind it flat if necessary.
5. Check the fit of the new guide ring in its recess in the housing, using the four spacers shown in
figure 27. If the guide ring is thicker than the hull it should be ground in accordance with figure 22
so that the bottom face lies flush with the hull.
6. If the guide ring is thinner than the hull, a packing ring will need to be made in accordance with
figure 23.
7. Assemble the packing spacers, zinc ring2 and guide ring into their recesses and fasten with four
screws (see figure 27). Note that the screws may require shortening.

7.3.3 SAL 24 double bottom (new)

Refer to figures 28 and 29 for the following steps.
1. Remove the old SAL 24 sensor. This will usually require the use of a mechanical hoist if corrosion
is present within the bottom parts.
2. Remove and discard the old zinc ring and guide tube (see figure 28), together with the eight fixing
screws.
3. Check the fit of the new guide ring in its recess in the housing. If necessary, grind it in accordance
with the instructions given for the SAL 24 single bottom conversion (figure 22)
4. If the guide ring is thinner than the hull, a packing ring will need to be made in accordance with
figure 23.
5. Assemble the zinc ring3 and guide ring into their recesses and fasten with four screws (see figure

Assembly and fitting of the transducer are described in chapter 7.4.

7.4 Transducer fitting

7.4.1 Transducer assembly

1. Fit the small O ring into the recess at the top of the transducer. Pass the cable through the
transducer connecting tube, making sure the tube is the correct way round (see figure 30).
2. Attach the transducer to the connecting tube with four MC6S4 × 10 screws; the alignment peg
ensures that it can only fit one way round.
3. Screw the cable gland and O ring into the connecting tube and tighten the gland around the cable.
4. Slide the tube bracket assembly onto the transducer assembly and slightly tighten the clamp
screws.

7.4.2 Transducer installation

8 Cabling
The TRU is delivered with a 30 metre cable mounted. It is a four-wire cable with inner shielding.
This cable connects the TRU to the ELC. The cable must have no joints via any junction box of any
kind, but be connected directly from the transducer to the ELC. Do not under any circumstances
cut the cable!

To make sure that the R1 works well the cable should not be fastened close to other high voltage
cables (440 VAC or more). If the cable is too long roll up the extra metres outside the ELC box. Do
not store any extra cable inside the ELC. The extra metres inside will act as an antenna and may
affect the electronics.

2. Mechanical dimensions
The ELC is designed for surface bulkhead mounting and has a gland plate at the bottom for cable
entry. The ELC case is IP 65-enclosure type suitable for indoor locations such as engine rooms,
ballast pump rooms and similar rooms below the load line. However, in any case the ELC should
never be installed below floor plates. It should never be installed in any locations permanently
exposed to water!
The overall dimensions and mounting details for the ELC are given in the figure below.

Figure 2 R1 Dimensions

3. Selecting location
An obvious requirement for selecting a good location of the ELC is the standard 30 m. cable to the
transducer, as mentioned above. Other criteria for the chosen location are:
• The ELC must be easily accessible for transducer replacement, log calibration or other service.
• The location should be reasonably sheltered and should offer a stable temperature that must never
be outside the range 0 - 40°C.
• The location must not expose the ELC for excessive vibration levels.
• The location should be far from electrical installations giving excessive electric and/or magnetic
fields, such as powerful electrical motors for ventilation, bowthrusters etc.
• There must be a reasonably good way of laying the 30 m. cable to the transducer in such a way
that enables transducer replacement.
• The drawing above defines the mechanical dimensions. There must be a flat surface for mounting
and it must also be possible to fit the four bolts. Note also that there must be enough room (350
mm. free space in front of the unit) for opening the doors to access the electronics inside and that
there is room for cables below the cabinet.

4. Installation procedure
4.1. Introduction
Depending on how the order was placed, a ship's specific wiring diagram may be delivered with this
manual. If not, a typical wiring diagram is included.
In general, it is sufficient to fulfil some simple rules for good electrical connections within the system.
• The ELC shall be firmly grounded to the ship's structure. An extremely solid connection is to be
made between the metal structure of the hull and the grounding screw on the outside of the case.
The cable area of this connection shall be at least 10 mm2, preferably using copper braid.
• In all cases the cable screens must be connected ONLY to the ground stud in the electronics unit.
The screens must NOT be connected at the display units or other users.
• All wires shall be electrically shielded and all signal wiring to the connectors shall be twisted pairs.
The mains supply will require a separate cable, which need not be screened.
• For IEC 1162-1 / NMEA, analogue or pulse signals, a cross-section of 0.25 mm2 is electrically
sufficient, although dimensions 0.75 mm2 to 1.5 mm2 normal ships cable are recommended.

4.2. Mechanical installation

1. Loosen the four screws of the chassis. Also disconnect the earth link at the chassis end. Remove
the complete chassis by lifting it slightly upwards and out of the case.
2. The case mounting holes should be filled with fibre sealing to maintain water tightness.
3. Mount the case to the bulkhead using M6 screws or equal.
4. Replace the chassis in the case, reconnect the earth link and tighten the four chassis mounting
screws.

Figure 3 R1 ELC

The electrical connections to the ELC is fairly simple in a normal installation, since the number of
cables to be connected in a standard installation is small, see table 1.
1. Start with installing the transducer cable. The transducer cable is marked with cable numbers at
the end. Each cable number corresponds to the same terminal number. Never shorten the
transducer cable since this will seriously impair performance of the log system.
2. Next step is power connection. Start with making sure that available power is within system limits
stated. Connect available power to the concerned terminals 37,39 and 40 for 230 VAC. If the R1
supplied is built for 115 VAC the same terminals may also be used for this voltage, see chapter on
Power Supply.
3. Finally connect the indicators or the extension box to the NMEA output.

5. Display units
Different display units can be connected to the electronics unit, e.g.:
• Digital Speed and Distance Display SD1-X
• Digital Speed Display SD2-X
• R1 Main Digital Speed Indicator SD3
• Analogue Speed Indicator SIA2-7, SIA1-3
• Digital Speed and Distance Display DD1-1
The display units present in the current installation are described in detail in other sections. A
maximum of ten SD-indicators can be connected to the serial RS485 output (the NMEA output). It
is also possible to power up to three SD-indicators straight from the R1 ELC.

8. Downloading of new software

The R1 ELC is delivered with the software installed in a flash memory. If, however, an update of
software would become necessary, this chapter explains how to do it.

If the downloaded software has been corrupted, the R1 will also prompt for new download by
writing "BOOT FAIL". The SAL R1 will then reset at regular intervals. The first message is:
SALR1 BOOTLOADER
Rev. 701822B0
followed by
SALR1 BOOTLOADER
BOOT SUCCESS
when the software has correct checksum, or
SALR1 BOOTLOADER
BOOT FAIL
when the software has a faulty checksum.

Flashing new software must be made using a special cable. The connectors 1, 4 and 5 on the R1 9-
pole D-sub should be connected to the connectors 2, 3 and 5 on the PC COM-port 9-pole D-sub:

2 2
7 7
3 3
8 TXD 8

9 9
5 GND 5

Figure 7 Special cable for communicating with R1

Flashing is performed with a MS-DOS based PC-based program delivered with the software
update. It may be necessary to try a few times to connect the PC to the R1. During programming,
which takes about 15 minutes, the serial channel will be occupied for flashing and other units
connected to the log may behave unexpectedly as special data will be sent out. After the update is
finished, the log will automatically reset. The typical command line for an update can be:
c:> flash38k –b38400 –d701823E4.ihx -u
Writing only flash38k shows an argument description for the program.

SAL R1 ELC installation 701850AD.doc

The PC program starts by establishing connection to the R1. It then reads the old code (if it is
available). The R1 then erases the flash, and finally the new software will be downloaded into the R1.
If an error occurs during download, the R1 will write a message on the LCD indicating that it awaits
the sequence to be restarted.

9. Optional equipment
9.1. R1P
If the R1 has an extra serial-to-pulse converter board, R1P, mounted (inside the ELC) data can be
output as pulses (four outputs 200 p/NM, one output 20 000 p/NM) and analogue voltage (one
output 0,1 V/knots and one forward/astern indicator ± 5 V). When an R1P is mounted the R1
becomes fully compatible with a SAL-Imcor2 and can replace the Imcor2 in any installation. See
section on R1P for details.

9.2. Extension box

There are three different possibilities for extension box in an R1 system: Log Processing Unit (LPU),
Log Distribution Unit (LDU) and Log Extension Box (LEB 1-5). Their common mission is to
distribute data and power to a larger number of indicators. If one of them is present in the current
installation the relevant manual is included in section on extension unit.

10. Power Supply

A standard SAL-R1 is adapted to 230 VAC power supplies. However, qualified service engineers
can adapt the R1 for 115 VAC power supply on demand.
Remove mains supply. Remove the front covers plates and change the connections of the
transformer. The different connections can be found in the figures below. NOTE: if a unit is changed
to 115 VAC power supplies, this have to be informed to Consilium Navigation AB.

1. Background
The new SD1 display is intended as a versatile multi-purpose digital display. By changing the
front panel and re-programming the unit, different configurations of displayed information is
available. These versions are defined here.

2. Function, general
All instrument versions will decode all defined messages and display all possible information if
available. This means that a complex instrument like version 6 will connect to a simple water-
track log like SAL-Imcor or SAL R1 and display water-track speed only.

2.1 Lamp test

By pressing both "DIM" keys simultaneously during operation, the instrument will light all
segments and indicators. This function is available in all operational modes.

2.2 "RESET TRIP" key

This key is used to reset the local trip distance counter. To prevent accidental operation, it
must be pressed for two seconds to operate.

2.3 Serial/Pulse data

Some of the SD1 versions will work with both pulse and NMEA data. There are no settings to
be done to switch the instrument between the two versions. When an instrument receives
NMEA data for the first time, it will enter the NMEA mode and discard any pulse input. The
reverse situation is not available; the instrument will only enter pulse mode when serial data
has not been received. To reset this condition, mode "254" must be programmed. See
section 6 for this.

If SD1 indicators are programmed to the ”3X” series of modes, the pulse/status inputs will be
interpreted by the indicator as remote control inputs for the push buttons.

2.4 Invalid/unavailable information

Depending on the NMEA formats, invalid data can be indicated by certain status characters or
by missing (NULL) data fields. In this case the corresponding display field will indicate "---". In
some cases it will also force the indicator to another display mode.

2.5 Incorrect/missing NMEA messages

If syntactically correct NMEA messages are not received within an approximate time limit of
15 seconds, the indicators will display "Err" in the upper display field.

This means that if for instance a speed indicator receives properly formatted depth data only
(for instance $VDDPT...), it will not enter the "Err" mode but keep on decoding and treat all
input data as invalid.

2.6 Remote DIM messages

All SD1 versions using D0 program version or later will respond to the $PSALR remote DIM
message. This means that all SD1 displays connected to the NMEA output of a SAL device
having the remote DIM facility will increment or decrement their light intensity as controlled by
this device (such as, for instance SD2-5 or SD2-6).

3 (19)
çConsilium Serial Digital Displays SD1 Art No. 701034L1

2.7 Total Distance

The function total distance has changed (software 701059F0 and above) to support remote
operation. The total distance counter is available only in WT (water track) mode. For
indicators with Bottom track the total display will show "------" for unavailable information. The
total distance is remotely controlled with a serial message (distance through water $--VLW).
Local accumulation will still be used if no serial distance message is available.

water.

The indicator also operates from pulse/status inputs. In this case, however, the BT/WT key is
inactive, since choice between WT/BT status is defined by the status input.

Operation
The BT/WT key switches the instrument between BT and WT indication, which is shown by
the LED beside the speed display. The instrument will indicate "---" if asked to show data not
available. However, it will automatically switch to WT status if BT tracking is lost. In this case,
automatic switch over to BT will take place again when BT is valid.

The Trip/Total key will toggle the lower display between the two separate distance counters
for trip and total distance accumulation (trip: WT or BT; total: WT only with $--VLW). $--VLW
messages are decoded. This will set the total distance counter to the value contained in the
message. The local trip distance counter will NOT be affected by this message, it will
continue to integrate distance from displayed speed.

The Reset Trip key will reset the trip distance counter. It must be held for at least 2 seconds
to perform this function to avoid accidental resetting. Note! This 2 second safety time-out can
be ignored if the instrument is programmed to version #21 instead of the standard #1.

However, this indicator version is intended also for pulse operation and it will indicate and
display WT or BT speed and distance from 20 kp/NM SAL pulse outputs as defined by
connected status signals.

It is intended primarily for the SAL Imcor 2 WT logs with NMEA or pulse operation and for SAL
840 or SAL 860 WT/BT logs if operated with pulse input. For SAL 840/860 logs with NMEA
outputs, the SD1-1 is a better choice, since this gives local choice of WT or BT operation.

Operation
If operated on pulse input, the BT/WT status input will control indication of what is being
displayed. If operated on NMEA input, the indicator will display BT longitudinal speed
whenever possible, else it will switch to WT indication.

The Trip/Total key will toggle the lower display between the two separate distance counters
for trip and total distance accumulation. In both cases, the distance counters will accumulate
the displayed speed (trip: WT or BT; total: WT only with $--VLW). $--VLW messages are
decoded. This will set the total distance counter to the value contained in the message. The
local trip distance counter will NOT be affected by this message, it will continue to integrate
distance from displayed speed.

Operation
"Long/Trans/Res" button will switch between three modes:

- "Long" will show longitudinal speed and distance if available. It will indicate by lighting one of
the two arrow indicators showing ahead or astern.

- "Trans" will show transversal speed and distance if available. It will indicate by lighting one of
the two arrow indicators showing port or starboard direction.

- "Res" will calculate and show resulting speed on the upper display and, depending on the
mode of the lower display, speed vector direction referenced to the bow direction or the
resulting distance on the lower. The direction will be displayed in degrees 000° to 360°.
Lighting two arrow indicators, displaying the quadrant in which the speed vector is found will
indicate this mode. Example: The ship moves with 20 Kt. with the speed vector 10° on the
port bow. In the "Res" mode, the instrument will display 20.0 on the upper display and 350° or
resulting trips or total distance on the lower.

"BT/WT " button will switch between two track modes:

- "BT" will show bottom track speed and distance if available,
- "WT" will show water track speed and distance if available.

"Trip/Total/Dir" key will switch between trip distance, total distance if in "Long" or "Trans"
modes and between trip distance (WT or BT), total distance (WT only with $--VLW), speed
vector direction if in "Res" mode on the lower display. $--VLW messages are decoded. This
will set the total distance counter to the value contained in the message. The local trip
distance counter will NOT be affected by this message, it will continue to integrate distance
from displayed speed.

6.2.1 Manual Programming

The programming mode is entered after completed self-test (with an un-programmed
instrument) or if both "DIM" keys are pressed during power-up. The version number is
displayed for about 1 second and the "DIM" keys are then used to increment/decrement the
version number in the range 000 - 255. When a chosen number is displayed, the
programming is verified by pressing key #2.

The following modes are implemented:

6.2.2 Remote programming and testing

Entering special test and programming proprietary messages via the NMEA input can do this.

6.3 Testing
If the instrument is powered without being programmed (or programmed to version #0), a test
sequence is performed.

1. All segments are tested with a "running light"

2. Pressing them, one at a time, can test keys-1 - 5. The corresponding key number is
simultaneously indicated on the upper display.

3. Applying input voltages can test all inputs. The digits in the second row will indicate this.
Digit #1 will reflect reception of 4800-baud serial data ASCII character "T" by indicating "g"
(good) instead of "b" (bad). Digits #2 - #4 will reflect input voltage level of the three inputs, 0 =
low, 1 = high.

4. The instrument waits for a stroke on key #6, display this digit and starts counting 60
seconds to check internal timing. This counting can be interrupted by pressing key #5.

The instrument then enters programming (= 000) mode.

çConsilium Serial Digital Displays SD1 Art No. 701034L1

7. Accessories
The indicator family SD1 can be equipped with a number of accessories, including a sealing
frame for watertight installations, a bulkhead mounting box for situations where the display
cannot be mounted in panel and an AC power supply for 115/230 V AC powering.

7.1 Sealing frame

Note that the indicator itself is watertight when mounted into flat surface panel.

14 (19)
çConsilium Serial Digital Displays SD1 Art No. 701034L1

7.2 AC power supply SDP

The AC power supply is designed for mounting with the four screws holding the back cover of
the indicator. As an alternative, where space is very limited, the power supply unit can be
mounted beside the indicator.

The power supply is designed to power up to two SD1/SD2 indicators in parallel if operated
from 230 V AC supplies. If connected to 115 V, only one indicator can be powered.

7.2.1 Installation
To install directly on SD indicator, remove the four screws holding the back cover and use
these screws to hold both the SDP power supply and the back cover.

Connect the black wire to the negative DC supply input of the indicator and the red wire to the
positive.

Connect AC 115/230 V AC as shown on SDP.

7.3 Bulkhead mounting box

This can be used to mount the indicator on any flat surface. The cable intakes are supplied
with cable glands for IP65 protection for cable diameters in the range 9 - 20 mm. If necessary,
this box can be combined with the sealing frame where it is desirable to achieve a watertight
installation.

Electrical Connections

As could be seen from drawing above, SDR terminals 3 - 6 and 9 - 10 should be connected to
the corresponding terminal numbers of the SD1 indicator. Unused terminals of the SDR are
not connected and can be used for internal wiring between ship’s system and SDR/SD1
combination.

Operation
The pushbuttons of the SDR remote control duplicate the pushbuttons of the corresponding
SD1 indicator exactly.

It should be noted, however, that only single key operations are possible and in addition to this
the ”Test” function is available by pressing the two DIM keys at the same time.

NMEA universal display SD2, Technical Description

1. Background
The SD2 display is intended as a versatile successor to the DD-1-1. It is very similar in
function with the SD1, which is described in document 701034.

The different display versions of the SD2 series are utilised using the same main indicator
body, 701152. Two different versions have been produced, 701152 and 701152B or later. The
first one uses inter-illuminated keys, while the later version uses one indicator LED for each
key. Thus, the two versions uses different front panel foils and different front panel plates.

All other performance is similar and the earlier versions can execute the same software.

This description is valid for program version from C0.

Generally, all instruments will enter all requested modes if the information is available in the
data format received even if part of the required information is momentarily missing. The
missing information will then be indicated by displays showing "---" or applicable, not by
blanked displays or "000". However, the instrument will not enter a requested mode if the
received data format suggests that the needed information is permanently missing,

2.1 Lamp test

By pressing both "DIM" keys simultaneously during operation, the instrument will light all
segments and indicators. This function is available in all operational modes.

2.2 Invalid/unavailable information

2.3 Incorrect/missing NMEA messages

If syntactically correct NMEA messages are not received within an approximate time limit of 15
seconds, the indicators will display "Err" in the upper display field.

2.4 Remote DIM message

All SD2 versions have the feature of receiving and processing the remote $PSALR message.
The versions SD2-5 and SD2-6 have the possibility to transmit such messages using the
remote DIM keys. When this is done the transmitting SD2-5 or SD2-6 changes its own light
level at the same time as the other indicators connected to its output.

2.5 200 p/NM speed output pulses

All SD2 versions measuring and displaying speed (SD2-1, SD2-2, SD2-4, SD2-5 and SD2-6)
transmit industry-standard 200 pulses/nautical miles on their status/relay outputs in the
following way:

Connection #5 and #7: WT longitudinal. If WT speed is unavailable, BT speed is output

instead.

Connection #6 and #8: BT longitudinal (For a single axis log such as SAL 840) or BT resulting
(For a dual axis log such as SAL 860/865). If BT is invalid/out of range, WT speed will be
output instead.

Relay on terminal #9-10: Operates in parallel wit terminals #5 - 8 depending on the setting of
internal jumper:

This version is designed exclusively for Docking log applications and displays transversal BT
speed of bow and stern and longitudinal BT speed. The instrument will switch to WT when no
BT speed is available. If no transversal WT speeds area available (such as with the SAL 860
log) the transversal indicators only shows "---" to indicate that the transversal speed
information is not available. The WT and BT indicators will be lit to indicate mode.

The "WT" and "BT" keys can be used to manually force the display to showing WT or BT
speeds.

The "knots" and "m/s" buttons can be used to display either and the corresponding key will be
lit to indicate which.

This instrument will decode the $PSALL proprietary NMEA message and the $PCVDL non-
standard message. The instrument shall be used with SAL 860 Docking log system, where
integration of log and gyro information is done in the Log Processing Unit.

This version will decode $??DPT, $??DRU and non-standard $PC--- messages as defined in
701164.

The True/Meas key will switch between indication of True (Measured depth + entered draught
value) and measured depth. The indicators to the right of the depth display will indicate what is
being displayed.

The Shall set key will toggle the instrument between normal operation mode and Shallow set
mode, which is indicated by illumination of this key. In the latter mode, the DIM keys can be
used to decrement or increment the Shallow alarm level. The entered Shallow value is always
the value corresponding to the "True" depth setting and will then be affected by the chosen
draught offset value in the way that the "True" mode will be entered whenever the Shallow or
Depth set modes are entered. Example: If the Shallow alarm is set to 20 m, the shallow alarm
display will show "20". If the indicator is switched to "Meas" mode, and a draught offset of 10
m is programmed, the shallow alarm level will display "10", since this is the correct alarm level
chosen by the operator.

The Depth set key operates the Depth alarm as described above.

The Draught set key toggles the instrument between normal operation and Draught set
mode. In this mode, the upper display shows the draught set value, which can be altered by
the DIM keys. The mode is indicated by the Meas and True indicators both being unlit and the
Draught set key being lit.

The four logic outputs of the instrument are used in the following way:

or if depth is invalid.
7 Goes high if Shallow or Depth alarm is activated or if NMEA
transmission is lost. This alarm can be reset.
8 Goes high as above but cannot be reset manually.

3.3.1 Output alarm relay setting

The relay on terminals 11 and 12 can be connected to work in parallel with any of the above
outputs with a jumper inside the indicator. In normal operation, the relay contacts are closed,
while an alarm condition opens relay contacts!

3.3.2 Buzzer operation

The indicator has a built-in buzzer that will give an audible alarm if the depth or shallow alarms
are activated. It will sound as long as the alarm condition is valid or it can be re-set by pushing
one of the DIM keys.

3.3.3 Disabling buzzer

By programming this indicator to version number 13, the audible alarm buzzer can be
disabled completely. This is done in the following way:

1. Disconnect power.

2. Re-connect power again while pressing the two DIM keys.

3. Release the DIM keys and use them to alter the figure displayed in the upper display
window until it reads 13.

4. Confirm by pressing the Shall set key and the indicator will restart in mode 13.

This instrument is used to set two different WT calibration factors and to change rapidly
between these two and the normal log calibration value.

The display windows show the Uncalibrated speed (top), which is the speed as fed directly
from the log (utilising the set calibration value of the log). The calibrated speed (middle) is the
output from this device and the calibration factor (bottom) that is used to for multiplying the
input speed to obtain the corrected speed value.

Operation
The three keys marked ”1”, ”2” and ”3” are used to enter the three different calibration values.

In mode ”1”, the unit is inactive and the output is directly fed from the input. This means that
the calibration value is used directly as input from the log. By connecting a SDE relay board to
the indicator it is possible to retain a high redundancy of the system by actually physically by-
passing the indicator in mode 1 and in power failure condition.

In modes ”2” and ”3”, the calibration factor is used to multiply each reading from the log.

The ”Set” key activates the Set function in modes 2 and 3. This Set function is indicated by
the LED over the ”Set” key and the ”DIM” keys can be used to alter the corresponding
calibration value.

When the set function is terminated by pressing the Set key again, the value displayed in the
bottom display window is stored and will be used.

This version is used as a simulator, primarily in SAL 860/865 installations. It simulates NMEA
messages, but also produces pulse and status inputs to emulate the previous SAL STU

simulator and provide input to non-NMEA SAL 860/865 logs. The instrument is available in the
following variants:
Program version Article number Serial messages
#9 701161 old non-standard PCVVD messages
#10 701322 VDVBW and VDDPT
#17 701171 For SAL T2: PSALD, VDVBW and VDDPT

Generally, NMEA operation is recommended.

15 (31)
çConsilium Serial Digital Displays SD2 Art No. 701592Eb

Pulse operation
The simulator also produces standard 20.000/NM SAL pulses on its 4 outputs in the following
way:

Term# Signal name Term# in SAL 860/865

5: Transversal BT speed 36
6 Longitudinal BT speed 33
7 S/P BT status 35
8 STU on control signal 32
(13 STU2 ground signal 31)

Note that there must be a ground path between the negative power input terminal of the STU2
and terminal 31 of the log.

In pulse operation, BTT and BTL pulses and S/P status is input to the SAL 860 and these data
are used by the log instead of internally generated pulses. No input for depth is used in this
manner, nor input for WT speed. WT speed can be simulated by thumbwheel settings of the
WT unit directly.

Operation
WT: Enters WT display mode, which is indicated by the WT key LED being lit. Only the
entered WT speed is indicated, other digits are blanked.

BT: Enters BT display mode in the same way as above. All three fields are displayed, showing
the currently stored BT speeds and depth.

Set: Enters Set mode and chooses display field to operate on. Set mode is indicated by
illumination of the Set key LED. The set mode key toggles between two or four states,
depending on the BT/WT mode: Set mode off, Depth set (BT only), Longitudinal speed set
(BT/WT) and Transversal speed set (BT only). The chosen active display is the only one
shown and the DIM keys are used to decrement/increment the setting.

Sim on: Switches simulation on, indicated by this key LED being lit. In this state, the following
functions are active:
• The relay contact is closed.
• NMEA data are transmitted.
• Pulse outputs are active.
• NMEA input is ignored.

When simulation is switched off (with the Sim on key), the following applies:
• The relay is open.
• Any messages received on the NMEA input are echoed to the NMEA output without
decoding.
• The pulse output is inactive.

simulator is inactive it will work as an NMEA to pulse interface and convert incoming NMEA
and generate 20’000 pulses resulting speed on output terminal 6.

The pulse output can be changed between BT / WT. If BT is chosen and no valid BT NMEA is
available it will automatically switch to WT.

When simulation is inactive the SET key will be disabled to prevent any disturbance of the

R1P 701859B0.doc

1. Introduction
The R1P is an optional converter board that is mounted in the SAL R1 ELC either when the R1 is
installed to retrofit an old SAL-Imcor2 speedlog or when the R1 is part of a larger SAL 860 system.

When an R1P is mounted in a stand-alone SAL R1 this combination becomes totally compatible with a
SAL-Imcor2 and can replace the Imcor2 in any installation. This is achieved by having the R1P to
interpret the serial data from R1. Data is output as pulses (four outputs 200 p/NM, one output
20 000 p/NM) and analogue voltage (one output 0.1 V/knots). There are also two status signals: One
LogFail relay and one Forward/Astern indicator ± 5 V. As with the Imcor2, the R1 can power two
DD1 indicators using 48 VAC.

When an R1-R1P combination is part of a larger log system it receives pulses from the bottomtrack part
in the SAL 860 and converts them to NMEA messages.

2. Installation
2.1. Stand alone R1-R1P in SAL-Imcor2 retrofit
Normally the R1P is already installed in the R1 ELC when delivered. If, however, the R1P is delivered
separately it is easily attached to the contacts J5 and J6 on the lower side of the R1 motherboard.
Fasten the R1P with the screws and spacers for the front plate and finally fasten the front plate.

R1P 701859B0.doc

For having the R1 as relative speed input to SAL 860 one link is necessary inside the 860 ELC: Make a
link between plinth no 30 and 31 (0 V SAL59 and 0 VDC).

3. Hardware resources and utilisation

The R1P has four pulse-relays and one toggling relay. These relays can take a load of 200 mA and a
maximum voltage of 30 V. No inductive or capacitive loads are accepted.

The analogue voltage can output a maximum of ±5 mA. Please note that astern speeds yields negative
voltage on this output.

There are also eight optocouplers inputs for communication with SAL 860.

4. Types of messages
Two types of input messages are recognised. The dual Doppler velocities messages,
which are decoded for watertrack speed and the ‘$PSALG,....’ message which disables the serial
channel reception the specified number of seconds.
Ex:
$VDVBW,10.0,,A,14.0,2.0,A,,V,,V*55\r\n
$PSALG,10*64\r\n

If a SAL 860 is connected, dual Doppler velocity and depth messages are transmitted.
Ex:
$VDVBW,10.0,,A,14.0,2.0,A,,V,,V*55\r\n
$VDDPT,123.0,,,*50\r\n

Simulated dual Doppler message is transmitted with or without transversal speed depending on the DIP
switch setting.
Ex:
$VDVBW,15.0,,A,14.0,0.8,A,,V,,V*76\r\n
$VDVBW,15.0,,A,14.0,,A,,V,,V*50\r\n

5. Program structure
The program has two main tasks. One is to receive watertrack speed from SAL R1 and generate
pulses. The other task is to receive pulses from SAL 860 and generate NMEA messages once every
second.

6. Speed range
At speeds faster than 49.9 knots forward or astern, the speed to the relays and the analogue output will
be set to zero. However, all valid speeds will be output on the serial channel - for highspeed vessels this
includes speed greater than 50 knots.

R1P 701859B0.doc

7. DIP switch settings

An 8-pole DIP switch - SW1 - is located on the R1P board. It is used to identify the system to the
software. The DIP switch positions should not be changed during normal operation! Default values are
shown in highlighted letters:

SW1.1
Off Normal
On Internal simulation. Depending on setting of SW1.2 and
SW1.3 messages for SAL R1, SAL 840 or SAL 860 will be
generated.

SW1.2 SW1.3
Off Off Stand-alone SAL R1
On Off R1 board in SAL 860 log system
On On R1 board in SAL 840 log system

SW1.4
Off Normal
On CPU reset. This setting has priority over all other settings.

SW1.5
Off Normal
On Production test

SW1.6 SW1.7
Off Off Analogue output is positive for forward and negative for
astern speeds
On Off Analogue output is positive for both forward and for astern
speeds (Imcor mode)
On/Off On Analogue output is positive for both forward and zero for
astern speeds

SW1.8
Off Log fail is deenergised for unvalid water track speed
and power fail
On Log fail is deenergised for power fail only

R1P 701859B0.doc

7.1. Normal mode

Serial data NMEA messages are received. Analogue output 0.1 V/knot, 200 p/NM and 20 000 p/NM
are generated. SAL 860 and SAL 840 modes are disabled.

7.2. SAL 840 mode

Incoming pulses at P3.2 generate longitudinal bottomtrack speed. Transversal bottomtrack speed is not
shown. Incoming pulses at P3.1 generate depth messages.

7.3. SAL 860 mode

Incoming pulses at P3.2 and P3.3 generate longitudinal bottomtrack speed and transversal bottomtrack
speed. Incoming pulses at P3.1 generate depth messages.

7.4. Reset
With the DIP switch SW1.4 in position ON the R1P will constantly be reset.

8. Test facilities
8.1. Simulation
In the simulation mode the serial channel reception is disabled and internal messages are generated.

For the stand-alone R1-R1P no simulated messages will be transmitted.

For the R1-R1P in a SAL 860 system the following message is transmitted:
$VDVBW,15.0,,A,14.0,0.8,A,,V,,V*76\r\n

For the R1-R1P in a SAL 840 system the following message is transmitted:
$VDVBW,15.0,,A,14.0,,A,,V,,V*50\r\n

8.2. Production test

There is an automatic production test procedure implemented in R1P. To test the hardware using this
procedure the inputs of the R1P are used. Cables should be connected according to the following:

8.2.1. Optocouplers and ±5 V outputs

Connect J3.1 to P3.1
Connect J3.2 to P3.2
Connect J3.3 to P3.3
Connect P3.9 and P3.10 to P4.3

8.2.2. Optocouplers and relay outputs

Connect J1.3, J2.2, J4.2, J5.1 and J5.3 to P4.1
Connect J2.1 to P3.4

1. Background
The purpose of this document is to define the various messages that are used
by the SAL logs and interface units. Therefore, it is intended to be used as a
sub-document to various specifications and technical descriptions.

1.1. References
• IEC 61162-1:2000(E) standard.

• NMEA 0183 v 2.30 standard.

2. Serial Data message definitions

Three classes of messages are described in this document: industry-standard
IEC 61162-1/NMEA messages, special proprietary Consilium messages and
early version NMEA messages. The used definition follows the NMEA
standard with the addition of variable length integer field to allow easier
implementation in micro-controller circuits. Note that fields may be empty,
i.e. without characters and followed by the next comma separator.
Field Type Symbol Definition
Status A Single character field: A=data valid, V=data invalid.
Variable x.x Normal definition of a floating format variable. The integer version
length floating separated into a new definition.
Variable i. Consilium extension with variable length field. Normal definition of a short
length integer integer format variable.
Fixed hex hh- Hex field with same number of hexadecimal characters as specified. MSB
to the left.
Variable text c—c Valid character field of variable length.
Fixed alpha aa- Upper & lower case alpha characters [0..9, Aa, Bb, Cc, Dd, Ee, Ff].
Fixed number xx- Fixed length integer value.
Fixed text cc- fixed length valid characters.

2.1. Standard IEC 61162-1 2 nd ed/NMEA 0183 version 2.30

messages
The intention of Consilium Navigation is to implement the standard messages
as defined in the IEC 61162-1, 2nd edition. This corresponds to the NMEA
0183 version 2.30. All outputs will, whenever possible, refer only to
messages defined in these documents.
The checksum is mandatory and calculated as the EXCLUSIVE OR of the
ASCII representation for all characters between the $ and * in the message.
Typical messages are shown below.

2.2. Proprietary Consilium Messages

Consilium Navigation has been allocated the proprietary mnemonic "SAL" by
NMEA. This means that any message starting with "$PSAL..." emanates
from Consilium Navigation equipment and that any letters following can be
chosen by Consilium Navigation. However, to comply with standard NMEA
messages, all these messages uses a five-character combination $PSAL-
before the first delimiter.

6 (23)
çConsilium IEC 61162-1/NMEA 0183 Message definitions Art No. 701164J3

These proprietary messages are mainly used for internal programming,

trouble-shooting etc and are only used in normal operation where good
alternatives are missing completely.

2.2.1. 2-wire bus messages

The use of 2-wire bus messages is an attempt to use the powerful RS-485
standard in a more efficient bi-directional way than as defined by the IEC
61162-1/NMEA 0183 standard. It is only used for some specific
installations.
The following method is used for bus arbitration. A device may put a
message on the bus provided that the bus has been in the idle state for at least
50 ms. If a message is being transmitted it must wait 50 ms and than an
additional number of 2 milliseconds corresponding to the identity of the
device (= the ”Y” two digit originator code below) after the finalisation before
entering the bus. During all this time the bus must be stable in the idle state.
Upon completion of the message sent, it must check the bus to idle in at least
10 bit times. Otherwise the message must be regarded as never sent and the
transmit procedure must be re-started.
Since all messages results in an ACK response (except for global ”00”
messages) and since the bus arbitration procedure is somewhat simple and
slow, the device must wait for an ACK at lest 5 seconds before trying to re-
transmit.
Syntax:
$PSALB,X,Y,Z,.......*HH,

X = Message destination according to list below

Y = Message originator according to list below

00 = All listeners (destination field only)

01 = SAL R1 as primary log
02 = SAL T2 as primary log
03 = SAL R1 as secondary log
04 = SAL T2 as secondary log
05 = SAL SD3-1 as R1 main indicator and remote control device
06 = SAL LDU as main signal distributor
07 = SAL NSC
08 SAL PSCG

Z = AAA (Three letters). This indicates that the following information is a

standard NMEA message, for instance ”VBW” means that the rest of the
message looks like a standard $??VBW message.

000 (Three digits). This indicates that the following information is a standard
SAL 2-wire bus message, intended for programming, calibration, setup etc.

These are defined below:

000 General communication reset/initialise. Resets all pending lost ACKs

etc. no data field behind this.

001 NULL message. Used to signal ”I am here, are You there”, which is
accomplished by the ACK return answer. No data field behind this or one
data field, which should contain a string defining identity and serial number of
the sender. On ACK the answer back - device appends it’s own identity.

Example:

$PSSALB,05,01,001,701800A 326-013*HH

Means ”Hello SD3-1 my main instrument, I am a 701800A (which is U/N

for SAL R1) and my serial number is 326-013”.

The SD3-1 receives this properly and answers:

$PSALb,01,05,001,701589A 678-123*HH

Which means: ”Hello SAL R1, your message type 001 was properly
received and I am 701589A (which is U/N for SD3-1) and my serial number
is 678-123”

Note the use of the ”space” character as delimiter between U/N and S/N.

002 MENU control. Reroute menu control to operate from message

instead.

$PSALB,X,Y,002,S,[T]*HH, where

S = Menu control button, ”M” = MENU, ”E” = ENTER, ”+” = ”+ key”, ”-”
= ”- key”, ”R” = MENU&ENTER (return) ”D” = MENU&MINUS
(decrease) and ”?” = no action.

T = Contains the data field expected to be input from the operator before the
ENTER key is hit to store the value.

The corresponding ACK message is a little bit more complicated, since the
return message defines the menu appearance. The number of ACKs returned

8 (23)
çConsilium IEC 61162-1/NMEA 0183 Message definitions Art No. 701164J3

is decided by the ACK sender. This is done to enable continuous updates of

a remote LCD. The PSALb is defined by:

$PSALb,X,Y,002,string,pos,number,status*HH

where:

string = all characters of the display window

pos = a number containing the position in the string where the field requiring
input starts (cursor position). The first character is number 1. ”0” is used to
indicate that there is no input field in that menu.

number = the number of digits/characters in the input field.

number = ”0” indicates that the input field is to be updated by the ACK
sender.

status = the status of the previous action. ”S” = the data of the previous
message containing the ”ENTER” command was stored successfully.
Otherwise, any other character or a NULL character is used.

Note that the device used as a remote control device will use the ”+” and ”-”
keys locally to modify the input field as long as the previous response from
the controlled device contained a valid definition of the input field i.e. number
≠ ”0”.

2.2.1.1. 2-wire bus ACK message

$PSALb,X,Y,Z*HH,

X = Message destination according to list. This is the ”return” address.

Y = Message originator according to list. This is the ACK originator.
Z = Message type that was properly received.

Example:

A SD3-1 is connected to a SAL R1 log and transmits menu control data for
calibration, type 002:

$PSALB,01,05,002,E,120*HH

The SAL R1 receives this message and acknowledges by sending:

$PSALb,05,01,002,(calibration data stored)*HH

Which means the menu setting 120 was entered.

and they are not generated by any equipment shipped after 1992. The
number of logs generating these messages is very small. If any problems
arises decoding these messages, these shall be converted using SW releases
that converts to the standard "$VD...." messages.

The status character handling is complex due to the fact that exact emulation
of existing WT/BT/AUTO functions of the SAL log systems was requested.

Status interpretation:

W Water track, value OK and may be used.
F Water track forced, AUTO/WATER input in WATER
position. This is implemented to accomplish compatibility with
earlier installations.

2.3.3. Atlas Marine messages based on early versions of NMEA 0183.

These message definitions are included here because they are widely used.
They are in some cases decoded by products from Consilium Navigation in
the formats described here. However, since they are generated by other
manufacturers equipment, Consilium Navigation can take no responsibility if
equipment generating this data are modified

Note! Hardware precaution

The interface 2 of Atlas DOLOG systems use current loop outputs, intended
to drive an opto-coupler LED. However, if connected to an NMEA
standard opto-coupler input, the DOLOG output has the incorrect polarity.
It will drive current through the LED in IDLE state but not any current in the
other direction in the other state. This means that polarity conversion must be

3. Hardware considerations
Complying with IEC 1162-1/NMEA 0183 v 2.00 standard. All Consilium
Navigation designed NMEA drivers uses RS485 compatible driver circuits,
using differential outputs swinging in the range 0 to +5 Volts.

All Consilium Navigation designed NMEA input stages use opto-couplers

and we do not recommend any other technical solution for connecting other
equipment to NMEA networks were Consilium Navigation products are
connected as talkers or listeners.
Some early proposals for the IEC 1162-1 permitted also the use of RS422
receivers, having a DC path between case ground and the receiver circuit.
We strongly discourage such use and recommend the use of a separate,
opto-isolated buffer unit if it is necessary to feed such devices.

Calibration and Sea Acceptance Test 701871A2.doc

1. Scope
This document describes the Calibration procedures and also serves as a Sea Acceptance test
(SAT) for SAL R1. The SAT for SAL R1 is used to verify that the system works, and to
calibrate the log. The document contains a list of equipment needed, how to perform the test
and a test protocol.

To aid future customer support, it is necessary that two sets of the protocol pages are filled-in.
One set should be returned to Consilium Navigation After Sales Dpt and the other set should
be left in the reference manual copy on board the ship.

2. Equipment needed
In addition to the log system, the following equipment is needed:
• Calibrated display unit for speed and distance indication (such as SD1-X).
• This SAT instruction.
• For the log calibration a test site is needed, where accurate distance and speed trials can
be made.

3. Test procedure

3.1. The boundary layer

The water moves slower close to the hull than it does further away. The layer with lower
speed is called the boundary layer, see figure A.

At boundary layer edge:
Relative water speed = 100%U Outside boundary layer
(Relative water speed = U)

Figure A Boundary layer speed distribution.

The R1 PCB measures speed close to the hull, and may thus measure a lower speed. When
the ship is in shallow waters, the boundary layer may be different from normal. This physical
effect will affect all logs measuring relative speed.

3.2. Calibration factors

Due to the influence of the boundary layer, calibration factors has to be determined. There are
three different kinds of calibration factors: the draught calibration factors, the the speed-
dependant factors of the multipoint calibration and the transducer calibration factor. The speed
produced by the SAL R1 is thus the actually measured speed, multiplied by the interpolated
speed compensation, the draught factor and the transducer calibration factor.

3.3. Single point draught calibration factor - speed

trial procedure
The system is calibrated by sailing a known distance in calm waters. To eliminate variations
caused by tide, current and wind, the ship should run the same route in both directions. For
each separate run, carefully note true sailed distance and the measured distance on log display.
Then, for each speed, do the following calculation to compute the correction factor CF:

CF = [(expected dist.1 + expected dist. 2) / (sensed dist.1 + sensed dist. 2)].

çConsilium page 4 (10)
Calibration and Sea Acceptance Test 701871A2.doc

It is also possible to use other reference systems like DGPS to obtain the calibration factor.

Then use the menu system to enter the value in menu C2 for the desired draught condition.
Note that the correction shall be expressed as percentage, a calculated value of for example
1.234 shall be entered as 23.40%!

Example:
Assuming that a correction factor of 1.234 was calculated by mile runs or by other means
(meaning that the speed-reading should be 1.234 times the measured speed) the following
steps shall be taken:
• Press MENU to display: ”C0 CALIBRATION, WRITE ACCESS OFF”
• Press ”+” to change to ”WRITE ACCESS ON”
• Press ENTER to go into menu ”C1 DRAUGHT COND, BALLAST1 00.00%”
• Press MENU to go into menu ”C2 DRAUGHT CAL, SET FACTOR”
• Press ENTER to go into the mode ”C2 DRAUGHT CAL, BALLAST1 00.00%”
• (To change calibration factor of any other draught condition, press MENU to change
between BALLAST1, BALLAST2 and FULL LOAD)
• Use ”+” and ”-” to set the factor to the desired value ”+23.40%”
• Press ENTER to store the set value
• Press MENU and ENTER simultaneously three times to go back into normal
operation in the BALLAST1 mode (or any other mode chosen on men C1).

3.4. Multiple point calibration

NOTE! Performing Multi-point calibration results in very good accuracy performance from
the WT log system, but requires multiple speed runs with accurate reference, which is not
always possible to perform during normal shipyard sea trials.

In such situations, the use of single-point calibration is recommended, which is described

above.

3.4.1. The principle of multi-point calibration

If the ship would travel with a higher speed than the maximum calibrated speed, the calibration
factor of this maximum speed will be used. For speeds between the calibration points
interpolation using a linear approach is used to calculate the current calibration factor.

The calibration factor for the speed closest to zero knots will also be the factor used for all
speeds down to zero. However, the low astern speed may have an entirely different
correlation factor, as can be seen in this example:

Figure B An example of the calibration curve after a multi-point calibration.

3.4.2. Performing multi-point calibration

Before the calibration runs, make sure that all calibration factors are set to 00.00%!
For each separate run, carefully note true sailed distance and the measured distance on log
display. Repeat this procedure for each speed required. A maximum number of ten calibration
points at ten different speeds can be used.
After the test runs have been completed, do the following calculation for each speed to
compute the correction factors:
CF = [(expected dist.1 + expected dist. 2) / (sensed dist.1 + sensed dist. 2)].
Use multi-point calibration sub-menus to enter these values.

Example:
Assuming that the following calibration values were obtained during a sea trial, the following
steps would have to be taken:
Expected (Sailed) speed Sensed (measured) speed Calibration factor
10 knots 8.33 knots 1.200
20 knots 18.18 knots 1.100
30 knots 28.57 knots 1.050
Note that the expected speed (corresponding to sailed distance is used as reference point in
the calibration menu. The figure below shows the difference between the expected and the
sensed speed regarding crossover. The reason to use the expected speed as a reference is to
avoid to recalculate the sensed speed when a calibration factor already has been entered into
the speed log. If we for instance would like to add a new point at expected speed 15 knots,
then the calibration factors already is 1.15, and the sensed speed would already contain a

• Press MENU and ENTER simultaneously three times to go back into normal
operation.

3.5. Transducer calibration factor

If a replacement transducer with a defined calibration factor is fitted (this is marked on the
transducer casing and on the cable), enter this value in the menu C4.

Example:
If a transducer with marking TC+123 (= +1.23%) is installed, perform the following steps:
• Press MENU to display: ”C0 CALIBRATION, WRITE ACCESS OFF”
• Press ”+” to change to ”WRITE ACCESS ON”
• Press ENTER to go into menu ”C1 DRAUGHT COND, BALLAST1 00.00%”
• Press MENU three times to go into menu ”C4 TRU CALIBRAT.,MARKING:
TC+000”
• Use ”+” and ”-” to set the factor to the desired value ”TC+123”
• Press ENTER to store the set value
• Press MENU and ENTER simultaneously three times to go back into normal
operation.

4. Test procedure for optional LDU

• Check that the LPU enters normal operation mode and presents the correct speeds to
different users.
The different sections of the manual covers installation and also describes testing procedures
for each sub-unit. Especially the section about the LDU (if this is included) contains useful
information about testing large installations.

If correct operation of all connected indicators and users (radar etc) was not verified during
the tests described in the previous sections, the following procedure can be used to verify
signal flow throughout the system:

a) Go to the menu for simulated speed and enter a value of +8 knots. Leave the log
running in this menu during the rest of the signal flow test.

b) All connected indicators and/or display in LPU (if present) should display this value. If
not, NMEA connection from ELC should be checked.

Also all connected external equipment (via relay or opto-coupler pulses or IEC 1162-
1/NMEA 0183 serial data) should display these values.

SAL-R1 Trouble shooting 701863B1.doc

1. Introduction
This document describes how to trouble shoot a malfunctioning SAL-R1 log system. First a fault
localising scheme is described. After that you find how to test different sub-systems.

2. Fault localisation
When a system malfunction is found for the speed log we follow the flow chart below.

TRU test

ELC test

test

2.1. Subsystem and connection test

Subsystem test is performed first. The goal is to see whether we have an interconnection error, or a
faulty subsystem. The test includes the following steps:
• Open the ELC cabinet. Check mains supply voltage. Check mains supply fuses.
• Check that the LCD panel shows normal operation mode as described in the manual.
• Check that LED-indicators function normally, i.e. TR1 and TR2 are lit, and depending on
condition SIGN and CORR may be lit.

2.1.1. NMEA inspection

Diagnosing the serial messages from SAL 860R is simple with a special cable with two female 9-
pole D-sub connectors. The cable is also used for updating the software for the water track log. The
connectors 1, 4 and 5 on the R1 9-pole D-sub should be connected to the connectors 2, 3 and 5 on
the PC COM-port 9-pole D-sub:

5 GND 5

Figure: Special cable for communicating with SAL R1

2.1.2. R1 Interconnection test

This test simulates speed from the R1 unit to test if any output is faulty.
• Go to the speed simulation menu and enter different speeds, for example +8 knots and –2 knots.
How to change simulated speed is described in chapter on SAL R1 menu system.
• Check that all equipment connected to the log read the simulated speed. An SD1-2 indicator with
presentation of "Err" indicates transmission time-out or bad reception. This might indicate that the
NMEA bus line has been cut. A presentation of ”- - -” indicates unvalid speed, which is
equivalent to correct NMEA messages, but the log being unable to measure the speed.
• Check that the NMEA messages sent from the R1 is correct. NMEA "A" and "B" shall transmit
data as 4800 baud, 8 databits, 1 stopbit and no parity. The SAL R1 is prepared for an
optiononal baud rate of 38400 baud. This is selectable through the menu system, but not yet
implemented in LPU and indicators. See chapter on SAL R1 menu system on how to set this.
Note that if the PC/terminal is connected to signal ground, there will be transmission errors.
• Each NMEA speed message starts with $VDVBW, and end with <CR><LF>. Other messages
for data logging and debugging beginning with $PSAL may be present. If such messages interfere
with other equipment, they may be switched off, see chapter on SAL R1 menu system.
If any of the above tests fails this is a indication of hardware fault. Go back to normal operation
mode to make the R1 measure the real speed of the vessel.

2.2. Transducer (TRU) test

2.2.1. Physical position of TRU

Ensure that TRU is in its most downward position. The TRU position may have changed position
due to external forces. This may give turbulent flow in the water. One way to verify the TRU position
is to make a mark on the connecting tube before unfasten the tube bracket. The connecting tube is
then lifted a few millimetres and then pushed downwards again. The mark shall then be in the same
position as before. Check that the alignment mark on the connecting tube is on the starboard side
and parallel to the keel line. Fasten the tube bracket again.

2.2.2. Electrical test of TRU

Low insulation values indicate a leaky TRU. If values are out of tolerance, exchange TRU and test
system again.
• Disconnect R1 transducer cable from PCB.
• Measure resistance between pins 1-2 and pins 4-5 respectively. The value shall be within the
range 1.3–3.0 ohms. Values outside indicate bad short circuit or bad connection.
• Measure insulation between pins 1-3, 4-3 and pins 1-4 respectively. The value shall exceed 20
MOhms. Lower value indicates a leaky transducer.
• Reconnect R1 transducer cable to PCB.
If the transducer fails the test it shall be replaced.

2.3. PCB test

PCB test shall test whether the electronics works correctly. The production test instruction is a useful
document for this.
• Check that the LCD panel shows normal operation mode as described in the manual.
• Check that LED-indicators function normally, i.e. TR1 and TR2 are lit, and depending on
condition SIGN and CORR may be lit.
• Test R1P conversion of BT by verifying that simulated bottom track speed and depth are shown
correctly in the NMEA output.
• Enter the menu system and select test mode T1 for speed simulation. Adjust simulation to +8.00
knots. This simulates a dummy speed on the outputs. Check NMEA output and indicators.
• Enter menu system and select test mode T2 to test the LED’s.
• Enter menu system and select test mode T3 to test the AGC circuitry with transmitter disabled.
The values on the LCD shall be balanced and low. LED's Tr1 and Tr2 shall be unlit.
• Enter menu system and select test mode T4 to test the AGC circuitry with transmitter enabled.
The values on the LCD shall be balanced and higher than with test T3. LED's Tr1 and Tr2 shall
be lit. The level for T4 depends on the reflector conditions, and may vary a lot.
• Use an oscilloscope to measure the amplitude of the transmit pulses. Values of 25–30 Volts are
normal across terminals 1–3, 2–3, 4–3 and 5–3, where terminal 3 is virtual ground. Check that
the transmitted frequencies are correct (3.8 and 4.2 MHz respectively).
• Enter menu system and select miscellaneous menu M2 to make a reset. The watchdog will reset
the system after two-second timeout. Check that the R1 powers up according to the normal
reset sequence.
• Enter menu system and select debug mode D1 to enable serial data transmission of proprietary
NMEA messages. The information in the message helps diagnose the system if recorded and
sent to Consilium Marine. Note that the debug information may choke other users of NMEA
data as it comes as often as possible.
• The correlation coefficient seen in the LCD (field RC=NNN, FC=NNN or LC=NNN) gives
important information on working conditions for the log. A high correlation coefficient is an
indication of good working conditions for the log. Correlation coefficients of 300–800 are
normal in the Baltic Sea when sailing at 10 knots. Note that this value depends on water
condition, and may thus change with season and location. The value achieved during the sea trial
may be written down and used as a reference value to see if a drastic change has occurred.
If nothing abnormal is found, we may have a receiver hardware fault. Continue with water track
simulation test, where the simulator is connected to the R1 instead of the transducer. This is used by
trained service engineers only.
