1 INTRODUCTION
The log employs electromagnetism as its operating principle.
A magnetic field is produced in the water near the log sensor face. The magnetic field induces an
electrical voltage gradient in this water as it flows past the sensor. This voltage is detected by
electrodes situated on the face of the sensor and passed to the Electronic Unit for measurement, to
provide speed information to the microprocessor.
The electromagnetic principle has several advantages over other methods of measurement:-
a) It is unaffected by changes in draught pressure
b) There are no moving parts or pipes associated with the log sensor
c) The relationship between water speed and sensor output is linear, resulting in high sensitivity at
all speeds.
d) Calibration is unaffected by changes in the water salinity due to the relatively high input
impedance of the measuring circuit.
NOTE!
When the depth of water beneath a vessel is relatively shallow, the flow of water may be
accelerated so that the log shows an increased speed. This does not depend on the type of log,
but on the physical geometry involved. Similarly, the trim of the vessel may influence the
boundary layer conditions to produce a small change in calibration of the log. Such affects
will vary with the shape of the hull and position of the log transducer.
Sea state may cause abnormal fluctuations in the indicated speed and should the transducer
come completely out of the water, the indicated speed may increase to the maximum scale
reading. This will temporarily increase the rate at which distance is recorded.
voltage proportional to the speed of water over the face of the transducer is produced. This is fed into
the microprocessor circuit.
The EM Log Interface also has two digital NMEA 0183 serial outputs meeting IEC 61162-1
requirements, that repeat the messages output from TX Channel 1 of the I/O board, and two pairs of 200
pulses per nautical mile outputs.
NMEA 0183 output speed-log sentences are:- VHW, VBW and VLW. Regarding the VHW
sentence, note that heading is not always transmitted as a null field. If input NMEA 0183 serial data, as
a HDT message, meeting IEC61162-1 standard, from a gyro, for instance, contains valid heading
information, this will be inserted into the appropriate field of the VHW sentence.
Sentences:
$VMVLW,xxxxx,N,xxxxx.x,N,,N,,N*hh<CR><LF> (NMEA 0183 v4.00 / IEC 61162-1: 2010)
$VMVBW,xxx.x,,A,,,V,,V,,V*hh<CR><LF> (NMEA 0183 v4.00 / IEC 61162-1:2010)
$VMVHW,,T,,M,xxx.x,N,xxx.x,K*hh<CR><LF> (NMEA 0183 v4.00 / IEC 61162-1:2010)
Output message frequency is 1 Hz. Note that both NMEA 0183 O/Put ports give all messages (except
proprietary JLG dimmer messages) input to the 5 Channel I/O board (see section 1.2.2) plus those
calculated by the P1100 microprocessor software.
NMEA Drivers are SN75176AP. Output drive capability rated at 1 NMEA load of 500 ohms each port;
providing for a maximum of 2 NMEA listeners (1K0 impedance each) per output port.
Output Channel 5 can also be used for transmission of proprietary Walker/JLG sentences. Any such
messages, input at any of the input channels, are only available for onward connection from Output
Channel 5.
Output Channel 2 is dedicated as a legacy channel and provides serial data, and 24Vdc power, to
earlier Walker P248 Log / P249 Wind and/or P255 Weather Displays. This legacy channel has a
message frequency of 1.5Hz. Use of earlier Walker P255 Weather Displays is only possible, provided
that a P1002 Weather Sensor, or a P1003 Wind and Weather Sensor, is used to provide the required
serial XDR message into the 5 Channel I/O Board.
LEDs are fitted for diagnostic purposes and are covered in section 4.1.3.5
Various Walker Wind Sensors can be connected into the 5 Channel I/O Board.
A combined ultrasonic masthead unit; P292, is available (see drg. 3342-2-7) for connection into any one
of the five input channels. This type of wind sensor outputs a NMEA 0183 MWV serial wind
sentence with the wind speed in knots.
Alternatively, the Walker P296 combined cup and vane unit (see drg. 3343-2-30) can also be used.
Again, this unit also outputs a NMEA 0183 MWV serial wind sentence with the wind speed in knots.
As an alternative to either of the above, a separate wind speed sensor (cup unit) and a separate wind
direction sensor (vane unit); P299 and P300 respectively, can also be used. Two input channels would
be used, one for each type of sensor. Both sentences would be passed on to the microprocessor board
where the wind speed data; from the P299, and the wind direction data, from the P300, would be
extracted before the MWV sentence was re-formulated to include both wind speed and wind direction
data.
Alternatively, IEC 61162-1 (NMEA 0183) MWV sentence/s, described above, may be input
separately, from other talkers, into any available input channel/s.
Full list of IEC 61162-1 (NMEA 0183) sentence formatters that may be input, from other ships
equipment, in order that full functionality of the P1100 unit can be utilised, are as follows:
MWV (either separate sentence with relative wind speed and a further separate sentence with relative
wind direction or as a single sentence containing both relative wind speed and relative wind direction
values)
HDT for heading*.
VTG for speed over ground* / course over ground*.
GGA UTC of position fix / latitude / longitude / GPS quality indicator / number of satellites /
HDOP #.
VHW in absence of a fitted Walker transducer, for a source of speed through the water (secondary
use*) or as an alternative source of heading.
VBW in absence of a fitted Walker transducer for a source of speed through the water (secondary
use*) or, if included, speed over ground (primary use*)
XDR for weather information; if required. A single message is passed through. Note however, that
if a P1263, water temperature sensor is also connected, in addition to a P1002, or P1003, sensor, the
data fields will be re-transmitted as a single string.
After processing, the P1100 unit will combine and output a message string that includes sentences as
follows:-
VHW
VBW
VLW
MWV (relative)
MWV (theoretical)
MWD sentence will be output if a VTG or HDT sentence is input
If XDR / GGA / VTG / HDT messages are input, these too will be output.
Full details of sentences that can therefore be output; providing NMEA input requirements are met, are as
follows:
$VMVHW,,T,,M,xxx.x,N,,K*hh<CR><LF> (NMEA 0183 v4.00 / IEC 61162-1:2010) Note that this

Where two such sensors are specified and fitted; one on the port side and one on the starboard side, a
manual sensor selector switch is available to provide for operator only selection of NMEA 0183
MWV serial data from the appropriate windward sensor. Alternatively a P1812 switch interface is
available to provide automatic selection of serial data from the windward sensor.
Note that the NMEA 0183 MWV sentence transmitted from the solid state wind sensor is read by
the 7080 software before being re-transmitted to any fitted wind data displays or to other connected
receiving equipment.
1.4.4 Combined Cup and Vane Wind Sensor. P296 (Drawing 3343-2-30)
The unit consists of a combined masthead unit incorporating wind speed and wind direction sensors,
which are used to provide serial data of wind speed and wind direction.
This unit consists of two distinctly different sections; an upper vane unit and a lower cup unit
assembly.
A] Cup Unit.
The unit carries a cupset fitted to a stainless steel shaft, which runs in shielded bearings. A cap fitted
to the shaft provides a labyrinth for protection against water ingress. The slotted end of the shaft,
driven by the cupset rotates within an opto-switch carried on the lower PCB of a board assembly
mounted within the carrying tube. Twice per revolution of the cupset, a square wave signal is
produced which is fed directly to a microcontroller. The processor times the duration between
successive pulses and, by using a stored look-up table, appropriate for the cupset concerned, the wind
speed value is calculated.
The cupset is initially supplied separately and will require fitting to the main unit prior to installation
on the vessel. The procedure for fitting the cupset is given below.
1] Remove the retaining nut and the seeloc washer from the drive shaft at the bottom of the main
unit of the P296 sensor. Hold the flanged cap, attached to the drive shaft, steady, in order for
facilitate the unscrewing of the retaining nut.
2] Fit the cupset over the drive shaft ensuring that the location pip in the centre section of the
cupset faces upwards and locates correctly in the hole in the flange of the cap.
3] Replace seeloc washer, re-attach retaining nut and, holding Cupset engaged in cap, securely
lock the retaining nut down onto the washer. Rotate the cupset to check that it runs square
with the drive shaft.
B] Vane Unit.
This unit carries a vane assembly fitted to a stainless steel shaft, which runs in shielded bearings. The
vane cap forms a labyrinth for protection against water ingress. The vane is attached by two set
screws diametrically opposite through the cap itself. The lower end of the shaft, driven by the vane,
carries a circular magnet, which rotates above hall-effect sensors mounted on the upper pcb of the
assembly mounted within the carrying tube. Signals produced as the vane rotates to take up a
position determined by the wind are fed directly to a microcontroller for calculation of wind
direction.
The sensor, attached to a stainless steel arm and block assembly, is provided with a mounting bracket
suitable for securing onto the horizontal surface of the mast top. Two fixing slots are provided in the
base of the mounting bracket to allow for final alignment.
$WIMWV,x.x,R,x.x,N,A*hh<CR><LF>
Note that both wind direction and wind speed fields are variable to xxx.x
Note that, at wind speeds above 100 knots, the status field will show V (invalid
measurement).
Fixed type transducers made from LB4 bronze are for use in steel hulled and in wood/fibreglass
hulled vessels. A fibreglass facing carries the sensing electrodes. The fibreglass is anti-fouled using:
International Paints Interspeed 2000: White anti-fouling paint (non-conductive).
Fixed type transducers made from stainless steel; 316 S16 are for use in aluminium alloy hulled
vessels. A fibreglass facing again carries the sensing electrodes. The fibreglass is again anti-fouled
using: International Paints Interspeed 2000: White anti-fouling paint (non-conductive).
Hull Pads for steel hulled vessels are made from either, a) welding quality mild steel BS970 070M20
with the Phosphorous and Sulphur content, both equal to, or below, 0.045% or b) EN10025
5355J2G3.
Hull Pads for wood/fibreglass hulls are made from Aluminium Bronze NE5833 or equivalent.
Hull Pads for aluminium hulls are made from Aluminium Alloy Grade NE4 [L44].
A fibreglass facing carries the sensing electrodes. The fibreglass is anti-fouled using: International
Paints Interspeed 2000 : White anti-fouling paint (non-conductive).
A seavalved hull fitting assembly is provided for housing the removable transducers. Two types are
available; one for steel hulled vessels, the other for wood/fibreglass vessels.
For steel hulls :-
Hull Pad is made from either a) welding quality mild steel BS970 070M20 with the Phosphorous and
Sulphur content, both equal to, or below, 0.045% or b) EN10025 5355J2G3; to meet required
international welding specifications.
Note : The above specifications may be altered without notice. Any changes made would not affect
the functioning of the equipment and hull integrity would not be compromised.
2. INSTALLATION
A boundary layer condition exists beneath any vessel. Within this layer, the velocity of the water
differs from the true speed of the vessel through the water. As the sensing position is moved further
aft, the thickness of this layer increases. This results in the signals from the transducer getting
smaller and smaller. For this reason, the transducer should always be placed well forward. Where a
bow thrust propeller is fitted to the vessel, a position below the athwartships tube and slightly
forward of the tube centre line in a fore and aft direction may be found satisfactory and will often
provide reasonable access inside the hull for wiring and servicing.
In addition to boundary layer considerations, it is generally found that a steadier speed indication is
obtained from a forward fitted transducer. It should be remembered, of course, that the transducer
MUST remain in solid water under all reasonable sea conditions and when the vessel is in ballast.
The transducer is then offered up to the pad and carefully inserted, making sure its O ring stays in
its correct position in the groove of the transducer flange. The transducer should be pushed up into
the pad as far as possible where it will remain in position due to the adhesion caused by the sealing
compound.
The stainless steel retaining ring (Item 2) should be passed over the cable and screwed onto the top
of the transducer with the three stainless steel socket head screws slackened back so that the ring can
be screwed down as far as the steel pad. By tightening the three socket head screws, little by little,
the transducer body will be drawn up into its final position and the sealing compound forced out in
an annular ring round the edge of the transducer flange outside the vessel. The retaining ring (item 2)
will probably require repositioning i.e. screwing down a bit further as the sealing compound is forced
out. The arrow on the top of the transducer must finally be aligned towards the flow of water, which
is normally from the bow of the vessel, but may be a few degrees different where the curvature of the
hull is such as to change the direction of the flow when the vessel is under way. The retaining ring
should be finally screwed down as far as possible by hand and the three socket head screws evenly
tightened until the transducer is secure and the O ring compressed.
Finally, wipe off the excess sealing compound from the transducer face MAKING SURE THAT
THE ELECTRODES THEMSELVES (Item 3) ARE COMPLETELY CLEAN AND FREE FROM
ANY GREASE, ANTI-FOULING PAINT etc. Ensure that the external part of the steel pad has been
anti-fouled and provides a smooth surface over which the water can flow. Any anti-fouling used on
the transducer face must be non-conductive and at all times the electrode beads must be clean and
free of any paint or grease.
For aluminium alloy hulls the above procedure still applies, but the hull reinforcing pad is made from
a suitable welding quality alloy and the transducer itself is manufactured in stainless steel and not
bronze as referred to above.
2.3.1 Skin fitting with seavalve for steel hulls (drawing 2900/4/1-1)
The valve is bolted to a steel reinforcing pad by means of the studs provided and a gasket fitted
between the two faces. The steel pad is welded both internally and externally to the shell plating.
After welding the external surface of the pad must be painted to protect against corrosion and to
ensure a clean surface over which the water will flow.
A brass flange containing an O ring seal is bolted to the top of the valve. A second O ring is
compressed between the top of this flange and the flange on the transducer. Two steel pillars project
upwards from the valve and a steel bridge piece holds them in position at the top.
A stainless steel lead screw is permanently fitted with a cross bar for rotation and hence provides for
the raising and lowering of the transducer. This screw rotates in a bronze nut fastened to the centre of
the bridge piece, and has the transducer attached to its lower end.
With the lead screw rotated anti-clockwise to the limit of its travel, the lower face of the transducer
is approximately 10mm above the gate valve, which can, therefore, be closed.
By unbolting the upper bridge piece, the lead screw and transducer can be removed from the
assembly.
A hole 154mm in diameter is cut in the hull. The seavalve should be detached from the steel pad,
together with the lower gasket. The pad is then passed through the hole in the hull and welded both
internally and externally. Note that the position of the tapped holes relative to the fore and aft line is
not important, but the seavalve hand wheel can only be set in one of four positions. Where the
position of the hand wheel is critical, it is suggested that the pad be tacked in place and the valve
offered up to the pad temporarily, to ensure that the hand wheel is accessible. The valve should then
be removed while the welding is completed. When the pad is cold the seavalve and its gasket should
be positioned on the pad and fastened with the studs/nuts/washers provided.
The upper flange of the valve will have been supplied with the pillar assembly already in position.
To fit the transducer, remove the two bolts/washers (Items 3 and 4) and detach the upper bridge piece
(item 5) and lead screw (item 6). From the lower bridge piece (item 7) unbolt the two short pillars
(items 8 and 9) and screw them into the top flange of the transducer. Attach the lead screw and lower
bridge piece to these pillars with the hex head bolts supplied.
With the seavalve closed, the transducer is entered into the upper flange and seal using a little grease
on the brass tube. Keep the bridge piece in line with the main pillars so that when the transducer has
entered the O ring seal, it is not forced down onto the valve gate and damaged. The bridge piece
should come to rest in its correct position against the tip of the pillars before the face of the
transducer makes contact with the valve gate.
DO NOT ALLOW ANY GREASE TO GET ON THE BOTTOM FACE OR ELECTRODES.
Refit the bolts (item 3) not forgetting the lock washers. With the lead screw fully anti-clockwise the
lower face of the transducer clears the valve gate, and therefore the valve can now be opened fully
and the transducer wound down to its working position. This is with its lower face flush with the
face of the steel pad.
The transducer has a dot or arrow engraved on its flange and this should point forward into the flow
of water with the vessel moving ahead. The alignment can be corrected by using a bar or large
screwdriver as a lever placed between the two short pillars (item 8) BEFORE the transducer is fully
lowered into position.
When fitting a replacement with the vessel afloat, it will be necessary to open the valve slightly once
the transducer has entered the O ring seal. Otherwise the water trapped between the valve gate and
its bottom face will prevent the transducer being fully entered into the valve chamber.
2.3.2 Skin fitting with seavalve for wood/GRP hulls (drawing 2905/4/2-1)
The valve is bolted through the hull to a bronze fairing block by means of studs provided. A brass
flange, containing an O ring seal for the transducer is bolted to the top of the valve. Two steel
pillars project upwards from the flange/valve and a steel bridge holds them in position at the top of
the assembly.
A stainless steel lead screw is permanently fitted with a cross bar for rotation and hence provides for
the raising and lowering of the transducer. This screw rotates in a bronze nut fastened to the centre of
the bridge piece with the transducer attached to its lower end. Rotation of the lead screw causes it to
be raised or lowered.
With the lead screw rotated anti-clockwise to the limit of its travel, the lower face of the transducer
is approximately 10mm above the gate valve, which can therefore be closed. By unbolting the upper
bridge piece, the lead screw and transducer can be removed from the assembly.
IMPORTANT : The Hull may need localised strengthening around the position of the seavalved skin
fitting. This is more likely to be required in the case of GRP hulls and the installer must take note of
GRP thickness at the position concerned. Weights involved are:
Transducer : 11.3 kg (including 50m cable)
Seavalved skin fitting : 24.7 kg
A hole 70mm in diameter is cut in the hull. The bronze fairing block should have the four studs
screwed into it and offered up to the hull, having previously drilled four corresponding holes using
the spacer (item 1) as a template.
Note that the orientation of the seavalve is not important and it should be positioned so that there is
easy access to the hand wheel for opening and closing. The brass liner (item 2) should be inserted
through the hull and into the fairing block, and the spacer (item 1) dropped over the liner and
clamped down against the planking using the nuts provided. The thickness of the planking will not
be known in advance and it is necessary for the liner to project above the spacer (item 1) by 8mm.
After marking, cut or machine the liner to the correct length. It is essential that no frays or sharp
edges be left at either end which could prevent the transducer from passing through.
Having removed the liner and machined it, the fairing block and studs should be well covered with a
suitable sealing compound and repositioned in the hull. The spacer should also be coated with a
sealing compound paying particular attention to any irregularities in the planking as it is essential
that a water-tight joint is produced between this spacer and the planking. A gasket (item 3) is
positioned over the studs together with the sleeve (item 4) which helps register the valve. The valve
should then be fitted to the assembly and bolted down by using the nuts and washers provided. The
design is suitable for hulls up to 75mm thick. For thinner hulls, it may be necessary to shorten the
studs so they clear the valve body.
The upper flange of the valve will have been supplied with the pillar assembly already in position.
To fit the transducer, remove the two bolts/washers (items 5 and 6) and detach the upper bridge piece
(item 7) and lead screw (item 8), from the lower bridge piece (item 9). Unbolt the two short pillars
(item 10) and screw them into the top flange of the transducer.
Attach the lead screw and lower bridge piece to these pillars with the hex head bolts supplied.
With the seavalve closed, the transducer is entered into the upper flange and seal above the valve,
using a little grease on the brass tube. Keep the bridge piece in line with the main pillars so that when
the transducer has entered the O ring seal, it is not forced down onto the valve gate and damaged.
The bridge piece should come to rest in its correct position against the top of the pillars before the
face of the transducer makes contact with the valve gate.
Refit the bolts (item 5) not forgetting the lock washers. With the lead screw rotated fully anti-
clockwise, the lower face of the transducer clears the valve gate and, therefore, the valve should now
be opened FULLY and the transducer wound down to its working position. This is with its lower
face FLUSH with the face of the fairing block. The two nuts on the upper part of the lead screw
should be rotated until the lower one is tight against the bronze nut in the upper bridge piece. The
second nut is locked tightly against the other, so that at any future date, the transducer can be
removed and refitted or replaced in the knowledge that the face of the transducer will indeed be flush
with the outer face of the fairing block when wound down to this pre-determined position. THIS
INITIAL SETTING PROCEDURE MUST BE DONE WITH THE VESSEL OUT OF THE
WATER.
When fitting a replacement transducer with the vessel afloat, it will be necessary to open the valve
slightly once the transducer has entered the O ring seal. Otherwise the water trapped above the
valve gate will prevent the transducer being fully entered into the valve chamber.
The transducer has a dot or arrow engraved on its flange and it should point forward into the flow of
water, with the vessel moving ahead. This alignment can be corrected by using a bar or large
screwdriver as a lever and placing it between the two short pillars (item 10) BEFORE it is
completely lowered into position. The lead screw should be tightened down fully clockwise, using
the cross bar fitted and HAND PRESSURE ONLY.
It is the low level of this voltage, proportional to the vessels speed, which can cause problems when
other unrelated a.c. voltages are induced into the cabling and interfere with the signal being
measured. For this reason it is preferred that the transducer cable is encased in a solid steel pipe up to
within a few centimetres of the Electronics Unit. Although the speed signal is synchronously
detected after amplification, other high level induced voltages can interfere with the correct operation
of the log. The steel pipe provides magnetic screening from adjacent cables carrying heavy
alternating currents for other equipment. The normal non-ferrous braiding or screening does not
prevent such pick-up. It is also good practice to use this pipe for earthing the electronics unit to the
skin fitting or the hull adjacent the skin fitting, thus minimising any large earth current loops. This is
particularly so, when problems are experienced with interference from high power MF & HF radio
transmitters.
2.5.1 Wiring:
When connecting cables during installation, personnel involved must take full ESD
(electrostatic discharge) precautions. The wearing of a suitable grounding strap is
recommended.
2 core screened cable (0.5 CSA), is required for connecting to the 200 ppNM relay contacts in the
Electronic Unit.
2 core screened cable (0.5 CSA), is required for connecting to any IEC 61162-1 (NMEA 0183) serial
input or output on the 5 Channel I/O board in the Electronic Unit.
2 core screened cable (0.5 CSA), is required for connecting to the IEC 61162-1 (NMEA 0183) serial
outputs on the Transducer PCB in the Electronic Unit.
NOTE that the casing of the Electronic Unit must have a good low impedance earth. Consequently, a
suitable bonding must be provided directly to the ships earth from the unit. The steel pipe containing
the transducer cable should be bonded at its upper end to the Electronic Unit, and the lower end of
the steel pipe bonded to the hull adjacent to the transducer.
On wood/GRP vessels it is even more essential to have a good earth connection and it is suggested
that such earthing be through to the steel pipe containing the transducer cable and the transducer skin
fitting at the lower end.
In the interests of EMC, wherever practicable, cable screens should be bonded to earth. In the
Electronic Unit, there are connection points provided for screen connections.
Due to variances in the outside diameter of the transducer cable it may be advantageous to use a
smear of silicone grease on the outside of this cable before passing it through the gland concerned.
2.7.1 Wiring:
When connecting cables during installation, personnel involved must take full ESD
(electrostatic discharge) precautions. The wearing of a suitable grounding strap is
recommended.
The main P1248 Log Data Display (speed and distance indicator) requires a 3 x twisted pairs cable
with overall screen (cores 0.5 CSA min), for NMEA, power & reset. Note again that this indicator
would normally share the same 24Vdc supply as the P1100 master electronics unit.
Additional P1248 Log Data Display/s would normally require a twin twisted pair cable (0.5 CSA
min), for NMEA and power, which could be provided via the main P1248 Log Data Display. Refer
to the P1248 connection diagram, 3419-A3-11 for full information.
The relay; RLY1 (N.O. and Com connections) of the main, or single, P1248, can be used to reset the
TRIP distance in the LOG. RLY1 will be active for 1 second after the TRIP RESET button has been
pressed for 5 seconds. This 5 seconds activation time is implemented to prevent accidental operation
and reset of Trip distance.
The display will automatically go to Display Mode 2 (Log Speed and Trip Distance) after TRIP
RESET has been pressed.
For TRIP RESET operation, with a common 24Vdc supply to both the P1248 and P1100 Master
Electronics Unit (MEU), connect Terminal 12 on the LOG transducer board, in the MEU, to
RLY1(N.O.) on the P1248 and connect RLY1(Com) to 0V, using permanent link on rear of the
P1248 Display. The option link on the P1100 MEU transducer board must be in the Right Hand
position (centre and R.H pin connected). See drawing 3419-A3-11 sheet 2.
For TRIP RESET operation with an independent 24Vdc supply into the main or single P1248
Display, connect Terminal 11 on the LOG transducer board, in the P1100 MEU, to the independent
+24V. Connect Terminal 12 on the LOG transducer board, in the MEU, to RLY1(N.O.) on the
P1248 and connect RLY1(Com) to the independent 0V, again using permanent link on rear of the
P1248 Display. Note that the option link on the P1100 MEU transducer board must be in the Left
Hand position (centre and L.H pin connected) for this configuration.
The P1249 wind data display, and P1255 weather data display both require a 2 core screened cable
(0.5 CSA), for NMEA, together with a separate 2 core screened cable (0.5 CSA), for power.
IF WIND SENSORS OTHER THAN THE P292 OR P296 ARE EMPLOYED, REFER TO
DATA SHEETS FOR THE SENSORS SUPPLIED WITH THE SYSTEM.
2.8.1.1 Wiring:
The P293 sensor cable supplied is 4 core with an overall screen and has the connector attached.
Standard cable length is 20 metres, but longer lengths; up to a maximum of 200 metres, can be
supplied to order. The cable must be secured at regular intervals to eliminate any strain on the
attached connector when mated with the sensor lead and also to prevent chafing. Mated
connector is rated at IP68. The cable is considered to be class 2 in respect of its carried low voltage
power and signal levels. Refer to section 2.8.3 and sub-sections 2.8.3.1 / 2.8.3.2 for full details
concerning cable installation.
IMPORTANT:
The sensor is a precision instrument and care should be taken when handling.
If the unit is removed at any time, ensure that the in-line connector attached to the cable is
suitably protected from the elements until such time as the sensor is refitted.
DO NOT REMOVE THE BLACK RUBBER TRANSDUCER CAPS.
2.8.1.3 Cleaning:
If there is any build up of deposit on the sensor unit, it should be gently cleaned with a cloth,
moistened with soft detergent. Solvents should not be used, and care should be taken to avoid
scratching any surfaces.
If exposed to extreme low temperatures and precipitation causing a build up of ice in the measuring
chamber, the unit should normally be allowed to defrost naturally. However, tepid water can be
sprayed onto the unit to speed up the process if required. Do NOT attempt to remove ice or snow
with a tool.
Do NOT remove the black rubber transducer caps.
2.8.1.4 Servicing:
There are no moving parts or user-serviceable parts requiring routine maintenance.
Opening the sensor unit or breaking the security seal will void the warranty and the calibration.
In the event of failure it is recommended that all cables and connectors be checked for continuity,
bad contacts, corrosion etc.
If it is necessary to remove the sensor unit at any time, do not separate the sensor from its flanged
tower but remove as a complete unit after disconnection of the masthead connector. Protect both
halves of the separated connector from the elements until reconnection can be carried out.
2.8.2.1 Wiring:
The P293 sensor cable supplied is 4 core with an overall screen and has the connector attached.
Standard cable length is 20 metres, but longer lengths; up to a maximum of 200 metres, can be
supplied to order. The cable must be secured at regular intervals to eliminate any strain on the
attached connector when mated with the sensor and also to prevent chafing. Mated connector is
rated at IP68. The cable is considered to be class 2 in respect of its carried low voltage power and
signal levels. Refer to section 2.8.3 and sub-sections 2.8.3.1 / 2.8.3.2 for full details concerning cable
installation.
Having visually aligned the Mounting Bracket (A), sufficiently tighten the securing screws used to
hold the bracket in position. Re-fit the main unit (B); the combined wind sensor, arm and block
assembly, and secure, using the four M5 pozi-pan head screws and lock washers (C) provided; two
on each side of the bracket. With the P293 cable assembly connected, hold the vane steady, as if the
vessel is head to wind, and check with bridge personnel that the reading, on the fitted digital wind
display, is 0. If necessary, adjust the position of the mounting bracket until the required result is
achieved. Lock the mounting bracket in position when correct alignment has been achieved. If the
combined sensor is not going to be fitted immediately ensure that the connector of the P293 cable
assembly is protected from the elements until such time as the P296 is fitted. The 4 core screened
cable of the P293 is fed through the mast using suitable synthetic rubber grommets top and bottom,
or appropriate glands. If the cable is brought down the mast externally, it should be secured at regular
intervals to prevent chafing. Leave enough slack cable at the mast top to allow the connector to be
attached and to be removed from the P296 main unit (B).
If the P296 is to replace an earlier Walker combined masthead unit, it is likely that an original
Walker mounting plate is fitted directly to the mast top. This flat plate will be found to contain two
threaded studs, protruding vertically, which will align with the slots in the P296 mounting bracket
(A). The nuts and washers, attached to these studs, must be removed and the mounting bracket (A),
with the main unit (B) attached, positioned over the studs, and the washers and nuts re-fitted. The
P296 must then be correctly aligned, fore aft, as described above, before locking it securely in
position on the fitted mounting plate using the nuts and washers concerned.
If part installation is carried out with either the sensor assembly or the down cable assembly being
fitted then it is important to protect the appropriate connector from the elements until it can be mated
with its other half.
IMPORTANT:
The sensor is a precision instrument and care should be taken when handling.
If the unit is removed at any time, ensure that the in-line connector attached to the cable is
suitably protected from the elements until such time as the sensor is refitted.
2.8.2.3 Cleaning:
If exposed to extreme low temperatures and precipitation causing a build up of ice, which may
prevent the rotation of the vane or cupset, the unit should normally be allowed to defrost naturally.
However, tepid water can be sprayed onto the unit to speed up the process if required. Do NOT
attempt to remove snow or ice with a tool.
2.8.2.4 Servicing:
There are no user-serviceable parts requiring routine maintenance.
In the event of failure it is recommended that all cables and connectors be checked for continuity,
bad contacts, corrosion etc. Check that both cupset and vane are able to rotate freely.
If it is necessary to remove the sensor unit at any time, first unscrew and release the P293 cable
connector from the back end of the P296 unit and protect the in line connector of the P293 from the
elements. Release and remove the M5 screws and lock washers from the sides of the mounting
bracket and remove the P296 main unit; the combined wind sensor, arm and block assembly. Re-fit
the screws and lock washers to the mounting block on the main unit for safe keeping.
The cupset can be replaced if damaged. Replacement cupset re-order code is 01-034-296 and whilst
replacement fitting instructions are also included, the procedure is given below.
Note:
For replacement purposes, if accessibility to the fitted sensor is difficult then, rather than attempt
replacement of the cupset at the fitted position, it is recommended that the main unit of the sensor be
removed, as outlined previously, and replacement of the cupset carried out elsewhere. Remember to
protect the disconnected cable connector from the elements whilst the main unit is removed.
Procedure:
1] Hold Cupset securely by hand and with spanner, slacken, unscrew and remove retaining nut
together with seelok washer.
2] Remove Cupset by lowering vertically off drive shaft.
3] Replace new Cupset ensuring that pip in centre section is correctly located in hole in flange of
cap.
4] Replace seelok washer, re-attach retaining nut and, holding Cupset, engaged in flange of cap,
securely lock retaining nut down onto washer.
If remote changing of the cupset was carried out:
5] Re-fit the main unit of the sensor securely back onto its mounting. Ensure that original alignment
is maintained.
6] Re-connect the P293 cable connector checking that it is correctly and securely mated.
Vane replacement:
In the event of damage to the fitted vane, the main unit must be removed, as outlined earlier, and
returned to John Lilley and Gillie Ltd, for replacement of the vane to be carried out.
Class 2 is for cables carrying slightly sensitive signals, such as ordinary analogue (i.e. 4-20mA, 0-
10v and signals under 1MHz), low rate digital communications (i.e. RS422, RS485), and digital (i.e.
on/off) inputs and outputs (e.g. limit switches, encoders, control signals). Cables carrying NMEA
0183 serial data, or other available analogue signals, from the 7070 master unit are included in this
class, as are the connecting cables from the Walker Wind Sensors, Weather Sensor and Water
Temperature Sensor.
Class 3 is for cables carrying slightly interfering signals, such as low voltage AC distribution (<1kV)
or DC power equal to or above 48v. This class also covers control circuits with resistive or inductive
loads where the inductive loads are suppressed at the load.
Class 4 is for cables carrying strongly interfering signals. This would include all the power inputs or
outputs, to or from, adjustable speed motor drives, power converters; and their DC links. Cables to
RF transmitting antennae and unsuppressed inductive loads are also included in this class.
Class 5 and 6 are reserved for MV and HV supply distribution cables respectively. Note that any
other cable classes in proximity to these would need to be protected by additional screening or very
much greater spacing.
450mm
450mm
600mm
Class 5 cables are not shown in the diagram above but should be at least 150mm spacing from Class
4, with Class 6 at least a further 150mm away. Where any such MV or HV cable is within 1 metre of
a Class 1 cable, the Class 1 cable should be run in a covered metal duct.
Greater spacings generally give lower coupling (crosstalk) between cables; however the acceptable
amounts of coupling will always depend on the types of cables, the installation techniques used, the
electronics connected to each end of the cables and the functional requirements of the application.
Running individual cable classes in their own closed metal duct or round conduit PECs allows the
spacing between classes to be reduced (even to zero), but it is still best to avoid running classes 1 and
4 close together.
Note that type approved equipment that includes IEC60945 certificated accreditation will be immune
from interference levels stated in the standard, providing that the installation of the said equipment
has been carried out strictly in accordance with manufacturers instructions.

the [3] key.
4.1 The LCD display will show ENTER SPEED(x10) with E = ENTER C =
CANCEL below.
To SET a fixed speed value from the keypad, the required speed should be entered in
the form [1][0] to represent 1.0 knots or [1][0][0] to represent 10 knots. Note that
these are examples only and the actual key presses made are to customer
requirements. This is useful for setting up other equipment that is being connected to
the 7080, such as other indicators, and for checking the 200 pulses per nautical mile
(PPNM) outputs; if enabled. Note that keyed values less than 1 knot and greater than
80 knots will be ignored.
After keying in the required set speed correctly, for instance 100 for 10.0 knots, the
LCD will show ENTER SPEED (100) / E = ENTER C = CANCEL. Press [E] to
accept the previously keyed set speed.
The LCD will show TEST MODE C = CANC / SPEED 10.0 Knots. The indicated
(set) speed will be output as the relevant field within the IEC61162-1 VHW
(NMEA 0183) message, with the associated VLW message (note: total distance
transmitted in whole number nautical miles on legacy channel 2 only) also being
output. If the 200PPNM outputs have been previously enabled, they too will pulse at
the test speed frequency.

The inputted information is retained in non-volatile RAM. Note that, after successful calibration, the
LCD will show P1100 LOG / CALIBRATED. The appropriate vessel speed and trip distance
values will be shown on the Log Data Display/s fitted on the system concerned.
WARNING: After satisfactory calibration, if accessing the LCD configuration menu screen,
pressing key [4] RESET to bring up the CLEAR MEMORY? / C = CONT E-END prompt
and pressing key [C] and then key [E] after the ARE YOU SURE? prompt is displayed, will
permanently erase all log calibration data from the look-up table. Trip and Total
distances and System Up Time would also all be reset to zero. ONLY USE THIS FACILITY
IF IT IS INTENDED TO PERFORM RE-CALIBRATION OF THE 7080 SYSTEM.
2.9.2 Zero Control (See also section 2.9.3 Calibrating the 7080 Log Function (Calibration
methods)
The Zero potentiometer, VR2, is located on the transducer PCB, within the screened can, in the
Electronic Unit, (refer to drawing F-1877 Transducer PCB assembly). This control is used to set the
indicated speed to zero when the water is stopped relative to the vessel. Access is gained through the
hole in the lid and, using a suitable screwdriver, the spindle of the potentiometer should be turned
clockwise until a speed reading is given on the LCD and/or log indicator. It should then be turned
anti-clockwise VERY slowly, until the speed has dropped to zero or just above. IT IS IMPORTANT
THAT THE ZERO CONTROL IS NOT TURNED TOO FAR ANTI-CLOCKWISE, as this will lead
to errors, particularly at low speeds.
The procedure to SET ZERO is performed as part of the overall CALIBRATION procedure and
is accessed from the CONFIGURATION MENU. All calibration runs are performed AFTER
zero has been adjusted to read correctly. Refer to section 2.9.3.
NOTE: Once a calibration has taken place the information can only be removed by using the
RESET function within the configuration menu of the 7080. This will erase ALL calibration
data.
The KNOWN SPEED method of calibration, works on the principle of performing a single run in
one direction only and requires that the speed of the ship be calculated. The calculated KNOWN
SPEED is then entered into the look-up table as described later. At the point of entering the
KNOWN SPEED into the look-up table, the vessel must continue steaming ahead at the same
engine revs as when the vessels speed was calculated. This ensures that the sensed transducer
voltage, at the instant of entering the calculated speed value, is correct. The calculated KNOWN
SPEED is entered via the keypad, using the x10 rule, such that, for example, pressing [1][0][0]
[Enter], would input 10.0 knots.
This KNOWN SPEED method of calibration can also be used in conjunction with an accurate and
reliable on board GPS system. Rather than calculating the vessel speed as previously described, the
SOG (speed over ground) given by the GPS can be used. Again, when inputting the speed value, the
vessel must continue steaming ahead, at the same engine RPM, as when the GPS SOG reading was
taken. Using GPS for this method of KNOWN SPEED calibration is only recommended for use in
those areas where small tidal flow conditions are known to exist.
It is recommended that after setting zero the upper limit of the system is calibrated, i.e. maximum
speed ahead. Further calibration can be done, at other forward speeds, within this upper limit, so that
a range of calibration points is available. Note that whilst a maximum of fifty calibration points can
be input into the P1100 7080 look-up table, normally only three or four would be considered
necessary. Do not calibrate log at speeds that are too close to each other. This calibration procedure
is outlined in more detail later.
The KNOWN DISTANCE method of calibration works on the principle of performing the
calibration by sailing the vessel over two runs, the second the reciprocal of the first, both over an
identical measured nautical mile distance (minimum 0.2NM, maximum 5.0NM) and with the same
engine revs. Sensed transducer voltages are taken once per second during both runs. At the end of
the second run, calculation of the average speed through the water, over both RUN 1 and RUN 2,
is performed automatically, whilst an average of all the sensed transducer readings is also calculated.
The calculated average speed and the averaged sensed transducer reading, are automatically stored in
the look-up table. It is recommended that after setting zero the upper limit of the system is calibrated,
i.e. maximum speed ahead. Further calibration can be done, by repeating the method, at other
forward speeds, within this upper limit, so that a range of calibration points is available. Note again
that whilst a maximum of fifty calibration points can be input into the P1100 7080 look-up table,
normally only three or four would be considered necessary. The absolute minimum of calibration
points that may be used is two.
This method of calibration is considered to be more accurate than the known speed method as tidal
stream effects have been nullified, many more sensed transducer readings have been taken and
averaging is used in the automatic calculating process for the derivation of speed through the
water.
Do not calibrate log at speeds that are too close to each other. This calibration procedure is outlined
in more detail later.
The GPS MILE (D/T) method can be used, to provide an automatic calibration procedure, only if a
IEC 61162-1 (NMEA 0183) GGA sentence is being input to the P1100 from an approved GPS
shipboard system. The vessel would again be sailed over two runs, the second the reciprocal of the
first, with both runs performed over a 1 nautical mile distance over the ground, as calculated and
timed, by the P1100 from the received GGA messages. Both runs are performed at the same
engine revs. Sensed transducer readings are taken once per second and averaged at the end of Run 1,
and at the end of Run 2. The average of both these transducer readings is calculated and this is tied
to the calculated average speed over the ground from the sensed distance travelled with respect to
time over both runs. If the calibration details from the two runs concerned, shown on the 7080 LCD,
appear satisfactory, they can be accepted by the operator, and the calibration point stored in the look-
up table. Note again that whilst a maximum of fifty calibration points can be input into the P1100
7080 look-up table, normally only three or four would be considered necessary.
The following GPS NMEA sentences can be used for calibration of the LOG.
GGA HDOP
(continued)
<= 3 then latitude,
longitude fix
regarded as valid
These sentences are also checked for validity and passed through to TX channels 1, 1A, 1B, 3, 4 and
5.
NOTE:
ANY OF THE ABOVE CALIBRATION METHODS CAN ONLY BE USED AFTER THE 7080
SPEED LOG HAS BEEN CORRECTLY ZEROED. This should only be performed by an
authorised person and is achieved by adjusting the potentiometer (VR2) in the main unit, within the
screened can on the transducer printed circuit board. Refer to earlier section 2.9.2.
Switch off unit, remove link and re-connect transducer wires. Switch unit back on. After the
P1100 software version has been momentarily displayed, P1100 (LOG) /
UNCALIBRATED will be displayed on the LCD. Follow the previous instructions to
return to the Configuration Menu and then to the Calibration Menu. A small speed value
will, however, be displayed on the main P248 Log Data Display, indicative of the movement
of water presently passing the face of the log transducer.
Press [C] to return to the ENTER SPEED (x10) / E = EN B = RPT C = CAN screen.
Other additional calibration points may now be added to the 7080 look-up table, in order to
provide the best possible calibration of the system.
3) Perform another run at a lower speed (different engine revs), and steer vessel at the new
speed, again on a straight course and repeat instructions given above at 2), to store a second
calibration point. FIXING CAL POINT / PLEASE WAIT will appear for a few seconds,
before changing to show 02 CAL PTS SET / C = EXIT. Press [C] to return to the ENTER
SPEED (x10) / E = EN B = RPT C = CAN screen.
Note that, after the initial 01 calibration point has been stored in the 7080 look up table, if
any subsequent calibration point entered; at the [E] key press, is considered to be incorrect,
then the programme will not allow the suspect calibration point to be stored. ENTRY
ERROR CAL / POINT NOT STORED will be displayed and the LCD screen will revert to
the ENTER SPEED (x10) screen for the calibration, at the same or other speed, to be done
again.
4) Perform other runs, at other speeds, as considered necessary to achieve the most satisfactory
calibration of the system on the vessel concerned.
In total, a maximum of fifty calibration points can be stored. Three or four calibration points
are normal but if the vessel involved does change attitude in the water with respect to speed
then more may be necessary to ensure that an acceptable standard of accuracy is achieved.
5) Note that if a mistake is made in keying in the correct known speed value, in knots, using
the x10 rule, then, provided that the incorrect value has not been entered, press key [B]. The
LCD will show the ENTER SPEED ( ) / E = EN B = RPT C = CAN screen ready to
repeat the keying in of the x10 known speed value.
6) When it is decided that enough known speed calibration points have been entered, at the
ENTER SPEED (x10) / E = EN B = RPT C = CAN screen, press [C] to return to the
Calibration Menu. Press [C] to return to the Configuration Menu. Press [C] to return to
the normal run mode screen whereupon the LCD will show P1100 (LOG) /
CALIBRATED.
Two calibration points are recommended as the minimum for a displacement type craft (one that
does not change its attitude in the water whether sailing at high or low speeds). A calibration point at
the top speed of the vessel and a calibration point at a slower speed (minimum 5 knots) would be
the minimum recommended for storing in the look-up table of the P1100 (7080). The speed range
of the vessel concerned does affect the decision making process in the determination of the number
of calibration points necessary to provide the best operational results. Faster craft would normally
require more calibration points to be used.
Vessels with planing type hulls that cause the vessel to change attitude in the water at different
speeds are recommended to use a minimum of four calibration points to produce the best operational
results.
It is important that calibration log speeds chosen are not too close to each other. A minimum of 2
knots between adjacent known speeds must be observed.
PROCEDURE.
Switch off unit, remove link and re-connect transducer wires. Switch unit back on. After the
P1100 software version has been momentarily displayed, P1100 (LOG) /
UNCALIBRATED will be displayed on the LCD. Follow the previous instructions to
return to the Configuration Menu and then to the Calibration Menu. A small speed value
will, however, be displayed on the main P1248 Log Data Display, indicative of the
movement of water presently passing the face of the log transducer.
4) Provided that the entered input distance is within the accepted limits given in 3), the LCD
will display E TO START RUN 1 / C TO CANCEL.
Bring the vessel up to top speed and, steering a straight course, wait for speed to settle before
passing the start marker and commencing RUN 1 over the known measured distance.
5) Press key [E] at the very start of the measured distance; ie, as the vessel passes the start
shore marker. The system will immediately begin taking readings of the sensed transducer
voltage once every second. The LCD will show E = STOP RUN 1 XXXX / A = ABORT
C = CANCEL. (Where XXXX will be the time of RUN 1 in seconds)
6) Press key [E] at the very end of the RUN 1 measured distance; ie, as the vessel passes the
end shore marker.
Provided that the elapsed time is within the system parameters, in respect of calculated speed
through the water, the LCD will show E TO START RUN 2 / C TO CANCEL.
7) WITHOUT SLOWING DOWN, steer the vessel in a 180 turn, to bring the vessel around
and onto the reciprocal (or parallel) reverse RUN 2 course, as near as possible through the
same stretch of water sailed through originally at RUN 1.
8) Press key [E] at the very start of the reciprocal RUN 2 (ie, as the vessel passes the
measured distance start shore marker). The system will again immediately begin taking
readings of the sensed transducer voltage once every second. The LCD will show E = STOP
RUN 2 XXXX / A = ABORT C = CANCEL. (Where XXXX will be the time of RUN
2 in seconds)
9) Press key [E] at the very end of the RUN 2 measured distance; ie, as the vessel passes the
end shore marker.
Provided that the elapsed time is within the system parameters, in respect of calculated speed
through the water, the LCD will show FIXING CAL POINT / PLEASE WAIT for a few
seconds before showing 01 CAL PTS SET / C = EXIT.
10) Perform another set of runs at a lower engine rev setting (lower speed). Again bring vessel to
the new speed and, steering a straight course, parallel to the shore markers, wait for speed to
settle before commencing RUN 1 over the same measured distance.
From the Calibration Menu, repeat the keying instructions given above from 2) through to
9) to store a second calibration point at this new speed.
Note that, at any time during a calibration procedure, if it is deemed necessary to ABORT the
calibration run being performed, press the [A] key.
In the case of a RUN 1 calibration being aborted, the LCD will revert back to the E TO START
RUN 1 / C TO CANCEL screen, ready for the RUN 1 to be started again. Repeat RUN 1 with the
vessel sailing over the same measured distance.
In the case of a RUN 2 calibration being aborted, the LCD will revert back to the E TO START
RUN 2 / C TO CANCEL screen, ready for the vessel to repeat the calibration RUN 2 concerned.
If, at any time during the calibration procedure, it is decided to end calibration, press the [C] key.
The LCD will revert to show the Calibration Menu. NOTE: any calibration points previously
stored from completed calibration runs will remain in the look-up table.
In total, a maximum of fifty calibration points can be stored.
Two calibration points are recommended as the minimum for a displacement type craft (one that
does not change its attitude in the water whether sailing at high or low speeds). A calibration point at
the top speed of the vessel and a calibration point at a slower speed (minimum 5 knots) would be
the minimum recommended for storing in the look-up table of the 7080. The speed range of the
vessel concerned does affect the decision making process in the determination of the number of
calibration points necessary to provide the best operational results. Faster craft would normally
require more calibration points to be used.
Vessels with planing type hulls that cause the vessel to change attitude in the water at different
speeds are recommended to use a minimum of four calibration points to produce the best operational
results.
It is important that calibration log speeds chosen (determined from setting engine revs) are not too
close to each other. A minimum of 2 knots difference in speed, between adjacent known distance
calibration points, must be observed.
PROCEDURE.
2.9.3.3 Zero Setting & Calibration using GPS MILE (D/T) Method.
Switch off unit, remove link and re-connect transducer wires. Switch unit back on. After the
P1100 software version has been momentarily displayed, P1100 (LOG) /
UNCALIBRATED will be displayed on the LCD. Follow the previous instructions to
return to the Configuration Menu and then to the Calibration Menu. A small speed value
will, however, be displayed on the main P248 Log Data Display, indicative of the movement
of water presently passing the face of the log transducer.
3) The LCD will ONLY show GPS MILE RUN 1 / E = START C = CANCEL, if the
necessary fields, relating to quality indicator, number of satellites and HDOP, all
contain values as specified in the GGA GPS table on page 46.
The GPS MILE (D/T) method involves calibrating the Log over a 1 nautical mile distance
travelled as calculated from a GPS Start Point and a GPS End Point. The Log is
calibrated by doing two runs, the second (RUN 2) being the reciprocal of the first run (RUN
1), as near as possible through the same stretch of water sailed through originally. Both runs
are performed at the same engine revs.
Bring the vessel up to top speed and, steering a straight course, wait for speed to settle.
Press key [E] to begin the GPS Mile (D/T) calibration method.
4) The system will immediately begin taking readings of the sensed transducer voltage once
every second.
The LCD will show X.XXX NM YYY.Y S / A = ABORT C = CANCEL.
(X.XXX will be the calculated nautical mile distance travelled and YYY.Y will be the time
of the GPS RUN 1 in seconds).
5) When the vessel is calculated to have travelled exactly 1 nautical mile, the average of all the
sensed transducer readings taken during RUN 1 is tied to the average speed of the vessel over
the ground calculated from the time taken to travel the 1 nautical mile distance.
The LCD will show SOG XX.XX N / E = RUN 2 C = CANCEL.
XX.XX will be the calculated average SOG (Speed over Ground) in Knots from RUN 1.
Press [E] to accept and temporarily store the data.
6) The LCD will now show GPS MILE RUN 2 / E = START C = CANCEL.
WITHOUT SLOWING DOWN, steer the vessel in a 180 turn, to bring the vessel around
and onto the reciprocal (or parallel) reverse RUN 2 course, as near as possible through the
same stretch of water sailed through originally at RUN 1.
Press [E] to begin RUN 2 of the GPS MILE (D/T) calibration procedure.
7) The system will immediately begin taking readings of the sensed transducer voltage once
every second.
The LCD will show X.XXX NM YYY.Y S / A = ABORT C = CANCEL.
(X.XXX will be the calculated nautical mile distance travelled and YYY.Y will be the time
of the GPS RUN 2 in seconds).
8) When the vessel is calculated to have travelled exactly 1 nautical mile, the average of all the
sensed transducer readings taken during RUN 2 is tied to the average speed of the vessel over
the ground calculated from the time taken to travel the 1 nautical mile distance. The average
of both these RUN 2 values and the previous RUN 1 values is calculated to produce the
average SOG reading over both runs. The average of the transducer readings from both RUN
1 and RUN 2 is automatically tied to this average SOG value.
The LCD will show AV SPEED XX.XX N / E = SET 2 C = CANCEL.
XX.XX will be the calculated average SOG (Speed over Ground) in Knots from both RUN 1
and RUN 2.
Press [E] to accept and store the data.
9) The LCD will show FIXING CAL POINT / PLEASE WAIT for a few seconds.
Provided that the calibration point has been successfully set, the LCD will then show 01
CAL PTS SET / C = EXIT.
Press [C] to exit to the Calibration Menu
If the calibration point was not accepted then the LCD would show CAL POINT ERROR
for a few seconds before automatically reverting to show the Calibration Menu screen.
Other additional calibration runs may now be performed to add further calibration points into
the 7080 look-up table and so provide the best possible calibration of the system.
10) Perform another set of runs at a lower engine rev setting (lower speed). Again bring vessel to
the new speed and, steering a straight course, wait for speed to settle before commencing
GPS MILE (D/T) RUN 1.
From the Calibration Menu, repeat the keying instructions given above from 2) through to
9) to store a second calibration point at this new average speed from performing another set
of runs.
If, at any time, it is required to exit from the GPS MILE (D/T) calibration function, press the [C]
key. The LCD will revert to show the Calibration Menu screen.
If, at any time, the GGA message received, fails to comply with the minimum requirements
specified for GPS MILE (D/T) calibration; given on page 46, the display will show NO GPS
DATA / C=CANCEL. Press [C] to revert back to the Calibration Menu screen.
Vessels with planing type hulls that cause the vessel to change attitude in the water at different
speeds are recommended to use a minimum of four calibration points to produce the best operational
results.
It is important that calibration log speeds chosen (determined from setting engine revs) are not too
close to each other. A minimum of 2 knots difference in speed, between adjacent GPS MILE (D/T)
calibration points, must be observed.
After any simulation checks have been completed using the built-in log simulator, THE
SWITCH MUST BE RETURNED TO ITS NORMAL RUN POSITION, OTHERWISE
THE LOG WILL NOT OPERATE WHEN UNDER WAY.

direction fields, which, if input, is directly processed. One of these units can be used as an alternative
to the separate cup unit and vane unit mentioned above.
Various other serial data sentences, as per IEC 61162-1 (NMEA 0183), can be input via any of the five
opto-isolated RS422 input ports on the 5 channel I/O board in the P1100 Electronics / Control Unit.
IEC 61162-1 (NMEA 0183) sentences that will be accepted by the 7080, P1100, Electronics
Unit are:- HDT, VHW, VBW, MWV, GGA, VTG and XDR. XDR messages may be
input from a Walker P1002 Weather Sensor, or P1003 Combined Wind and Weather Sensor. XDR
from a Walker P1263 Water Temperature Sensor can also be input.
User control is achieved by means of a 16 key, 4 x 4 matrix keypad, labelled 0-9 and A-F.
The unit is designed to operate from a 24 volt DC supply provided either directly or via a separate
PSU.
A push button reset for the trip distance has been incorporated into the 7070 (7080) P1248 log data
display. Where more than one log data display is included in the system, the master log display
would normally share the same 24Vdc supply as the P1100 (7080) electronics unit and would have the
reset line connected.
IEC 61162-1 (NMEA 0183) serial data for log speed (VHW, VBW and VLW) and wind
indication (MWV, both relative and theoretical, and MWD, True to North). Available on 6
output channels (Ch1, 1A, 1B, 3, 4 and 5).
Dedicated NMEA 0183 Legacy channel (Ch2) providing VHW, VLW, MWV and
MWD. XDR, if input from a P1002 Weather sensor, is passed through.
Visual display to the user on a 16 character by 2 lines LCD display.
200 pulses per nautical mile, on potential free relay contacts. 2 pairs of contacts are available.

The majority of the keys only perform a simple switching task, changing what can be displayed on
the LCD. Note too, that the eleven individual readings *, available for display on the LCD, are only
present for some 3 seconds after pressing the appropriate button on the keypad. After this time the
LCD will revert to show the normal run screen.
Note that if the values being read, in response to any of these keys being pressed, exceeds the
number of digits displayable on the LCD, that a row of asterisks would result. The number of
asterisks displayed would equal the normal number of characters allowed within the field in
question. For instance, if the relative serial wind speed data being input was 110.0 knots, then
pressing key [6] would display **** on the LCD as only values up to 99.9 knots are displayable for
wind speed. In such instances, the associated transmitted MWV serial wind sentence, from the
P1100, would still include full wind speed information in the data field concerned.
There are, however, very important functions, which must be called up using the keypad. All these
are available from using key [0] Setup Options, and include Calibration procedures. These
functions, all available from the resultant Configuration Menu, shown on the LCD, allow the
operator to set up the configuration of the P1100 and generate the calibration table used to calculate
the speed of the ship. The Configuration Menu is protected by the PIN number, so that only those
who are authorised to do so can alter the P1100 setup. Refer to section 2.9 and flow charts for full
information.
Once the system has been configured and calibrated, it should not be necessary to use this routine
again, except for any board (or transducer) changes, which require that the setup or calibration
information be updated.
In any situation where the system requires the operator to enter a number, then the [E] key will be
used as an [Enter] key. All keys pressed by the operator, as described by this manual, are indicated
by italics.
3.2.1 7070/7080 Log Data Display / Speed and Distance Indicator: P1248
Note: In the event of more than one P1248 Log Data Display being fitted, the main navigational
Display will be wired in to provide the trip distance reset facility.
The unit has two 256*64 pixel OLED Graphic displays, 4 Touch switches; for trip reset, trip and
total distance display modes and illumination control, 4 NMEA 0183 inputs and 1 NMEA 0183
output.
Two Modes of operation are provided. In Mode 1, the top display will show Speed through the
water, in knots, with the lower display showing Total distance travelled through the water, in
nautical miles. In Mode 2, the top display will show Speed through the water, in knots, with the
lower display showing Trip distance travelled through the water, again in nautical miles. Displayed
readings meet the requirements of IEC 62288: 2008, for the presentation of navigational-related
information on shipborne navigational displays. Operational controls likewise reflect the appropriate
requirements specified within this standard.
The P1248 Log Data Display will accept and re-transmit valid IEC 61162-1: (NMEA 0183)
messages with the following formatters; MWV, MWD, VLW, VHW, VBW, HDT, HDM, HDG,
VTG, JLG (proprietary), GGA, XDR and MTW. LEDs, visible at the rear face of the unit, provide
additional information for customer confidence and diagnostic purposes.
The display has illumination up [] and down [] touch switches, which allow dimming to
extinction. The indicator is splash-proof but is not waterproof.
The P1248 is designed as a peripheral unit to the 7080 P1100 Master Electronics Unit.
Normal On/Off switching of system power is provided by the P1100 MEU.
If switched off, the previous mode and level of illumination are retained in flash memory.
3.2.2 The 7070/7080 Wind Data Display (Speed and Direction Indicator): P1249
The unit has two 256*64 pixel OLED Graphic displays, 4 Touch switches; for display mode, scaling
and illumination control, 4 NMEA 0183 inputs and 1 NMEA 0183 output. A ring of LEDs in 5
steps also indicates wind direction.
Relative, True or True to Ship, wind direction is also indicated on the ring of LEDs as appropriate to
the activated display mode.
Displayed readings meet the requirements of IEC 62288: 2008, for the presentation of navigational-
related information on shipborne navigational displays. Operational controls likewise reflect the
appropriate requirements specified within this standard.
The P1249 Wind Data Display will accept and re-transmit valid IEC 61162-1: (NMEA 0183)
messages with the following formatters; MWV, MWD, VLW, VHW, VBW, HDT, HDM, HDG,
VTG, JLG (proprietary), GGA, XDR and MTW. LEDs, visible at the rear face of the unit, provide
additional information for customer confidence and diagnostic purposes.
The display has illumination up [] and down [] touch switches, which allow dimming to
extinction. The indicator is splash-proof but is not waterproof.
If switched off, the previous mode and level of illumination are retained in flash memory.
The unit has two 256*64 pixel OLED Graphic displays, 4 Touch switches; for display mode and
illumination control, 4 NMEA 0183 inputs and 1 NMEA 0183 output.
Two MODES of operation are provided. In Mode 1, activated by pressing on the Pr mBar key,
the top display will show barometric pressure and trend, with the lower display showing air
temperature. In Mode 2, activated by pressing on the Rh % key, the top display will show
humidity with the lower display showing water temperature. All temperature readings are shown in
degrees Celsius, barometric pressure is given in millibars and humidity as %.
The unit can thus be switched between Modes to display Barometric Pressure / Trend and Air
Temperature, or Humidity and Water Temperature.
Displayed readings meet the requirements of IEC 62288: 2008, for the presentation of navigational-
related information on shipborne navigational displays. Operational controls likewise reflect the
appropriate requirements specified within this standard.
The P1255 Weather Data Display will accept and re-transmit valid IEC 61162-1 (NMEA 0183)
messages with the following formatters; MWV, MWD, VLW, VHW, VBW, HDT, HDM, HDG,
VTG, JLG (proprietary), GGA, XDR and MTW. LEDs, visible at the rear face of the unit, provide
additional information for customer confidence and diagnostic purposes..
The display has illumination up [] and down [] touch switches, which allow dimming to
extinction. The indicator is splash-proof but is not waterproof.
If switched off, the previous mode and level of illumination are retained in flash memory.
INPUT MESSAGES:
The following messages may be input to the 5 Channel I/O board within the P1100 Master
Electronics / Control Unit. Note that whilst talker ID is unimportant to the interrogation of
sentences, checksum calculations are always taken into account for validity purposes.
1 $--VHW,x.x,T,x.x,M,x.x,N,x.x,K*hh<CR><LF>
Note that the P1100; with log enabled, would use information in the heading field only for
calculation of true wind values. The P1100 would disregard any information in the water
speed fields and would construct its own VHW sentence using transducer derived water
speed values for re-transmission. With log disabled, heading and water speed data would be
used by the P1100 to calculate true wind values.
2 $--VBW,x.x,x.x,A,x.x,x.x,A,x.x,A,x.x,A*hh<CR><LF>
This sentence would only be separately input if the P1100 had Log disabled and would be
used as the source for water speed. Note that the P1100, with log disabled, would only use
the first, longitudinal, speed through the water knots field in the above message. Anything
in the other fields is discarded. Any of these unused fields may be nulls. If P1100 had log
enabled, then own VBW message would be derived using speed values calculated using
inputs from the fitted transducer.
3 $--HDT,x.x,T*hh<CR><LF>
Note that this message is used for P1100 True wind calculations only.
4 $--MWV,x.x,R,x.x,N,A*hh<CR><LF>
Note that the above message, if containing both wind speed and wind direction fields, can be
input via a single input port on the 5 Channel I/O Board. If two separate messages were to be
input, one containing data in the wind speed field only and the other containing data in the
wind direction field only, then 2 input ports on the 5 Channel I/O Board would have to be
utilised.
This sentence would normally only be separately input on 7080 installations where a Walker
wind sensor was not included. The sentence is necessary in order to generate and output a
MWV Theoretical (true to ship), or a MWD sentence, from the P1100 Master
Electronics / Control Unit.
5 $--GGA,hhmmss.ss,llll.ll,a,yyyyy.yy,a,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh<CR><LF>
This sentence is used for automatic GPS calibration purposes only.
6 $--VTG,x.x,T,x.x,M,x.x,N,x.x,K,a*hh<CR><LF>
This sentence is used for course over ground (COG) and speed over ground (SOG) data.
The P1100 calculates True Wind Angle and Speed and also Theoretical Wind Angle and Speed from
the best available data.
NMEA 0183 data on any of the five input channels is extracted from VHW VBW HDT VTG and
MWV (Relative) sentences and, together with Speed Through Water from the EM LOG, is used to
calculate True and Theoretical Wind Angle and Speed. This data is then sent to output channels 1,
1A, 1B, 3, 4 and 5 as NMEA MWV (Theoretical) and NMEA MWD sentences.
The accuracy of the calculated results is dependant on what data is available. The following table
indicates what data is available in the IEC 61162-1 (NMEA 0183) sentences used by the P1100.
OUTPUT MESSAGES:
1 $VMVHW,,T,,M,xxx.x,N,,K*hh<CR><LF>
2 $VMVBW,x.x,x.x,A,x.x,x.x,A,x.x,A,x.x,A*hh<CR><LF>

7 $--GGA (if input / as input)
8 $--VTG (if input / as input)
9 $--XDR (if input / as input)
Resultant output messages will be dependant upon the supplied 7080 system component
composition, the IEC 61162-1 messages input and system configuration. The following information
gives a general overview of sentence transmission requirements.
Sentences 1, 2 and 3, are always transmitted on 7080 systems that include a Walker EM Log
Transducer provided that system Configuration has been carried out correctly with the log
ENABLED.
Sentence 4 is transmitted on 7080 systems that include either type of Walker combined wind sensor,
separate Walker wind sensors, a P1003 Wind and Weather sensor, or separately input MWV
(relative) sentence/s.
Sentences 5 and 6 are transmitted on 7080 systems that include a Walker EM Log Transducer
together with either type of Walker combined wind sensor, or separate Walker wind sensors.
Additionally a HDT and / or VTG sentence/s is/are required. Note that separately input MWV
(relative) sentence/s can be used, instead of being provided from fitted Walker wind sensor/s.
Sentences 7, 8 and 9 are only transmitted if the 7080 system has these same messages being input.
Note that whatever combination of messages are actually transmitted, by the P1100 Master
Electronics Unit, all such messages are available at each set of NMEA output terminals apart from
Channel 2 (on the I/O board) which is the dedicated legacy channel for use with P248 Log, P249
Wind and P255 Weather indicators only.
In respect of the NMEA outputs of the 5 Channel I/O PCB, in the P1100 Master Electronics Unit,
NMEA drivers are MAX3442E and output drive capability is rated at 1 NMEA load of 500 ohms
each port.
4 MAINTENANCE
SUITABLE ESD PRECAUTIONS MUST BE TAKEN WHENEVER INSTALLATION /
MAINTENANCE (FAULT FINDING) IS CARRIED OUT. SUCH PRECAUTIONS MUST BE
MAINTAINED DURING REMOVAL / REPLACEMENT OF ELECTRONIC SUB-
ASSEMBLIES AND, IN THE EVENT OF HAVING TO RETURN ANY PIECE OF
ELECTRONICS, ESD SAFE PACKAGING MUST BE USED.
Whilst the above periodic inspection is recommended, longer periods between transducer inspections
are acceptable, provided that no degradation in accuracy of log readings is noticed during normal
equipment operation. If any inaccuracy of readings is noticed and transducer checks outlined in
section 4.1.3 prove that the transducer is satisfactory and the 7080 master electronic unit operates
correctly in simulator mode, then the transducer should be removed for inspection and cleaning as
outlined above. In the unlikely event that some inaccuracy in readings is still evident, then this
unusual occurrence could be due to marine growth fouling the hull just forward of the transducer
position and affecting the normal pattern of water flow present when the log was first calibrated. Re-
calibration of the log system is recommended if such a situation was to develop. The hull would need
to be inspected when the vessel is next dry-docked.
Any anti-fouling of the shell plating (hull) must be carried out in accordance with recommendations
specified in sections 2.3.1, 2.3.2 and 4.1.3.3.
Visual Checks:
1) Once the vessel has been dry-docked, ensure that the face of the EM Log Transducer can be
safely accessed and inspected from the outside of the shell plating.
2) Check that both the Transducer Electrode Beads are intact, are clean and are correctly
positioned relative to the normal water flow.
a) The beads should be projecting from the face of the transducer and should be
relatively identical in size.
b) The beads should not have been painted and should not be covered in grease or marine
growth.
c) The beads should be positioned athwartships so that the normal water flow, when the
vessel sails ahead, is at right angles to an imaginary line through both beads.
3) Check that the face of the Hull Pad, welded to the shell plating, is clear of any marine growth,
which would interfere with the normal water flow across the face of the fitted (or lowered)
transducer.
4) Check that the surrounding area within at least a 1 metre radius from the centre of the transducer
is likewise reasonably free of marine growth.
Electrical Checks:
5) Switch off power to the EM Log system Main Electronics Unit (or Main Control Unit) and
disconnect the transducer cable from the transducer terminals within this main unit.
6) Twist the red and the black cores together; these are the connections to the electrode beads
themselves. Red is the port side electrode bead, black is the stbd side electrode bead.
7) Using a DVM (or analogue meter), check for continuity by measuring across the beads on the
outer face of the transducer. If found to be open circuit then, providing that no junction box is
fitted to extend the transducer cabling, the transducer is defective and must be replaced. If one
or more junction boxes have been utilised to extend the normal 50 metres of transducer cable
permanently fitted to the transducer, then this/these must be inspected as the open circuit could
be associated with the red or black bead connections within the junction box(es).
8) Untwist and separate the red and the black cores ready for further tests or for future re-
connection to the Main Electronics / Control Unit.
9) With the transducer cable still disconnected from the Main unit terminals, again use a DVM (or
analogue meter), set to ohms, to check the coil resistance by measuring across the brown and
yellow cores of the transducer cable. The coil resistance should be approximately 900 to 1000
ohms.
10) With the transducer cable still disconnected from the Main unit terminals, again use a DVM
(or analogue meter). Measurements should be > 100M ohms between;
a) Yellow to Screen.
b) Brown to Screen.
c) Yellow to Black.
d) Brown to Red.
Notes:
Visual checks 3) and 4) are of general interest if, prior to dry-docking, the log system had been giving
suspect readings.
Any scraping / cleaning of the hull carried out whilst the vessel is in drydock, and subsequent anti-
fouling, must, when carried out locally to a fixed type transducer, be performed in a manner that
ensures that the face of the transducer, and especially the electrode beads themselves, are not damaged
during these operations. A sea-valve type transducer can be raised to eliminate any possibility of
damage.
See section 4.1.3.3 for information relating to anti-fouling of the face of the transducer and of the hull
pad.
All the above Electrical Checks; 5) to 10) inclusive, are valid for any replacement transducer that is
fitted with the vessel in drydock.
For Fixed Type EM Log Transducers and for Seavalved Type EM Log Transducers wound down
into working position.
Visual Checks:
Electrical Checks:
2) Use a DVM (or analogue meter), set to ohms. Transducer cable disconnected from the
Main Electronics / Control unit terminals.
a) Connect one test lead to ship Earth; shell plating, steelwork etc, use other lead as
follows:-
Red wire to Earth = Black wire to Earth.
Figure obtained does depend on test meter used + seawater conductivity. As a general
guide, 500 ohms to 200K ohms could be measured.
If there is any doubt concerning the results obtained from the above check then the
following test can also be performed.
Immediately switch meter to measure volts DC, and, if continuity O/K, then decaying
voltage should be seen; very approximately 1 volt decaying.
3) With the transducer cable still disconnected from the Main Electronics / Control unit
terminals, again use a DVM (or analogue meter), set to ohms, to check the coil resistance by
measuring across the brown and yellow cores of the transducer cable. The coil resistance
should be approximately 900 to 1000 ohms.
4) With the transducer cable still disconnected from the Main unit terminals, again use a DVM
(or analogue meter). Measurements should be > 100M ohms between;
a) Yellow to Screen.
b) Brown to Screen.
c) Yellow to Black.
d) Brown to Red.
Note:
A Seavalved Type EM Log Transducer (P99 or P201) can be removed from the seavalved skin fitting
whilst the vessel is afloat. THE TRANSDUCER MUST FIRST BE RAISED AND THE GATE
VALVE THEN CLOSED BEFORE THE REMOVAL OF THE TRANSDUCER. Continuity
testing can then be performed as outlined in Section 4.1.3.1, as per notes 5) to 8) inclusive, rather than
as outlined in Section 4.1.3.2, as per note 2) above.
When carrying out any fault finding, personnel involved must take full ESD (electrostatic
discharge) precautions. The wearing of a suitable grounding strap is recommended.
If log readings are lost, then before any electrical tests; outlined in 4.1.3.1 and 4.1.3.2, are performed on
the transducer itself, it is advised that, in the first instance, the availability of the correct coil drive
voltage to the transducer be checked.
This drive; of 115v, 27.5Hz, for the transducer coil winding, is generated on the transducer PCB,
located in the Master Electronics Unit.
2) Disconnect the brown and the yellow transducer wires from terminal 17 and terminal 18
respectively.
4) Use a DVM, set to measure A.C. volts, and measure across the vacated terminals (17 and
18) on the transducer board.
Note that the frequency of 27.5Hz is set automatically by a timer circuit involving a string of fixed
resistors; R6 (12K), VR1 (8K2) and R11 (10K), capacitor; C7 (0.68uF) and integrated circuit; IC5
(NE555N) on the transducer PCB. To check this frequency an oscilloscope or frequency meter must be
used.
If the correct coil drive voltage is available and if the points outlined in the General Notes section
4.1.3.3 have been covered, then the transducer checks outlined in 4.1.3.1 or 4.1.3.2 (as appropriate)
must be carried out.

When carrying out fault finding, personnel involved must take full ESD (electrostatic
discharge) precautions. The wearing of a suitable grounding strap is recommended.
Before proceeding with any of the checks given below however, first refer to section 4.1.3.5
covering the diagnostics LEDs on the 5 Channel I/O board within the P1100 7080 Master
Electronics Unit, in order to check transmission of required IEC 61162-1 (NMEA 0183)
messages.
Any loss, interruption or corruption of input serial data will cause the associated displays to revert to
show dashes as per the information provided within the Display Mode sections of the P1248 Log
Data Display Data Sheet. Refer to this separate Data Sheet for more details concerning Display Mode
operational characteristics.
In the first instance, remove the P1248 indicator from the panel concerned and check all LEDs at the
rear panel of the unit. Check CPU OK LED to ensure processor is running. Dependent upon status of
Valid and Data LEDs, check all connected Talkers as appropriate, including serial data
transmitted from the P1100, 7080 master electronic unit.
If the problem is found to be a loose input NMEA 0183 connection, re-connect the cable core/s
concerned. Incoming serial data will be restored to the display and digital readings will recommence.
If associated talkers are transmitting correct serial data and if connections at the talker/s and at the
P1248 unit are satisfactory, then continuity of the serial data transmission cable/s, from the talker/s
itself/themselves, must be checked.
If the fault is found to be within the P1248 log data display itself, the unit must be returned for
investigation / repair.
4.2.1.1 Maintenance
For P299 Cup Unit and P300 Vane Unit, see maintenance sections of appropriate product data
sheets.
