2080 Mk2 SOLID STATE WIND SYSTEM
1.0 GENERAL DESCRIPTION.
The basic system consists of a solid state wind sensor and a wind data display. The sensor uses timed
measurements of ultrasonic pulses of sound between transducers located on the lower face of the
airflow chamber to measure wind speed and wind direction. Signal processing is used to provide
NMEA 0183 serial wind data which is transmitted to provide indication of wind speed and direction.
The Wind Data Display reads the transmitted information and provides readings of relative wind
speed and wind direction. The digital displays of wind speed and wind direction are set inside a ring
of LED’s, which give an “analogue” display of wind direction.
Power supply requirement is 24vDC and connection between the indicator and masthead unit is by a
four core screened cable and plug assembly. A standard 20 metre cable assembly is normally provided
but longer lengths can be supplied to order.
1.1 SOLID STATE WIND SENSOR. See drawing 3342-2-7 (ref: P292)
The acoustic sensing technique coupled with state-of-the-art signal processing gives the head the
ability to provide accurate measurement of wind speed and direction over an extensive range. The
design overcomes the inherent problem of gust identification created by the slip streaming of
traditional cup type anemometers and offers high performance without routine maintenance or
calibration.
A flanged tower carries the sensor assembly and the symmetrical arrangement of the acoustic chamber
and the materials used results in a very robust and lightweight unit with no moving parts. The wind
speed and wind direction measurements are made across the measurement plane within the transducer
sensing area with the resultant information sent to the wind data display in NMEA0183 serial format.
This digital signalling makes the cable length to the display arbitrary, unlike some traditional current
loop driven devices, which may need compensation for cable resistance and can be susceptible to
error created by induction along the cable. Correct orientation of the sensor is essential and this aspect
is covered later; see section 2.1.2 “SENSOR ORIENTATION”.
IMPORTANT: DO NOT REMOVE THE BLACK “RUBBER” TRANSDUCER CAPS.
WARRANTY IS VOID IF THE BLUE SECURITY SEAL IS DAMAGED OR
BROKEN, OR IF THE TRANSDUCER CAPS HAVE BEEN DAMAGED.
1.2 WIND DATA DISPLAY. See drawing 3036-2-10 (ref: P249)
The wind data display has two arrays of 7-segment LED displays, the top array of three digits and the
bottom array of four digits. These are inset in a ring of 72 LED’s spaced at 5° intervals which give a
display, analogous to a pointer, in respect of wind direction.
The top array is used to indicate wind speed, which can be read in either “Knots” (KTS), “Metres per
Second” (MPS) or “Kilometres per Hour” (KPH). There are three separate LED’s immediately to the
right of this display. One of these LED’s will be lit to indicate the particular wind speed unit being
displayed.

1.2 WIND DATA DISPLAY; continued:
The lower array is used to display the wind angle in degrees off the bow of the vessel on ship systems,
or off “North” on fixed land based systems. A negative sign indicates wind on the port side of the
vessel on ship systems or from a Westerly direction on a fixed land based system. This relative wind
direction will also be shown by the appropriately lit LED on the outer ring LED display.
A NMEA 0183 retransmit facility is in-built into the wind data display for use as required. Regarding
the transmitted data, the NMEA 0183 sentence formatter is “MWV” and the reference field is set to
Relative only. The full sentence is $IIMWV,xxx,R,xxx.xx,N,A*hh<CR><LF>. Note that this outputs
wind speed in knots.
The display has illumination keypad controls which allows dimming to extinction, and also gives full
lamp test facilities. It is supplied in a Din 43700 pattern case with 144mm square bezel. The indicator
has a splash-proof overlay but is not waterproof.
After connecting the equipment, and upon first switching on, the wind data display will read zero for
a few seconds before displaying the actual data transmitted by the sensor. The initial level of
illumination can be adjusted as required using the appropriate keypad switches; see section 1.2.1
“Operation of the Wind Data Display”.
1.2.1 OPERATION OF THE WIND DATA DISPLAY.
The unit requires a 24vDC supply and must be connected through to the solid state masthead unit
using the screened cable assembly provided. Once connected and with power switched on, the display
will read the transmitted serial data and display readings accordingly.
Switching between the three different wind speed units is achieved by pressing and releasing both
illumination buttons, [∆] and [∇] simultaneously. The indicator LED’s to the right of the wind speed
display window will change to indicate the new unit selected.
The intensity of the LED’s can be altered; including dimming to extinction, to preserve night vision,
by pressing the up [∆] and down [∇] arrow buttons as appropriate.
Note that upon first switching on there is a slight delay of a few seconds until the display reads the
transmitted information.
The “Lamp Test” facility is accessed by pressing the [L/T] button.
On this system the [T/R] button is not used. Pressing this button would cause the “T” above the
button to either flash or be lit continuously. In both of these instances the display would not operate.
In correct operation the “T” is not lit.
Note that if the serial data transmitted from the sensor is interrupted for any reason, the display will
begin to flash. If the transmitted data is not restored the display will then go blank. If this situation
occurred and was found to be caused by a loose connection, re-connection of the cable core
concerned, carried out without switching off the 24vDC supply to the display, would not in itself
restore direct readings until the [∆] button was pressed.

2.0 INSTALLATION.
2.1 ULTRASONIC WIND SENSOR.
The unit should be mounted as high as possible in air which is undisturbed by movement over and
around any structures and in a position to ensure a clear azimuth. The base flange must be attached to
a suitable horizontal platform. For shipborne use, fitting high on the main mast is recommended as
under adverse sea state conditions there would be less possibility of the sensor being frequently
washed with sea water than if mounted forward.
Always check the installation to ensure the solid state sensor is not affected by other equipment
operating locally, which may not conform to current standards, e.g. radio/radar transmitters, engines,
generators etc.
Guidelines:
• Avoid mounting in the plane of any radar scanner – a vertical separation of at least 2m
should be achieved.
• Radio transmitting antennas; the following minimum separations (all around) are
suggested:-
• VHF IMM – 1m
• MF/HF – 5m
• Satcom – 5m (avoid likely lines of sight)
• Ensure that the system is connected in accordance with the diagram supplied and that
if a junction box is used ensure that cable screens are connected through to maintain
EMC integrity.
2.1.1 WIRING.
The sensor cable supplied is 4 core with an overall screen and has the connector attached. Standard
cable length is 20 metres, but longer lengths 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.
Cable information is as follows:
Power:- Red: = +24vDC, Blue = -ve,
Yellow = NMEA 0183 Signal Line A, Green = NMEA 0183 Signal Line B,
Screen = Ground.
See Drawing F-1835 for connections.
(Cable Assembly = ref: P293; always specify length if requiring replacement.)
2.1.2 SENSOR ORIENTATION.
Orientation of the sensor tower is important. The unit must be mounted vertically on its base
mounting flange so that the datum marks; two arrows, a blue rectangle, and an alignment notch, point
directly along the required measurement axis. On a vessel this would be pointing forward, towards the
bow and be parallel with the fore-aft axis. On a static installation the sensor should be aligned with
the datum marks pointing towards North. Provision must also be made for exiting the flying lead /
connector beneath the sensor flange prior to connection; see drawing 3342-2-7. On installation,
always ensure that the connector is securely mated.

SENSOR ORIENTATION. Continued
Slots in the base mounting flange allow for any final adjustment that may be deemed necessary to
attain correct alignment. Simply slacken the three bolts concerned and rotate the unit on its base. Re-
secure when the correct alignment is achieved.
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.
DO NOT REMOVE THE BLACK “RUBBER” TRANSDUCER CAPS.
WARRANTY IS VOID IF THE BLUE SECURITY SEAL IS DAMAGED OR REMOVED.
2.2 WIND DATA DISPLAY.
A mounting plate is provided so that the wind data display can be readily fitted into panels with cut-
outs conforming to that shown on drawing 3035-2-11, and secured in position using screws at the four
corner fixings. Removal of the indicator from the panel is therefore easy, requiring only external front
panel access. Close control of the cut-out’s dimensions is not critical.
Alternatively, the wind data display can be mounted directly into a panel without using the mounting
plates provided. This, however, necessitates access to the rear of the panel concerned in order to fit
and tighten the securing clamps provided. Removal of the display for servicing etc would also require
such rear panel access. In order to mount the display in this way, a square cut-out of 138.0mm +/-
0.25mm (5.435” +/- 0.010”) sides is required with 90° corners.
In the chosen fitted position, access to the in-built keypad switches along the bottom of the wind data
display fascia is necessary for the control of the LED illumination level and “lamp test” facility.
2.2.1 WIRING.
A two core cable (0,5mm CSA) with overall screen is required for connection of the 24vDC power
supply.
A two core cable (0.5mm CSA) with overall screen is required for serial data connection.
(This applies to the NMEA 0183 input from the solid state sensor and the NMEA 0183 output
“re-transmit facility”, available at the wind data display, for use if required.)
Cable entry into the wind data display is via cable glands fitted in the underside of the terminal box on
the rear of the display. Three identical glands are fitted and accept cables with an outside diameter
between 4.5mm and 7.0mm.
See connection drawing F-1835.

3.0 MAINTENANCE.
3.1 WIND SENSOR.
3.1.1 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.
3.1.2 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.
4.0 OPTIONS.
4.1 REMOTE INDICATOR CONTROL.
Special wind data displays are available for use in applications where remote control of the
illumination function is required. This display (ref: P271), available to special order, incorporates a 3
metre flying lead for connection to the separate remote indicator control (ref: P274). Connection
diagrams F-1836 and F-1685 apply in such instances. The remote indicator control is shown on
drawing 3047-2-1.
