1. FOREWORD

Thank you for purchasing a WindMaster or WindMaster Pro manufactured by Gill Instruments Ltd. The units have no customer serviceable parts and require no calibration or maintenance. To achieve optimum performance we recommend that you read the whole of this manual before proceeding with use.

Gill products are in continuous development and therefore specifications may be subject to change and design improvements without prior notice.

The information contained in this manual remains the property of Gill Instruments and should not be copied or reproduced for commercial gain.

2. INTRODUCTION

This manual describes the operation of the WindMaster (1590-PK-020/W, 1590-PK-050 Pipe Mount + options), 1590PK-130/W WindMaster RA (Right Angle Head) and WindMaster Pro (1561-PK-020/W + options).

The term 'WindMaster' is used in this manual as a general term for both the WindMaster and the WindMaster Pro; they are robust three axis anemometers, with no moving parts.

The units of wind speed, output rate, and formats are all user selectable. The WindMaster, constructed in aluminium and carbon fibre, can perform measurements in wind speeds up to 45 m/s. The WindMaster Pro, constructed from marine grade stainless steel 316, can perform measurements in wind speeds up

to 65 m/s. Options include up to four analogue input and four analogue output channels (12 or 14 bit resolution for WindMaster;

14 bit resolution for WindMaster Pro, W speed improvement and Sonic Temperature improvement. A PRT input is also available (WindMaster Pro only).

Units may additionally be calibrated in a wind tunnel to ISO 16622, traceable to national standards. WIND software is available free from the Gill website www.gillinstruments.com. It is strongly recommended as it

provides an easy, user-friendly interface to configure the unit. WINDVIEW software is available free from the Gill website www.gillinstruments.com. It provides a means of viewing

data and providing a simple data logging function.

3. PRINCIPLE OF OPERATION

Figure 1 Time of Flight details

The WindMaster measures the times taken for an ultrasonic pulse of sound to travel from an upper transducer to the opposite lower transducer, and compares it with the time for a pulse to travel from lower to upper transducer.

Likewise times are compared between each of the other upper and lower transducers. As Figure 1 shows, the air velocity along the axis between each pair of transducers can then be calculated from the

times of flight on each axis. This calculation is independent of factors such as temperature. From the three axis velocities, the wind speed is calculated, as either signed U, V, and W, or as Polar and W. It can be seen from Figure 1 that the speed of sound in air can be calculated from the times of flight. From this the sonic

temperature can be derived from the formula T

S1 = C1

/ 403

Where

S1 =

Sonic temperature

= Speed of sound Note the formula does not account for the effect of Humidity Crosswind correction is applied to results.

The wind speed in the UV plane, with direction in degrees from 0 to 359 , with respect to the Reference spar (which is normally aligned to North).

U, V, and W axes definition

+U is defined as towards the direction in line with the north spar as indicated in the diagram. +V is defined as towards the direction of 90 anti-clockwise from N / the Reference spar. +W is defined as vertically up the mounting shaft. Note, when the unit is configured for the X2 setting the UV definition rotates 30 degrees anti-clockwise such that U is

now in line with transducer axis 1.

Effects of temperature, barometric pressure, rainfall and humidity

The calculated u, v and w components are independent of temperature, pressure, rainfall & humidity within the operating parameters of the WindMaster.

The calculated sonic temperature/speed of sound should be corrected by the user for humidity to provide an indication of ambient temperature. The calculated Sonic Temperature/Speed of Sound is corrected internally for crosswind.

Measurement sequence

Syncpoll 1

In this mode when a Poll command is received it will trigger a single 50mS or 31.25mS ultrasonic measurement as illustrated in the table above and at the same time will trigger a Wind measurement output resultant from the previous polled measurement.

Notes:The minimum poll rate supported in this mode is 20Hz. Analogue inputs are not supported in Syncpoll mode 1.

Signal processing

Instantaneous Sampling

The WindMaster can be configured to output the sampled data direct at the selected output rate without any averaging "Instantaneous Sampling". Alternatively data can be sampled at 20Hz or 32Hz and averaged (see section 10.2 Fx y and Px). This applies for wind data and speed of sound. All samples are transmitted with a status code.

Retries Enabled

If this mode is selected, if a problem sample is detected, the unit will attempt another ultrasonic firing within the set time parameters.

Calibration Enabled /Disabled

The on-board calibration (providing compensation for spar and transducer shadowing), can be disabled, returning the unit to raw, uncorrected operation

Selection of the above parameters is via using Gill Wind software package or using a Terminal Program to set the FX or Px command.

5.5. Packaging

Whilst the WindMaster is being moved to its installation site, the unit should be kept in its packaging. All the packaging should be retained for use if the unit has to be returned at any time.

Note that if the WindMaster is to be regularly moved around, a travelling case is available as an optional extra.

5.6. Installation requirements

PC requirement

WIND and WINDVIEW software will operate with any PC with Windows software up to at least Windows 8

versions. The PC must be fitted with a suitable interface to match the chosen communication format - RS232, RS422, or

RS485 point to point. Alternatively a Gill Power Supply and Interface (PCI) may be used to convert RS422/485 output to RS232.

Other equipment

Analogue inputs / outputs must be compatible with the options fitted to the WindMaster or WindMaster Pro. See Sections 8 and 9.

Connection

o The WindMaster/Pro unit is fitted a 31 way Clipper industrial plastic socket and supplied with a modified

mating plug (shell size 3) with solder bucket pins (separate 31 way plug not needed/supplied with WindMaster part 1590-PK-020).

o The cable should be securely fixed with cable clamps or equivalent, so that the cable is not under stress at the

plug.

o There are restrictions on the maximum cable lengths for correct operation. See 6.4. o The cable should be routed up the inside of the mounting tube. o See 6.3 for cable specification.

Power supply

o The WindMaster requires a DC supply of between 9 – 30 V DC. o Typical current drain 55 mA @ 12 V (excluding analogue outputs). o Allow up to a further 80mA maximum if four 4-20mA analogue connections are used.

WindMaster and WindMaster Pro 1561-PS-0001. Issue 11 February 2017

________________________________________________________________________________________________________________________

6. INSTALLATION

6.1. Installation Guidelines

As with any sophisticated electronics, good engineering practice should be followed to ensure correct operation.  Always check the installation to ensure the WindMaster is not affected by other equipment operating locally,

which may not conform to current standards, e.g. radio/radar transmitters, boat engines, generators etc.

 Guidelines –

o Avoid mounting in the plane of any radar scanner – a vertical separation of at least 2m should be achieved. o Radio transmitting antennas, the following minimum separations (all round) are suggested.

 VHF IMM – 1m  MF/HF – 5m  Satcom – 5m (avoid likely lines of sight)

 Use cables recommended by Gill. If cables are cut and re-connected incorrectly (perhaps in a junction box) then

EMC performance may be compromised if cable screen integrity is not maintained.

 Earth loops should not be created – wire the system in accordance with the installation guidelines.  Ensure the power supply operates to the WindMaster specification at all times.  Avoid turbulence caused by surrounding structures that will affect the accuracy of the WindMaster such as trees,

masts and buildings.

 The World Meteorological Organisation makes the following recommendation:  The standard exposure of wind instruments over level open terrain is 10m above the ground. Open terrain is

defined as an area where the distance between the sensor and any obstruction is at least 10 times the height of the obstruction.

 If the sensor is to be mounted on a mast boom, part way up a tower or mast, then the boom should be at least twice

as long as the minimum diameter or diagonal of the tower. The boom should be positioned on the prevailing wind side of the tower.

 If mounted on a pole then as a guide the distance from an adjacent pole should be 10 times the other pole diameter.  If mounting on a building then as a guide the sensor should be mounted at a height of 1.5 times the height of the

building.



6.2. Bench system test

Note: Prior to physically mounting the WindMaster in its final location, we strongly recommend that a bench system test be carried out to confirm the system is configured correctly, is fully functional and electrically compatible with the selected host system and cabling (preferably utilising the final cable length). The required data format, units, output rate, and other options should also all be configured at this stage.

6.3. Cable type

An RS232 / RS422 compatible cable (as appropriate) should be used, with the number of twisted pairs matching the application.

Generic description – Twisted pairs with drain wire, screened with aluminised tape, with an overall PVC sheath. Typical Wire size 7/0.2mm (24 AWG), 22AWG wire may also be used.

Gill 15m lead - A nine pair, 22AWG, 15metre lead, with one end free and the other end fitted with Clipper pins, is available as an accessory from Gill, see 5.4 Accessories for part number.

6.4. Cable length

The maximum cable length is dependent on the chosen communication format (RS232, RS422 or RS485), the baud rate, and, to a lesser extent, on the cable type and the local electrical ‘noise’ level.

The above table shows the typical maximum lengths at the given baud rates, using the recommended cable. If any problems of data corruption etc. are experienced, then a slower baud rate should be used. Alternatively, a thicker or higher specification cable can be tried.

6.5. Grounding (Earthing)

To ensure correct operation, and for maximum protection against lightning, the anemometer MUST be correctly grounded (earthed) via its mountings. Inadequate grounding will degrade anemometer performance, particularly in the presence of radio frequency interference.

The unit MUST be connected to an appropriate grounding point with a minimum of 6mm² copper wire, via the M6 base screws. The primary earth for the anemometer must be provided via the base screws and not via the cable screens.

6.6. Connections

Important

 Do NOT join any of the cores of the cable together.  Any cores not used should be isolated.  Do NOT connect the unit’s analogue output 0V or power 0V to the screen or ground / earth.  The integrity of the screen of each pair should be maintained throughout the cable run.  Avoid long grounding loops.  For maximum lightning protection it is essential that the unit be properly grounded via its mounting base.

31 Way Connector Cable Assembly.

Open the pack of parts (1561-PK-050) provided with the WindMaster (not Pipe Mount units). Strip the cable and solder the contact pins to the cores (please note that the connector supplies the correct strain relief

for cables with an outside diameter of 6-12mm).

Put the parts on the cable in the order as shown below.

Whilst squeezing the red retainers in the direction of ARROW A, pull in the direction of ARROW B.

Your connector should now resemble the connector in the picture above.

Once all of the contacts are inserted push the red retainer into place. NB. The retainer can only be pushed back into place if the contacts are fully engaged. Fit the connector to the WindMaster so that you can now finish assembling the connector. Screw the back-shell onto the connector until it is fully in place. Please note that the final rotations can be slightly

stiff

Screw the cable clamp into the back shell

Now screw the cable-clamping nut into place

The connector can now be removed from the WindMaster.
