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.
