6. INSTALLATION
Do NOT remove the black “rubber” transducer caps. Warranty is void if the
blue security seal is damaged or removed.
All the time the WindObserver II (Pipe Mount) is not in its final location, it
should be protected from damage by keeping it in the original packaging as
long as possible, treating it as a delicate instrument.
If an Intrinsically Safe (IS) device is required, the I.S. WindObserver must be
used - the WindObserver II (Pipe Mount) is NOT an IS device.
6.1. Installation Guidelines
The WindObserver II (Pipe Mount) has been designed to meet and exceed the stringent
standards listed in its specification. Operating in diverse environments all over the world,
WindObserver II (Pipe Mount) requires no calibration or adjustment whatsoever.
As with any sophisticated electronics, good engineering practice should be followed to
ensure correct operation.
Always check the installation to ensure the WindObserver II (Pipe Mount) 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 –
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 round)
are suggested
 VHF IMM – 1m
 MF/HF – 5m
 Satcom – 5m (avoid likely lines of sight)
Ensure the product is correctly earthed in accordance with this manual
Use cables recommended by Gill, keeping the length below the maximum allowed
(See Section 6.3) Where the cables are cut and re-connected (junction boxes, plugs
and sockets) the cable screen integrity must be maintained, to prevent the EMC
performance being compromised.
Earth loops should not be created – earth the system in accordance with the
installation guidelines. (See Section 6.4)
Ensure the power supply operates to the WindObserver II (Pipe Mount)
specification at all times.
Avoid turbulence caused by surrounding structures that will affect the accuracy of the
WindObserver II (Pipe Mount) 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.

6.2. Bench system test
Note: Prior to physically mounting the WindObserver II (Pipe Mount) 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. If an
Integrity Check Chamber (ICC) has been purchased refer to Section 10.6.
6.3. Cabling
Cable type
A RS422 compatible cable should be used, with the number of twisted pairs matching the
application.
Generic description
No. of pairs Gill ref. Belden
ref. Batt Electronics
6 026-03508 9806 91021
Cable length
The typical maximum length at 9600 baud is 1km using the recommended cable. If any
problems of data corruption are experienced (due to, for example, a high local electrical
‘noise’ level), then a lower baud rate should be used. Alternatively, a thicker or higher
specification cable can be tried. . If a heated unit is used on longer cables than supplied,
consideration should be given to powering the heater using lower gauge wire or
paralleling wires to reduce volt drops.
Cabling and junction box
The WindObserver II (Pipe Mount) unit is fitted with a flying 6 pair cable attached (4
metre long). This must be terminated in a suitable manner to prevent moisture ingress.
If any cable is likely to be exposed to mechanical damage, it must be enclosed in a suitable
conduit or cable tray. The cable must be securely fixed with cable clamps or equivalent at
regular intervals such that the WindObserver cable gland does not support the cable
weight.
The gland area at the base of the WindObserver II (Pipe Mount) should not be directly
exposed to moisture, as whilst the gland is sealed when mated, the anemometer is vented
to air at the base to avoid pressure build up.

6.4. Connections
Important Do NOT join any of the cores of the cable together. Joining cores
could damage the unit permanently. Any cores not used should be isolated.
Do NOT connect the unit’s 0V, heating –ve or digital 0V to the screen or earth.
The screens of each pair are joined together inside the anemometer - these should be
joined to the cable screen(s) of any further cable run. Avoid long grounding loops. Digital
OV should be used in conjunction with RS422 TX RX lines in order to improve noise
immunity.

Earthing or grounding
To ensure correct operation, and for maximum protection against lightning, the
anemometer MUST be correctly earthed (grounded) via its mountings. Inadequate
Earthing 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 M8 base screw. The cable screens must be joined with any cable
screen continuing from the unit’s cable via a junction box. The primary earth for the
anemometer must be provided via the base screws and not via the cable screens. See Fig.2.

It is recommended that the WindObserver II (Pipe Mount) mounting pipe be manufactured
from stainless steel 316, to prevent possible galvanic corrosion.
Stainless steel 316 fixings (supplied) must be used.
6.6. Power supplies
All WindObserver II (Pipe Mount) units
Voltage 9 to 30v DC
Current 60mA max. 50mA average
Heating Voltage 22V to 30V (max) AC RMS or DC.
Current allow for 3A.
 The AC Supply must be isolated from Mains Supply.
 The heating module requires a separate power supply.
 Heater Cable length should be minimised to avoid cable volt drops and ensure
maximum voltage received at the Anemometer.
 Each transducer is heated independently and will be active when ambient
temperature drops below approximately +15ºC each transducer will de-activate
when +25ºC threshold is reached.
The WindObserver II has reverse polarity protection.

7 USING WITH THE GILL WINDDISPLAY
The WindObserver II is designed to link directly to the Gill WindDisplay unit to provide a
complete wind speed and direction system.
When coupled to a WindDisplay, the WindObserver II (Pipe Mount) can be used as
supplied,
however if a fault occurs, the WindDisplay may lock into the last valid reading. Re-
configuring the Wind Observer (Pipe Mount) to Fixed Field Output (O2) will ensure
that any fault is flagged on the WindDisplay.
After coupling to a WindDisplay, the Wind Speed units and the Averaging period can be
selected using the WindDisplay controls. See the WindDisplay User Manual.
Note that although the WindDisplay can display wind speed in various units, these are
calculated within the WindDisplay. The data coming to the WindDisplay must be in
metres/sec (the factory default output setting).
Figure 3 The WindDisplay
The WindDisplay has been designed to provide anemometer power (approximately 15V
@40mA).
Note the WindObserver II (Pipe Mount) de-icing heater will need a separate power supply.
(See Section 6.6).
NOTE: - If the WindDisplay is configured for NMEA mode then the WindObserver II
(Pipe Mount) must also be configured for NMEA mode and 4800-baud operation
(configuration settings M5 and B2).

8 MESSAGE FORMATS & OPTIONS
On first applying power to the WindObserver II (Pipe Mount), it will be in ‘Measurement
Mode’, and it will output wind measurement information in one of nine configurations as
described below.
Setting the output format, units, other parameters, options and the communication settings
are all carried out in the alternative ‘Configuration Mode’.
See Section 9 CONFIGURING for details of how this is done.
The factory default settings are shown here in bold, and for convenience some
‘Configuration codes’ (as used to set the configuration) are shown in blue boxes.
For example M3.
8.1. Wind Speed format
The wind speed measurements can be output in one of the following formats:
UV, Polar, Customer formats (NMEA and Tunnel).
8.2. Output formats
The UV and Polar wind speed parameters are output in either ASCII or binary.
These parameters can be transmitted continuously or polled from the user.
Polar is also available in continuous NMEA format.
Output format Output Tri-state o/p Configuration code
Continuous No M1
ASCII UV Polled Yes M3
Continuous No M2
ASCII Polar Polled Yes M4
Binary UV Continuous No M7
Binary Polar Continuous No M8
Binary Tunnel Continuous No M6
NMEA Continuous No M5
Low wind speeds
Whilst the wind speed is below 0.05 metres/sec, the wind direction will not be calculated,
in CSV mode no wind direction figure is shown, in Fixed Field mode the last known good
direction figure is shown. All other output parameters will continue to update at the output
rate.
8.3. Networking
Gill Proprietary Network
Each anemometer connected to the network MUST be given a unique Unit Identifier
(Letters A to Z), and set to a polled tri-state mode (UV or Polar) (M3 or M4).
In these modes the communications transmit line is tri-state unless the anemometer is
responding to a command.
