1. Introduction

MetPak Base Station is a compact multi-sensor instrument that measures the most essential weather parameters. It also provides a data collection system that allows customers to add their own selection of sensors to meet local requirements. A Gill Instruments Ultrasonic Sensor can be used to measure wind speed and direction. Temperature and Humidity are measured and Dewpoint calculated using an industry standard probe housed in a naturally aspirated radiation shield. Barometric pressure is measured using an industry standard sensor.

The Wind Sensor can be chosen from a 2 axis WindSonic Option 2 (white), WindSonic M Heated, WindObserver 70 enhanced heated or a 3 axis WindMaster or WindMaster Pro.

The MetPak Base Station combines all the instrument data into a single combined data string. This may be configured for digital ASCII RS232/RS422/RS485 (2 wire point to point) and digital SDI-12 outputs.

The instrument uses a rugged mounting clamp that attaches to any vertical pipe up from 30mm to 58mm diameter.

The Base Station electrical Hub box comes with a pre-installed 10 Metre cable to connect to a Gill Wind Sensor. There is one cable gland allocated to provide entry for termination of other sensors and one cable gland for data/power cables.

A Heater Interface box (optional accessory) allows for termination of the Base Station 10 Metre cable to a heated Wind Sensor and Heater power supply.

1.1 Principle of Operation

1.1.1 Wind Speed and Direction Sensor

The MetPak Base Station can be used with Gill 2axis (WindSonic or WindObserver) or 3 axis (WindMaster or WindMaster Pro) wind speed and direction sensors. They are connected via the supplied RS422 10 Metre lead. The sensors measure the times taken for an ultrasonic pulse of sound to travel from the North transducer to the South transducer, and compares it with the time for a pulse to travel from S to N transducer. Likewise times are compared between West and East, and E and W transducer.

If, for example, a North wind is blowing, then the time taken for the pulse to travel from N to S will be faster than from S to N, whereas the W to E, and E to W times will be the same. The wind speed and direction can then be calculated from the differences in the times of flight on each axis. This calculation is independent of factors such as temperature.

1.1.2 Radiation Shield

The Multi-Plate Radiation Shield protects temperature and relative humidity sensors from error-producing solar radiation and precipitation. This shield relies on a combination of plate geometry, material and natural ventilation to provide effective shielding.

1.1.3 Temperature and Relative Humidity Sensor with Dewpoint Output

The Rotronic HygroClip module is a complete instrument, with integrated temperature compensation. Calibration data is maintained within the integrated electronics. It provides digital output signals for Relative Humidity, Temperature and Dewpoint to the MetPak Base Station Hub box.

Figure 2 Position of Temperature and Relative Humidity Probe in the Radiation Shield

1.1.4 Barometric Pressure

Barometric pressure output is provided by a solid-state device fitted on to the circuit board in the MetPak Base Station Hub box. Vent to atmosphere is via a Gortex filter which also protects the pressure sensor from the effects of wind and rain.

2. Installation

MetPak Base Station has been designed to meet and exceed the stringent standards listed in its specification (see Para 6.1).

2.1 Pre-Installation Checks

As with any sophisticated electronics, good engineering practice should be followed to ensure correct operation:

 Ensure the MetPak Base Station and Wind Sensor will not be affected by other

equipment operating locally, which may not conform to current standards, e.g. radio/radar transmitters, generators etc.

 Avoid mounting in the plane of any radar scanner – a vertical separation of at least

2m should be achieved.

 When installing MetPak Base Station and Wind Sensor near radio transmitting

antennas, ensure that the mounting position fulfills the following minimum separations (all round):

 VHF IMM – 1m  MF/HF – 5m  Satcom – 5m (avoid likely lines of sight)  Use cables recommended by Gill (see Para 2.2.3). 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.

 Avoid earth loops – wire the system in accordance with these installation

guidelines.

 Ensure that the power supply operates to the MetPak Base Station and Wind

Sensor specification (see Para 6.1) at all times.

 Avoid turbulence caused by surrounding structures that will affect the accuracy of

the sensors such as trees, masts and buildings. The WMO make the following recommendations. 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.

 Keep away from building exhaust vents, machinery and motors.

Remote Base Communication Cabling

MetPak Base Station has five communication connection options:

 USB (using the 1.8m Gill USB cable, Part No. 1723-10-051).  RS232  RS422  RS485 (two wire point to point).  SDI-12 (Not with 3 axis WindMaster and WindMaster pro connected)

MetPak Base Station has one external Sensor Input connection:

 Gill Wind Sensor via 10 Metre cable (RS422 connection)

It is important that the cable is appropriate for the chosen connection option. The following sections describe the recommended types and maximum lengths of cable in each case.

NOTE. A 15-metre, 6-pair cable (wires stripped at each end) suitable for RS232/RS422 or SDI-12 communication is available from Gill Instruments (Part No. 1723-10-053).

Cable Type

Wire type: 24AWG Wire size: 7x32 AWG. Cable outer diameter: 6-8mm (to match the hub box gland).

For RS422/485 operation the cable should contain twisted pairs screened to match the application.

The following table shows an example manufacturers’ reference; other manufacturers’ equivalents can be used.

Cabling (unused wires)

Any unused wires in the connecting cables should be connected to ground preferably at the user equipment end.

Cabling protection

The Cable should be secured:

 With cable clamps or equivalent at regular intervals such that the hub

box cable gland does not support the cable weight.

 Away from the mounting bolts to prevent chaffing of the cable.

NOTE. Install appropriate strain relief support to the cable. If possible, pass the cable through the mounting pole.

Earthing

To ensure correct operation and for maximum protection from lightning, a separate lightning rod system is recommended to protect the system.

You can also earth the MetPak Base Station through its mountings or by connecting a grounding cable (minimum of 6mm² copper wire) to a spare MetPak Base Station metalwork bolt hole. Clean off any paint that might prevent a good connection on the installation.

When you connect the communications cable ensure that the screen has a connection to the hub box case.

The Junction Box accessory and Heater Power Interface Box have a plastic case, hence ensure continuity of cable screens into and out of the boxes using the common earthing terminals provided in the boxes.

Routing Cables through the Hub Box Glands

NOTE: The MetPak Base Station Hub Box cable glands contain spring loaded metal leaves that are designed to make a ground contact with cables that have an overall braid screen. Care is therefore required when inserting and removing cables through the glands to prevent damage to the metal leaves.

MetPak Base Station User Manual © Gill Instruments Ltd Last Change Page 20 22 April, 2013

Position

It is the responsibility of the customer to ensure that the MetPak Base Station is mounted in a position clear of any structure, including the mounting post, which may obstruct the airflow or induce turbulence.

Orientation

Normally, the MetPak Base Station is mounted on a vertical pole, ensuring a horizontal Measuring Plane, (see Figure 10).

For indoor use the unit may be mounted with the Measurement Plane set to any required orientation.

Alignment

The MetPak Base Station Wind Sensor should be aligned to point to North, or any other reference direction – for example, the bow of a boat.

Note. It is usually simpler to work first with a compass at ground level and identify a suitable landmark and its bearing.

Figure 10 Mounting and Dimensions for MetPak Base Station

Interference

Always check the installation to ensure the MetPak Base Station and Wind sensor is not affected by other equipment operating locally, which may not conform to current standards, e.g. radio/radar transmitters, boat engines, generators etc.

See Para 2.1 for guideline details.

CAUTION. Do NOT mount the MetPak Base Station and Wind Sensor in close proximity to high-powered radar or radio transmitters. A site survey may be required if there is any doubt about the strength of external electrical noise.

 Polled mode

If the unit has been set to polled mode type ?Q (where Q is the unit node letter) to prompt one line of the data string. Note, allow 9.5 seconds after switching on the unit before sending a poll command.

When polled, allow 570 milli-seconds for the unit to respond with a line of data. If the MetPak Base Station detects a pressure/temperature/humidity sensor fault then allow 4 seconds for an error data output.

Operation

MetPak Base Station User Manual Last Change © Gill Instruments Ltd 22 April, 2013 Page 45

Enter SETUP MODE to check Ser. Number and Firmware Version

To enter the unit’s setup mode:

 If the unit is in continuous reporting mode, type *.  If the unit is in polled mode, type *Q (where Q is the unit node letter).

The MetPak Base Station unit stops reporting sensor measurements and reporting (if in continuous mode) and responds with the following message:

SETUP MODE (The unit is now ready to receive commands).

Returning to measurement mode

To exit from the setup mode and return to the reporting mode: Type Q and press Enter. The MetPak Base Station unit returns to measurement mode and begins reporting (if

set up for continuous mode).

Polling for Data

The MetPak Base Station unit must be set for Message Mode Poll using MetSet software (Comms Page).

A line of data will be output upon receipt of a ? followed by the Node ID (default Q). It is recommended not to use letters A to F as these characters can appear in the

checksum in the data string.

Notes:-

In Polled mode the Base Station MUST be allowed 9.5 seconds after switch on (plus Wind Sensor start up times if separately powered) to be operational before the ? and Node letter are used to enable polling or it will be missed.

When in polled mode, when data is requested allow 570 milli-seconds for the unit to respond with a line of data.

If the MetPak Base Station detects a pressure/temperature/humidity sensor fault then allow 4 seconds for an error data output.

Polled mode can only be used for point to point communications; it is not possible to network units on to a common bus (except in SDI-12 mode).

3.4.6 Safe Mode

Summary

The MetPak Base Station Safe Mode provides a means of recovering communication with the MetPak Base Station whatever configuration setting may have been made. For instance if the unit has been set for SDI-12 operation Safe Mode can be used to change the communication option back to RS232 or RS422.

Connection

Connect the MetPak Base Station for RS232 communication as detailed on Page 11, Figure 6.

Method

Note at this stage the MetPak Base Station supply to be switched off. Open a Terminal program e.g. Gill WIND Software

(http://www.gill.co.uk/main/software.html ) or Windows HyperTerminal

Note if using Gill Wind Software that the Tools features are not applicable. Open Gill Wind Software. Serial Port: Set the drop down menu to the required COM Port Connection. Click on the OK button. Baudrate: Set the drop down menu to 4800 Bauds. A blank Wind Terminal screen will be opened. Hold down the * key on the keypad. With the * key still held down, apply power to the MetPak Precipitation. This will result in placing the unit into SAFE MODE. Press Enter to start a new line (Ignore illegal command line).

Operation

To now change communication from SDI-12 to RS232. Type COMMS RS232 and press Enter. Type Q and press Enter to exit SAFE MODE. Data will now scroll on screen.

Note however for RS232 changes to take place the unit must be powered down and back up again.

Close the 4800 baud rate Wind or HyperTerminal Program. Power down the MetPak Base Station and re-apply power. Open a new Wind or HyperTerminal program at 19200 baud rate. RS232 data will now scroll on screen at the MetPak Base Station default 19200-

baud rate.

Troubleshooting

4.2 Servicing

In the event of failure, prior to returning to an authorised Gill distributor it is recommended that:

 All cables and connectors are checked for continuity, bad contact,

corrosion etc.

 A bench test is carried out as described in the next section.

Contact your supplier if a fault persists.

4.3 Bench Tests

Carry out a bench test as follows:

1. Connect the MetPak Base Station unit to the host PC and power supply, using a known working test cable.

2. Check that the unit is correctly configured by going into Set Up mode using MetSet.

3. Check for normal output data, and that the Status Code is OK – 00.

4. If the status code is other than 00, refer to Table 12 for a list of status (error) codes.

5. Use an office fan or similar to check that the unit is sensing wind, turning the Wind Sensor to simulate changing wind direction and to check that axes are functioning.

6. Check for output changes in temperature and relative humidity sensor (the fan will also cause small changes in these properties).

5. Maintenance

Wind Sensor

If there is any build-up of deposits on the 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. The unit must be allowed to defrost naturally after being exposed to snow or icy conditions, do NOT attempt to remove ice or snow with a tool.

There are no moving parts or user-serviceable parts requiring routine maintenance. Opening the unit or breaking the security seal will void the warranty and the

calibration.

UV Shield (RM Young Model 41003)

HygroClip for Temperature, Humidity and Dewpoint (Rotronic Model HC2-S3-GI)

For extreme environments such as maritime installations, chemical plants or other areas of high pollution or contamination, Gill highly recommend replacement of the temperature and humidity probe filter every 6 months to ensure proper performance. Corroded, discoloured or clogged dust filters should be replaced.

If the filter is not replaced it is very likely you will see elevated humidity levels with time and if this is allowed to develop for a longer period of time it can lead to permanent damage on the electronics of the temperature probe due to the very high moisture content and corrosive effect of the pollutant or salt.

Rotronic Temperature and Humidity filter replacement: The Rotronics polycarbonate dust filter screw-on cap is available from:-

Gill Instruments Part Number 1723-PK-025 (2 filters). Rotronic Part Number NSP-PCW-PE (1 filter).

If you need to replace the dust filter cap, carefully unscrew it and withdraw carefully avoiding contact with the Temperature and Humidity circuit board. When re-fitting the filter cap, ensure the circuit board connections are not bent.

Consideration should be given to an annual calibration check of the HygroClip sensor by the manufacturer.

If you are replacing the whole cartridge, unscrew the metal ferrule and return the probe to Rotronic for calibration. Refer to the Rotronic Website for more details:

http://www.rotronic-humidity.com/content/meta/kontakt.php

NOTE. If you return the sensor to a HygroClip supplier for exchange, please request that the return unit has the dewpoint feature enabled (HCS2-S3-GI).

Filter

Ferrule

Maintenance

Barometer (on Hub PCB)

The Barometer device is maintenance-free, however, if required observe the following with regard to the central Hub box screw cap Gore-Tex® filter.

Pressure Sensor Filter Replacement: There is a small venting filter for the pressure sensor of the MetPak Base Station

located on the 'Hub' box lid which ensures proper conditions are present in the MetPak Base Station 'hub' box for pressure measurements without allowing any moisture or other damaging pollutants into the box. This filter is made from Gore-

Tex

material and is designed to last a long time without replacement, however,

Gill do recommend that this filter is replaced every 24 months to ensure proper operation of the pressure sensor and to keep the electronics inside the 'hub' box dry.

If you do not replace the filter every 24 months you may start to see elevated or erroneous readings of the pressure sensor with time and this behaviour can be

corrected by replacement of the Gore-Tex® filter unit.

The Gore-Tex® filter kit is available from:Gill Instruments Part Number 1723-PK-024. To replace the filter, unscrew the 4 screws retaining the hub box lid. Remove the

existing Gore-Tex filter and M12 Nut. Fit and secure the new filter with the nut provided. Re-fit the 4 lid screws.

Should you be uncertain as to how often you should be replacing the filters for your application or if you wish to discuss this in more detail please contact Gill support and we will be able to provide a recommendation for you.

Returning the MetPak Base Station

If the unit has to be returned, it should be carefully packed in the original packaging and returned to your authorised Gill distributor, with a full description of the fault condition. An RMA number should be obtained from Gill Instruments first if returning directly to Gill Instruments.
