7. Select any other sensors you have, then finish the remaining Short Cut

steps to complete the program. The remaining steps are outlined in Short

Cut Help, which is accessed by clicking on Help | Contents | Programming Steps.

8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the

PC to datalogger connection is active, you can click Finish in Short Cut and you will be prompted to send the program just created to the datalogger.

9. If the sensor is connected to the datalogger, as shown in the wiring

diagram in step 6, check the output of the sensor in the datalogger support software data display to make sure it is making reasonable measurements.

Wind speed is measured with a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an AC sine wave signal with frequency proportional to wind speed.

Vane position is transmitted by a 10 kΩ potentiometer. With a precision excitation voltage applied, the output voltage is proportional to wind direction.

The R.M. Young Instruction Manual includes additional information on the operating principles, installation, and maintenance of the sensor.

The wind monitors are manufactured by R.M. Young and cabled by Campbell Scientific for use with our dataloggers. Lead lengths for the wind monitors are specified when the sensors are ordered. TABLE 5-1 gives the recommended lead length for mounting the sensor at the top of the tripod/tower with a CM200-series crossarm.

CM106 CM110 CM115 CM120 UT10 UT20 UT30

13 ft 13 ft 19 ft 24 ft 13 ft 24 ft 34 ft

Maximum cable length is 1000 feet.

Do not use long lead lengths in electrically noisy environments.

The wind monitor’s cable can terminate in:

• Pigtails that connect directly to a Campbell Scientific datalogger

(option –PT).

• Connector that attaches to a prewired enclosure (option –PW). Refer

to www.campbellsci.com/prewired-enclosures for more information.

Wind Monitor Series

Locate wind sensors away from obstructions such as trees or buildings. Generally, there should be a horizontal distance of at least ten times the height of the obstruction between the Wind Monitor and the obstruction. If the sensors need to be mounted on a roof, the height of the sensors above the roof, should be at least 1.5 times the height of the building. See Section 10, References direction sensors.

Tools required:

(p. 15), for a list of references that discuss siting wind speed and

• 5/64 inch Allen wrench

• 1/2 inch open end wrench

• Compass and declination angle for the site (see Appendix C, Wind

Direction Sensor Orientation

• Small screw driver provided with datalogger

• UV resistant cable ties

• Small pair of diagonal-cutting pliers

• 6 to 10 inch torpedo level

(p. C-1))

Install the propeller to its shaft using the nut provided with the sensor.

The wind monitor mounts to a standard 1 inch IPS schedule 40 pipe (1.31 inch O.D.). A 12 inch long mounting pipe ships with the wind monitor for attaching the sensor to a CM200-series crossarm with the CM220 (FIGURE 7-1) or 1049 NU-RAIL® fitting (FIGURE 4-1 in QuickStart section). The 05103 can also be mounted to a CM110 series tripod mast with the CM216 Mast Mounting Kit (see FIGURE 7-2).

Mount the CM200-series crossarm to the tripod or tower. Orient the crossarm North-South, with the 1 inch NU-RAIL® or CM220 on the North end. Appendix C, Wind Direction Sensor Orientation information on determining true north using a compass and the magnetic declination for the site.

Secure the mounting pipe to the NU-RAIL® or CM220. Place the orientation ring, followed by the wind monitor on the mounting pipe. Orient the junction box to the south, and tighten the band clamps on the orientation ring and mounting post. Final sensor orientation is done after the datalogger has been programmed to measure wind direction as described in Appendix C, Wind Direction Sensor Orientation

Route the sensor cable along the underside of the crossarm to the tower/tripod mast, and to the instrument enclosure. Secure the sensor cable to the crossarm and mast using cable ties.

7.4 Programming

Short Cut is the best source for up-to-date datalogger programming code. Programming code is needed,

• when creating a program for a new datalogger installation

• when adding sensors to an existing datalogger program

If your data acquisition requirements are simple and you are connecting the sensor to a pulse port, you can probably create and maintain a datalogger program exclusively with Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program.

Short Cut cannot edit programs after they are imported and edited in CRBasic Editor.

A Short Cut tutorial is available in Section 4.2, Step 2 — Use SCWin Short Cut to Program Datalogger and Generate Wiring Diagram

(p. 3). If you wish to

Wind Monitor Series

TABLE 7-2. Wind Speed Multiplier

7.4.1 Wind Speed

import Short Cut code into CRBasic Editor to create or add to a customized program, follow the procedure in Appendix A, Importing Short Cut Code Into CRBasic Editor

(p. A-1). Programming basics for CRBasic dataloggers are

provided in the following sections. Complete program examples for select CRBasic dataloggers can be found in Appendix B, Example Programs

(p. B-1).

Programming basics and programming examples for Edlog dataloggers are provided at www.campbellsci.com\old-manuals.

For CRBasic dataloggers, wind speed is measured using the PulseCount() instruction. Syntax of the the PulseCount() instruction is:

PulseCount( Dest, Reps, PChan, PConfig, POption, Mult, Offset )

The PConfig parameter should be set to 1 (Low Level AC) and the POption parameter should be set to 1 (Frequency).

The expression for wind speed (U) is:

U = Mx + B

where

M = multiplier x = number of pulses per second (Hertz) B = offset

TABLE 7-2 lists the multipliers to obtain miles/hour or meters/second when the measurement instruction is configured to output Hz.

The helicoid propeller has a calibration that passes through zero, so the offset is zero (Gill, 1973; Baynton, 1976).

05103, 05103-45, or 05106 0.2192 0.0980

7.4.2 Wind Direction

The wind vane is coupled to a 10 kΩ potentiometer, which has a 5 degree

electrical dead band between 355 and 360 degrees. A 1 MΩ resistor between the signal and ground pulls the signal to 0 mV (0 degrees) when wind direction is in the dead band (between 355 and 360 degrees).

The CR200(X) datalogger uses the ExDelSE() instruction to measure wind direction. All other CRBasic dataloggers use the BRHalf() instruction.

band. To overcome this problem all program examples use a delay of 20 ms (20,000 μs) and set any negative wind direction values to 0.0: If WindDir < 0, then WindDir = 0.0.

The excitation voltage, range codes, and multipliers for the different datalogger types are listed in TABLE 7-3. Appendix D, Wind Direction Measurement Theory instruction.

7.4.3 Wind Vector Processing Instruction

The Wind Vector output is used to process and store mean wind speed, unit vector mean wind direction, and Standard Deviation of the wind direction (optional) using the measured wind speed and direction samples.

8. Sensor Maintenance

Every month do a visual/audio inspection of the anemometer at low wind speeds. Verify that the propeller and wind vane bearing rotate freely. Inspect the sensor for physical damage.

Replace the anemometer bearings when they become noisy, or the wind speed threshold increases above an acceptable level. The condition of the bearings can be checked with R.M. Young’s Propeller Torque Disc (pn 18310) as described in the R.M. Young manual (see www.youngusa.com/products/7/).

The potentiometer has a life expectancy of fifty million revolutions. As it becomes worn, the element can produce noisy signals or become non-linear. Replace the potentiometer when the noise or non-linearity becomes unacceptable. The condition of the vertical shaft (vane) bearings can be checked with R.M. Young’s Vane Torque Gauge (pn 18331).

NOTE

Often Campbell Scientific recommends factory replacement of the bearings and potentiometer. Refer to the Assistance page of this document for the procedure of acquiring a Returned Materials Authorization (RMA). Mechanically-adept users may choose to replace the bearings or potentiometer themselves. Instructions for replacing the bearings and potentiometer are given in R.M. Young’s manuals (www.youngusa.com/products/7/

9. Troubleshooting

9.1 Wind Direction

Symptom: NAN, –9999, or no change in direction

1. Check that the sensor is wired to the excitation and single-ended channel specified by the measurement instruction.

2. Verify that the excitation voltage and range code are correct for the datalogger type.

3. Disconnect the sensor from the datalogger and use an ohmmeter to check the potentiometer. Resistance should be about 10 kΩ between the blue

and white wires. The resistance between either the blue/green or white/green wires should vary between about 1 kΩ to 11 kΩ depending on

vane position. Resistance when the vane is in the 5 degree dead band should be about 1 MΩ.

Symptom: Incorrect wind direction

1. Verify that the excitation voltage, range code, multiplier and offset

2. Check orientation of sensor as described in Section 7, Installation

9.2 Wind Speed

Symptom: No wind speed

1. Check that the sensor is wired to the pulse channel specified by the pulse

2. Disconnect the sensor from the datalogger and use an ohmmeter to check

3. Verify that the configuration code, and multiplier and offset parameters

Symptom: Wind speed does not change

Appendix A. Importing Short Cut Code Into CRBasic Editor

This tutorial shows:

• How to import a Short Cut program into a program editor for

additional refinement

• How to import a wiring diagram from Short Cut into the comments of

a custom program

Short Cut creates the following files, which can be imported into CRBasic Editor. Assuming defaults were used when Short Cut was installed, these files

reside in the C:\campbellsci\SCWin folder:

• .DEF (wiring and memory usage information)

• .CR2 (CR200(X) datalogger code)

• .CR6 (CR6 datalogger code)

• .CR1 (CR1000 datalogger code)

• .CR8 (CR800 datalogger code)

• .CR3 (CR3000 datalogger code)

• .CR5 (CR5000 datalogger code)

Use the following procedure to import Short Cut code and wiring diagram into CRBasic Editor.

1. Create the Short Cut program following the procedure in Section 4, QuickStart

file name used when saving the Short Cut program.

2. Open CRBasic Editor.

3. Click File | Open. Assuming the default paths were used when Short Cut was installed, navigate to C:\CampbellSci\SCWin folder. The file of interest has the .CR2, .CR6, .CR1, .CR8, .CR3, or .CR5 extension. Select the file and click Open.

4. Immediately save the file in a folder different from C:\Campbellsci\SCWin, or save the file with a different file name.

Once the file is edited with CRBasic Editor, Short Cut can no longer be used to edit the datalogger program. Change the name of the program file or move it, or Short Cut may overwrite it next time it is used.

5. The program can now be edited, saved, and sent to the datalogger.

6. Import wiring information to the program by opening the associated .DEF file. Copy and paste the section beginning with heading “-Wiring for CRXXX–” into the CRBasic program, usually at the head of the file. After pasting, edit the information such that an apostrophe (') begins each line. This character instructs the datalogger compiler to ignore the line when compiling.

(p. 2). Finish the program and exit Short Cut. Make note of the

Appendix C. Wind Direction Sensor Orientation

C.1 Determining True North and Sensor Orientation

Orientation of the wind direction sensor is done after the datalogger has been programmed, and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination; where magnetic declination is the number of degrees between True North and Magnetic North. The preferred method to obtain the magnetic declination for a specific site is to use a computer service offered by NOAA at www.ngdc.noaa.gov/geomag. The magnetic declination can also be obtained from a map or local airport. A general map showing magnetic declination for the contiguous United States is shown in FIGURE C-1.

Declination angles east of True North are considered negative, and are subtracted from 360 degrees to get True North as shown FIGURE C-2 (0° and 360° are the same point on a compass). For example, the declination for

Logan, Utah is 11.78° East (11 August 2015). True North is 360° – 11.78°, or

348.22° as read on a compass. Declination angles west of True North are

considered positive, and are added to 0 degrees to get True North as shown in FIGURE C-3.

Orientation is most easily done with two people, one to aim and adjust the sensor, while the other observes the wind direction displayed by the datalogger.

1. Establish a reference point on the horizon for True North.

2. Sighting down the instrument center line, aim the nose cone, or

counterweight at True North. Display the input location or variable for wind direction using a laptop or keyboard display.

3. Loosen the U-bolt on the CM220 or the set screws on the NU-RAIL® that

secure the base of the sensor to the crossarm. While holding the vane position, slowly rotate the sensor base until the datalogger indicates 0 degrees. Tighten the set screws.
