RAWS-P Remote Automated Weather Station 1. Introduction The RAWS-P is the core of a permanent station. It consists of a CR1000 datalogger and 12 Vdc battery, housed and protected in an aluminum environmental enclosure. The sensors and the tripod/tower are purchased separately—allowing you to customize your station exactly the way you want it. Installation is easy because the selected sensors are attached to color-coded, keyed connectors on the outside of the RAWS-P enclosure (see FIGURE 1-1).
RAWS-P Remote Automated Weather Station Specifications are available from our web site at www.campbellsci.com. For “sensors specifications,” click on “Products”, select “Sensors” and go to the sensor manual for specifications. For “equipment specifications”, enter the part number in the “Search” box on the website mentioned above and go to the equipment manual for specifications. NOTE 2. Equipment and sensor specifications are provided on the ResourceDVD which ships with the RAWS.

Indicates CR1000 and TX320 are properly setup and running 21 SWR Standing Wave Ratio (SWR), only after a transmission. Indicates condition of antenna and cable. SWR should be less than 2.
RAWS-P Remote Automated Weather Station 3.3 Precipitation A rain gage should be located over an open level area covered by short grass, or where grass does not grow, the natural earth surface. Level the rain gage. NOTE 3.4 Take off the funnel and remove the rubber band securing the tipping bucket mechanism during transport. Solar Radiation A solar radiation sensor should be located to avoid shadows on the sensor at any time.
RAWS-P Remote Automated Weather Station 4.1.2 Wiring The HC2S3 attaches to the connector labeled TEMP/RH; this connector is color coded orange. This sensor is internally wired from the RAWS connector panel to the CR1000 datalogger. TABLE 4-1. TEMP/RH Connector (color coded orange) Connector Pin Description CR1000 Terminal A Temperature H 1L B Sensor Excitation VX1 C Sensor Signal L/ D Power Ground G E RH Signal 1H F Switched 12 V SW_12V 4.1.
RAWS-P Remote Automated Weather Station 4.2.3 Troubleshooting If a problem is suspected, check the sensor cable. Disconnect the connector and use a digital volt meter (DVM) to check the resistance between Pin A (sensor signal) and Pin C (sensor ground). The resistance should read as an open circuit until you move the rain gage tipping mechanism where the magnet swings past the reed relay. Try connecting a substitute sensor.
RAWS-P Remote Automated Weather Station NOTE 4.4 Consult the CS300-L manual for more information. Wind Speed and Direction 4.4.1 Wind Sensor 4.4.1.1 General Description The Met One Wind Sensor (pn 034B-LQ) is an integrated cup anemometer and wind vane. The anemometer consists of three cups that sense the wind speed. These cups rotate on a vertical shaft that magnetically activates a sealed reed switch. The reed switch opens and closes at a rate proportional to wind speed.
RAWS-P Remote Automated Weather Station 4.4.2 2-D WindSonic 4.4.2.1 General Description The Gill Instruments 2-D Sonic Wind Sensor (pn WindSonic4-LQ) is an ultrasonic anemometer for measuring wind direction and wind speed. It uses two pairs of orthogonally oriented transducers to sense the horizontal wind. The transducers bounce the ultrasonic signal from a hood, minimizing the effects of transducer shadowing and flow distortion.
RAWS-P Remote Automated Weather Station 4.5.2 Wiring The CS100 is mounted inside the RAWS environmental enclosure and the sensor wires are attached to the CR1000 printed circuit board wiring panel. TABLE 4-6. CS100-QD Wiring CS100 Wire Color CR1000 Terminal Blue 5L Yellow CAUTION Red 12V Clear G Black G Green C4 The CS100 is sensitive to static when the back plate is removed. To avoid damage, take adequate anti-static measures when handling this sensor. 4.5.

The CS205 mounts on the mounting stake with the CS506. 4.6.2 Wiring The CS516-LQ has one connector that attaches to the RAWS connector labeled FM/FT. The FM/FT connector is color coded brown. This sensor is internally wired from the RAWS connector panel to the CR1000. TABLE 4-7.
RAWS-P Remote Automated Weather Station NOTE The solar panel selected for the RAWS depends on the station power requirements, specifically the communication equipment selected for the station. The SP10-LQ solar panel outputs 0.59 Amps, 8.9 Watts typical peak power. The SP20-LQ solar panel outputs 1.17 Amps, 18 Watts typical peak power. 5.1.2 Wiring The solar panel attaches to the connector panel labeled “BATT CHARGER/SOLAR PANEL”.
RAWS-P Remote Automated Weather Station FIGURE 5-1. 12 volt charger/regulator 5.2.2 Wiring The leads from the RAWS connector panel “BATT CHARGER/SOLAR PANEL” connector COLOR CODED PURPLE are wired to the CH100 “CHG” terminals. Polarity does not matter; either lead can be connected to either terminal. The charge indicating diode should be “ON” when voltage to the charging circuitry (CHG Terminals) is present.
RAWS-P Remote Automated Weather Station 5.2.3 Troubleshooting If a problem is suspected, the CH100 may be checked by measuring: • • • input voltage between the two CHG terminals. From a solar panel, the voltage should be 15 to 28 Vdc. From the standard wall charger (pn 29796), the voltage should be 24 Vdc. charging output voltage (BATT INT or EXT terminal) with battery disconnected about 13.
RAWS-P Remote Automated Weather Station 5.3.3 Troubleshooting If a problem is suspected, measure the +12 V and Ground terminal on the CR1000 printed circuit board wiring panel. Acceptable readings are +11 to +14 Vdc. Use PC200W software to collect the 1-HR data table from the CR1000 and review the historical record of battery voltage. 5.4 GOES Transmitter 5.4.

RAWS-P Remote Automated Weather Station 5.4.3 Troubleshooting If a problem is suspected, the TX320 may be checked by measuring the +12 V and Ground terminal on the CR1000 PC-board wiring panel. Acceptable readings are +11 to +14 Vdc. Check the SC12 cable connection between the CR1000 wiring panel and the TX320. Press the TX320 diagnostic button to query the state of the transmitter. If problems persist, try a substitute.
RAWS-P Remote Automated Weather Station 5.5.2 Wiring The CR1000 Keyboard/Display (pn CR1000KD) connects to the CR1000 PC board “CSI/O” 9-Pin connector using a standard serial cable (pn 10873) that ships with the RAWS. 5.5.3 Troubleshooting If a problem with the CR1000 Keyboard/Display is suspected, the CR1000KD may be checked by connecting the CR1000KD to the CR1000 PC board 9-Pin “CS I/O” connector using our 9-pin serial cable (pn 10873). The CR1000KD display should be visible.

RAWS-P Remote Automated Weather Station performance testing (for example, bearing torque), and sensor component replacement, generally requires sending the instrument to Campbell Scientific. A station log should be maintained for each weather station that includes equipment model and serial numbers and maintenance that was performed. 8. NOTE Consult the equipment manual for routine maintenance procedures.
RAWS-P Remote Automated Weather Station in FIGURE 9-3. Note that when a negative number is subtracted from a positive number, the resulting arithmetic operation is addition. For example, the declination for Longmont, CO is 10.1°, thus True North is 360° ─ 10.1°, or 349.9° as read on a compass. Likewise, the declination for Mc Henry, IL is ─2.6°, and True North is 0° ─ (─2.6°), or 2.6° as read on a compass. FIGURE 9-1.
RAWS-P Remote Automated Weather Station FIGURE 9-2. A declination angle east of True North (positive) is subtracted from 360 (0) degrees to find True North FIGURE 9-3.
RAWS-P Remote Automated Weather Station 9.2 USGS Web Calculator The USGS provides an easy way of determining the declination of a specific site. Since magnetic declination fluctuates with time, it should be adjusted each time the wind sensor orientation is adjusted. The calculator can be accessed at: www.ngdc.noaa.gov/geomagmodels/Declination.jsp. FIGURE 9-4 shows an example for Logan, UT. FIGURE 9-4. USGS web calculator In the example above the declination for Logan, UT is 12º 24′ or 12.4º.
