RAWS-H Remote Automated Weather Station 1. Introduction The RAWS-H allows customers who own a Handar Data Collection Platform to upgrade to a Campbell Scientific Remote Automated Weather Station, while using the sensors and tower that they already own. The RAWS-H contains an aluminum 14- by 18-in. environmental enclosure, a CR1000M Module, a 12 Vdc sealed rechargeable battery, a CH100 regulator, a Handar sensor connector panel, a wiring panel, and a CR1000KD Keyboard Display.

Inside environmental enclosure (optional equipment shown) NOTE 2 Customized Handar sensor programming can be developed for a nominal fee.
RAWS-H Remote Automated Weather Station 2. Getting Started Set up and test your station before field deployment. NOTE Keep this manual and the CR1000KD Keyboard Display with the RAWS. Review the station siting and orientation section before field deployment. If a problem is encountered, review the equipment wiring and troubleshooting sections in this manual. After siting and leveling the RAWS, open the enclosure and (1) connect the battery cable and (2) verify the CH100 switch is in the ‘on’ position.
RAWS-H Remote Automated Weather Station • • 3.3 areas where snow drifts occur low places holding standing water after rains 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. 3.4 Solar Radiation A solar radiation sensor should be located to avoid shadows on the sensor at any time.

RAWS-H Remote Automated Weather Station The SP10-Handar 10 watt solar panel is recommended for a RAWS where NO communication equipment is used. The SP20-Handar 20 watt solar panel is recommended for a RAWS where communication equipment is used (for example, GOES, voice, cell phone, or radio). NOTE If the user supplies a solar panel for the RAWS, use an unregulated solar panel. The solar panel size depends on the station power requirements, specifically the communication equipment selected for the station.
RAWS-H 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-H 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-H Remote Automated Weather Station 5.4 GOES Transmitter 5.4.1 General Description The High Data Rate GOES transmitter (pn TX320) shown in FIGURE 5-2 supports one-way communication, via satellite, from a Campbell Scientific datalogger to a ground receiving station. Satellite telemetry offers a convenient communication alternative for field stations where phone systems or RF systems are impractical or rendered unreliable after a tragedy to the local infrastructure.
RAWS-H Remote Automated Weather Station FIGURE 5-2. GOES transmitter 5.4.2 Wiring The TX320 is mounted inside the RAWS environmental enclosure and the transmitter connections are described below. TABLE 5-1.
RAWS-H 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. 5.5 CR1000 Keyboard/Display 5.5.
RAWS-H Remote Automated Weather Station 5.5.2 Wiring The CR1000KD connects to the CR1000’s CS I/O connector using the 10873 cable that ships with the RAWS-H. 5.5.3 Troubleshooting If a problem is suspected, the CR1000KD may be checked by connecting the CR1000KD to the CR1000 PC board 9-Pin “CS I/O” connector using the 9-pin serial cable (pn 10873). The CR1000KD display should be visible. Check the CH100’s ON/OFF switch. If the display is not visible, check the CR1000 wiring panel for 12 volt power.
RAWS-H Remote Automated Weather Station 5.6.2 Wiring The CR1000 is mounted inside the RAWS environmental enclosure and fastened to the CR1000 printed circuit board wiring panel; connect 12 V power to the CR1000 printed circuit board wiring panel green power connector. The CH100’s ON-OFF switch applies power to the 12 V terminals. 5.6.

RAWS-H 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-H 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-H 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.
