RAWS-F Remote Automated Weather Station for Fire Weather
4.7.4 Calibration, Fuel Moisture/Fuel Temperature (part #CS515-QD)
For most applications it is unnecessary to calibrate the CS515-QD Fuel
Moisture and Fuel Temperature Sensor. However, for those users that are
interested in calibrating this sensor, please contact a Campbell Scientific
Applications Engineer.
4.7.5 Troubleshooting, Fuel Moisture/Fuel Temperature (part #CS515-QD)
Check the sensor cable. Disconnect the connector and look for damaged pins.
Verify the CS505 sensor element is securely fastened. Try connecting a
substitute sensor. Obtain a Return Material Authorization (RMA) number
before returning the CS515-QD sensor to Campbell Scientific for repair.

5.1 Solar Panels (part #SP10/20-QD)
5.1.1 General Description, Solar Panel (part #SP10/20-QD)
The RAWS Solar Panel is a photovoltaic power source used for charging lead
acid batteries. The SP20-QD 20 watt solar panel is used for system
configurations that have higher-than-average power requirements. It is also
recommended for use at higher elevations and latitudes. The solar panel
should be mounted facing south if located in the northern hemisphere, or facing
north in the southern hemisphere.
The SP10-QD 10 watt solar panel is recommended for a RAWS Quick
Deployment Weather Station where NO communication equipment is used.
The SP20-QD 20 watt solar panel is recommended for a RAWS Quick
Deployment Weather Station where communication equipment is used (i.e.,
GOES, voice, cell phone, or radio).
The solar panel selected for the RAWS Quick Deployment
Weather Station depends on the station power requirements,
specifically the communication equipment selected for the
station.
NOTE
The SP10-QD solar panel outputs 0.59 Amps, 8.9 Watts typical peak power.
The SP20-QD solar panel outputs 1.17 Amps, 18 Watts typical peak power.
5.1.2 Wiring, Solar Panel (part #SP10/20-QD)
The RAWS-Solar Panel (part # SP20-QD or SP10-QD) attaches to the
connector panel labeled “BATT CHARGER/SOLAR PANEL”. Inside the
RAWS environmental enclosure the “BATT CHARGER/SOLAR PANEL”
connector pin A and pin B are wired to the CH100 charger/regulator “CHG”
and “CHG” ports. Polarity does not matter; either lead can be connected to
either terminal. The CH100 charger/regulator has two functions: 1) blocks any
current flow from the battery to the solar panel, and 2) limits the source current
to the battery.
