RAWS-F Remote Automated Weather Station for Fire Weather
4.7.4 Calibration
For most applications, it is unnecessary to calibrate the CS516-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
If a problem is suspected, check the sensor cable. Disconnect the connector
and look for damaged pins. Verify the CS506 sensor element is securely
fastened. Try connecting a substitute sensor. Obtain an RMA number before
returning the CS516-QD sensor to Campbell Scientific for repair.

Troubleshooting
5.1 Solar Panels
5.1.1 General Description
The 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 the equator.
The SP10-QD 10 watt solar panel is recommended for a RAWS where NO
communication equipment is used. The SP20-QD 20 watt solar panel is
recommended for a RAWS where communication equipment is used (for
example, GOES, voice, cell phone, or radio).
The solar panel selected for the RAWS 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
The solar panel 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’s “CHG” and “CHG” ports. Polarity does not matter; either lead
can be connected to either terminal. The CH100 has two functions: blocking
any current flow from the battery to the solar panel, and limiting the source
current to the battery.
