RAWS-P Remote Automated Weather Station
4.3.3 Troubleshooting, Pyranometer (part #CS300-LQ)
Check the sensor cable. Disconnect the connector and use a DVM to check the
voltage between Pin A Solar Sensor (+) and Pin B Solar Sensor (-). The
voltage should be 0 to 200 mV for 0 to 1000 Wm
-2
radiation. No voltage
indicates a problem with either the photodiode or the shunt resistor, both of
which are potted in the sensor head and cannot be serviced. Try connecting a
substitute sensor. Obtain a Return Material Authorization (RMA) number
before returning this sensor to Campbell Scientific for repair.
Consult the CS300-L manual for more information.

4.4 Wind Speed and Direction
4.4.1 Windset (part #034B-LQ)
4.4.1.1 General Description, Windset (part #034B-LQ)
The Met One Windset (part #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.
The wind direction is sensed by a vane. The vane drives a 10 K Ohm
potentiometer. The wind speed sensor outputs a pulse. The wind direction
sensor outputs a voltage.
4.4.1.2 Wiring, Windset (part #034B-LQ)
The windset sensor is connected to the RAWS connector panel “WS/WD”
connector COLOR CODED RED. The wind speed probe is internally wired
from the RAWS connector panel to the CR1000 datalogger.
Connector Panel “WS/WD” connector COLOR CODED RED
Connector Pin A Sensor ground
to CR1000 AG
Connector Pin B Wind dir. Excitation to CR1000 Ex2
Connector Pin C Wind dir. Signal
to CR1000 2H
Connector Pin D Power ground
to CR1000 Ground
Connector Pin E +12V power
to CR1000 +12V
Connector Pin F Wind speed signal
to CR1000 P1
4.4.1.3 Troubleshooting, Windset (part #034B-LQ)
Check the sensor cable. Disconnect the connector and look for damaged pins.
Verify free movement of the cup anemometer and wind vane. Try connecting
a substitute sensor. Obtain a Return Material Authorization (RMA) number
before returning this sensor to Campbell Scientific for repair.
Consult the 034B-L manual for more information.
