RAWS-P Remote Automated Weather Station
5.7.2 Wiring, CR1000 Datalogger (part #CR1000)
The CR1000 datalogger 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 ON-OFF switch applies power to the 12 V terminals.
5.7.3 Troubleshooting, CR1000 Datalogger (part #CR1000)
If a problem with the CR1000 datalogger is suspected, the CR1000 may be
checked by connecting the CR1000KD to the CR1000 printed circuit board 9-
Pin “CSI/O” connector using a standard RS-232 serial cable (part #10873).
The CR1000KD display should be visible. If the display is not visible, check
the CR1000 printed circuit board for 12 Volt power. If the CR1000 is
unresponsive to CR1000KD key strokes, then there might be a problem with
the CR1000 datalogger. If problems persist, try a substitute. Contact a
Campbell Scientific applications engineer for assistance. Obtain a Return
Material Authorization (RMA) number before returning this equipment to
Campbell Scientific for repair.
Consult the CR1000 manual for more information.
NOTE
6. Desiccant
6.1 When to Replace Desiccant
A humidity indicator card and desiccant packs are provided with the weather
station. Place the humidity indicator card and 2 ea. desiccant packs inside the
enclosure. Desiccant packets inside the enclosure should be replaced with
fresh packets when the upper dot on the indicator begins to turn pink. The
indicator tab does not need to be replaced unless the colored circles overrun. A
humidity indicator card (part #6571) and desiccant pack (part # 4905) may be
ordered through Campbell Scientific. Desiccant packs inside of the datalogger
do not require replacement under normal conditions.
6.2 Reusing Desiccant
Customers can reactivate saturated desiccant packets. Care must be taken. If
the heating process is too rapid, water vapor is released too quickly causing too
much pressure to build up inside the packets so that the packets burst.
Standard Oven Method:
1.
Bake at an oven temperature of 125ºF for 2 hours.
2.
Increase the oven temperature to 175ºF and bake for 2 hours.
3.
Increase the oven temperature to 245ºF to 250ºF and bake for 12 hours.
The optimum situation for reactivation is to use a recalculating oven that has a
ramping temperature. The desiccant should bake for 16 hours, and the final
temperature should be 245ºF to 250ºF.
