RAWS-F Remote Automated Weather Station for Fire Weather
No voltage output implies a bad solar panel, regulator, or battery. If problems
persist, obtain an RMA number and return the device to Campbell Scientific
for repair.
Power out (+12 terminals) is controlled by the CH100 ON-OFF
switch position. NOTE
5.3 Battery
5.3.1 General Description
Two power supply options are offered for the RAWS-F. The ─24 option
includes a 24 A h sealed rechargeable battery, an external 20 W solar panel,
and a CH100 regulator. The ─7 option includes a 7 Ahr sealed rechargeable
battery, an external 10 W solar panel, and a CH100 regulator.
RAWS rechargeable batteries are designed to be float
charged. Permanent damage occurs and battery life is
shortened if the battery is allowed to discharge below
10.5 volts. WARNING
5.3.2 Wiring
The RAWS rechargeable battery should be connected to the CH100’s INT
(Internal) connector. The battery red lead connects to the positive battery
terminal and the black lead connects to the negative terminal. If desired, an
external battery can be connected to the CH100’s EXT (External) connector.
An “external battery cable” (pn 6186) ships with the RAWS-F.
Reversal of battery polarity will damage the CH100 or
battery. WARNING
It is possible to leave two batteries connected. The battery
connections are diode isolated; however, if one of the
batteries fails, it could draw all the charging current and the
other battery will be discharged. CAUTION
5.3.3 Maintenance
There are no user-serviceable parts on the battery. No maintenance is required.
5.3.4 Calibration
No calibration is required.
