RAWS-P Remote Automated Weather Station
5.2.2 Wiring, 12 V Charger/Regulator (part #CH100)
The leads from the RAWS connector panel “BATT CHARGER/SOLAR
PANEL” connector COLOR CODED PURPLE are wired to the CH100
“CHG” terminals. Polarity does not matter; either lead can be connected to
either terminal. The charge indicating diode should be “ON” when voltage to
the charging circuitry (CHG Terminals) is present.
An internal and/or external battery can be connected to the CH100
Charger/Regulator by means of the INT (Internal) or EXT (External)
connectors. The battery red lead connects to the positive battery terminal and
the black lead connects to the negative terminal.
An “external battery cable” (part #6186) ships with the RAWS
Quick Deployment Weather Station. NOTE
Connect 12 V power to the datalogger and/or peripherals using the “+12
and Ground” terminals. The ON-OFF switch applies power to these 12 V
terminals.
Reversal of battery polarity will damage the CH100 or
battery.
WARNING
A battery must be attached for the CH100 to function
correctly as a power supply. CAUTION
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
5.2.3 Troubleshooting, 12 V Charger/Regulator (part #CH100)
If a problem with the charger/regulator (part #CH100) is suspected, the CH100
may be checked by measuring: 1) input voltage (CHG terminals) from the solar
panel (15 VDC to 28 VDC) or input voltage from the AC adapter (part #9591-
QD) about 18 VAC RMS, 2) charging output voltage (BATT INT or EXT
terminal) with battery disconnected about 13.5 VDC to 14 VDC, and 3) power
out (+12 terminals) about 11 VDC to 14 VDC. No voltage output implies a
bad solar panel, regulator, or battery. Power out (+12 terminals) is controlled
by the CH100 ON-OFF switch position. If problems persist, try a substitute.
Obtain a Return Material Authorization (RMA) number before returning this
equipment to Campbell Scientific for repair.
Power out (+12 terminals) is controlled by the CH100 ON-OFF
switch position. NOTE
Consult the CH100 manual for more information. NOTE
