connectors. The battery red lead connects to the positive battery terminal and
the black lead connects to the negative terminal.
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
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.
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-
Handar) 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.
Power out (+12 terminals) is controlled by the CH100 ON-OFF
switch position.
5.3 Battery
5.3.1 General Description, Battery
NOTE
WARNING
The RAWS battery is a rechargeable 12 volt battery. The battery requires a
regulated charging source provided by the RAWS Charger/Regulator (part
#CH100) connected to an unregulated solar panel or a wall charger.
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.
5.3.2 Wiring, Battery
The RAWS rechargeable battery should be connected to the CH100
charger/regulator 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
charger/regulator EXT (External) connector. It is possible to leave two
