matter; either lead can be connected to either terminal. The CH100

charger/regulator has two functions: 1) blocks any current flow from the

battery to the solar panel, and 2) limits the source current to the battery.

5.1.3 Troubleshooting, Solar Panel

If a problem with the solar panel is suspected, the solar panel may be checked

by measuring the voltage output from the solar panel. Check the voltage with a

voltmeter connected between the two leads going to the CH100

charger/regulator “CHG” “CHG” terminals located inside the environmental

enclosure (15 VDC to 28 VDC). There must be solar radiation incident on the

panel and there must be a load connected to the solar panel. The load can be

the datalogger, other equipment, or a 75 ohm resistor capable of dissipating

solar panel power between the two leads. No voltage output implies a bad

solar panel, regulator, or cable. The magnitude of the voltage output depends

on the incident solar radiation. Check the sensor cable. Disconnect the

connector and look for damaged pins.

5.2 Charger/Regulator

5.2.1 General Description, 12 V Charger/Regulator (part #CH100)

The 12 volt charger/regulator (part #CH100) is a charging regulator for 12 V

rechargeable batteries. The CH100 is connected to an external charging source

such as an unregulated solar panel (part # SP20-Handar or SP10-Handar) or a

wall charger (part #9591-Handar). The CH100 charger/regulator has two

functions: 1) blocks any current flow from the battery to the solar panel, and 2)

limits the source current to the battery.

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)
