USING THE LOGBOX SE

There are various power supply options. Simple battery management (controlled charging and protection from deep

discharge) is provided.

For minimum power consumption there is the POWER input. It is connected directly before power stabilizer, without any

charging or battery management option. Only PWROUT output is enabled.

POWER input is used in systems where very small power consumption is expected and there is no charging source available

(neither wall adapter, nor solar panel). Jumper BATT MNG must be removed. In this scenario it is possible to use 6xAA

batteries with GPRS data transfer.

Alkaline AA batteries can be used but if the GSM modem is used it is advised to use properly charged NiMh rechargeable

batteries ≥2500mA. The LOGBOX SE does not charge the 6 batteries in the holder.

If there is mains power supply available, it is recommended to use the CHARGER input. The input voltage range is from

7Vdc to 13Vdc. In this configuration a 12V lead acid battery can be connected with power management. Jumper BAT MNG

must be inserted. If correct CHARGER input is connected the SOLAR blue LED will light, indicating battery charging.

Very similar input is for solar panels on input SOLAR. It has the same features as CHARGER input. Maximum current from

solar panel is approximately 1A. Jumper BAT MNG must be inserted. If a solar panel is connected SOLAR a constant blue

LED will indicate charging. Once the battery is full, it will only flash.

Battery management cares for deep discharge condition of the attached 12V lead acid battery. If the voltage drops below

approximately 10.5V the battery is disconnected.

BATOUT output is available for powering sensors that must be powered all of the time, like wind speed sensors, Kipp &

Zonen SMART sensors or rain gauges.

Overall system operation is as follows: if main switch is in OFF position, only the real time clock is running. Most of other

the tasks are disabled. The user can enter service mode and communicate with data logger using a USB service cable.

If main switch is in ON position, full functionality follows and measuring and logging is started, indicated by the flashing

red and green LEDs.
