If the TERENA is connected to the mains without
a battery, the "BAT ON" and "BAT CHECK" LEDs
are not lit up. If the TERENA is functioning on
battery power, the battery charge status is analyzed
(VHIGH = 14.4V, VLOW=11.5V and VCRITICAL = 10.2V)
in order to define what action needs to be taken.
1] When the battery charge level is above VHIGH :
- Data is backed up
- Battery monitoring is stopped, the "LOW BAT"
and "BAT ON" LEDs are not lit up.
2] If the battery charge level is between "VHIGH"
and "VLOW", the system functions normally.
The "LOW BAT" LED is not lit up and the "BAT ON"
LED is lit up. A verification procedure is carried
out every 2 minutes (the "BAT check" LED is lit up).
3] If the battery charge level is between "VLOW"
and "VCRITICAL", the battery is put on to charge.
The "LOW BAT" and "BAT ON" LEDs are lit up.
A verification procedure is carried out every
2 minutes (the "BAT check" LED is lit up).
4] If the battery charge level is below "VCRITICAL" :
- A back-up of the memory is done on the SD card,
- Battery monitoring is stopped, (the "LOW BAT"
LED is lit up and the "BAT ON" and "BAT CHECK"
LEDs are not lit up),
- The system comes to a complete halt if the
TERENA is not connected to the mains supply.
