3. OPERATING THE STATION
3.1. P
OWERING
The SV 271 LITE monitoring station can be powered from:
•
internal rechargeable battery,
•
external power supply (SB 270);
and optionally from:
•
external rechargeable battery (SB 272),
•
solar panel (SB 271).
When the power supply is connected, it starts powering the station and loading the
internal battery in parallel (as a voltage source).
When the external rechargeable battery is connected to the station the station
controller switches the powering from the internal battery to the external one. As soon
as the external battery is discharged the controller switches powering back to the
internal battery.
When the solar panel is connected to the station it starts to load the internal battery (as
a current source). And all the time that the solar panel charges the internal battery, the
station continues to be powered from the internal battery.
The status of powering is indicated at the controller’s panel by a combination of
DC ,
CHARGING , BAT 1 or BAT 2 LEDs (see Table below).
Note: It is recommended that the batteries of SV 271 LITE and SB 272 are
charged before going on site.
Note: Monitoring station and SB 272 have their own chargers, which are
incompatible: SB 270 is a waterproof power supply
for SV 271 LITE, whereas
SB 273 is an indoor charger for SB 272.
Note:
SVAN 971 is powered from the external source and doesn’t use its
internal batteries.
Internal instrument’s batteries must be removed for correct
system operation and safety reasons!
