3. OPERATING THE STATION
3.1. P
OWERING
The SV 277 PRO monitoring station can be powered from:
•
internal rechargeable battery,
•
mains power source (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 charging 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 charging 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 277 PRO and SB 272 are
charged before going on site.
Note: Monitoring station and external battery have their own chargers, which are
incompatible: SB 270 is a waterproof power supply
for SV 277 PRO, whereas
SB 273 is an indoor charger for SB 272.
Note: SVAN 977
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!
