Monitoring Station SV 279 PRO

3. OPERATING THE STATION
3.1. Powering
The SV 279 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 to power the station and load 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 279 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 279 PRO,
whereas SB 273 is an indoor charger for SB 272.
Note: SVAN
979 is powered from the external source and doesn’t use its
internal batteries. Therefore, it is advisable to remove the internal batteries
from SVAN 979 for safety reasons.
3.2. Controller interface
The controller interface consists of several LEDs, which indicate the state of the station
elements or their connection with the controller:
•
DC
– external power supply connection state (AC/DC converter),
•
CHARGING
– charging state of the internal battery,
•
BAT 1
– internal battery state,
•
BAT 2
– additional external battery state,
•
SVAN
– SVAN 979 connection state,
•
3G
– 3G modem connection state.
