3 OPERATING THE STATION
3.1 P
OWERING
The SV 258 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 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 258 PRO and SB 272 are charged before going
on site.
Note: The monitoring station and the external battery have their own chargers, which are
incompatible: SB 270 is a waterproof power supply
for SV 258 PRO, whereas SB 273 is an indoor
charger for SB 272.
Note: SVAN 958A
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!

ONTROLLER 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 958A connection state,
•
3G
– 3G modem connection state,
•
EXT I/O
– reserved.
Colour of LEDs can be red, orange or green. Colour of the
SVAN
and
3G
LEDs reflect the communication state
with the corresponding unit. Colour of the
DC
,
CHARGING
,
BAT 1
or
BAT 2
LEDs depend on the state of the
power supply and charging of the internal battery.
The table below shows combinations of LED colours in the specific power supply conditions.
