A very important task of the controller is power distribution - it provides appropriate DC power to every element
of the system (managing external power sources such as a power supply SB 270 or an optional solar panel or
an external battery).
The next key task of the controller is integration of the whole system
– examining the communication, state and
condition of every module of the system and the immediate indication of all problems on its control panel by
means of several LEDs or remotely using 3G Internet connection.
The controller also analyses the temperature condition inside the monitoring station case. If the internal
temperature is higher than 50
o
C, the controller will switch off internal battery charging. If the temperature further
increases over 65
o
C, the controller will switch off the monitoring station. The station will be also switched off if
the internal temperature falls below -30
o
C.
The TEST key in the SD 270A PRO controller enables the controller resetting. To do this, press and hold the
TEST key more than 20 seconds until the LED lights up. Release the key and reset of the controller will be
done.
A mini USB connector positioned on the front panel of the controller is designated to the controller firmware
upgrade.
Note: The mini USB co
nnector on the controller panel doesn’t provide any measurement or setup
data exchange with the PC. Such data exchange is carried out via the USB Device 1.1 interface of
SVAN 958A (USB socket).
Note: Communication of the controller or SVAN 958A with a PC requires installation of the USB
drivers on your PC. USB drivers for Svantek devices are available on
Note: Before starting upgrading be sure that your + software is Off! If not, please Exit it
before starting any upgrading.

1. If you upgrade the firmware without removing the controller switch off SVAN 958A and wait until all
LEDs are off.
2. Connect the controller to the PC with the SC 56 cable. This operation opens a window which displays
the state of downloading the program. After successful loading the
“File loaded” will be displayed.
3. Press any key on the PC to finish firmware download.
4. Disconnect the SC 56 cable. The

upgrading, disconnect the SC 56 cable and repeat steps from 2 to 5.
Note: In the case of any problems with upgrade, switch off SVAN 958A and wait until all LEDs are
off, then extract the controller from the case and repeat steps from 2 to 5.
