2.1.2. SD 270(A) LITE Controller
The SV 271 LITE monitoring station is equipped
with the SD 270 LITE (and later modification
SD 270A LITE) controller that integrates and
controls all system modules and is responsible for
the powering of all elements of the monitoring
station.
A very important task of the controller is power distribution - it provides appropriate DC
power to the SVAN 971, managing external power sources such as a power supply
SB 270 or optional solar panel or external battery.
The next key task of the controller is integration of the whole system
– examining the
state and condition of every module of the system and the immediate indication of all
problems on the control panel by means of several LEDs.
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
