Controller
The SV 277 PRO monitoring station is equipped with
the
SD 270A PRO
(or
previous
modification
SD 270 PRO
without
the
TEST
button
and
corresponded LED) controller that integrates and
controls all system modules and is responsible for the
powering of all elements and communication between
the following elements of the monitoring station:
•
SVAN 977 instrument,
•
mobile modem
and optionally
•
meteo module, alarm lamp etc.
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 the
SB 270 power supply or optional solar panel or external battery).
Another key task of the controller is the integration of the entire system
– examining the
communication, 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 or remotely using
the mobile 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 allows you to reset the controller settings.
To do this, press and hold the TEST key for more than 20 seconds until the corresponding
LED lights up. Release the key and the controller will be reset.
The mini USB connector on the front panel of the controller is intended for updating the
controller firmware.
Note:
The mini USB connector 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 the SVAN 977 (USB socket).
Note: Communication of the controller or SVAN 977 with a PC requires
installation of the USB drivers on your PC. USB driver for Svantek devices
are available on
