Revision 26 of 25 August 2021
1 DEVICE PURPOSE AND OPERATION PRINCIPAL
DEVICE PURPOSE
Vega SI-11 pulse counter is designed for counting of pulses incoming to 4 independent
inputs, further accumulating and transmitting of this information to the LoRaWAN
®
network.
In addition, Vega SI-11 can be used as a security device - anyone of four inputs can be
configured as security input.
The pulse counter can be used for any utilities’ meters and industrial equipment with
pulse output of herkon type or open-drain type.
Equipment with NAMUR pulse output is not supported
The counter is powered by a SAFT LS 17500 battery with capacity 3600 mAh.
The device is powered by a non-rechargeable lithium-thionyl chloride
(LiSOCl
2
) battery
Attempts to charge the battery may result in fire
OPERATION ALGORITHM
Vega SI-11 operates in modes listed below:
“Storage” – is a mode for storing and transporting. In this mode the device does not
communicate regularly with the network.
“Active” – is a main mode of device operation.
Before start using you need to switch the device out of “Storage” mode.
Vega SI-11 supports two activation methods in the LoRaWAN
®
network - ABP and OTAA.
Select one of the methods via the “Vega LoRaWAN Configurator” application (see “User Manual”
on the program).
ABP method. After pressing the start button, the device immediately starts working in the
"Active" mode.
OTAA method. After pressing the start button, the device makes three attempts to
connect to the network within the set frequency plan. After the activation in the LoRaWAN
®
network is confirmed, the device sends a signal (LED flashing for 5 seconds) and switches to
the "Active" mode. If all attempts fail, the counter will continue to accumulate data and will
attempt to connect to the network every 6 hours.
