1 DEVICE PURPOSE AND OPERATION PRINCIPAL
DEVICE PURPOSE
The device Vega TP-11 is designed for reading of values from devices via 4-20 mA
current loop interface and further accumulating and transmitting of this data to the
LoRaWAN
network.
®
Converter can be used for sensors and industrial equipment with 4-20 mA interface,
temperature sensors, waste sensors, pressure sensors.
The converter is powered by a 6400 mAh battery. The converter can be powered by
the 10...36 V external power supply.
There is a function of current value range control in the device. During device setting
while external power supplying, you may set allowed current value low and high thresholds.
When current value measurements are out of specified range then extraordinary
communication session appears. Data collection periods are set independently when
measurements are in and out of specified range.
Converter is an autonomic device and provides connected sensors with 24 V power via
4-20 mA interface.
Vega TP-11 has two 'open-drain' outputs so it can be used as a control device. Also,
device has two security inputs.
OPERATION ALGORITHM
Vega TP-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-22 supports two activation methods in the LoRaWAN
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
