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®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

Vega TP-11 / User Manual
Revision 12 of 12 October 2021
5
the "Active" mode. If all attempts fail, the device will continue to accumulate data and will
attempt to connect to the network every 6 hours.
Hold the start button pressed (min. 5 seconds) to switch the device from the "Active"
mode back to the "Storage" mode without turning off the power (battery or external).
The device forms the data packet with current state with a configurable period from 5
minutes to 24 hours. The packets stored in the device memory and transmitting during the
next communication session with the LoRaWAN®network.
Examples
If the data collection period is set to 24 hours the packet is formed at 00.00 on the
internal clock of the device
If the data collection period is 12 hours then at 00.00 and at 12.00, and so on.
Data collection period when measurements are out of specified current value range set
independently and may be equal from 5 minutes to 24 hours.
The adjustable data transfer period can be from 5 minutes to 24 hours. When
beginning of communication session, the device starts sending packets with readings from
the earliest packet. The time of data transmitting cannot be specified, it’s defined in random
way for every device in chosen period of transmission from the moment of connection to the
network.
Example
Transmission period is 30 minutes, and device was started at 16:40 by the internal
device clock. In random way the device calculate data transmitting time and set it at 16:41 in
the half-hour period from 16:40 to 17:10. Thus, packets from this device will transmit at 16:41,
at 17:11, at 17:41, at 18:11 and so on every 30 minutes by the internal device clock.
When measurements are out of specified current value range the communication
period still the same if parameter “Immediately send data when current is out of range” is not
active.
If that parameter is active and external power supplying, then the alarm message will
be forming and sending during 2 minutes after the moment of current value measurements
are out of specified range. If external power not supplying, then the converter will detect
exceeding the specified limits during the following data collection session according to the
schedule only, but the modem will send that data immediately too. Every following message,
which will form according to the data collection period, also will have sent immediately until
the current value measurements are back in range.
Current value range set in the “Vega LoRaWAN Configurator” application with
parameters “Current low threshold” and “Current high threshold”. Current threshold set in mA
multiplied by 100.

Vega TP-11 / User Manual
6 Revision 12 of 12 October 2021
Example
In the device settings the low threshold value is 200 and high – 2500. It means the low
threshold of current value is 2 mA and high is 25 mA.
The internal clock is set automatically when you connect to the device through USB,
also can be adjust via LoRaWAN®network.
FUNCTIONAL
Vega TP-11 converter can be either of class A or class C (LoRaWAN classification) and
has the following features:
Automatic change from A class to C class when powered from an external
power supply
ADR support (Adaptive Data Rate)
Sending of confirmed packets (configurable)

For connect an external sensor contacts CL+ и CL- are used. Connection scheme see
on the picture below.
To save the battery life of the converter, the 24 V supply voltage is not continuously
supplied. The 24 V voltage is applied to the 4-20 mA device a few seconds before the polling
is performed so that the sensor can turn on and set the current corresponding to the
measured parameter. This time, the so-called "startup time", is a configurable parameter from
the configurator and can be set from 1 to 60 seconds.
The outputs OUT_1 and OUT_2 operate on the principle of open-drain and can be
used to control external devices, such as electric cranes, lighting, sirens and so on. The load
capacity of each output is no more than 200 mA.
Permissible load for each digital output is 200 mА
To increase the load on the device outputs, it is necessary to use an external relay. The
relay connection scheme is shown below.

MOUNTING RECOMENDATIONS
To provide the stable radio between the gateway and the end device it is
recommended avoiding the device installation in the places which are barriers for the radio
signal getting through like a reinforced floors and walls, a basement, an underground facilities
and wells, a metal case etc.
The necessary stage for the network deploying including a big quantity of end devices
is a radio planning work with nature experiments.
For mounting you will need:
wire stripper;
laptop.
Step by step mounting be like:
1. Setting the devices and connecting them to the network are usually carried out in
the office (see Network Deployment Manual).
2. Determination of suitable places for mounting at the object with a network tester.
3. De-energizing the connected equipment, metering devices, etc.
4. Placement the wires in the cable gland. It must be remembered that the wires must
be united in one cable of circular cross-section with diameter of 5…6 mm.
Inside the cable gland there is a sealant ensuring compliance with the
declared Ingress Protection rating of the device case. When removing the
sealant, as well as when installing wires of a different diameter or cross-
section, device performance may deteriorate until failure due to moisture
entering the case
5. Connecting all necessary wires to the TP-11 contacts.
6. TP-11 converter can be powered from an external power source as well as from a
battery. For working with battery, it is necessary to connect it to battery connector

on the board. For working with external power source you should use the contacts
+VPWR and Ʇ.
7. When the power is connected at the first time the device automatically switches to
the “Active” mode and starts registration in the network. But if the device with
connected battery or an external power has been switched to the “Storage” mode
(by the pressing on the start button more than 5 sec) then you need to press the
button to start.
8. By the laptop make sure that the device successfully sends the data.
9. Assembling the device.
10. DIN-rail mounting or another available way to mount the device on the object.
Before connecting the device to the network, make sure that its
