1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
The device Vega TD-11 is designed for measurement atmosphere temperature (air and
non-aggressive gases) by the external thermistor and further transmitting of this data to the
LoRaWAN network.
Also, device can act as a security sensor and send extraordinary alarm message by the
triggering security input.
There is a function of temperature range control in the device. During device setting,
you may set allowed temperature low and high thresholds. When temperature measurements
are out of specified temperature range then extraordinary communication session appears.
Data collection periods when measurements in temperature range and out are set
independently.
Vega TD-11 may be used in systems where temperature control is required but its directly
measurement is difficult. For example, car engine temperatures control and temperature
control at the production rooms, stocks.
TD-11 is powered by a SAFT LS 17500 battery with capacity 3600 mAh.
The device is powered by a non-rechargeable lithium-thionyl chloride
(LiSOCl2) battery Attempts to charge the battery may result in fire
COMUNICATION AND DATA COLLECTION ALGORITHM
Vega TD-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 TD-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

Vega TD-11 / User Manual

Revision № 06 – 10 August 2021
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.
When switching to the "Storage" mode, all readings from the pulse inputs
accumulated in the device memory are reset
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 temperature 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 temperature range the communication period
still the same if parameter “Immediately send data when temperature is out of range” is not
active. If that parameter is active, then the alarm message will be formed and sent during 2
minutes after the moment of temperature measurements become out of specified range. Every
following message, which will form according to the data collection period, also will have sent
immediately until the temperature measurements are back in range.
The internal clock is set automatically when you connect to the device through USB, also
can be adjust via LoRaWAN® network.

CONTACTS DESCRIPTION
Temperature sensor has a two contact pairs. One pair (“Therm” and “Ʇ”contacts) is for
connect to external thermistor, another one is security input (“Drv” and “Sens” contacts).
Security input of the device can be used for connecting to circuits with the following
types of NO contacts:
reed switch;
mechanical pushbutton;
open-drain output.
Polarity effects only "open collector" circuits. Open drain output must be connected to
“Drv” contact and ground to “Sens”.
Security input can trigger on short, open or both cases. It is configured by the “Vega
LoRaWAN Configurator” application. Should the security input triggering, the device is activated
and sends an alarm message to the network.
When thermistor connecting you should to configure sending data parameters in “Vega
LoRaWAN Configurator” application.

MOUNTING RECOMENDATIONS
To provide the stable radio between the gateway and the end device 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:
cross-shaped screwdriver ;
awl;
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. Making holes in the silicone gasket for wires - strictly according to the number of
wires. It must be remembered that the wire must be of circular cross-section and no
more than 3 mm in diameter.
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 TD-11 contacts.
6. Device launching – switching to the “Active” mode and registration in the network.

7. By the laptop you can make sure that the device successfully sends the data.
8. Before assembling the device, it is necessary to reset the pulses accumulated during
testing and connection by switching the device to the "Storage" mode by pressing
the button for 5 seconds.
9. Start the device by pressing launch button.
10. Assembling the device.
