2PRESENTATION
Telik Trafo Lite is an IoT device for temperature monitoring in transformers. It is easy to install, with magnetic fastening, attached to the transformer
in a non-invasive way. Besides being compact and robust, it was developed with extremely low power consumption techniques and is powered by
two non-rechargeable batteries that have a useful lifespan of 5 to 10 years (depending on the configuration applied and the signal quality).
With easy network commissioning, Telik Trafo Lite has LoRaWAN communication to send data such as battery temperatures and voltage to online
dashboards. This data helps to monitor the behavior of transformers in a faster and more efficient way, identify overloads and, since the highest
failure rate in transformers is caused by overloading, reduce losses, and prevent unnecessary expenses.
Telik Trafo Lite is a class A End Device within the LoRaWAN architecture.

3.1 OVERVIEW
The device housing is made of Polycarbonate, a material with V0 flame retardant and UVA/UVB protection, and has been designed to meet IP66
protection. This allows Telik Trafo Lite to be exposed to the weather.
The sealing system has a silicone seal between the cover and the base of the housing.
The front cover has a hole for the installation head (purchased separately), used on the operating pole (see INSTALLATION HEAD section).
Figure 2 –Overview
The bottom of the housing has a Power key and an operation LED (see POWER KEY AND OPERATION LED section), which allow you to turn the
device on or off and obtain information about its status and connection:
Figure 3 –Bottom
On the back, built into the housing, are two neodymium magnets, which ensure the magnetic attachment of the device to the metal housing of the
transformer. Next to one of these magnets is the temperature sensor, which, in contact with the transformer, transmits the temperature signal to the
device:

3.2 IDENTIFICATION
The identification label, located on the back of the Telik Trafo Lite housing, contains its model, serial number and DevEUI. This data, along with
"JoinEUI" and "AppKey", is required to register the device on the Network Server. For security reasons, only the DevEUI is shown on the label.
This information come preloaded from the factory with the default used by the NOVUS connectivity plan (see NOVUS CONNECTIVITY PLAN section).
If needed to use the device with another Network Server, you can change "JoinEUI" and "AppKey" parameters.
To register the device in NOVUS Cloud with the NOVUS connectivity plan, you can use NXperience Mobile (see NXPERIENCE MOBILE section)
to get all the QR Code information. No need to open the housing.

4INSTALLATION
4.1 INSTALLATION
4.1.1 INSTALLATION RECOMMENDATIONS
If there is coverage for the LoRaWAN network in the location where the device will be installed, the device must be configured, i.e., it must be
registered in the application Network Server before performing the physical installation at the transformer. If the application used is NOVUS Cloud,
a NOVUS platform, you can register it through NXperience and NXperience Mobile (see CONFIGURATION SOFTWARE chapter).
When using another Network Server, you must follow the recommendations of the selected server. In this case, when using the USB interface of the
device, you can use NXperience to change the JoinEUI and AppKey values.
Once Telik Trafo Lite has been registered, simply turn it on using the Power key and wait for the status LED to indicate the three blinks code 3 (see
table in POWER KEY AND OPERATION LED section).
Once you are certain that the device has successfully connected to the LoRaWAN network, you can install the device at the transformer (see
TRANSFORMER INSTALLATION section).
If the device failed to successfully connect to the LoRaWAN network, follow the steps below:
1) Check that it has been correctly registered on the Network Server.
2) Check that there is good LoRaWAN coverage of the Network Server chosen for the region where the device is being installed.
3) If the Telik Trafo Lite fails to connect after 5 minutes, turn it off (see POWER KEY AND OPERATION LED section).
4) Find a higher position that allows you to better position the antenna.
5) Turn the device back on, with the antenna positioned upwards.
6) Wait up to 5 minutes to check if it was able to connect to the network.
4.1.2 POWER SUPPLY
The device is powered by two Lithium Thionyl Chloride (Li-SOCl2) batteries of size 14500 and 3.6 V. If you need to replace them, we recommend
using the batteries distributed by NOVUS.
To replace the batteries, you must remove the four screws from the back and then the front cover of the housing:
Figure 6 –Opening the housing
When replacing batteries, carefully observe their polarity:
Figure 7 –Replacing batteries
When closing the housing, please check the position of the silicone seal. Correct assembly ensures the original protection
rating.
Static sensitive material. Be sure to take necessary precautions before handling it.

NOVUS AUTOMATION 8/31
To complete the battery replacement process, you must use the Power key to inform the device that new batteries have been installed. To do this,
follow the steps below:
1) Ensure that the device is turned off. If it is on, you must turn it off.
To find out if the device is on, you can give a quick click on the Power key. If the LED lights up while the key is pressed, this means that the
device is on.
2) Press the Power key and keep it pressed until step 5.
3) Wait until the LED blinks quickly (approximately 2 seconds).
4) Wait until the LED blinks slowly (approximately 5 seconds).
5) Release the Power key.
6) This will restore the battery charge indicators.
7) After the procedure has been performed, the device will start up and renew the connection to the Network Server.
For information on estimated battery lifespan with respect to configuration, see BATTERY LIFESPAN section.
4.1.2.1 BATTERY LIFESPAN
Optimized lifespan is an important feature of battery powered LoRaWAN devices.
The Telik Trafo Lite batteries have a low discharge rate, aiming for 8 to 10 years of autonomy. Depending on the configuration of the device, this
period can be even longer.
The main factors influencing the battery lifespan are: Ambient temperature, transmission and sensor reading intervals, transmission power (TX Power)
and Spreading Factor (SF).
Based on different configurations, the table below gives an estimation of battery lifespan. As a reference, these values use an ambient temperature
between 20 and 25 °C (68 and 77 °F).

144 864 20 dBm 7 More than 10 years
144 864 20 dBm 12 Around 1.5 year
Table 1 –Battery lifespan
The data above are estimates and serve as a basis for an approximate range. By using a lower TX power, it is possible to extend these values.
The Spreading Factor (SF) impacts critical parameters: Range, transmission rate and transmission time. Changing the SF value will impact these
three variables, directly influencing the energy consumption. SF values range from 7 to 12. The closer you get to SF7, the lower the power
consumption; therefore, the closer to SF12, the higher the power consumption.
The environment temperature is another key factor that determines the lifespan and durability of batteries. Exceedingly elevated temperatures
increase the chemical reactions inside the battery and consequently the self-discharge. Extremely low temperatures reduce the battery ability to
produce energy.
BATTERY PASSIVATION
Passivation is a common occurrence in Li-SOCl2 batteries (used by Telik Trafo Lite). Storing the batteries for an extended period or extremely low
power consumption can form an insulating film inside the battery, which would restrict the current flow and cause a drop in the nominal voltage of the
battery. Despite this, passivation has a beneficial effect on Li-SOCl2 batteries as it reduces self-discharge. This allows them to be stored for extended
periods.
Passivation can be characterized by a drop in battery voltage during periods of consumption.
HOW TO IDENTIFY PROBLEMS WITH THE BATTERIES?
Telik Trafo Lite performs periodic readings of battery voltage and records the minimum, maximum, average, and instantaneous values. This data is
sent daily to NOVUS Cloud, where it can be accessed and analyzed.
When the voltage levels exceed the previously configured limits, an alarm message is sent, alerting about the battery status. This allows you to
identify problems such as battery discharge or passivation.

4.1.3 POWER KEY AND OPERATION LED
To turn on the device, simply press the Power key, located on the bottom of the housing, until the status LED starts operating. Through the following
blink codes, the LED informs the device status:
FLASHING TYPES
STATUS
Burst of fast flashing The system has been booted.
2 blinks The device is trying to connect.
3 blinks The connection was established.
Table 2 –Status LED
After being turned on for the first time, Telik Trafo Lite starts the connection process, where it automatically changes its parameters to achieve a
greater range and ensure low power consumption.
In the first stage of this process, the interval between connection attempts is 1 minute, while maximum transmission power and the best data
transmission rate are achieved. If the connection is not established in the first stage, the next attempts will occur successively in 10, 30, and 60
minutes.
In the last stage, the device keeps the power level and the Baud Rate static and sets the connection interval to 12 hours.
While trying to establish the connection, the status LED will only operate for the first 5 minutes.
After connection, the status LED will operate for only 1 minute. After this period, it will remain off.
To verify whether Telik Trafo Lite is on or off, give a quick click on the Power key. If the LED lights up while the key is pressed,
the device is on. Otherwise, the device is off.
To check the status of the device, you can give a short click on the Power key. This will activate the LED for a while longer. If the LED doesn't light
up, it means that the device is turned off.
To turn off the Telik Trafo Lite, you must press the Power key until the LED blinks quickly and continuously (for approximately 5 seconds). After that,
release the key. The device will go into stand-by mode, i.e., it will be inoperative until it is turned on again.

Figure 10 –Accessory installation
4.2.3 TRANSFORMER INSTALLATION
Before connecting the Telik Trafo Lite to the operating pole and installing the device in the transformer, you must ensure that it is registered on the
application server (see INSTALLATION RECOMMENDATIONS section). This registration is your own responsibility.
After following the steps explained in the INSTALLATION section, simply bring the device to the installation point. Since it uses magnets, it is
recommended that you keep it away from other metal parts during lifting to the installation point.
The installation of the device in a transformer must be carried out by a trained professional, respecting the safety protocols for handling the operating
pole.
