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.

3IDENTIFICATION
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:
Figure 4 –Back

NOVUS AUTOMATION 6/31
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.
Figure 5 –Identification label

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.

NOVUS AUTOMATION 9/31
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.
4.2 MECHANICAL INSTALLATION
4.2.1 DIMENSIONS
Telik Trafo Lite has the following dimensions:

Figure 9 –Installation head

NOVUS AUTOMATION 10/31
Once the installation head is attached to the operating pole and attached to the front of the Telik Trafo Lite, you can install it in the transformer:
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.

5COMMUNICATION INTERFACES
5.1 USB INTERFACE
Telik Trafo Lite has a USB interface, located inside the housing:
Figure 12 –USB Interface
To access it, you must remove the four screws from the back of the housing and remove the front cover.
You can use the USB interface to update firmware, configure and perform diagnostics on the device using the NXperience software (see
CONFIGURATION SOFTWAREchapter). To connect your Telik Trafo Lite to a computer, use a micro-USB cable (not supplied).
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.
5.2 LORAWAN INTERFACE
LoRaWAN is the protocol that defines the parameters and architecture of the data communication system over LoRa technology. It is compatible with
the following operating bands: LA915 (Brazil) and AU915 (other countries) The protocol also defines security features, data traffic rules, quality of
service, and power settings to maximize the correlation between signal quality and battery lifespan. It is a type of technology that allows low data
traffic.
A LoRaWAN system contains four main elements:
1) Devices: Also called "End Devices", these are the devices that produce data, that is, that perform data acquisition and/or operate on the
environment by remote command. Telik Trafo Lite is an End Device.
2) Gateways: These are the devices that receive messages from End Devices and send these messages to Network Servers. A single Gateway
can receive messages from several End Devices. In addition, multiple Gateways can receive messages from the same End Device, which
allows better coverage and reliability for the network.
3) Network Server: This is the server that receives and manages the messages received by the Gateways. A single Network Server can
receive messages from several Gateways.
4) Application Server: This is the server that communicates with the Network Server and processes the data produced by the End Devices,
in other words, where the data produced by the End Devices are forwarded to and where the messages that should be sent to the End
Devices come from.
5.2.1 HOW TO FORMAT TELIK TRAFO LITE MESSAGES

NOVUS AUTOMATION 14/31
6OPERATION
Telik Trafo Lite monitors the transformer temperature, performing acquisitions at configurable regular intervals and publishing the acquired data
(also at configurable regular intervals) through the LoRaWAN protocol. The published data is received by a Network Server, which, in turn, forwards
it to a cloud application, such as NOVUS Cloud.
There are two ways to publish data:
1) Confirmed mode: In confirmed mode, the device sends the message and waits for a confirmation from the Network Server before
considering the sending successful.
2) Non-confirmed mode: In non-confirmed mode, messages are sent and considered successful without any confirmation. There is no
guarantee of message delivery.
Although the LoRaWAN protocol recommends you use non-confirmed messages to reduce the number of messages transmitted in the network (since
each confirmation counts as one message), it has a message confirmation feature to minimize data loss. Still, there is no guarantee that 100 % of
the messages will be delivered. There may be times when no Gateway received the message from the device, either due to packet collision or poor
coverage at the time of publication.
To minimize data loss, Telik Trafo Lite has an internal memory that, when in confirmation mode, allows to store up to 10 messages for later
retransmission (in case the device does not receive confirmation of the messages sent). This feature can increase the number of messages
transmitted on the network and, consequently, produce a possible additional cost in the LoRaWAN plan, as well as increase battery consumption and
decrease autonomy. Nevertheless, it is an important feature to ensure message delivery, especially in a region with poor coverage.
The LoRaWAN protocol has an ADR (Adaptive Data Rate) mode, which, when enabled, regardless of whether the message sending configuration is
"confirmed" or "non-confirmed", allows the Network Server to request reconfigurations in power and transmission rate. This is used to try to ensure
effective communication between the device and the Gateway that receives the messages and sends them to the Network Server.
Besides ADR mode, Telik Trafo Lite has algorithms that automatically reconfigure the transmission parameters upon receiving no response to
confirmed messages and no response to a Join request.
Data Rates related to the SF (Spreading Factor) are defined in the LoRaWAN protocol. The higher the SF, the lower the Data Rate.

Table 12 –Spreading Factor
Transmission power levels are also defined in the LoRaWAN protocol. Both the transmission power and the Data Rate influence the battery lifespan.
This happens because in a place with poor coverage, Telik Trafo Lite needs to spend more energy (with a lower Data Rate and higher transmission
power) to successfully publish a packet.

Table 13 –LoRaWAN index
Each Telik Trafo Lite has a unique and non-configurable identifier (DevEUI). In addition, each device has a JoinEUI and an AppKey. These two
parameters are configurable. You will need this set of identifiers to connect to any Network Server.
1)
Choosing confirmed mode impacts data consumption. In this mode, sending one message accounts for two messages
in the data packet, i.e., data consumption in confirmed mode is twice as high as in non-confirmed mode.
2) If your Telik Trafo Lite is configured to send non-confirmed messages and the Network Server is not receiving the
messages and/or the device is repositioned, it is recommended to turn the device off and on again so that it starts Join
with lower power and Data Rate and later reconfigures the most appropriate parameters (if ADR is enabled) with the
Network Server.
3) Telik Trafo Lite automatically renews the connection to the Network Server 24 hours after a connection is established. In
other words, the connection will be renewed at least once a day.

NOVUS AUTOMATION 15/31
6.1 TELIK TRAFO LITE CONFIGURABLE PARAMETERS
Through NXperience software, you can configure the following parameters:
•Publication interval:Allows you to set the time in minutes between regular publications. In this interval, the device will publish a temperature
analysis of the last interval. From 1 to 1440 minutes (24 hours).
•Acquisition interval: Allows you to set the time in seconds between acquisitions. This interval must be less than or equal to the publication
interval. These acquisitions will be used to generate the analytical data that will be published in the publication interval and for the device to
analyze alarm situations that may generate instant messages.From 10 to 43200 seconds (12 hours).
•Confirmation of recurrent messages:Allows you to define whether messages that are sent frequently should receive confirmation. When this
feature is enabled, the device will wait for a confirmation response from the Network Server after a message is sent.
If this confirmation is not received, the device will try to send the message again, placing it in a circular queue for later publishing in case of
failure.
When this feature is disabled, messages are sent, and the sending is considered successful and there is no delivery confirmation.
•Confirmation of alarm messages:Identical to the previous parameter but applied only for alarm messages.
•Alarms: Allows the device to send messages informing you of the beginning and end of an alarm condition.
•Maximum temperature alarm: Allows alarm conditions to be checked at each acquisition interval. This is the minimum time required for an
alarm to change its status.
oSetpoint: Value to be exceeded to satisfy the alarm situation. From 0 to 125 °C (32 to 257 °F).
oHysteresis: Barrier to be overcome to leave the alarm situation.From 0 to 10 °C (32 to 50 °F).
•Maximum heating rate: Allows you to set the maximum allowed heating rate per time interval. The value is informed in °C/hour. From 0 to 100
°C/hour (32 to 212 °F/hour).
•Hysteresis for heating rate:Allows you to define how many °C/hour the heating rate must decrease for the device to leave the alarm condition.
From 0 to 50 °C/hour (32 to 122 °F/hour).
•Low battery alarm: Allows the device to send messages about the battery alarm. Battery voltage is checked only once a day.
•Minimum battery voltage: Allows you to define the voltage that the battery can reach in transmission mode. If the voltage is lower than the
configured value, the device will enter alarm condition. The value is informed in Volts (see BATTERY LIFESPAN section). From 2.0 to 7.0 Volts.
•Hysteresis:Allows you to define how many Volts above the minimum voltage the battery must reach in transmission mode to leave the alarm
condition. The value is informed in Volts. From 0 to 2.0 Volts.
•ADR mode:When enabled, it obeys commands received from the Network Server to reconfigure the transmission system (if it is within the limits
configured on the device).
•Initial transmission power: Power used at system startup. From 10 to 20 db.
•Minimum transmission power: Lower power limit of the operation.
•Maximum transmission power: Higher power limit of the operation.
•Initial SF: SF used at system startup. From 7 to 12.
•Minimum SF: Operation lower limit.
•Maximum SF: Operation higher limit.
•JoinEUI: Application identifier. You are only allowed to write to this field when the device is configured on an application server other than NOVUS
Cloud.
