TC - PT100
Introduction
Warning
Developed for winding temperature control of resin or dry type MV transformers. It is
based on high level electromagnetic interference, also standardized. There are 4 PT100 sensor
inputs. The transformer core temperature or the ambient temperature can also be measured
from the 4th sensor input if the 3-phase transformer requests the winding temperatures
individually as well as it can be measured. There are 4 relay outputs, ALARM, FAULT, TRIP and
FAN.
The design, hardware and software were entirely made by KAEL engineers.
The state-of-the-art technology has been incorporated into this device and features have been
added that make it easier for the user to use both menus and features. The device has a color
LCD display (TFT).As a memory, the device has its own recording area and records error
reports.
All information and warnings that you need to know about the device are described in the user
manual. Please read this booklet carefully before commissioning your system and your own
safety equipment. Please do not make anything about the topics that are not being understood
without making any contact with our company.

The device must be commissioned and programmed by authorized and qualified persons in
accordance with the instructions in the operating instructions. If necessary, they should also be
inspected by these persons.
Do not open the device, do not make it opened. There are no serviceable parts inside the device
that any other user or person will intervene.
Use the device in accordance with installation instructions
Before making electrical connections to the terminals of the device, make sure that there is no
energy in the cables and terminals. There should not be energy in the panel.
The fuses to be used in the device must be 1A FF type.
Secure the appliance firmly so that it does not swing to the panel with the appliances supplied.
Do not interfere of the keys on the front panel of the device with anything other than your fingers.
Once you are sure that you have cut off your device, wipe it with dry cloth only. Chemicals used
in water or cleaning shall damage the device.
Make sure that the terminal connections are made in accordance with the connection diagram
and not in contact (loose connection or interconnection of multiple copper wires, etc.) before the
device is switched on (before energization).
The above precautions and warnings are for your safety. In case of non-compliance, KAEL
Elektronik Ltd. Sti. or vendors are not responsible.

General
The device that is developed to protect the windings of MV transformers and high-power
motors equipped with today's technology, is quite well equipped in terms of function richness and
has added a new product to its sector with its advanced software. Additionally, the microprocessor
inside is very fast and uses the operating system. This ensures that all operations can be
synchronized simultaneously.
Displaying the error and temperature values that may occur on the main screen during
device operation is as follows.

■ The connection of the device should be done without the system power.
■ The device must be connected as shown in the connection diagram.
■ Do the Pt100 sensor inputs as shown on the back of the unit
■ Do not energize the device without checking all connections using the meter.
Making Connections
Information Panel
The upper part of the screen of the device has an information panel consisting of icons easily
understood by the user. This panel is always on top of the screen no matter which part the user is
in. The date, time, device operation status, FAULT status, ALARM status, TRIP status, FAN status
information are observed in this panel at the same time. The operating status indicator indicates
OK if the system is normal and returns to exclamation point when an error occurs in the system.
A color LCD display is used in our device to make it much easier and clearer to use. If the
keys are not pressed for a long time, the device will switch to screen saver mode to extend the life
of the screen and only step down from the top of the screen with the information panel on top.
When any key is pressed, the main screen image appears again.
