1 Use and brief description
Temperature relay to protect transformers against excess temperature and to control a fan.
The temperatures in the windings are monitored with three Pt 100 sensors. The core temperature can be
monitored with a fourth sensor.
The 4 alarms/output relays are used to control the fan, to signal an advance warning and to switch-off the
transformer. Various programs facilitate using the alarm ideally for each application. Depending on the
program, e.g. an extra relay is available for the fault message or for triggering due to exceeding the
maximum core temperature.
Other uses: Alternatively, with the fourth sensor the temperature of the room the transformer is located in
can be monitored and, with the alarm, the room ventilation can be controlled. The device can also be used
for other tasks for temperature monitoring
e.g., for motors.

5 Important information
WARNING
Hazardous electrical voltage!
Can lead to electric shock and burns.
Before starting work, switch plant and device voltage-free.
The flawless and safe operation of a device requires that it is shipped and stored appropriately,
professionally installed and put into operation and operated according to its intended use.
Only people who are familiar with the installation, commissioning and operation and who have
qualifications corresponding to their job are permitted to work on the device. They must comply with the
contents of the operating instructions, the notices attached to the device and the relevant safety
regulations for erecting and operating electrical plants.
The devices are built and certified in accordance with (DIN / VDE / EN / IEC) and leave the factory in a
safe and technically flawless condition. To maintain this state you must comply with the safety
regulations indicated with "Caution" in the operating instructions. Non-compliance with the safety
regulations can lead to death, bodily injury or property damage on the device itself and on other devices
and equipment.
If the information in the operating instructions is insufficient in any case whatsoever, please contact us
directly or contact the representation responsible for you.
Instead of the industrial norms and stipulations stated in the operating instructions and applicable in
Europe, you must comply with the valid and applicable instructions in the land of utilisation if the device
is used outside of the area of application.
Caution!
Devices with reclosing interlock (Reset) do not comply with
the conditions for safety circuits according to EN 60204. They must not
be used alone for functions in which an independent
restart must be prevented.
Caution!
If the operating current version is programmed for all relays, a failure of the control
voltage or the device will not be detected. When using as a monitoring device, the
operator must ensure that this error is detected through periodic function tests.
We recommend programming at least one relay in closed-circuit current version and
to correspondingly evaluate.
Attention! (Only devices with RS 485 interface)
Sensor-Inputs and Interface RS 485 are the same potential. Please regard.
RS 485 interface:
Large cable lengths may shift the potential ground and the transmission can be disturbed.
Corrective measures can be galvanic separation or an additional ground wire.

6 Programs
4 programs (Pr) can be selected in the factory version. Starting from these programs, it is especially simple to
adapt the device to the application.
First select the program that fits your application and then change the individual parameters! All parameters
are reset with when switching the program to "factory settings" (see "Connection Diagram" and see "Factor
Settings").
Selecting the program:
Switch off control voltage supply
Keep the Set key pressed
Switch on control voltage supply
Wait at least 10s until 8PR 8appears in the display
Release the Set key
Select program (Pr 1... Pr 4) with the Up/Down keys
Press the Set key
Select the measurand (°C / °F) with the Up/Down keys
Press the Set key
Display 8---8appears, settings will be copied, device starts
Querying the program number
See
Point 11.1 Display of program number, measurand and software version
7 Installation
Comply with the maximum permissible temperature when installing. Ensure sufficient clearance to
other devices or heat sources. If cooling is inhibited, e.g., through close proximity to devices with
increased surface temperature or interference with the cooling air current, the permissible ambient
temperature is decreased.
Caution! Wide area power supply
The device has a wide area power supply that is suitable for DC and AC
voltages. Before you apply mains voltage to the device, make sure that the
permissible voltage range of the control voltage Us on the rear of the device
matches the mains voltage connected to the device!
Push the TR440 into the prepared 91 x 91 mm cut-out according to DIN 43700 from the control side.
To achieve the IP 54 degree of protection, install the supplied seal between the housing and the front
panel.
Push the fastening clasp onto both sides of the guide rails.
Screw the fastening clasps tight with a screwdriver.
Tighten both clasps uniformly.
Connect in accordance with the connection diagram or the rating plate.
