Aplication and short description
Temperature-Relays TR 111 V can be used as limit-switches or 2-point controllers with high
repeat accuracy.
3 measuring-ranges, adjustable hysteresis and switching delay and the choice between
operating- and closed-current principle of the relay make it a very universal device.
Protection from over-temperature in processes, plants and machines.
Monitoring of temperatures in bearings.
Controlling of temperatures in processes and plants.

Detailed description
As standard, the TR 111 V thermostats operate according to the closed-current-principle. If a
temperature sensor is connected, the installed relay picks up (11-14 closed = ok).
The relay releases in the case of a sensor breakdown.
The thermostat signals and switches when the set limit is exceeded.
If the temperature at the sensor rises over the adjusted value, then the relay releases. The
switching status is signalled by a LED: relay picked up = LED on.
At operating-current-principle the function pf the relay is inverted. It picks up at over-
temperature (11-12 closed = ok).

Important notes
To use the equipment flawless and safe, transport and store properly, install and start
professionally and operate as directed.
Only let persons work with the equipment who are familiar with installation, start and use and
who have appropriate qualification corresponding to their function. They must observe the
contents of the instructions manual, the information which are written on the equipment and
the relevant security instructions for the setting up and the use of electrical units.
The equipments are built according to EN and checked and leave the plant according to
security in perfect condition. To keep this condition, observe the security instructions with the
headline „Attention“ written in the instructions manual. Ignoring of the security instructions
may lead to death, physical injury or damage of the equipment itself and of other apparatus
and equipment.
If, in any case the information in the instructions manual is not sufficient, please contact our
company or the responsible representative.
Instead of the industrial norms and regulations written in this instructions manual valid for
Europe, you must observe out of their geographical scope the valid and relevant regulations
of the corresponding country.
Attention!
Before switching on make sure that the operational voltage Us of the lateral type plate
and the mains voltage are the same.
Assembly
mount on 35 mm mounting rail according to EN 60715
wall-mount with 2 x screws M4
connecting wires refer to the wiring diagram.
Putting into operation
•Connect Pt 100 sensor
•Switch on mains voltage
•Relay releases when set temperature is exceeded, the relevant LED is switched on.
Trouble shooting
Die Funktion des Gerätes kann mit einem Pt 100 - Simulator oder nach der Widerstands-
tabelle für Pt 100 Sensor EN 60751 überprüft werden. Das Relais schaltet ab bei
überschreiten des eingestellten Grenzwertes, bei Sensorbruch oder Sensorkurzschluss.
