2. Note
Please read these operating instructions before unpacking and putting the unit into
operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
The devices are only to be used, maintained and serviced by persons familiar with
these operating instructions and in accordance with local regulations applying to
Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of the
delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
 Electronic Temperature Switch model: TDD

4. Regulation Use
Any use of the device, which exceeds the manufacturer’s specification, may
invalidate its warranty. Therefore, any resulting damage is not the responsibility of
the manufacturer. The user assumes all risk for such usage.
5. Operating Principle
The KOBOLD Model TDD temperature sensor is used for economical measuring
and monitoring of temperature. It can be used for any application in which
temperatures must be monitored with great accuracy.
The sensor element is a semiconductor that outputs a digital signal to the electronic
processor in 0.5 °C steps. The measured values are shown on a 3-digit LED
display. The switch setpoint can be adjusted as required within the measuring
range.

6. Mechanical Connection
Before installation:
 Please check, if the switching temperature and switching function of TDD
device is in agreement with your system requirements (specifications).
 Ensure that the maximum operating pressure or temperature for the device
is not exceeded.
Installation:
 This device is installed in a matching sleeve. Use sealing tape (i.e. Teflon
tape) or a flat gasket to seal the threaded connections.
 The mounting position should be selected so that the sensor tip is always
immersed in the liquid being monitored, thus ensuring optimal heat
exchange between the liquid and the temperature sensor.
 Note that deposits that build up on the sensor tip or dirty liquids can have
an insulating effect and cause invalid measurements.
 Whenever possible, after the mechanical installation is complete, the joint
at the threaded connector and the supply piping should be checked to
ensure that it is tight and does not leak.

7. Electrical Connection
Attention! Make sure that the supply voltage of your system
corresponds with the voltage of the measuring unit specified on
the nameplate.
 Make sure that the supply wires are de-energized.
 Make the connection using the M12x1 connector socket, as shown in the
accompanying diagram.
 Appropriate connectors with different cable lengths are optionally available.
Attention! Incorrect wiring will lead to damage the unit’s
electronics.

8. Commissioning
Attention! Please take note that during operation at high
temperatures, the surface and the elements within the unit may
become very hot!
Connect the temperature switch according to the figure shown on the previous
page, and supply the device with the specified voltage.
