2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
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.

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
correspond with the voltage of the measuring unit specified on the
nameplate.

• Make sure that the electrical supply lines are de-energised.

• Make the connection using the M 12x1 connector socket, as shown in the

accompanying diagram.

• Appropriate connectors with different cable lengths are optionally available.

Attention! Incorrect wiring will lead to damage of the unit’s
electronics.
