3. Safety
3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious
injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries
or damage to property or the environment, if not avoided.
DANGER!
... identifies hazards caused by electric power. Should the safety
instructions not be observed, there is a risk of serious or fatal injury.
WARNING!
... indicates a potentially dangerous situation that can result in burns,
caused by hot surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information for efficient
and trouble-free operation.
3.2 Intended use
The model TFS35 bimetal temperature switches are used to limit temperatures within a
wide variety of industrial applications.The TFS35 are temperature limiting instruments.
They are not intended to provide any safety or protective functionality.They are
designed for use in environments up to pollution degree 2.
They monitor the temperature of machinery and equipment during normal operation
and, for example, switch off machinery if it overheats.
Bimetals form the basis of the model TFS35 temperature switches.Temperature
sensing is carried out by a bimetal disc, which snaps over when the Nominal Switching
Temperature (NST) is reached. After cooling back down to the reset switching
temperature (RST), the switch returns to its original state, so that the monitored
equipment can again work normally.

The instruments are not approved for use in hazardous areas!
The bimetal temperature switch has been designed and built solely for the intended use
described here, and may only be used accordingly.
The technical specifications contained in these operating instructions must be
observed. Improper handling or operation of the bimetal temperature switch outside
of its technical specifications requires the instrument to be taken out of service
immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and
injuries.
▶
Refrain from unauthorised modifications to the instrument.
▶
Do not use the instrument within hazardous areas.
▶
Do not use the instrument with abrasive or viscous media.
Any use beyond or different to the intended use is considered as improper use.
Do not use this instrument in safety or emergency stop devices.
3.4 Responsibility of the operator
The instrument is used in the industrial sector.The operator is therefore responsible for
legal obligations regarding safety at work.
The safety instructions within these operating instructions, as well as the safety, accident
prevention and environmental protection regulations for the application area must be
maintained.
The operator is obliged to maintain the product label in a legible condition.
To ensure safe working on the instrument, the operating company must ensure
■
that suitable first-aid equipment is available and aid is provided whenever required.
■
that the operating personnel are regularly instructed in all topics regarding work
safety, first aid and environmental protection and know the operating instructions and
in particular, the safety instructions contained therein.
■
that the instrument is suitable for the particular application in accordance with its
intended use.
■
that personal protective equipment is available.

3.5 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to
property.
▶
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualifications described
below.
▶
Keep unqualified personnel away from hazardous areas.
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel
who, based on their technical training, knowledge of measurement and control
technology and on their experience and knowledge of country-specific regulations,
current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during
internal transport, proceed carefully and observe the symbols on the
packaging.
▶
With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +85 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
Avoidance of exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, flammable atmospheres
Store the bimetal temperature switch in its original packaging in a location that fulfils
the conditions listed above. If the original packaging is not available, pack and store the
temperature switch as described below:
1. Wrap the temperature switch in an antistatic plastic film.
2. Place the temperature switch, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.

5. Commissioning, operation
WARNING!
Physical injuries and damage to property and the environment
caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
CAUTION!
Damage to the instrument
When working on open electric circuits (printed circuit boards) there is a
risk of damaging sensitive electronic components through electrostatic
discharge.
▶
The correct use of grounded working surfaces and personal armbands
is required.
5.1 Mounting
When the temperature switch is mounted, the temperature must neither drop below the
allowed operating temperature (environment, medium) nor exceed it, even when taking
convection and heat radiation into account.
The installation site must be protected from weather influences and permanent UV
exposure/sun radiation.
Depending on the type of application, the electrical connection must be protected from
mechanical damage.
5.2 Electrical connection
DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶
The instrument may only be installed and mounted by skilled
personnel.
▶
Operation using a defective power supply unit (e.g. short circuit from
the mains voltage to the output voltage) can result in life-threatening
voltages at the instrument!
▶
Only connect in an unpowered state!
▶
Only disconnect the mating connector with the voltage disconnected.
▶
Use suitable mating connectors for the current and voltage ranges.
