1. General information / 2. Safety
Information
... points out useful tips, recommendations and information for ecient and
trouble-free operation.
DANGER!
...identies 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.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
switch has been selected in terms of switching temperature, design and specic
measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
Further important safety instructions can be found in the individual chapters of
these operating instructions.
2.1 Intended use
The model TFS35 bimetal temperature switches are used to limit temperatures within a
wide variety of applications.
GB
They monitor the temperature of machinery and equipment and, for example, switch off
machinery if it overheats or switch on a fan to cool the equipment.
Bimetals form the basis of the model TFS35 temperature switches. Temperature sensing is
carried out by a bimetallic disc, which snaps over when the Nominal Switching Temperature
(NST) is reached. On 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.
11610115.03 11/2012 GB/D/F/E
WIKA operating instructions model TFS35 5
2. Safety
The bimetal temperature switch has been designed and built solely for the intended use
described here, and may only be used accordingly.
The technical specications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specications
GB
requires the bimetal temperature switch 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.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried
out by skilled personnel who have the qualications described below.
Keep unqualied personnel away from hazardous areas.
Skilled personnel
Skilled personnel 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-specic 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.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or
liquids, and refrigeration plants, compressors, etc., in addition to all standard
regulations, the appropriate existing codes or regulations must also be followed.
WARNING!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal wrist straps is required
when working with exposed circuitry (printed circuit boards), in order to prevent
static discharge from damaging sensitive electronic components.

2. Safety / 3. Specications
To ensure safe working on the instrument, the operating company must ensure
that suitable rst-aid equipment is available and aid is provided whenever
required.
that the operating personnel are regularly instructed in all topics regarding
work safety, rst aid and environmental protection, and know the operating
instructions, in particular the section on safety instructions.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
The instrument may only be installed and mounted by skilled personnel.
Any connection work may only be carried out once the equipment has been
isolated.
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 bimetal temperature switch!
WARNING!
Residual media in the dismounted instrument can result in a risk to persons, the
environment and the equipment. Take sucient precautionary measures.
Do not use this instrument in safety or Emergency Stop devices. Incorrect use of
the instrument can result in injury.
GB
Should a failure occur, aggressive media with extremely high temperature and
under high pressure or vacuum may be present at the instrument.
3. Specications
Temperature ranges
Nominal Switching Temperature (NST)
50 ... 200 °C
Note:
The nominal switching temperature can be selected in steps of 5 K. It is preset on
delivery and cannot be changed.
Switch point accuracy
±5 K

WIKA operating instructions model TFS35 7
3. Specications
Reset Switching Temperature (RST)
The reset switching temperature in bimetal temperature switches is typically 15 ... 30 K
below the switching temperature.
To ensure a safe reset of the switch at low switching temperatures, care must be
GB
taken that the temperature dierence between the measuring point and ambient is
high enough; since otherwise the switch cannot cool back down to the reset switching
temperature and thus the equipment will not be able to return to its normal state.
Ambient temperature
-50 ... +125 °C
Note:
With small insertion lengths there is a possibility that the temperature at the connector
can reach impermissibly high values. This absolutely must be taken into account in the
design of the measuring point.
Vibration resistance
Depending on the mounting situation, the medium, temperature and insertion length, the
vibration resistance is up to 10 g.
Shock resistance
Up to 100 g, depending on the mounting situation, medium and temperature

Store the bimetal temperature switch in its original packaging in a location that fulls
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 lm.
GB
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.
WARNING!
Before storing the temperature switch (following operation), remove any residual
media. This is of particular importance if the medium is hazardous to health, e.g.
caustic, toxic, carcinogenic, radioactive, etc.
6. Commissioning, operation
6.1 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.
6.2 Electrical connection
WARNING!
Only connect when the system is powered down!
Cables and wires
