2.Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate switch has been selected in terms of switching temperature, design and specific 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 modelTFS35 bimetal temperature switches are used to limit temperatures within a wide variety of applications.
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 modelTFS35 temperature switches.Temperature sensing is carried out by a bimetallic disc, which snaps over when the Nominal SwitchingTemperature (NST) is reached.On cooling back down to the Reset SwitchingTemperature (RST), the switch returns to its original state, so that the monitored equipment can again work normally.

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 specifications contained in these operating instructions must be observed. GB Improper handling or operation of the instrument outside of its technical specifications
requires the bimetal temperature switch to be taken out of service immediately and inspected by an authorisedWIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
2.2 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient!
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 qualifications described below.
Keep unqualified 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-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.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, flammable 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.Specifications
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 |
|
|
GB |
||
work safety, first 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 sufficient precautionary measures.
Do not use this instrument in safety or Emergency Stop devices.Incorrect use of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum may be present at the instrument.

3.Specifications
Temperature ranges
Nominal SwitchingTemperature (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 modelTFS35 |
7 |
3.Specifications
Reset SwitchingTemperature (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 difference 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.
