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.
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 ecient and trouble-free operation.
3.2 Intended use
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
Intended use
The PSD-4 pressure switch is used for the switching of circuits as a function of the measured pressure. In addition, the
pressure value can be output to appropriate read-out units as a standardised analogue signal.The switching conditions
can be programmed directly at the pressure switch (switch and reset points, ...). Via the dierent display elements,
switching statuses and pressure values can be read.
This is a class B instrument for emissions and is intended for use in industrial environments. In other environments,
e.g. residential or commercial installations, it can intefere with other equipment under certain conditions. In such
circumstances the operator is expected to take the appropriate measures.

Application areas
Only use the pressure switch in applications that lie within its technical performance limits (e.g. max. ambient
temperature, material compatibility, ...).
→ For performance limits see chapter 9 “Specications”.
Technical restrictions
■
The overload pressure must never be exceeded, even when failures occur in the end-use application. Loadings
above the overload safety can cause measuring errors.
■
Pressure surges below the nominal pressure and shorter than 1 ms can cause measuring errors.
■
For applications where pressure spikes can occur, the use of a restrictor is recommended.The restrictor narrows the
pressure port to 0.3 mm and thus increases the resistance against pressure spikes.
■
With media that could block the pressure port (e.g. through particles), a ush instrument version must be used.
■
With a high ambient temperature and a high UV irradiation, the pressure switch must be installed with additional
covering in order to avoid damage to the digital indicator and buttons.
■
The medium temperature at the instrument must not exceed 85 °C. With hotter media, a cooling element can
provide a solution (see chapter 10 “Accessories and spare parts”).
3.3 Personnelqualication
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-specic regula-
tions, 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.

3. Safety
3.4 Use of accessories and spare parts
It is recommended to use original accessories and original spare parts from WIKA. Using accessories and spare parts
from third parties can lead to damage to the instrument or accidents, due to quality defects or other reasons.
WIKA assumes no liability for damage or accidents caused by a malfunction or unsuitability of accessories and spare
parts which do not originate from WIKA (e.g. non-compliance with the IP ingress protection of connectors). No warranty
claims can be made which arise due to a malfunction or unsuitability of any accessory or spare part from a third party.

4. Transport, packaging and storage
4. Transport, packaging and storage
For the protection of the diaphragm, the ush design is delivered with a special protection cap.
▶
In order to avoid damage at the diaphragm and/or the process connection thread, remove the
protection cap by hand only just before installation.
▶
Keep the protection cap for subsequent storage or transport.
▶
Fit the protection cap before dismounting and transporting the instrument.
4.1 Transport
Check the pressure switch for any damage that may have been caused by transport. With ush design, additionally
check the diaphragm for any optical damage.
Obvious damage must be reported immediately.
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: -20 ... +70 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
In order to protect the diaphragm, mount the protection cap before storing the instrument.
