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 model A-1200 pressure sensor is used for the switching of circuits as a function of the measured pressure
via a PNP or NPN output signal. In addition, the pressure value can be output to appropriate read-out units as a
standardised digital signal (IO-Link 1.1).The switching conditions can optionally be programmed using IO-Link 1.1
(switch and reset points, switching functions, time response, …) or congured using the teach function (switch point 1,
switching function).
The model A-1200 has been developed for the pressure measurement of non-hazardous uids, liquids and gases
(classication in accordance with Directive 2014/68/EU Article 13, Regulation (EC) No. 1272/2008, or GHS1) ) which
are mainly used for cooling, lubrication, cleaning or power transmission in industrial machines.

3. Safety
WARNING!
Physical injuries and damage to property and the environment through exceeding the
performance limits
Exceeding the performance limits can destroy the instrument and lead to danger in the end-use appli-
cation.
▶
Only use the instrument in applications that lie within its technical performance limits. → For
performance limits, such as derating (maximum current consumption at a corresponding medium
temperature), see chapter 9 “Specifications”.
▶
Any permanent operation in the overload range is not permitted. Above the highest permissible
operating pressure, up to the overload limit, the pressure sensor is operating outside its specifica-
tion.The overload range is intended to prevent damage to the pressure sensor, as part of a pressure
vessel system, during the pressure containment test.
▶
The overload limit must never be exceeded, even when failures occur in the end-use application.
Loads above the overload limit can cause irreversible damage, which can lead, for example, to
permanent measuring errors.
▶
The manufacturer or operator of the machine or plant in which the product is used must ensure the
compatibility of the materials of the wetted parts with the medium used.
▶
The pressure switch should not be used with abrasive or unstable fluids, in particular not with
hydrogen.
Special versions for oil and grease-free applications, as well as for use with oxygen (dangerous uid in accordance
with Directive 2014/68/EU Article 13, Regulation (EC) No. 1272/2008, or GHS 1)), are available on request.
The (dis-)mounting, installation, parameterisation and maintenance of the model A-1200 in industrial environments
absolutely requires suitably skilled personnel in accordance with chapter 3.3. “Personnel qualication”.
■
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 0.6 mm and thus increases the resistance against pressure
spikes.
■
With media that could block the pressure port (e.g. through particles), it is recommended to use a
wider pressure port of 6 or 12 mm.
■
It must be ensured that no atomic hydrogen can form in the pressure port of the pressure sensor.

3.3 Personnel qualication
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.
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.
3.5 Labelling, safety marks

4. Transport, packaging and storage
4.1 Transport
Check the pressure sensor for any damage that may have been caused by transport.
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: -40 ... +70 °C [-40 ... +158 °F]
■
Humidity: 45 ... 75 % relative humidity (non-condensing)
5. Commissioning, operation
5.1 Checking the instrument
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
■
Leaking uid is indicative of damage.
■
Only use the pressure sensor if it is in perfect condition with respect to safety.
5.2 Requirements for mounting point
The mounting point must meet the following conditions:
■
Protected from weather inuences. Permanent exposure to UV light/sunlight can lead to a change in the colour of
the plastic parts and a clouding/yellowing of the status display.Therefore, a possible limitation of the visibility of the
status display cannot be excluded.
■
Under corrosive environmental conditions (such as salty, humid air), reductions in the gloss level of the metal
surfaces, or even corrosion on the instrument, may occur, which make readability of the product label more dicult.
■
Sealing faces are clean and undamaged.
■
Sucient space for a safe electrical installation.
■
The instrument is vented to the atmosphere.Therefore, no coating or other covering may be applied which might
restrict the venting.
■
For information on tapped holes and welding sockets, see Technical information IN 00.14 at www.wika.com.

5. Commissioning, operation
WARNING!
Physical injuries and damage to property and the environment through running above or
below the temperature limits
Running above or below the temperature limits can destroy the instrument and lead to danger in the
end-use application.
▶
Permissible ambient and medium temperatures remain within the performance limits. Consider
possible restrictions on the ambient temperature range caused by mating connector used.
For performance limits, such as derating (maximum current consumption at a corresponding
medium temperature), see chapter 9 “Specifications”
5.3 Mechanical mounting
The max. torque depends on the mounting point (e.g. material and shape). If you have any questions,
please contact our application consultant.
→ For contact details see chapter 1 “General information” or the back page of the operating instructions.
