CAUTION!
... indicates a potentially dangerous situation that can result in light injuries
or damage to equipment or the environment, if not avoided.
Information
... points out useful tips, recommendations and information for ecient and
trouble-free operation.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appro-
priate instrument has been selected in terms of measuring range, design
and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equip-
ment.
Further important safety instructions can be found in the individual
chapters of these operating instructions.
2.1 Intended use
The process transmitter measures gauge pressure, absolute pressure and vacuum. The
physical quantity pressure is converted into an electrical signal.
The process transmitter has been designed exclusively for industrial applications in
internal and external locations. Its scope of application is dened by its technical perfor-
mance limits and its materials. Improper use is dened as any application that exceeds
the technical performance limits or is not compatible with the materials. Checking
against improper use is the responsibility of the operator.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its technical
specications 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.

2. Safety
2.2 Personnelqualication
WARNING!
Riskofinjuryshouldqualicationbeinsucient!
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 qualications described below.
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 knowl-
edge of country-specic 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, compatibility of materials.
2.3 Personalprotectiveequipment
The personal protective equipment is designed to protect the skilled personnel from
hazards that could impair their safety or health during work. When carrying out dierent
work on and with the instrument, personal protective equipment must be worn.
Followtheinstructionsdisplayedintheworkarearegardingpersonalprotective
equipment!
The requisite personal protective equipment must be provided by the operating
company.
2.4 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!
Residual media in the dismounted process transmitter can result in a risk to
personnel, the environment and equipment.
Take sucient precautionary measures.

4.2 Description
The process transmitter processes the prevailing pressure and converts it into a current
signal. This current signal can be used for the evaluation, control and monitoring of the
process.

4. Design and function
Display and operating unit (accessory)
The display and operating unit model DI-PT-U has a main and an additional display.
The main display and the additional display are able to be set in almost any way. In the
factory setting, the main display shows the pressure value of the output signal.
The process transmitter is congured via the display and operating unit.
Adaptable to mounting position
The process transmitter is tted with a case head which can be turned through 330°.
The display and operating unit can be attached in 90° steps. Thus the measured value
can be read irrespective of the mounting position.

5. Transport, packaging and storage
5. Transport, packaging and storage
5.1 Transport
Check the process transmitter for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
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, return for calibration).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +80 °C
■
Humidity: 35 ... 93 % relative humidity (no condensation)
Avoidexposuretothefollowingfactors:
■
Proximity to hot objects, when permissible storage temperature is exceeded by
radiation
■
Mechanical vibration, mechanical shock (putting it down hard), when the permissible
values are exceeded, see chapter 3 “specications”
■
Soot, vapour, dust and corrosive gases
■
Hazardous areas and ammable atmospheres where the instruments are not suitable
for installation in or mounting to equipment in explosive atmospheres.
Store the process transmitter in its original packaging in a location that fulls the condi-
tions listed above. If the original packaging is not available, then store the instrument
in a container that is similar to the original packaging, so that the instrument can't be
scratched and is protected against damage if dropped.
WARNING!
Before storing the instrument (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.
