3.2Principle of operation
IPT-1*Vers.4.0is a pressure transmitter for use in the paper,food
processing and pharmaceutical industries as well as in water/sewage
water plants.Depending on the version,it is used for level,gauge,
absolute pressure or vacuum measurement.Measured products are
gases,vapours and liquids,also those containing abrasive substan-
ces.
Ameasuring cell with front-flush,abrasion-resistant diaphragm is the
sensor element.The hydrostatic pressure of the product or the
process pressure effects a capacitance change in the measuring cell
via the diaphragm.This change is converted into a respective output
signal and outputted as measured value.
The ceramic measuring cell is also equipped with a temperature
sensor.The temperature value can be displayed via the indicating and
adjustment module or processed via the signal output.
Power supply via the Profibus DP/PA segment coupler.Atwo-wire
cable according to Profibus specification serves as carrier of both
power and digital data transmission for multiple sensors.The
instrument profile of IPT-1*Vers.4.0corresponds to profile specifi-
cation version 3.0.
The GSD (instrument master files)and bitmap files necessary for
planning your Profibus-DP-(PA)communication network are available
from the download section on the WIKA homepage www.wika.com
under "Service".There you can also find the appropriate certificates.In
aPDM environment,an EDD (Electronic Device Description)is also
required to enable the full range of sensor functions (also available as
a download).A CD with the appropriate files can be ordered via e-mail
under [e-mail] or by phone from one of the WIKA
agencies.
The backlight of the indicating and adjustment module is powered by
the sensor.Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
This function is available at a later date for instruments with StEx,
WHG or ship approval as well as country-specific approvals such as
those according to FM or CSA.
3.3Operation
IPT-1*Vers.4.0can be adjusted with different adjustment media:
lwith indicating and adjustment module
lthe Simatic adjustment program PDM
The entered parameters are generally saved in IPT-1*Vers.4.0,
optionally also in the indicating/adjustment module.

3.4Packaging,transport and storage
Your instrument was protected by packaging during transport.Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging.Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt.Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation,the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated,the packages must be stored only under
the following conditions:
lNot in the open
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration
lStorage and transport temperature see chapter "Supplement -
Technical data -Ambient conditions"

4Mounting
4.1General instructions
Make sure that all parts of the instrument in contact with the measured
product,especially the sensor element,process seal and process
fitting,are suitable for the existing process conditions such as process
pressure,process temperature as well as the chemical properties of
the medium.
You can find the specifications in chapter "Technical data"in the or on
the type label.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module.The housing can be rotated by 330°without the use of any
tools.You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry.Rain and condensation water can thus drain off.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g.through cleaning processes)or
on cooled or heated vessels.
Fig.2:Measures against moisture penetration
The ventilation of the measuring cell is realised by a filter element in
the socket of the electronics housing.The ventilation of the electronics
housing is realised via an additional filter element around the cable
glands.1)
1)With previous instrument versions,ventilation and pressure compensation
were carried out together via a filter element.

Make sure that the filter elements are always free of buildup during
operation.Apressure washer must not be used for cleaning.
Higher process temperatures mean often also higher ambient
temperatures.

4.2Mounting steps
To mount IPT-1*Vers.4.0,a welded socket is necessary.Use
components from the line of WIKA mounting accessories:
àNote the applicable welding standards (segment welding proce-
dure)when welding the socket.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters should
be installed according to Profibus specifications
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the sensors
and power supply units.
Power is supplied via a Profibus DP/PA segment coupler.The power
supply range can differ depending on the instrument version.The
exact range is stated in the "Technical data".
IPT-1*Vers.4.0is connected with screened cable according to the
Profibus specification.Power supply and digital bus signal are carried
over the same two-wire connection cable.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the
Profibus specification.In particular,make sure that the termination of
the bus is done with appropriate terminating resistors.
In systems with potential equalisation,connect the cable screen
directly to ground potential at the power supply unit,in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).
In systems without potential equalisation,connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor,the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g.1nF,1500 V). The low
frequency potential equalisation currents are thus suppressed,but the
protective effect against high frequency interference signals remains.
The total capacitance of the cable and of all capacitors must not exceed
10 nFin Ex applications.

Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove it by
turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip approx.
1cm (0.4in)insulation from the ends of the individual wires
5Insert the cable through the cable gland into the sensor
6Lift the opening levers of the terminals with a screwdriver (see
following illustration)
7Insert the wire ends into the open terminals according to the wiring
plan
