3.2 Principle of operation
IPT-1* Vers. 3.0 is a pressure transmitter for measurement of
overpressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids in measuring ranges up to 4000 bar
(400 MPa); with front-flush version also viscous liquids in measuring
ranges up to 600 bar (60 MPa).
The process pressure acts on the sensor element via the stainless
steel diaphragm. The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted as
measured value.
1)
Power supply via the Profibus DP/PA segment coupler. A two-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. 3.0 corresponds 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
a PDM 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 info@de.WIKA.com 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.
3.3 Operation
IPT-1* Vers. 3.0 can be adjusted with different adjustment media:
l with indicating and adjustment module
l the Simatic adjustment program PDM
The entered parameters are generally saved in IPT-1* Vers. 3.0,
optionally also in the indicating/adjustment module.

4.1 General 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 t he chemical properties of
the medium.
You can find the specifications in chapter "Technical data" in the or on
the type label.
Caution:
After removal of the diaphragm protective cover, the diaphragm must
not be pressed.
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.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
l If 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 P rofibus 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. 3.0 is 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. A cable outer diameter of 5 … 9 mm
(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. 1 nF, 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 nF in 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.
