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.

sensor, the address setting must first be carried out. You will find a
detailed description in the operating instructions manual of the
indicating and adjustment module or in the online help of PACTware or
DTM.
IPT-1* Vers. 3.0 can be used for level as well as for process pressure
measurement. D efault setting is level measurement. The mode can be
changed in the adjustment menu.
Depending on the application only the respective subchapter "Level or
process pressure measurement" is of importance. There, you find the
individual adjustment steps.
Level measurement
Set up IPT-1* Vers. 3.0 in the following sequence:
1 Selecting adjustment unit/density unit
2 Carry out position correction
3 Carrying out min. adjustment
4 Carrying out max. adjustment
In the menu item "Adjustment unit" you select the physical unit in which
the adjustment should be carried out, e.g. mbar, bar, psi…
The position correction compensates the influence of the mounting
position or static pressure on the measurement. It does not influence
the adjustment values.
Information:
The steps 1, 3 and 4 are not necessary for instruments which are
already preset according to customer specifications!
You can find the d ata on the type label on the instrument or in the
menu items of the min./max. adjustment.
The indicating and adjustment module enables the adjustmetn without
filling or pressure. Thanks to this, you can carry out your settings
already in the factory without the instrument having to be installed.
The actual measured value is also displayed in the menu items for
min./max. adjustment.
In this menu item you sel ect the adjustment unit as well as the unit for
the temperature indication in the display.
To select the adjustment unit (in the example switching over from bar
to mbar) you have to proceed as follows:

6.6 Saving the parameter adjustment data
It is recommended noting the adjusted data, e.g. in this operating instructions manual and archive them afterwards. They are hence available for multiple use or service purposes.
If IPT-1* Vers. 3.0 is equipped with an indicating and adjustment module, the most important data can be read out of the sensor into indicating and adjustment module. The procedure is described in the operating instructions manual "Indicating and adjustment module" in the menu item "Copy sensor data". The data remain there permanently even if the sensor power supply fails.
If it is necessary to exchange the sensor, the indicating and adjustment module is inserted into the replacement instrument and the data are written into the sensor under the menu item "Copy sensor data".

8 Maintenance and fault rectification
8.1 Maintenance, cleaning
When used in the correct way, no special maintenance is required in normal operation.
In some applications, product buildup on the sensor diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided.
If necessary, the transmitter has to be cleaned. In this case, make sure that the materials are resistant against the cleaning detergents.
8.2 Remove interferences
The operator of the system is responsible for taken suitable measures to remove interferences.
A maximum of reliability is ensured. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:
l Sensor l Process l Power supply l Signal processing
The first measures to be taken are to check the output signals as well as to evaluate the error messages via the indicating and adjustment module. The procedure is described below. Further comprehensive diagnostics can be carried out on a PC with the software PACTware and the suitable DTM. In many cases, the causes can be determined in this way and faults can be rectified.
? When an additional instrument is connected, the segment fails.
l Max. supply current of the segment coupler exceeded
à Measure the current consumption, reduce size of segment
? Wrong presentation of the measured value in Simatic S5
l Simatic S5 cannot interpret the number format IEEE of the
measured value
à Insert converting component from Siemens
? In Simatic S7 the measured value is always presented as 0
l Only four bytes are consistently loaded in the PLC
à Use function component SFC 14 to load 5 bytes consistently

Approvals
Depending on the version, instruments with approvals can have different technical data. For these instruments, please note the corresponding approval documents. They are included in the scope of delivery.
23)
Instruments with gauge pressure measuring ranges cannot detect the am­bient pressure when submerged, e.g. in water. This can lead to falsification of the measured value.

10.2 Information on Profibus PA
Instrument master file
The instrument master file (GSD) contains the characteristic data of the Profibus PA instrument. These data are, e.g. the permissible transmission rates as well as information on diagnostics values and the format of the measured value outputted by the PA instrument.
A bitmap file is also provided for the Profibus network planning tool. This file is installed automatically
when the GSD file is integrated. The bitmap file is used for symbolic indication of the PA instrument in the configuration tool.
Ident number
Each Profibus instrument gets an unambiguous ident number (ID number) from the Profibus user organisation (PNO). This ID number is also included in the name of the GSD file. For IPT-1* Vers. 3.0 the ID number is 0 x 076F(hex) and the GSD file BR__076F.GSD. As an option to this manufacturer­specific GSD file, PNO provides also a general so-called profile-specific GSD file. For IPT-1* Vers.
3.0 you have to use the general GSD file PA139701.GSD. If the general GSD file is used, the sensor
must be set to the profile-specific ident number via the DTM software. By default, the sensor operates with the manufacturer-specific ID number.
Note:
When using the profile-specific GSD file, the PA-OUT value as well as the temperature value are transmitted to the PLC (see block diagram
"Cyclical data traffic").
Cyclical data traffic
The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during operation. The below block diagram below shows which data can be accessed by the PLC.

Module of the PA sensors
For the cyclic data traffic, IPT-1* Vers. 3.0 provides the following modules:
l AI (PA-OUT)
Process pressure transmitter IPT-1* Vers. 3.0 - metalic sensor • Profibus PA 47
10 Supplement
31544-EN-081211
Page 48
- PA-OUT value of the FB1 after scaling
l Temperature
- PA-OUT value of the FB2 after scaling
l Additional Cyclic Value
- Additional cyclical value (depending on the source)
l Free Place
- This module must be used if a value should not be used in the data telegram of the cyclical data
traffic (e.g. replacement of the temperature and Additional Cyclic Value)
Max. three modules can be active. By means of the configuration software of the Profibus master, you can determine the configuration of the cyclical data telegram with these modules. The procedure depends on the respective configuration software.
Tip:
The modules are available in two versions:
l Short for Profibus master supporting only one "Identifier Format"
byte, e.g. Allen Bradley
l Long for Profibus master only supporting the " Identifier Format"
byte, e.g. Siemens S7-300/400
Examples of telegram configuration
In the following you will see how the modules can be combined and how the appendant data telegram is structured.
