Functional principle
A metallic measuring cell is used as sensor element. The process
pressures are transmitted via separating diaphragms and filling oils to
the resistance measuring bridge (semi-conductor technology). The
differential-pressure dependent change of the bridge voltage is
measured, further processed and converted into a corresponding
output signal.

3.4 Packaging, transport and storage
Packaging
Transport
Transport inspection
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 environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also us ed. Dispose of the packaging material via specialised
recycling companies.
Caution:
Instruments for oxygen applications are sealed in PE foil and provided
with a label "Oxygen! Use no Oil". Remove this foil just before
mounting the instrument! See instruction under "Mounting".
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

4.1 General instructions
Suitability for the process conditions
Mounting position
Moisture
Ventilation
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" 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 DPT10 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.
The ventilation for the electronics housing is realised via a filter
element in the vicinity of the cable glands.
Fig. 9: Position of the filter element with single and double chamber housing
1 Filter element for ventilation of the electronics housing
2 Blind stopper
Information:
Make sure that the filter element is always free of buildup during
operation. A high-pressure cleaner must not be used for cleaning.

Effective pressure lines
Vibrations
Temperature limits
Oxygen applications
You find general recommendations for wiring of effective pressure
lines in DIN 19210 "Effective pressure lines for flow systems" or the
corresponding national or international standards. When wiring
effective pressure lines outdoors, keep in mind to use a suitable
antifreeze, e.g. by using tube heat tracing. Wire effective pressure
lines with a monotonic decrease of at least 10 %.
In case of strong vibrations at the application position, the instrument
version with external electronics should be used.
Higher process temperatures often mean also higher ambient
temperatures for electronics and connection cable. Make sure that the
upper temperature limits stated in chapter "Technical data" for the
environment of the electronics housing and connection cable are not
exceeded.
4.2 Special application conditions
Oxygen and other gases can be explosive with oils, grease and
plastics so that the following provisions must also be taken:
l All components of the plant, such as e.g. measuring instruments
must be cleaning according to the requirements of BAM
(DIN 19247)
l Depending on the materials used, a certain max. temperature and
pressure must not be exceeded in oxygen applications
Danger:
Instruments for oxygen applications must be unpacked just before
mounting. After removing the protective cover of the pr ocess fitting, the
label "O₂" will be visible on the process fitting. Penetration of oil,
grease and dirt should be avoided. Danger of explosion!
Pure gas applications
We also offer oil and grease free instruments for special applications
such as e.g. ultra-pure gas. There are no special restrictions with
respect to the process conditions.

Selecting connection
cable
Cable screening and
grounding
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 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".
DPT10 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.

Leak flow volume suppression with flow
Total amounts counter
and subtotalizer with
flow
In some application, small flow quantities should not be detected. With
the creeping quantity suppression, the flow value can be suppressed
up to a certain % value. The default value is 5 % of the max. flow value,
corresponding to 0.25 % of the max. differential pressure value. The
limit value is 50 %. This function depends on the selected linearization
function and is only available with root extracted characteristics.
The square root/bidirectional square root characteristics is very steep
at the zero point. This means that small changes in the measured
differential pressure cause big changes in the output signal. The leak
volume suppression stabilises the signal output.
The DPT10 has two internal totalizers. For both you can adjust volume
or mass as count function as well as separately the unit.

6.7 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 DPT10 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".

Maintenance
Reaction when malfunc-
tions occur
Causes of malfunction
Fault rectification
Checking Profibus PA
When the instrument is used properly, no special maintenance is
required in normal operation.
In some applications, product buildup on the separating diaphragms
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.
9.2 Rectify malfunctions
The operator of the system is responsible for taking suitable measures
to rectify malfunctions.
DPT10 offers maximum reliability. Nevertheless, faults can occur
during operation. These may be caused by the following, e.g.:
l Sensor
l Process
l Voltage 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
this way and faults rectified.

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

11.2 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 DPT10 the ID
number is 0 x 0BFB(hex) and the GSD file DF650BFB.GSD. Optionally to this manufacturer-specific
GSD file, PNO provides also a general so-called profile-specific GSD file. For DPT10 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.
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, DPT10 provides the following modules:
l AI (PA-OUT)
- 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.
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.
