Be sure to read and observe the following instructions!
The device has been designed in accordance with the state of the art
and complying with the applicable safety regulations.
When operating the device, certain conditions may nevertheless be
dangerous for the operator or cause damage to the device.
Whenever it is likely that protection has
been impaired, the device shall be made
inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
For hazardous-area applications, the
Transmitter may only be connected to
explosion-proof segment couplers, power
supplies, ....
The Transmitter may be operated in accordance with the FISCO
model.
The stipulations of EN 60079 - 10 : 1996 and
the following must be observed for the
installation.
- the device shows visible damage
- the device fails to perform the intended measurements
- after prolonged storage at temperatures above 70 ˚C
- after severe transport stress
Before recommissioning the device, a professional routine test in accordance with EN 61010-1 must be performed. This test should be
carried out by the manufacturer.

PROFIBUS technology
3.1
General
PROFIBUS is a digital communication system that connects different
field devices over a common cable and integrates them into a control
system. In the long term, PROFIBUS will replace the 4-20 mA technology, which only supplies pure measured values.
Advantages of the PROFIBUS technology are:
- easy and cost-saving cabling
- convenient operation over a central control station
- transmission, evaluation and control of high amounts of data from
field device to control station.
3.2
- devices installed in hazardous locations are configured and maintained from the control station
PROFIBUS is the leading open fieldbus system in Europe. Its application range covers manufacturing, process and building automation. As
open fieldbus standard to EN 50170, PROFIBUS ensures communication of different devices over one bus.
The PROFIBUS User Organization provides for further development
and maintenance of the PROFIBUS technology. It combines the interests of users and manufacturers.
Variants and basic characteristics
PROFIBUS determines the technical and functional characteristics of
a serial bus system.
There are three PROFIBUS variants:
- PROFIBUS-FMS (FMS protocol)
- is particularly suited for exchanging large amounts of data
between control devices. It operates according to the RS 485
standard with transmission rates up to 12 MBits/sec.
- PROFIBUS-DP (decentralized peripherals)
- Masters
- control the data traffic on the bus. They send messages without
external request.
- Slaves
- are peripheral devices such as valves, drives, transmitters and
analyzers. They can react acyclically to servicing, configuration
and diagnostic tasks of the master. The central controller cyclically reads the measurement data with status.
- is tailored for communication of automation systems and distributed peripherals. It operates according to the RS 485 standard with transmission rates up to 12 MBits/sec.
- PROFIBUS-PA (process automation)
- is dedicated to the process industry. It permits connection of
sensors and actuators to a common bus even in hazardous
locations. PROFIBUS-PA has a transmission rate of
31.25 kBits/sec.
PROFIBUS distinguishes between two types of devices:
PROFIBUS technology

3.3
Definitions for PROFIBUS-PA
The bus protocol defines type and speed of the data exchange between master and slave devices and determines the transmission protocol of the respective PROFIBUS system.
PROFIBUS-PA permits cyclic and acyclic services.
- Cyclic services are used for transmission of measurement data
and actuating commands with status information.
3.4
- Acyclic services are used for device configuration, maintenance
and diagnostics during operation.
The device profile defines the device class and typical functionalities
with parameters, ranges and limit values.
The FISCO model developed by the German PTB for hazardous locations permits connection of several devices to one common bus and
defines permissible limits for device and cable parameters.

weather exposure and mechanical damage.
The rugged molded enclosure can be wall mounted or fixed into a control panel. It can also be mounted at a post or pipe.
The device is designed for concentration determination of NaCl, HCl,
NaOH, H2SO4, HNO3.
4.2
The device can be easily replaced since the terminals are of a plug-in
design.
Technical features
Communication between measuring point and control room is via
PROFIBUS-PA. The data exchange (cyclic and acyclic) is performed
in accordance with the PROFIBUS-DP/V1 protocol.

Calibration
Calibration procedures (configurable)
- Calibration by specifying the cell factor of the sensor used (See
Page 31)
- Zero point calibration in air (See Page 32)
- Calibration with calibration solution (See Page 33)
- Input and adjustment of transfer ratio
(See Page 34)
The calibration is directly conducted on the
device.
Calibration via PROFIBUS-PA is not provided.
During calibration the Transmitter remains in
the Hold state for reasons of safety.
- Adjustment of temperature probe (See Page 35)
Information on calibration
Calibration is performed by entering the cell
factor or by determining the cell factor with a
known calibration solution under consideration of the temperature.
If the sensor is used for measurements with a
wall distance A < 110 mm, it must be calibrated with a similar wall distance.
A
All calibration procedures must be performed
by trained personnel.
When another sensor is used, its transfer ratio
must be entered before calibration (see “Input
and adjustment of transfer ratio” Pg. 34).
Incorrectly set parameters may go unnoticed,
but change the measuring properties.
E-30
Operation
In the case of an incorrect input ”Err” is displayed for approx. 3 sec. The incorrect parameters cannot be stored. Input must be
repeated.
For keypad functions see Pg. 24.
Calibration by input of cell factor
• Activate calibration
• End the Hold state
After 20 sec (for measured value stabilization) the device returns to
measuring mode.
English
The following steps must be executed:
• Enter mode code ”1100”
• Confirm entry
Welcome text 3 sec
• Enter cell factor
The lower display shows the conductivity
value.
A change in the cell factor also changes the
conductivity value.
When there has not been an entry for 6 sec,
the lower display alternately shows the conductivity and temperature value.
• Confirm cell factor
Operation
E-31
Zero point calibration in air
Zero point calibration is required when low
conductivity values are to be measured.
When there has not been an entry for 6 sec,
the lower display alternately shows the zerocorrected conductivity value and the temperature value.
Before you start calibration, remove the sensor from the process, clean it and dry it up.
• Confirm zero point
The following steps must be executed:
• End the Hold state
• Activate calibration
• Enter mode code ”1001”
• Confirm entry
Welcome text 3 sec
• Modify the zero point until the lower display
reads 0 µS.
If required, change the sign of the zero point.
E-32
Operation
After 20 sec (for measured value stabilization) the device returns to
measuring mode.
Calibration with calibration solution
During the calibration procedure the temperature must be kept constant.
Observe the response time of the temperature
probe.
When there has not been an entry for 6 sec,
the lower display alternately shows the conductivity and temperature value.
• Read the conductivity value corresponding
to the displayed temperature from the table
of the calibration solution used (see “Calibration solutions” Pg. 61)
• Change cell factor until the display shows
the conductivity value from the table
The following steps must be executed:
• Activate calibration
• Confirm cell factor
• Enter mode code ”1100”
• End the Hold state
After 20 sec (for measured value stabilization) the device returns to
measuring mode.
• Confirm entry
Welcome text 3 sec
• Immerse sensor in calibration solution
Operation
E-33
English
Be sure to use known calibration solutions and
the respective temperature-corrected conductivity values (see “Calibration solutions” Pg.
61).
Input and adjustment of transfer ratio
The Transmitter comes with a preset transfer ratio.
If another sensor is used, you must enter a different transfer ratio.
If you do not know the transfer ratio, it must be
determined in the test mode using a comparison resistor (see “Test mode” Pg. 44).
If the transfer ratio has been changed after a
cell factor calibration, this calibration must be
repeated.
The following steps must be executed:
• loop conductivity comparison resistor (simulator) through the sensor bore
• Adjust transfer ratio of sensor
Recommended resistance value for adjustment: R = 100 Ω.
• Modify the transfer ratio until the lower display shows the corresponding resistance
value (without considering the cell factor)
• Activate calibration
• Confirm transfer ratio
• Enter mode code ”1125”
• End the Hold state
After 20 sec (for measured value stabilization) the device returns to
measuring mode.
• Confirm entry
Welcome text 3 sec
• Enter transfer ratio of the sensor or

Operation
Adjustment of temperature probe
• End the Hold state
The following steps must be executed:
After 20 sec (for measured value stabilization) the device returns to

11.10 Glossary
Conductance
Conductance G [S] =1 / R [Ω]
Conductivity
Conductivity κ [S/cm] = G [S] · c [1/cm]
DTM (Device Type Manager)
Permits access to field device (acyclic services) via system with
FDT interface.
FDT (Field Device Tool)
Standardized interface for data exchange with field devices,
among others.
FISCO Model (Fieldbus Intrinsically Safe Concept)
Permits connection of several devices to a common bus line
and defines limit values for device and cable parameters. This
model developed by the German PTB assumes that only one
”active” device, i.e. the bus supply, is connected to the field bus.
All other devices are ”passive” with regard to the power supply
into the bus. Within the defined limits, the line characteristics
have no influence on the intrinsic safety.
GSD file (device database file)
Contains the communication features of slave devices. During
commissioning it is loaded in the process control system.
PROFIBUS-DP (decentralized peripherals)
Standardized specification (EN 50 170) of an open fieldbus
system for binary and analog signals of sensors and actuators.
It has been designed for high-speed data exchange at the device level.
E-68
Appendix
PROFIBUS-PA (process automation)
Open fieldbus standard for process automation. It makes use of
the transmission technology to IEC 1158-2 approved for operation in hazardous locations, which at the same time allows the
field devices to be powered over the bus.
SIMATIC-PDM
Tool developed by Siemens for projecting, configuring, commissioning and diagnostic of smart process analyzers. The
Transmitter device description (DD) is implemented in the SIMATIC-PDM.
Temperature coefficient
With temperature compensation activated, the measured value
is calculated to the value at the reference temperature using the
temperature coefficient.
Temperature compensation
Calculates the measured conductivity value for a reference
temperature.
