Please note the following:
• The device is approved for protection class II and is generally operated without a
protective ground connection.
• To guarantee measuring stability and functional safety, you must connect the outer
shield of the sensor cable:
– Inductive sensors: terminal "S"
– Conductive sensors: PE distributor rail
This is on the cover frame in the case of panel-mounted devices, and in the connection
compartment in the case of field devices. Ground this PE distributor rail or the ground
terminal directly on site wherever possible.
• Circuits "E" and "H" are not galvanically isolated from each other.

Setup 2 (temperature)
Temperature coefficient α indicates the change in the conductivity per degree of
temperature change:
k(T) = k(T0) . (1+ a . (T - T0))
A0009163
Where
κ(T) = conductivity at process temperature T
κ(T0) = conductivity at reference temperature T0
The temperature coefficient depends both on the chemical composition of the solution and
the temperature itself.
To determine the level of dependency, four different types of compensation can be selected
in the transmitter:
• Linear temperature compensation
• NaCl compensation
• NaCl ultrapure water compensation (neutral compensation)
• HCl ultrapure water compensation (acid compensation)
• Temperature compensation with table
Linear temperature compensation
The change between two temperature points is taken
to be constant, i.e. α = const. The α value can be edited
for linear compensation. The reference temperature
can be edited in the B7 field. The default setting is 25
°C.

Ultrapure water compensation (for conductive sensors)
For pure and ultrapure water, algorithms are saved in the transmitter that consider the
self-dissociation of ultra pure water and its strong temperature dependency. They are used
for conductivity levels of approx. 100 μS/cm.
Two types of compensation are available:
• NaCl ultrapure water compensation: this is optimized for pH-neutral contamination.
• HCl ultrapure water compensation: this is optimized for measuring the acid conductivity
downstream of a cation exchanger. It is also suitable for ammonia (NH3) and caustic
soda (NaOH).
• The ultrapure water compensation types always refer to a reference temperature of
25 °C (77 °F).
• The lowest conductivity displayed is the theoretical limit value of ultrapure water at
25 °C (77 °F) of 0.055 μS/cm.
Temperature compensation with table
For devices with the Plus Package, it is possible to enter a table with temperature
coefficients α as a function of the temperature. The following conductivity data of the
medium under measurement are required to use the alpha table function for temperature
compensation:
Value pairs comprising the temperature T and conductivity κ with:
• κ(T0) for the reference temperature T0
• κ(T) for the temperatures that occur in the process

Current input
For the "Current input" function group, you require a relay card with a current input which
is not available in the basic device version. With this function group, you can monitor
process parameters and use them for feedforward control. For this purpose, you must
connect the current output of an external measured variable (e.g. flowmeter) to the 4 to
20mA input of the transmitter. The following assignment applies:
Flow in main stream
Current signal in mA
Current input signal in %
Flowmeter start of measuring range
4
0
Flowmeter end of measuring range
20
100
Flow monitoring in the main stream
This arrangement is particularly practical if the sample flow through a flow assembly in an
open outlet is independent of the flow in the main stream.
This permits signaling of an alarm condition in the main stream (flow too low or has
completely stopped) and triggers dosing switch-off even if the medium flow is maintained
due to the method of installation.

You can optimize control on control systems with very short response times by measuring

Feedforward control is a multiplying function as illustrated in the figure below (example

Check
The CHECK function group is only available for devices with a Plus Package.
In the CHECK function group, you can select different monitoring functions for the
measurement.
Polarization detection (field P1)
In the case of conductive sensors, the effects of polarization in the boundary layer between
the sensor and medium restrict the measuring range. The transmitter can detect
polarization effects by using a smart signal analysis process. Error message E071 is
displayed.
Alarm threshold monitoring (fields P2 to P5)
You can use this function to monitor the measured value for permissible upper and lower
limits and trigger an alarm (error messages E154, E155).
PCS alarm (process check system), (fields P6 to P9)
AC (alternation check; sensor activity monitoring): The function AC (field P6) is used to
check measuring signals for deviations. An alarm (E152) is triggered if the measuring
signal remains constant within the space of one hour. The reason for such sensor behavior
can be contamination, cable open circuit or similar.
CC (controller check): You can monitor the controller activity with the CC function . This
function is primarily suited to batch operation and single-sided limit switches. A
malfunction of the controller is detected and reported thanks to freely adjustable
monitoring times (E156, E157).

Relay configuration
For the "RELAY" function group, you require a relay card which is not available in the basic
device version.
The following relay contacts can be selected and configured as desired (max. four contacts,
depending on options installed):
• Limit contactor for conductivity measured value: R2 (1)
• Limit contactor for temperature: R2 (2)
• PID controller: R2 (3)
• Timer for cleaning function: R2 (4)
• Chemoclean function: R2 (5)
• USP/EP: R2 (6) and R2 (7) (for Plus Package, only conductive sensors)
Limit contactor for conductivity measured value and temperature
The transmitter has different ways of assigning a relay contact. Switch-on and switch-off
points and pickup and dropout delays can be assigned to the limit contactor. In addition,
you can configure an alarm threshold to output an error message and to start a cleaning
function in conjunction with this.
These functions can be used both for the primary value and for temperature measurement.
Please refer to the switch states in → 29 for a clear illustration of the relay contact
states.
• When the measured values increase (maximum function), the relay contact is closed as
of t2 after the switch-on point (t1) has been exceeded and the pickup delay has elapsed
(t2-t1).
The alarm contact switches if the alarm threshold (t3) is reached and the alarm delay
(t4-t3) has also elapsed (errors E067 to E070).
• When the measured values decrease, the alarm contact is reset when the value falls
below the alarm threshold (t5) again, as is the relay contact (t7) after the dropout delay
(t7-t6).
• If the pickup and dropout delays are set to 0 s, the switch-on and switch-off points are
also switch points of the contacts.
The same settings can also be made for a minimum function in the same way as for the
maximum function.

P(ID) controller
You can define various controller functions for the transmitter. On the basis of the PID
controller, P, PI, PD and PID controllers can be implemented. For an optimum control
system, use the controller that best suits your application.
• P controller
Used for simple linear control purposes with small system deviations. Where major
changes are to be controlled, overshooting may occur. In addition, a lasting control
deviation must be expected.
• PI controller
Is used for control systems where overshooting is to be avoided and no lasting control
deviation should occur.
• PD controller
Is used for processes that require quick changes and where peaks must be corrected.
• PID controller
Is used for processes where a P, PI or PD controller does not control sufficiently.
Configuration options of the P(ID) controller
The following configuration options are available for a PID controller:
• Change control gain Kp (P influence)
• Set integral action time Tn (I influence)
• Set derivative action time Tv (D influence)
Basic load dosing (basic)
You can set a constant dosage amount (field R2311) with basic load dosing (field R231).
PID control plus basic load dosing
If you have selected this function (PID + Basic) in field R231, the PID-controlled dosage
amount does not drop below the basic load value entered in field R2311.

Commissioning
If you do not yet have any experience for setting the control parameters, set the values
that yield the greatest possible stability in the control circuit. Proceed as follows to
optimize the control circuit further:
• Increase the control gain Kp until the controlled variable just starts to overshoot.
• Reduce Kp slightly again and then reduce the integral action time Tn so that the shortest
possible correction time without overshooting is achieved.
• To reduce the response time of the controller, also set the derivative action time Tv.

Actuating signal outputs via contacts (R237 to R2310)
Each control contact outputs a cyclical signal whose intensity corresponds to the
controller's actuating value. A distinction is made according to the type of signal cycle:
• Pulse length modulation
The bigger the calculated manipulated variable is, the longer the contact affected
remains picked up. The period T can be set to be between 0.5 and 99 s (field R238).
Outputs with pulse length modulation are used to activate solenoid valves.
• Pulse frequency modulation
The bigger the calculated manipulated variable is, the higher the switching frequency of
the contact affected. The maximum switching frequency 1/T can be set to be between 60
and 180 min-1 (field R239). The on-time ton is constant. It depends on the set maximum
frequency and is approx. 0.5 s for 60 min-1 and approx. 170 ms for 180 min-1. 170 ms.
Outputs with pulse frequency modulation are used to activate directly controlled
solenoid dosing pumps.

Timer for cleaning function
This function includes a simple cleaning option. You can set the time interval after which
cleaning should start. Therefore you can only select a constant interval sequence.
Other cleaning functions are available for selection in conjunction with the Chemoclean
function (device version with four contacts required, see the "Chemoclean function"
section).
The timer and Chemoclean do not work independently of one another. While one of
the two functions is active, the other cannot be started.

Chemoclean function
Just like the timer function, Chemoclean can also be used to start a cleaning cycle.
However, Chemoclean also gives you the added option of defining various cleaning and
rinsing intervals and of dosing cleaning agent.
Therefore, it is possible to clean irregularly with different repeat cycles and to separately
set the cleaning times with post rinse times.
Please note the following:
• To use the Chemoclean function the transmitter has to be equipped with a designated
relay board (see product structure or chapter "accessories").
• The timer and Chemoclean are mutually dependent. While one of the two functions is
active, the other cannot be started.
• For the Chemoclean function, the relays 3 (water) and 4 (cleaner) are used.
• If the cleaning is prematurely aborted, a post rinse time always follows.
• If the setting is "Economy", cleaning only takes place with water.

The measurement is performed in the following steps:
• The transmitter determines the uncompensated conductivity and the water temperature.
• The transmitter rounds the temperature off to the nearest 5 °C and compares the
measured conductivity with the associated value in the table.
• If the measured value is larger than the value in the table, an alarm is triggered (E151).

The measurement is performed in the following steps:
• The transmitter determines the uncompensated conductivity and the water temperature.
• If the temperature is between two table entries, the limit value for the conductivity is
determined by interpolation of the two neighboring points.
• If the measured value is larger than the limit value, an alarm is triggered (E151).
Early warning: A USP early warning is also available. This is activated at a configurable
switch-on point (e.g. 80 % of USP/EP limit value). This means that the user is alerted to be
able to regenerate the plant in time. Der Voralarm wird in Feld R262 bzw. R272
eingestellt.
Please note the following:
• The device must be equipped with a relay card and the Plus Package to be able to use the
USP and EP function.
• To output an alarm, enable the fault-signaling contact or the error current in field F5 F7 (error code E151 and E153).
• The switch-off point of the pre-alarm is 1 % below of the switch-on point (R262 /
R272), related to the main limit value.
• The transmitter also uses the uncompensated values for the USP and EP function when
it displays temperature-compensated values.
• The limit value of 100 °C (212 °F) is used for temperatures over 100 °C (212 °F).

Concentration Measurement
The CONCENTRATION function group is only available for devices with a Plus Package.
The transmitter can convert from conductivity values to concentration values. For this
purpose, the operating mode is first set to concentration measurement (see field A1).
Afterwards, in the measuring device you must specify the basic data on the basis of which
the concentration is to be calculated. You require the conductivity characteristic curves of
the medium for this.
In the case of conductive sensors, the effects of polarization in the boundary layer between
the sensor and medium restrict the measuring range. The transmitter can detect
polarization effects by using a smart signal analysis process. Error message E071 is
displayed.
You can either refer to your data sheets for these characteristic curves or determine the
characteristic curves yourself.
1. Create samples of the medium in the concentrations that occur in the process.
2. Then measure the uncompensated conductivity of these samples at temperatures that
also occur in the process.
• For variable process temperatures:
If variable process temperatures are to be taken into consideration, you must
measure the conductivity for at least two temperatures (ideally the minimum and
maximum process temperature) for the samples created. The temperature values of
the various samples must be identical in each case. The temperatures must be at
least 0.5 °C apart.
At least two samples of different concentrations, taken at two different
temperatures in each case, are required as the transmitter needs at least four points
in the table (this must include the minimum and maximum concentration values).
• For constant process temperatures:
Measure the differently concentrated samples at this temperature. At least two
samples are required.
At the end you should have measuring data which resemble those shown in the following
figures.

• Variable process temperature:
Enter at least the four value triplets needed.
• Constant process temperature:
Enter at least the two value triplets needed.
Please note the following:
If the measured values of the process are outside the range of your sample values, this
considerably reduces the level of accuracy and the error message E078 or E079 will be
displayed. Therefore, take the limit values of your process into consideration when
determining the characteristic curves. Wird bei aufsteigender
If you enter an additional value triplet of 0 μS/cm and 0% for every temperature used
when the characteristic curve is increasing, you can work from the start of the measuring
range with sufficient accuracy and without an error message.
Enter the values in order of increasing concentration (see the following example).

Calibration
Use the CAL key to access the calibration function group.
Use this function group to calibrate and adjust the transmitter. The calibration can be
performed in two different ways:
• By measuring in a calibration solution of known conductivity.
• By entering the exact cell constant of the conductivity sensor.
Please note the following:
• During initial commissioning of inductive sensors, an air set is absolutely essential for
residual coupling compensation (from field C111) so that the measuring system can
return precise measurement data.
• If the calibration procedure is aborted by pressing the PLUS and MINUS keys at the same
time (return to C114, C126 or C136) or if the calibration is faulty, then the previous
calibration data are reinstated. A calibration error is indicated by “ERR” and the sensor
symbol flashes on the display.
Repeat calibration!
• For each calibration, the device automatically switches to hold (factory setting).
• On completion of the calibration, the device returns to the measurement mode. The
"hold" symbol appears on the display during the hold dwell period (field S4).
• Only items C121 to C126 are relevant for conductive sensors.

Trouble shooting instructions
The transmitter continuously monitors its functions itself. If an error occurs which the
device recognizes, this is indicated on the display. The error number is shown below the
display of the main measured value. If more than one error occurs, you can call these up
with the MINUS key.
Refer to the "System error messages" table for the possible error numbers and remedial
measures.
Should a malfunction occur without any transmitter error message, please refer to the
"Process-specific errors" or the "Device-specific errors" tables to localize and rectify the error.
These tables provide you with additional information on any spare parts required.

9.1.4
Simulation of inductive sensors for device testing
The inductive sensor cannot be simulated.
However, the overall system comprising the transmitter and inductive sensor can be tested
using equivalent resistors. Note the cell constant k (e.g. knominal = 1.98 cm-1 for CLS50,
knominal = 5.9 cm-1 for CLS52, knominal = 6.3 cm-1 for CLS54).
For accurate simulation, the actual cell constant used (visible in field C124) must be used
to calculate the display value.
The formula for calculation also depends on the type of sensor:
• CLS50 and CLS52: conductivity reading [mS/cm] = k[cm-1] ⋅1/R[kΩ]
• CLS54: conductivity reading [mS/cm] = k[cm-1] ⋅1/R[kΩ] ⋅ 1.21

Checking conductive sensors
• Measuring surface connection:
The measuring surfaces are directly connected to the connections of the sensor
connector. Check with ohmmeter for < 1 Ω.
• Measuring surface shunt:
A shunt is not permitted between the measuring surfaces. Check with ohmmeter for >
20 MΩ.
• Temperature sensor shunt:
A shunt is not permitted between the measuring surfaces and the temperature sensor.
Check with ohmmeter for > 20 MΩ.
• Temperature sensor:
See the sensor nameplate for information on the type of the temperature sensor being
used.
The sensor can be checked at the sensor connector with an ohmmeter:
– Pt 100 at 25 °C (77 °F) = 109.79 Ω
– Pt 1000 at 25 °C (77 °F) = 1097.9 Ω
– NTC 30 k at 25 °C (77 °F) = 30 kΩ
• Terminal:
For sensors with a terminal connection (CLS12/13) check the assignment of the
terminals to ensure they have not been inadvertently interchanged. Check the tightness
of the terminal screws.

9.1.6
Checking inductive sensors
The following applies to the CLS50, CLS52 and CLS54 sensors.
The sensor cables must be disconnected at the device or junction box for all tests described
here!
• Testing the transmitting and receiving coils:
Perform the measurement at the white and red coaxial cables, between the inner
conductor and shield in each case.
– Ohmic resistance
CLS50/52: approx. 0.5 to 2 Ω
CLS54: approx. 1 to 3 Ω
– Inductance approx. 180 to 500 mH (for 2 kHz, series circuit as equivalent circuit
diagram)
CLS50: approx. 250 to 450 mH
CLS52/54: approx. 180 to 550 mH
• Testing the coil shunt:
A shunt is not permitted between the two sensor coils (from red coax to white coax). The
measured resistance must be > 20 MΩ.
Test with the ohmmeter from the red coax cable to the white coax cable.
• Temperature sensor test:
Use the table in the "Simulation of conductive sensors for device testing" section to check
the Pt 100 / Pt 1000 in the sensor.
Measure between the green and white wires and between the green and yellow wires.
The resistance values must be identical.
• Temperature sensor shunt test:
Shunts are not permitted between the temperature sensor and the coils. Check with
ohmmeter for > 20 MΩ
Measure between the temperature sensor wires (green + white + yellow) and the coils
(red and white coax).
9.1.7
Assembly
Refer to the assembly operating manual for information on servicing and troubleshooting
the assembly. The assembly operating manual describes the procedure for mounting and
disassembling the assembly, replacing the sensors and seals, and contains information on
the material resistance properties, as well as on spare parts and accessories.
9.1.8
Connecting cables and junction boxes
• Use the methods described in chapters "Simulation of conductive/inductive sensors for
device test" to perform a quick functional check from the conductivity sensor (sensor
connector) to the measuring instrument via an extension. The easiest way to connect
resistor decades is with the "Conductivity testing adapter" service kit, order number:
51500629
• Check junction boxes for:
– Moisture (influence at low conductivity or for MΩ measurement, where necessary dry
box, replace seals, insert dehydrating bag)
– Correct connection of all lines
– Connection of the outer shields
– Tightness of the terminal screws

Repair
To assemble, carefully push the modules into the guide rails of the electronics box and let
them engage in the side box noses.
It is not possible to mount the modules incorrectly. Modules inserted in the electronics
box incorrectly are not operable since the ribbon cables cannot be connected.
Make sure the cover seals are intact to guarantee IP 65 ingress protection.

Replacing the central module
Generally, when a central module has been replaced, all data which can be changed
are set to the factory setting.
If possible, note the customized settings of the device, such as:
• Calibration data
• Current assignment, main parameter and temperature
• Relay function selections
• Limit value/controller settings
• Cleaning settings
• Monitoring functions
• Interface parameters
Proceed as described below if a central module is replaced:
1.
Disassemble the device as explained in the "Dismantling the panel-mounted
instrument" or "Dismantling the field instrument" section.
2.
Use the part number on the central module to check whether the new module has
the same part number as the previous module.
3.
Reassemble the device with the new module.
4.
Put the device back into operation and check the basic functions (e.g. measured value
and temperature display, operation via keyboard).
5.
Read the serial number (“ser-no.”) off the nameplate of the device (e.g.
6A345605G00) and enter this number in fields E115 (1st digit = year, one-digit (6
in the example)), E116 (2nd digit: month, one-digit (A in the example)), E117 (digits
3-6 cons. number, four-digit (3456 in the example)).
In the field E118, the complete number is displayed again so you can check it is
correct.
You can only enter the serial number for new modules with the serial number 0000.
This can only be done once! For this reason, make sure the number entered is correct
before you press ENTER to confirm!
If an incorrect code is entered, the additional functions are not enabled. An incorrect
serial number can only be corrected at the factory!
