In accordance with Namur NE43, the linear
range is from 3.8 to 20.5 mA (4..20 mA) or
from 0 to 20.5 mA (0..20 mA). If the range is
exceeded or undershot, the current value stops
at the range limit and a diagnostic message (460
or 461) is output.
The function meets NAMUR NE43.
Set the current value that should be output at
the current outputs in the event of an error.
The value for Error current should be outside the measuring range. If you decided that your Current
 output
range = 0..20 mA you should set an error current between 20.1 and 23 mA. If the Current
output range = 4..20 mA you could also define a value < 4 mA as the error current.
The device allows an error current within the measuring range. In such instances pay attention to possible
affects this may have on your process.

Outputting the controller manipulated variable via the current output
Assign Unipolar+ to the output to which an actuator that can increase the measured value
is connected. Assign Unipolar- to the output to which an actuator that can decrease the
measured value is connected.
To output the manipulated variable of a two-sided controller, positive manipulated
variables and negative manipulated variables generally have to be output to different
actuators, as most actuators are able to influence the process in one direction only (not in
both). For this purpose, the instrument splits the bipolar manipulated variable y into two
unipolar manipulated variables, y+ and y‐.
Only the two unipolar manipulated variable parts are available for selection for outputting
to modulated relays. If outputting the values via a current output, you also have the
possibility of outputting the bipolar manipulated variable y to one current output only
(split range).

Operation
Outputting diagnostic messages via the relay
If a relay is defined as a diagnostic relay (Function = Diagnostics), it works in the "failsafe mode".
This means that the relay is always energized ("normally closed", n.c.) in the basic state if
an error is not present. In this way it can also indicate a drop in voltage, for example.
The alarm relay always works in the failsafe mode.
You can output two categories of diagnostic messages via the relay:
• Diagnostic messages from one of the 4 Namur classes →  111
• Diagnostic messages which you have individually assigned to the relay output
A message is individually assigned to the relay output at 2 specific points in the menu:
• Menu/Setup/General settings/Extended setup/Diagnostics settings/Diag. behavior
(device-specific messages)
• Menu/Setup/Inputs/<Sensor>/Extended setup/Diagnostics settings/Diag. behavior

– switching between different calibration datasets in the case of optical sensors
– external hold
– a cleaning interval to be triggered
– PID controller switch-on/switch-off, e.g. via the proximity switch of the CCA250
– the use of the input as an "analog input" for pulse-frequency modulation (PFM)
• Via a digital output signal
– diagnostic states, point level switches, or similar states transmitted statically (similar

The controller structure of the device comprises set point damping at the input to prevent
erratic changes in the manipulated variable if the set point changes. The difference
between the set point w and the controlled variable (measured value) X results in the
control deviation which is filtered by a neutral zone.
The neutral zone is used to suppress control deviations (e) that are too small. The control
deviation thus filtered is now fed to the actual PID controller which divides into three parts
based on the P (proportional), I (integral) and D (derivative) values (top-down). The
integral section (middle) also comprises an anti‐windup mechanism for limiting the
integrator. A low-pass filter is added to the D‐section to damp hard D‐terms in the
manipulated variable. The sum of the 3 sections results in the internal controller
manipulated variable which is limited according to the settings (for PID‐2s to ‐100% to
+100%).
The graphic does not illustrate a downstream filter for limiting the rate of change of the
manipulated variable (can be configured in the menu in Max y change rate).
In the menu do not configure the gain Kp. Instead configure the reciprocal value, the
proportional band Xp (Kp=1/Xp).

Make the following decisions when configuring a controller:
• (1) What type of process can your process be assigned to? → Process type
• (2) Should it be possible to influence the measured variable (controlled variable) in one
direction or in both directions? One-sided or two-sided controller, → Controller type
• (3) What should be the controlled variable (sensor, measured value)? → Controlled
variable
• (4) Do you have a disturbance variable that should be active at the controller output? →

– Neutral zone, → Xn
– Proportional band, → Xp
– Integral action time (I-value), → Tn

• (6) What should the controller do in the event of a hold (measured error, sensor
replacement, cleaning etc.)?
– Pause or continue with dosing? →Hold behavior/Manipulated Variable
– At the end of a hold, continue or restart the control loop (affects I‐value)? →Hold

• (7) How should the actuator be triggered?
– Unipolar+: Assign this setting to the output for an actuator which can increase the
measured value.

Factory setting
Inline
Batch process
The medium is in a closed system.
The task of the control system is to dose in such a way that the measured value (controlled variable) changes
from its start value to its target value. No more dosing is needed once the set point has been reached and the
system is stable. If the target value is overshot, a two-sided control system can compensate for this. In the case
of 2-sided batch control systems, a neutral zone is used/configured to suppress oscillations around the set
point.
In-line process
In an in-line process, the control system works with the medium flowing by in the process.
Here, the controller has the task of using the manipulated variable to set a mixture ratio between the medium
and dosing agent such that the resulting measured variable corresponds to the set point. The properties and
volume of the medium flow can change at any time and the controller has to react to these changes on a
continuous basis. If the flow rate and medium remain constant, the manipulated variable can also assume a
fixed value once the process has settled. Since the control process is never "finished" here, this type of control is
also referred to as continuous control.
mixture of both process types can often be found in practice: the semi‐batch process. Depending on the
 Aratio
between the flow and the container volume, this arrangement behaves either like a batch process or
an in-line process.

PID 2-sided
A 2‐sided controller can output a manipulated variable in the range from ‐100% to +100%, i.e. the manipulated
variable is bipolar. The manipulated variable is positive if the controller should increase the process value. In the
case of a pure P-controller, this means that the value of the controlled variable x is smaller than the set point w.
On the other hand, the manipulated variable is negative if the process value should be decreased. The value for
x is greater than the set point w.

With "flowing medium" (inline) controls, it can happen that the flow rate is non-constant. In some
circumstances, strong fluctuations are possible. In the case of a settled control system in which the flow rate is
suddenly halved, it is desirable that the dosed quantity from the controller is also directly halved. In order to
achieve this type of "flow-rate‐proportional" dosing, this task is not left to the I‐component of the controller, but
rather one enters the (to be measured) flow rate as disturbance variable z multiplicative at the controller
output.

Strictly speaking, feedforward control involves an open-loop control system, since its effect is not measured
directly. That means that the feed flow is directed exclusively forward. Hence the designation "feedforward
control."
For the additive feedforward control that is alternatively available in the device, the (standardized) disturbance
variable is added to the controller manipulated variable. This enables you to set up a type of variable base load
dosing.
The standardization of the disturbance variable is required both for multiplicative and for additive feedforward
control and is done using parameters Z0 (zero point) and Zp (proportional band): zn = (z ‐ z0)/zp

Example
Flowmeter with measuring range 0 to 200 m3/ h
The controller would currently dose 100% without feedforward control.
The feedforward control should be configured such that at z = 200m3/h, the controller still doses at 100% (zn =
1).
If the flow rate drops, the dosing rate should be reduced, and at a flow rate of less than 4 m3/h, dosing should
stop entirely (zn = 0).
→ Select the zero point z0 = 4 m3/h and the proportional band Zp= 196 m3/h.

The pneumatic retractable assembly, e.g. CPA87x, is activated by compressed air via a twoway valve. As a result, the assembly assumes either the "Measure" position (sensor in
medium) or the "Service" position (sensor in rinse chamber). Media such as water or
cleaning agents are supplied via valves or pumps. Here there are two states: 0 (= "off" or
"closed") and 1 (= "on" or "open").
The hardware required for "Chemoclean Plus", such as control valves, pumps,
compressed air supply, media supply etc., must be provided by the customer.

Degassed conductivity
Carbon dioxide from the air can be a contributing factor to the conductivity of a medium.
The degassed conductivity is the conductivity of the medium excluding the conductivity
caused by carbon dioxide.
Advantages of using degassed conductivity taking the example of a power station:
• The conductivity caused by corrosion products or contamination in the feed water is
determined as soon as the turbines are started. The system excludes the initially high
conductivity values resulting from the ingress of air.
• If carbon dioxide is regarded as non-corrosive, the live steam can be directed to the
turbine far earlier during startup.
• If the conductivity value increases during normal operation, it is possible to immediately
determine an ingress of coolant or air by calculating the degassed conductivity.

Cation exchanger capacity (optional, with activation code)
Cation exchangers are used to monitor the water/steam circuit for inorganic
contamination. The cation exchangers eliminate the disruptive influence of alkalizing
agents, such as ammonium hydroxide or caustic soda, which are added to the boiler
feedwater.
The service life of cation exchangers depends on:
• The type of alkalizing agent
• The concentration of the alkalizing agent
• The amount of contamination in the medium
• The capacity of the cation exchanger (efficiency of the resin)
To ensure the smooth operation of power stations, it is important to continuously monitor
the exchange column load. When a user-defined remaining capacity is reached, the
transmitter displays a diagnostic message so that the ion exchange column can be replaced
or regenerated in good time.

Example: 2-point chlorine regulator with volume flow monitoring
A relay output activates a dosing pump. The pump should switch on when the following 3
conditions are met:
• (1) There is flow
• (2) The volume flow is above a defined value
• (3) The concentration of chlorine drops below a defined value

Configure the mathematical function Formula : Source A = DIO binary input, Source
B = AI current input, Source C = input Disinfection.
 Formula:
A AND (B > 3) AND (C < 0.9)
(where 3 is the lower limit value of the volume flow and 0.9 is the lower limit
value of the chlorine concentration)
5.
Configure the relay output with the mathematical function Formula and connect the
dosing pump to the corresponding relay.
The pump is switched on if all 3 conditions are met. If one of the conditions is no longer
met, the pump is switched off again.
 Instead of outputting the result of the formula directly to a relay, you can also connect a
limit switch in between in order to attenuate the output signal via a switch-on and switchoff delay.
Example: Load-based control
The load - i.e. the product of the concentration and volume flow - is needed for the dosage
of precipitants, for instance.

Measuring range switching
A measuring range switching (MRS) configuration includes the following options for each
of the four binary input states:
• Operating mode (conductivity or concentration)
• Concentration table
• Temperature compensation
• Current output turndown
• Limit switch range
An MRS set is assigned to a channel and switched on. The measuring range configuration
selected via the binary inputs is now applied instead of the normal configuration of the
linked sensor channel. For current outputs and limit switches to be controlled by the MRS,
they must be linked to the MRS set, not to the measuring channel.
Current outputs and limit switches can be linked to an MRS set. This MRS set gives you the
measured value and the associated turn down (current outputs) or the range for limit
value monitoring (limit switches).
A limit switch connected to an MRS set always uses the Out of range checkmode.
Consequently, it switches when the value is outside the configured range.
If a current output or limit switch is connected to an MRS set, the turndown, monitoring
range and limit switch mode can no longer be configured manually. Therefore, these
options are hidden in the menus (current outputs and limit switch).

Diagnostic modules
Here you can configure a maximum of 8 individual diagnostic messages.
A diagnostic module has the following properties:
• The feed source can be configured like a binary output (relay, digital output).
• You can choose whether the diagnostic message should be output at a high level or low
level.
• You decide which error category (Namur class) should be assigned to the message.
• You can define a customized text to be output as the diagnostic message text.
In addition you can switch off the factory diagnostic code for limit switches. This allows
you to:
• Use the limit switch on a purely functional basis (without a message)
• Configure application-specific message texts
• Control diagnostic modules directly by a digital signal or via a limit switch output
(enables the use of switch-on/switch-off delay, for example).

Calibration
Calibration
• Sensors with Memosens protocol are calibrated at the factory.
• Users must decide whether the process conditions present require calibration during
initial commissioning.
• Additional calibration is not required in many standard applications.
• Calibrate the sensors at sensible intervals depending on the process.

Diagnostics and troubleshooting
12.1
General troubleshooting
The analyzer transmitter continuously monitors its functions itself.
If a diagnostic message occurs, the display alternates between the diagnostic message and
the measured value in the measuring mode.
The color of the display background changes to red if a diagnostic message for error
category "F" occurs.
12.1.1
Troubleshooting
A diagnostic message appears on the display or via the fieldbus, measured values are not
plausible, or you identify a fault.
1.
See the Diagnostics menu for the details on the diagnostic message.
 Follow the instructions to rectify the problem.
2.
If this does not help: search for the diagnostic message under "Overview of diagnostic
information" (→  113) in these Operating Instructions. Use the message number
as a search criterion. Ignore the letters indicating the Namur error category.
 Follow the troubleshooting instructions provided in the last column of the error
tables.
3.
If the measured values are implausible, the local display is faulty or you encounter
other problems, search for the faults under "Process errors without messages" (→
Operating Instructions for Memosens, BA01245C) or "Device-specific errors"
(→  110).
 Follow the recommended measures.
4.
Contact the Service Department if you cannot rectify the error yourself. Only cite the
error number.

Adapting the diagnostic information
12.5.1
Classification of diagnostic messages
In the DIAG/Diagnostics list menu you can find more detailed information on the current
diagnostic messages displayed.
In accordance with Namur specification NE 107, the diagnostic messages are characterized
by:
• Message number
• Error category (letter in front of the message number)
– F = (Failure) a malfunction has been detected
The measured value of the affected channel is no longer reliable. The cause of the
malfunction is to be found in the measuring point. Any control system connected
should be set to manual mode.
– C = (Function check), (no error)
Maintenance work is being performed on the device. Wait until the work has been
completed.
– S = (Out of specification), the measuring point is being operated outside its
specification
Operation is still possible. However, you run the risk of increased wear, shorter
operating life or lower measurement accuracy. The cause of the problem is to be found
outside the measuring point.
– M = (Maintenance required), action should be taken as soon as possible
The device still measures correctly. Immediate measures are not necessary. However,
proper maintenance efforts would prevent a possible malfunction in the future.
• Message text
If you contact the Service Department, please cite the message number only. Since you
can individually change the assignment of an error to an error category, the Service
Department cannot use this information.

Adapting the diagnostic behavior
All the diagnostic messages are assigned to specific error categories at the factory. Since
other settings might be preferred depending on the application, error categories and the
effect errors have on the measuring point can be configured individually. Furthermore,
every diagnostic message can be disabled.
Example
Diagnostic message 531 Logbook fullappears on the display. You want to change this
message so that an error is not shown on the display for example.

2.
Select the diagnostic message and press the navigator button.
3.
Decide: (a) Should the message be deactivated? (Diagnostics message = Off)
(b) Do you want to change the error category?(Status signal)
(c) Should an error current be output? (Error current = On)
(d) Do you want to trigger a cleaning program? (Cleaning program)
4.
Example: You deactivate the message.
 The message is no longer displayed. In the DIAG menu, the message appears as
Past message.

Maintenance
Effects on process and process control
‣ Take all the necessary precautions in time to ensure the operational safety and
reliability of the entire measuring point.
The maintenance of the measuring point comprises:
• Calibration
• Cleaning the controller, assembly and sensor
• Checking the cables and connections.
LWARNING
Process pressure and temperature, contamination, electrical voltage
Risk of serious or fatal injury
‣ If the sensor has to be removed during maintenance work, avoid hazards posed by
pressure, temperature and contamination.
Make
sure the device is de-energized before you open it.
‣
Power
can be supplied to switching contacts from separate circuits. De-energize these
‣
circuits before working on the terminals.
NOTICE
Electrostatic discharge (ESD)
Risk of damaging the electronic components
‣ Take personal protective measures to avoid ESD, such as discharging beforehand at PE
or permanent grounding with a wrist strap.
For
your own safety, only use genuine spare parts. With genuine parts, the function,
‣
accuracy and reliability are also ensured after maintenance work.
13.1
Cleaning
13.1.1 Controller

Maintenance
13.1.2
Digital sensors
LCAUTION
Cleaning not switched off during calibration or maintenance activities
Risk of injury due to medium or cleaning agent
‣ If a cleaning system is connected, switch if off before removing a sensor from the
medium.
‣ If you wish to check the cleaning function and have therefore not switched off the
cleaning system, please wear protective clothing, goggles and gloves or take other
appropriate measures.
Replacing the sensor while ensuring measuring point availability
If an error occurs or the maintenance schedule stipulates that the sensor has to be
replaced, use a new sensor, or a sensor that has been precalibrated in the laboratory.
• A sensor is calibrated in the laboratory under optimum external conditions, thereby
ensuring better quality of measurement.
• You must perform onsite calibration if you use a sensor that is not precalibrated.
1.
Remove the sensor that requires maintenance.
2.
Insert the new sensor.
 The sensor data are automatically accepted by the transmitter. A release code is
not required.
Measurement is resumed.
3.
Take the used sensor back to the laboratory.
 In the laboratory you can get the sensor ready for reuse while ensuring the
availability of the measuring point.
Prepare the sensor for reuse
1.
Clean the sensor.
 For this purpose, use the cleaning agent specified in the sensor manual.
2.
Inspect the sensor for cracks or other damage.
3.
If no damage is found, regenerate the sensor. Where necessary, store the sensor in a
regeneration solution (→ sensor manual).
4.
Recalibrate the sensor for reuse.
13.1.3
Assemblies
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.
