Operation

Utilize the advantage of the effectively wear-free control with binary outputs versus acontrol system with relay. With pulse frequency modulation (PFM), it is possible to achieve
virtually continuous dosing using a dosing pump with higher input frequency.
1.

Connect the INS proximity switch of the CCA250 assembly to a digital input of the
DIO module (e.g. slot 6, port 1).

2.

In the software, configure a controller and as the source select the binary input(e.g.Binary input 1) to which the proximity switch is connected. (Menu/Additional
functions/Controllers/Controller 1/Controller enable = Binary input 1)

3.

Signal type: For the selected input, select the factory setting (Static signal).

4.

Connect the measured value of a flowmeter to the second input of the DIO module(e.g. slot 6, port 2).

5.

Signal type: for this input, select PFM . (Menu/Inputs/Binary input 6:2/Signal
type = PFM)

6.

Input variable: select the corresponding measured value (Flow rate).
 You can now use the input you have just configured as the disturbance variablefor your controller 1).

7.

Disturbance variable: in the controller menu, select the binary input to which you
have connected the flow measured value. (Menu/Additional functions/Controllers/
Controller 1/Disturbance variable/Source of data = Binary input 6:2 andMeasured value = PFM value)

8.

You can activate a dosing pump through PFM via a digital output of the DIO module.
Connect the pump to an output of the DIO module (e.g. slot 6, port 1) and select thefollowing settings in the menu: Menu/Outputs/Binary output 6:1/Signal type =PFM and Source of data = Controller 1.

Take the direction of action of your dosing into account. Select the correct parameter(Actuator type = Unipolar+ or Unipolar-).
You must make additional settings in the controller menu to fully customize the control tosuit your process conditions.

The cleaning trigger is transferred to another device via a binary output. This does
not have its own connected cleaning unit, but its sensors are installed in the medium
affected by cleaning the master and are set to hold by the trigger.

3.

The trigger is transferred via an additional binary output to another device, whose
connected sensors have their own cleaning units. The signal can be used tosimultaneously activate a self-cleaning with the master.

Interrupting the operation via an external signal
You can temporarily interrupt the automatic operation of the analyzer via an externalsignal at the "DIO" module. This can be useful if no sample is available in your process at
certain times, e.g. during a cleaning phase.
The following information is processed at the binary inputs or output at the binary
outputs:• Binary inputs:
Signal for process access: The analyzer can only perform activities that require sample(measurement, calibration, cleaning) when the signal is active. The time and thesequence of activities correspond to the settings in the setup. All activities that require
sample are delayed as long as the signal is inactive.
• Binary outputs:• Measurement active signal: Indicates that a measurement is currently running. The
signal is not active in the event of a calibration or cleaning.
• Sample required signal: The signal is active for a configurable time before every
activity that requires sample. This makes it possible to activate an external pump or adilution module, for example.

calibration or cleaning is due on the basis of the set time intervals: in this case, these
activities are performed first of all and then the measurement follows immediately
afterwards. If necessary, connect the Measurement active signal to a binary output toidentify when the measurement actually begins. If you do not require any moremeasurements once the first measurement is finished, you have to already disable the
Signal for process access during the active measurement.
The following information is processed at the binary inputs or output at the binary
outputs:• Binary inputs:
Signal for process access: The analyzer can only perform activities that require sample(measurement, calibration, cleaning) when the signal is active. The time and thesequence of activities correspond to the settings in the setup. All activities that require
sample are delayed as long as the signal is inactive.
• Binary outputs:• Measurement active signal: Indicates that a measurement is currently running. The
signal is not active in the event of a calibration or cleaning.
• Sample required signal: The signal is active for a configurable time before every
activity that requires sample. This makes it possible to activate an external pump or adilution module, for example.

Activating an external pump before every measurement
If you convey the sample to the analyzer using an external pump or an external sample
preparation system, you can use the Signal for sample request to switch on the external
devices for a limited time only when the analyzer requires sample. The signal becomes
active before every measurement, calibration and cleaning. You can configure how longthe signal should be active for. The start of the actual analyzer activity is delayed by this
time.

Outputting the controller manipulated variable via the current output
Unipolar+ Assign to the output to which an actuator that can increase the measured value
is connected. Unipolar- Assign to the output to which an actuator that can decrease themeasured 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 inboth). 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 thepossibility of outputting the bipolar manipulated variable y to one current output only
(split range).

Menu/Setup/Additional functions/Mathematical functions• MF1: Formula• Tracking = On
• Source A = Time switch 1• Source B = Time switch 2• Formula = 18.0 + 3*NUM(A) + 2*NUM(B)
Explanation: NUM converts the logical value to a numerical value and thus enables
multiplication.
• 3*NUM(A) results in the value 3.0 from 08:00 to 17:00 and 0.0 outside of this time
period.
• 2*NUM(B) results in the value 2.0 from 12:00 to 17:00 and 0.0 outside of this time
period.
The formula thus yields one of these analog values depending on the time: 18.0, 21.0 or
23.0. This analog value can be used as a set point for a temperature controller.
Example 2: Time-based condition
A pump should switch on (via a relay) for 10 minutes every 2 hours. This only applies if
the pH value is lower than 4.0.

The formula yields a logical value (TRUE or FALSE) and is thus suitable to trigger a relay

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 thecontrol 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 3 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 themanipulated 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, theproportional band Xp (Kp=1/Xp).

Process type

Selection• Inline• Batch‣ Decide what type of process best describes
your particular process.

Factory setting
InlineBatch 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 thesystem is stable. If the target value is overshot, a two-sided control system can compensate for this. In the caseof 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 andvolume of the medium flow can change at any time and the controller has to react to these changes on acontinuous basis. If the flow rate and medium remain constant, the manipulated variable can also assume afixed value once the process has settled. Since the control process is never "finished" here, this type of control isalso referred to as continuous control.
A mixture of both process types can often be found in practice: the semi‐batch process. Depending on the ratio
between the flow and the container volume, this arrangement behaves either like a batch process oran in-line process.

PID 2-sided

A 2‐sided controller can output a manipulated variable in the range from -100 % to +100 %, i. e. themanipulated variable is bipolar. The manipulated variable is positive if the controller should increase theprocess 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 bedecreased. The value for x is greater than the set point w.

In the case of "flowing medium" (in-line) controls, the flow rate may not be 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 thistype 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) disturbancevariable 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

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 shouldstop entirely (zn = 0).

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 isdetermined as soon as the turbines are started. The system excludes the initially highconductivity values resulting from the ingress of air.
• If carbon dioxide is regarded as non-corrosive, the live steam can be directed to theturbine 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.

• (1) There is flow
• (2) The volume flow is above a defined value• (3) The concentration of chlorine drops below a defined value

value of the chlorine concentration)

5.

Configure the relay output with the Formula mathematical function and connect thedosing 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 alimit switch in between in order to attenuate the output signal via a switch-on and switchoff delay.

• 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).

A diagnostic message appears on the display or via the fieldbus , measured values are notplausible, or you identify a fault.
1.

See the Diagnostics menu for 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" 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 Memosens, BA01245C) or "Device-specific errors" (→  117).

11.5.1

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 arecharacterized 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 themalfunction is to be found in the measuring point. Any controller 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, a shorter
operating life or lower accuracy levels. The cause of the problem is to be found outside
the measuring point.
• M = Maintenance required. Action must 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.

11.5.2

Adapting the diagnostic behavior

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

behavior.

2.

Select the diagnostics 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? (Failure 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

Selection• Maintenance (M)• Out of specification (S)• Function check (C)• Failure (F)You can deactivate or reactivate a diagnostic
message here.
Deactivating means:• No error message in the measuring mode
• No error current at the current output
Decide whether an error current should be
output at the current output if the diagnostic
message display is activated.
In the event of general device errors, the error
current is switched to all the current outputs. In
the event of channel-specific errors, the error
current is only switched to the current output inquestion.
The messages are divided into different error
categories in accordance with NAMUR NE 107.
Decide whether you want to change a status
signal assignment for your application.
