About this manual

About this manualThis manual gives a detailed account of all the configuration options in the "Setup" menu.
A description of the following menus is provided here:• Inputs– Input configuration– Split into separate sections based on the different types of sensor that can be connected
Some submenus are identical for all sensor types.
These submenus are repeated in each input-specific section to make sure you can findthe information you need quickly and easily.
• Outputs– Output configuration– Split into separate sections based on the different output types• Sampling programs– Creating sampling programs– Configuring different types of programs• Additional functions– Settings for the alarm sensor– Cleaning program configuration• Data management– Firmware updates– Saving and loading configurations

Error current

0.0 to 23.0 mA
Factory setting
21.5 mA

In accordance with Namur NE43, the linear range isfrom 3.8 to 20.5 mA (Current output
range="4 to 20 mA") or from 0 to 20.5 mA (Current
output range="0 to 20 mA"). If the range is exceeded orundershot, the current value stops at the range limit anda diagnostics message (460 or 461) is output.
You must select the "4 to 20 mA" range for HART communication.
The function meets NAMUR NE43.
Set the current value that should be output at thecurrent 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 to 20 mA", you should set an error current between 20.1 and 23 mA. If the Current output range= "4 to 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.

The system only displays the errors that are present
longer than the set delay time. This makes it possible tosuppress error messages that only occur briefly and arecaused by normal process-specific fluctuations.
You can enable an immediate, general hold here. The
function has the same effect as the "HOLD" soft key inthe measuring screens.

The Dynamic Host Configuration Protocol (DHCP) makes
it possible to assign the network configuration to clients
via a server. With DHCP, it is possible to automaticallyintegrate the device into an existing network without
the need for manual configuration. Normally, the clientneed only be configured for automatic retrieval of the IP
addresses. During startup, the IP address, the netmask
and the gateway are retrieved from a DHCP server.
An IP address is an address in computer networks which
are based on the Internet protocol (IP).

On the basis of the IP address of a device, the netmask
specifies which IP addresses this device searches for in
its own network and which addresses it could access inother networks via a router. It therefore divides the IP
address into a network part (network prefix) and a
device part. The network part must be identical for all
devices in the individual network, and the device part
must be different for every device within the network.
A gateway (protocol converter) enables communication
between networks that are based on completely
different protocols.

Thegraphic below explains the various ways sampling can be controlled on the basis of a flow
curve:
a. Flow curveb. Time-paced sampling
A constant sampling volume (e.g. 50 ml) is taken at
steady intervals (e.g. every 5 min).
c. Flow-paced sampling
A constant sampling volume is taken at variableintervals (depending on the inflow volume).
d. Time/flow-paced sampling
A variable sampling volume (the sampling volume
depends on the inflow) is taken at steady time intervals (e.g. every 10 min).
e. Event-controlled sampling
Sampling is triggered by an event (e.g. pH limit
value). Sampling can be time-paced, flow-paced, ortime/flow-paced, or single samples can be taken.

Liquistation CSF48

The following table explains the various types of sampling using specific examples.
Type of sampling

ExampleInfo

Time-paced• Sampling interval: 5 min• Sampling volume: 50 ml• Bottle change mode: 2 hThis type of sampling remains constant overtime and does not take changes in flow or polluting load into account. It is possible to take arepresentative sample if the intervals are brief(e.g. 5 min).

With this setting, a 50 ml sample is taken every
5 minutes. 12 samples are thus taken every
hour. Each bottle is filled over a period of 2hours. This results in a total sampling volume of
24 samples per bottles x 50 ml = 1200 ml.
Flow-paced

Controlled via current input• Signal: 0 to 20 mA = 0 to 600 m³/h
• Sampling volume: 50 ml• Sampling interval: 20 m³• Bottle change mode: 2 h
If 20 mA = 600 m³/h, a sample is taken every 2
minutes (smallest sampling interval with maximum flow). The total number of samples
amounts to 60 samples per bottle. With a flowof 300 m³/h, a sample is taken every 4 minutes.
Controlled via binary input• Signal pulse: 5 m³
• Sampling volume: 50 ml• Sampling interval: 20 m³• Bottle change mode: 2 h
The pulses are scaled at the flowmeter. By multiplying the pulses at the sampling interval, theshortest sampling interval at the maximum
pulse frequency can be set.
Example: Given a maximum flow of 600 m³/h,
the pulse frequency at 5 m³ is 120 pulses/h or 2
pulses/min. With a sampling interval of 20 m³,
sampling takes place after 4 pulses = 2 minutes.

34• The current inputs can be configured for thecurrent range of 0 to 20 mA or 4 to 20 mA.
• The binary inputs require power (24 V DC)
for floating contacts.
In the case of flow-paced sampling, the sampling interval is calculated on the basis of thevolume flow. The same sampling volume is takeat variable intervals.
Advantage:
Good, representative results in the event ofminor fluctuations in flow.
Disadvantage:
Longer intervals when the level of water is low
mean that malfunctions cannot be detected.

Liquistation CSF48

Programming

Type of sampling

ExampleInfo

Time/flow-paced(only possible withperistaltic pump)Controlled via current input• Signal: 0 to 20 mA• Sampling interval: 10 min• Sampling volume: variable

Samples are taken at set intervals with a variable sampling volume. The sampling volume iscalculated from the flow rate. More volume isgrabbed when the flow is high than when it islow. Since the flow normally fluctuates and the
maximum flow is only rarely a constant variable,
the sampling volume transferred to the container will depend on the daily average.

The maximum sampling volume is defined at
the maximum flow rate.
Example: The maximum flow rate at 20 mA at
the current input is 160 l/s, and the maximum
sampling volume is 200 ml. When transferring
samples into a 30l mixed sample container, 144
samples are taken per day with a maximum
sampling volume of 28.8 l. With a flow rate of
80 l/s, a sampling volume of only 100 ml would
be grabbed, and a sampling volume of 50 ml
would be grabbed at a flow rate of 40 l/s.
The sampling volume is always calculated basedon the flow.
Controlled via binary input• Binary input (pulse per flow unit)• Sampling interval: 10 min• Sampling volume: variable
The sampling volume is defined for a flow pulse,
e.g.: 1 pulse is 20 ml. For instance, if 5 flow pulses are counted between the sampling intervals,
this results in a sampling volume of 5 x 20 =100 ml, and a volume of 8 x 20 = 160 ml for 8
pulses.
If a binary input is used for time/flow-paced
sampling, the sampling volume is calculated per
sample as a percentage of the specified sampling volume.
Event

Event-based sampling is controlled via the current input, binary input and/or sensor input.
The subprogram created waits to be activated byan event that can consist of up to 3 individual
events. Every possible condition can be createdusing logical "and" / "or" links. For example, theinformation from a flowmeter connected to thecurrent input can be linked to a rain gage and a
pH sensor signal connected to the binary input.
An event is defined as limit value violation(exceeded or undershot), range monitoring
within or outside a range, or a rate of change.
Users can decide whether additional sampling isstarted when the event starts and/or ends. For
the duration of the event, users can choose fromtime-paced, flow-paced or time/flow-paced
sampling, or can take single samples, use a sampling table or the external control system.

Advantage:
Very good, representative sampling given large
fluctuations in the flow and constant time intervals.
Disadvantage:
Too little sampling volume is made available foranalysis when the flow is low.
Advantage with current input:
For the sampling interval, either the current
flow rate or the average value between the lastand current flow rate is used to calculate theexact sampling volume (depending on the presetting).
Disadvantage with binary input:
For the sampling interval, the pulses counted
since the last sampling are multiplied by a
volume. If this is too high - e.g. 100 ml - thecomposition of the sample is not representative
for analysis.

The sampler waits for an event. This event takes
place via internal sensor signal processing or via
devices connected externally. As bottle assignment is possible when using several bottles,
events can be assigned to individual bottles. A
maximum of 24 subprograms can be started
simultaneously and assigned to individual bottles.

4.1.1 Bottle synchronization
The bottle synchronization setting is possible with all types of program. In addition, bottle synchronization can be switched via an external signal.
Bottle synchronization is only possible with a bottle change after a specific time and not with abottle change after a number of samples.
Specific bottles can be assigned specific filling times with the bottle synchronization function.
For example, bottle 1 is to be filled from midnight to 2 a.m., bottle 2 from 2 a.m. to 4 a.m. etc..
The following options are available for this:• None: The time of sampling and bottle change are not synchronized.
• 1. bottle change time: Sampling starts with the first bottle. The changeover to the next bottles
is synchronized. For example, a time of 2 hours was set for bottle changeover, and 00:00 was
set for the synchronization. If the program is started at 5:23 a.m., for example, bottle 1 is initially filled. The system switches for the first time to bottle 2 at midnight (00:00), to bottle 3
at 2 a.m. etc.
• 1. Time of change + bottle number: A specific filling time is assigned to every bottle. For
example, midnight to 2 a.m. for bottle 1; 2 a.m. to 4 a.m. for bottle 2; 4 a.m. to 6 a.m. for bottle
3 etc. If the program is started at 10 a.m., for example, the device starts filling bottle 6.
It is also possible to start synchronization on a specific day of the week.
For example, a time of 24 hours was set for bottle changeover, Monday 00:00 was the time
set for synchronization, and Tuesday 8 a.m. was set for starting the program. The system fills
bottle 2 until 00:00 on Wednesday and then switches to bottle 3.
• External signal: The system changes to the next bottle when an external signal is received.
The external signal first has to be configured via the binary input. The binary input can thenbe selected as the source.

Programming

Program type: BasicWith the Basic program type, you can create simple sampling programs quickly based on time,
volume and flow. In the case of volume- and flow-controlled sampling, the inputs have to be
configured appropriately beforehand. If you want to create a program and use it immediately,
you have to check the configuration of the sampler before programming. You can make the settings under "Menu/Setup/General settings/Sampling": e.g. the bottle configuration, and the bottle volume, as well as the correct dosing volume for the device version with a vacuum pump. The
dosing volume setting makes it possible to correctly calculate the level in the bottle and is a reliable way of preventing the bottles from being overfilled.
You can go to the Setup program either via the overview under "Select sampling program"or via the path "Menu/Setup/Sampling programs".

In the power station industry, for example, it is advantageous to use the degassed conductivity:• The percentage of conductivity caused by corrosion products or fouling in the feed water canbe determined as early as when 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 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.

Information on sensors with the Memosens protocol

Information on sensors with the Memosens protocol

The options described below are only available on devices with a least one Memosens input.
Sensors with the Memosens protocol have integrated electronics that save calibration data andother information. The sensor data are automatically communicated to the transmitter when
the sensor is connected and are used to calculate the measured value.
Data digital sensors save include:• Manufacturer data
– Serial number– Order code
– Date of manufacture• Calibration data
– Date of calibration– Calibration values– Number of calibrations– Serial number of the transmitter used to perform the last calibration• Operating data
– Date of initial commissioning– Hours of operation under extreme operating conditions– Sensor monitoring data
The specific data that are recorded and communicated to the transmitter depend on thesensor used. Differences can also occur within a sensor type.
This causes different menu items to be displayed or hidden depending on the sensor connected.
Pay attention to specific information in this manual.
Example:The amperometric oxygen sensor COS51D cannot be sterilized. For this reason, you will not beable to define limit values for sterilization in the diagnostics settings for this sensor. On theother hand, these menu items are displayed for a sterilizable amperometric sensor, such as
COS22D.

Buffer recognition (only pH or combi sensor)
Automatic buffer recognition
To ensure a buffer is detected correctly, the measuring signal may deviate by a maximum of 30
mV from the value stored in the buffer table. This is approx. 0.5 pH at a temperature of 25˚C. If
both buffers - 9.00 and 9.20 - were used, this would cause the signal intervals to overlap andbuffer recognition would not work. For this reason, the device would recognize a buffer with a
pH of 9.00 as a pH of 9.20. --> Do not use the buffer with a pH of 9.00 for automatic buffer
recognition.

Displays the current value. Only changes with acalibration.

In confined installation conditions, the wall affects conductivity measurement in the liquid.
The installation factor compensates for this effect. The transmitter corrects the cell constant by
multiplying by the installation factor.
The size of the installation factor depends on the diameter and the conductivity of the pipe
nozzle, as well as the distance between the sensor and the wall.
If there is a sufficient distance between the wall and the sensor (a > 15 mm (0.59"), from
DN 80), the installation factor f does not have to be taken into consideration (f = 1.00).
If distances from the wall are smaller, the installation factor is bigger for electrically insulating
pipes (f >1), and smaller for electrically conductive pipes (f < 1).
It can be measured using calibration solutions, or a close approximation determined from thefollowing diagram.

Electrolyte counter
The electrolyte consumption is calculated on the basis of the amount of charge that penetrates
the sensor diaphragm.
The following applies for the sensor CCS142D:
Half the chloride would be consumed and the entire dihydrogen phosphate would be converted
to monohydrogen phosphate in an electrolyte filling (4 ml) at 20 000 000 μAs (=20 As). This
would render the electrolyte and the sensor unusable.
With a view to predictive maintenance, you should replace the electrolyte at 10 000 000 μAs,
and preferably at 5 000 000 μAs. 25%-50% of the dihydrogen phosphate is then consumed.
The calculation presumes that the buffer of the electrolyte is only changed by theelectrochemical conversion of hypochlorous acid. It does not take into account the penetrationof acids or bases into the sensor.
Depending on the application it can be necessary to change the electrolyte before a charge of
5 As is reached.

factory calibration is based on a three-point calibration of a reference sample.
The factory calibration cannot be deleted and can be retrieved at any time. All other calibrations
performed as customer calibrations - are referenced to this factory calibration.
Calibration data records are saved under an individual name. You can add your own data

17.3.3 Compensation
Depending on the selectivity of the ion-selective electrode vis-à-vis other ions (interferenceions), and the concentration of these ions, such ions could also be interpreted as part of themeasuring signal and thus cause measuring errors.
When measuring in wastewater, the potassium ion - which is chemically similar to theammonium ion - can cause higher measured values.
The measured values for nitrate can be too high due to high concentrations of chloride.
To reduce measuring errors resulting from such cross-interference, the concentration of thepotassium or chloride interference ion can be measured and compensated for with a suitable
additional electrode.
For the pH, chloride and the potassium electrode, you can only configure an offset. The settings for compensation of the effect of interference ions are available only for ammonium
and nitrate.
