Menu structure

The configuration and calibration functionsare arranged in a menu structure by functiongroups.

The function groups are selected in the setupmode with the PLUS and MINUS keys. TheENTER key is used to move from one functionto the next within a function group. The PLUSand MINUS keys are used for option selectionand editing. Selections must be confirmed bypressing the ENTER key. This also moves thecursor to the next function.Pressing the PLUS and MINUS keys at thesame time terminates programming (return tomain menu).

Note:

• If a change is made but notconfirmed by pressing the ENTERkey, the previous setting isretained.

• See the appendix of theseoperating instructions for anoverview of the Liquisys MCLM 223 F menu structure.

HOLD function: »freezing« the outputs

The current output can be »frozen« in thesetup mode and during calibration, i.e. thelast current value (resp. the in field S3 definedvalue) is constantly output. The display showsthe »HOLD« message (see chapter 5.8, p. 34for hold settings).

• During HOLD in the automatic mode thecontacts will go to the idle position(if factory settings are active).

• At CC, timer and external HOLD HOLDalways is active. Adjustments in the fieldsS2 and S3 will be ignored.

• An alarm delay will be reset to »0«.• This function can also be activated

externally via the HOLD input(see connection diagram in Fig. 3.4,digital input 1).

• The manual HOLD (field S3) also remainsactive after a power failure.

PCS alarm (Process Check System)

This function is used to examine themeasuring signal for changes. If themeasuring signal is constant for a specificperiod of time (several measured values), analarm is issued. This type of sensor behaviourmay be caused by soiling, etc.

5.5 Relay configuration

The relay contacts in the Liquisys MCLM 223 F can be configured as required.Switch-on and switch-off points and pickupand dropout delays can be defined for thelimit contactor. Moreover, an alarm thresholdcan be set to issue an error message.

Please refer to Fig. 5.5 for a graphicrepresentation of the contact states of anyrelay and of the alarm contact.

When the measured value increases (maxfunction), the relay contact is closed at time t2when the switch-on point has been exceeded(t1) and the pickup delay (t2 – t1) has expired.When the alarm threshold (t3) is reached andthe alarm delay (t4 – t3) also has expired, thealarm contact is switched.

When the measured value decreases, thealarm contact is reopened when themeasured value drops below the alarmthreshold (t5), and the relay contact alsoopens (t7, after the dropout delay t7 – t6).When the pickup and dropout delays are setto 0 s, the switch-on and switch-off points areidentical to the contact switching points.The picture below shows the switching statusfor a minimum contact.

5.6 Temperature compensation

The temperature compensation needs onlyto be performed in the conductivity mode(selection of mode in field A1, selection oftemperature compensation in field B2).

The temperature coefficient α specifies therelative change in conductivity per degree oftemperature change. It depends on thechemical composition of the medium and thetemperature itself.

In order to compensate for this dependence,three different compensation types can beselected in the Liquisys M CLM 223 F.

Linear compensation

The change between two temperature pointsis considered to be constant, i.e. α = const.The α value can be edited for the linearcompensation type. The referencetemperature is 25 °C.

NaCl compensation

The NaCl compensation (according toIEC 60746) is based on a fixed nonlinearcurve that defines the relationship betweenthe temperature coefficient and thetemperature. This curve is used for lowerconcentrations of approx. 0.1 ... 5 % NaCl.

Temperature compensation with table

In order to use the alpha-table function fortemperature compensation, the followingconductivity data of the process medium tobe measured are required:

Value pairs of temperature T and conductivity κfor T0 = 25 °C and for temperatures occurringin the process.

For the temperatures relevant in your process,you calculate the α values using the followingformula (not to calculate an alpha value for25 °C would neither make sense nor couldyou edit a table with this value!):

In the measuring instrument, the T/α valuepairs received in this way are edited into thetable, and measurement can be started.

You can determine the temperaturecoefficient α with the help of chapter

5.7 Concentration measurement

The Liquisys M CLM 223 F can convert fromconductivity values to concentration values.For that purpose, the operating mode is set toconcentration measurement (s. field A1).

Subsequently, the basic data for thecalculation of concentration must be enteredinto the measuring instrument. The datarequired for the most common substances arealready stored in your instrument. In field K1,you can select one of these substances.

It is also possible to determine theconcentration of a sample that is not stored inthe instrument. In this case you need theconductivity characteristics of the medium. Ifthese data are not available in data sheets,then you can easily determine thecharacteristics by yourself: Prepare samples

of the medium in concentrations occurring inthe process. Measure the uncompensatedconductivity of these samples at temperaturesalso occurring in the process.

Variable process temperature:If these variations shall be taken into accountfor concentration measurement, then theconductivity of each prepared sample mustbe measured for at least two differenttemperatures (minimum and maximumtemperature of the process).

Constant process temperature:Measure the differently concentrated samplesat this process temperature.

Finally you should have received measuringdata looking as follows:

The characteristics received from themeasuring points must rise or fall strictlymonotonically in the range of processconditions. That means they must not haveeither maxima or minima, or ranges ofconstant behaviour. Curve types like inFig. 5.11 are therefore impermissible.

Value entry

In the fields K6 to K8, the three parameters(value triplet with conductivity, temperatureand concentration) are now entered for eachmeasured sample.

Variable process temperature:At least two samples, i.e. two differentconcentrations, are required. For each ofthese samples, values for at least twotemperatures (minimum distance 0.5 °C) mustbe entered. The temperature values of sampleswith different concentrations must be equal ineach case. This results in a minimum of fourvalue triplets.

Constant process temperature:At least two value triplets must be entered inthe instrument. The temperature values of theentered triplets must be equal.

Note:

If the conductivity or temperaturevalues measured during operationare out of the measuring rangedefined in the concentration table(s. Fig. 5.9 and 5.10), then theaccuracy falls off essentially, and theinstrument generates an alarmmessage. Therefore the processlimits should be taken into accountfor the calculation of characteristics.

If in case of rising characteristic anadditional value triplet with 0 µS/cmand 0% is entered, then operationwith sufficient accuracy and withouterror message is possible from thestart of measuring range.

Calibration of inner resistance

If you use a conductive sensor in higherconductivities (> 45 mS/cm) the sensor’sinner resistance should be determined.

Otherwise a measuring error of more than 1 %could occur in some cases.

When performing the following menu fieldsyou determine the inner resistance and storeit in the measuring transmitter. Theconductivity values will be compensated withthis value.

By use of inductive sensors the calibration isnot necessary.

Procedure:

• Switch off power supply• Uninstall panel-mounted instrument resp.

open field instrument.• Connect the test resistance (included in

delivery) with terminals 83/84.• Perform the menu fields S12-S14.

Note:

• The cable resistance is notconsidered.

• Do not use another than the testresistance you obtained with yourdelivery.

5.11 Calibration

This function group is used to calibrate thetransmitter. Two different types of calibrationare possible:

• Calibration by means of measurement of acalibration solution of a known conductivity.

• Calibration by entry of the exact cellconstant of the conductivity sensor.

Note:

• For conductive sensors, onlythe menu positions C121 toC126 are relevant.

• The instrument is automaticallyswitched to hold during calibration(factory setting).

Note:

• If the calibration procedure isaborted by pressing the PLUS andMINUS keys simultaneously(return to C114, C126 or C136) orif the calibration is faulty, then theprevious calibration data arereinstated. A calibration error isindicated by the “ERR” messageand flashing of the sensor symbolon the display. In this case, repeatcalibration!

• The end of calibration is followedby a return to the measuringmode. During the hold delay time(field S4), the hold symbol isdisplayed.

If you have enough conductivity data thetemperature coefficient can also bedetermined by using the formula on page 29.

Otherwise please follow the instructions below:

• Immerse the sensor in the medium(minimum distance from wall: 15 mm;concentration has to be in the process-typical range).

• Meter the uncompensated conductivity at25 °C and note down this value and theexact temperature.

• Then perform the menu »D« (see below).Important: use the medium andtemperature prevalent in your process.

• With the temperature and α values you canedit the alpha-table for temperaturecompensation (see menu fields T1-T7 onpage 30).

• Coatings containing protein (food industry)Use mixture of hydrochloric acid (0.5%)and pepsin (1%), then rinse thoroughly.

8.7.2 Simulation of conductive sensors for instrument test

A measuring instrument for conductiveconductivity is checked by replacing theprocess and temperature sensor withresistors. The accuracy of the simulationdepends on the accuracy of the resistors.

Refer to the table on the right for conductivity(cell constant k set to nominal valueaccording to column 2). Otherwise: display ofCD[mS/cm] = k ⋅ 1/R[kΩ].

Refer to the table below for temperature (notemperature offset set on Liquisys MCLM 223 F).Connect temperature equivalent resistanceusing three-wire arrangement!

• Use the “CD test adapter” service kit toconnect decade resistors to the connectorof a conductivity measuring cable in placeof a conductivity sensor.Order number: 51500629.

8.7.3 Simulation of inductive sensors for instrument test

An inductive sensor cannot be simulated byresistors.

However, the overall system comprising theCLM 223-IF and inductive sensor can bechecked using equivalent resistances. Notecell constant k (e.g. knominal = 2 forCLS 50, knominal = 5.9 for CLS 52).

For an accurate simulation, the actual cellconstant (can be read in field C124) is to beused to calculate the display value:display of CD[mS/cm] = k ⋅ 1/R[kΩ].

Reference values for simulation of CLS 50 at25 °C:

330 Ω 5.90 cm–1 17.88 mS/cm

3.3 kΩ 5.90 cm–1 1.788 mS/cm

• Performance of simulation:Pull a cable through the sensor openingand then connect, e.g. to a decade resistor.

8.7.4 Checking of conductive conductivity sensors

• Measuring surface connection:The measuring surfaces are connecteddirectly to the connections of the sensorconnector.Check with ohmmeter for < 1 Ω

• Measuring surface shunt:A shunt between the measuring surfaces isnot allowed.Check with ohmmeter for > 20 MΩ

• Temperature sensor shunt:A shunt between the measuring surfacesand temperature sensor is not allowed.Check with ohmmeter for > 20 MΩ.

• Temperature sensor:Refer to the sensor nameplate for thetemperature sensor type.The sensor can be checked at the sensorconnector with an ohmmeter:– Pt 100 at 25 °C = 109.79 Ω– Pt 1000 at 25 °C = 1097.9 Ω– NTC 10 k at 25 °C = 10 kΩ

• Connection:Check terminal wiring (interchanged?) andtightness of clamping screws in the case ofsensors with screw terminals (CLS 12/13).

8.7.5 Checking of inductive conductivity sensors

The following specifications apply to sensorsCLS 50 and CLS 52:

• Testing of transmitting and receiving coils(white and red coaxial cables, measure-ment between int. conductor and screen):– ohmic resistance approx. 0.5 ... 2 Ω– induct. approx. 260 ... 450 mH (at 2 kHz)

• Testing of coil shunt:A shunt between the coils (from coax redto coax white) is not allowed.Check with ohmmeter for > 20 MΩ

• Testing of temperature sensor:Use the table in chapter 8.7.2 to check thePt 100.The resistance values between the greenand white wires and between the greenand yellow wires should be identical.

• Testing of temperature sensor shunt:Shunts between the temperature sensor(green, white or yellow) and the coils (redor white coaxial cable) are not allowed.Check with ohmmeter for > 20 MΩ.

8.7.6 Checking of line extension and junction box

• Use the methods described in chapter8.8.2 or 8.8.3 to perform a quick functionalcheck from the sensor connector(conductive sensors) or from the sensor(inductive sensor) to the measuringinstrument.Decade resistors are best connected withthe “CD test adapter” service kit (ordernumber: 51500629).

• Check junction boxes for:– Moisture (influence in low conductivity

range; dry junction box, replace gaskets,use desiccant bag)

– Correct line connections– Outer screen connections– Tightness of clamping screws
