The sensor is connected via a multiple-core,special screened cable which is completelyterminated and permanently connected. Usea junction box, e.g. VBM to extend themeasuring cable. Termination instructions aresupplied with the measuring cables.

Note:

• Protect cable ends and terminalsagainst moisture to preventinaccurate measurement!

• For further information on cablesand junction boxes refer to chap.9 Accessories.

4.5.2 Access codes

All instrument access codes are fixed, i.e. they cannot be modified. When the instrumentrequests the access codes, it recognises the difference between codes (cf. Fig. 5.3):

• CAL key + Code 22: Access to Calibrationand Offset menus.

• ENTER key + Code 22: Access to theConfiguration menus, allowingconfiguration and user-specific settings.

• PLUS + ENTER keys + Code 9999:Locks the keypad.

• CAL + MINUS keys + Code 0:Unlocks the keypad.

• CAL or ENTER key + any Code: Accessto Read mode, i.e. all settings can be readbut not changed.

4.5.3 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.The ENTER key is used to move from onefunction to the next within a function group.The PLUS and MINUS keys are used foroption selection and editing. Selections mustbe confirmed by pressing the ENTER key.This also moves the cursor to the nextfunction.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.

4.5.4 Hold function: “Freezes” the outputs

The current output is “frozen” in the setup mode and during calibration, i.e. the last currentvalue is constantly output. HOLD appears on the display. In case of steady control (4... 20 mA)on current output 2, it is set to 0/4 mA during Hold.

Note:

• Hold settings can be found inchap. 5.6, function S2.

• During automatic operation, allcontacts will go to their normalpositions.

• An active hold has priority over allother automatic functions.

• With every hold, the I componentof the controller is set to zero.

• A possibly accumulated alarmdelay is reset to “0".

• The hold function can also beactivated externally via the holdinput (see connection diagram inFig. 3.10; digital input 1).

• The manual hold (field S3) remainsactive even after a power failure.

5.3 Current input

This function group offers two independent application solutions, provided that the currentoutput of an external measured quantity, e.g. flow meter, is connected to the 4 … 20 mA inputof Liquisys M CUM 223 / 253. The following assignments then apply:

5.3.1 Monitoring the flow rate in the main stream

This arrangement is highly practical when the sample stream flowing through the flow assemblyis totally independent of the flow rate in the main stream. This permits the signalling of an alarmstate in the main stream (flow rate too low or totally stopped) and trigger a dosing switch-off,even if the measuring water stream is retained due to the installation configuration.

5.3.2 Feedforward control to PID controller

In processes with very short response times it may be practical to apply the flow rate to thecontroller, if the flow rate fluctuates, in order to optimise the control process.

5.4 Current outputs

The function group CURRENT OUTPUT is used to configure the individual outputs. Either alinear (O3 (1)) or, in conjunction with the Plus package, a user-defined current outputcharacteristic (O3 (3)) can be entered. Furthermore, a current output value can be simulated tocheck the current outputs (O3 ( 2)).The controller set value in field R 237 can be output via current output 2, if available.

The distance ∆ signal between two table value pairs must exceed:

• 0.005 FNU / NTU / ppm / mg/l / %• 0.05 g/l• Temperature: 0.25 °C

First enter the current output configuration you require in the following blank table. Ensure therequired minimum distance by calculating the resulting signal distance per mA. Then enter theresult in the instrument.

5.5.2 Check

The function group CHECK is only accessible for instruments equipped with the Plus packet.

PCS alarm (Process Check System)

This function is used to examine the measuring signal for deviations. If the measuring signal isconstant for a specific period of time (several measured values), an alarm is issued. This type ofsensor behaviour may be caused by soiling or similar.

Note:

A current PCS alarm is automaticallydeleted as soon as the sensor signalchanges.

6.1 Relay contact configuration

The function group RELAYS is only accessible for instruments equipped with the Plus packet.

The relay contacts described below can be selected and configured as required (max. fourcontacts depending on options installed):

• Limit contactor for measured turbidity value R2 (1)• Limit contactor for temperature: R2 (2)• P(ID) controller: R2 (3)• Timer for cleaning function: R2 (4)• ChemoClean function R2 (5)

6.1.1 Limit contactor for measured turbidity value and temperature

The relay contacts in the Liquisys M can beassigned different functions.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 and tostart a cleaning function.These functions may be used for turbidity andtemperature measurement.

Please refer to Fig. 5.5 for a graphicrepresentation of the alarm contact states ofany relay or alarm contact.

When the measured value increases (max.function), 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 reset when the measuredvalue drops below the alarm threshold (t5).The relay contact is also reset (t7, after thedropout 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.Settings analogous to the max function canalso be made for a min function.

6.1.2 P(ID) controller

The Liquisys M supports the definition of various controller functions. On the basis of the PIDcontroller, P, PI, PD and PID controllers can be implemented. To obtain the best controlresponse, use the controller best suited to the application in question.

• P controller: Used for simple linear control purposes with small system deviations. Wheremajor changes are to be controlled, overshooting may occur. A control offset is to beexpected.

• PI controller: Used for processes where overshooting is to be avoided and permanentoffsets are not allowed.

• PD controller: Used for processes that require quick response and where peaks are to becorrected.

• PID controller: Used for processes for which the type of control provided by a P, PI or PDcontroller is inadequate.

Adjustments of P(ID) controller

Three parameters can be adjusted in the case of a PID controller:

• the control gain Kp (P influence)• the integral action time Tn (I influence)• the derivative action time Tv (D influence)

Start-up

If there are no empirical values available for setting the control parameters, use values thatprovide the greatest possible stability of the control loop. To optimise the control loop further:

• Increase the control gain Kp until the control variable just starts to overswing.• Decrease Kp again slightly and shorten the integral action time Tn to achieve the shortest

possible correction time without overswing.• In order to shorten the response time of the controller, you also have to set the derivative

action time Tv.

Checking and fine tuning of parameter settings using a recorder

Actuating signal outputs (R237 ... R2310)

The control contact in question outputs a switched signal. The intensity of this signal isproportional to the controller’s output. A distinction is made according to the type of signalclock:

• Pulse length modulationThe greater the calculated control output,the longer the contact in question remainspicked up. The period can be adjustedbetween 0.5 and 99 s. Pulse-lengthmodulated outputs are used to controlsolenoid valves.

• Pulse frequency modulationThe greater the calculated control output,the higher the switching frequency of thecontact. The maximum switchingfrequency 1/T can be adjusted between 60and 180 min–1. The ON period tON isconstant. Pulse frequency-modulatedoutputs are intended for controllingsolenoid-operated metering pump s.

Control characteristic for direct and inverse control action

Field R236 offers two control characteristics for selection which have the effects shown in thefollowing diagram.

6.1.3 Timer for cleaning function

This function can be used to implement asimple cleaning routine. The user can specifya time interval after which cleaning is to start;i.e. only constant intervals can be defined.

There are other cleaning functions inconjunction with the ChemoClean function(version with four contacts, see chap. 5.5.4).

Note:

The timer and ChemoClean do notwork independently of each other.Whilst one of the functions is active,the other cannot be started.

6.1.4 ChemoClean function

Just like the timer function, ChemoClean canalso be used to start a cleaning cycle.However, ChemoClean supports differentcleaning and rinse intervals.

Thus, irregular cleaning with different repeatcycles is possible, and cleaning times withpost-rinse times can be individually defined.

Note:

• The ChemoClean function is onlyavailable with relays 3 (water) and4 (cleaner).

• Abortion of the cleaning process isalways followed by a post-rinsetime.

• When “Economy” is selected,cleaning is performed with wateronly.

5.10 CalibrationThis function group is used to calibrate thetransmitter.

Calibration options

• Three-point calibration• Correction of an existing calibration with

the laboratory value• Modification of individual values of the

three-point calibration• Installation adjustment• One-point calibration

Note:

• If the calibration procedure isaborted by pressing the PLUS andMINUS keys at the same time(return to C115, C123, C135, C143or C153) or if the calibration isfaulty, then the previouscalibration data are reinstated. Acalibration error is indicated by the“ERR” message and flashing ofthe electrode symbol on thedisplay. Repeat calibration!

• After calibration, the systemreturns to Measuring mode.During the hold delay time (FieldS4), the Hold symbol appears inthe display.

Overview of calibration

The calibration of the meeasuring chain isthree-point calibration, i.e., a turbidityascertained from three samples or from aknown solids content of the medium is usedto calculate the complete calibrationcharacteristic of the measuring chain for themedium of the transmitter CUM 223 / 253.

It is wise to undertake calibration in theturbidity or solids concentration range inwhich you want to make measurements.

To simplify the three-point calibration, wesuggest to produce three samples requiredfor calibration by thinning a medium sample.Usually, very good calibration results areachieved with the concentration graduations10 %, 33 % and 100 % of the originalconcentration. The transmitter suggests this

concentration graduation for the three-pointcalibration. This method also has theadvantage the only the turbidity or solidsconcentration value of the original laboratorysample need be defined exactly.

Note:

In particular, the concentrationgraduation must changed forsamples with a very highconcentration or a very dark colour.Very good results are achieved witha graduation of 3%, 10% and 100%.The original sample must also bemeasured in the laboratory forresults correction after the laboratorymeasurement.

However, this procedure is not a mandatory prerequisite for calibration. You can also take threedifferent samples of the process medium and determine their turbidity or solids concentrationvalues. The following conditions must be met:

• Calibration must be carried out relating to the concentration in increasing order.• The three samples must differ by at least 10 % relating to the measured value.• At higher solids concentrations, clean water is sufficient as a zero solution.

Note:

• Sludge samples tend to sediment.It is therefore important to stir thesample well, possible even duringcalibration. When stirring, avoidforming a cyclone by not stirring ina circle.

• The characteristic calculatedduring the three-point calibrationis stored in the currently selectedcalibration data record (see FieldB4). If you select theunchangeable (read only)calibration data record no. 1, nocalibration is possible.

• If the calculated relativecalibration results deviate by morethan –50 % / +100 % from thereference value 100 %, a warningis output (E084). The calibrationcan be transferred nonetheless.

• If the calculated results lie outsidethe permitted limits, then thecalibration error is displayed(E045). The calibration is nottransferred.

• The gas bubble barrier in field B9has to be 3.0 during calibration.

Management of the transmitter calibration data records

There are three calibration data records available for each application (FNU, NTU, ppm, g/l, %).Of these three data records (sample characteristics), one has been permanently programmedat the factory (read only).The other two are stored at the factory as standard characteristics.You can change and adapt these (three-point calibration, one-point adjustment, installationcalibration).

Note:

The data records are saved in thesensor. If you replace thetransmitter, this data is not lost. It isloaded automatically (according tothe selection) into the transmitter.

Version TB: Initial settings for residual concrete water

The version Liquisys M CUM 223-TB and CUM 253-TB contains the Plus package withadditional setting options, as for the TS version. On delivery, different values from the standardversion are set in the individual fields of the menus to make commissioning as simple aspossible.

These initial settings are so selected so that no additional settings need be made forapplications in residual concrete water. However, should you reset the device to the originalfactory settings (set default), then you can find the values which are valid for this application.

Note:

Should you wish to use a voltageoutput instead of the current outputintended by the factory, then pleaseconnected the supplied shuntresistor according to the instructionson the sheet enclosed with thetransmitter. You will then obtain a0 ... 10 V current output.

Factory settings

Note:

Calibration is carried out in the %measuring range (the transmitterswitches automatically). With theabove setting, a density of e.g. 1.12kg/l = 12 % must be selected.In individual cases, it may benecessary to adapt the calibration toa real sample. For this, a “single-point calibration” is sufficient.

With the settings in the function group SLOPE, a measured value can be adapted to areference value. All measured values are proportionally adapted over the entire measuringrange according to this change.

Example:

The displayed measured value is 2.5 g/l. It is adapted to the reference value of 2.0 g/l by meansof the slope function. The change is 20%, i.e. all measured values are reduced by 20% over theentire measuring range. An OFFSET being edited before is reset to the factory setting. Incontrast to the one-point calibration, the edited slope can be reset by setting the slope factor to1.0.

8 Diagnosis and corrective maintenance

Diagnosis

• Diagnosis refers to the identification of instrument malfunctions and defects.

Corrective maintenance:• replacement of parts diagnosed to be defective;• testing of instrument and measuring system function;• restoration of complete functionality.

Diagnosis based on the error table below and depending on difficulty and measuringequipment at hand is to be performed by:• trained operator personnel• operator’s electricians• company responsible for system installation/ operation• E+H Service.Select the required spare parts using the tables in chap. 8.2 and 8.3.

Warning:

• Disconnect the instrument from thepower source before opening itup. Work with live lines may onlybe performed by trainedelectricians.

• Switched contacts may besupplied from separate circuits.These circuits must also bede-energized before work on theterminals is performed.

Caution: ESD!

• Electronic components aresensitive to electrostaticdischarges. Personal protectivemeasures, such as discharge viaPE or permanent grounding using awrist strap, are to be taken.

• For your own safety, use onlyoriginal spare parts. Original partswill guarantee functionality,accuracy and reliability afterrepairs.

8.3.5 Special case: Replacement of controller

Note:

• After controller replacement all theeditable data are reset to thefactory settings.

• The serial number can only beentered – and only once – in thecase of a new module from thefactory with serial number 0000!Make sure that your entry iscorrect before confirming withENTER! Entry of an incorrect codewill prevent the enhancedfunctions from being enabled. Anincorrect serial number can only becorrected at the factory.

Proceed as described below after controllerreplacement:• If possible, record the user settings of the

instrument, e.g.:– Measuring range and configuration

setting– Turbidity and temperature current

assignments– relay functions selected– limits/controller settings– cleaning settings– monitoring functions– interface parameters

• Disassemble the instrument as describedin chapters 8.2.2 and 8.3.2..

• Refer to the part no. of the central moduleto determine whether the new module hasthe same part no. as the old one.

• Reassemble the instrument with the newmodule as described in chap. 8.2.3 and8.3.3.

• Start up the instrument and test its basicfunctions (e.g. meas. value andtemperature display, operation viakeyboard).

• Enter the instrument serial number:– Read the serial number (“ser-no.”) of the

instrument from the nameplate.– Enter this number in the fields E115

(year, one-digit), E116 (month, one-digit),E117 (sequence number, four-digit).

– Field E118 displays the complete numberfor verification; acknowledge with ENTERor abort and re-enter.

• Verify that the Plus package is enabled(e.g. by accessing function group CHECK/ Code P) or the Chemoclean function.

• Check the Plus package release (e.g. byopening the function group CHECK /Code P) or the Chemoclean function.

• Restore the user settings of the instrument.

8.4 Spare parts ordersSpare parts are to be ordered from your localE+H Sales Agency. See the back cover ofthese operating instructions for addresses.For this, refer to the order numbers inchapters 8.2.4 and 8.3.4.

8.6 Corrective maintenance of measuring system

8.6.1 Turbidity transmitter

The sensors CUS 31 and CUS 41 cannot besimulated as they contain the complete dataprocessing and all the measured values aretransmitted using the digital interface RS 485to CUM 223 / 253. Therefore a functionalsensor is required for the measuring point test.

Method for testing a measuring point:

• Check that device is operable and that thedisplay reacts appropriate, e.g. bypressing the PLUS key.

• Check the current outputs by carrying outa current simulation (Field O22).

• Measure the sensor operating voltage:approx. 10 ... 16 V at terminals 87 (+) and88 (–).

• The cause for a defective voltage may bepresent either at the device or at thesensor. Therefore, the next thing youshould do is

• connect a new or a different sensor.– If the function is now o.k. -> Sensor

defective.– If the sensor operating voltage is

still to low -> replace power supplymodule LSGA/LSGD (Pos. 10 / 20,check the required version).

• Sensor voltage o.k., but no measuredturbidity value even with a new sensor:-> Replace transmitter module MKT1.

Cleaning the front panel

To clean the front panel, only use standardcleaning agents.

The front panel is resistant to the followingcleaning agents (acc.• Isopropanol• Thinned acids (3 %)• Thinned alkalis (5 %)• Ester• Hydrocarbons• Ketone• Household cleaners

Caution!

Do not use any concentrated mineralacids or alkalis, benzyl-alcohol,methylene chloride or high-pressurewater vapour at over 100 °C.

8.6.2 Turbidity sensors CUS 31 / 41

The sensors CUS 31 / 41 contain their owndigital signal processor and communicatewith the turbidity measuring instrument via aninterface RS 485. All the sensor data (factorycalibration data and customer calibrationdata) are permanently saved in the sensor.

You can find detailed information on thesesensors in the “Technical InformationTurbidity sensor TurbiMax W CUS 31 / CUS31-W” TI 176C/07/en or in “TechnicalInformation Solid matter sensor TurbiMax WCUS 41 / CUS 41-W” TI 177C/07/en.

When replacing a sensor, check the following:

• Replacing the sensor CUS 31-xxA orCUS 41All the calibration data is saved in thesensor. When using the original datarecords (“read only”), no calibration isnecessary after sensor replacement.Matter-specific calibrations must berepeated.

• Replacing the sensor CUS 31-xxE orCUS 31-xxSAll the factory calibration data is saved inthe sensor. The sensor and the assemblyare calibrated together. No additionalcalibration is required for applications withpure or ultrapure water, if the sensor andthe assembly are replaced together. Thecalibration data of the sensor is transferredautomatically to the measuring instrument.
