With this function group you can monitor process parameters and use these for feedforward control. For this purpose, you must connect the current output of an external measured variable (e.g. flowmeter) to the 4 to 20 mA input of the transmitter. The following assignment applies: Flow in main stream Current signal in mA Current input signal in % Flowmeter start of measuring range 4 0 Flowmeter end of measuring range 20 100 Monitoring of flow in main stream This arrangement is particularly practical if the sample flow through a flow assembly in an open outlet is completely independent of the flow in the main stream. This permits signalling of an alarm condition in the main stream (flow too low or has completely stopped) and triggers dosing switch-off even if the medium flow is retained due to the method of installation. 1 A 0 B 1 Z2 Z3 0 1 C 0 E F D a0008923 Fig. 20: A B C D E Endress+Hauser Alarm signalling and dosing switch-off by the main stream Flow in main stream Relay contacts of PID controller Alarm relay Flow below switch-off limit Z4 or flow failure Flow alarm F Z2 Z3 0 1 Flow restoration Delay for controller switch-off, see field Z2 Delay for controller switch-on, see field Z3 Off On 37 Commissioning Liquisys M CUM223/253 Feedforward control to PID controller For control systems with very short reaction times, you can optimize the control.

If Z1 = off, fields Z2 to Z5 are not available. Brief flow shortfalls can be suppressed by a delay and do not result in controller switch-off. In the case of a controller, a delay until a representative measured value is received is useful if the flow fails for an extended period. 0 to 100% corresponds to 4 to 20 mA at the current input. Observe measured value assignment to the current output of the flowmeter. The controller is switched off if the value entered in Z4 is undershot or overshot. If Z6 = off, the field Z7 is not available. Z6 = basic: disturbance variable only affects the basic load (alternatively dosing in proportion to quantity can be used if usual PID controlling is not possible, due to a defective sensor, for example).

The following relay contacts can be selected and configured as desired (max. four contacts, depending on options installed): • Limit contactor for measured turbidity value: R2 (1) • Limit contactor for temperature: R2 (2) • PID controller: R2 (3) • Timer for cleaning function: R2 (4) • Chemoclean function: R2 (5) Limit contactor for measured turbidity value and temperature The transmitter has different ways of assigning a relay contact. Switch-on and switch-off points and pick-up and drop-out delays can be assigned to the limit contactor. In addition, you can configure an alarm threshold to output an error message and to start a cleaning function in conjunction with this. These functions can be used both for turbidity measurement and for temperature measurement. Please refer to Fig. 25 for a clear illustration of the relay contact states. • When the measured values increase (maximum function), the relay contact is closed as of t2 after the switch-on point (t1) has been overshot and the pick-up delay has elapsed (t2 - t1). The alarm contact switches if the alarm threshold (t3) is reached and the alarm delay (t4 - t3) has also elapsed. • When the measured values decrease, the alarm contact is reset when the alarm threshold (t5) is undershot as is the relay contact (t7) after the drop-out delay (t7 - t6). • If the pick-up and drop-out delays are set to 0 s, the switch-on and switch-off points are also switch points of the contacts. Settings can also be made for a minimum function in the same way as for a maximum function. 5 6 1 A 4 2 3 7 t1 t2 t3 t4 t5 t6 t7 t 7 B 3 2 4 6 1 5 t1 t2 t3 t4 t5 t6 t7 t C07-CxM2x3xx-05-06-00-xx-003.eps Fig. 25: A B 48 Illustration of the alarm and limit value functions Switch-on point > switch-off point: Max. function Switch-on point < switch-off point: Min. function 1 2 3 4 Alarm threshold Switch-on point Switch-off point Contact ON 5 6 7 Alarm ON Alarm OFF Contact OFF Endress+Hauser Liquisys M CUM223/253 Commissioning P(ID) controller You can define various controller functions for the transmitter. On the basis of the PID controller, P, PI, PD and PID controllers can be implemented. For an optimum control system, use the controller that best suits your application. Depending on the option selected in the R 237/R 266 field, the actuating signal can be output via relays or via current output 2 (if available). • P controller Used for simple linear control purposes with small system deviations. Where major changes are to be controlled, overshooting may occur. In addition, a lasting control deviation is to be expected. • PI controller Is used for control systems where overshooting is to be avoided and no lasting control deviation should occur. • PD controller Is used for processes that require quick changes and where peaks are to be corrected. • PID controller Is used for processes where a P, PI or PD controller does not control sufficiently. Configuration options of the PID controller The following configuration options are available for a PID controller: • Change control gain Kp (P influence) • Set integral action time Tn (I influence) • Set derivative action time Tv (D influence) Basic load dosing (Basic) The basic load dosing (field R231) is used to set a constant dosage (field R2311) PID controlling plus basic load dosing If you select this function (PID + Basic) in field R231 the PID controlled dosage will not be lower than the basic load value entered in field R2311.

Proceed as follows to optimize the control circuit further: • Increase the control gain Kp until the controlled variable just starts to overshoot. • Reduce Kp slightly and then reduce the integral action time Tn so that the shortest possible correction time without overshooting is achieved. • To reduce the response time of the controller, also set the derivative action time Tv.

A distinction is made according to the type of signal cycle: • Pulse length modulation The bigger the calculated manipulated variable is, the longer the contact affected remains picked up. The period T can be adjusted between 0.5 and 99 s (field R238). Outputs with pulse length modulation are used to activate solenoid valves. • Pulse frequency modulation The bigger the calculated manipulated variable is, the higher the switching frequency of the contact affected. The maximum switching frequency 1/T can be set between 60 and 180 min-1. The on-time tON is constant. It depends on the set maximum frequency and is approx. 0.5 s for 60 min-1 and approx. 170 ms for 180 min-1. Outputs with pulse frequency modulation are used to activate directly controlled solenoid dosing pumps.

However, Chemoclean also gives you the added option of defining different cleaning and rinsing intervals. As a result, it is possible to clean irregularly with different repeat cycles and to separately set the cleaning times with post rinse times. Pay attention to the following: • To use the Chemoclean function the transmitter has to be equipped with a designated relay board (see product structure or chapter "accessories"). • Timer and Chemoclean do not work independently of one another. While one of the two functions is active, the other cannot be started. • For the Chemoclean function, the relays 3 (water) and 4 (cleaner) are used. • If cleaning is prematurely aborted, a post rinse time always follows. • If the setting is "Economy", cleaning only takes place with water. 1 A 0 1 B 0 1 C 0 t0 t1 t2 t4 t3 t5 a0006793 Fig. 30: A B C 0 1 Endress+Hauser Sequence of a cleaning cycle Hold Water Cleaner Contact on Contact off t0 t1 t2 - t1 t3 - t2 t4 - t3 t5 - t4 Normal mode Cleaning start Pre-rinse time Cleaning time Post rinse time Hold dwell period 53 Commissioning Liquisys M CUM223/253 Basic version does not include functions in italic.

The calibration data are saved in an EEPROM directly in the sensor. For this reason: • Recalibration is not required in the event of a power failure • Recalibration is not required when the transmitter is replaced • Customer-specific recalibration is required, however, when the sensor is replaced Three calibration data records are saved in the sensor for each of the four main operating modes. FNU/NTU ppm or mg/l g/l % Factory data record no. 1 not changeable Formazine SiO2 Activated sludge Residual concrete water User data record no. 2 changeable Formazine Kaolin Activated sludge Residual concrete water User data record no. 3 changeable Formazine SiO2 Activated sludge Residual concrete water Select the desired data record in the SETUP 2 function group in the B4 field. • In the FNU operating mode, the sensor is factory calibrated with formazine traceable to ISO 7027. • In the ppm operating mode, the calibration data records for Kaolin and SiO2 are derived from the FNU data records. • In the % operating mode, the calibration data records are set to the average of various residual concrete waters. They are preset in such a way that correct values are displayed for average clarity. However the settings do not follow a standard currently applicable. • In the g/l operating mode also, the sensor is not calibrated to a fixed value as no standard is directly applicable. You must carry out a calibration because the media of the various applications differ too greatly here. Three-point sensor calibration is the standard calibration. It is absolutely essential: • When commissioning the sensor in sludge applications • When changing to another sludge type Three-point sensor calibration is not necessary: • When commissioning the sensor in the drinking water area (sensor has been calibrated for drinking water applications in the factory). • For residual concrete water. Density measurement for determining the concentration of residual concrete water is based on %–data records. They are preset in such a way that correct values are displayed for average clarity. One-point calibration is often sufficient to adjust the system in the event of deviating values. • When recalibrating with the same sludge type. One-point calibration suffices here if the degrees of lightness and clarity, for example, do not differ too greatly. 64 Endress+Hauser Liquisys M CUM223/253 Commissioning Pay attention to the following: • Sludge samples tend sediment. Mix the sample well, even during the calibration process, but not to the extent that gas bubbles are formed. • The sensor has to be far enough away from the floor and the wall of the calibration vessel during calibration. The immersion depth must be at least 40 mm. • The characteristic determined during the calibration is stored in the selected data record (Setup 2, B4 field). • Calibration is not possible if data record 1 is selected with the factory setting. • If the calibration data deviate from the standard values by a factor of two or more, a warning (E084) is output. The calibration results are accepted. • If the calibration results are outside the permitted range, a calibration error (E045) is indicated. The calibration results are not accepted. • For every type of calibration, the installation adjustment and the offset are reset to zero and the slope to 1.0. Calibration menu The calibration menu offers the following options: 3–Pt Three-point calibration Corr Three-point correction Edit Edit calibration Refl Installation adjustment 1–Pt One-point calibration Data Calibration data Three-point calibration (3–Pt) You should perform the calibration in the turbidity/solids concentration range in which you plan to measure. The overall calibration characteristic of the measuring chain is determined using three samples of known turbidity or known solids content. Calibration with a very dark, high-absorption medium returns small slopes while light, clear media return big slopes. You can create the requisite probes by diluting a medium sample. In general, very good calibration results are achieved with a concentration gradation of 10 %, 33 % and 100 %. The following condition must be met for the calibration: Sample A > 1.1 x sample B > 1.1 x sample C a0006961 Fig. 31: A B C Endress+Hauser Making the samples for a three-point calibration Original sample 1 part sample A + 2 parts water 1 part sample A + 9 parts water 65 Commissioning Liquisys M CUM223/253 A different dilution ratio should be selected for very high-absorption media to achieve accurate calibration results. Instead of 100 % – 33 % – 10 %, you can use dilution ratios of 100 % – 20 % – 5 % or 100% – 10 % – 3.3 %. If the scattered light of a light sample hits a sensor that is calibrated for a dark medium, it can happen that the signal value is so high that it is above the calibration curve. Three-point correction (Corr) If the calibration was performed with an unknown sample concentration but with a defined dilution, the correct value determined afterwards in the laboratory is entered here. Edit calibration (Edit) If each of the samples has been determined afterwards in the laboratory, the correction for the calibration is entered here. Installation adjustment (Refl) In installation adjustment, backscatter from the immediate sensor environment is compensated. Installation adjustment must be performed with a medium whose turbidity is lower than 2 FNU or 5 ppm. One-point calibration (1–Pt) In the area of TS/concentration measurement, one-point calibration is used to change the conversion factor (field C166). The slopes are not changed. In the FNU range, the two slope values are adjusted by a one-point calibration. This is possible because the conversion factor in the FNU range is always 1 and the editing range is limited to 4000 FNU. In this way, the two curves are always increasing and the calibration remains clear. In the ppm range, the slope values are adjusted up to 500 ppm. For higher values, the conversion factor is changed. Calibration data (Data) Here, you can display the calibration points 1 to 3, slope 1 and 2 and the conversion factor. With three-point calibration, the curves used in the algorithm are adjusted as precisely as possible using the data points acquired. The difference between the ideal curve of the algorithm and the three actual calibration points can be found as a correction factor in the C161, C162 and C163 fields of the data function. The correction values are indicated in %. The values should be as close to 100 % as possible. Values from 70 to 80 % are acceptable. 50 % in one or two calibration points clearly indicates a problematic calibration. A warning (E084) is output here for this reason. This can mean that significant deviations can occur between the calibration points. The calibration points themselves are always retrieved correctly. 66 Endress+Hauser Liquisys M CUM223/253 Commissioning Version TB: Initial settings for residual concrete water The version TB contains the Plus-package with additional setting options. The default values set in individual fields of the menus differ from the standard version to make commissioning as simple as possible. These values are so selected that no additional settings need to be made for applications in residual concrete water.

Maintenance work at the transmitter comprises: • Calibration (see "Calibration" section) • Cleaning of assembly and sensor • Cable and connection check When performing any work on the device, bear in mind any potential impact this may have on the process control system or on the process itself. NOTICE Electrostatic discharge (ESD) Risk of damage to 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, use only genuine spare parts. With genuine spare parts, the function, accuracy and reliability are also guaranteed after repair. 8.1 Maintenance of the entire measuring point 8.1.1 Cleaning the transmitter Clean the front of the housing with usual commercial cleaning agents. In accordance with DIN 42 115, the front is resistant to: • Ethanol (short periods) • Diluted acids (max. 2% HCl) • Diluted bases (max. 3% NaOH) • Soap-based household cleaners NOTICE Prohibited cleaning agents Damage to the housing surface or housing seal ‣ For cleaning purposes, never use concentrated mineral acids or bases. ‣ Never use organic cleaners such as benzyl alcohol, methanol, methylene chloride, xylene or concentrated glycerol cleaner. ‣ Never use high-pressure steam for cleaning purposes. Endress+Hauser 83 Maintenance Liquisys M CUM223/253 8.1.2 Checking the measuring point The sensors CUS31 and CUS41 cannot be simulated as they contain the complete data processing and all the measured values are transmitted to CUM223/253 using the digital interface RS 485. Therefore a functional sensor is required for the measuring point test. Method for testing a measuring point: • Check that device is operable and that the display reacts appropriately, e.g. by pressing the PLUS key. • Check the current outputs by carrying out a current simulation (Field O3(2)). • Measure the sensor operating voltage: approx. 10 to 16 V at terminals 87 (+) and 88 (–). • The cause for an incorrect voltage may be present either at the device or at the sensor. – Replace the sensor. – If the sensor operating voltage is still too low replace the power supply module LSGA/ LSGD (Pos. 10/20, make sure to use the appropriate version - see spare parts). • Sensor operating voltage is o.k. but no measured turbidity value even with a new sensor. Replace the transmitter module MKT1. 8.1.3 Replacing the sensor The sensors CUS31/CUS41 contain their own digital signal processor and communicate with the turbidity measuring instrument via an interface RS 485. All sensor data (factory calibration data and customer calibration data) are permanently saved in the sensor. You can find detailed information on these sensors in the: • Operating Instructions Turbimax W CUS31 BA00176C/07/EN. • Technical Information Turbimax W CUS41 TI00177C/07/EN. When replacing a sensor pay attention to the following: • Replacing the sensor CUS31-xxA or CUS41 All calibration data are saved in the sensor. When using the original data records (“read only”), no calibration is necessary after sensor replacement. Medium-specific calibrations must be repeated. • Replacing the sensor CUS31-xxE or CUS31-xxS All factory calibration data are saved in the sensor. The sensor and the assembly are calibrated together. No additional calibration is required for applications with pure or ultrapure water, if the sensor and the assembly are replaced together. The calibration data of the sensor are automatically transferred to the measuring instrument. 8.1.4 Maintenance assembly Please refer to the corresponding assembly Operating Instructions for information on maintaining and trouble-shooting the assembly. Here you can find a description for assembling and disassembling, sensor replacement, seal replacement, as well as information on stability and spare parts and accessories. 84 Endress+Hauser Liquisys M CUM223/253 Repair 9 Repair Spare parts are to be ordered from your sales center responsible.
