With this function group, you can monitor process parameters and use them for feedforward control. For this purpose, you must connect the current output of an external measured variable (e.g. flowmeter) to the 4 to 20mA 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 Flow monitoring in the main stream This arrangement is particularly practical if the sample flow through a flow assembly in an open outlet is independent of the flow in the main stream. This permits signaling 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 maintained due to the method of installation. 1 A 0 1 B Z2 Z3 0 1 C 0 E F D A0008923  25 Alarm signaling and dosing switch-off by the main stream A Flow in main stream F Flow restoration B Relay contacts of PID controller Z2 Delay for controller switch-off, see field Z2 C Alarm relay Z3 Delay for controller switch-on, see field Z3 D Flow below switch-off limit Z 4 or flow failure 0 Off E Flow alarm 1 On Feedforward control to PID controller You can optimize control on control systems with very short response times by measuring the medium flow rate in addition to the oxygen content.

An alarm (E152) is triggered if the measuring signal remains constant within the space of one hour. The reason for such sensor behavior can be contamination, cable open circuit or similar. CC (controller check): You can monitor the controller activity with the CC function . This function is primarily suited to batch operation and single-sided limit switches.

This function is primarily suited to batch operation and single-sided limit switches. A0009055-EN 7.4.7 Relay configuration For the "RELAY" function group, you require a relay card which is not available in the basic device version. The following relay contacts can be selected and configured as desired (max. four contacts, depending on options installed): • Limit contactor for conductivity measured value: R2 (1) • Limit contactor for temperature: R2 (2) • PID controller: R2 (3) • Timer for cleaning function: R2 (4) • Chemoclean function: R2 (5) • USP/EP: R2 (6) and R2 (7) (for Plus Package, only conductive sensors) Limit contactor for conductivity measured value and temperature The transmitter has different ways of assigning a relay contact. Switch-on and switch-off points and pickup and dropout 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 the primary value and for temperature measurement. Please refer to the switch states in →  29 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 exceeded and the pickup 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 (errors E067 to E070). • When the measured values decrease, the alarm contact is reset when the value falls below the alarm threshold (t5) again, as is the relay contact (t7) after the dropout delay (t7-t6). • If the pickup and dropout delays are set to 0 s, the switch-on and switch-off points are also switch points of the contacts. The same settings can also be made for a minimum function in the same way as for the maximum function.

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. • 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 must 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 must be corrected. • PID controller Is used for processes where a P, PI or PD controller does not control sufficiently. Configuration options of the P(ID) 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) You can set a constant dosage amount (field R2311) with basic load dosing (field R231).

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 again 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 set to be 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 to be between 60 and 180 min-1 (field R239). 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. 170 ms. Outputs with pulse frequency modulation are used to activate directly controlled solenoid dosing pumps. 56 Endress+Hauser Liquisys M CLM223/253 Commissioning A t1 A t2 t1 1 1 0 0 t [s] T T1 T2 t [s] A0025219  32 Signal of a pulse-length modulated controller contact (left) and of a pulse frequency-modulated controller contact (right) Contact: 1 = on, 0 = off T Period Time (s): t1 = ton t2 = toff T1 T2 Impulse period length ( 1/T1 and 1/T2) Constant controller The controller can also control the second analog current output (if provided).

Other cleaning functions are available for selection in conjunction with the Chemoclean function (device version with four contacts required, see the "Chemoclean function" section).

However, Chemoclean also gives you the added option of defining various cleaning and rinsing intervals and of dosing cleaning agent. Therefore, it is possible to clean irregularly with different repeat cycles and to separately set the cleaning times with post rinse times. Please note the following: • To use the Chemoclean function the transmitter has to be equipped with a designated relay board (see product structure or chapter "accessories"). • The timer and Chemoclean are mutually dependent. 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 the cleaning is prematurely aborted, a post rinse time always follows. • If the setting is "Economy", cleaning only takes place with water. 58 Endress+Hauser Liquisys M CLM223/253 Commissioning 1 A 0 1 B 0 1 C 0 t0 t1 t2 t4 t3 t5 A0025216  35 Sequence of a cleaning cycle A Hold function B Water valve is triggered C Cleaning valve is triggered 0 Contact off 1 Contact on t0 Normal operation t1 cleaning start t2-t1Pre-rinse time t3-t2Cleaning time t4-t3Post rinse time t5-t4Hold dwell period Limit values for pharmaceutical water according to United States Pharmacopoeia (USP) and European Pharmacopoeia (EP) (only for conductive sensors) In the case of conductive sensors, the transmitter has functions for monitoring "Water for Injection" (WFI), "Highly Purified Water" (HPW) and "Purified Water" (PW) according to the United States Pharmacopoeia (USP) Part 645 and European Pharmacopoeia (EP) standards.

The transmitter can convert from conductivity values to concentration values. For this purpose, the operating mode is first set to concentration measurement (see field A1). Afterwards, in the measuring device you must specify the basic data on the basis of which the concentration is to be calculated. You require the conductivity characteristic curves of the medium for this. In the case of conductive sensors, the effects of polarization in the boundary layer between the sensor and medium restrict the measuring range. The transmitter can detect polarization effects by using a smart signal analysis process. Error message E071 is displayed. You can either refer to your data sheets for these characteristic curves or determine the characteristic curves yourself. 1. Create samples of the medium in the concentrations that occur in the process. 2. Then measure the uncompensated conductivity of these samples at temperatures that also occur in the process. • For variable process temperatures: If variable process temperatures are to be taken into consideration, you must measure the conductivity for at least two temperatures (ideally the minimum and maximum process temperature) for the samples created. The temperature values of the various samples must be identical in each case. The temperatures must be at least 0.5 °C apart. At least two samples of different concentrations, taken at two different temperatures in each case, are required as the transmitter needs at least four points in the table (this must include the minimum and maximum concentration values). • For constant process temperatures: Measure the differently concentrated samples at this temperature. At least two samples are required. At the end you should have measuring data which resemble those shown in the following figures. 2 k k T3 1 2 T3 1 T2 T2 T1 Cmin Cmax T1 C Cmin Cmax C A0008926  36 κ C T 1 2 70 Example of measured data for variable temperatures Conductivity Concentration Temperature Measuring point Measuring range Endress+Hauser Liquisys M CLM223/253 Commissioning k k 1 1 T Cmin Cmax C Cmin T C Cmax A0008925  37 κ C T 1 Example of measured data for constant temperatures Conductivity Concentration Constant temperature Measuring range The characteristic curves received from the measuring  points must increase or decrease very monotonically in k k the range of the process conditions, i.e. neither maximum points, nor minimum points, nor ranges with a constant behavior can occur.

Please note the following: If the measured values of the process are outside the range of your sample values, this considerably reduces the level of accuracy and the error message E078 or E079 will be displayed. Therefore, take the limit values of your process into consideration when determining the characteristic curves. Wird bei aufsteigender If you enter an additional value triplet of 0 μS/cm and 0% for every temperature used when the characteristic curve is increasing, you can work from the start of the measuring range with sufficient accuracy and without an error message.

Use this function group to calibrate and adjust the transmitter. The calibration can be performed in two different ways: • By measuring in a calibration solution of known conductivity. • By entering the exact cell constant of the conductivity sensor. Please note the following: • During initial commissioning of inductive sensors, an air set is absolutely essential for residual coupling compensation (from field C111) so that the measuring system can return precise measurement data. • If the calibration procedure is aborted by pressing the PLUS and MINUS keys at the same time (return to C114, C126 or C136) or if the calibration is faulty, then the previous calibration data are reinstated. A calibration error is indicated by “ERR” and the sensor symbol flashes on the display. Repeat calibration! • For each calibration, the device automatically switches to hold (factory setting). • On completion of the calibration, the device returns to the measurement mode. The "hold" symbol appears on the display during the hold dwell period (field S4). • Only items C121 to C126 are relevant for conductive sensors.

Otherwise the following applies: Conductivity [mS/cm] = k[cm-1] ⋅ 1 / R[kΩ] Resistance R 10 Ω Cell constant k 1 100 mS/cm cm-1 1000 mS/cm 10 100 Ω 1000 Ω 10 kΩ 1 mS/cm 1 cm-1 10 mS/cm 10 cm-1 100 mS/cm 0.1 cm-1 0.1 mS/cm 1 cm-1 1 mS/cm 10 cm-1 10 mS/cm 0.01 cm-1 1 μS/cm 1 MΩ ⋅ cm 0.1 cm-1 10 μS/cm 100 kΩ ⋅ cm cm-1 100 μS/cm cm-1 1 mS/cm 10 1 0.1 μS/cm 10 MΩ ⋅ cm 1 μS/cm 1 MΩ ⋅ cm 10 MΩ 0.01 μS/cm 100 MΩ ⋅ cm cm-1 0.1 μS/cm 10 MΩ ⋅ cm cm-1 1 μS/cm cm-1 0.001 μS/cm cm-1 0.01 μS/cm 0.01 0.1 10 μS/cm cm-1 0.01 1 10 kΩ ⋅ cm cm-1 cm-1 0.1 1 kΩ ⋅ cm cm-1 0.01 0.1 1 MΩ Display for MΩ 0.1 cm-1 1 100 kΩ Display for conductivity cm-1 100 MΩ ⋅ cm The MΩ measurement is normally used for pure and ultrapure water and therefore only makes sense for cell constants k= 0.01 cm-1 or k = 0.1 cm-1. 9.1.4 Simulation of inductive sensors for device testing The inductive sensor cannot be simulated. However, the overall system comprising the transmitter and inductive sensor can be tested using equivalent resistors. Note the cell constant k (e.g. knominal = 1.98 cm-1 for CLS50, knominal = 5.9 cm-1 for CLS52, knominal = 6.3 cm-1 for CLS54). For accurate simulation, the actual cell constant used (visible in field C124) must be used to calculate the display value. The formula for calculation also depends on the type of sensor: • CLS50 and CLS52: conductivity reading [mS/cm] = k[cm-1] ⋅1/R[kΩ] • CLS54: conductivity reading [mS/cm] = k[cm-1] ⋅1/R[kΩ] ⋅ 1.21 92 Endress+Hauser Liquisys M CLM223/253 Maintenance Values for simulation with CLS50 at 25 °C (77 °F): Simulation resistance R Default cell constant k Conductivity reading 1.98 cm-1 990 mS/cm 1.98 cm-1 198 mS/cm 1.98 cm-1 19.8 mS/cm 1.98 cm-1 1.98 mS/cm Simulation resistance R Default cell constant k Conductivity reading 10 Ω 6.3 cm-1 520 mS/cm 26 Ω 6.3 cm-1 200 mS/cm 100 Ω 6.3 cm-1 52 mS/cm 260 Ω 6.3 cm-1 20 mS/cm 2.6 kΩ 6.3 cm-1 2 mS/cm 26 kΩ 6.3 cm-1 200 μS/cm 52 kΩ cm-1 100 μS/cm 2Ω 10 Ω 100 Ω 1 kΩ Simulation with CLS54 at 25 °C (77 °F): 6.3 Conductivity simulation: Pull a cable through the sensor opening and then connect it to a decade resistor, for instance. 9.1.5 Checking conductive sensors • Measuring surface connection: The measuring surfaces are directly connected to the connections of the sensor connector. Check with ohmmeter for < 1 Ω. • Measuring surface shunt: A shunt is not permitted between the measuring surfaces. Check with ohmmeter for > 20 MΩ. • Temperature sensor shunt: A shunt is not permitted between the measuring surfaces and the temperature sensor. Check with ohmmeter for > 20 MΩ. • Temperature sensor: See the sensor nameplate for information on the type of the temperature sensor being used. The sensor can be checked at the sensor connector with an ohmmeter: – Pt 100 at 25 °C (77 °F) = 109.79 Ω – Pt 1000 at 25 °C (77 °F) = 1097.9 Ω – NTC 30 k at 25 °C (77 °F) = 30 kΩ • Terminal: For sensors with a terminal connection (CLS12/13) check the assignment of the terminals to ensure they have not been inadvertently interchanged. Check the tightness of the terminal screws. Endress+Hauser 93 Maintenance Liquisys M CLM223/253 9.1.6 Checking inductive sensors The following applies to the CLS50, CLS52 and CLS54 sensors. The sensor cables must be disconnected at the device or junction box for all tests described here! • Testing the transmitting and receiving coils: Perform the measurement at the white and red coaxial cables, between the inner conductor and shield in each case. – Ohmic resistance CLS50/52: approx. 0.5 to 2 Ω CLS54: approx. 1 to 3 Ω – Inductance approx. 180 to 500 mH (for 2 kHz, series circuit as equivalent circuit diagram) CLS50: approx. 250 to 450 mH CLS52/54: approx. 180 to 550 mH • Testing the coil shunt: A shunt is not permitted between the two sensor coils (from red coax to white coax). The measured resistance must be > 20 MΩ. Test with the ohmmeter from the red coax cable to the white coax cable. • Temperature sensor test: Use the table in the "Simulation of conductive sensors for device testing" section to check the Pt 100 / Pt 1000 in the sensor. Measure between the green and white wires and between the green and yellow wires. The resistance values must be identical. • Temperature sensor shunt test: Shunts are not permitted between the temperature sensor and the coils. Check with ohmmeter for > 20 MΩ Measure between the temperature sensor wires (green + white + yellow) and the coils (red and white coax). 9.1.7 Assembly Refer to the assembly operating manual for information on servicing and troubleshooting the assembly. The assembly operating manual describes the procedure for mounting and disassembling the assembly, replacing the sensors and seals, and contains information on the material resistance properties, as well as on spare parts and accessories. 9.1.8 Connecting cables and junction boxes • Use the methods described in chapters "Simulation of conductive/inductive sensors for device test" to perform a quick functional check from the conductivity sensor (sensor connector) to the measuring instrument via an extension. The easiest way to connect resistor decades is with the "Conductivity testing adapter" service kit, order number: 51500629 • Check junction boxes for: – Moisture (influence at low conductivity or for MΩ measurement, where necessary dry box, replace seals, insert dehydrating bag) – Correct connection of all lines – Connection of the outer shields – Tightness of the terminal screws 94 Endress+Hauser Liquisys M CLM223/253 Repair 10 Repair 10.1 Spare parts Please order spare parts from your local Sales Office.
