The effective wall or bottom distance can be optimized by aligning the flat sensor side. 2 4 inch 6 8 100 FNU 10 1 0.1 0.01 B A 0 5 10 cm 15 20 a0008118 Fig. 5: A B ! 8 Effect of the distance from the wall or bottom Dark wall or bottom (non-reflective) Bright wall or bottom (reflective) Note! The following generally applies: The lower the turbidity to be measured, the darker the vessel walls should be and the greater the wall distance should also be. When measuring in drinking water, the wall distance to a dark wall must be at least 8 cm (3"). Bright pipes are not suitable for the drinking water sector. Endress+Hauser Turbimax W CUS31 Installation 3.2.3 Pipe installation The following figure illustrates various installation positions in pipes and indicates whether they are permitted or not. 3 3 2 5 4 1 2 a0008117 Fig. 6: Orientation and installation positions (with adapter CUA120-A/B resp. retractable assembly CUA451) • The pipeline diameter must be at least 100 mm (4") if reflective materials (e.g. stainless steel) are used. • Install the sensor in places with uniform flow conditions. • Orientate the sensor surface against the medium flow (self-cleaning effect). • The best installation location is in the ascending pipe (→ å 6, it. 1). Installation is also possible in the horizontal pipe (it. 5). • Do not install the sensor in places where air may collect or foam bubbles form (it. 3) or where suspended particles may settle (it. 2). • Avoid installation in the down pipe (it. 4). 3.2.4 Flow operation • Install the flow assembly as vertical as possible so that the medium flows to the sensor from below. • Two sensor orientations are possible for every installation: – Parallel to the medium flow Orientation parallel to the medium flow is required when using the CUR 3 spray head. – Against the medium flow Orientation against the medium flow is used to increase the self-cleaning effect in heavily-soiled media (> 15 FNU). The wall reflection is negligible here due to the high absorption. a0008122 Fig. 7: ! Endress+Hauser Parallel to the medium flow a0008123 Fig. 8: Against the medium flow Note! For turbidities < 5 FNU, use the sensor versions CUS31-**E or CUS31-**S. 9 Installation Turbimax W CUS31 3.2.5 Flow operation in the drinking water sector (with special calibration) When the sensor is ordered with assembly E or S, the sensor is individually calibrated in the factory with the assembly ordered. Therefore, no initial calibration on site is necessary. 1 2 P2 3 P1 P2 4 P2 > P1 P2 < P1 5 6 P2 7 P1 P2 > P1 P1 P2 8 P2 < P1 P1 a0008121 Fig. 9: Installation situations with flow assembly E resp. S 1. Correct: pressure reduction after measurement Degassing is avoided. The gas in the water remains dissolved. 2. Incorrect: Pressure reduction before measurement The pressure reduction creates favourable conditions for gas bubble formation. 3. Correct: Outlet of the assembly raised and vented Gas cannot collect in the upper section of the assembly. The outlet pipe is vented at the highest point. A slight overpressure forms in the assembly as a result of the height difference of the raised outlet. 4. Incorrect: Outlet raised but not vented A low pressure forms in the assembly if venting via the downcomer outlet pipe does not take place due to too small a cross-section. 5. Correct: Standard application in event of little initial pressure Slight overpressure due to raised outlet level, no gas collecting in the upper section of the assembly. 6. Limited application: The valve reduces the volume flow ! Note! The outlet line may not be too thin or too long as otherwise a low pressure forms in the assembly. A vent for the drain line must be present. The outlet must be completely opened at regular intervals as otherwise the raising of the outlet level would not make any sense. If using a tube as the drain line, avoid formation of siphon draw (low points in the tube)! Otherwise venting does not take place. 10 Endress+Hauser Turbimax W CUS31 Installation 7. Correct: Tube as outlet line Must be raised! 8. Incorrect: Tube not raised A low pressure forms in the assembly which favours gas bubble formation. In addition, low points in the tube result in siphon draw and thereby prevent venting. This results in pressure changes in the assembly. 3.2.6 Immersion operation When installing the sensor in immersion assemblies, please ensure that a sufficient wall distance is observed during operation. • For this reason, select an installation location in which a minimum wall distance of 150 mm (6") is observed even with varying levels or altered flow profiles. Mounting in a suspended assembly with chain must therefore be avoided. • The sensor must immerse at least 40 mm (1.5") into the medium. min. 150 (6) min. 40 (1.57) mm (inch) a0008116 Fig. 10: CYA611 with pendulum frame 3.3 Installation instructions 3.3.1 Measuring system A complete measuring system comprises: • Turbidity sensor CUS31 • Transmitter, e.g. Liquisys M CUM253 • Assembly: – Flow assembly E or S (each with installed, factory calibrated sensor) or – Immersion assembly, e.g. Dipfit W CYA611 or – Retractable assembly, e.g. Cleanfit W CUA451 Endress+Hauser 11 Installation Turbimax W CUS31 1 FNU NTU 0.127 R262 12.3 C 4 3 2 1 3 2 4 a0008114 Fig. 11: 1 2 3 4 Measuring system with flow assembly Flow assembly S CUS31-**S Sensor cable Transmitter Liquisys M CUM253 a0008115 Fig. 12: 1 2 3 4 3.3.2 Measuring system with immersion assembly Immersion assembly Dipfit W CYA611 CUS31-**A Transmitter Liquisys M CUM253 (with weather protection cover CYY101) Universal assembly holder CYH101 Notes on installation Proceed as follows for complete installation of a measuring point: " ! 1. Install the retractable or flow assembly (if used) into the process. 2. Connect the water to the rinsing nozzles (if using assembly with cleaning). 3. Install and connect the turbidity sensor. 4. Install the suspended or immersion assembly (if used) into the process. Caution! • Follow national grounding regulations when using metal assemblies and installation devices. • The sensor must be installed in an immersion assembly (e.g. CYA 611) for immersion operation. Do not use the sensor suspended freely from the cable. • Screw the sensor into the assembly in such a way that the cable does not become twisted. • Avoid large traction (e.g. by tugging) on the cable. Note! • Select a mounting location which can be easily accessed for later calibrations. • When installing without an assembly, the sensor optics must be immersed at least 4 cm (1.5") into the medium. • Please pay special attention to the installation instructions in the Operating Instructions of the assembly used. 3.4 12 Post-installation check Checks Info In general: Optical windows free of film? Permissible orientation observed? Medium present? If no: cleaning (--> "Maintenance") --> "Installation conditions" Is the assembly or piping completely filled with medium? Immersion assembly: Sensor installed in immersion assembly? Protection cap on immersion assembly? Do not use the sensor suspended freely from the cable. Prevent moisture penetrating the assembly! Flow assembly/retractable assembly: Sensor installed in flow or retractable assembly? Ensure the sensor is aligned correctly to the flow direction! Sensors with wiper --> "Maintenance" Endress+Hauser Turbimax W CUS31 Wiring 4 # Wiring Warning! • The electrical connection must only be carried out by a certified electrician. • Technical personnel must have read and understood the instructions in this manual and must adhere to them. • Ensure that there is no voltage at the power cable before beginning the connection work. 4.1 Connection to the transmitter The sensor is connected to the transmitter by means of a multi-core, shielded measuring cable (fixed cable at the sensor. To extend the measuring cable, a VBM or RM junction box and a CYK81 extension cable must be used. CUS31 GN YE WH BN CUM2x3 GND S Com A 96 Com B 97 –UB 88 +UB 87 a0008125 Fig. 13: ! Measuring cable (fixed cable) resp. extension cable (CYK81) Note! Please pay special attention to the instructions on sensor connection in the Operating Instructions of the transmitter. 4.2 Post-connection check Instrument status and specifications Remarks Are the sensor, assembly, junction box or cable damaged? Visual inspection Electrical connection Remarks Does the supply voltage of the transmitter match the specifications on the nameplate? 110/230 V AC 24 V AC/DC Are the installed cables strain-relieved and not twisted? Is the cable type route completely isolated? Power cable/signal cable Are the power supply and signal cable correctly connected to the transmitter? Use the connection diagram of CxM2x3. Are all the screws terminals properly tightened? Are all the cable entries installed, tightened and sealed? Are all the cable entries installed downwards or lateral? Endress+Hauser For lateral cable entries : cable loops downwards for water to be able to drip off. 13 Commissioning Turbimax W CUS31 5 Commissioning 5.1 Function check Before first commissioning, check if: • the sensor ist correctly installed • the electrical connection is correct. # Warning! Danger of medium leaking off Before applying compressed air to an assembly with cleaning facility, make sure the connections are correctly fitted. Otherwise, the assembly may not be insert into the process. 5.2 Calibration Each sensor is calibrated in the factory according to standard procedures (ISO 7027 / EN 27027). The wavelength of 880 nm is in the near-infrared range. The sensor zero point adjustment relates to almost particle-free water (particles < 0.2 μm). The calibration data are saved internally in the sensor as data record 1 and are also documented at the factory by means of the serial number (data cannot be modified). You can operate the sensor in the “formazine” transmitter operating mode using the factory calibration. The calibration data are automatically taken over by the transmitter once the sensor is connected to the Liquisys M CUM2x3 transmitter and power-up takes place. The measuring point is immediately operational. You can save some calibration data as data record 2 or 3 (data changeable) without losing the factory calibration in data record 1. ! Note! • Please pay special attention to the instructions on wall distance. An installation adjustment, (see Operating Instructions BA200C/07/en Liquisys M CUM2x3), may have to be performed. • For drinking water applications, versions CUS31-**E or CUS31-**S: The sensor is already installed in the assembly and is calibrated with the assembly. Recalibration at a later stage is always performed in conjunction with the assembly. 5.3 ! Setting the wiper Note! Only for versions CUS31-W**! You can set the wiping duration and the wiping intervals via the transmitter, (see Liquisys M CUM2x3 Operating Instructions). The factory setting specifies a wiping time of 30 seconds and an interval of 120 minutes. These settings are optimum for drinking water applications with little gas-bubble formation. This prevents film formation from the build-up of lime, metal oxides etc. and biological growth. The interval time must be reduced to 20 or 30 minutes for more heavily-soiled media (higher levels of lime, oxide and biological growth). The wiping time can be reduced to 20 seconds. Rapidly-forming gas bubbles which distort the measurements can occur in some applications. In such instances, set the interval time to 3 to 5 minutes and the wiping time to 5 seconds. In most cases the gas bubbles can be removed by turning the wiper once. " 14 Caution! Never move the wiper manually! Endress+Hauser Turbimax W CUS31 Maintenance 6 Maintenance You must carry out maintenance tasks at regular intervals. For this, specify the maintenance times in an operations logbook or operations calendar. The following tasks must be carried out: • Cleaning the sensor • Checking the measuring function • Checking the wiper • Recalibration You can find the description of the mentioned maintenance tasks in the following chapters. 6.1 Cleaning the sensor Contamination of the sensor can impact the measurement up to the point that measurement no longer functions, e.g. by: • Thick film build-up on the sensor optics Film build-ups can cause bad measurement results. • Wiper clogging Causes bad measurement results. The sensor must be cleaned regularly to ensure reliable measurement. The frequency and intensity of the cleaning depend on the medium. The sensor must be cleaned: • prior to every calibration • if necessary, regularly during the operation • prior to returning the sensor for repair. " ! Type of contamination Cleaning measures Lime deposits Immerse the sensor in 1-5 % hydrochloric acid (a few minutes). Dirt particles on the optics Mechanically clean the sensor head with water and a suitable brush or sponge. Fibres on the wiper axis Remove manually. Caution! After cleaning, rinse the sensor with water. Note! For automatic cleaning we recommend equipping the measuring point with a fully-automatic cleaning system, e.g. Chemoclean (Accessories). 6.2 ! Endress+Hauser Checking the measuring function 1. Remove the sensor from the medium. 2. Clean and dry the sensor. 3. Check the slope using CUY22 check unit. A stable measured value (between 2 and 6 FNU) must register. The exact value is not of importance but must be repeatable for the same sensor. Note! If measuring at air, a reliable measured value will not register (due to undefined refractive conditions). 15 Maintenance Turbimax W CUS31 6.3 ! Checking the wiper Note! Only for versions CUS31-W** Remove the sensor from the medium and carry out the following checks: Visual inspection • • • • Is the wiper still present? Is the cap on the screw still present? Is the screw or wiper arm secure? What is the condition of the wiper rubber? Replace missing or worn parts. If necessary, retighten the screw (holding the wiper arm in position). Function checks 6.4 When voltage is applied, the wiper moves to the end position (at the side of the optical windows). The check can be carried out using the ''AUTO'' key of the Liquisys M CUM2x3 transmitter. Enter Code 22, press the F key and then keep the \ key pressed until the wiper function appears on the display. The wiper can be switched on or off using the O or S keys. The wiper should not turn 360 °, but should only go from end position to end position and back. Recalibration At the factory • Remove the sensor (versions CUS31-**E/S including the assembly) and send it cleaned to your supplier or to your supplier resp. to your E+H sales centre for recalibration (order no. 50081264). • Please use the original packaging, if possible. • Enclose of a copy of the duly completed Declaration of decontamination (second-last page of these Operating Instructions) with the packaging and delivery documents. • Recalibration is carried out in the factory as per ISO 7027 / EN 27027 (traceable to formazine standard).
