Sheetmetal brackets have a lower dimensional stability, uneven bearing surfaces causing point loads, and sometimes sharp edges that can damage the clamp. We recommend you only use solid brackets due to their higher dimensional stability. Solid brackets can be used over the entire pressure/temperature range (see pressure-temperature ratings). 14 Endress+Hauser Condumax CLS15D/16D/21D Installation The sensors are installed directly via the process connection.

Always connect the sensor gently. ‣ If the Memosens coupling clearly will not close, check the coupling for dirt or mechanical damage and make sure you are turning in the right direction. Pay attention to the lock symbol on the coupling. ‣ Use another Memosens cable if necessary. 5.3 Ensuring the degree of protection Only the mechanical and electrical connections which are described in these instructions and which are necessary for the required, designated use, may be carried out on the device delivered. ‣ Exercise care when carrying out the work. Otherwise, the individual types of protection (Ingress Protection (IP), electrical safety, EMC interference immunity) agreed for this product can no longer be guaranteed due, for example, to covers being left off or cable (ends) which are loose or insufficiently secured. 5.4 Post-connection check Device condition and specifications Notes Are the outside of the sensor, assembly, cable undamaged? Visual inspection Electrical connection Notes Are the installed cables strain-relieved and not twisted? Is a sufficient length of the cable cores stripped, and is it positioned in the terminal correctly? Check the fit (by pulling gently) Are all the screws terminals properly tightened? Tighten Endress+Hauser 19 Commissioning Condumax CLS15D/16D/21D Device condition and specifications Notes Are all cable entries mounted, tightened and leak-tight? For lateral cable entries, make sure the cables loop downwards to allow water to drip off Are all cable entries installed downwards or mounted laterally? 6 Commissioning Before first commissioning, check if: • the sensor is correctly installed • the electrical connection is correct. If using an assembly with automatic cleaning, check that the cleaning medium (e.g. water or air) is connected correctly. LWARNING Escaping process medium Risk of injury from high pressure, high temperatures or chemical hazards ‣ Before applying compressed air to an assembly with cleaning facility, make sure the connections are correctly fitted. ‣ Do not install the assembly in the process if you cannot make the correct connection reliably. 7 Maintenance LCAUTION Corrosive chemicals Danger of chemical burns to the eyes and skin. Danger of damage to clothing and equipment ‣ It is absolutely essential to protect the eyes and hands properly when working with acids, bases and organic solvents! ‣ Wear protective goggles and safety gloves. ‣ Clean away splashes on clothes and other objects to prevent any damage. ‣ Pay particular attention to the information provided in the safety data sheets for the chemicals used. LWARNING Hydrofluoric acid and mineral acids Risk of serious or fatal injury from caustic burns ‣ Wear protective goggles to protect your eyes. ‣ Wear protective gloves and appropriate protective clothing. ‣ Avoid all contact with the eyes, mouth and skin. ‣ If using hydrofluoric acid, only use plastic vessels. 20 Endress+Hauser Condumax CLS15D/16D/21D Repair LWARNING Thiocarbamide Harmful if swallowed. Limited evidence of carcinogenicity. Possible risk of harm to the unborn child. Dangerous for the environment with long-term effects. ‣ Wear protective goggles, protective gloves and appropriate protective clothing. ‣ Avoid all contact with the eyes, mouth and skin. ‣ Avoid releases into the environment. Clean away fouling on the sensor as follows depending on the type of fouling: 1. Oily and greasy films: Clean with grease remover, e.g. alcohol, as well as hot water and (alkaline) agents containing surfactants (e.g. dishwashing detergent). 2. Lime, cyanide and metal hydroxide buildup and low solubility organic buildup: Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with plenty of clear water. 3. Sulfidic buildup (from flue gas desulfurization or sewage treatment plants): Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available) and then rinse thoroughly with plenty of clear water. 4. Buildup containing proteins (e.g. food industry): Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then rinse thoroughly with plenty of clear water. 5. Readily soluble biological buildup: Rinse with pressurized water. After cleaning or regeneration, you must rinse the sensor thoroughly with water and then recalibrate it. 8 Repair 8.1 Sealing ring replacement and recalibration (CLS16D only) Intact seals are a prerequisite for safe and reliable measurements. The seal should be replaced at regular intervals to guarantee maximum sensor operational safety and hygiene. Practical repair intervals can only be determined by the user as they depend greatly on the operating conditions, such as: • Type and temperature of the product • Type and temperature of the cleaning agent • Number of cleanings • Number of sterilizations • Operating environment Endress+Hauser 21 Repair Condumax CLS15D/16D/21D Recommended intervals for seal replacement (reference values) Application Window Media with temperatures from 50 to 100 °C (122 to 212 °F) Approx. 18 months Media with temperatures < 50 °C (122 °F) Approx. 36 months Sterilization cycles, max. 150 °C (302 °F), 45 min. Approx. 400 cycles To ensure your sensor is operational again after being exposed to very high loads, you can have it regenerated in the factory. In the factory, the sensor is fitted with new seals and recalibrated. Please contact your sales office for information on replacing the seal and recalibration in the factory. 8.2 Return The product must be returned if repairs or a factory calibration are required, or if the wrong product was ordered or delivered. As an ISO-certified company and also due to legal regulations, Endress+Hauser is obliged to follow certain procedures when handling any returned products that have been in contact with medium. To ensure swift, safe and professional device returns, please read the return procedures and conditions at www.endress.com/support/return-material. 8.3 Disposal The device contains electronic components and must therefore be disposed of in accordance with regulations on the disposal of electronic waste. Observe the local regulations. 22 Endress+Hauser Condumax CLS15D/16D/21D 9 Technical data 9.1 Input 9.1.1 Measured values Technical data • Conductivity • Temperature 9.1.2 Measuring ranges Conductivity CLS15D-A CLS15D-B/L CLS16D CLS21D Temperature CLS15D CLS16D CLS21D 9.1.3 -20 to 100 °C (-4 to 212 °F) -5 to 100 °C (23 to 212 °F) -20 to 100 °C (-4 to 212 °F) Cell constant CLS15D-A CLS15D-B/L CLS16D CLS21D 9.1.4 (in relation to water at 25 °C (77 °F)) 0.04 to 20 μS/cm 0.10 to 200 μS/cm 0.04 to 500 μS/cm 10 μS/cm to 20 mS/cm k = 0.01 cm–1 k = 0.1 cm–1 k = 0.1 cm–1 k = 1.0 cm–1, nominal Temperature compensation NTC 30K Endress+Hauser 23 Technical data Condumax CLS15D/16D/21D 9.2 Performance characteristics 9.2.1 Uncertainty of measurement CLS15D Each individual sensor is factory-measured in a solution of approx. 5 μS/cm for cell constant 0.01 cm-1 or approx. 50 μS/cm for cell constant 0.1 cm-1 using a reference measuring system traceable to NIST or PTB.
