Repairs not described in the Operating Instructions provided may only be carried out directly by the manufacturer or by the service organization. 2.2 Designated use The sensor measures conductivity in water or steam circuits, such as in the power plant and energy industry: • Condensate monitoring • Boiler feedwater monitoring • Boiler blowdown monitoring The sensor can be used in all applications with a low conductivity and high, CLS13 with very high, temperatures and pressures. Sensor versions with explosion protection approval according to ATEX, FM or CSA are suitable for use in hazardous areas. Use of the device for any purpose other than that described, poses a threat to the safety of people and of the entire measuring system and is therefore not permitted. The manufacturer is not liable for damage caused by improper or non-designated use. 2.3 Occupational safety As the user, you are responsible for complying with the following safety conditions: • Installation guidelines • Local standards and regulations • Regulations for explosion protection Electromagnetic compatibility • The product has been tested for electromagnetic compatibility in accordance with the applicable European standards for industrial applications. • The electromagnetic compatibility indicated applies only to a product that has been connected in accordance with these Operating Instructions. 2.4 1. 4 Operational safety Before commissioning the entire measuring point, verify that all connections are correct. Ensure that electrical cables and hose connections are undamaged. Endress+Hauser Condumax CLS12/CLS13 Basic safety instructions 2. Do not operate damaged products, and safeguard them to ensure that they are not operated inadvertently. Label the damaged product as defective. 3. If faults cannot be rectified: Take the products out of operation and safeguard them to ensure that they are not operated inadvertently. 2.5 Product safety 2.5.1 State of the art The product is designed to meet state-of-the-art safety requirements, has been tested, and left the factory in a condition in which it is safe to operate. The relevant regulations and European standards have been observed. 2.5.2 Electrical equipment in hazardous areas • The sensors CLS12 / CLS13 have been developed and manufactured in compliance with applicable European standards and guidelines and are suitable for use in hazardous areas. The EC type examination certificate confirms compliance with the harmonized European standards for using the sensors in hazardous areas. The corresponding EU declaration of conformity is part of this document. • The sensors may only be operated on suitable intrinsically safe circuits. Make sure that the maximal permissible sensor input characteristic values, the maximum permissible inductance Li and capacitance values Ci in these circuits and the ambient temperature ranges indicated are not exceeded. • The electrical connection must be made according to the wiring diagram of the transmitter. • Metallic process connection parts must be mounted at the mounting location electrostatically conductive (< 1 MΩ). • The maximum permissible cable length is limited by the maximum permissible characteristic values of the transmitter: the total of the maximum permissible inductance Li and capacitance values Ci for the sensor and measuring cable may not exceed the maximum permissible inductance Lo and capacitance values Co for the transmitter. • The sensors CLS12 and CLS13 must be installed in such a way that they are protected against friction and impact. • Full compliance with regulations for electrical systems in hazardous areas (e.g. EN/IEC 60079-14) is mandatory when using the devices and sensors.

Alternatively you can install the sensor in a flow assembly CLA751. Ensure that the electrodes are fully immersed in the medium during measurement. If the sensor is being used in the ultrapure water range, you must work under air-evacuated conditions. Otherwise the CO2 in the air can dissolve in the water and its (weak) dissociation can increase the conductivity by up to 3 µS/cm. 4.2 Post-installation check • Are the sensor and cable undamaged? • Is the sensor installed in the process connection and is not suspended from the cable? 5 Electrical connection LWARNING Device is live Incorrect connection may result in injury or death ‣ The electrical connection may be performed only by an electrical technician. ‣ The electrical technician must have read and understood these Operating Instructions and must follow the instructions contained therein. ‣ Prior to commencing connection work, ensure that no voltage is present on any cable.

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 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? Endress+Hauser 11 Commissioning 6 Condumax CLS12/CLS13 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. 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. 12 Endress+Hauser Condumax CLS12/CLS13 Repair 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 . 8 Repair 8.1 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.
