The following also applies for all the sensors listed • Compliance with the specified ambient and medium temperature ranges is a prerequisite for safe use. • The sensor must be connected and operated in accordance with the Operating Instructions of the sensor and of the transmitter to be connected. All sensor operating data must be observed. • Avoid electrostatic charge. Metal process connections must be electrostatically connected (R ≤ 1 MΩ). • Non-metal process connections must be protected against electrostatic charge. • In order to avoid electrostatic charge clean the sensor with a damp cloth only. • Full compliance with regulations for electrical systems in hazardous locations (EN60079-14) is mandatory when using the devices and sensors. • Ensure correct installation to maintain the housing protection type. (Use original seal. Fit cable entry properly. Tighten nut). • The degree of protection only applies when the flange is mounted. CLS50 only In the CLS50 sensor, the internal sensor circuits are connected with the shielded wire of the supply cable. When installing the CM42 or CLM153 transmitter, the shielding of the sensor cable must be connected to functional ground as prescribed. As a result, the intrinsically safe sensor circuits of CLS50 are also connected to ground. Therefore, the power supply of the transmitter must be galvanically isolated and connected to ground. The CM42 and CLM153 transmitters already have secure internal galvanic isolation and therefore safely separate the sensor circuit from the other circuits. 8 Endress+Hauser Indumax CLS50D/ CLS50 Incoming acceptance and product identification 3 Incoming acceptance and product identification 3.1 Incoming acceptance 1.

The sensor head must be completely immersed in the medium. 2 a max. 100 (3.94) 1 A0024950 1 1 2 a 14 Sensor orientation, dimensions in mm (inch) Direction of medium flow Minimum water level in the pipe Distance from pipe wall Endress+Hauser Indumax CLS50D/ CLS50 4.1.2 Installation Installation factor In confined installation conditions, the conductivity measurement is affected by the pipe walls. The installation factor compensates for this effect. The transmitter corrects the cell constant by multiplying by the installation factor. The value of the installation factor depends on the diameter and the conductivity of the pipe nozzle as well as the sensor's distance to the wall. The installation factor f can be disregarded (f = 1.00) if the distance to the wall is sufficient (a > 15 mm (0.59"), from DN 80). If the distance to the wall is smaller, the installation factor increases for electrically insulating pipes (f > 1) and decreases for electrically conductive pipes (f < 1). It can be measured using calibration solutions, or a close approximation determined from the following diagram. f 1.40 2 1.20 1.00 1 0.80 0 5 10 15 20 0.20 0.39 0.59 0.79 25 a [mm] 0.98 a [inch] A0005441 2 1 2 Relationship between installation factor f and wall distance Electrically conductive pipe wall Electrically insulating pipe wall 4.1.3 Air set CLS50D The digital sensor has already been adjusted at the factory.

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 25 Commissioning 6 Indumax CLS50D/ CLS50 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. 26 Endress+Hauser Indumax CLS50D/ CLS50 Maintenance 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 .
