Indumax CLS50D/CLS50 Basic safety instructions

2 Basic safety instructions

2.1 Requirements for personnel

• Installation, commissioning, operation and maintenance of the measuring system may be carried out only by specially trained technical personnel.

• The technical personnel must be authorized by the plant operator to carry out the specified activities.

• The electrical connection may be performed only by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions and must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained personnel.

Repairs not described in the Operating Instructions provided must be carried out only directly at the manufacturer's site or by the service organization.

2.2 Designated use

Indumax CLS50D or CLS50 sensor is particularly suitable for use in the chemical and process technology sectors. The six-decade measuring range and the excellent chemical resistance properties of the materials in contact with the medium (PFA or PEEK) make it possible to use this sensor in a wide range of applications, such as:

• Concentration measurement of acids and bases

• Quality monitoring of chemical products in tanks and pipes

• Phase separation of product/product mixtures

The digital sensor CLS50D is used in conjunction with the Liquiline CM44x/R or Liquiline M CM42, while the analog sensor CLS50 is used with the Liquiline M CM42 or Liquisys CLM223/253.

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 Workplace 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 international standards for industrial applications.

• The electromagnetic compatibility indicated applies only to a product that has been connected in accordance with these Operating Instructions.

Sensors with TIIS approval (CLS50D-TA****, CLS50-T***)

Sensors with TIIS approval may only be used in a Zone 1 (2G) environment.

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.
