Condumax CLS15D/16D/21D Basic safety instructions
Endress+Hauser 5
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.
• Measuring point faults may be repaired only by authorized and specially trained personnel.
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 conductivity sensors are designed for the conductive measurement of the conductivity of
liquids.
They are used in the following fields:
Sensor Applications Hazardous areas
Condumax CLS15D Measurements in pure and ultrapure water Approved for Ex zone 0
Condumax CLS16D Measurements in pure and ultrapure water with hygienic requirements Approved for Ex zone 0
Condumax CLS21D Measurements in media with medium or high conductivity Approved for Ex zone 0
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 Operational safety
1. Before commissioning the entire measuring point, verify that all connections are
correct. Ensure that electrical cables and hose connections are undamaged.
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
ATEX / NEPSI II 1G Ex ia IIC T3/T4/T6 Ga, IECEx Ex ia IIC T3/T4/T6 Ga
• The Memosens inductive sensor-cable connection system is suitable for use in hazardous
areas in accordance with EC type examination certificate BVS 04 ATEX E 121 X. The
corresponding EC declaration of conformity is part of this document.
• The certified conductivity sensors CLS15D/CLS16D/CLS21D may only be connected via the
measuring cable CYK10-G/I*** to the certified intrinsically safe digital sensor output
circuits of measuring device Liquiline M CM42-KE/F/G/I/J********** in accordance with
EC type-examination certificate TÜV 13 ATEX 7459 X.
• 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 CLS15D-type sensors with non-metal process connections and the CLS21D-type
sensors may only be employed for measurement in liquids with a minimum conductivity of
10 nS/cm.
• The CLS15D-type sensors with non-metal process connections may not be operated under
process conditions in which electrostatic charging of the sensor, and particularly of the
electrically insulated outer electrode, is likely to occur.
• Measuring cable CYK10-G/I*** and its terminal head must be protected against
electrostatic charging if it is run through Zone 0.
• The maximum permitted cable length is 100 m.
• Ex versions of digital sensors with Memosens technology are indicated by an orange-red
ring.
• Full compliance with regulations for electrical systems in hazardous areas (e.g. EN/IEC
60079-14) is mandatory when using the devices and sensors.
