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 CLS15 Measurements in pure and ultrapure water Approved for Ex zone 0

Condumax CLS16 Measurements in pure and ultrapure water with hygienic requirements Approved for Ex zone 0

Condumax CLS21 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

• The sensors CLS15 / CLS16 / CLS21 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 CLS15-type sensors with non-metal process connections and the CLS21-type sensors
may only be employed for measurement in liquids with a minimum conductivity of
10 nS/cm.

• The CLS15-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.

• The maximum permissible cable length is limited by the maximum permissible
characteristic values of the transmitter: the total of the maximum permissible inductance L

i

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.

• When connected to the Mycom S CLM153 transmitter, the maximum permissible length of
measuring cables CYK71/CYK71-Ex or CPK9 is 16 m. When connected to the Liquiline M
CM42 transmitter, the maximum length is 50 m.

• Full compliance with regulations for electrical systems in hazardous areas (e.g. EN/IEC
60079-14) is mandatory when using the devices and sensors.

• If the specified medium temperatures are complied with, temperatures that are not
permitted for the respective temperature class will not occur on the equipment.

• With the exception of sensor version CLS15-*1M**, for functional reasons the CLS15
sensors may only be operated up to 120 °C (248 °F) during continuous operation / and up to
140 °C (284 °F) for short periods. The CLS15-*1M** version may only be operated up to
100 °C (212 °F) during continuous operation.

• For functional reasons, the CLS16 sensors may only be operated up to 120 °C (248 °F)
during continuous operation / and up to 150 °C (302 °F) for short periods.

The following connection values are safety limits which may not be exceeded when connecting
