Hauser 7
2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.
During operation:
‣
If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2.5 Product safety
2.5.1 State-of-the-art technology
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
international standards have been observed.
2.5.2 Electrical equipment in hazardous areas
ATEX/NEPSI II 1G 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.
