Page 2: General Precautions
1. General Precautions The system must be used only in accordance with the required protection level. The sensor must be protected against accidental knocks and used in accordance with the instrument’s ambient characteristics and per- formance levels. Sensors must be powered with non distributed networks. For outdoor installations or with cables longer than 30 m*, proceed as indicated at paragraph 3. -

5. Functional Safety (content according to IEC/EN 62061 paragraph 7) 5.1 Application The pressure sensor KH performs the following safety function: correct reading and transduction of pressure to individuate overpressure. Reading and transduction is considered cor- rect when it is within the specifications declared in the datasheet and in the Operating Manual. The SIL parameters of the transducer are shown in the table below: Parameter Value... -
Page 7: Restrictions Of Use
5.2 Restrictions of use The device must only be used in accordance with these operating instructions for mechanical installation, electrical con- nection, environmental conditions and use in order to maintain the declared SIL. The sensors must be powered by non-distributed networks and in any case with a length of less than 30 m. -
