Series Of Standards En 61508 (Vde 0803) - Siemens SINAMICS V90 Operating Instructions Manual

Safety Integrated function
8.1 Standards and regulations
The PFHD value of the safety-related controller is determined by adding the individual PFHD
values for subsystems.
The user has the following options when setting up a safety-related controller:
● Use devices and sub-systems that already comply with EN ISO 13849-1, IEC/EN 61508,
or IEC/EN 62061. The standard provides information specifying how qualified devices
can be integrated when safety functions are implemented.
● Develop own subsystems:
– Programmable, electronic systems and complex systems: Application of EN 61508 or
– Simple devices and subsystems: Application of EN 62061.
EN 62061 does not include information about non-electric systems. The standard provides
detailed information on implementing safety-related electrical, electronic, and programmable
electronic control systems. EN ISO 13849-1 must be applied for non-electric systems.
Note
Function examples
Details of simple sub-systems that have been implemented and integrated are now available
as "functional examples".
Note
EN 62061 and machinery directive
IEC 62061 has been ratified as EN 62061 in Europe and harmonized as part of the
Machinery Directive.
8.1.2.6

Series of standards EN 61508 (VDE 0803)

This series of standards describes the current state of the art.
EN 61508 is not harmonized in line with any EU directives, which means that an automatic
presumption of conformity for fulfilling the protective requirements of a directive is not implied.
The manufacturer of a safety-related product, however, can also use EN 61508 to fulfill basic
requirements of European directives in accordance with the latest conceptual design, for
example, in the following cases:
● If no harmonized standard exists for the application in question. In this case, the
manufacturer can use EN 61508, although no presumption of conformity exists here.
● A harmonized European standard (e.g. EN 62061, EN ISO 13849, EN 60204-1)
references EN 61508. This ensures that the appropriate requirements of the directives
are fulfilled ("standard that is also applicable"). When manufacturers apply EN 61508
properly and responsibly in accordance with this reference, they can use the presumption
of conformity of the referencing standard.
EN 61508 covers all the aspects that must be taken into account when E/E/PES systems
(electrical, electronic, and programmable electronic System) are used in order to execute
safety functions and/or to ensure the appropriate level of functional safety. Other hazards
(e.g. electric shock) are, as in EN ISO 13849, not part of the standard.
