￭ Relevant failure modesRelevant failure modes are:• the FSO module detects any open circuits, short circuits and redundancy failures of thePOUS input signal wirings. Similarly, it detects redundancy failures of the POUS switchwhen the POUS request is on.• internal failures of the FSO and FSE modules and the STO function in the inverter unit.These failures are included in the failure rate value of the function.￭ Fault exclusionsFault exclusions (not considered in the calculations):• any short and open circuits in the cables of the safety circuit• any short and open circuits in the cabinet terminal blocks of the safety circuits.￭ Operation delaysTotal delay for the POUS function: (less than) 500 msAmbient conditionsFor the environmental limits for the safety functions and the drive, refer to the hardwaremanual of your drive.Related standards and directivesNameStandardSafety of machinery – General principles for design – Risk assessment and risk reductionEN ISO 12100:2010Safety of machinery – Safety-related parts of control systems – Part 1: General principlesfor designEN ISO 13849-1:2015Safety of machinery – Safety-related parts of control systems – Part 2: ValidationEN ISO 13849-2:2012Safety of machinery – Prevention of unexpected start-up (ISO 14118:2017)EN ISO 14118:2018Safety of machinery – Electrical equipment of machines – Part 1: General requirementsEN 60204-1:2006 +AC:2010IEC 60204-1:2016Electrical equipment for measurement, control and laboratory use - EMC requirements- Part 3-1: Immunity requirements for safety-related systems and for equipment intendedto perform safety-related functions (functional safety) - General industrial applicationsIEC 61326-3-1:2017Functional safety of electrical/electronic/programmable electronic safety-related systems- Part 1: General requirementsIEC 61508-1:2010Functional safety of electrical/electronic/programmable electronic safety-related systems- Part 2: Requirements for electrical/electronic/programmable electronic safety-relatedsystemsIEC 61508-2:2010Functional safety – Safety instrumented systems for the process industry sector – Part1: Framework, definitions, system, hardware and application programming requirementsIEC 61511-1:2016Adjustable speed electrical power drive systems – Part 5-2: Safety requirements –FunctionalEN 61800-5-2:2007IEC 61800-5-2:201636 Technical data
