    SIL version may be used. SFC stands for “Safety Figure Calculated”. This desig- nation identifies AUMA products for which safety figures were calculated on the basis of FMEDA from field data and generic data (for detailed information refer to <Determ- ination of the figures>).

    3.3. Protection against uncontrolled operation (self-locking/brake) For self-locking AUMA gearboxes, it can be assumed that a load up to maximum torque will not result in uncontrolled operation from valve standstill due to valve torque load. Consequently, in these cases, further protection against uncontrolled operation is not imperatively required.

  • Page 8: Safety Instrumented Systems And Safety Functions

    Please note that safety figures only include the gearbox. Further components (e.g. Information integrity of external controls, actuators, valves ..) are not considered with the AUMA safety figures related to this product.

  • Page 9: Installation, Commissioning And Operation

    Gearboxes Installation, commissioning and operation Installation, commissioning and operation Installation and commissioning have to be documented by means of an assembly Information report and an inspection certificate. Installation and commissioning may only be performed by authorised personnel who have been trained on functional safety. 5.1.

  • Page 10: Tests And Maintenance

    This validation must include at least the tests referred to in chapters <Safety equipment: check> and <Proof test (verification of safe gearbox function>. In case a fault is detected during maintenance, this must be reported to AUMA Riester GmbH & Co. KG.

    Gearboxes Safety-related figures Safety-related figures 7.1. Determination of the safety-related figures The calculation of the safety-related figures is based on the indicated safety functions. Experience data and data taken from the exida database for mechanical components were used for hardware assessment. The PFD calculation should always be performed individually for each system using the parameters and conditions applicable for the respective system.
