  • Page 11: Definition

    SPECIFICATION OF THE SAFETY FUNCTION OPTISWIRL 4200 Homogeneous redundancy The degree of a functional safe device is determined by the accomplished qualitative safety integrity level and the quantitative hazard rate determined by the failure rate of the deployed hardware. If two or more identically constructed devices are used in parallel (device A is of the same type as device A’...

  • Page 12: Safety Reaction And Safe State

    SPECIFICATION OF THE SAFETY FUNCTION OPTISWIRL 4200 2.5 Safety reaction and safe state The vortex flowmeter reacts safely, as soon as a failure is detected by the output of the low or high failure current (safety reaction). As an additional feature, temporary and persistent failures can be distinguished: •...

  • Page 13: Operation
