| Hydraulics – safe and sound |
Field of application of functional safety according to EN ISO 13849 in hydraulic systems
|
|
EN ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems. In general, a control system consists of an input module (sensory system), a logic unit, and an output module (control block). The individual modules can be regarded as sub-systems enabling better limitation of technology transit.
As the machine manufacturer, you are responsible for the entire safety function. For each sub-system, a performance level (PL) or mean probability of failure (PFHd value) can be determined.
The overall probability of failure can be calculated by adding the PFHd values of the sub-systems.
