It is classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts and/or by their reliability. ISO 13849-1:2006 Example 3. Safe stop in upper position by clamping and one-sided pressurizing (Category 3, Category 4 attainable), possible PL a-e. Positive assessment by IFA Clamping unit 2A can be released by valve 2V with supply pressure at pressure switch 2S1 and a control system 2S2. Non-return valve 1V1 avoids exhausting on pressure drop.
