Implementation of safety requirements from applicable standards

The safety-related function block has been developed according to the safety requirements (from applicable standards) listed in this section. All other requirements from these standards must be observed when implementing the safety-related function.

This section describes either how the function block meets the requirements of the standards or what measures need to be taken to meet the requirements of the standards.

Standards	Context/Requirement	Implementation
ISO 13856-1: 2013	Pressure-sensitive protective devices	Part 1: General principles for the design and testing of pressure-sensitive mats and pressure sensitive floors. Chapter 4.7: Response of output signal switching device(s) to the actuating force.
ISO 13856-2: 2013	Pressure-sensitive protective devices	Part 2: General principles for the design and testing of pressure-sensitive edges and pressure-sensitive bars. Chapter 4.11: Reset function.
ISO 13856-3: 2013	Pressure-sensitive protective devices	Part 3: General principles for design and testing of pressure-sensitive bumpers, plates, wires and similar devices. Chapter 4.2.6.3: Reset function. Chapter C.2.8: Result of sensor actuation.
EN ISO 12100-2	Start-up after failure of supply voltage/spontaneous restart	The function block supports a start-up inhibit and/or restart inhibit of the function block after start-up of the Sicherheitssteuerung or activation of the function block (S_StartReset = SAFEFALSE) the PSE that was previously triggered is no longer triggered (S_AutoReset = SAFEFALSE) You are responsible for planning and implementing the start-up/restart behavior according to your risk analysis. To prevent an unintended start-up/restart, you may need to perform an additional function start once the safety-related function has been reset. This will depend on both the results of the risk analysis and the signal path of the reset signal.
EN ISO 13849-1	Manual reset device	The Reset input supports the function of a manual reset device. Hinweis Resetting does not occur with a negative (falling) edge, as specified by standard EN ISO 13849-1, but with a positive (rising) edge. To implement the reset with a falling edge (with regard to the mandatory acceptance procedure), use the safety-related function block SF_Reset.
EN ISO 13849-1	Category B to 4	Single-channel or two-channel connection must be established depending on the category. Hinweis Cross-circuit monitoring is not performed by the function block. It is your responsibility to implement this monitoring function outside of this function block in the safety-related control system. For example, an appropriate function block (Equivalent or Antivalent) must be connected upstream for the purpose of using two-channel PSE.
EN 60204	Stop functions	The function block (S_PSE_Out enable signal) executes stop category 0.
ISO 13856	Start-up inhibit function	The function block supports a start-up inhibit and/or restart inhibit of the function block after start-up of the Sicherheitssteuerung or activation of the function block (S_StartReset = SAFEFALSE) the PSE that was previously triggered is no longer triggered (S_AutoReset = SAFEFALSE) You are responsible for planning and implementing the start-up/restart behavior according to your risk analysis. To prevent an unintended start-up/restart, you may need to perform an additional function start once the safety-related function has been reset. This will depend on both the results of the risk analysis and the signal path of the reset signal.
