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.

---|---|---|
EN ISO 12100-2 |
Start-up after failure of supply voltage / spontaneous restart |
The function block supports a start-up inhibit and restart inhibit of the function block after
You are responsible for planning and implementing the start-up behavior according to your risk analysis. To prevent an unintended start-up, 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.
NOTE:
Resetting does not occur with a negative (falling) edge, as specified by standard ISO 13849-1, but with a positive (rising) edge. |
ISO 13850 |
Positive opening operation |
Only use approved control devices, which conform to standard ISO 13850. |
ISO 13850 |
Using wires and cables as manual controls |
It is your responsibility to meet the requirements of this standard, according to the risk analysis you carried out. |
EN 60204 |
Safety of machinery |
The function block executes the stop categories 0, 1 and 2. |
