Activation of the STO function
The STO safety function is triggered by the two redundant inputs SF1 and SF2. The
logical statuses of the two inputs in relation to the activation of the safety function
STO can be seen in Table 6.4.

Table 6.4 Logic for activation of the STO function
The response time of the STO function between activation of inputs SF1 and SF2
and activation of the safety function is
10
ms > response time > 6
ms
.
To prevent the STO function from activating when not wanted (e.g. due to OSSD
signals at the safety inputs), signal interrupts lasting <6 ms are ignored at safety
inputs SF1 and SF2. This means that STO is only activated when the signals at the
safety inputs are off for a period of >6 ms. The diagram below should clarify this.
