Behavior of the outputs in the event of enabled
switch-off delay for stop category 1
The affected outputs are only set to the safe state once the switch-off delay has elapsed.
The switch-off delay can be interrupted by switching the output on again.
The time until the outputs are actually switched off depends on the parameterization of the
switch-off delay and the event that causes the outputs to be switched off.
In the event of an error (excluding bus errors) the affected outputs are switched off
immediately (without delay). In this case, only stop category 0 is supported.

Once the set switch-off delay has elapsed
After a bus error
Yes
Once the set switch-off delay has elapsed
After a short circuit, cross-circuit, failure of
the supply voltage or hardware fault
No
Immediately (only stop category 0)
WARNING: Incorrect/insufficient safety distances
Selecting the wrong switch-off delay can result in incorrect safety distances being
designed.
•
When designing the safety distances, take the selected switch-off delay into
consideration.
