Behavior of the Outputs in the Event of Enabled Switch-
Off Delay for Stop Category 1
Depending on the event that causes the outputs to be switched off, the parameter-
ization of the switch-off delay the time until the outputs are actually switched off can
vary.
For the switch-off operation, please take into consideration the following:
•
The switch-off operation can be interrupted by switching the output on again.
•
If the parameterization of the module is modified, the modified
parameterization does not take effect until all the outputs have been switched
off.
If the parameterization is modified before the switch-off operation is
complete, diagnostic message 02F2
hex
is generated.
•
Carry out a validation every time the parameterization is modified.
•
Please note that when the parameterization is modified, this can result in
delayed startup due to the switch-off delay time.
Disconnection of outputs
Influence of
parameterized
switch-off delay
Disconnection of outputs
•
By the safe controller
Yes
After the parameterized switch-
off delay has elapsed
•
After a bus error
Yes
After the parameterized 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)

parameterization
Delayed shutdown when using stop category 1
For stop category 1 please take into
consideration the following:
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.
Incorrect design of safety distances due to
incorrect calculation of the overall shutdown
time
When designing the safety distances, please take into consideration the parame-
terized switch-off delay time.
