6.3 Reset Function
When the safety function is activated, reset the safety
option. Depending on the configuration, the following
sources can reset the safety option:
•
•
•
•
Parameter 42-24 Restart Behaviour determines whether the
safety option restarts automatically, or waits for a manual
reset after the safety function was activated:
•
•
For more information, read the description of 42-31 Reset
Source and its options in chapter 7.1 Parameter List.
6.3.1 Reset Input (DI2)
If manual reset is configured, wire the DI2A reset input
terminal to a 24 V DC via an NO switch. The manual reset
can also be used to reset external errors detected by the
safety option.

The digital input on the safety option (DI2_A).
The reset signal via the safe fieldbus.
The automatic reset function.
Manual reset behaviour - when the safety
function is activated, the safety option requires a
reset from a reset source before it can run again.
Automatic reset behaviour - when the safety
function is activated, the safety option can run
again as soon as the condition that triggered the
safety function ceases. This behaviour is only
valid for the digital input where this reset
behaviour is defined. For instance, in case of an
external error, a manual reset from the reset
source is required regardless of the setting in
42-24 Restart Behaviour.
