•
A thorough check must be carried out during commissioning and following modifi‐
cations.
•
The regular thorough checks of the safety system must fulfill certain minimum
requirements. The minimum requirements for the thorough check of the safety
system comply at least with the sum of the minimum requirements for the thor‐
ough check of the components of the safety system (see operating instructions of
the components).
•
In many cases, depending on the application conditions, the risk assessment can
determine that further thorough checks are required.

Extension and modification
Expansion for additional safety functions
Additional safety functions can be implemented to trigger a safe stop 1 or safe stop 2.
The hardware of the safety system must not be changed when doing so.
For information on configuring additional safety functions, see
tional safety functions", page 49
Modification
Only the following modifications are permitted:
•
Activation of the safely limited speed function by an external or internal signal (
"External and internal signal for activating the safely limited speed", page 51
)
NOTE
Internal and external trigger signals for activating the SLS function or for integrat‐
ing additional safety functions may only be introduced at the points in the soft‐
ware provided for the respective purpose. Trigger signals and additional safety
functions must comply with the required safety level. It is the responsibility of the
user to provide proof that this is the case.
•
Activation of the override function (
see "Configuring the override function",
)
•
Relocation of input and output signals to inputs and outputs with the same func‐
tion on the same or a different module
WARNING
There is a risk of death or serious injury as diagnostics and shock resistance for
the protective device are not reliable.
b
Position inputs and outputs on different modules in such a way that they
have the same properties in terms of safety technology as the inputs and out‐
puts of the original module.
b
Adjust the current flow diagram accordingly (
see "Safety controller pin assign‐
).
