Note
Malfunctions as a result of withdrawing and inserting components
Malfunctions can occur by withdrawing and inserting components that are used for Safety
Integrated without having to exit the fail-safe state. For example, PROFIsafe communication
is not reestablished after this event.
• Withdrawing and inserting components used for Safety Integrated (power units, Sensor
Modules, TM54F) in operation and in the deactivated state is not permissible. Activating
the components always requires a POWER ON.
Note
Approval of option K82
Only circuits that have been manufactured by the OEM or by certified factories or that have
been installed by the authorized service for option K82, possess an approval. Possible plant-
side reproductions by non-certified manufacturers do not possess this approval!
An up-to-date list of authorized factories is available on request from your local Siemens
office.
