10.2 Maintenance Tasks
In normal operation, no maintenance tasks or configurations are necessary on the CMS. This
will only be the case if the CMS or its components fail.
Repeating System Tests
System tests are mandatory if:
• Parameters have been changed.
This applies to parameters with requirements that have to be checked during system tests.
• After completing a software update.
It is necessary to check whether the changes have an effect on the safety of the plant.
• Components connected to the CMS have been replaced
In this case, only the related system tests need to be carried out again.
The table for approving the system see chapter 12.2 Acceptance and Inspection
