2 Introduction to the instrument Cedex Bio System
System status
Interval For most maintenance actions a fixed maintenance interval is defined. (You cannot
change this interval.) This is the basis upon which the system calculates the date when
the actions need to be performed.
The interval timers and counters are reset whenever you confirm that the
maintenance action has been performed.
Maintenance actions without predefined intervals are performed whenever
necessary, or they are triggered by another maintenance action.
Due date The due date is the last possible maintenance day. This is the date you see when you
check the status of maintenance actions.
Ensuring smooth operation Performing all due maintenance actions during the daily Prepare or End Shift phase
ensures that routine operation does not have to be interrupted for performing
maintenance actions.
System status

various parts and processes:

covers or place sample tubes.
