„ D – duration: Time period between “due” and “overdue,” specified
by the machine manufacturer.

measures must be performed and acknowledged.
„ t1 – time point “Maintenance measure will soon be due”:

„ t2 – time point “Maintenance measure is due”:
„ Starting from this time point, the maintenance measures should
be performed and acknowledged.
„ The status is marked in red.
„ Calculation: t2 = interval
„ t3 – time point “Maintenance measure is overdue”:
„ At this time point, the maintenance measures are overdue.
„ The status stays on red.
„ Calculation: t3 = interval + duration
