398 Scheduling
The following graphic demonstrates the exception schedule with the events of the Day Schedule
(OTE). This exception schedule will be updated as the Night Schedule and Peak-Time Schedule
(OTE) exceptions are created.
Creating the Peak Time Schedule (One-Time Exception)
The Peak Time Schedule (OTE) turns on the luminaire and sets the brightness at 100%. Designing the
Peak Time Schedule (OTE) entails creating a one-time exception that recurs every weekday with the
following events:
1. An ON_100 event with a 210 priority that is scheduled to start at the beginning of the morning
peak time (07:00 in this example) and end at the conclusion of the morning peak time (09:00 in
this example). If or when this event actually occurs depends on the calculated sunrise time.

If the start of the morning peak time occurs before sunrise, the ON_100 event is executed and
brightens the lights from 60% to 100%. This is because the priority of the ON_100 event in
the Peak Time Schedule (210) is higher than that of the current ON_60 event in the Night
Schedule (220).

If the start of the morning peak time occurs after sunrise, the ON_100 event is not executed.
This is because the ON_100 event in the Peak Time Schedule has a lower priority (210) than
