the priority of the ON_60 event in the Night Schedule (220) is lower than that of the ON_100
event in the Peak Time Schedule (210). The Night Schedule is therefore locked out until the
ON_100 event in the Peak Time Schedule ends at the conclusion of the evening peak time.

Once the ON_100 event in the Peak Time Schedule ends at the conclusion of the evening
peak time, the Night schedule executes its ON_60 event, setting the luminaire to 60%. The
luminaire remains at 60% until the morning peak time starts or sunrise, whichever comes first.

If the start of the morning peak time comes before sunrise, the Peak Time Schedule executes
its higher-priority ON_100 event at the start of peak time and fully illuminates the luminaire
to 100%. If the end of the morning peak time occurs before sunrise, the Night Schedule dims
the luminaire back to 60% once the Peak Time Schedule ends at the conclusion of the
morning peak time. The luminaire stays at 60% until the Day Schedule executes its
higher-priority OFF event at sunrise and turns the luminaire off.

If sunrise comes before the start of the morning peak time, the Day Schedule executes its
higher-priority OFF event at sunrise and turns the luminaire off.
The following graphic demonstrates the exception schedule with the events of the Day Schedule,
Peak-Time Schedule, and Night Schedule.
