96 Controlling a Street Lighting Network with the Scheduler Application
Creating the Weekday Daily Schedule
The weekday daily schedule turns on the lights at the start of the evening rush hour, dims them at the
end of the evening rush hour, brightens them at the beginning of the morning rush hour, and dims them
at the end of the morning rush hour. To create the weekday daily schedule, follow these steps:
1. In the Scheduler: Configure Web page, click the Daily Schedules icon. The Scheduler: Daily
Schedules Web page opens.
2. Click a Time box that is under any of the columns for Monday through Friday. The Edit dialog
opens.
3. Create each of the following events:
• At the beginning of the morning rush hour (for example, 05:00), an ON_100 event with a
priority of 255. This event fully illuminates the lights to 100% if sunrise has not yet occurred.
If sunrise has occurred already, this event does not execute because the exception schedule
has turned off the lights at sunrise using a higher priority event, which locks out this lower
priority event.
• At the end of the morning rush hour (for example, 09:00), an ON_60 event with a priority of
255. This event dims the lights to 60% if sunrise has not yet occurred. If sunrise has occurred
already, this event does not execute because the exception schedule has turned off the lights at
sunrise using a higher priority event, which locks out this lower priority event.
• At the beginning of the evening rush hour (for example, 17:00), an ON_100 event. This event
turns the lights on and fully illuminates them to 100% once sundown occurs, if the evening
rush hour is ongoing.
o If the start of the evening rush hour occurs before sundown, the ON_100 event is not
executed until sundown. This is because the ON_100 event in the weekday daily
schedule has a lower priority (255) than that of the OFF event in the weekday exception
schedule (220), which does not end until sundown. Once the OFF event in the weekday
exception schedule is executed at sundown, the ON_100 event is executed and the lights
are turned on and fully illuminated to 100%.
o If the end of the evening rush hour occurs before sundown, the ON_100 event is never
executed. This is because the weekday daily schedule executes an ON_60 event with a
priority of 255 at the end of the evening rush hour. The ON_60 takes precedence by
virtue of it being the most recent event between two events with the same priority.
