2 Objectives At the end of this exercise, you will be able to:

3 Define lighting scene and lighting zone. Demonstrate how to turn on and off multiple lamps with a single command. Demonstrate the soft off condition and show how to overcome it.

4 Implement simple lighting scenes using power line carrier (PLC) modules. Implement a simple two-zone lighting control system using power line carrier (PLC) modules.

5 About This Presentation We need to thoroughly know what lighting scenes and zones are. This is so our lighting system will work properly.

6 Some Background To power lights, we need electricity. But where does electricity come from?

7 And how many phases are produced? 1, 2, 3, 4? We need to know in case we run into problems.

9 Each generator has multiple sets of windings that produce electricity in three phases that are 120 degrees apart. The generators are phase-locked together so they’re producing AC electricity in unison. The 3 phases on a graph would look like this:

22 Rooms or Zones A zone is usually one particular room of a home. The next step is to control that lighting. That’s what scenes are all about.

23 Scenes A lighting scene is all about setting the mood or atmosphere of a room.
