Lighting Contactor Wiring Diagram With Photocell. Lighting contactors are relay switches that control the flow of electricity through a circuit powering the lighting in a given area. The photocell will come with a wiring diagram.
The ALION Photocell Switch automatically senses natural light. Now what you can do in order to make this work if your installing the photocell at the light itself is either leave the light switch on so that you have constant. By wiring the photocell to an analog input of your board you can read the voltage from it and see how it changes as the amount of light hitting the sensor changes too.
Describe any challenges encountered while working on project.
Use a screwdriver to loosen the terminal screws on the mounted contactor.
Photocells are sensors that allow you to detect light. Powerful WinControl software normalizes the Lighting control panel systems. I had a photocell on my exterior Christmas lights and if the cell was facing into the ground It would turn on much.
