CloudWatcher operated roll off roof

Many motor systems include a push button to open or close the roof. They typically require the button to be pushed for a short period of time, and that will trigger the roof to open if closed, or close if opened.

One safe way to have the CloudWatcher relay close the roof (but never open it) is explained in the following diagram. Apart from the CW itself, you just need a “roof opened” limit switch (that is, a switch that will be closed, active, when the roof is open) such as one of these:

The roof motor push button is connected, in series, to the limit switch and the CloudWatcher relay:

Please test – a few motors will not start moving until the button is released; for those this system will not work, so far we’ve found they are a minority.
