Central Vac overload

Robert Green · 2010-03-30T11:23:04+00:00

Some of you might remember my question about building a silencing cabinetfor a central vac. Well, it worked, but too well. The problem is now thatif something gets stuck in the hose, we can no longer hear the immediateincrease in the motor load the way we used to. On occasion, the unit'smotor even shuts down from the overload.Does anyone have any ideas how to detect the "laboring" of the motor so Ican sound a chime or some other alarm when something clogs the pope - I meanpipe - the Pope has enough problems of his own. (-:I am going to try a test today with my Kill-0-Watt meter to see if there's asubstantial increase in current draw. I might be able to use a currentsensor to detect the upswing and sound a chime or some other kind ofwarning. I don't want to shorten the life of the motor by letting thethermal overload shut it down after it has overheated.Thanks in advance--Bobby G.Crossposted to follow up in AHR,please!

Same old moronic ideas.
