Does anyone currently use a VFD for their central vacuum system? We are attempting to install one on our central vacuum system and had the following questions:
1. What VFD sensor are you using?
2. Where is the sensor mounted/located in the central vacuum system?
We have installed a Schneider sensor that is located at the base of the vacuum. It is a 0-10 volt analog input, but at max vacuum it reads about 7 volts, and when the vacuum is off it reads about 10 volts. This doesn't seem like a large enough range to work properly. We would like the vacuum to be running at the lowest hertz possible when no one is using it and ramp up to 60 hertz as the vacuum nozzles are pulled off to be used. I also am not sure if the placement of where the sensor is located will affect how sensitive the system is. Any assistance would be greatly appreciated!
