VFD Filter Connection
Connecting a VFD Pump in the same power circuit as the LX-IVM Controller
makes it prone to electrical noise having undesirable behavior. Symptoms
can include inconsistent operation of the stations and inability read flow
from a compatible flow sensor. Rain Bird recommends the following
modification to the controller to “filter out” the noise from the VFD and
ensuring normal operations of the Controller.
