Abstract
A control system for controlling a shared variable frequency drive for operating more than one mechanical systems of a grain bin. The control system includes at least one processor circuit that is configured to operate the shared VFD in both a first mode, wherein operating in the first mode results in operating a fan assembly of the grain bin, and a second mode, wherein operating in the second mode results in operating an unload sweep assembly within the grain bin.
Claims19
A control system for controlling a shared variable frequency drive (VFD) for operating more than one mechanical systems of a grain bin, the control system comprising:
- at least one processor circuit that is configured to:
- operate the shared VFD in a first mode, wherein operating in the first mode comprises controlling a fan assembly of the grain bin, and a heating device coupled to the fan assembly, the heating device providing heat only when the fan assembly is blowing and inhibiting heating of the heating device until the fan assembly reaches a threshold frequency;
- and
- operate the shared VFD in a second mode, wherein operating in the second mode comprises controlling an unload sweep assembly within the grain bin.
A method of operating one or more mechanical systems within a grain bin, the method comprising:
- operating a shared variable frequency drive (VFD) in a first mode, wherein operating in the first mode comprises controlling a fan assembly of the grain bin with the shared VFD, and a heating device coupled to the fan assembly such that the heating device provides heat only when the fan assembly is blowing, and inhibiting heating by the heating device until the fan assembly reaches a threshold frequency;
- and
- operating the shared VFD in a second mode, wherein operating in the second mode comprises controlling an unload sweep assembly within the grain bin.
