Patent ID: 8829736

Claim:
An electric circuit for remotely starting a center pivot irrigation system including a central pivot and a plurality of towers, the electric circuit comprising: a control panel positioned proximal to the central pivot and including access to an electric power source; a first cable connected to the control panel; a second cable connected to the control panel; a first transformer positioned proximal to the control panel and including a primary side coupled to a first voltage source with a first voltage and a secondary side presenting a second voltage, the first transformer configured such that the first voltage is greater than the second voltage; a second transformer positioned proximal to an outermost tower and including a primary side coupled to the secondary side of the first transformer with a third voltage and a secondary side presenting a fourth voltage, the second transformer configured such that the third voltage is less than the fourth voltage; a first relay positioned proximal to the outermost tower and including a first input, a first contact connected to the first cable, and a second contact connected to the second cable, the first input operable to change a connection between the first and second contacts; and a second relay positioned proximal to the outermost tower and including a second input, a third contact connected to the second contact, and a fourth contact, the second input operable to change a connection between the third and fourth contacts, wherein, when the center pivot irrigation system is started remotely, the connection between the first and second contacts is momentarily open, the connection between the third and fourth contacts is momentarily closed, and a circuit is formed with a conductive path that includes the secondary side of the second transformer and the second cable.
