Center Pivot 7000, 8000, 8120 Series 27
OVERVIEW
End Gun and Stop In Slot Control - Electronic (Option)
The Valley Control Panels use one of the following
options: encoder, a resolver or Valley GPS position
to determine the position of the pivot in the field. The
field position readings are used to turn the end gun
on and off or to stop at the stop in slot position.
Encoder or Resolver
The encoder and resolver options are installed in the
collector ring. See Figure 27-1.
As the pivot rotates, the collector ring turns which
also turns the shaft of the encoder or resolver. The
encoder or resolver send signals to the control panel.
The Control Panel uses the signal to determine field
position in degrees.
Valley GPS Position (Option)
The Valley GPS position option is usually installed at
or near the end of machine. See Figure 27-2.
When the machine is on, Valley GPS receives satel-
lite position data and sends raw coordinates to the
control panel.
The control panel uses the raw coordinates to deter-
mine field position in degrees.
Public Power Towable (Option)
The public power towable option includes electrical
receptacles mounted on each pivot pad and electric
cords with plugs wired into an electrical box mounted
on the pivot point. See Figure 27-3.
