OVERVIEW
Pivot Mounted Auto Reverse (Option)
The pivot mounted auto reverse option is shown for
the Standard Center Pivot in Figure 29-1 and the 2

Each switch has a back-up safety contact designed
to stop the machine if the reversing contact or associ-
ated circuitry fails to achieve the planned direction
change.
