Emergency Reverse: Enhanced Plug Braking Current
To implement this type of emergency reverse, the belly-button switch is wired to
a control relay that simultaneously selects "reverse" (regardless of the vehicle's
actual direction of movement) and "full speed"—as shown in Figure 10 by the
dashed line. The controller is designed (internally) to enhance plug braking
current when the emergency reverse input is connected to B+.
