Learn mode will need to be used following the
installation of the conversion kit, the linear sensor
or its mounting bracket, or the shot controller.
The IPH units are programmed at the factory so
Learn mode will not need to used prior to pouring.
Learn mode enables the shot controller to learn the
left-most and right-most piston positions. To do this, the
standard piston controls are disabled and the piston is
moved left and right using the top soft key. With Learn
mode enabled the top soft key icon will be a left or right
arrow to signify the direction the piston will move when
pressed. In the usual bottom soft key icon location, the
left-most and right-most piston positions obtained from
using Learn mode will be shown.
