Switch test – Use this screen to verify operation of
the dispense switches and the nozzle detect switch-
es. With nozzles loaded in each station, and the door
closed, the view of the door on the screen should have
4 green dots at the lower portion indicating the nozzle
detect switches are pressed. From this view, you can
also push each dispense switch to verify operation. As
a switch is pressed, the circle above the switch on the
screen should light green.
Display connections – This screen is a simple diagram
showing the electrical connections to the connector
board on the display. Use this to confirm all harnesses
are properly connected.
Display touch test – Use this screen to test the touch
sensor on the display. As you touch the screen in
different places, green boxes should appear at each
point where you touch.
