3.1.
DISPLAY BOARDS
The display boards are self-contained units which provide a visual display of sales infor-
mation (i.e., dollar amount, volume amount, unit prices). The actual display elements are
seven segment Liquid Crystal Displays (LCD’S). These elements are back lit with two
7W, field replaceable, fluorescent lamps to improve their visibility in low lighting condi-
tions. The LCD’s are soldered to their printed circuit boards; therefore, they are not
replaceable in the field.
The display board receives its data from the computer assembly. The decoding circuits,
and the drivers for the LCD’s, are located on the display board.
3.2.
LIGHTED CASH/CREDIT INTERFACE BOARD
The lighted cash/credit interface board performs two functions. First, is the switch
interface; that is all of the function and operational switch closures are sensed by this
board and then transmitted to the computer. Second, it supplies power to the lighted
buttons on the dispenser (push to start, cash/credit select). The transformer on the board
converts 110 VAC input to approximately 18 VRMS in order to power the switch lamps.
Located on this board is a fuse which fuses the AC input to the select board. If this fuse
should open, the push to start or cash/credit select switches will go blank; and the push to
start (or cash/credit select) and function switches will not work. Because the dispenser
requires that the push to start or a cash/credit select switch be pressed before it will reset,
the dispenser will not reset.
Once the select switch has been pressed the push-to-start signal must be received at the
push-to-start input connector J5 At nozzle on, if Pin 1 and Pin 2 are both open either
must be grounded and opened again for the dispenser to operate.
