1 . Power Supply . The 120 VAC power cord from the wall out-
let comes into the machine and plugs into the back of the
main junction box located on the bottom right side of the
cabinet. The voltage output to the board is 24 volts and is
plugged in the top right corner (P1 position).
2. Changers. The Snackshop LCM can use a variety of either
Coinco or Mars changers. The machine is wired for only 24
volt models. The changers available are Coinco (9302L or
9302LF) and Mars (TRC-6010 or TRC-6010XV). In addi-
tion, control boards support MDB (Multi-Drop Bus) periph-
erals which include coin mechanisms, validators and card
readers. MDB harness is P/N 680576.
3. Controller Board. This module is located on the inside
door (above selector panel) of the vending machine. The
controller will gove rn all vending activity within the
machine. It has the capability of driving eighty/selections.
4. Mode Switch. The Snackshop LCM has only one mode
switch that allows control of the machine functions. It is
located on the control board.This switch will allow 6 modes
of operation.
1. Operate (vending mode)
2. Change payout
3. Accountability
4. Price setting
5. Test vend
6. Vend option
5. Operate Mode. The operate mode is when the machine is
in the normal customer vending mode. The following steps
explain the operation and sequence of events when mak-
ing a vend.
a.Digital Display. During standby with no credit in machine,
the digital display will show all zeros with a designated
decimal point. When an alpha-nu m e ric character is
pressed, this selection will be displayed.
b. Credit Operation. Credit may be accumulated through
either a coin changer or bill validator mechanism. Credit
acceptance will disable when the accumulated credit
equals or exceeds the highest priced item. If using an
executive or “Protocol A” type coin mechanism, credit
acceptance is controlled by the changer. The bill valida-
tor will be enabled when a combination of nickels and
dimes, or nickels and quarters are available in the chang-
er.
c. Vend Process. After a keypad entry is made, the con-
troller will determine if sufficient credit is available and
the status of the selection. If the accumulated price and
the motor is present, a vend attempt will be made for that
selection.During this time, the selection will be shown on
the display. If credit is less than the selection price, the
price will be flashed for 3 seconds or until an alpha key
NOTE: Only one changer harness should be plugged
into the board for proper operation
is pressed. If the motor is flagged as bad, the selection
and the “MAKE ALTERNATE SELECTION” LED will be
flashed for 3 seconds or until an alpha key is pressed.
d. Change Payment. Following a successful vend, the
amount of change to be returned will be displayed for 2
seconds or until all coinage is paid back. A least coin
payout algorithm will be implemented.
e. Use Correct Change LED. If the changer’s least value
coin tube is empty, the “USE CORRECT CHANGE” LED
will be illuminated continuously.
