refer to the manufacturer’s instructions.
POWER AC DISTRIBUTION BOX
The power distribution box is where the 120VAC input
voltage is broken down to the main operating voltages
of the vender (24 VAC and 12 VAC) by a transformer.
Those voltages are sent to the controller via the P1 (3
pin) connector. It also contains a 15 Amp Outlet
which provides power to the Refrigeration Unit. It
contains a main power switch/plug that allows power
to the AC Distribution Box to distribute AC power to
the lights, evaporator fan, and refrigeration system,
which are always energized when the vender is
powered up. It is located inside the service area,
mounted to the back wall.
VENDING MACHINE CONTROLLER (VMC)
The vending machine controller is the heart of the
Glass Front Vender and is located on the rear wall
inside the service area. It is flash programmable and
may or may not include the program chip (EPROM),
which controls all aspects of the vender. It also
contains the power supply which regulates the
voltages required to operate the motors as well as the
coin mechanism, digital display, and all logic functions
in the vender.
Keypad
The keypad is located on the front of the service door.
It consists of a 6 inch X 3 inch matrix, tactile feel
membrane switch pad and an overlay. The pad
utilizes the letters A thru F on the left side and
numbers 1 thru 0 along with the symbol and Clr to
the right. The keypad is where the vender
programming is accomplished and where the
customers make their selections.
DIGITAL DISPLAY
The digital display is located directly above the
keypad on the front of the service door. It is used to
convey information to the consumer as well as to the
person programming the vender.
REFRIGERATION SYSTEM
The refrigeration system is a single piece unit and is
hermetically sealed. The Model DN2008-C consists
of a 1/3 plus horsepower compressor, with a single fin
and tube style condensing unit with one condenser
fan, condensation overflow pan, evaporator, and
evaporator fan motor. The refrigeration unit is located
behind the refrigeration unit cover panels, mounted in
the bottom of the cabinet. This unit is designed for
easy removal and replacement from the front or rear
of the vender as a complete assembly. An electronic
thermostat regulates the cabinet temperature. The
control of the thermostat is attached to the evaporator
coils and reads the temperature of air being pulled in
to the evaporator coil.
SHELF ASSEMBLY
Typically, there are 5 shelf assemblies in every
vender; however, this can vary depending upon the
configuration specified at the time of ordering. Each
can/bottle shelf consists of 9 columns. Each shelf is
capable of holding a variety of packages. The shelf
assembly consists of the tray, where all of the
following parts are mounted: Double Gate assembly,
and the slide/pusher assembly. These items are
discussed in detail below.
DOUBLE GATE ASSEMBLY (Can/Bottle
Trays)
The double gate assembly is mounted on the front
portion of the tray assembly and contains the vending
mechanism. Incorporated in the gate assembly are
the front and rear knuckle assemblies as well as the
product kicker. In standby operation, the front knuckle
is in the blocking position, which holds the front
displayed product in position to be vended. The rear
knuckle assembly is in a flat position, which allows
product to enter the gate area, and the kicker is flush
to the rear knuckle assembly. A stainless steel pin is
inserted through the rear most portion of the front
knuckle assembly and connects to a gear box below
the tray. When a selection is made, the plunger
pushes the lever toward the back of the tray. At the
same time the front knuckle is opened into a flat
position, the rear knuckle is closed to a blocking
position, holding the remaining product out of the gate
area, and the kicker is extended to firmly push the
front displayed product off of the tray. The plunger is
energized for approximately 1-½ seconds to allow
ample time for the displayed product to be ejected
from the shelf. The plunger is then released and the
front knuckle returns to the blocking position, the rear
knuckle and kicker return to their standby position and
the next product slides into the vend display position.
SLIDE/PUSHER ASSEMBLY (Can/Bottle
Trays)
The slide/pusher is located on the bottom of each
product column. Its purpose is to provide a slick,
friction resistant surface for the product to rest on.
The tall product pusher is mounted on the top of the
slide and incorporates a coil spring in the body that
attaches to the bottom of the slide through a slit. This
spring adds needed tension to insure that all products
in the column remain tight against each other and are
allowed to progress into the gate area. Periodic
cleaning and lubrication of the slides is recommended.
DO NOT USE SOLVENTS OR ABRASIVE
MATERIALS TO CLEAN ANY PORTION OF THE
TRAY.
