introduction
The APi 120/320 features the MasterVend Control System and MasterMenu system which provide a user friendly menu
to setup and configure the machine. The simple operation and built in flexibility of this system allows each user to
customize the menu system to their preference. The system can be configured to display service and operational mode
messages in any of six different languages and support up to 110 selections. Robust testing capability as well as
extensive diagnostics and error reporting facilities are built in to provide ease of maintenance.
The APi 320 Series machine is designed to be used as a refrigerated or frozen, pre-packaged food merchandiser.
Changing the machine between refrigerated and frozen is accomplished by choosing between food or frozen on the
LogiCenter (LCB) board. In addition there is a default setting (jumper) on the Food Driver Board (FDB) to ensure that if
the FDB should loose communications with the LCB, the refrigeration unit will maintain the temperature of the default
setting, refrigerated or frozen. All APi 320 series machines are companion machines and are dependent upon a Control
module or 120 series snack merchandiser to control the machine.
The Control module is a cabinet that mounts to the right side of the API 320.The Control module contains a power
supply, LogiCenter board (LCB), selection keypad, coin mech and any other peripherals. The Control module is capable
of supporting up to two machines. When two machines are attached to one Control module, each machine has the
capability of being set up independently as a food or frozen.The APi 120 Series snack machine is capable of supporting
one 320 Series merchandiser.

unpacking
The APi 320 Series is assembled and packed so that a
minimum amount of time is necessary for preparation to
install it on location. The following steps are
recommended to insure correct unpacking.
1. Shipping Damage: Thoroughly inspect the exterior of
the carton for damage which may have occurred
during shipment. Report any damage to delivering
carrier and follow their instructions.
2. Remove staples from lower edge and those at top of
carton, and slit carton vertically at the taped corner.
Open and remove carton. Remove the remainder of
the packing material. On machines shipped with lock
in place, the keys are taped inside the coin return.
3. Remove Vendor With A Fork Lift Truck:
Remove the carton from the vendor. From the front of
the vendor tip the vendor backward and run forks
under the cabinet.
4. Removing Vendor Without A Fork Lift Truck:
Remove the carton from the vendor. Break off the thin
piece of board behind the rear legs. From the front of
the machine tip the vendor back enough to clear the
lower legs from the holes in the front board. Push
the machine back off the base. Remove the pallet.
NOTE: Because the weight concentration is
toward the back of the cabinet, trucking and lifting
should be done from the back. CAUTION should
be taken when trucking from side .
5. On machines with lock in place, unlock, and turn
handle to open door. When no lock is furnished,
remove tape and turn handle. Swing door to its full
open position.
6. Remove all packing tape and paper from various
areas of machine and the shipping strap.
7. Warranty: The warranty card is attached to the cover
of this manual. It must be filled out in full and mailed
at once to insure coverage.
◆IMPORTANT: A set of anchoring brackets are sent
with each machine. The kit is located in the bottom of
the machine complete with instructions. It is
recommended that this kit be installed to prevent shifting
of the machine.
8. Air Deflector: Remove the air deflector from the
delivery bin. Loosen to four screws holding the screen
on the back of the machine, place the slotted holes in
the air deflector over the screws and push down,
re-tighten the screws.
CLEANING & MAINTENANCE
The 320 Series Merchandiser will do the best
merchandising job for you if it is kept clean.The amount of
cleaning your machine will require will vary from location
to location depending on the environment. We suggest
that a thorough cleaning be preformed at least twice a
year in a clean environment, in addition to this, light
cleaning that should be performed each service. The
display windows can be cleaned with any good glass
cleaner. The exterior and interior surfaces should be
cleaned with warm water and mild detergent (food grade).
Rinse thoroughly and dry all surfaces. Always use a clean
lintless disposable towel for cleaning.Their is an option
in the software to preform a manual defrost (see the
operating system section of this manual for instructions ).
The main product shelves can be best cleaned with the
spirals and product spacers removed. Refer to page 1.03
for removal of spirals and removal of the product spacers.
Clean the acceptor on the changer frequently as
accumulated dirt in this area can cause coins to hang or
not be accepted. Follow recommended cleaning
procedures as described by the manufacturer.
◆It Is extremely important that the air intake screen for
the refrigeration unit is cleaned weekly and that no
product is stored in this machine blocking this screen
or the condenser unit.This screen is located toward the
front and center of the machine floor.

1.02
Leveling the Machine on location is important for the
machine to function properly. The four leveling screws in
the legs are the means of leveling the machine. After
positioning the machine, level machine in front to rear and
right to left directions. After leveling, turn front right (lock
side) leveling screw in about one-half turn to drop this
corner slightly to make the door easier to close and lock.
Voltage and Polarity Check. It is important that this
machine is hooked up to the proper voltage and polarity.
Using a voltmeter, perform the following checks from the
illustration below.
◆NOTE: It is imperative that the machine is on it’s own
20 AMPERE SERVICE. Only the Control module may be
plugged into the same service.
NOTE: Should the readings be different from above,
have a certified electrician correct the problem.
For Health reasons it should be noted that cold
(refrigerated) or frozen vending machines are designed
for short term storage of already refrigerated or frozen
product. The definitions for cold and frozen machines are
as follows:
1. Cold is defined as 41°F (5°C) or lower for cold food.
All food in a Refrigerated machine must have a
product expiration date on the package. See your
product suppler for specifics on date codes and
expiration dates.
2. Slack is defined as a frozen machine set below 15°F
(-9°C) or lower for slacking precooked frozen food.
3. Frozen is defined as 0°F (-18°C) or lower for frozen
food. Items used in a frozen machine should have
frozen designated packaging.
When installing a machine, the machine should be
allowed to pull down to operating temperature before
loading product into the machine, approximately 1 hour
for a cold machine and 2 hours for a frozen machine.
See blue page 3.01 for instructions on setting temperature.
For more information on pull down times and health
control see page 2.03 of the components section of this
manual.
Loading Shelves. Open door to full open position, push
down on the two plastic lock levers on right and left side
panel by shelf to unlock shelf, holding lever down. Grasp
the shelf, under both front corners, lift front shelf slightly
and pull forward until shelf reaches its stop. The shelves
tilt down (do not drop) to make loading easier. Only one
product shelf should be in the loading position at a time.
When returning a shelf, be sure the shelf is in its full home
or vend position. Begin loading
with the top shelf. Move it to the loading position.The
height spacing for items is greatest in this shelf and the
tallest items should be placed there. Soft items, should
be placed in the lowest shelf, making the drop distance
as short as possible.

1.03
IMPORTANT: Product must not be forced into the spiral
spaces but should fit freely. If the product is too tight, use
a larger pitch spiral. The bottom of the product should be
placed on top of the spiral wire that rests on the shelf
surface.
Vending Large Products
The 320 Series can be configured to use two spirals to
vend one product.The motor to be paired will be called
the left motor, and must be an even numbered motor. Any
even numbered motor may be paired.This motor must
always be paired to the odd numbered motor next in
sequence (i.e. motor “110” will always be paired with
motor “111” and “114” always with “115”). Only motors in
the same row of the machine can be paired. For more
information on Motor pairs see the operating system
section of this manual.
Adjusting the Stopping Position of the Spiral.
One primary difference that distinguishes the new motors
from previous motors is the presence of an eight sided
star at the drive hub of the motor. This permits the
stopping position of the spiral to be customized by the
operator to ensure the best possible delivery of product.
To change the stopping position of the spiral, remove the
spiral lock from the motor by pinching the shaft of the
spiral lock from the back side of the motor and pulling
forward on the front side of the spiral lock.The spiral lock
can be reinstalled in any of eight different positions by
turning the spiral lock to the position desired and pushing
the shaft of the spiral lock through the eight sided star at
the drive hub of the motor.
Removal of Spiral. Grasp the front of the spiral and turn
it clockwise for an even numbered selection and
counterclockwise for an odd numbered selection. Lift the
spiral up and off of the spiral lock. When replacing a spiral
attach it around the tab on the spiral lock and turn the
spiral to lock it in place. Be sure the front end of the spiral
is positioned properly. (see Figure 3). The spiral lock is
attached between the spiral retainer tabs. Give a light
forward pull on front of the spiral to check it is locked in
place.
Product Spacers
A product spacer is used to reduce the width of the
product area and can be used on any shelf . Spacers
should fit within 1/8” of the product but should not fit tight
against the product. There are four positions in each
column where these spacers can be placed. To install the
spacer, lift upward on the front of the spacer, align the lock
ear on the rear of the spacer with the slot on the rear of
the cabinet, push the spacer downward aligning the three
tabs on the lower edge of the spacer with the three sets
of slots on the shelf bottom. Pull the spacer forward to lock
in place.
Lock Product Shelves. After all the product has been
loaded be sure all shelves are returned to their vend
position behind the front roller guides.
Install Proper Price Tabs into price tab holder for each
selection in the main product area.

Control module Installation Instructions.
A. Remove the 3 hole plugs from the top, inside right
corner of the 320 cabinet. Once removed, remove the
foam insulation (pre cut) behind the holes.
B. Locate the front and rear lower support brackets on
the bottom right hand side of the 320 cabinet. (These
brackets have already been installed at the factory.)
There should be a 1/8” space opening between the
cabinet side and the mounting bracket, these
mounting brackets can be adjusted by loosening the
2 outside bolts from each of
the leg weld’s on the lock side of the cabinet.
C. Move the base of the Control module close to the 320
cabinet so the bottom left edge of the Control module
rests on the support bracket.Tip the Control module
to an upright position.
D. Install the upper mounting plate using the 1/4-20 kept
nuts provided. Install three in the refrigerated cabinet
and Three in the control module.
E. Put the insulation and plugs back into the 3 holes in
the refrigerated cabinet.
F. Locate the interconnect harness (communications
cable) coming out of the back of the 320 and route it
into the back of the Control module to the LogiCenter
board and plug into the P8 connector (MDB). When
using a MDB coin mech and/or bill validator these
peripherals must be plugged into the pig tail coming
off of the communications cable. The machine
attached to the Control module is considered Cabinet
1.
G. Level the Control module to the machine by adjusting
the leg levelers.
◆NOTE: Because the Control Module is top heavy
and unstable, always use two people when attaching
the it to the 320.

Temperature Monitoring
To display the temperature of all food and/or frozen
cabinets in an installation depress and hold the “C” (for
temperatures to be displayed in Celsius) or “0” (for
temperatures to be displayed in Fahrenheit) button on the
front panel keypad. After three seconds, the temperatures
(in all refrigerated and frozen cabinets present in the
installation) will display for three (3) seconds and continue
to do so until the button is released.
The Refrigeration System
The refrigeration system is comprised of a 3/4 horse
compressor and is a hermetically sealed system (no
service ports).The refrigerant used in the refrigeration
system is 404a and the charge is 28 ounces. The
Compressor is turned on and off by a relay contained in
the refrigerated cabinet junction box.This relay is
energized by the Food Driver Board (FDB).The
temperature sensor is plugged into the P2 connection of
the FDB. The entire refrigeration assembly comes out in
one piece by removing the two screws (to the right of
the condenser) fastening the refrigeration assembly to the
cabinet bottom.
◆CAUTION: Because of the weight of the refrigeration
assembly it should be removed by two people.
Refrigeration Control
The refrigeration system in the APi 320 cabinets is
controlled by the Electronic control system (ECS)
according to the temperature range selected by the
operator in the MasterMenu system.The temperature
readings from the temperature sensor is accurate to 1ß F.
The temperature sensor data is monitored and the
readings averaged over time. The cabinet temperature is
checked once every 5 seconds. Using the Set
Temperatures menu item, the cabinets may be designated
as Ambient, Food, or Frozen.When a cabinet is
designated as Ambient, the Control System will not control
the temperature in that cabinet and the refrigeration
system in that cabinet will be disabled if it exists.
Temperature readings will still be available for cabinets
designated as Ambient.When a cabinet is designated as
Food or Frozen, the Control System will attempt to
maintain the temperature in the cabinet to within 3° F of
target temperatures specified in the Set Temperatures
menu item during normal operation (this is fixed at 36°F
(2°C) for Food and is settable from -15°F to +10°F (-26°C
to -12°C) for Frozen). To accomplish this, the refrigeration
unit will be turned on when the temperature exceeds the
appropriate target temperature by more than 3°F for 3
seconds during normal operation.The refrigeration unit
will then remain on until the temperature falls 3° below the
target temperature for 3 seconds.
Health Monitoring
The APi 120 and/or Control module allow for accurate
monitoring of all refrigerated and/or frozen cabinets in the
installation.This also allows for shutdown of each cabinet
individually by the machine without impact to the others.
When the machine shuts down a cabinet due to an out of
tolerance temperature, the light in that cabinet is turned
off, all selections in that cabinet disabled, and the display
updated to indicate “CABINET X OUT OF SERVICE”
(where “X” is “1” if the temperature sensor in Cabinet 1
detected the out of tolerance condition, or “2” if the
temperature sensor in Cabinet 2 detected the out of
tolerance condition). A temperature sensor is present in
each refrigerated and/or frozen cabinet.The Pull down
period describes the time elapsed between a cabinet
Power Up (Door Closed) and the point in time when the
cabinet temperature first reaches the target temperature.
Health processing is suspended during the Pull down
period. If the Pull down time period exceeds 75 minutes in
a Frozen cabinet or 30 minutes in a Food cabinet
however, vending will also be disabled in that cabinet for
health reasons. Vending will be allowed again after the
door to that cabinet has been opened and closed.The Pull
down period does not apply to the Ambient cabinets. If at
any time during normal operation after an initial Pull down
period, the temperature in a Frozen cabinet rises above
the set target temperature by 10° F for more than 15
continuous minutes of temperature readings, vending will
be prohibited in that cabinet. If at any time during normal
operation after the initial Power Up Pull down period, the
temperature in a Food cabinet rises above +45° F for
more than 5 continuous minutes of temperature readings,
vending will be prohibited in that cabinet.The cabinet
temperature control processing will remain unaffected by
this vending state. An error message will be recorded
indicating the Health Time-out occurred. Vending will be
allowed again after the door to that cabinet has been
opened and closed.

2.04
components
Defrost Processing
The refrigeration units in the 320 cabinets are defrosted
by the refrigeration control system at regularly scheduled
intervals based on the Defrost Interval, starting from the
Defrost Time selected in MasterMenu™ . A defrost cycle
will begin with the compressor and condenser fan turned
off and the defrost heater on.The heater will remain on
until the Defrost Thermal switch indicates that the
temperature of the air around the refrigeration coils has
reached the desired temperature. The compressor will
then be turned on two minutes later. Normal refrigeration
processing then resumes. A Defrost cycle will also occur
75 minutes after the door is closed in a Frozen cabinet or
45 minutes after the door is closed in a Food cabinet. If
the cabinet is a Food cabinet and the compressor has not
yet reached Pull down, the Defrost cycle will be delayed
until it reaches Pull down. Another Defrost Cycle will occur
either 6 or 8 hours later where 6 or 8 is the number of
hours specified in the Defrost Interval field of the Setup
Defrost Menu Item in MasterMenu™ . If a scheduled
defrost is to occur before 4 hours after the Power Up
defrost is complete, it will be delayed until 4 hours after
the Power Up defrost is complete. All subsequent
scheduled defrosts will occur at their normal times.
Manual Forced Defrost
Enter Master Menu, Configuration Menu, Setup Defrost menu item for specific cabinet, Press F2, compressor will turn off
and a defrost cycle will begin following the sequence above.
Normal Temperature Operation:
With temperature set at -15°F, the following three conditions indicate a correctly operating refrigeration unit:
1) Unit should reach that temperature within 1 hour.
2) After reaching that temperature, Compressor On cycle should not exceed 35 minutes.
3) During a defrost cycle, cabinet temperature should not rise above 0°F.

Vend Motors
The vend motors used in the APi 320 machines have been specifically developed to operate with the APi MasterVend™
Control System and are different physically from previous motors. The motors are color coded, but one primary
difference that distinguishes the new motors from previous motors is the presence of an eight sided star at the drive hub
of the motor. This permits the stopping position of the spiral to be customized by the operator to ensure the best possible
delivery of product.The combinations of different colors on the motors and their hubs will help identify its function (see
figure 2.1).
Some of the motors used in the 120 & 320 will be of the fast trac style, with all electronics required to correctly operate
the motor contained inside the gear case or the motor housing and no external control board. Each of the motors used
with the MasterVend™ Control System will have two terminals. The two terminals continue to be used to identify the
shelf and column (selection) to be vended. In a cabinet that contains a Food Driver Board, their are left hand and right
hand motors, this permits odd and even motors to be paired and operate in counter rotating (similar to the current dual
spiral motor) and creates a very flexible means to vend items of many shapes and sizes. This is accomplished by
removing any motors between the two motors required to vend the properly and pairing the odd and even in the motor
pairs menu items.
Cabinet and Shelf Harnesses
The shelf and cabinet harnesses connectors are different than the snack motors, they have been changed to insure a
better connection.This change in addition to using a lower temperature grease in the motors, was made to insure the
motors would operate in colder temperatures.

SHELF WIRING DIAGRAM
Each motor requires two wires to operate correctly. These wires are: shelf common, and selection.
Each selection on a shelf has the same common shelf wire - all shelf harness use the wire #12 as a shelf common.This
corresponds to the selected shelf wire in the cabinet harness. The terminal for the shelf common in the harness is the
smallest of the two terminals.
Selection numbers are assigned from left to right, starting with selection 0. Each selection number corresponds to the
number of the wire for that selection.

Selection System
The selection system used with the MasterVend™ Control System is different from all previous alpha-numeric systems
we have manufactured.The eleven digit selection panel (see figure 2.2) is located on the front control bezel and consists
of the numbers 0 through 9 and the letter C, which is defined as a clear button.The selection system used with the
MasterVend™ Control System is all numeric and uses three digits to identify all the selections. The first digit is used to
determine which cabinet is selected, the second digit determines the shelf selected, and the third digit, the selection on
that shelf. The left or first selection on each shelf is designated as selection 0, and on a ten select shelf the selection
numbers would be increase by one, so that the right hand selection will be selection 9.The numeric keys on the selector
panel can be used to enter numeric data any time it is required during setup or maintenance of the equipment.

MasterMenu™ Keypad
The MasterMenu™ keypad (pictured below) is located on the front of swing out panel directly below the selection
keypad. The MasterMenu™ keypad is only active when the door is open, so even in the event of vandalism to the
control bezel, no access to the control functions is permitted.The MasterMenu™ keypad consists of seven function
buttons, a *key, four coin payout buttons and the eight keys used to operate the MasterMenu™ functions. The entire
keypad becomes active once the machine door is opened.
Function Buttons
The seven function keys (F1-F7) are assigned to specific pre-determined menu headings, primarily for route service
personnel. See page 4.02 for specific menu heading for each of the function keys.
Pressing the *key before one of the function keys ¡through ¶are assigned to the second level of menu headings.
Coin Payout Buttons
The four coin payout buttons are used to pay coins out of an L+ or a standard US (dummy mech).The four coin payout
buttons are , , and .The four coin payout buttons may also be used to enter pricing
information while assigning prices. For example, to enter a price of $.65, pressing the key twice, the key
once and the key once, would result in .65 appearing on the display. See the price setting section for additional
information.
The skey is used for exiting the current menu without making any changes prior to commitment. Note: Closing the
main cabinet door will have the same effect as if the user pressed the skey and causes the machine to exit the
MasterMenu™ System and return to Operational Mode.
The ekey provides a dual purpose operation. It provides the a mechanism for entering a menu. It also provides a
means to commit insertions/modifications/deletions made in a menu item.
The +and -keys are used for incrementing and decrementing the available choices in a menu.
Note: Anywhere in this manual that the +or -keys are defined to sequence through numeric data, the front
panel may be used as an alternate input source.
The <and >keys have a dual purpose operation.They provide a means to select the menu heading immediately to
the left or right of the current menu heading.When inserting data within a menu , these keys also provide a means to
move the cursor from its current position to the position directly to its left or right.
The ykey is used to delete the character on the current cursor position, shifting all subsequent characters to the right
of that position left by one.
The fkey provides a mechanism to insert a character to the left of the current cursor position, shifting all characters
to the right of that position (including the current character) right by one.
Note: Depressing a function key will not cause you to enter the MasterMenu™ System.

Control System and Boards
The MasterVend™ Control System consists of up to three different boards, depending on the configuration. All Model
120 and all Control modules consist of the LogicCenter board (LCB) and the display board. All 320 machines also
contain a Food Driver Board (FDB).
LogiCenter Board (LCB)
The LCB interfaces with the FDB (when used), display board, selector panel, MasterMenu keypad, coin mechs, bill
validators and all other peripherals. The LCB also stores all the programing and Mis information.In addition the LCB
supplies power to the FDB. (ESD sensitive)
Food Driver Board (FDB)
This board contains all the temperature monitoring functions for cabinet that it is contained in, and communicates with
the LCB via a 6 wire computer level interconnect harness. The FDB has three LEDs on it and the status of the FDB can
be determined by observing these LEDs. The three LEDs will give you the status of the communications between the
FDB and LCB, if the board is currently telling the refrigeration unit to run, and if the board is currently telling the machine
to go through a defrost cycle. (ESD sensitive)
The Food Driver Board is located on the front face of the Relay Box for the compressor assembly. This board controls the
function of all the refrigeration components along with providing the circuits for the vend motors and the baffle delivery
door. There are also two jumpers for default settings of this board.These jumpers are a set of three pins which will have
only two pins connected at any one time. The connection between the two pins is made by a small black cap, which
slides over the pins in use. The black caps are identical, and should not be removed from the board for any reason.The
two jumpers are the Cabinet selection jumper and the temperature control jumper.
Cabinet Selection Jumper
The position of this jumper identifies which cabinet is named CAB1 (Cabinet 1), or CAB2 (Cabinet 2).These are
abbreviated on the FDB board cover decal (pictured below) as C1 and C2 Cabinet 1 will contain the selections 110
through 157, and Cabinet 2 will contain the selections 210 through 257.All machines are shipped with this jumper
installed on CAB1.This jumper should be changed only if you are connecting a second cabinet to a 310 Control
Module or a 120 Snack.
Temperature Control Jumper
The second jumper on the board controls the default setting for the temperature in the event the FDB looses
communication with the LCB. This will hold the cabinet temperature at the setting indicated by the jumper. A jumper
set at “R”will hold the temperature at 36°F (2°C), and a jumper set at “F” will hold the temperature at -15°F (-26°C). If
you change the temperature in the SET TEMPS menu item, you must also change the position of the jumper to the
corresponding position.The position of this jumper can be verified through the hole in the board cover.
The Front Panel Display
The display is capable of displaying 20 alpha-numeric characters. The supported character set includes:
• Upper case alphabetic characters “A” through “Z”
• Numeric characters “0” through “9”
• Special characters: (, ), [, ], ., ‘, -, =, $, /, \, *, ^, +, , ,”, ?, _.
