1.0 INTRODUCTION
Congratulations on the purchase of your new AMS
Sensit 3 vendor. All Sensit 3 models, including Snack,
Visi-Combo, Bottle and Food Combo, Visi-Diner and
Milk, are versatile, high-capacity vending machines.
AMS machines are designed, tested, and built to
provide years of reliable, low-maintenance service in
an indoor environment. A fully insulated cabinet, DEX
data capability, and flexible product configuration are
just some of the many features built into every AMS
merchandiser.
1.1 SENSIT 3 SYSTEM
Your vendor is equipped with the Sensit 3 control
system. The Sensit 3 system is a patented vend-
sensing system that detects when products fall into
the delivery bin. Basically, a plane of infra-red light is
created across the top of the delivery bin, and the
Sensit 3 system can detect when the light has been
blocked by a falling product. Using this technology,
the vendor “knows” when your customer gets the
product. The Sensit 3 system has several important
benefits:
Guaranteed Delivery
If, during the vend, the product hangs up or an
opening was missed in loading, the helix can rotate
several additional partial revolutions to attempt to
deliver the product. No more hitting or shaking the
vendor to get products that did not fall!
Instant Refund
If the customer does not receive a product, he can
receive a full refund by pressing the coin return, or he
can select another product. No more refund requests!
Adjustable Helix Motion
With the Sensit 3 system, the helix can stop as soon
as the product falls, or when the helix returns to the
home position. See section 6.8 for more information.
Additional Benefits:
1. Opening the delivery bin door will not affect the
Sensit 3 system. The sensors are located above
the delivery bin and will not be blocked by the bin
door. Product that falls while the door is open will
still pass through the beam.
2. Shining a light at a sensor will not allow vandals to
receive free product. Any tampering which
changes the precise amount of light normally
received will be treated as a successful vend,
resulting in the vandal losing his money.
3. Disabling or blocking the sensor will not allow
vandals to receive free product. The Sensit 3
system can over-ride blocked or malfunctioning
sensors and still vend.
4. Opening the door of a cold vendor will cause some
condensation to form inside. The Sensit 3 system
will not allow vending until this fogging clears,
normally within a few minutes of closing the door.
1.2 HEALTH AND SAFETY
H&S Specifications
AMS vendors intended for vending perishable
products (VISI-DINER, BOTTLE and FOOD COMBO,
and MILK) meet the National Automatic
Merchandising Association (NAMA) requirements for
refrigerated food vending machines. As of this writing,
the NAMA specifications for perishable food product
vendors require that the temperature in the vendor
must cool to 41°F within30 minutes of closing the door
or a HS2 error will be generated and the vendor will
not allow sales of protected items. (Note that Delayed
Sales has no effect on this 30 minute cool-down
period). This is to allow a recovery period following
loading: however, all products should be chilled prior
to loading. After the 30 minute cool-down requirement
has been met, if the temperature in the vendor
exceeds 41°F for more than 15 minutes a HS1 error
will be generated and the vendor will not allow sales
of protected items. Selections that are ‘exempt’ from
Health & Safety protection will still be available. See
section 6.6
H&S Software
To meet these requirements, AMS refrigerated food
vendors with control software P/N3427 have a built-in
Health & Safety (H&S) function. The H&S function is
activated automatically in food vendors when the
setpoint temperature is set to 41°F or below. Unless
otherwise specified by regulatory agencies, AMS
recommends setting the temperature to 40°F when
vending perishable food products. See section 8.11 to
test.
H&S Protection
In the event the temperature exceeds the NAMA
specifications following the recovery period or during
normal operation, an error will be generated and the
vendor will not allow sales. This protects the
consumer from purchasing spoiled food. H&S error
codes are detailed in Section 7.3.
Mixing Potentially Hazardous Food
From the NAMA Construction Standard:
700.1B In single compartment machines vending
both potentially hazardous and non-potentially
hazardous food, areas not provided with an automatic
shutoff control shall be clearly marked with labels,
lights or other means that will alert the route person
not to stock potentially hazardous food in those areas.

L0118G
1-2
Sensit 3 Food vendors can be configured for Health &
Safety protection by selection. All vendors shipped
from the factory with FOOD firmware installed will be
configured fir Health & Safety protection of all
selections.
If any selections are exempted, it is the operator’s
responsibility to mark those unprotected selections
with the included yellow labels (or other means), and
to instruct route persons on loading restrictions.
FAILURE TO DO SO COULD RESULT IN AN
UNACCEPTABLE HEALTH RISK TO THE
CUSTOMER.
1.3 ENERGY STAR SYSTEM
These Models have been specifically designed to
consume less energy while maintaining your products
at the desired delivery temperature. They differ from
the VCB/VCF Models in that they use different
refrigeration components and front window heating
systems.
The EPA test requirements are very detailed and
specific, and as a result machines only meet these
exacting specifications when they are configured for
maximum capacities of 12oz. cans and operated at
colder than normal temperature settings. Please
contact AMS for further information.
1.4 MODEL IDENTIFICATION
When requesting service, replacement parts or
technical assistance, please copy the information
found on the vendor Serial Plate (Refer to Figure 1.1).
It is attached inside the door near the upper right
corner of the window and is visible from the outside.
The information contained on this plate is necessary
to determine what parts, kits, or maintenance should
be applied to your specific model.

Figure 1.4 Example Configuration
The above drawing shows a typical configuration
used in an AMS 35 model vendor.
The top tray in the above example contains four
columns, formed by the placement of dividers, with
motors and large diameter helices in place. Note that
as the 39” vendor is wider, its tray can hold 5 large
diameter helices.
The pitch of the helices (the number of slots for
loading product) is given by the number. The size of
the square indicates the size of the helix (small or
large).
All of the top tray helices shown above are of large
diameter, and are of 10, 12 and 15 pitch. The
configuration on this tray can hold 10+12+15+15 = 52
products.
All trays can be configured in this or another
configuration, depending on the products being
vended.
Products which fit in the 10 pitch helix may be too
large to fit in the 15 pitch helix. The product must be
freely pushed out of the column by the helix to fall into
the hopper.
The fourth tray down as shown in the above example
contains eight columns with small diameter helices.
The pitch is 18 for all columns, so the configuration on
this tray can hold 18 x 8 = 144 products. Note that as
the 39” vendor is wider, its tray can hold 10 small
diameter helices.
A working configuration is one column with a given
helix (or two columns coupled,) to vend a given
product. A record of working product configurations,
as shown in the example diagram, will greatly speed
up new set-ups and duplicate vendors.
With Sensit 3, extra wide products can be vended by
‘coupling’ two motors.
1. Form a column between dividers, wide
enough for the product. When viewed from
the front of the tray, install a clockwise (CW)
motor and helix on the right side of the
column, and a counter-clockwise (CCW)
motor and helix on the left side of the
column. Note that all normal or standard
motors and helices turn CCW to vend
product. The motors can be any distance
apart. The helices must be of the same pitch.
2. Using the configuration menu, couple the
two motors together. See Section 6.8.
3. Install the product into the two helices.
Change the selection and price on the tray.
When this product is selected, the two helices will turn
at the same rate to vend the product.
The bottom tray shown in the above example contains
four columns with small diameter, coupled helices.
The pitch is 7 for all columns, so the configuration on
this tray can hold 7 x 4 = 28 products. Again, the 39”
vendor is wider, and its tray can hold 5 coupled sets.

that service may be conducted, or all of the possible
safety hazards that may result from service. Therefore
at all times we urge you to beware of hazards such as
electrical shock, mechanical entrapment, and tipping
a vendor during movement.
Automated Merchandising Systems strongly
recommends a commitment to safety on the part of all
servicing personnel or organizations. Only personnel
properly trained in vendor servicing should attempt
any service to the internal components of the vendor.
Automated Merchandising Systems has no control
over the vendor once it leaves our factory.
Maintaining the vendor in a safe condition is the
sole responsibility of the owner.
If you have questions concerning safety or service, or
would like more information, please contact the
Automated Merchandising Systems Service
Department at 304-725-6921 or e-mail
[email protected].
2.2 SAFETY PRECAUTIONS
Below are listed safety precautions and safe practices
to follow to avoid injury from selected hazards. This
list cannot possibly cover all hazards, therefore
please remember to
++ THINK SAFETY FIRST! ++
High Voltage Contact
Each vendor is designed to operate on a specific
voltage, either single phase 120VAC 60Hz or 220-
240VAC 50-60Hz, depending on the country. The
voltage is specified on the serial plate (Refer to
Section 1.3 Model Identification). High voltage areas
include the electrical panel, the refrigeration unit and
fans, and the fluorescent lamp. It is important to
understand that contact with the high voltage wiring
can result in injury or death.
1. Always test the outlet for proper voltage,
polarity and grounding before plugging in the
vendor.
2. Always disconnect power to the vendor
before servicing. Allow only fully trained
service technicians to service the vendor.
3. Always keep electrical connections dry. Do
not place the vendor in or near standing
water.
4. Never use a worn or damaged power cord.
Grounding
Some electrical components have a green or
green/yellow ground wire attached to a grounding
point in the vendor. If it becomes necessary to
remove a ground wire during service, note how the
wire is attached, including the locations of any
washers. After servicing, make sure that the wires
and washers are replaced exactly as they were. Note
that the vendor may appear to work normally without
the ground wires, but there will be a potential shock
hazard from ungrounded components.
1. Always test the outlet for proper grounding
before plugging in the vendor.
2. Always reconnect ground wires after
servicing.
3. Test the ground fault circuit interrupter
(GFCI) periodically to insure proper
operation. See section 8.13
Fan Contact
Some vendors are equipped with fans which can start
automatically. These fans are guarded to prevent
accidental contact. However, removal of guards or
other components can leave fan blades exposed and
create a physical hazard.
1. Always disconnect power to the vendor
before servicing.
2. Always wear hand and eye protection when
servicing the vendor.
3. Always keep hands, hair, loose clothing and
tools away from fan blades.
4. Never insert hands or tools into concealed
areas.
5. Always replace protective covers after
service.

L0118G
2-2
Helix Motion and Jamming
Energized vend motors can turn a helix with
considerable torque, creating a possible entrapment
hazard. Also, turning helices may eject tools or other
objects left on trays. A helix that is jammed or caught
can store energy as it binds, which can cause it to
twist or spring outward suddenly even if power is
disconnected. Use gloves and caution when freeing a
jammed helix.
1. Always disconnect power to the vendor or
control board before servicing the vend
motors.
2. Always check for proper fit when loading
products in helices to avoid jamming.
3. Always restrain the helix before freeing a
jammed or caught helix.
4. Always wear hand and eye protection when
servicing the vendor.
5. Always keep hands, hair, loose clothing and
tools away from moving parts.
Refrigerant Release
The refrigeration system is pressurized and sealed at
the factory. Puncturing or cutting any component in
the system will cause refrigerant gas and liquid to be
propelled out of the system, creating an immediate
physical hazard. Use caution to avoid accidentally
opening the refrigerant system.
It should also be noted that releasing refrigerant to the
atmosphere is a federal crime and is punishable by
law. Any service work requiring the system to be
opened must be performed by a licensed technician
using certified recovery equipment. Unauthorized
service to the sealed refrigerant system will void the
warranty.
1. Never puncture or cut any component in the
refrigeration system.
2. Always use licensed service technicians to
service the refrigeration system.
3. Always wear hand and eye protection when
servicing the vendor.
Vendor Tipping
The weight of an empty vendor is over 450 pounds,
and can be more than 600 pounds!. A falling vendor
can cause serious injury or death. Caution should
always be taken to avoid dropping or tipping a vendor.
1. Never rock or tip the vendor. It must be kept
horizontal for safe operation.
2. Never place the vendor in an inclined
position, such as on a ramp or with all the
legs not on the same horizontal surface.
3. Never place the vendor in a moving
environment such as on a ship without
properly securing it in place.
4. Never place the vendor in a location where it
may be struck by a vehicle.
5. Never transport an unsecured vendor, or a
vendor still containing product.
6. Never attempt to lift or move the vendor by
hand. Always use equipment with the proper
load rating. Note that the Specification
weight listed is empty weight.
Other Improper Conditions
Hazardous conditions can be created by improper use
or service of the vendor.
WARNING: Do not use electrical appliances
inside the vendor unless
recommended by AMS.
1. Always reinstall any parts removed during
service to their original locations.
2. Never make unauthorized modifications to
any part of the vendor.
3. Always replace components that are worn,
broken, or otherwise unfit for use.
4. Never use unauthorized parts, or use parts
for anything other than their intended use.

L0118G
3-1
3.0 VENDOR SYSTEMS AND COMPONENTS
3.1 SENSIT 3 OPERATION
1. The Sensit 3 system is comprised of the
primary sensor, the secondary sensor, and
the control logic. The primary and secondary
sensors are attached to opposite ends of the
hopper, and infrared light is passed between
them.
2. When a selection is made, the vend motor
will begin to run. After several seconds, if no
product falls in the hopper (or motor returns
to home position), the motor will be stopped,
the credit will be maintained and the
customer will be directed to “PLEASE MAKE
ANOTHER SELECTION.”
3. When the controller measures a variation in
the light intensity during the vend cycle, it
recognizes that a product has fallen through
the light into the hopper. The controller stops
the vend motor (or returns to home position)
and removes the credit.
4. When the vendor is serviced with the door
open, the protective lens on the sensors can
become fogged up, particularly in hot or
humid locations. In these cases, the vendor
will display “SENSIT BLOCKED – UNABLE
TO VEND” until the fogging has cleared,
usually within a minute after closing the door.
3.2 CONTROL BOARD
The control board controls and monitors the vendor,
DEX, and MDB systems. The control board is located
in the upper left hand corner of the open vendor door,
behind an access door.
Upgrading Firmware
The firmware can be upgraded by using a micro SD
card. The card and card readers are available at
Office supply chains or on the internet. Minimum
capacity of 512Mb is adequate. See Section 8.1.
Mode Switch
Pressing the mode button (Refer to Figure 3.1) allows
the user to get in to the controller’s service mode to
change settings, access vend data, and check error
codes for troubleshooting. Data is displayed on the
front display panel, and entered at the front selection
panel. Pressing the switch again, closing the door, or
waiting approximately 3 minutes will automatically
switch the computer back to vend mode.
Figure 3.1 Control Board Components
DEX Jack
The DEX jack (Refer to Figure 3.1) is provided for use
with external features, such as Speech (Refer to
Section 6.10). Data collection with third party devices
can also be made here. Some telemetry-based
devices (which may include cashless devices) have a
permanent connection here.
3.3 VEND SENSOR
Primary Sensor
The primary sensor is located on the left of the hopper
when viewing the back of the door. The sensor, inside
a protective housing, sends light to and receives light
from the secondary sensor (both sensors operate the
same way in this regard). It contains circuitry to send
a signal to the control board. When a product drops
through the beam, it causes a change which is
interpreted by the control as a successful vend. The
primary sensor board also contains circuitry to
connect to the secondary sensor, and to connect the
machine’s temperature sensor to the control board.
When servicing the primary board, be mindful of the
emitters and detectors as they can be damaged by
rough handling.

L0118G
3-2
Secondary Sensor
The secondary sensor, inside a protective housing, is
located on the right side of the hopper when viewing
the back of the door. The sensor also sends light to
and receives light from the primary sensor. When
servicing the secondary board, be mindful of the
emitters and detectors, which can be damaged by
rough handling.
Product Sensor
The product sensor is optional equipment on Snack
models and standard equipment on the other models.
It consists of a single light emitter mounted near the
bottom of the hopper (right side) and a detector
opposite it on the bottom left side of the hopper. Each
is mounted in a protective housing and together they
are used to prevent vending a product if another is
already lying in the bottom of the hopper - this
prevents dropping a glass bottle onto another glass
bottle.
This feature can be enabled or disabled in the
software Options Menu depending on your
preferences.
3.4 DOOR
Validator & Card Reader Locations
There are two locations that will accept bill validators
and/or card readers. The lower position meets the
guidelines of the1991 Americans with Disabilities Act
(ADA) for access by handicapped persons (Refer to
Section 4.2).
Coin Changer Location
Three screws are installed in the door below the coin
chute. These screws mate to the keyhole slots on the
back of the changer (Refer to Section 4.2).
Coin Box
The coin box is located below the changer and is
used to hold non-payout denominations and overflow
coins when the changer’s payout tubes become full. It
is removed by tilting slightly and lifting out.
Door Switch
The door switch is mounted on the back of the vendor
door. The control uses the door switch to turn off the
refrigeration unit when the door is open, and to switch
from service mode to vend mode when the door is
closed.
Display
The display is located on the front of the door. It
serves as the interface for customers using and
operators programming the machine. In service
mode, it displays the active function and parameter
values. In vend mode it can display the selection
entered, the price of a selected item and the credit
accumulated. When the machine is idle it can display
the time and a customizable scrolling message.
When the asterisk key (*) is pressed, the display
shows other machine details. One of the highlighted
characters listed below will be shown in the lower
right corner of the display.
- = Chiller off due to open door
V = Chiller off due to low voltage
D = Chiller off due to defrost timer
P = Chiller off due to pressure timer
H = (Optional) internal heater energized
% = Chiller can run, subject to temperature,
set-point and EnergySENSIT
The number displayed before the % sign indicates the
% of time the compressor has been running in the
previous 4 hours. This is a moving average, and
changes throughout the day.
If there are multiple reasons for a chiller to not be
running, the display will show the foremost reason
listed (i.e., door open takes precedence over low
voltage).
Keypad
The keypad is located below the display on the front
of the door. A vending selection is made by keying in
the number combination that corresponds to the
location of an item in the machine. The keypad is also
used to enter data in operation and servicing of the
vendor.
Coin Return Button
The coin return button is located next to the coin slot.
Pressing the coin return button will release bent or
irregular coins that are not accepted by the changer. If
the machine fails to vend a selection that has been
made, pressing the coin return will return the full
credit. If the Force Vend option is disabled, it can also
return the full credit before a selection is made. If the
Bill Changer option is enabled, the coin return will
return bills held in escrow or change for bills inserted
and stacked in the bill validator.
Lighting Options
Several lighting options, depending on the model and
size of the vendor, are available. All options are
intended to illuminate the products displayed on the
trays. Options include single fluorescent lamps, and
single or dual LED lamps (with adjustable brightness
control).
3.5 OPTIONAL SNACK REFRIGERATION
(CHILLER) SYSTEM
Temperature Control
The evaporator fan runs continuously to circulate air
within the cabinet. A temperature sensor located near
the evaporator measures the temperature of air
entering the evaporator. When this temperature is
above the temperature setpoint, the compressor and
condenser fan are turned on.

L0118G
3-3
When the temperature falls to 4°F below the
temperature setting, the compressor and condenser
fan are turned off (Refer to Section 6.6).
Refrigeration Controls
1. The refrigeration system is operated through
the control board. The temperature sensor in
the cabinet relays the current temperature to
the control board.
2. If the temperature is above the setting that
has been programmed in by the user, the
control sends a 24VDC signal to the
refrigeration relay. The energized relay
closes to complete the high voltage circuit
that powers the compressor and the
condenser fan.
3. If the compressor should overheat, a thermal
overload removes power to the compressor
until it has cooled.
4. To protect against evaporator freeze-up,
after one hour of continuous running the
compressor will be shut off for 7.5 minutes to
allow for defrosting
5. When the temperature in the cabinet
reaches 4°F cooler than the temperature
setting, the control de-energizes the relay
breaking the circuit powering the
compressor.
6. The control will also shut off the compressor
if the door is opened. This is to prevent the
fan from drawing in outside air which may
freeze up in the evaporator.
7. After the compressor has shut down, the
control will wait until the compressor has
been shut down 3 minutes and if applicable,
the door has been closed 10 seconds before
restarting the compressor. The delay allows
pressure in the system to equalize.
3.6 TRAY RAILS
The rails are located inside the cabinet and are used
to support the trays. The rails are adjustable up and
down in 1” increments (Refer to Section 5.3).
3.7 TRAYS
Refer to section 5, and 10 for optional tray
accessories.
Vend Motors
Two types of motors may be used with this vendor.
The configuration of the machine will be different if all
of one or another is used, or if there is a mix. Sensit 3
(or simply S3) software can be used to best
advantage using motors designed for homing, but it
can be set to control motors without the home switch
feature. Motors may be mixed throughout the
machine, but each tray must have all motors of the
same type.
The vend motors are snapped into mounting holes on
the back of each tray. The motor is driven by 24 VDC
through a harness from the control board (Refer to
Section 4.2 and Section 5.10).
S3 Vend Motors
The S3 vend motors have a plastic case of which the
rear half is blue. S3 coupled motors can replace dual
helix motors. Where a dual helix motor is used,
replace it with a 23007 motor (having a blue and ivory
case for CCW rotation) and a 23007-01 motor (having
a blue and gray case for CW rotation) and reinstall
the helices. Use Tray Setup in Service Mode to
couple the motors in each column together, causing
them to turn at the same rate.
Coupled motors will always be stopped when either
one reaches the home position. If one motor runs
slightly faster, the slower will then be individually
driven to its home position. Depending on motor
configuration, the motors may jog twice to try to
dislodge hanging product.
Note: When not in Service Mode, and with door
open, press # to reset all switched motors to
Home position (Not available for non
switched motors. Refer to Section 6.8).
Motors already at home will not move.
Sensit II Vend Motors
A Sensit 2 (or simply S2) vend motor has a plastic
case which is all ivory in color. A dual helix motor has
a larger gearbox allowing two helices, one for CW and
another for CCW rotation, to be installed. The dual
helix housing only allows helices to be adjacent to
each other.
These motors have no home switches and have
been discontinued and replaced with S3 vend motors.
However, the S3 Control Board can be set to
accommodate these motors - see section 6.8 for
details on changing motor types.
Helices
There are four sizes of helices available,
approximately1 ½, 2 5/8”, 3”, and 4” in diameter.
There are several pitches available in each size, and
is determined by counting the number of product
openings in the helix (Refer to Sections 5.6 through
5.10.

L0118G
3-4
Dividers
The dividers separate product columns on the tray. To
remove the divider, push rearward and lift. To install,
insert the rear tab in the desired slot, push rearward
and then down. Make sure the locking tabs on the
bottom have engaged their respective slots and pull
forward. Bottle tray dividers are held in place with
screws.
Candy Pusher Bar
On snack trays, 2 horizontal slots in the divider allow
for the installation of a candy pusher bar. The candy
pusher bar keeps items pushed to one side of the
column. This is typically used with tall products. The
candy pusher bar is removed by pulling the bar free
from the plastic clips. To reinstall, it is easiest to
squeeze the bar into the clip using pliers (Refer to
Section 5.14).
3.8 ELECTRICAL PANEL
The electrical panel is located in the recess formed by
the right rail mount on the right side of the cabinet,
behind an access panel.
Power Switch
The power switch is located on the lower right rail
mount near the fuse. The power switch is used to
disconnect 24VAC power to the control board.
Note: The power should be shut off when MDB devices
are being connected or disconnected, when the board is
being serviced, or before any wiring harness is
connected to or disconnected from the control board or
sensors.
Fuse Holder
The fuse holder is located on the lower right rail
mount near the refrigeration unit power outlet. It
contains a 3 amp fast-blow fuse to protect the 24 VAC
power supply to the control board. A spare fuse is
stored in the cover. The fuse holder is opened by
pressing in and down on the indicated side of the
cover and pulling out.
Transformers
The transformer reduces the input voltage to 24 volts
AC for the control board. An optional 2nd transformer
supplies power to the window heater.
RFI Filter
The filter removes electrical noise from the power
supplied to the 24VAC transformer to prevent
interference with operation of the control board and
software.
Relay
AMS relays use a 24 VDC signal from the control
board to actuate the relay and supply power to the
refrigeration unit or other accessories.
Ballast
The ballast provides the necessary power to the
optional fluorescent lamp in the door.
Power Distribution Harness
The power distribution harness splits the incoming
power into individual leads for the high voltage
components.
Ground Attachment
The vendor electrical ground is made through the use
of grounding studs or screws at the lower back wall of
the right rail mount. Earth ground and individual
ground wires from the high voltage components are
attached here, and should always be replaced
after service or repair.
3.9 POWERED VENTILATION SYSTEM
(OPTIONAL)
On vendors equipped with a powered ventilation
system, a continuously running fan circulates air
through the vendor and exhausts through the back of
the cabinet.
3.10 1.5” HELIX TRAY (OPTIONAL)
The 1.5” Helix Tray is mounted below the bottom
snack tray. To load the tray with small products such
as gum and mints, grasp the tray and pull forward to
unsnap the catches. After loading, push the tray to the
rear until the catches snap in place.
The motors in the 1.5” Helix Tray operate in the same
way as snack or bottle tray motors (Refer to Section
5.15).

4.0 VENDOR PREPARATION AND INSTALLATION
Setting up a vendor has been divided into three
stages. Step 4.1 confirms power and site suitability.
Step 4.2 includes preparations accomplished in the
shop. Step 4.3 is accomplished on-site, where the
vendor is to be located.
4.1 CONFIRMING POWER AT OUTLET
Checking the Outlet (U.S. and Canada)
AMS recommends using a dedicated outlet which can
supply 15 to 20 amps per vendor.
Using a volt meter set to AC VOLTS, check the
voltage between the positive (smaller) lug entry and
the ground lug entry (or center screw on two-lug
outlets). The reading should be between 110 volts
and 130 volts. Next, check the voltage between the
neutral (larger) lug entry and the ground. The reading
should be 0 volts. If your results vary, contact a
qualified electrician to correct the outlet wiring before
plugging in the vendor. Abnormal voltage, reversed
polarity or improper grounding may cause the
vendor to malfunction or create hazardous
conditions in the vendor, resulting in possible
injury, damage to the vendor, or fire.
The power cord is shipped in the hopper on the inside
of the door. The cord is supplied with a standard
NEMA 3-wire plug. If there are no 3-wire outlets
available for powering the vendor, a grounding
adapter may be used to convert a 2-wire outlet to
accept the 3-wire plug. The adapter must have a
ground tab or wire which must be fastened to the
center screw of the outlet. If the outlet isn’t
grounded, the GFCI will prevent not provide
power to the machine!
NEVER USE AN EXTENSION CORD
WITH THE VENDOR.
Checking the Outlet (Outside the U.S. and
Canada)
Consult a qualified electrician to check the outlet for
proper polarity, voltage, and grounding. Check the
serial plate on the side of the door to confirm the
vendor is rated for the outlet voltage.
Electrical Service Requirement for CE Compliance
The following requirement applies only to models
using ½ HP compressors and displaying the CE mark

4.2 VENDOR PREPARATION
Inspection
Inspect the vendor carefully for shipping damage prior
to signing the carrier’s delivery receipt. Check for
dents on the top or sides of the vendor, bent legs,
broken glass, or other damage on the exterior of the
machine. Check the interior for components that may
have been knocked loose or other damage.
Mounting and Connecting Bill Validators and Card
Readers
The AMS vendor will support any NAMA-approved
Multi-Drop Bus (MDB) bill validator or card reader.
Please read the device manufacturer’s literature
before proceeding.
1. Always disconnect power to the control board
before servicing.
2. On the inside of the main door, locate and open
the access doors on the left side. Locate the
white plastic coin chute which leads from the coin
slot on the front of the door. Above the coin chute
are (2) metal plates, each fastened to a set of (4)
threaded mounting studs which correspond to the
mounting holes in the bill validator. Either set of
mounting studs may be used for a bill validator or
card reader. The lower mounting position will
allow the machine to meet the 1991 ADA side
reach requirements for consumers with
disabilities.
3. Remove the four nuts that retain the steel cover
panel. Remove the steel cover panel, then press
out the plastic cover panel in the escutcheon.
4. Refer to the manufacturer’s literature for
instructions on accessing the mounting holes in
your device. Place the mounting holes over the
threaded studs and reinstall the nuts. Some
devices may require spacers, which are available
from AMS (Part Number 20258).
Mounting and Connecting Coin Changer
The AMS vendor will support any NAMA-approved
Multi-Drop Bus (MDB) Coin Changer. On some export
models, Executive-type Changers are supported as
well. Please read the manufacturer’s literature before
proceeding.
1. Always disconnect power to the control board
before servicing.
2. On the inside of the main door, locate and open
the access doors on the left side. Locate the
white plastic coin chute which leads from the coin
slot on the front of the door. Below the coin chute
are (3) screws which correspond to slots on the
back of the changer. Do not adjust these screws.
3. Install the changer by placing the large round
opening at the bottom of each slot over a screw
head. Be careful to hold the wiring harnesses in
this area out of the way. Once each of the round
openings are over the screw heads, the changer
is lowered to engage the narrow portion of the
slot with the shank of each screw.
4. Tighten the mounting screws (reference
manufacturer’s literature).
5. Adjust the white plastic coin chute as required to
align the chute with the changer.
Connecting the MDB Devices
Note: Always disconnect power to the control
board before servicing.
If your vendor is equipped with LED lighting, the MDB
Harness from the Control Board must connect directly
to the LED connector. If there are dual LED’s to be
connected, connect first to one LED and then connect
the second LED into the free connector of the first. If
the LED’s are not the first items connected to the
Control Board, they will not be dimmable.
Connect the Card Reader (if present), to the LED’s
free connector – or directly to the Control Board if no
LED lighting is present - then the Bill Validator (if
present) and finally the coin changer. Note that the
changer has no continuation connector, so it must
always be the last device connected.
Reconnect power to the control board.
Configuring Motors
The vend motors MUST BE CONFIGURED after any
changes in the arrangement, type, or number of
motors have been made.
1. Press the service mode switch on the control
