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.
