VENDOR SYSTEM AND COMPONENTS
SENSIT 3 OPERATION
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.
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.”
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.
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.
CONTROL BOARD
The control board controls and monitors the vendor, DEX, and
MDB systems. The control board is located in the upper right
hand corner of the open vendor, behind an access door.
Upgrading Software
The software 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
UPGRADING FIRMWARE
on page 33.
Mode Switch
Pressing the mode button (Refer to
Figure 3.1
above) 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.
DEX Jack
The DEX jack (Refer to
Figure 3.1
above) is provided for use
with external features, such as Speech (Refer to
OPTIONS
on
page 26). 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.
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 temperature sensor to the control
board. When servicing the primary board, be mindful of the
emitters and detectors These can be damaged by rough
handling.
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.
DOOR
Validator & Debit Card Reader Locations
There are two locations that will accept bill validators and/or
debit card readers. The lower position meets the guidelines of
