3.0 VENDOR SYSTEMS AND COMPONENTS
3.1 SENSIT 3 SYSTEM THEORY OF OPERATION
1. The Sensit 3 system is comprised of three elements;
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. The primary sensor, the
secondary sensor and the control board controls the
performance of the vending operation.
2. When a selection is made, the vend motor will begin to
run. After several seconds, if no product falls in the
hopper, 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 and removes the
credit.
4. When the merchandiser is serviced with the door open,
the protective lens on the sensors can become fogged
up, particularly in humid locations. In these cases, the
merchandiser 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
merchandiser, DEX, and the mode switch used to enter
service mode. The control board is located in the upper left
hand corner of the open cabinet door, behind an access
door.
3.2.1 Upgrading Software
The software can be upgraded by using the SD
chip. Note that all settings such as pricing and motor
configuration will be saved. Refer to Section 8.1.
3.2.2 Mode Switch
Pressing the mode switch (Refer to Figure 3.1)
allows the user to get in to the computer’s service mode to
change settings, access vend data, and check error codes
for troubleshooting. Data is displayed on the front display
panel, and changes entered using the keypad. Pressing
the switch again or closing the door will return the
merchandiser to vend mode.
3.2.3 DEX Jack
The DEX jack (Refer to Figure 3.1) is provided for
use with external features, such as Speech (Refer to
Section 6.9.5). Data collection with third party devices can
also be made.

3.3 VEND SENSOR
3.3.1 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.
3.3.2 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 sends light to and receives
light from the secondary sensor (both sensors operate the
same way in this regard). When servicing the secorndary
board, be mindful of the emitters and detectors, which can
be damaged by rough handling.
