VENDOR SYSTEMS AND COMPONENTS
SENSIT 3 SYSTEM 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 the cabinet at 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 and the
credit will be returned to the Vagabond system.
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 it to home position) and sends a successful
vend message to the Vagabond system.
CONTROL BOARD
The control board controls and monitors the vendor, DEX, and
MDB systems. The control board is located in the control box
attached to the rear of the vend hopper -See Figure 3.2 on the
next page.
Upgrading AMS 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
FIRMWARE UPDATES
on page 33.)
Mode Switch
Pressing the mode button (see
Figure 3.1
on the right), 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 Display and entered
via the keypad (See
Figure 3.2
). Pressing the switch again,
closing the door, or waiting approximately 3 minutes will
automatically switch the controller back to vend mode.
DEX Jack
The DEX jack (see
Figure 3.1
on the right), is provided for
external sales data collection. Since your Touchless Sales
information is all available online through the Vagabond App,
you shouldn’t need to use this feature.
Should you desire to retrieve DEX data, however, it is simple to
do using a Micro-SD card. Please refer to
RECORDING DEX
DATA ON SD CARD
on Page 34 for details.
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.
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.
