AC DISTRIBUTION BOX
The AC Distribution Box is located inside the service area, mounted to the back wall above the
Power Supply. It is where the 120VAC or 230VAC input voltage is sent to the Refrigeration
Unit & Condenser Fan, Evaporator Fan, and Power Supply which converts the AC voltage to
the main operating voltages of the Vender (24VDC). Those voltages are sent to the VMC via
the P1 (4 pin) connector. It contains an independent Cabinet Environmental Control for
improved troubleshooting and to distribute AC power to the Compressor,
Evaporator/Condenser Fans, and DC power to the LED Lighting and Encapsulated Temperature
Sensor. The Compressor, two vertical side LED Light Strips, and the Encapsulated
Temperature Sensor are not powered up when the Machine turns on. The Compressor turns
on 2 minutes after the Machine is powered on. The two side LED Light Strips, Evaporator Fan,
and Encapsulated Temperature Sensor turn on when the Environmental Cabinet Control
Board begins to communicate to the VMC (Vending Machine Controller). Two 3 Amp circuit breakers protect
the 24VDC supply. One is for the Cabinet electronics and the other is for the Door electronics. This AC
Distribution Box is common across all New Electronics Platform BevMax Refresh Domestic, Export, Classic
(BevMax 4), and Media (BevMax 6) models.
VENDING MACHINE CONTROLLER & 5 CABINET PERIPHERAL CONTROLLERS
VMC
(Vending Machine Controller) is the heart of the Vender and is located on the
Service Door just above the Port Assembly behind the Keypad. It is USB
flash programmable and updates all Cabinet Peripheral Control Boards
which control all aspects of the Vender (includes AC Distribution Box
Environmental Board, X Motor Board, Y Motor Board, Port Board, & Cup
Motor Board). The VMC includes 7 Diagnostics lights providing
information on operational status and where to focus problem solving
efforts. All voltage in the VMC and Cabinet Peripheral Control Boards is
24VDC or 5VDC.
Environmental Board
– controls the Refrigeration Unit & Condenser Fan, Evaporator
Fan, LED Lighting, Encapsulated Temp Sensor, and 24VDC & 5VDC power distribution.
X Motor Board
– controls X Motor movement and senses the X Home Switch.
Y Motor Board
– controls Y Motor movement and senses the Y Home Switch signal.
Note: The X & Y Motor Boards are the same Board but with their own specific software.
Port Board
– controls the Port Vend Sensor, Port Open & Close Sensors, & the Port
Motor.
