BEVMAX REFRESH SEQUENCE OF OPERATION
Machine is sitting powered up and in an idle state ( waiting on a consumer)
A credit is established by the consumer via coins, bill, or cashless device
As the VMC recognizes the currency, it will instruct the display to show that amount and wait for
activity on the keypad
When a selection is made by the consumer, the VMC will check the amount of credit available
against the selection requested to decide if it can vend that product
If the VMC determines the credit is adequate for that selection, it will then instruct the display to
show the word VEND
The VMC will then communicate with the Y and X Motor Control Boards via the RS45 to get its
status, i.e., is its home switch closed, and it will communicate with the Cup Control Board to
ensure the picker home switch is closed. If the Picker is extended it will not turn on the X or Y
motors
It will also communicate to the port to determine if the port is opened or closed
Once the VMC is certain that the all home switches are closed, the VMC will instruct the X and Y
motor controllers to run the motors to the position that corresponds with the selection
requested.
Once the cup arrives at the selection the cup stops and both X and Y controllers report to the
VMC that they have arrived at the location, and their home switches are open. X and Y controllers
will wait for the next command
The VMC communicates with the Cup controller and instructs it to activate (turn on) its cup
sensor
The VMC will instruct the Cup controller to run its motor
Once the cup motor runs, the cup controller will communicate to the VMC that it ran it’s motor
and that it does or doesn’t have product in the cup
If there is product in the cup at this time
The VMC will then instruct the X and Y boards to run their motors to take the cup to the Hook
Swipe position
If the cup reports back that product is present, the VMC instructs the X and Y boards to swipe
After the swipe motion the X motor will back off 1” and hold in place
After all three boards report to the VMC that they have completed their tasks, the VMC will
instruct the X and Y boards to return the Cup to the home position
Once the Cup arrives home, the X and Y boards will report back to the VMC that the cup is home
The VMC will tell the Port board to open the port and ask if it has product present
The Port board will open the port
The consumer removes the product, the VMC instructs the Port board to close the port
The VMC will instruct the display to show THANK YOU
The Vender will go back to idle and wait for the next vend.
