MSX models are fitted with a graphic digital display, 128x128. It allows for simple management of the programs and offers an effective visual help for the user.

If there are no active errors, when the machine is switched on, the machine management software will analyse the operation of the components and will auto configure the machine; recognising the motors and assigning a two digit number to each motor present. The software recognises the tray number (rows) which makes up the first part of the number and then gives the second digit the motor number (columns)

On the example below the software has identified that it is a 10 compartment machine with two shelves and 12 motors installed. Shelf number 1 has ten motors while Shelf number 2 has two motors assigned, numbers 21 and 23 respectively.

 

 

The symbol ‘0’ indicates that an active motor has been detected the symbol ‘- ‘indicates

no motor is present or detected.

All active motors are then stored in the memory and individual prices can be assigned to each motor or spiral .The auto configuration is run each time the machine is switched on or off, the door opened or any programming has taken place

 

The left hand site shows the operating temperature that is continually monitored in real time.

The right hand part of the display shows the status of the machine

In order to enter into the programming mode, you will need to open the inside door which covers the coin mechanism and press the Mode switch.

The front display will the show “Enter Password”, if a password has not been set just press “Enter” to go into the main menu. Otherwise enter your 5 digit password

                                              

The machine will enter the programming mode and the main programming menu will come on the display.

You can scroll down the sub menus

Using the “A” or” C” keys and using the “Enter” key to get into any sub menu.

 

Press the “Cancel” key to step out of a menu

 

Go to “Return to Service” and press “Enter” 

 

 

Once a sub menu has been selected

Press the Enter key to get into it

                      

 

The microprocessor board users FLASH MEMORY TECHNOLOGY which can be updated at any time without EPROM changes, an external PC is required if a software update is required.

Switch off the machine from the mains electrical supply, run a serial RS232lead from the PC to the serial connector on the microprocessor board. Set the slide switch on the microprocessor board to “prgm”. and switch on vending machine Use the file transfer software to update the new software.

This procedure must be repeated on the I/O board located on the RHS of the refrigeration unit.

During programming with a PC, the programming slide switch must be on the left.     

 

During the programming with a PC, the programming slide switch must be on left.

 

 

This circuit board is located on the LHS refrigeration unit. To access it disconnect the vending machine from the electrical supply and remove the front panel that covers the fridge unit. From here access can be had to the serial connector and the programming switch.

Programming switch must be positions on PGM-EN during the programming.

The I/O circuit board communicates and drives the peripheral units within the vending machine, including the refrigerator and motor drives, it also communicates with the microprocessor board through CAN-bus.

The bus is a separated CAN-IN and CAN-OUT. The CAN-IN will receive the commands from the card CPU EN0453, the CAN-OUT will communicate with other cards provided on the same bus.

It is necessary to have the file transfer software installed on a PC to communicate with I/O board and the Microprocessor board
