A FRESH APPOACH TO VENDING
7.11 Mains (Voltage) Filter
A mains filter, mounted on the rear panel, prevents spurious voltages generated by the
machine from reaching the mains supply. .
7.12 Coin Mechanism Transformer (Optional Extra)
The coin mechanism transformer converts 230v AC to 24v AC for Executive protocol type
coin mechanisms and cashless systems.
7.13 Coin and Card/Key Systems
The VOCE may be equipped with coin or card/key validation systems using either protocol
‘A’ or an MDB system. The coin or card/key system informs the vending machine
controller of the amount of credit which has been deposited into the vending machine.
7.14 Coin Mechanism
1. The coin mechanism which validates the coins, communicates with the vending
machine controller through a serial communication interface.
2. Once sufficient credit has been accumulated a vend will be permitted. Where
possible the coin mechanism will return the appropriate amount of change to the
customer.
7.15 Card/Key System
1. The card system fitted to the machine communicates with the vending machine
controller using the same principle as the change giver.
2. The card system informs the vending machine controller of the amount of credit
on the customer's card. If there is sufficient credit for the selected drink, the
vending machine controller permits a vend and informs the card system of the
amount of credit to be taken from the card. The new balance will then be re-
written onto the customer's card.
N.B. For full information and programming instructions for all of these systems, please
refer to the user manual supplied with the validation system.
