7.12 16 Amp Filter
A 16 Amp filter, mounted on the rear panel, prevents spurious voltages reaching the
power supply, I/O board, controller boards and other sensitive components within
the machine. It also prevents spurious voltages generated by the machine from
reaching the mains supply.
7.13 Coin Mechanism Transformer
The coin mechanism transformer converts 230v AC to 24v AC for Executive
protocol type coin mechanisms. The 24v AC supply is protected by an in-line 4 amp,
glass fuse, which is located in the door assembly above the coin mechanism.
7.14 Coin and Card/Key Systems
The Genesis may be equipped with coin or card/key validation systems using either
protocol ‘A’ or alternatively 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.
7.15 Change Giver
1. The Change Giver communicates with the vending machine controller
through a serial communication interface. It will validate a coin and if
accepted, send a signal to the vending machine controller indicating the
total amount of money which has been tendered since the last vend.
2. Once sufficient credit has been accumulated a vend will be permitted.
Where possible the change giver will return the appropriate amount of
change to the customer.
7.16 Coin Blocker
For Genesis machines fitted with a change-giver, a logic ‘low’ level from the vending
machine controller will disable any coin acceptance.
7.17 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.
