Introduction
The main characteristic of the Aeterna Change-Giver is the possibility of giving back any excess
credit present after the sale. This function comes from a system of coin selection and accumulation
inside the tube group. The Change-Giver is prepared to support the following protocols: BDV, MDB,
Executive and Parallel. The Aeterna Coin Mechanism is made almost entirely of plastic materials and
it can be divided into four main units:
•
Coin Mechanism Base board;
•
Validator/Separator group;
•
Tube group;
•
Ejection
group.
In the
Base Board
of the Coin Mechanism take place the main microprocessor, the eeprom containing
the programming data and the reference model for the coins, the connectors for connecting to the
peripherals of the payment system, the PC programming interface, the peripherals for data recording
and for the Coin Validator.
The
Validator/Separator group
can accept up to 60 types of coins or tokens. The coins which result
to be valid are addressed to a conveyor with different channels, each of them is addressed to the
tubes or the cash. On the front panel of the Validator/Separator group is placed the programming
keypad
and the
display
of the Coin Mechanism.
The
Tube group
is the "store" of the Coin Mechanism where the coins which are used to deliver the
change are accumulated.
The
Ejection group
consists of 3 motors and 5 cams of different shape; each of them pushes the coin
towards the return channel during the delivery phase.
WARNING: to use your Aeterna Change-Giver Coin Mechanism correctly, it is essential to
follow the instructions given in this manual. We strongly recommend that you read every
part carefully before starting up the System, so as to prevent possible damage due to im-
proper use.
