1.5. General Operation
The main feature of the Aeterna Change Giver Coin Mechanism is its ability to accumulate coins
inside the tubes and to return to the user any excess credit present after a sale. The operation of
coin accumulation and distribution occurs in three phases: recognition/separation, accumulation and
ejection.
When a coin is inserted in the
Validator/Separator group
, it is analyzed and compared with the
reference parameters present in the model. If the coin
is validated
, it enters the conveyor and then
it is addressed to the tubes or the cash.
The Coin Mechanism uses 2 groups of photocells which are placed in the lower and in the upper part
of each tube to check the level of the coins present at their inside and if necessary to make the
corrections to the coin counters. The coin counters present in the tubes permit to execute the
analysis and the calculation of the change composition.
When inside the tubes the maximum limit of coins is reached, the latters are automatically
addressed to the
cash
. This occurs with the validated coins too, which are not configured inside the
Tube group
.
If the coin
is not valid
it passes directly from the Validator/Separator group to the
Reject Channel.
All the operation phases of the Coin Mechanism and the programmed data concerning each operation
are shown on the
display
, which is placed
on the front of the Validator/Separator group.
The
Ejection group
starts to work when the microprocessor signals the presence of a residual credit
after the sale operations. By means of the data set during programming the type of coin and the
number of pieces to be distributed are defined. The motors powering the cams, which are placed at
the base of each tube, permit to direct the coin to the return channel and then to the coin recovery
tray, which is at user's disposal.
1.5.1. Coin reading
At switching on the Aeterna Coin Mechanism displays: the
"Aeterna" inscription on the upper line and the number of coins
present in each of the 5 tubes into square brackets on the lower
line.
If the tube box results open, the display is this one:
When a coin is inserted in the Coin Mechanism on the upper line
of the display is shown the "Aeterna" inscription
while on the
lower line are displayed the
currency
(ex. EUR) and the coin
value
(ex. 0.10), the storage
channel
, which is occupied by the
coin just passed in the model (ex. C04) and the coin
destination
(ex. tube 2 =
2).
