How The Discriminator Works - Azkoyen COMBO-T Technical Information

5.6.1 How the Discriminator works

The basis of how the Discriminator works is by measuring the diameter of the coins using three
optic sensors.
How to achieve high efficiency in the payment
The advantage of the Discriminator against other types of hopper is the possibility of using two
types of coin in the hopper.
In systems where the available space for hoppers is limited, the use of the Discriminator favours
an optimisation if this space.
However, the existence of two types of coins inside the hopper makes necessary to have proper
control of the cash to achieve high efficiency in the payment.
Here several considerations to take in account, both in the management of cash by the master
and also in the service tasks of the machine. The principles are:
•
Balance of coins
The initial fill of the Discriminator must have a balance of suitable coins of both types.
The currency of each type of coin value must be equal. That is, if for example, coins of
50 c and € 1 are stored, the number of coins of the first value will be the double that of
the second value, or put another way, the ratio of the number of coins should be 2:1.
•
Proportion of the values used
For greater efficiency of the Discriminator and of the system, we recommend the
proportion of 1:2 for the value of the two coins used, e.g. 10c and 20c or 5c and 10c.
•
Register of the transactions and calculus of the available cash
The master must register and control at all times the accounting of the coins inserted
and paid out by the application. In this way, you can manage the dynamic processes of
refunding coins, ensuring the availability of change and maintain a high speed in the
execution of the payment.
•
Dynamic control of the payment orders.
IMPORTANT:
For the serial Discriminator to work properly, the coins
that are used in the same hopper must have a difference
in diameter of at least 1 millimetre.
