This chapter describes how the coin validator works:
•
Coin acceptance and coin channels
•
Single or double block data-management
•
Accepted coin sensor
•
String recognition
•
Control for external sorting device
•
Coin inhibition/activation of narrow coin channels
•
Teach mode
5.1
Coin acceptance and coin channels
For coin acceptance the coin validator has 32 "memory blocks" to which up to 32 different coin
types or tokens can be assigned. These "memory slots" are called coin channels. The acceptance
band of one coin type/token is assigned to each coin channel and the respective coin type/
token is accepted in this channel.
After a reset, coin acceptance is inhibited and must be enabled by the machine.
By default, the v
2
colibri refuses to accept any further coins if the machine had
not addressed it within the last 500ms or if the machine has not yet polled the
last accepted coin.
To enable reliable rejection of false coins, channels with a narrow or even very narrow acceptance
band are frequently set up for a coin type in addition to the normal coin channel. The limit values
of these coin channels are closer together so that counterfeit money with similar measured values
can be rejected if the normal channel is disabled
(cf. Chap. 7.2 Inhibiting coins/activating narrow coin channel ...,
. However, narrow and super‑narrow coin channels also have a lower acceptance rate.
In addition, it is possible to assign coins with different measured values but identical coin values
to different coin channels. In this way the coin validator can accept e.g. old and new coins of
the same denomination.
In addition to the acceptance band of a coin type, further coin information which defines further
processing of the coin after its acceptance is assigned to a coin channel: e.g. the coin value or
sorting information for an external sorting device.
Since in most cases not all coin channels are assigned by customized factory programming
,
further coin types and the desired information can be assigned to these free channels at any
time using the NRI configuration and service tools. Existing configurations can be changed.
The last eight coin channels 25 to 32 (or 9-16 with double block data-management
Single or double block data-management, p. 20)
) are intended for teach mode. In these teach channels,
you can also teach new types of tokens/coins directly via the switch blocks on the coin validator
without needing configuration and service tools; i.e. a new coin or token is assigned to a channel
