This chapter describes how the coin validator works:
•
Coin acceptance and coin channels
•
Memory blocks
•
Accepted coin sensor and sorting control
•
Coin pulses and signal lines
•
Coin inhibition/activation of narrow coin channels
•
Sorting accepted coins (option)
•
Teach mode (option)
•
Manipulation detection (option)
5.1
Coin acceptance and coin channels
For coin acceptance the coin validator has 32 "memory slots" 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.
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 to one another so that false coins with similar measured values
are rejected, if the normal channel is inhibited
(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 signal
line and pulse number or sorting information for a 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.
Eight coin channels are intended to be used for the teach mode. In these teach channels new
tokens/coin types can be taught also without configuration and service tools, directly on the coin
validator using the switch blocks. I.e. a new coin or token is assigned to a channel
