General Information
The G-10.4000/5 is a microprocessor-controlled validator, which includes a serial interface for the data
transfer to the control unit.
Measurements
When a coin passes the measurement area within the validator, the coils measure the coin characteristics
of alloy, thickness, diameter and embossing. The measured analog values are recorded and processed
to 6 digital values.
For coin validation 6 parameters are available:
NFP = Phase shift measurement with low frequency
GRO = Diameter measurement with upper sensor
GRU = Diameter measurement with lower sensor
NFA = Amplitude measurement with low frequency
RCH = Calculated value
HFP = Phase shift measurement with high frequency
Coin channels
The inserted coin generates one value for each of the 6 parameters. The validator checks, whether this
value lie within its programmed limits, i.e. within the coin channel.
Within each channel the limit values for one coin denomination can be set. The 12 coin channels of the
G-10.4000/5 enables the coin acceptance of a maximum of 12 different coin denominations. This means
coins, whose characteristics correspond. Thus this also refers to tokens. Based on this there are two
coin channels programmed instead of only one in case of the acceptance of an old and new coin
denomination (for instance 0.10 £ old and 0.10 £ new).
Alternatively it is possible to programme a channel with 'normal bandwidth' and with 'narrow bandwidth'
for the same coin denomination.
To each coin channel one coin denomination can be assigned.
The G-10.4000/5 can validate up to a maximum of 8 different coin values. The coin channels 9 to 12
are linked up with the coin channels 1 to 8 and thus a coin value is assiged to these coin channels.
