In comparison to the former 3-tube changers, the 4-tube changers do not
onlyhaveanadditionaltube,butalsolengthenedtubes,morecoinchannels
and further functions. The coin validator offers a reliable sensing system
and rejection of false coins with the proved and well known coin validator
G-40.4000.
Duetothemodulardesign,youcanindividuallycombineyourchangerwith
accessories (see chap. 3 "Options"). Configuration is carried out via a PC,
Palm handheld or via the setting module.
This manual only considers the setting module for configuring the coin

Sorting the coins
A coin inserted into the machine first enters the electronic coin validator,
where coin characteristics such as alloy, diameter, weight and embossing
are checked by means of probes and light barriers. If the measured values
do not lie within the programmed limit values the recognized false coin will
berejectedviathecoinreturn.Otherwise,theacceptancegateopenstothe
sortingsystem. Thecoin validatornow checksifthecoinis tobe sortedinto
one of the four tubes. If the coin is not programmed as tube coin (see label
of the coin validator) or when the light barrier of the appropriate tube
indicates a full tube, the coin falls into the cash-box.
Payout set with interchangeable tubes
The payout set consists of the payout module and 4 coin tubes. In order to
guarantee a reliable payout of coins with different diameters, you can
choose the suitable tubes from various coin tubes with different diameters.
Measuring principle
Coins inserted into the coin validator pass sensors which check the coins
and there they generate individual measurement values. Due to a special
construction and arrangement of the sensors, each coin is checked for its
material properties and dimension. An upper limit and a lower limit are
stored for each coin type, a so-called acceptance band, so that the coin
validatorknowswhethertoacceptacoinornot.Ifthecoinvaluesmeasured
arewithin theacceptance band,thecoinisaccepted forsale,butif theyare
outside the band, it is rejected and directed into the return area.

National Rejectors, Inc. GmbH, Buxtehude
Programmed coin channels
Thecoinvalidatorhas16„memorylocations“forcoinacceptancewhichcan
be assigned up to 16 different coin types or tokens. These „memory
locations“are called coin channels. The acceptance band of a coin type/
token is allocated to a coin channel and the coin type/token is accepted in
that channel.
To be able to reject false coins reliably, channels with a narrow or even a
very narrow acceptance band are frequently set up for a coin type, in
additiontothe standard coin channel. The limits of thesecoinchannelsare
closer to one another so that false coins with similar measurements are
rejected. However, narrow und very narrow coin channels also accept less
genuine coins.
In addition it is possible to allocate coins with different measurements but
identicalcoinvaluestodifferentcoinchannels.Inthiswaythecoinvalidator
can, for example, accept one type of old and new coins.
However,a coin channelisnot only assignedtheacceptance bandandthe
coin value of one coin type but also other coin information which defines
further processing of the coin after its acceptance: e.g. inhibit and sorting
information.
Since in most cases the manufacturer’s customer-specific programming
does not take up all the coin channels, channels which are still vacant can
be assigned coin values and the desired further information at any time
using the programming station (WinEMP).
Thecoinvalidatorofferstwomemoryblocksconfiguredindependentlyfrom
one another and including 16 coin channels each (see section "Selecting
memory block 0 and 1 with DIL switch" in this chapter).
The label indicates which coin types are assigned to which channels (see

Inhibiting coin channels with DIL switches
The 16 coin channels can be inhibited by means of the setting module
(Pro 15, see chap. 8). In addition, it is possible to inhibit the channels 1–8
by means of DIL switches, which are situated on the rear of the coin
validator.Inordertogetfreeaccesstotheswitchingblock,thecoinvalidator
must be removed (see fig. 3). In order to inhibit a channel, push the
corresponding switch to the right to the ON position (fig. 4).

With DIL switch 9 of the switching block the G-46 can be switched
over to MDB-protocol, if it is fitted with a coin validator G-40.4000
from /3 upwards. This may be necessary when a new validator has
to be installed in a changer with an old MDB interface module.

Selecting memory block 0 and 1 with DIL switch
The G-46 can manage two memory blocks 0 and 1 which are
configured independently. Each block has been allocated 2 times
16 coin channels with different coi values, sorting and inhibiting
information etc. The blocks are programmed according to
customers’requirements at NRI. Always only one block is active
and can be used for coin validation.
Using DIL-switch 10 of the switching block, memory block 0 or 1
can be activated:
1. Remove the coin validator from the device at the top (fig. 3).
2. For block 1 set DIL-switch 10 into the right-hand ON position,
for block 0 into the left-hand position (OFF) (fig. 5).
3. Reinstall the coin validator.
4. Switch off and on the power.
The required memory block is activated.
