1 The most important information first
Brief information on the 4-tube coin changer
The 4-tube changers of the G-46 series are designed for application in
vending and service machines. By changing the connecting cable and/or
the interface module, they can easily be adapted to different machines.
They support the following machine interfaces:
• 2-price relay output (parallel interface)
• 4-price relay output (parallel interface)
• 4-price API (parallel interface)
• Simplex V (serial interface)
• BDV (serial interface)
• MDB (serial interface)
• VCCS (serial interface)
In comparison to the former 3-tube changers, the 4-tube changers do not
only have an additional tube, but also lengthened tubes, more coin channels
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.
Due to the modular design, you can individually combine your changer with
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
changer. Using the PC and Palm handheld programs the same functions
can be displayed and set, for these programs separate operating instructions
are at your disposal (see chap. 3 "Options").
The menu of the setting module is clearly divided into programming
functions (PRO), and service functions (SER). Some of the programming
functions (filling and emptying tubes) can also be carried out directly on the
device via the internal keyboard.

DESIGN AND FUNCTION OF THE G-46 G-46 MDB

National Rejectors, Inc. GmbH, Buxtehude
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
be rejected via the coin return. Otherwise, the acceptance gate opens to the
sorting system. The coin validator now checks if the coin is to be sorted into
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
validator knows whether to accept a coin or not. If the coin values measured
are within the acceptance band, the coin is accepted for sale, but if they are
outside the band, it is rejected and directed into the return area.
G-46 MDB DESIGN AND FUNCTION OF THE G-46
17
National Rejectors, Inc. GmbH, Buxtehude
Programmed coin channels
The coin validator has 16 „memory locations“ for coin acceptance which can
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
addition to the standard coin channel. The limits of these coin channels are
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
identical coin values to different coin channels. In this way the coin validator
can, for example, accept one type of old and new coins.
However, a coin channel is not only assigned the acceptance band and the
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).
The coin validator offers two memory blocks configured independently from
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
fig. 2).

National Rejectors, Inc. GmbH, Buxtehude
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. In order to get free access to the switching block, the coin validator
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).

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.

National Rejectors, Inc. GmbH, Buxtehude
Adding up credit which cannot be shown on the vending
machine display (Pro 0401)
If two different currencies are managed by the coin changer, the set
smallest coin value is seldom the lowest common multiple of both currencies.
The credit of the coins inserted during one sale, which can not be shown on
the vending machine display as it is not divisible by the smallest coin value,
can be added up nevertheless and taken into consideration during the
vending operation.
With the first place from the right-hand side of function Pro 0401 you set,
whether the credit, which cannot be displayed, is to be added up or not:
Pro 0401
00000000
Add up credit, which cannot be displayed (1),
reset credit (0)
Release of inventory keys via the machine control (Pro 0401)
Whether the inventory keys (L, ML, MR, R) of the internal keyboard are to
be disabled and enabled via the machine control or not, you set using the
third place from the right-hand side in function Pro 0404:

PROGRAMMING FUNCTIONS G-46 MDB
34
National Rejectors, Inc. GmbH, Buxtehude
Setting the sensitivity of the string sensor (Pro 21)
This function is of special interest for validators with string sensor. With
function Pro 21 you can change the sensitivity of the sensor. The maximum
sensitivity is set by a value of 00. With a value >50 the sensor is only
activated, when the acceptance flap is opened by the string or the coin.
Setting the maximum coin number per tube (Pro 25)
In the sub-functions 01 to 04 of Pro 25 you can set the maximum number
of coins to be collected by each tube. When the programmed number of
coins is achieved for a tube, all following coins for this tube will be led into
the cash-box. Only when coins have been paid out from this tube, is the tube
able to collect coins again.
When "0" is programmed, coins will be sorted into the tube until the upper
filling level sensors indicate "tube full".
For each tube a sub-function is assigned:
• Left tube Pro 2501
• Middle/left tube Pro 2502
• Middle/right tube Pro 2503
• Right tube Pro 2504
G-46 MDB PROGRAMMING FUNCTIONS

National Rejectors, Inc. GmbH, Buxtehude
Setting the security stock per tube (Pro 26)
In the sub-functions 01 to 04 of Pro 26 you can set the number of coins not
to be paid out for each tube. Usually, the default is 3. For critical coins the
set value can also be higher. When paying out, only values from 1 to 9 are
considered.
In function Pro 0401 you can determine, that also the security stock
can be paid out.
For each tube a sub-function is assigned:
• Left tube Pro 2601
• Middle/left tube Pro 2602
• Middle/right tube Pro 2603
• Right tube Pro 2604
The coin changer is set at the manufacturer so that the security
stock is not sent to the vending machine control, if the machine
control questions the tube filling level
(real filling level = sent filling level + security stock).
Setting the wake-up time (Pro 53)
For coin changers in battery operation and with an external wake-up line a
time period can be set in function Pro 53, which specifies how long the coin
changer remains switched on after having received the last message from
the vending machine (wake-up time).
After the wake-up time had passed the coin changer is switched off
automatically and must be re-waked by the vending machine which activates
the external wake-up line.
There are factors (1–255) to be set, which are multiplied with a time unit of
0,264 seconds. If the setting is ≤ 10 (= 2,6 seconds), a wake-up time of
30 seconds, set at the manufacturer, is applied.
PROGRAMMING FUNCTIONS G-46 MDB
36
National Rejectors, Inc. GmbH, Buxtehude
Setting of the coin sorting to the tubes (Pro 54–57)
In the functions Pro 54–57 you can adjust which programmed coin types are
to be sorted in which of the four tubes. Each tube has a corresponding
function:
• Left tube Pro 54
• Middle/left tube Pro 55
• Middle/right tube Pro 56
• Right tube Pro 57
The coin type to be sorted into a tube is defined via its channels (see label
in chap. 4 "Design and function of the G-46" for the assignment coin type
– coin channel).
• Channel 1–8 in tube L Pro 5401, 9–16 in tube L Pro 5402
• Channel 1–8 in tube M/L Pro 5501, 9–16 in tube M/L Pro 5502
• Channel 1–8 in tube M/R Pro 5601, 9–16 in tube M/R Pro 5602
• Channel 1–8 in tube R Pro 5701, 9–16 in tube R Pro 5702
Example:
Left tube (L) is to collect 2 Euro coins and no longer 1 Euro coins.
1 Euro coin is programmed in channels: 4 (normal), 8 (narrow), 11 (very narrow),
2 Euro coin is programmed in channels: 5 (normal), 9 (narrow)
All channels of the 1 Euro coin are set to "1":
Pro 5401 Pro 5401
10001000 00000100
8 .... 1 16 ... 9
All channels of the 1 Euro coin must be set to "0“ and those of the 2 Euro coin to "1“.
Pro 5401 Pro 5401
00010000 00000001
8 .... 1 16 ... 9
With this setting the 2 Euro and no longer the 1 Euro coin is sorted into the left
tube.
Only sort coins of the same value into one tube.
Make sure to consider all coin channels of a coin (normal and
narrow).
After changing the sorting, it may be necessary to adapt the tubes of the
payout set to the new coin (see chap. 12 "Repairing and exchanging
components").

Setting of the coin sorting to hoppers (Pro 70)
This function is only supported by MDB changers with hopper
interface.
With this function one coin out of channels 1 to 16 is assigned to hopper 1
or hopper 2. It is only possible to pay out one of the coin types from the
hopper, that is programmed as tube coin in the changer (see section
"Setting of the coin sorting to the tubes (Pro 54–57)" in this chapter. The
hopper is used, if one coin type is particularly often paid out as change.
For the coin channel of both hoppers a sub-function is assigned each (see
label in chap. 4 "Design and function of the G-46" for assignment coin type
– coin channel):
• Coin channel for hopper 1 Pro 7001
• Coin channel for hopper 2 Pro 7002
The hoppers must be enabled in function Pro 7101 (see next
