GENERAL INFORMATION
National Rejectors, Inc. GmbH, Buxtehude
Device functions which are set or prepared by the manufacturer
according to customer specifications and can be set or changed
using the NRI configuration software WinEMP (see Chap. 8
"WinEMP programming station for the workshop/WinEMP compact
for on-site configuration" and product accessory pages on the
internet (www.nri24.com)).
Device or accessory functions under project. Cannot yet be delivered.
Additional technical documentation
Apart from the manual you already have, there is further documentation for
the currenza f2, e.g. about spare parts, testing, and configuration. All
documentation is available in a compressed PDF format at www.nri24.com
(→ Download).
General information about the coin validator
The electronic coin validator currenza f2 in standardized 3 /2" format is
ideally suited for amusement, vending and service machines due to its
compact design and different machine interfaces.
The acceptance speed of up to ten coins per second is new with the
currenza f2. This acceptance speed is guaranteed by the shortest way
possible the coins pass to be measured in the coin validator: The coins are
measured in free fall. The integrated measuring sensors provide a quick
multiple scanning of the coins inserted for optimum material recognition and
evaluation of 24 measuring parameters and thus for reliable acceptance of
genuine coins and separating out of fraud coins.
Thanks to the coin validator’s flash technology software downloads to adapt
the measuring technology, coin data and control software can be executed
quickly and simply. The currenza f2 has 32 coin channels that can be data-
managed either in a single memory block or, when divided in 2 x 6 coin
channels, in two memory blocks with different coin configurations.
To be able to react as quickly as possible to new false coins and to enable
you to make your individual adjustments, the coin validator can be connected
to a PC programming station which is made up of the configuration and
diagnostics software "WinEMP" (including card reader and licence chip
card) and an NRI tester for power supply of the currenza f2 (see Chap. 8
"WinEMP programming station for the workshop/WinEMP compact for on-
site configuration").

Flight deck and measurement and validation area
A coin inserted into the machine initially passes the measurement and
validation area [2/5] of the coin validator (via a coin feeder (provided by the
customer)). Here the coin runs past inductive and optical sensors and
generate individual measurement values. Each coin is checked for its coin
properties and dimensions.
The flight deck [2/4] can be opened in order to remove a jam caused by coins
which have become stuck.
Pilot lights
The pilot lights [2/2] in the top right-hand corner of the coin validator indicate

FUNCTION
National Rejectors, Inc. GmbH, Buxtehude
Function
This chapter describes how the coin validator works:
• Coin acceptance and coin channels
• Single or double block data-management
• Accepted coin sensors
• Coin validator control
• Control for external sorting device
• Coin inhibition/Activation of narrow coin channels
• Teach mode
Coin acceptance and coin channels
The coin validator has 32 "memory slots" for coin acceptance which can be
assigned up to 32 different coin types or tokens. These "memory slots" are
termed 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.
In order to reject fraud coins reliably, frequently for one coin type, in addition
to the normal coin channel, channels with a narrow or even very narrow
acceptance band are set up. The limit values of these coin channels are closer
to one another so that fraud coins with similar measured values are rejected,
if the normal coin channel is inhibited (see section "Inhibiting coins/
Activating narrow coin channel" in Chap. 6 "Operation"). Narrow and very
narrow coin channels, however, also possess a lower acceptance rate.
In addition, it is possible to allocate coins with different measured values but
identical coin values to different coin channels. This is how the coin validator
can, for example, accept old and new coins of the same type.
However, a coin channel is not only assigned the acceptance band of a coin
type but also other coin information which defines further processing of the
coin after its acceptance: e.g. coin identification or signal line and impulse
number, inhibit information, sort information for an external sorting device.
Since in most cases the manufacturer’s customized programming does not
take up all the coin channels, channels which are still vacant can be
assigned coin types and further information desired at any time using the
configuration software. Existing configurations can be changed.

FUNCTION
7
National Rejectors, Inc. GmbH, Buxtehude
The last eight coin channels 25 to 32 (or 9 to 6 with double block data-
management, see section "Single or double block data-management" in
this chapter) are intended to be used for the teach mode. In these coin
channels new coin types can also be taught without configuration software,
directly via the switching blocks on the coin validator; i.e. a coin channel is
assigned a coin type or also a token (see section "Teach mode" in this
chapter).
Single or double block data-management
At the manufacturer’s company, a customized setting is programmed to
determine whether the 32 coin channels are to be data-managed in one
memory block or, when divided into 6 channels each, in two memory
blocks (double block data-management).
If the double block data-management has been configured, the f2 can data-
manage two separately programmed (memory) blocks 0 and . The 6 coin
channels can be assigned to each block with different coin types (also
currencies), sorting information, etc. However, only one block can be active
at a time and be used for the coin measurement and for further coin
processing. You can use the upper switching block on the device to select
the desired block (see section "Selecting memory block" in Chap. 6
"Operation").
Accepted coin sensors
To ensure that accepted coins actually arrive in the cash-box or in an
external sorting device and that coin acceptance has not been tampered
with, accepted coin sensors, positioned in front of the cash-box coin outlet
check whether the inserted coin drops unhindered into the cash-box chute.
Acceptance of a coin is not transmitted to the machine until the coin has
passed this checking function.
If the accepted coin sensors are continuously covered, e.g. by a coin pile-
up, coin acceptance is inhibited.

FUNCTION
National Rejectors, Inc. GmbH, Buxtehude
Coin validator control
Depending on the machine interface the coin validator is controlled either
using signals transmitted via the lines of the parallel interface or using a
serial data transfer protocol.
Transfer of coin values by means of coin impulses and via coin signal
lines (parallel interface only)
Each coin accepted by the coin validator passes on one impulse to the
machine control system on a coin signal line. The impulse tells the machine
control system that a coin has been accepted. The standard and SGI
interface differ in their coin signal lines:
currenza f2 with parallel standard interface
The parallel standard interface has six signal lines transmitting coin
impulses. Depending on the coin signal line controlled the machine knows
what the coin type (coin value) is (cp. also section "Interfaces" in Chap. 9
"Technical data").
The assignment between coin type and coin signal line is customized by
NRI.
You can also assign a certain combination of signal lines, i.e.
several signal lines, to a coin type in order to be able to
differentiate.
currenza f2 with parallel SGI interface
The parallel SGI interface always uses the same signal line to transmit coin
impulses (cp. also section "Interfaces" in Chap. 9 "Technical data"). In case
the f2 accepts more than one coin type coins with a higher denomination are
transmitted as multiple impulses (see section "Multiple impulses" in this
chapter).

FUNCTION
9
National Rejectors, Inc. GmbH, Buxtehude
Multiple impulses
If more coin types should be programmed than signal lines available, coin
types can also be assigned several coin impulses (multiple impulses) per
coin so that the machine no longer differentiates by the signal line (not with
SGI model) but by the impulse number. In such a case, coin types with a
higher denomination are assigned a multiple of a smaller coin, i.e. if, for
example, a 2-euro coin was inserted, the machine control unit would be sent
two coin impulses on the coin signal line assigned to the -euro coin.
The number of coin impulses is customized by NRI.
Coin impulse length
The length of the coin impulses that are sent from the coin validator to the
machine can be set individually to suit the machine.
Possible setting: 5 to 500ms, default setting: 00ms
You can also assign a different impulse length to each coin type, but
then only one impulse will always be transmitted and no multiple
impulses for the purpose of differentiating the coins (see section
"Multiple impulses" in this chapter).
ccTalk data transfer protocol (currenza f2 ccTalk only)
The machine control system communicates with the coin validator using the
serial ccTalk protocol. For more details about the ccTalk protocol please
refer to section "Interfaces" in Chap. 9 "Technical data" and the ccTalk
specification at www.ccTalk.org.

Fig. 3: currenza d2
(3-fold high-speed sorter)
Control for external sorting device
In order to be able to guide the accepted coins into
the cash-box or, e.g., into change tubes or hoppers,
you can equip the coin validator with the NRI
3-fold sorting device currenza d2 or with another
sorting device (cp. separate currenza d2
datasheet).
The gates of an external sorting device are
controlled via two sorting control lines (pin 3 and
4) of the 0-pole sorting interface [2/11] on the
rear of the device (see section "Interfaces" in
Chap. 9 "Technical data").
Assignment coin type – sorting control line and
sorting time (how long should the activating period
be? 0– 000ms).
While the coin validator is sorting an accepted coin (= sorting time),
it cannot accept any further coins unless the same sorting path is
addressed.
f an external sorting device is no longer required and the sorting
time is not set to zero, the coin acceptance speed will continue to
be reduced by the preset sorting time. For faster coin acceptance,
the sorting time should therefore be set to zero.
