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 1/2" 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 f

2

. 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 f

2

has 32 coin channels that can be data­managed either in a single memory block or, when divided in 2 x 16 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 f

2

(see Chap. 8
"WinEMP programming station for the workshop/WinEMP compact for on­site 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.

FUNCTION

National Rejectors, Inc. GmbH, Buxtehude

4 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

17

National Rejectors, Inc. GmbH, Buxtehude

The last eight coin channels 25 to 32 (or 9 to 16 with double block data­management, 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 16 channels each, in two memory
blocks (double block data-management).

If the double block data-management has been configured, the f

2

can data­manage two separately programmed (memory) blocks 0 and 1. The 16 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 pile­up, coin acceptance is inhibited.

18

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

19

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 1-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: 100ms

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.

FUNCTION

National Rejectors, Inc. GmbH, Buxtehude

Fig. 3: currenza d

2

(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 d

2

datasheet).

The gates of an external sorting device are
controlled via two sorting control lines (pin 3 and

4) of the 10-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? 10–1000ms).

While the coin validator is sorting an accepted coin (= sorting time),
it cannot accept any further coins unless the same sorting path is
addressed.
If 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.

FUNCTION

21

National Rejectors, Inc. GmbH, Buxtehude

Coin enable/inhibition/Activation of narrow coin channels

If coins are to be no longer accepted for payment at the machine, you can
either

• inhibit all coin acceptance,

• inhibit all coin channels of a certain coin type so that this coin is no

longer accpeted, or

• inhibit the normal coin channel of a certain coin type so that the coin

will only be accepted in the narrow channel.

Enabling coins after reset
(currenza f2 ccTalk only)

Following a reset operation, the coin acceptance function of the currenza f

2

ccTalk is disabled and must be enabled again by the machine.

As a standard feature, the coin validator refuses each further
acceptance of a coin if the currenza f2 has not been addressed by
the machine within the last 500ms or if the last accepted coin has
not yet been polled by the machine.

Inhibit all/individual coin types via machine control system
(currenza f2 ccTalk only)

The machine can inhibit all coin acceptance (master inhibit). Then the coin
validator no longer accepts coins. However, the machine can also inhibit
only specific coin types (inhibit mask), e.g., if there is no more change in an
external payout unit or a coin type is very frequently replaced by false coins.

To find how to program these functions, please refer to the specification
"ccTalk Serial Communication Protocol, Generic Specification" (headers 231/

228) which is available on the internet at "www.ccTalk.org".

External common inhibit (currenza f2 parallel only)

The machine can inhibit coin acceptance via the (common) inhibit signal
line. The coin validator no longer accepts coins (see section "Interfaces" in
Chap. 9 "Technical data").

22

FUNCTION

National Rejectors, Inc. GmbH, Buxtehude

External inhibit of single coin types
(currenza f2 with parallel standard interface only)

As an alternative to individual inhibiting of certain coin channles via the DIL
switches of the coin validator the machine can inhibit coins or wide coin
channels using six single inhibit lines (see section "Interfaces" in Chap. 9
"Technical data").

Which coin or rather which coin channel is to be inhibited using which signal
line is customized by NRI.

Internal inhibit of single coin types/coin type groups

As an alternative to individual inhibiting of certain coin channels via the
machine you can on-site inhibit individual coin channels or even groups of
channels using the switching blocks on the coin validator (see section
"Inhibiting coins/Activating narrow coin channels" in Chap. 6 "Operation").

Alternatively: deactivate individual coin types on a long-term basis

Teach mode

Coin channels can be taught in the teach mode without configuration
software via the lower switching block on the coin validator, i.e. a coin
channel is reassigned a coin type or even a token. The new acceptance
band is generated by inserting the coins. For this you do not need to remove
the validator from the machine. For the teaching procedure, the last eight
coin channels are available (double block data-management: Coin
channels 9 to 16 of the activated memory block, single block data­management: Coin channels 25 to 32 (see also section "Single or double
block data-management" in this chapter and section "Teaching coin channels
in the teach mode" in Chap. 6 "Operation").

START-UP

23

National Rejectors, Inc. GmbH, Buxtehude

5 Start-up

For all installation work on the coin validator or the machine please observe
the following safety instructions:

The coin validator may only be connected by a qualified
electrician.

The coin validator is not suited for outdoor use.
Do not use the coin validator if the device or connecting cable

are damaged.
Select the correct voltage for the coin validator (see label).
Never pull the connecting cable of the coin validator from the

machine when a voltage is applied.
Pull out the machine’s mains plug before you install or remove

the coin validator.

In order that the coins inserted into the machine fall into the coin
validator so that they can be measured properly and not become
stuck in the validation area, the customer must provide a coin
feeder suited for the coin validator (design and positioning see
Fig. 5b).

To install the currenza f2 in a machine with parallel or serial ccTalk
interfaces:

1 Disconnect the machine from the mains supply.
2 Connect the coin validator to the machine using the appropriate

machine interface [5a/1, 3, 4] and connecting cable.

3 Hang the coin validator in the machine using the lateral mounting

studs [5a/2].

4 Install coin feeder provided by the customer above the coin validator

as illustrated in Fig. 5b. (Please also note the dimensions
recommended for the insertion of euro coins.)

Of importance!

If the coin feeder is not positioned accurately, the coins inserted
into the coin validator cannot be processed properly so that down
times and incorrect measurements may occur.

5 Reconnect the mains supply to the machine.

6 Operation

This chapter describes the operation, i.e. the setting of specific functions on
the coin validator:

• Selecting memory block

• Inhibiting coins/Activating narrow coin channel

• Teaching coin channels in the teach mode

The settings that are performed directly on the validator are described. To
find out how to perform settings using the configuration software WinEMP,
please refer to separate instructions (cp. also Chap. 8 "WinEMP programming
station for the workshop/WinEMP compact for on-site configuration" and
product accessory pages on the internet (www.nri24.com)).

Chapter 4 "Function" describes the function of the adjustable device
options.

Selecting memory block
(only with double block data-management)

If the coin validator is to access the other memory block and, e.g., accept
euro coins instead of national currency coins, the correct block can be
selected using the upper switching block:

To select memory block 0, move DIL switch S1.10 to the bottom (OFF)
position, for memory block 1, move it to the upper ON position.

Memory block 0 selected

Memory block 1 selected

OPERATION

National Rejectors, Inc. GmbH, Buxtehude

Inhibiting coins/Activating narrow coin channel ...

With double block data-management, using the two switching blocks on the
coin validator each of the 16 coin channels of the activated memory block
or each coin assigned to a specific coin channels can be inhibited, i.e. the
channels inhibited are no longer used for coin acceptance.

To activate a narrow coin channel the normal coin channel must be
inhibited. If both channels are enabled, the wider acceptance band of the
normal coin channel is used.

The first 8 DIL switches each inhibit the following coin channels:

Switching block S1

DIL switch off on

S1.1 Coin channel 1 accepts inhibited
S1.2 Coin channel 2 accepts inhibited
S1.3 Coin channel 3 accepts inhibited
S1.4 Coin channel 4 accepts inhibited
S1.5 Coin channel 5 accepts inhibited
S1.6 Coin channel 6 accepts inhibited
S1.7 Coin channel 7 accepts inhibited
S1.8 Coin channel 8 accepts inhibited

Switching block S2

DIL switch off on

S2.1 Coin channel 9 accepts inhibited
S2.2 Coin channel 10 accepts inhibited
S2.3 Coin channel 11 accepts inhibited
S2.4 Coin channel 12 accepts inhibited
S2.5 Coin channel 13 accepts inhibited
S2.6 Coin channel 14 accepts inhibited
S2.7 Coin channel 15 accepts inhibited

S2.8 Coin channel 16 accepts inhibited

If all coin types are to be accepted for payment by the machine unlimitedly,
the DIL switches S1.1–S1.8 and S2.1–S2.8 of the two switching blocks are
in the lower (OFF) position. If you want to inhibit a coin channel, you only
need to move the respective DIL switch toward the top to ON.

Example

The coin validator is no longer supposed to accept the coin(s) assigned to coin
channels 3 and 10, which means that coin channels 3 and 10 must be inhibited

With the DIL switches in these positions, the coin validator no longer accepts the
coin type(s) assigned to coin channels 3 and 10!

If a normal coin channel and a narrow coin channel have been
programmed on the coin validator for one coin type, the normal coin
channel must be inhibited as described above in order to activate
the narrow coin channel. If both channels are enabled, the wider
acceptance band of the normal coin channel is used.
If the coin type is to be inhibited, both coin channels must be
inhibited.

To inhibit coin channels on the validator:

1 Unhook the coin validator from the machine.
2 Inhibit the desired coin channels using DIL switches S1.1–8 and

S2.1–8 (cp. example above).
The desired coin channels are inhibited.

3 Hang the coin validator back in the machine.

28

OPERATION

National Rejectors, Inc. GmbH, Buxtehude

Teaching coin channels in the teach mode ...

A coin channel can be assigned a token or a new coin either using the lower
switching block on the coin validator or in ccTalk mode using ccTalk
commands and the machine service menu.

... using switching block on the coin validator

In order to generate new acceptance bands you can teach up to eight coin
channels using the lower switching block on the coin validator. You will need
at least ten coins/tokens of the new type.

There is a different switch assignment for the double and single block data­management:

Switching block S2 (with double block data-management)

DIL switch off on

S2.1 Coin channel 9 – teach
S2.2 Coin channel 10 – teach
S2.3 Coin channel 11 – teach
S2.4 Coin channel 12 – teach
S2.5 Coin channel 13 – teach
S2.6 Coin channel 14 – teach
S2.7 Coin channel 15 – teach
S2.8 Coin channel 16 – teach
S2.9 Teach mode switch off switch on

S2.10 Acceptance band normal wide

Switching block S2 (with single block data-management)

DIL switch off on

S2.1 Coin channel 25 – teach
S2.2 Coin channel 26 – teach
S2.3 Coin channel 27 – teach
S2.4 Coin channel 28 – teach
S2.5 Coin channel 29 – teach
S2.6 Coin channel 30 – teach
S2.7 Coin channel 31 – teach
S2.8 Coin channel 32 – teach
S2.9 Teach mode switch off switch on

S2.10 Acceptance band normal wide

By default, the eight teach channels of the currenza f2 with parallel standard
interface have been programmed, so that one coin impulse is transmitted
to the machine via coin signal line 6, when a new coin is accepted (cp.
section "Interfaces" in Chap. 9 "Technical data").

the current switch settings so that you can restore them easily for
the normal operating mode at the end.

1 Set all DIL switches S2.1–10 toward

the bottom to OFF.

2 Set DIL switch S2.9 toward the top to

ON.
Now the device is in teach mode to
teach the coin channels.

3 Enable the coin channel to be taught

(9–16 or 25–32, here: 11 or 27) by
setting the appropriate DIL switch
(S2.1–8, here: S2.3) toward the top to
ON.

4 Insert at least 10 coins of the new coin type/token into the coin

validator or machine.
After the 10

th

coin has been inserted, the acceptance gate is
operated once (brief clacking sound). Additional coins can be
inserted.

Now you can save the measured values generated by the inserted coins in
either a normal (a) or a wide (b) acceptance band. A wide acceptance band
is an appropriate choice when you only have a limited selection of coins at
your disposal for the purpose of teaching tokens.

To save with the normal acceptance band:

5a) Set DIL switch S2.9 toward the

bottom to OFF.
Successful saving is signalled by
the acceptance gate attracting once, an error when saving is indicated
by the acceptance gate attracting twice (brief clacking sounds), if, for
example, the acceptance band of the coins inserted and the
acceptance band of an already programmed coin channel overlap.

To abort the operation, first set the DIL switch of the respective coin
channel (here: S2.3) and then DIL switch S2.9 toward the bottom to
OFF.

OPERATION

National Rejectors, Inc. GmbH, Buxtehude

To save with a wide acceptance band:

5b)Set DIL switch S2.10 toward the

top to ON.
The acceptance band has been
widened.

Now you can set DIL switch S2.9
toward the bottom to OFF.
Successful saving is signalled by
the acceptance gate attracting once, an error when saving is indicated
by the acceptance gate attracting twice (brief clacking sounds), if, for
example, the acceptance band of the coins inserted and the
acceptance band of an already programmed coin channel overlap.

To abort the operation, first set the DIL switch of the respective coin
channel (here: S2.3) as well as DIL switch S2.10 and then DIL
switch S2.9 toward the bottom to OFF.

6 If necessary, set DIL switches S2.1–8 for the normal operating mode

(see section "Inhibiting coins/Activating narrow coin channel" in this
chapter).

The new coin type/token will now be accepted for payment by the coin
validator.

... using ccTalk commands/machine service menu

In order to generate new acceptance bands you can teach coin channels
using a ccTalk instruction set (see section "Teach mode" in Chap. 9
"Technical data"). Applying this instruction set (headers 202/201) the teach
mode can be started and monitored, e.g. via a service menu.

The new acceptance bands are generated and stored by inserting ten coins/
tokens of the new type. After having stored the acceptance bands the new
coin type/token will be accepted for payment by the coin validator.

For all further information on teaching coins/tokens using the service menu
please refer to the machine manual.

If you overwrite a coin channel in the teach mode which has
already been configured, you must adapt all features assigned
to this channel (e.g. coin ID, sorting, etc.) to the new coin/
token (see separate WinEMP manual).

National Rejectors, Inc. GmbH, Buxtehude

7 Maintenance and service

In this chapter you will find out how to

• clean the currenza f

2

and

• remedy the cause of a malfunction.

Cleaning coin validator

The coin validator must only be wiped clean from time to time with a damp
cloth (lukewarm water with some detergent). Beyond that, no further
maintenance work is required.

Under no circumstances may the cloth be so wet that fluid
runs into the device. Otherwise the PCB will be damaged.
Do not use any solvents or scouring agents that will attack the
plastic material of the device.

1 Pull the machine’s mains plug.
2 Carefully open the flight deck [6/1] from the top and hold it open.
3 Use a cloth to wipe off the coin runway [6/2] inside the coin validator.
4 Close the flight deck again.
5 Reconnect the machine to the mains supply.

MAINTENANCE AND SERVICE

National Rejectors, Inc. GmbH, Buxtehude

Remedy, hints

• Connect ribbon cable to coin validator
and machine correctly

• Supply machine with voltage

Open flight deck and clean coin runway
(see section "Cleaning coin validator" in
this chapter)

• Make sure that (common) inhibit signal
line is not activated by machine (see
section "Interfaces" in Chap. 9 "Technical
data")

• Make sure that the single inhibit signal
line assigned to the coin is not activated
by the machine or the correct single
inhibit line is assigned (if necessary,
correct with WinEMP) (see section
"Interfaces" in Chap. 9 "Technical data")

• Make sure that machine control system
does not inhibit using ccTalk command

• Make sure that coin is not inhibited using
the DIL switches on the rear of the
device or not only the narrow coin
channel is enabled and the normal one is
inhibited (see section "Inhibiting coins/
Activating narrow coin channel" in
Chap. 6 "Operation")

Possible causes

No power supply

Coin runway dirty

Coin inhibited

Troubleshooting

Malfunctions can occur in all electronic devices. These do not always have
to be faults in the device. In many cases the reason is improper connections
or incorrect settings. Therefore: please first of all check, whether the
malfunction can simply be remedied using the following table:

GLOSSARY

National Rejectors, Inc. GmbH, Buxtehude

Glossary

Acceptance band A range of acceptable measured values of one → coin type

(with specific → coin properties) defined by an upper and
lower limit value.

Acceptance gate The acceptance gate diverts the inserted coins into the

acceptance or return area of the coin validator.

Accepted coin sensors The accepted coin sensors are positioned in front of the cash

coin outlet of the coin validator and check whether accepted
coins fall unhindered into the cash-box chute.

Attraction duration The attraction duration is used to specify the period of time

for which the solenoid is to attract the → acceptance gate in
order to guide the accepted coins to the cash-box or an
external sorting device.

Block → Memory block

Channel → Coin channel

Coin acceptance band → Acceptance band

Coin channel Coin channels are used to describe → coin types using their

different → coin properties (alloy, size, etc.). The required
coin properties of a coin type are defined in → acceptance
bands which are assigned to the coin channels for further
processing along with other coin information.

Coin impulse length By specifying a certain coin impulse length, with which the

signals are transferred from the parallel coin validator to the
machine, the coin validator can be adjusted to the specific
processing time of the respective machine.
If coin impulses of different length are assigned to the
individual → coin channels in order to differentiate among
the coin types, the → coin impulse number is always equal
to one and cannot be varied.

49

GLOSSARY

National Rejectors, Inc. GmbH, Buxtehude

Coin impulse number Every coin accepted by the coin validator passes on an

impulse to the machine control system via the appropriate →
coin signal line. An impulse tells the machine control system
that a coin has been accepted. In principle, 255 impulses per
coin can be assigned to the → coin channel that is assigned
to a coin. However, it only makes sense to assign more than
1 if the machine control does not have sufficient coin signal
lines and if higher-value coins have to be simulated by a
multiple of coin impulses, i.e. when e.g. a 2-euro coin is
inserted, 4 coin impulses would be sent to the machine
control via the coin signal line allocated to the 50-cent coin.

Coin properties Coin properties which are measured when a coin is inserted

into the coin validator. These are e.g. material, thickness,
volume, minting, diameter, mass, hardness, etc.

Coin signal line Coin signal lines are used to transmit the → coin value of a

→ coin type from the coin validator with parallel interface to

the machine.
For information about the coin signal line of the → SGI model
see → credit line.

Coin type One coin type includes all coins for which the → coin

properties agree.

Coin value The value of a → coin type that is transmitted to the machine

in case of a parallel interface as (a) coin impulse(s) via →
coin signal lines and in case of a ccTalk interface using
ccTalk coin type 1–16 and coin ID.

Common inhibit signal With the parallel standard model the machine control system
line can block acceptance of all coins using this signal line. The

validator will no longer accept any coins.
For information about common inhibit of the → SGI model
see → inhibit line.

Credit line The → SGI coin validator uses the credit line to transmit the

→ coin value or a → coin type to the machine.

For information about the coin line of the parallel standard
model see → coin signal line.

Data block download When updating a data block (set) (2 data blocks) using

WinEMP, the data blocks for the connected coin validators
are loaded quickly and easily from the internal hard disk of
your PC into the coin validator. By doing this, a new data
block is loaded into → memory block 0 (and memory block 1).
The new data blocks contain different coin and device
configurations, e.g. current limit values of the → acceptance
bands for a currency or new inhibiting or sorting information.

ECV Electronic Coin Validator

Impulse length → Coin impulse length

Impulse number → Coin impulse number

Inhibit line With the parallel → SGI model the machine control system

uses this signal line to inhibit all coin acceptance. The
validator will no longer accept any coins.
For information about common inhibit of the parallel standard
model see → common inhibit signal line.

Memory block Memory of the coin validator. At the manufacturer's company,

a customer-specific setting is programmed to determine
whether the 32 → coin channels of the currenza f

2

are to be
data-managed in one memory block (single block data­management) or, when divided into 16 channels each, in two
memory blocks (double block data-management). Two
(memory) blocks 0 and 1 can be used to data-manage two
independent configurations of coin/device data (e.g. two
currencies). However, for coin validator operation, only one
memory block with 16 channels can be active at a time; the
other block is inhibited.
The memory block(s) can be updated using WinEMP (→
data block download).

Sense line The → SGI coin validator uses the sense line to signal that

a coin is valid after having passed the measurement and
validation area, even if the machine inhibits the coin via the
→ inhibit line.

Sorting control line To sort the cash-box coins with an external sorting device,

the coin validator has sorting control lines.

Sorting gate The sorting gates are activated in the coin validator depending

on the run time of accepted coins and direct the coins to be
sorted into the coin return or coin outlet towards the cash-box
or external sorting device.

Sorting time The sorting time specifies the switching times of an external

sorting device.

Switching blocks The two switching blocks are located on the rear of the coin

validator and incorporate 10 DIL switches each. Each switch
has a specific function, e.g. inhibiting individual or grouped
→ coin channels.

Teach mode In the teach mode, the last eight → coin channels can be

assigned new → coin types or → tokens on site at the
machine without any configuration tool by inserting the new
coins, which means that these newly configured coins are
accepted in the respective coin channel for payment.
With the ccTalk model the teach mode may be controlled
either using the → switching blocks on the coin validator or
ccTalk commands and the machine service menu.

Tilt line The → SGI coin validator uses the tilt line to transmit error

signals.

Token Tokens are accepted for payment at machines instead of coins

in a currency.
