GENERAL INFORMATION

General information about the hopper currenza h

2

The electromechanic hopper currenza h

2

is a coin payout system for

machines. Depending on the model and the coin type it can collect 2,000 and

more coins, in order to be able to pay out these coins as change on

command of the machine control system. Due to its high capacity the

hopper is used in machines, that have to pay out certain coins as change

frequently, such as money changers, vending and amusement machines.

The hopper models h

2

L and h

2

X are projected and cannot be

delivered yet.

The hopper is fitted with a machine interface, that can be configured for

parallel or serial ccTalk operation according to requirements. In the case of

the parallel interface the hopper communicates with the machine control

system using signal lines, whereas the ccTalk interface allows the hopper

to use the serial ccTalk data transfer protocol to communicate with the

control system as slave. The interface is configured according to customer

requirements on delivery.

The reliable and low-maintenance payout mechanism in the form of a

rotating disc driven by a motor is designed extra ruggedly, so that it

withstands innumerous coin payouts permanently.

If the hopper is to be filled automatically, it can interact with a coin validation

system without any problems (e.g. NRI coin validators G-13.mft, G-40 or

NRI coin changers c

2

, E-66/A-66, G-46).

The currenza h

Models

Most notably the hopper models differ in the coin capacity. All models can

be equipped with or without full or empty recognition and be fixed onto two

different mounting brackets depending on the machine dimensions.

Coin capacity (S/M/L/X)

The hopper capacity is defined by shape and depth of the bowl and the front

bowl cover.

The four hopper sizes S, M, L, and X are made up of two different sized bowls

and two appropriate front covers for each bowl. The width and the height of

the hopper is always the same (cp. Chap. 8 "Technical data"). The hopper

size is embossed on the front cover (see Fig. 1a).

Full and empty recognition

All hopper models are available with empty or full recognition or with empty

and full recognition.

The recognition is put into effect using electric contacts in the hopper bowl

(not available for retrofitting), which are closed by the coins from a certain

filling level on or up to a certain filling level (cp. Chap. 4 "Function").

• all parts which you need to operate and start up the hopper.

Overview of the device

14

National Rejectors, Inc. GmbH, Buxtehude

DESIGN

Fig. 2b: Payout disc

Bowl and front bowl cover

The bowl [2a/10] and bowl cover [2a/3] build the hopper funnel, which

collects the coins, in order to feed the rotating disc (Fig. 2b), that pays out

the coins.

Rotor, payout disc, and safety flap

The payout disc (Fig. 2b) driven by a rotor directs the

coins from the bowl into the coin outlet [2a/9] by means

of metal pins inserted in the disc.

In order to protect the rotating parts against access

during operation and transport the coins optimally, the

bowl is provided with a safety flap [2a/1].

Coin passage

The coin passage [2a/8] lets the coins pass paid out by an additional hopper

and thus serves as second coin outlet (see section "Space-saving dual

hopper assembly (coin passage)" in Chap. 4 "Function").

Mounting bracket

The mounting bracket [2a/6] (Fig. 2c) is used to

install the hopper in the machine (see Chap. 5 "Start-

up").

Interfaces

For detailed information on the parallel or serial ccTalk machine

interface [2a/12] and on the connector for the empty and full

recognition [2a/16] please refer to Chap. 9 "Technical data" (cp. also section

"Hopper control" in Chap. 4 "Function").

Fig. 2c: Mounting brackets

15

National Rejectors, Inc. GmbH, Buxtehude

DESIGN

Jumpers

Using the jumpers [2a/14] on the rear of the hopper (accessible by service

cover) you can bridge certain pins of the machine interface so that the

hopper works no longer in the parallel but in the ccTalk mode or vice versa

(see section "Configuring operating mode (parallel/ccTalk)“ in Chap. 6

"Operation").

Pilot lights

The three pilot lights [2a/7] on the rear of the hopper indicate the operating

state or a malfunction):

Green LED Hopper is receiving control signal and activates

motor and payout disc (see Fig. 2c)

Yellow LED Hopper is paying out coin and transmits coin signal

to control system

Red LED Error (number of signals indicates error type, see

section "Troubleshooting" in Chap. 7 "Maintenance

and service")

Switching block

Using the switching block [2a/15] on the rear of the hopper (accessible by

service cover) you can change the operating mode (ccTalk/parallel) and the

ccTalk hopper address, if you want to provide the machine with several

hoppers (see sections "Configuring operating mode (parallel/ccTalk)" and

"Selecting ccTalk hopper address" in Chap. 6 "Operation").

FUNCTION

4 Function

This chapter describes the functional principle of the hopper:

• Coin reception and payout

• Hopper control

• Anti-jam function

• Protection against cable break (parallel interface only)

• Space-saving dual hopper assembly (coin passage)

• Empty and full recognition (optional)

Coin reception and pay out

The coins of a particular type are either filled in the hopper bowl before

starting up the hopper or continuously sorted into the bowl by an upstream

coin validation system. The funnel form of the bowl and the safety flap direct

the coins to the rotating payout disc uniformly. The disc conveys the coins

from the bowl via the coin outlet to the return area by means of metal pins

inserted in the disc.

Hopper control

Depending on the interface configuration the hopper is controlled either

using signals transmitted via the lines of the parallel interface or using a

serial data transfer protocol (cp. also section "Configuring operating mode

(parallel/ccTalk") in Chap. 6 "Operation").

Control, coin, and error signal (parallel interface only)

The machine control system communicates with the hopper using three

signal lines: control line, coin line, and error line (see section "Machine

interface" in Chap. 8 "Technical data").

17

National Rejectors, Inc. GmbH, Buxtehude

FUNCTION

Control signal to hopper

If the hopper is in standby mode (after start-up), the machine may activate

the hopper motor at any time by transmitting a signal via the control line

(voltage drop). The motor turns the payout disc as long as the signal is

present. The hopper thus pays out coins until the voltage is increased again.

Fig. 3a: Control signal to hopper

Coin signal to control system

The hopper transmits a short signal (30 ms) to the control system via the

coin line (voltage drop), whenever the sensor located in front of the hopper's

coin outlet is covered by a coin.

Fig. 3b: Coin signal(s) to control system during control signal to hopper

Error signal to control system

The hopper detects malfunctions such as coin jams or defective plug

connections/cables, and informs the control system by transmitting a

certain number of short signals via the error line (voltage drop, 1:1 pulse

pause ratio, 10 ms; 100 ms between pulse intervals of 1–8 pulses).

FUNCTION

The red pilot light flashes with every error signal, so that the error is easy to

locate and correct (see sections "Pilot lights" in Chap. 3 "Design" and

"Troubleshooting" in Chap. 7 "Maintenance and service").

ccTalk data transfer protocol (ccTalk interface only)

The control system communicates with the hopper using the serial ccTalk

protocol. For more details about the ccTalk protocol please refer to section

"Machine interface" in Chap. 8 "Technical data" and the ccTalk specification

at www.ccTalk.org.

Anti-jam function

The hopper detects, if the coins can no longer be transported due to a jam.

In this case it changes the rotational direction of the motor for 1.5 sec., so

that the coins are splitted up on the transport disc and can be paid out again

when rechanging the rotational direction.

If the coin accumulation and pressure onto the payout disc is so high, that

the motor can no longer turn the disc, the rotational direction is changed for

0.5 sec. and, if necessary, for further full seconds until the jam has been

removed.

Protection against cable break (parallel interface only)

If an end of the coin line of the connecting cable between hopper and control

system is open (e.g. cable break or improper plug connections), the hopper

no longer pays out coins and transmits an error signal to the control system

(see section "Hopper control system" in this chapter and section

"Troubleshooting" in Chap. 7 "Maintenace and service").

In the control system the coin line must be pulled up to 5V using a

pull-up resistor (e.g. 10k

Ω).

19

National Rejectors, Inc. GmbH, Buxtehude

FUNCTION

Space-saving dual hopper assembly (coin passage)

Thanks to the coin passage between the hopper's rear cover and coin

payout unit it is possible to install two hoppers in the machine side by side

and as close as possible.

If the hoppers are mounted accordingly, the coins paid out by the rear hopper

can be directed into the return area of the machine through the coin passage

of the front hopper. In this case the front hopper uses the coin passage as

second coin outlet (see section "Aligning two hoppers with coin passage" in

Chap. 5 "Start-up").

Empty and full recognition (option)

All hopper models can be equipped with an empty or with an empty and full

recognition.

Empty recognition

The hopper uses the empty recognition to signal the control system that the

hopper must be refilled in order to be able to pay out further coins.

The filling quantity is monitored by electric contacts

in the hopper bowl or bowl cover (cannot be

retrofitted): If the hopper is full, the electric circuit

is closed by the coins abutted on the contacts

(Fig. 4). If the filling level declines below one of the

contacts, the circuit is interrupted.

The empty recognition is analyzed by the hopper

and transmitted to the control system (see section

"Interfaces" in Chap. 8 "Technical data" or ccTalk

specification at www.ccTalk.org).

As the parallel machine interface has only

one empty/full recognition line, but the hopper may be equipped with

both – empty and full recognition – in this case the contacts of at least

one recognition must be connected to the control system, so that the

control system is able to analyze the empty/full message (see section

"Connecting hopper" in Chap. 5 "Start-up"):

• internal empty recognition, external full recognition

• external empty recognition, internal full recognition

• external empty recognition, external full recognition

Fig. 4: Coins abutted on empty

recognition

20

National Rejectors, Inc. GmbH, Buxtehude

FUNCTION

Full recognition

The hopper uses the full recognition to signal the control system that no

more coins can be fed into the hopper, so that it does not overflow.

The filling quantity is also monitored by electric contacts in the hopper bowl

or or bowl cover (connot be retrofitted): If the filling level is below the contacts,

no current flows. If it is as high as the contacts, the electric circuit is closed

by the coins abutted on the contacts.

The full recognition is analyzed by the hopper and transmitted to the control

system (see section "Interfaces" in Chap. 8 "Technical data" or ccTalk

specification at www.ccTalk.org).

As the parallel machine interface has only one full/empty recognition

line, but the hopper may be equipped with both – full and empty

recognition – in this case the contacts of at least one recognition

must be connected to the control system, so that the control

system is able to analyze the full/empty message (see section

"Connecting hopper" in Chap. 5 "Start-up"):

• internal full recognition, external empty recognition

• external full recognition, internal empty recognition

• external full recognition, external empty recognition
