GENERALINFORMATION
General information about the hopper currenza h2
The electromechanic hopper currenza h2is a coin payout system for
machines.Dependingonthemodelandthecointypeitcancollect2,000and
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.
Thehopper modelsh2L andh2X areprojected andcannot be
deliveredyet.
The hopper is fitted with a machine interface, that can be configured for
parallelorserialccTalk operation accordingtorequirements.In thecaseof
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.
Ifthehopperistobefilledautomatically,itcaninteractwithacoinvalidation
system without any problems (e.g. NRI coin validators G-13.mft, G-40 or
NRI coin changers c2, E-66/A-66, G-46).
The currenza h2features
• Models in various sizes for a coin capacity as high as possible
depending on the machine dimensions
• Space-saving dual hopper installation thanks to coin passage
• switchable machine interface for parallel or serial ccTalk operation
• Suitable for paying out a lot of different coin types
• Payout speed of up to 7.5 coins per second
• Operating safety due to coin payout sensors, automatic error
detection and anti-jam function

Overview of the device

14 National Rejectors, Inc. GmbH, Buxtehude
DESIGN
Fig. 2b:Payoutdisc
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
coinsfromthebowlintothecoinoutlet [2a/9]bymeans
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
Thecoinpassage [2a/8]letsthecoinspasspaidoutbyanadditionalhopper
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
installthehopperinthemachine(seeChap. 5"Start-
up").
Interfaces

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
servicecover)youcanchangetheoperatingmode(ccTalk/parallel)andthe
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
• Hoppercontrol
• Anti-jamfunction
• 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
coinvalidationsystem.Thefunnelformofthebowlandthesafetyflapdirect
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.Thehopperthuspaysoutcoinsuntilthevoltageisincreasedagain.
Fig. 3a: Control signal to hopper
Coinsignaltocontrol system
The hopper transmits a short signal (30 ms) to the control system via the
coinline(voltagedrop),wheneverthesensorlocatedinfrontofthehopper's
coin outlet is covered by a coin.
Fig. 3b: Coin signal(s) to control system during control signal to hopper
Errorsignaltocontrolsystem
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
Theredpilotlightflasheswith every error signal, sothattheerroriseasy 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
"Machineinterface"inChap. 8"Technicaldata"andtheccTalkspecification
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
thatthecoinsaresplitteduponthetransportdiscandcanbepaidoutagain
when rechanging the rotational direction.
If the coin accumulation and pressure onto the payout disc is so high, that

(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).

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.
Ifthehoppersaremountedaccordingly,thecoinspaidoutbytherearhopper
