1. INTRODUCTION
This manual contains the technical information on the rotating hoppers in the
Hopper U-II. The following models are included in this family of products:
-Hopper U-II ccTalk
-Hopper U- II ccTalk encrypted
-Hopper U-II ccTalk plus
-Hopper U- II ccTalk plus encrypted
-Hopper U-II parallel
-Hopper U-II parallel plus
The rotating Hopper U-II is a result of the redesigning process of the traditional
Hopper U, obtaining an optimised version of the hopper. This product is 100%
compatible with the previous Hopper U model.
This document contains all the characteristics of this new product, concentrating
especially on the benefits this hopper provides in comparison to the traditional
Hopper U.
2. GENERAL DESCRIPTION.
A rotating hopper of the U- II series is an intelligent mechanism designed for the
return or payout of change of a particular coin type. It works in combination with
another intelligent mechanism that governs it and of which it forms part (gaming,
vending, parking machines, etc).
These hoppers have a multicoin extraction system. The multicoin system is
defined as a system that allows these hoppers to payout a coin whose dimensions
are between 12 and 32 mm in diameter and 1.2 to 3.5 mm thick.
The product is highly reliable, and has a useful life that guarantees a minimum of 2
million coin extractions.

2.1. CAPACITY OF THE HOPPER U-II.
The quantity of coins that can be stored in the coin bay of the hopper depends on
the model. There are 4 different models in the series that provide a range of coin
capacities. There is also the possibility to increase their capacity by the use of
supplements.
Small hopper
Medium Hopper
Intermediate hopper
Large hopper
L=115mm and 250
coins
L=154 mm and 400
coins
L=189 mm and 525
coins
L=228mm and 600
coins
Coins of Ø 24 mm
and thickness 2.8

Coins of Ø 24 mm
and thickness 2.8 mm
Coins of Ø 24 mm

Figure 1. Hopper U-II
Consult section “COIN BAY”to see the exact capacities depending on the size of the
coin, and also the supplements.
2.2. RANGE OF COINS.
The multicoin extraction system of the hopper U-II, guaranties the payout of coins
whose dimensions are between 1.2 and 3.5 mm thick, and 12 to 32 mm in ø.
Consult section “

7
VERSION 2.0
06 - 2011
COIN EXTRACTOR DISK”for more details.
2.3. DETECTION OF FULL AND EMPTY
The Hopper U-II has detection mechanisms that detect the full and empty levels of
the coins in the coin bay.
The detection of empty is done by using an electronic infrared photocell system.
(See details in section “COIN LEVEL DETECTORS.)
The detection of full is carried out in two different ways:
-Using two infrared photocells that work in the same way as the empty detection
photocells. (See details in section “COIN LEVEL DETECTORS.).
-Using electromechanical scales. (See details in section “4.13.3.
Electromechanical scales.”).
2.4. DOUBLE COUNTING.
The Hopper U-II has a coin exit control system that provides added protection
against attempts of fraud. When the Hopper U-II has this mechanism installed, it is
called Hopper U-II plus.
It is a mechanism based on an optic system that controls the movement of the
trigger, in a way that the exit of the coin is announced by this mechanism and
confirmed by the optic sensor that counts the coins. This mechanism is available for
the Hopper U-II parallel, and for the Hopper U-II ccTalk.
2.4.1 Hopper U-II plus ccTalk.
When any anomaly occurs, which could be an attempt at fraud, it will be
communicated by the Hopper U-II plus ccTalk as a reply to the ccTalk error
command “163 Test Hopper” (See details in the manual “Protocol ccTalk Hopper
U-II”)
It is possible to transform a standard Hopper U-II into a Hopper U-II plus with a kit.
Once the kit is installed, it is only necessary to change the position of dipswitch 7
(to ON) so that the standard U-II standard works as a Hopper U-II plus.

VERSION 2.0

2.4.2 Hopper U-II plus parallel.
When any anomaly occurs, which could be an attempt at fraud, it will be
communicated by the Hopper U-II plus parallel using the corresponding error
commands (see details in the manual “Protocol parallel Hopper U-II”).
It is possible to transform a standard Hopper U-II into a Hopper U-II plus with a kit.
Once the kit is installed, it is only necessary to change the position of dipswitch 7
(to ON), this is explained in “¡Error! No se encuentra el origen de la referencia.
2.5. PAYOUT SPEED
The Hopper U-II pays out up to 8 coins per second. This speed varies with the
different disks used. See details in section “

9
VERSION 2.0
06 - 2011
COIN EXTRACTOR DISK”.
2.6. PROTOCOLS
The Hopper U-II can work with parallel protocol (parallel) and ccTalk protocol. To
see the parallel Hopper U-II protocol, consult the manual “Parallel Hopper U-II
Protocol”
To see the ccTalk Hopper U-II protocol, consult the manual “ccTalk Hopper U-II
Protocol”
2.7. IN-LINE CONFIGURATION.
Two hoppers can be configured in line with one another to maximise the use of space.
Figure 2. Configuration of the Hopper U-II in line.
Figure 3 indicates the positions that the bases of the Hopper U-II should be placed
to achieve optimum performance of the two hoppers in line.

VERSION 2.0

Figure 3. Position of the bases of two Hoppers U-II in line.
2.8. ANTI-JAM AND ANTI-SPAN SYSTEMS
Jam. The hopper has a current draw detector that, when there is a coin jam,
reverses the spin direction of the disk motor for 1.5 seconds to free the jammed
coins.
Span. The name given to the time between the extraction of two coins. When the
hopper detects a time span of more than 5 seconds the hopper reverses the spin
direction of the disk motor for 1.5 seconds to move the pile up of coins in the
hopper and get them into a position to be extracted.

Figure 7. Components of the Hopper U-II.
4.1. COIN BAY
The coin bay is where the Hopper U stores the coins and where they are extracted
from when ordered to do so by the machine. Its design allows the storage of the
maximum number of coins in the minimum space, taking into account that even the
last coin can be extracted.
There are various models with different capacities.

4.2. MOVING FLAP.
This element moves and doses the flow of coins that move from the coin bay to the
extractor disk.
The flap is fixed to the coin bay at the top and the lower part rests on the axis of
the disk. This way the spinning disk transmits a rocking motion to the flap that
moves the coins in the hopper; this movement moves the coins towards the
extraction system. For coins of more than 29 mm in diameter, a different flap is
used; it is called the short flap (it allows the bigger coins to pass under the flap to
reach the extractor disk). This flap is not recommended for use with smaller coins
as it will allow too many coins to reach the disk causing problems with their
extraction.
Figure 8. Types of flaps
4.3. COIN LEVEL DETECTORS.
The Hopper U-II has full and empty detection sensors.
Empty detection.
Empty detection is carried out by a photocell (photodiode and phototransistor) that
is located in the holes at the bottom of the coin bay.
The photodiode emits a beam of light that is detected by the phototransistor when
there are no coins in the hopper. When the coin level is lower than the height
established for the photocells, the control board detects this and advises the
machine.
Large flap
Small flap

VERSION 2.0

Full detection.
Full detection, as with the empty detection, is carried out by a photocell
(photodiode and phototransistor) that is located in the holes at the top of the coin
bay.
The photodiode emits a beam of light that is detected by the phototransistor when
the coin level is lower than the photocells. When the coin level is higher lower than
the height established for the photocells, the control board detects this and advises
the machine.
The application of this system is possible in all the hopper models.
4.4. BLADE.
The function of this element is to slice between the coin and the disk making the
coin leave the hopper. The hoppers can have two types of blade:
Long blade: for disks of 7
and 8 ridges.
Short blade: for disks of 12
ridges.
Figure 9. Types of blade
Both models have a metallic reinforcement which is held on the blade with a screw.

4.5. TRIGGER.
In the coin extraction process this device compresses the trigger spring and at a
certain point it shoots the coin out of the hopper.
The Hopper U-II has only one type of trigger, whereas previous models had two. It
is made of plastic.
4.6. CONTROL BOARD.
This element governs the hopper and communicates with the machine. The wiring
looms that correspond to the counting, filling and emptying functions and motor are
connected to it. There are different models depending on the protocol used (ccTalk
or parallel) and its operation with Azkoyen tools.
4.6.1. CcTalk control board. Switches and connectors.
There is only one model of the board for all the Hoppers U-II ccTalk.
