U3 HOPPER – TECHNICAL INFORMATION 1
1. INTRODUCTION
This manual contains the technical information of the U3 Hopper. The follo ing models are
included in this range of products:
- U3 Hopper ccTalk.
- U3 Hopper MDB.
The U3 Hopper is the result of development to incorporate ne security features for the most
demanding environments. This device is 100% compatible ith the previous U-II Hopper model
and maintains all its key features such as reliability, versatility, speed, accuracy and minimal
maintenance.
This document details all the features of this ne product, ith particular emphasis on its ne
benefits.
2. GENERAL DESCRIPTION
The U3 series rotating hopper is an intelligent mechanism designed for the return or pay-out of
a particular coin type. It orks in tandem ith another intelligent mechanism that controls it
(master) and the machine into hich it is integrated (gaming, vending, parking meters, etc.).
These Hoppers have a multicoin extraction system. The multicoin concept defines the ability of
these devices to return a round coin without holes hose outer dimensions are ithin the
specified diameter and thickness ranges. In other ords, the same Hopper model can be used
for different types of coins, although there can only be one type of coin inside.

U3 HOPPER – TECHNICAL INFORMATION 2
2.1. CAPACITY OF THE U3 HOPPER
The quantity of coins that can be stored in the coin bo l 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 using supplements.

2.2. RANGE OF COINS
The multicoin extraction system of the U3 Hopper, guarantees the pay-out of round coins
without holes hose dimensions are ithin the range of diameter and thickness specified. The
range of coins accepted depends on the type of disk used.
Consult section 4.7 COIN EXTRACTOR DISK for more details.

U3 HOPPER – TECHNICAL INFORMATION 3
Only EURO coin range has been tested. For other coin denominations please
contact the sales area manager or after sales department.
2.3. DETECTING FULLNESS AND EMPTINESS
The U3 Hopper has the option to incorporate detection mechanisms to detect the storage level
of the coins in the bo l.
•Option 1: Using infrared photocells system. There is the option to incorporate photocells
at the top and the bottom of the coin bo l. At the bottom, there are t o positions
available (See details in section 4.3 COIN LEVEL DETECTORS).
Fi ure 1 - Level sensor positions.
•Option 2: Using electromechanical or electronic scales. (See details in section 4.14.3
ELECTROMECHANIC SCALE, 4.14.4 SLAVE ELECTRONIC SCALE and 4.14.5 STANDALONE
CCTALK ELECTRONIC SCALE).
The only option to guarantee a reading of complete emptiness is using
the Electronic Scale

U3 HOPPER – TECHNICAL INFORMATION 4
2.4. PAYOUT SPEED
The U3 Hopper pays out up to 6.3 coins per second. This speed varies ith the different disks
used.
Cavities of the disk Speed
9 5.2 coins / second
12 6.3 coins / second
Table 4 - Pay-out speed per disk
2.5. COMMUNICATION PROTOCOL
The U3 Hopper orks ith ccTalk or MDB protocol, depending on the product reference. Consult
the manual “ccTalk Pro ocol - U3 Hopper”. For information about MDB protocol please contact
Azkoyen.
2.6. IN-LINE CONFIGURATION
T o hoppers can be configured in line ith one another to maximise the use of space.
Fi ure 2 - Confi uration of the U3 Hopper in line.
Figure 2 indicates the positions that the bases of the U3 Hopper should be placed in order to
achieve optimum performance of the t o hoppers in line.

Fi ure 3 - Position of the bases of two Hoppers U3 in line.
NOTE: The bases of U3 Hopper and U-II Hopper are 100% compatible.
2.7. ANTI-JAM AND ANTI-SPAN SYSTEMS
•Jam: The hopper has a current dra detector that, hen there is a coin jam, reverses
the spin direction of the disk motor to free the jammed coins.
•Span: The name given to the time bet een the extraction of t o coins. When the
hopper detects a time span of more than 5 seconds, it 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.

3.6. ELECTRICAL DIAGRAMS AND PINOUT
The U3 Hopper uses a type 5 connector indicated by the ccTalk general specification. It is a 10-
pin connector (2x5) of 2.5mm pitch, Molex 8624 or similar. The U3 Hopper has t o different
connecting versions depending on the part number of the product: united or separated po er.
The “separated po er” allo s the user to use an independent po er supply for po er circuit
and logic circuit. This distribution feature increases the reliability of the communications,
therefore reducing the interferences generated by the motor that could affect to the logic
control circuit and the communications.
There are t o PCB versions depending on the po er connection. The pinout of the connectors
for the t o versions are as follo s:

The follo ing scheme sho s ho the machine should connect the hoppers in “separated
po er” configuration:
Fi ure 8 - General dia ram for power separated hoppers
The GND terminals of both supplies (GND_POWER and GND_LOGIC) must be connected on the
machine side (externally to the Hopper). The hopper is able to absorb a voltage difference
bet een GND_POWER and GND_LOGIC, due to the voltage drop along the cables, of up to ±2.5
Volts.
Even though the ne feature of separating the po er requires a pinout of the U3 Hopper, hich
differs from its predecessor U-II Hopper, it is still compatible.
In order to guarantee the po er demand of the motor and the use of flat iring ith a small
section from many manufacturers, a ne pair of pins for POWER circuit has been added: PIN 2
(GND_POWER) and PIN 6 (VDC_POWER).

4.1. COIN BOWL
The coin bo l is here the U3 Hopper stores the coins and, is also from here they are extracted
hen ordered to do so by the machine. Its design allo s to be stored the maximum number of
coins in the minimum space, considering that even the last coin can be extracted.
There are various models ith different capacities. See section 2.1 CAPACITY OF THE U3
HOPPER for more details.

4.2. MOVING FLAP
This element moves and regulates the flo of coins that move from the coin bo l to the
extractor disk.
The flap is fixed to the coin bo l at the top, and the lo er part rests on the axis of the disk. This
ay the spinning disk transmits a rocking motion to the flap that moves the coins in the hopper;
this movement moves the coins to ards the extraction system.
The moving flap depends on the coins to be managed. The normal flap is used in disks of 9 slots
(also called cavities) and the large flap is used in disks of 12 slots, here small coins are managed.

Fi ure 10 - Types of flaps
4.3. COIN LEVEL DETECTORS
The U3 Hopper has the option to incorporate optic detectors to detect the level of coins stored
into the bo l.
•Bottom level detection
Bottom detection is carried out by a photocell (photodiode and phototransistor) that is located
in the holes at the bottom of the coin bo l. There are t o positions to connect the sensors.
The photodiode emits a beam of light that is detected by the phototransistor hen there are no
coins covering the beam. When the coin level is lo er than the height established for the
photocells, the control board detects this and notifies the machine.

U3 HOPPER – TECHNICAL INFORMATION 14
•Top level detection
Top detection, as ith the bottom detection, is carried out by a photocell (photodiode and
phototransistor) that is located in the holes at the top of the coin bo l.
The photodiode emits a beam of light that is detected by the phototransistor hen the coin level
is lo er than the photocells. When the coin level is higher than the height established for the
photocells, the control board detects this and notifies the machine.
This system can be implemented in all the hopper models.
4.4. BLADE
The function of this component is to glide bet een the coin and the disk, thus making the coin
leave the hopper. The hoppers can have t o types of blade.
Blade 1.5 Short blade
Fi ure 11 - Types of blades
All the models have a metallic reinforcement hich is scre ed onto the blade.
