1. INTRODUCTION AND DESCRIPTION OF COMPONENTS
This manual contains the technical information on the rotating hoppers in the U series.
A rotating hopper from the Useries is an intelligent mechanism designed for paying out a
determined type of coin. It works in combination with another intelligent mechanism that
governs it and of which the hopper is part (gaming, vending, parking machines, etc).
In the rest of this technical manual the rotating hoppers in the Useries will be
referred to as hopper or hoppers
These hoppers have a multicoin extraction system. The multicoin concept defines the fact that
these hoppers can return or pay out a coin whose measurements are: from 12 to 32 mm in ø
and 1.2 to 3.5 mm in thickness.
1.1 TECHNICAL CHARACTERISTICS AND A DESCRIPTION OF
COMPONENTS
The most relevant technical and performance characteristics are:
ÔMulticoin extraction system.
ÔPower supply of 12Vdc or 24Vdc. The current draw is:
12Vdc ±10% 24Vdc ±10%
Motor running without load 450 mA ±20% 310 mA ±20%
Start up 3 A ±20% 3 A ±20%
ÔCoin counting using infrared optic sensors.
ÔCoin payout speed of up to 8 coins per second.
ÔThree different size high capacity coin bays and the possibility of increasing this
capacity using supplements.

Small hopper Medium hopper Large hopper
L=115 mm and 250 coins L=115 mm and 400 coins L=115mm and 600 coins
ÔMicroprocessor controlled PCB control board.
ÔAnti jam and anti span systems.
Jams. These hoppers have a current draw detection system to manage the possible
coin jams that may occur. When the detection system activates, the spin of the hopper
motor is reversed for 1.5 seconds to free the jammed coins.
Spans. The time span between the extractions of two coins is called a span. When a
span of more than five second is detected, the hopper reverses the movement of the
motor for 1.5 seconds to move the coins in the coin bay so that after the movement
the coins are in a better position to be extracted.
ÔAuto detection of errors and faults. Depending on the communication protocol used,
the number of errors that are detectable will be different.
ÔA useful life of 2 million coin extractions.
ÔDifferent systems to control the filling if the hopper: optic sensors, mechanical scales
or overflow.
ÔEmpty detection using optic sensors.
ÔDifferent communication protocols with the machine: serial or parallel.
When using parallel protocol the machine manages all the signals separately: one
wiring loom for each hopper.
When using cctalk communication protocol, the communication is carried out through a
bidirectional data line (DATA). This solution radically simplifies the wiring and therefore
the cost of the machine.

Technical Information: HOPPER U 4
ÔTwo hoppers can be configured in cascade to maximise the use of space within the
machine.
ÔThe configuration of the node addresses is carried out using the dip switches situated
on the PCB which is situated on the underside of the hopper, as shown in the
illustration.
When using Cctalk protocol, address 1 is the machine, 2 is the validator, 3 is the
first hopper, 4 is the second hopper, 5 is the third hopper, 6 is the fourth hopper,
etc.

nodes.

2. Moving flap
This element is used to move the coins and dose the flow of coins that reach the extractor disk.
Another function is to avoid the pressure of an excessive number of coins on the extractor disk.
3. Mechanical supplement of greater capacity for the coin bay
This element is a coin bay accessory that increases its capacity. There are different models and
sizes for each of the different types of hoppers.
4. Hopper full detection system
There are three ways of controlling when the hopper is at full state:
Overflow: a mechanic system that is based on the overflow of coins using gravity. The
coin capacities of these hoppers are the following:

Infrared photocells: an electronic system that uses two infrared photocells.
Scales: based on controlling the weight of the coins in the hopper. When the weight of
the hopper full of coins compresses the spring, which is regulated with a screw, a micro
switch is activated. The Scales are an accessory of the hopper that are installed on the
underside and incorporate a base for its correct installation.

The application of these control systems is not possible in all the hopper models. Refer to the
following table:

Hopper type Photocells Overflow Scales
Small yes no Yes
Medium Yes Yes Yes
Large Yes yes Yes
5. Hopper empty detector
This system is based on management by an electronic infrared photocell. This system can be
applied to all the hopper models.
6. 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.
7. 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.
These hoppers can have two types of trigger:
Trigger without a roller: for coins with a diameter of over 30 mm.
Trigger with a roller: for coins with a diameter of equal to or less than 30 mm.
8. Control PCB
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 voltage and/or the different control systems for filling or

emptying the hopper of coins.
9. Extractor disk
There are three different coin extractor disks. The three accept the same thickness coins which
are between 1.2 mm minimum and 3.5 mm maximum.
Disk with 8 ridges and a red pivot: for coins with diameters between 18 and 30 mm.
This disk can reach a payout speed of 5.3 coins/second.
Disk with 12 ridges and a yellow pivot: for coins with diameters between 12 and 20
mm. This disk can reach a payout speed of 8 coins/second.
Disk with 7 ridges and a black pivot: for coins with diameters between 20 and 32
mm. This disk can reach a payout speed of 4.6 coins/second.
10. Drive motor for the extractor disk
This motor spins the disk so the coin can be extracted from the hopper. Its electrical
characteristics are as follows:
Current draw
12 Vdc 24 Vdc
Rest 75 mA 75 mA
Start up 3 A 2.5 A
Spinning 450 mA 310 mA
11. Base
This element is a hopper accessory that is used to join the hopper to the machine in which it is
installed. It has all the necessary holes to fix it to the machine and clips to hold the hopper for
fast assembly/disassembly.
12. Infrared photocells for counting coins
On leaving the hopper the coins cut an infrared beam generated by these photocells. The pulse
is considered correct when the duration is 18 milliseconds minimum. If the exit pulse is above
one second it is considered an error and the hopper will be put in out of order state.
13. Disk Support
This element houses the coin extraction system, PCB and the coin bay.
14. Housing
This element covers and protects all the different elements that are installed in the front part of
the hopper.

It also guides the coins toward a second hopper when two hoppers are mounted together in the
configuration called “cascade”.

3. CLEANING AND MAINTENANCE
The maintenance required for the hopper can be summed up as:
- General cleaning of the apparatus after 500,000 coin extractions
- It is recommended to clean the coin exit area where the optic sensors are more
frequently. This can be done with cotton wool bud dipped in alcohol.
WARNING:
ÔNever use products that contain benzene hydrocarbons. These products severely
degenerate the plastic parts producing irreparable damage.
ÔNever submerge the Discriminator series hopper in any liquid.
