Hopper

Series

Coin Controls’ Universal Hoppers

were first introduced in 1984

The

MkII

and Mklll models

proved themselves to be

exceptionally reliable, with high

count accuracy. The Mk4 is the

latest generation of this

extremely successful series.

The Mk4 Universal Hopper can

be used as a direct replacement

for Mkll and Mklll Hoppers. Any

specific variances are clearly

indicated, where.appropriate, in

this manual. When ordering Mk4

Universal Hoppers as a

replacement, it is important to

specify which version is being

replaced.

Safety

Note-

Mk4 Hoppers

only

To meet the requirements for

EN 60950 the equipment must

be installed according to the

following requirements:

The equipment must be

protected by a 3A fuse.

The equipment must be supplied

from a SELV limited power

source.

The equipment must be installed

in an enclosure but positioned so

that it is external to any fire

enclosure area within the main

enclosure.

GENERAL

DESCRIPTION

1.0

1.1

Description

The Universal Hopper is an

“intelligent” large capacity coin

and token dispenser ideal for a

wide range of applications

including Gaming, Vending and

Transportation systems.

Mkll

and Mklll hoppers will

handle most coins in the range

16mm

30mm diameter and

1.25mm

3.5mm

thick, giving

the following approximate

capacities:-

Coin Size Capacity

DiameterThickness

28.4mm

2.21 mm 800 approximately

24.25mm

1.75mm

1600 approximately

The Mk4 has extended the range

to include 31 mm diameter and

1 mm thick coins.

The rate of payout, whilst being

dependent on the coin

dimensions and also the volumes

of coins in the Hopper at any

given time, is approximately

3 coins per second.

Precise payout is ensured

through optical sensing and

verifying of coin dispensing with

an electronic security signal

which alerts against coin jams,

failed sensors and bad power

supply. LED indicators are

provided for easy visual checking

of power supply, security status

and coin sensors.

The Universal Hopper has the

in-

built facility to operate in 3

modes:-

Mode 0

the direct switching mode.

Mode 1

the hopper is controlled directly

by a LOGIC CONTROL LINE.

When the line is ‘active’, the

motor runs.

Mode 2

the hopper is driven by pulses on

the control line which allows the

hopper to be used in place of a

solenoid payout with no software

and few hardware changes.

1.2

Options

There is a standard Universal

Hopper handling coins in the

diameter range of 21 mm

30mm, and the small coin

Universal Hopper handling coins

in the diameter range of 16mm

21 mm. Both of these models

can be supplied with a number

options:-

.2.1

Connector Position

The

12-pin

connector can be in

one of two positions, either on

the opposite side of the coin exit,

known as the standard position,

or on the same side as the coin

exit, known as the adjacent

position.

1.2.2

Level Sensing

Universal Hoppers can be

supplied with a choice of coin

sensing positions, these can be

either:-

High level or

Top level

All Hoppers are automatically

supplied with a low level function

to indicate coin starvation.

1.2.3

Connector Options

Mk4 Universal Hoppers are

available with connectors

compatible with Mkll and Mklll

Hopper installations. It is

important, when ordering, Mk4

Hoppers as a replacement to

specify which version is being

replaced.

All of the above options must be

specified when ordering.

1.3

Installation

Important: Power should not be

applied until the installation is

complete.

Secure the base plate in

position, using the six fixing

holes. The hole positions are

shown in Fig.1 1 b.

2. Wire up the base plate

connector to the host machine

see section 6.2 for connector

details, and sections 4

5 for

interfacing recommendations.

NOTE:

The

wire to be used should have

a maximum length of 3 metres,

and must be capable of handling

the maximum currents and

voltages specified in section 6.

3. Slide the hopper into the

baseplate and ensure that the

two halves of the connector are

securely mated.

4. Turn on the power.

1.4

Safety

1. Do not put a hand into the

hopper while the motor is running.

2. Static

It is possible for coins paid out to

have a static charge on them.

Coins should be discharged to

earth before being presented to

the user.

IMPORTANT:

The hopper should not be

installed/removed from

baseplate with power connected.

Avoid inhalation of coin dust

during any servicing operations.

MECHANICAL

DESCRIPTION

2.0

2.1

General

The hopper is mounted in a

machine via the base plate.

Electrical connection to the

hopper is made via the 12 pin

socket on the base plate which

mates with the corresponding

plug on the hopper body.

Coins are stored in the

cashbox

section of the hopper and fed

onto the elevator belt via a

passage in the centre plate. The

cut-out in the centre plate has

been designed to regulate the

flow of coins onto the belt. The

stirrer agitates the coins in the

coin box in order to minimise the

occurrence of bridging.

The elevator belt is driven by a

motor, gear box, and idler gear.

Coins are picked up at the

bottom of the belt and carried up

to the exit window. Optical

sensors in the exit window

detect the coins as they roll out

of the hopper.

A cable connects the main

control board to the 12 way

socket and carries all power

supplies and control signals.

access

To service the track, and 12 Pin

Plug, follow instructions below and

refer to figures 12(a) for Mk4 and

12(b) for Mkll and Mklll.

Mkll and Mklll Hoppers may

be fitted with a metal strut.

Removal of the strut will

require the coin box to be

removed first, see 2.4.

Remove the trackguard if

fitted, see 2.3

Note how wiring is laid out

and whether plug is on the

left or the right of the centre

plate (there should be a plug

blanking plate in the side not

used).

Place flat on a bench (coin

box face down) and remove

the fixing screws.

Remove end plate

Remove idler gear

Pull the track off the centre

plate.

Reassemble by placing the

track in the recess provided

in the centre plate, making

sure that the leg of the ‘L’

shape on the track plate is

against the centre plate. To

test the track is seated

correctly, spin it, if it jams this

means that one or more of

the legs are not in the recess.

Refit idler gear, taking care

not to disturb the track.

PCB Access

Mkll and

Mklll

PCBs are located

between the end and centre

plates.

NOTE:

Mkll

boards are

hard-

wired to the exit window and

cannot be removed without

unsoldering the 12 way header.

The Mk4 PCB is located in the

coin box. To access the board,

remove the coin box as

described in 2.4.

ELECTRONIC

DESCRIPTION

3.0

3.1

General Electronic

Description

Operation of the hopper is

controlled by a

4-bit

micro-

processor. The microprocessor

allows the choice of 3 different

operating modes. It also provides

the motor control drive via a

darlington bridge and an optical

payout detection output.

Separate power supplies are

recommended for the motor

supply input and the logic supply

input.

3.2

Operating Mode Selection

Three modes of operation are

available, selected via inputs IN1

and IN2 (pins 4 and 8 of the 12

way connector). Input signals

may be controlled by the host

machine, or may be hardwired.

Additionally, input IN3 (pin 12) is

the logic control line, used in

modes 1 and 2. These inputs are

passive pull-up active pull-down.

The signals therefore default to

logic ‘1’ if left open circuit.

NOTE:

It is strongly recommended that if

these inputs are to be controlled

by the host machine, then open

collector NPN transistors,

referenced to logic OV (connector

pin 2) be used to set the input

levels to

IN1,

IN2 and IN3.

With the exception of ‘RESET’

mode which can be applied at

any time (with instantaneous

effect) mode selection is

determined at power-up. The

hopper allows a 1

OOms

time-out

after power-up, then reads the

inputs IN1 and

IN2.

The hopper

will remain in the selected mode

until the power is removed, ie,

any further changes in the levels

at IN1 and IN2 will be ignored.

See fig 1

Refer to section 5.5 for

recommendations for driving input

signals on pins

IN1,

IN2 and

IN3.

FIGURE 1: Mode selectlon input logic

3.2.1

Mode 0

This is the default operating

Mode, and is selected when all

of the input selectors are left

open circuit.

When the 24V line is established,

the motor starts in the forward

direction and when the 24V

power line is removed, the motor

is braked.

3.2.2

Mode 1-W Logic Control

In this mode the logic and

24V power supplies can be

permanently connected and

motor function is determined via

a logic level on the IN3 input.

When IN1 (pin 4) and IN2 (pin 8)

are pulled down to logic OV at

power up, mode

is selected.

The operation of the motor is

now controlled via a logic signal

on IN3 (pin 12). With the 24V

supply present, a low level on

IN3 starts the motor and a high

level on IN3 brakes the motor.

3.2.3

Mode 2

Coin Counting

In this mode, the hopper will pay

out a coin for every pulse it

receives on input

IN3.

Mode 2 is selected by setting

IN1

(pin 4) high and IN2 (pin 8)

low at power up. Once selected,

the processor continually scans

input IN3. When a pulse is

detected on

IN3,

an internal

coin is paid out, it is detected

and the register is decremented.

The motor is started when the

internal coin register is non-zero

and is stopped when it returns to

zero. The maximum count for the

coin register is 4095

coins. Should

the 24V line fail at

any point, the motor is braked.

When the 24V line re-appears,

the payout of coins continues

until the coin register returns to

zero. Coin counting on IN3 can

take place while coins are being

paid out.

5ms

5ms Min

I-

FIGURE 2: Inputs to IN3

A pulse is defined as a falling

edge followed by a rising edge.

Pulse edges may be no closer

than 5ms (see fig.2). This is so

that the processor has adequate

time to poll the IN3 pin and

de-

bounce. This represents a

maximum pulse rate of 1

00Hz.

There is no lower limit. The

waveform duty cycle is

unimportant.

At power-up in mode 2, IN3 is

high. The first falling edge will be

recognised as the first pulse and

the hopper motor will start

running.

Pulsing on IN3 should not

commence earlier than

130ms

after the logic supply has been

established. This will allow for the

power-up time-out of 1

00ms

and

further processing time prior to

running the main program.

3.3

Reset Function

The reset function is available on

Mklll

and, when specified on the

Mk4 version.

In this mode the Hopper is reset,

i.e. processor reset and motor

drive disabled. This function is

provided as added security

enabling the host machine to

immediately stop the Hopper

irrespective of its mode of

operation.

Whilst in this mode connecting

IN3 (Pin 12) to ground turns the

exit window sensor off in order to

test it is operative. Confirmation

would be given as a signal

output on Pin 3 and 11 of the 12

Pin connector.

3.4

Optical Sensors

Optical sensors are fitted in the

exit window to detect coin

payout.

The signal on Pin 11 is the ‘Raw’

coin output signal. A de-bounced

coin output is available on Pin 3.

When no coins are present at the

exit window, the optical sensors

are clear, the output transistors

are open circuit, and the LED

indicator is off. Coins passing the

optical sensors obstruct the light

path causing the output

transistors to pull down to OV

and the LED indicator lights.

3.5

Optical Security Feature

The output of the optical sensor

is monitored by the

microprocessor and if the sensor

remains obstructed for more

than one second, the motor will

be braked and will remain off

until either the sensor is cleared

or power down takes place. This

action will result if a coin jams in

the exit window or if the optical

sensor fails which could be

checked by toggling IN3 in Reset

mode.

If the security feature should

operate, the security output on

output pin 5 and LED2 will be

switched off. The optical security

feature operates identically in all

3 modes.

3.6

Motor Operation

The DC motor is controlled by

the processor via a transistor

bridge. The motor will run

provided that one of the sets of

conditions shown below is met. If

any single condition fails then the

motor is braked and remains so

until all conditions become true,

or a power down occurs.

Mode 0 Motor Start Conditions:

Security feature true

24V line true

Mode 1 Motor Start Conditions:

Security feature true

24V line true

IN3 input low

Mode 2 Motor Start Conditions:

Security line true

24V line true

Internal coin count non-zero

When braking is initiated and for

whatever reason, 50ms braking

is carried out even if the fault

condition recovers before that

time. This guarantees that the

motor is stationary when the

bridge drivers change state, so

that no excess current flows in

the motor windings.

3.7

Motor Current Limit

The motor current is monitored

by the processor. When the

motor initially starts a high

current flows generating

maximum torque to force the

coin belt up to speed. After a

short time the motor current is

reduced to a fraction of the initial

surge current.

At any time after the initial surge,

if the current rises above a preset

value, then a jam is deemed to

have occurred. The motor is

braked for 50ms then reversed

for

150ms.

After a further 50ms

braking, the motor is started in

the forward direction. The current

is tested after 1

00ms

and if the

jam has not been cleared the

reversing cycle will be repeated.

This action will continue until the

jam has cleared. This reversing

action is effective in clearing

jams.

One further action is to test the

current in the reverse direction

during the final 50ms of the

reversing cycle. If during that

time period an overcurrent is

detected, then the motor will be

braked for 50ms and then

disabled for 1 second. This

action limits the duty cycle

sufficiently in the case where a

jam is solid in order to prevent

motor damage.

3.8

Coins With Holes

The

Mkll

hopper has not been

designed to handle coins with

holes and cannot be guaranteed

to perform correctly with such

coins.

The Mklll hopper can count most

coins with holes correctly, but

requires a jumper, on the control

board, to be set in the right

position for small or standard

coins

see below.

FIGURE 3: Label PCB Edge View

TIIIOINIAIL

If a Mklll hopper is converted

from one coin size to the other,

the jumper position must be

altered also. This is achieved by

removing the track guard, as

described in 2.3, placing the

jumper in the required positions,

then refitting the track guard.

REQUIREMENTS

4.0

4.1

Power Supply

For ease of use and maximum

noise suppression, the 0 volt

logic line (pin 2) and the motor 0

volt line (pin 1) are not

commoned

inside the hopper.

This means the outputs from the

hopper (OPT0 and security) are

noise free.

4.1

Suggested Connection

A suggested connection

diagram is shown in fig 4.

A twisted wire pair is

recommended for the motor

power leads to reduce the

radiated noise.

The TIP 126 arrangement shown

would only be required for mode

0 operation where power line

interruption is the method of

motor control. In modes 1 and 2

the power line can be left

permanently on and the TIP 126

and IK and

4K7

resistors can be

omitted.

4.1.2

EMC

The

Mklll

hopper is EMC

hardened. There is a version of

Mk4 hopper which is also EMC

hardened. This is to help users

to meet the European EMC

regulations (EN50081

EN50082).

Further precautions should be

taken with the installation to

minimise the effects of electrical

noise, i.e.

i) Max cable length = 3 metres

ii) All wires to the hopper should

be bundled together.

Output Sensor Interfacing

Both sensor outputs are open

collector NPN transistors, as

shown in Fig.5.

When a coin is paid out, the raw

sensor output will switch on,

connecting output Pin 11 to OV,

The sensor output on Pin 3 will

switch on approximately 5 ms

later

see Fig.6. Both outputs

will stay switched on until the

coin has left the exit window.

The open collector outputs are

provided for easy interfacing to

TTL,

CMOS or Relay inputs.

see fig. 7.

NOTE:

A flywheel diode is required on

any output which has an

inductive load connected, e.g. a

relay. A 30V maximum can be

tolerated on these outputs

(positive with respect to

0V).

5.2

Motor Switch Off Time

When using the hopper in mode

0 (see section 3.2.1) the host

machine applies power to the

motor and monitors the payout

sensors, disconnecting the

motor power when it has

counted out the correct quantity

of coins. The motor power

should be removed within

10ms

of the leading edge of the o/p.

Similarly, to avoid erroneous

payout in mode 1, IN3 should be

taken high within

10ms

of the

leading edge of the opto output

(pin 3).

5.3

Security Output

The security output is an open

collector NPN transistor which

should be connected as shown

in Fig.5 In normal operation the

transistor will be switched on, i.e.

the output pin will be connected

to OV. The transistor will switch

off if a fault is detected

Level Sense Plates

Brass plates are used for level

sensing. One plate is connected

to the logic 0 volts and the other

plates are wired to the 12 way

connector

pin 7 for low level;

pin 6 for either high or top level.

See figure 8. The signal levels on

these pins will be determined by

IN3,

if used, should always be driven

via an open collector transistor

referred to logic OV. IN1 and IN2

can also be driven via open

collector transistors (see fig. 9) or

if no change of mode is required,

then strapped to logic OV or left

depending on the mode

required.

LED Indicators

Three LED indicators are fitted

on the hopper. On

Mkll

Supply Notes

Important

The specified maximum

motor and logic + ve voltages

must not be exceeded,

otherwise damage/injury

could result.

Hopper speed (and payout

rate) varies with applied motor

voltage

The power supply fall time is

critical if the hopper is being

used in mode 0. When the

host machine has counted

out the required number of

coins, it must disable the

+24

volt supply. The motor is not

disabled until the power line

falls below a preset level of

18 volts DC, therefore there is

a danger of extra coins being

paid out if the power supply

fall time is greater than 5ms.

A power supply switching

device such as a transistor,

darlington or mosfet is

therefore recommended.

The standby current is the

current drawn when the

motor is disabled, e.g. if the

coin register is zero in mode 2

or if IN3 is high in mode
