Introduction
Money 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.
The Universal Hopper ‘Lite’ is a cost effective solution for standard applications. Unlike the other
Universal Hoppers, the ‘Lite’ has been designed to only work in Mode 1.
3.
Safety Note - MK4 Series 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
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 16.25mm - 30mm diameter and 1.25mm
- 3.5mm thick, giving the following approximate capacities:-
Table 1: Approximate Hopper Capacities.
Diameter
Thickness
Approx. Capacity
28.4mm
2.21mm
800
24.25
1.75
1600
The MK4 and ‘Lite’ have extended the range to include 31mm diameter and 1mm 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 a 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 (Not available on the ‘Lite’ version)
the direct switching mode.
Mode 1
the hopper is controlled directly by a LOGIC (Motor) CONTROL LINE. When the line is ‘active’, the
motor runs.
Mode 2 (Not available on the ‘Lite’ version)
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.

Installation
Important: Power should not be applied until the installation is complete.
1. Secure the baseplate in position, using the six fixing holes. The hole positions are shown in
Figure 18.
2. Wire up the baseplate connector to the host machine - see section 12.3 for connector details,
and sections 8.8 & 10 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 12.
3. Slide the hopper into the baseplate and ensure that the two halves of the connector are
securely mated.
4. Turn on the power.
6.1
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.
3. 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
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 baseplate 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, gearbox, 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.

See Figure 14.
Firstly, locate cut away slots in Centre plate and End plate at the base of the track guard
opposite the PCB. Push track guard up to reveal a gap between body moulding and the guard.
Insert broad flat bladed screwdriver or equivalent into gap and gently lever out the guard until the
leading edge is above the outside edge of the body mouldings. Now slide the guard down
towards the cut out and gradually withdraw it. Slide back the track guard to refit.

Issue 3.1 – Feb 2006
Electronic Description
8.1
General Electronic Description
Operation of the hopper is controlled by a 8-bit microprocessor.
The microprocessor allows the choice of 3 different operating modes (except for ‘Lite’ which only
has Mode 1). 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. Note:- The ‘Lite’ version only has one supply input.
8.2
Operating Mode Selection (Universal Hopper Lite – Mode 1 ONLY)
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 100ms 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, i.e., any further changes in the levels at IN1 and IN2 will be ignored.
See Table 4.
Refer to section 11.5 for recommendations for driving input signals on pins IN1, IN2 and IN3.

8.2.1
MODE 0 - DIRECT SWITCHING (NOT ‘LITE’)
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.
8.2.2
MODE 1 - 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 OV at power up, mode 1 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.

Universal Hopper Series Manual
8.2.3
TSP079.doc
Issue 3.1 – Feb 2006
MODE 2 - COIN COUNTING (NOT ‘LITE’)
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 register is incremented. When a 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.
Figure 5: Minimum Timings
A pulse is defined as a falling edge followed by a rising edge.
Pulse edges may be no closer than 5ms (see Figure 5). This is so that the processor has
adequate time to poll the IN3 pin and debounce. This represents a maximum pulse rate of
100Hz.
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 100ms and further processing time
prior to running the main program.
8.2.4
RESET FUNCTION (NOT ‘LITE’)
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.

TSP079.doc
Issue 3.1 – Feb 2006
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 (Not applicable to the ‘Lite’). 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 “SENSOR” indicator switches on.
8.4
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 the LED
“SECURITY” indicator will be switched off. The optical security feature operates identically in all
3 Modes.
Note: The security feature works the same on the Universal Hopper Lite but there is no output
pin to indicate to the host machine that there is a security issue.
8.5
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.
8.6
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 pre-set 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 again. The current is tested after 100ms
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 soft 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 over current 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.

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 6: Jumper positions for coins with holes (MKIII Only)
If a MKlll hopper is converted from one coin size to the other, the jumper position must also be
altered. This is achieved by removing the track guard, as described in 7.3, placing the jumper in
the required positions, then refitting the track guard.

High Security Exit Window (Available for MK4 EMC version ONLY)
The high security version of the exit window has been designed to be retro-fittable into existing
MK4 EMC hoppers. Hence, high security hoppers will use the same main control board as the
existing EMC product and will retain the same operating modes.
The high security function will detect any attempts to “blind” the optical sensors by shining an
external light onto them. Such an action could cause the hopper to miscount.
The detection procedure, during normal operation – stationary or paying out – is:i).
ii).
iii).
iv).
The infra-red LED’s will be turned off for a fixed time, Toff;
At the end of the time period, the state of the phototransistors will be examined;
If the phototransistors are in the correct state, i.e. not seeing any light, the LED’s will
be turned on again;
After a defined time, Tint, the test will be repeated.
The detection sequence, in the case of a fault – stationary or paying out – is:i).
ii).
iii).
iv).
v).
The infra-red LED’s will be turned off for a fixed time, Toff;
At the end of the time period, the state of the phototransistors will be examined;
If the phototransistors are switched on, i.e. still seeing light, the LEDs will be left off
and also the phototransistors will be disconnected for a defined time, Tfault. This time
must be greater than 1 second;
When the phototransistors have been disconnected for 1 second, the main control
board will recognise the condition as a blocked opto. The hopper motor will be stopped
and the security output will be turned off. This will alert the host machine to the
problem;
At the end of the time period, Tfault, the optos will be turned on again and testing will
resume.
It is the responsibility of the host machine to monitor the security signal and to take whatever
action is deemed appropriate. All other functions of the hopper, i.e. motor control, jam clearing,
coin counting, etc, are the same as the existing product.
NOTE: During the 1 second period, between the fault being detected and the motor stopping, it
is possible that a few coins may be paid out and not counted.

OPTO TEST
By holding the hopper in reset and toggling the IN3 line, the optics can be checked for a
blockage prior to paying out.
During Reset, a High on IN3 will cause a low on “Output 1” and “Output 2”. Alternately a Low
on IN3 will cause a high on “Output 1” and “Output 2”.
NOTE:- This is only true if the optics are NOT blocked.

Electrical Specification Power Supply Requirements
9.1
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
(Opto and Security) are noise free.
9.1.1
SUGGESTED CONNECTION
A suggested connection diagram is shown in Figure 7.
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 1K and 4K7 resistors can be omitted.
Figure 7: Recommended Connection Diagram
9.1.2
EMC
The MKlll hopper is EMC hardened. There is a version of the 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)
ii)
iii)
Max cable length = 3 metres
All wires to the hopper should be bundled together.
Minimum capacitance between the logic supply rails = 100µF

11. Applications
11.1 Output Sensor Interfacing
Both sensor outputs are open collector NPN transistors, as shown in Figure 8.
When a coin is paid out, the raw sensor output will switch on, connecting output Pin 11 (Not
connected on the ‘Lite’ version) to OV, the Sensor output on Pin 3 will switch on approximately
5ms later - see Figure 9. 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 Figure 10.
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).
Figure 8: Sensor Output Cct.
Figure 9: Sensor Output Waveforms.
11.2 Motor Switch Off Time
When using the hopper in mode 0 (see section 8.2.1) 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 30ms of the leading
edge of the output. Similarly, to avoid erroneous payout in mode 1, IN3 should be taken high
within 30ms of the leading edge of the opto SENSOR output (pin 3).

11.3 Security Output (Not ‘Lite’)
The security output is an open collector NPN transistor which should be connected as shown
in Figure 8. In normal operation the transistor will be switched on, i.e. the output pin will be
connected to 0V. The transistor will switch off if a fault is detected – see section 8.4.
Figure 10: Recommended Security Output Sensor Interfaces.
11.4 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 11. The signal levels on these pins will be determined by the presence or absence
of an electrical contact, via the coins, between the 0 volt plate and the other plates.
Note:- High Level is not available with the Universal Hopper Lite.
Figure 11: Recommended Level Sense Plate Interfaces.
Tip:- When the hopper motor is running, coins will be moving across the level plates. This could
cause incorrect level signals. It is recommended that the level sense outputs are read when the
hopper motor is switched off.

11.5 IN1 to IN3 and Motor Control Inputs
These are the control signals from the host to the hopper which determine the Mode of
operation. These are input to the hopper microprocessor via a resistor as shown in Figure 12.
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 Figure 12) or if no change of mode
is required, then strapped to logic OV or left floating (internal pull-up) depending on the mode
required.
Figure 12: Recommended INx and Motor Control Inputs.
11.6 LED Indicators (Not ‘Lite’)
Three LED indicators are fitted on the hopper. On MKll and MKlll hoppers they are visible under
the track guard at the top corner, at the side of the coin exit. MK4 hoppers have the LED’s
mounted in the coin exit area.
See Figure 6 for details. The LED designations/positions are the same for all universal hoppers.

12. Technical Specifications
12.1 Coin Sizes
Please refer to Table 2.
The MK4 hopper however has extended this range to include 31mm diameter coins. Coins
falling outside of the above ranges may be used but would require special qualification.
For more information contact Money Controls Technical Services Department.
12.2 Capacity
Approximate, (±10%), coin capacities can be estimated by applying the following formula.
Alternatively a calculator program can be obtained from the Money Controls Technical Services
Department.

12.8 Important Supply Notes
1.
2.
3.
4.
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 pre-set 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 1.
