PRODUCT OPERATION

GENERAL

ELECTRO-MECHANICAL PRODUCT

When a coin is entered through the electro-mechanical changegiver there are several conditions that are electronically checked.

After coins have been accepted and a product selection button is pressed a sense current flows through the changegivers sense circuit. The sense current is not sufficient to energise the relay, but enough for the changegiver to detect. When the changegiver detects that a product selection button has been pressed the changegiver looks up the price associated with the selection. If sufficient credit exists the changegiver turns the price line output on. This disconnects the safety line from price line common and connects the price line output to price line common. The vend motor relay within the vending machine is then energised, turning the vend motor on and closing a switch across the selection button.

When the vend cycle begins the blocker signal indicates to the changegiver that a vend has started. The price of the vend is deducted and the changegiver waits for the vend to finish. The price line output is turned off when the changegiver considers the vend to have finished.

Unused credit may be returned after the vend has finished either automatically if in single vend mode, or by customer demand if it is in multi vend mode, or after a pre-determined time in multi-vend option setting, depending on how the changegiver has been set up.

SERIAL INTERFACE PRODUCTS

Dependent on which version of product is being used , when coins or cashless card are inserted the value involved will be shown on the display, if used. The host machine’s VMC communicates all functions as required with the changegiver and any other peripherals, such as an audit unit or cashless payment system, that are being used.

The VMC in the host machine produces signals to the changegiver (excluding MDB product) indicating when a vend is to be made, and the value of the vend required. The changegiver will then ascertain if sufficient credit is available to cover the cost of the vend. If the changegiver is set to “No Overpay” it will confirm that any remaining coin credit that would result from the vend can be returned before authorising the vend.

©, Mars, Inc., 1996. 5

CashFlow 560 changegiver Applications Design Guide

If the vend is allowed the cost will be deducted from the credit prior to authorising the VMC to start the vend. Should the vend fail, this credit will be re-instated.

ACCEPTOR MODULE

There are some functions of the acceptor module which are common across the whole CashFlow

include coin discrimination, control and communication. When a coin is put through the acceptor module it’s validity is

determined by measuring certain parameters. It also looks at the coin type status to define whether the payment is a valid coin or token, or an invalid coin. Finally, the inhibit status is checked. If the coin is not inhibited, then it will be accepted, the accept gate opened, and the coin routed to either a tube or cashbox. The acceptor module is made up of the discriminator, back cover and the accept gate.

The discriminator comprises a flight deck and lid which together form the coin control and flight path. On the inside of the flight deck lid there is a mechanical device incorporated near the coin entry point. This device is known as the coin deflector and is used to bring coins under control as they enter the product

A hinge at the top right hand side of the flight deck allows coupling of the lid via an intermediate component, known as the lid arm. This allows the lid to locate accurately to the flight deck independently of the hinge. The lid also maintains a parallel coin throat by being

spaced from the deck on three bosses which locate the lid squarely to the deck.

The design of the lid arm hinge area allows the lid to open to 180 degrees relative to the deck. The opening is restricted to just over 100 degrees by the back cover to prevent the lid possibly fouling other parts.

The action of the hinge spring allows the lid to remain open when past about 100 deg. and will snap shut when closed to about 60 degrees although the lid will need to be pressed to ensure that it is correctly seated against the deck. The acceptor module connects to the control board via a 10 way ribbon cable.

On the front of the acceptor module there is a six way socket. This is for use with a Mars

hand held and, when connected to the acceptor, allows some of the operational aspects of the changegiver to be altered.

ACCEPT GATE MODULE

The accept gate module contains a solenoid operated gate, optical coin strobes and coin routing components. Coins that are correctly discriminated are routed to the accept exit by energising the accept gate. Coins that are rejected are routed to the reject exit.

SEPARATOR

The separator separates the coins into different routes, either to the coin storage tubes or the cashbox. It contains a solenoid bank and, at the bottom, a top level sensor assembly which is used to avoid tube overflow.

CONTROL BOARD

This is the main PCB which controls the way in which the changegiver operates. There are several different control boards, but basically these are the 4 price for electromechanical machines, and the Executive, MDB and BDV for electronic machines.

SPINE

The spine provides the housing for all of the other modules. On the rear of the spine are the three standard keyhole fixing points for fitting the changegiver into a machine.

CashFlow 560 changegiver Applications Design Guide

TRANSFORMER ASSEMBLY

The transformer assembly is housed behind the keypad cover. To gain access to the transformer there is a screw located under the top flap of the keypad cover. Once this screw has been removed the keypad cover will lift off and the transformer is accessible. The transformer connects to the control board via two looms and is available in 24V, 100V, 120V, 220V, and 240V options.



Note: On CashFlow transformer is replaced by a reservoir capacitor.

KEYPAD

The keypad is used to float or dispense coins and to re-configure some aspects of the way in which the changegiver works.

DISPENSER

The dispenser is held in the spine by two clips, one on each side. It connects to the control board via a loom. It contains four dispense arms which, when operational, dispense coins from each of the four storage tubes. The dispenser also contains low level sensors which detect when the coin tubes are low on coins. It is possible to dispense coins from more than one tube at the same time.

560 BDV and MDB changegivers the

COIN STORAGE CASSETTE

The coin storage cassette clips to the front of the changegiver and contains four independent coin storage tubes. There are thirteen different sizes of tube, each numbered from 0 - 7. These cover most sizes of coins that you should want to route to coin tubes.

N.B. Some have a suffix of “.5” (i.e. 2.5), and dimensions range from 0 which has the largest bore and 7 with the smallest bore. Each tube has a designator fitted at the bottom. The size of the designator fitted is dependant upon the thickness of the coin. There are eight different sizes of designator each lettered from A - H.

The front cover is marked A,B,C,D to indicate the position of the fitted tube, as shown below. Coins of the following sizes can fit into each of the positions:

• Coin diameters from 15.0 to 26.0 mm in position A

• Coin diameters from 18.6 to 32.5 mm in position B

• Coin diameters from 15.0 to 29.2 mm in position C

• Coin diameters from 18.6 to 29.2 mm in position D

Although there are different sizes of tubes and designators available, not every tube can be fitted into every position in the cassette.

There are prisms located at the top of each tube which, when combined with the optos on the separator form the top level sensor. The top level sensors are used to indicate when a tube is full. When a tube is full any further coins are routed to the cashbox.

The cassette can be automatically filled by feeding coins through the product, or manually filled by removing the cassette from the changegiver.

On the front of the cassette are float indicators which you can position manually by sliding up and down.

Exact Change Equation

When the changegiver, other than MDB product, detects that the quantity of coins in a coin tube is below the low-level sensor, a signal is sent to the vending machine to switch on the exact change light (ECL) so as not to risk short-changing a customer.

Setting the exact change equation ensures that the optimum combinations of change coins are always dispensed, by using coins from alternative tubes to make up the change required, and that the ECL is on for the minimum time possible.

An explanation of the process used to determine the optimum coins for change can be found later under the heading of Best Change Calculation.

Two exact change equations can be set using Route Alpha 250 terminal, addresses 236 and 237. The tubes A, B, C and D are coded 1, 2, 4 and 8

Address 236 = exact change equation, part 1 - offers the ﬁrst option to use change coins from nominated tubes .

10 ©, Mars, Inc., 1996.

CashFlow 560 changegiver Applications Design Guide

Address 237 = exact change equation, part 2 - sets a second selection of change tubes.

Address 383 can also be used, with BDV product only, to give an additional early warning setting, (in conjunction with addresses 271-274), and trigger the ECL to come on at an earlier point when the coin count in a selected tube becomes low coded 1, 2, 4, and 8.

Low-level sensor

Tube

AB D 12 48Code

EXAMPLE: A four-tube changegiver contains 1p, 2p, 5p and 10p coins, and the vend price is 16p.

If 20p is inserted, the optimum change payout will be from tubes A and B. Therefore address 236 - exact change equation, part 1must be set to 3 (using code 1 + code 2 to equal 3). This setting will ensure that the ECL comes on when tubes A and B become low.

If 50p is inserted, the optimum change payout will be from tubes A, B AND D. Thus address 237 - exact change, equation part 2- must be set to 11( using codes 1 + 2 + 8 to equal 11. This setting will ensure that the ECL comes on when tubes A, B and C become low. Setting both addresses 236 and 237 will cause the ECL to come on when tubes A and B, or tubes A, B and C become low.

If the vending machine becomes inhibited (blocked) this is signalled to the changegiver by the blocker signal. During the inhibited state, coin acceptance is disabled. This condition may occur because there are no products left in the machine, or the machine has developed a fault.

©, Mars, Inc., 1996. 11

CashFlow 560 changegiver Applications Design Guide

Using Exact Change Inhibit

When the machine is in exact change mode, selected coins can be inhibited, other than with MDB product.

Setting the exact change inhibit option will stop a speciﬁed coin or coins being accepted when the exact change light is on. It is usual to inhibit the highest value coin(s) to minimise the risk of the customer being short-changed.

When the coin level rises again above the low count, the ECL is turned off, and the inhibit option switched off so that the previously inhibited coins are accepted.

The coin set for the unit is divided into three exact change groups, in which each coin has a code. The groups are associated with addresses 232, 233 or 234. Set the range value of the addresses to the code of the coin you want to inhibit. Add the codes together to inhibit more than one coin at a time in each group.

Addresses 232 - coins 1 - 4 using codes 1, 2, 4 and 8 Addresses 233 - coins 5 - 8 using codes 1, 2, 4 and 8 Addresses 234 - coins 9 - 12 using codes 1, 2, 4 and 8

CashFlow 560 changegiver Applications Design Guide

COIN ACCEPTANCE, ROUTING & RETURN

The changegiver has a standard coin entry and exit chuting. Coin return via a reject lever is also standard. The coin acceptance, and the routing used on coin acceptance, are dependant on:

• The set up of various configuration items in the changegiver EEPROM

• Other changegiver conditions which will alter while the changegiver is in operation

As a result of this, both coin acceptance and coin routing are dynamic, i.e. changing in time as the state of the changegiver alters. The dependencies are detailed in the following sections.

COIN ACCEPTANCE

The acceptance of each coin is determined primarily by the set up of default inhibits in the EEPROM. This specifies which coins should always be inhibited (i.e. rejected). In addition to these defaults, extra inhibits will be imposed depending on the following conditions:

In normal mode with the overpay inhibit flag set:

• Coins which are not dynamically routed to the tubes will be inhibited and rejected if their value, plus the existing coin credit, cannot be returned due to lack of correct change coins

• Coins which would take the total system credit over the maximum allowed credit are inhibited

• Vend tokens are inhibited if the total system credit is not zero

In normal mode with the overpay inhibit flag clear:

The Vending Machine Contoller (VMC) overules this in the MDB product

• If use exact change has been signalled, the exact change inhibits are imposed

• Coins which would take the total system credit over the maximum allowed credit are inhibited

• Vend tokens are inhibited if the total system credit is not zero

In float mode:

• All coins which are not dynamically routed to the tubes will be inhibited

In price teach mode:

• Coins which would take the total system credit over the maximum allowed credit are inhibited

• Vend tokens are inhibited

©, Mars, Inc., 1996. 13

CashFlow 560 changegiver Applications Design Guide

Global Coin Inhibit

In addition to the individual coin inhibits described above, a global coin inhibit can be imposed. This will inhibit all coin acceptance regardless of any other conditions. A global inhibit is imposed when:

• Manually dispensing coins either from the key pad or

the terminal

• Returning credit

• A vend is in progress (VMC function on MDB)

• A price is on the display due to a product selection

being made with insufficient credit. (When in price display mode). (Not on MDB)

• Value of tube contents is on the display. (Not MDB)

• Any bits in the EEPROM error register are set, apart

from code 5

• A free vend token has been accepted

• An executive type vending machine has indicated that

it requires a free vend

• The host machine has indicated it is inhibited

• The cashbox error code or if the protocol A error code

is set

• The blocker signal is not present

COIN ROUTING

The coin routing used is determined in the EEPROM. If a tube is not

fitted this is indicated as 00 on the Mars display. In addition, there are conditions which prevent coin routing to a tube even when it does store the coin. These are any of the following:

• The tube full sensor reads covered (or has failed its

self-test, if test enabled on acceptor)

• There was a fatal dispenser error on that tube

• The tube counts held in changegiver RAM are equal

to, or greater than, the maximum level for that tube.

The routes, determined by all the above criteria, are the dynamic routes. Before a coin can be routed it must first be accepted. If a coin is rejected none of the above applies.

CashFlow 560 changegiver Applications Design Guide

CHANGE PAYBACK

In general the changegiver will attempt to return any coin credit to the consumer, in the best possible coin mix. However, this simple statement requires clarification.

Use of Tubes

• The changegiver will only attempt to use tubes which are shown as fitted, and have not been disabled by the occurrence of sensor or dispenser faults

• If a tube is fitted and is not disabled, it will be allowed to be used for change payback only if its tube counts are above the safe count value at the start of the change payback sequence

• The changegiver will not function if the coin storage cassette is not fitted

Once the tubes that can be used have been determined the best coin mix to pay back the change is calculated. Best coin mix is defined as the first of the following found to be possible:

• Correct change paid with minimum number of coins

• Correct change paid with non-optimal coin mix

• Closest change paid with minimum number of coins

• Closest change paid with non-optimal coin mix

• No change paid

Once the best coin mix has been determined the dispensers will start to pay the change out. The software will drive as many motors as possible at once to expedite the change payback. (Not MDB)

Should either of the following occur the dispense sequence will be suspended once each motor has got to its home position:

• The tube has run out of coins while coins are still required. This could occur if the low level sensor/s go from covered to uncovered, causing a tube count recalibration, which reduced the number of coins held in the tube. (Not MDB)

• A dispenser error is detected (stall, etc.)

The software will then re-compute the best coin mix to pay back the credit still remaining and re-start the dispensers with this new coin mix. The above will be repeated until all the change which can be dispensed has been paid.

TUBE SENSOR USAGE

This section describes the operation of the tube sensors in more detail. The sensor operation significantly affects the users perception of how the changegiver appears to operate.

Each tube has associated with it three sensors:

• The full level sensor (opto sensor)

• The low level sensor (opto sensor)

• The tube dispenser home position sensor (reed switch)

Full sensors Effect on coin routing

The changegiver cannot read the tube full sensors directly, but must request their status from the acceptor module. The acceptor module then performs a self-test of the full sensors. The acceptor module reports both the reading of the sensor, covered or uncovered, and the outcome of the self-test, OK or failed.

The changegiver will perform the following actions, on a tube-bytube basis, based on the self-test results and the sensor reading:

Self-Test

Result

OK Un-covered

OK Covered

Sensor

Reading

Changegiver Action

This is the normally expected result. The changegiver will clear a full sensor error, if ﬂagged. It does not take any further direct action. However the routes may be updated if the tube counts have got to their maximum level

This is a fault condition, as the maximum level a tube should reach is 3 coins from full. The changegiver will signal a full level sensor error. If the low level sensor is reading covered then there is a good chance that the tube is really full, so the changegiver will recalibrate the tube counts to the pre-programmed Full Number.

Self-Test

Sensor

Changegiver Action

This condition cannot occur, as the acceptor will always assume any

Failed Un-covered

Failed Covered

failed sensors are covered, and will act as if this is so.

This is a fault condition, due to the failure of the acceptor module’s sensor self-test (opto was seen on with the LED being off). The changegiver will signal a full level sensor error. It will ignore the reported reading, and continue to use the last (good) reading before the failure. The routing will be updated. The tube is still used for dispense. If all 4 main tube sensors are reported as failed, then the cassette is assume to be removed, and a cassette out error will be ﬂagged. Note that sunlight, or other intense light source can affect the sensor self-test, causing it to fail. Thus the changegiver will inhibit the self-test feature when ﬂoat or price teach mode is entered. When this mode of operation is selected, the selftest result will always be OK.

Coin cassette removal detection

If the coin storage cassette is removed, all the tube full sensors on the tubes will read covered. Should the changegiver detect this all tubes full condition, it will flag a cassette removed error and will indicate a changegiver error on the error LED. No change payback will be attempted from the tubes. Manual dispensing from the tubes will still be allowed, but the tube counts will not be decremented. Coins will still be accepted but routed to the cashbox.

The error will be cleared as soon as a coin is accepted or a dispense

CashFlow 560 changegiver Applications Design Guide

attempted with the coin cassette back in place. Note that if all tubes really have overfilled to cover the sensors then a cassette removed error will be indicated, but will clear once the tube level drops.

Full sensor error detection

The changegiver will detect full sensor errors on dispensing from a tube if coin storage cassette removal has not been detected. The appropriate full sensor error register will be set and a changegiver error will be indicated on the error LED. Since the sensor reads full the tube will no longer be routed to, but no other action will be taken, i.e. the tube will still be dispensed from.

The full sensors are read on initialisation, acceptance and dispensing coins. Full sensor errors relating to a tube are cleared whenever a full sensor reads uncovered. Note that this means that if more than 1 coin covers the full sensor, the full error for that tube will initially be set on dispensing from that tube, but it will be cleared again as soon as the sensor becomes uncovered.

Coin count re-calibration

When accepting coins, the full sensors will be used for re-calibrating the number of coins in the tubes. For any given coin type the number of coins that it takes to cover the full sensor can vary due to variations in coin thickness. For this reason the tube counts for a tube will be set to be their full re-calibration number only if:

• The sensor status has changed

• The result of the sensor self test was good

• A coin cassette error has not been detected

• The recorded tube counts are more than 9 from their expected level:

Low sensor error detection

The low sensor is checked at the following times:

• On power-up

• Before beginning any dispensing, either manual dispensing or credit return

• Immediately after every coin is paid out

• One second after a coin is accepted

The status of the low level sensors will be held in non-volatile memory, thus preserving this information for the next power-up.

CashFlow 560 changegiver Applications Design Guide

Coin count re-calibration

Low level recalibration is intelligent in its handling of tube storage cassette removal and replacement. The main assumption made is that the tube storage cassette is not removed during a change return operation. The following table gives the details of the low sensor operation.

A tolerance of +/-one coin is applied to the tube counts before recalibration on low level sensors is done. This reflects the fact that due to the variables, both electrical and mechanical, it is unlikely that the number of coins in a tube will always be the same.

Thus, if the tube counts are within one of their expected level , no recalibration will occur when the low sensor goes from covered to uncovered.

Home sensors

The function of the home sensors is to signal that the dispenser arms are in the correct parked position before an attempt to dispense coins from the coin storage cassette is made. Should this fault have occured then an error signal will appear on the (red) error LED on the keypad, which will flash on and off.

To remedy this the coin storage cassette should be removed and then pressing the (yellow) mode key twice. This will drive the dispense arm solenoids and and all 4 of the dispense arms will be parked in the correct position in sequence.

ELECTRO MECHANICAL INTERFACE

All electro-mechanical interface connections between the changegiver and the host vending machine are electrically isolated. Outputs are isolated via the relays (i.e. price line outputs) and the inputs from the machine are current limited and optically isolated. The standard electro-mechanical interface parameters for all changegivers defined in this specification are as follows:

EXACT CHANGE OUTPUT

(Switched neutral). Rated 0.5 Amps AC resistive load. Fused 1.6 Amps thermal. Fault rating 3.5 Amps. When the changegiver detects the change available in the tubes is low it indicates exact change to the vending machine. The machine normally uses this signal to illuminate a lamp informing the customer to use the correct money.

CREDIT RELAY DRIVE

(Switched Ground). Open collector drive provided (includes flyback diode) - 20mA @12V. The credit relay is only available on the 4 price changegiver as an option located outside the unit.

SAFETY LINE

(Switched Price Line Common). Rated 2.6 Amps. Fused (via price line common) 3.15 Amps fast. Fault rating 7.0 Amps. This output is normally connected to price line common via all the price line relays (in their off state). When any price line becomes active the safety line becomes open circuit within the changegiver.

PRICE LINE COMMON

(Normally connected to Line). Rated 2.6 Amps AC inductive load. Fused 3.15 Amps fast. Fault rating 7.0 Amps.

PRICE LINE OUTPUTS

Rated 2.6 Amps AC inductive load (worst case power factor of 0.5). Fused (via Price Line Common) 3.15 Amps fast. Fault rating 7.0 Amps. A sense input will be seen when >1.5mA is flowing through the sense input. When a sense input becomes active the changegiver determines the price to be charged for the selection requested. If sufficient credit exists it will energise the appropriate price line relay. This relay will disconnect Safety from price line common and connect price line common to the selected price line output enabling the vending machine to proceed with the vend cycle.

CashFlow 560 changegiver Applications Design Guide

MACHINE INTERFACE

The normal idle state of the Electro-mechanical / 4 Price machine interface with no credit is as follows:

• Blocker input active (connected to LINE)

• EA input (if present) - inactive

• Sense input lines inactive (open circuit)

• Safety Line output connected to price line common (via ALL price line relays)

• Price line outputs inactive (open circuit)

The 4 price changegiver has 4 input/output lines, providing for 4 sense inputs, and 4 price line outputs. When a product selection is detected the appropriate price line output is enabled (if sufficient credit exists). As the price line relay outputs are interlocked, enabling one price line output ensures that the other price line outputs are disabled. When the reset condition is detected the price relay is turned off.

CashFlow 560 changegiver Applications Design Guide

SINGLE / MULTI VEND

Unused credit (change) is returned to the customer either automatically or on demand by pressing the reject lever. If the changegiver is set to single vend mode any unused credit is returned automatically immediately after the vend finished condition is met. In multi vend mode the credit balance is not returned until requested by the customer (or automatically after a selectable timeout period has elapsed).

SENSE INPUT TIMING

During the period between pressing the product selection button and the price line output becoming active the changegiver must determine the price line of the selection, look-up the vend price and decide whether to allow the vend, and if so energise the price line relay. If the sense input from the vending machine is A.C. the sense current is only detected during the positive half cycle, therefore it may be 1/2 cycle (i.e. 10mS) before the sense input is detected, leaving 25mS for everything else.

Note: Price line output becomes active only after the sense input is active and the changegiver has authorised the vend. (i.e. credit > vend price)

Price Line Output Timing

When a price line output has been energised the changegiver will wait for the vend start signal. This is indicated by the blocker input becoming inactive. If the vend start signal is not seen within 2.5 +/-

Vend Start Timing

VEND FINISHED

valid vend start)

While the vend is in progress the vending machine holds the blocker signal inactive. When the vend is finished the blocker signal returns to its normal active state. As far as the changegiver is concerned the vend is considered to have finished when the reset conditions are met, and the price line output is disabled. The changegiver can be programmed to several different reset conditions to suit different vending machine interfaces:

• Blocker reset

• Delayed blocker reset

• Blocker hold reset

• Escrow accept reset

If the reset conditions are not met (i.e. the vend failed), the vend price will be paid back to the customers credit balance.

BLOCKER RESET

The changegiver assumes the vend has finished successfully as soon as the vend start signal is received (blocker signal is seen to be inactive). The price line output is turned off at this point, with no added delay. This is typically <30 mS.

28 ©, Mars, Inc., 1996.

CashFlow 560 changegiver Applications Design Guide

DELAYED BLOCKER RESET

Blocker reset is the most commonly used reset condition In this reset mode the price line output remains active for either 30

mS (most commonly used) or 200 +/- 10 mS after the vend start signal is detected (blocker signal removed). The vend is assumed to have finished successfully after this delay and the price line output is turned off. The product may be in either 30mS or 200mS mode.

The delay is required to ensure the price line output is active for sufficient time for some machines to latch the signal.

ESCROW ACCEPT

In this mode the escrow accept (EA) input is used in conjunction with the blocker input to indicate a successful completion of a vend cycle. Normally, blocker removal signals the vend has started. The end of the vend is indicated when EA becomes active while blocker is still inactive. If the blocker signal returns to its active state before EA is active the vend is deemed to have failed, the price output is deactivated and price of the vend is added back to the credit so that the customer can try again or have his money back.

To allow for any fault condition the changegiver will only wait 1 minute (+/- 2 seconds) for the EA reset condition to be met. If this does not occur the vend is assumed to have failed and is dealt with in the same way as for blocker hold reset.

EXTERNAL CREDIT DISPLAY

For electro-mechanical interface applications the external display, if fitted, can provide the following information:

• Current credit in real money (Consumer)

• Vend price in real money, used in price display mode(Consumer)

• Accumulated credit in price teach & float modes (Operator / Route person)

• Power-on indicator (Service engineer)

• Value of cash in tubes (Operator / Route Person)

DISPLAYING CREDIT

If there is credit in the system, either coin or value token, then the total value of this credit will be displayed. The display will be in real money units. Any leading zeros will be blanked. The decimal point will be lit according to the decimal point setting in the EEPROM. A decimal point setting of 0 indicates zero places of decimal, i.e. the decimal point is lit on the right hand digit. A decimal point setting of 1 indicates one place of decimal, and so on. Any value of decimal point over 4 will be ignored and no decimal point will be lit.

If there is free vend credit available, either by free vend token or host machine free vend, the credit display will indicate this by a display of 5 dashes on the middle segments.

If there is no credit in the system, the display will show a single 0 in the right hand digit. No decimal point will be lit.

CANCELLING CREDIT

If you have been testing or resetting the changegiver outside of a shifted mode you may accumulate credit in real money terms. To cancel any credit, press the mode key once followed by the A key twice.

©, Mars, Inc., 1996. 33

CashFlow 560 changegiver Applications Design Guide

DISPLAYING VEND PRICE

If price display is enabled, and you make a selection whose value is less than the current system credit, then the display will show the price of the vend, in real money, while the selection is active. Leading zero blanking and decimal point will be handled as the display of credit.

DISPLAYING PRICE TEACH CREDIT

If the changegiver is in price teach mode, the current value of credit will be displayed in real money values. Leading zero blanking and the flashing decimal point will be handled as the display of credit.

DISPLAYING FLOAT VALUE

If the changegiver is in automatic float mode, the total value of any coins accepted as float will be displayed in real money values. Leading zero blanking and the flashing decimal point will be handled as the display of credit. This value is removed when the changegiver returns to normal operation.

POWER ON INDICATOR

On system power-up or reset, the changegiver will light all segments of the display for 0.5 seconds. If there is no host or changegiver fault present, the red LED will light. This will provide you with a basic check of the display and associated H/W.

DISPLAYING TUBE VALUE

A display of the value of coins the changegiver thinks are contained in the tubes can be obtained by pressing the mode key twice with the tube cassette fitted. The tube contents value will be displayed for 2 seconds on the display.

Note that the calculation is based on tube counts, and on the value of the first coin type in the tube.

MAN MACHINE INTERFACES

KEYPAD

All changegivers have a keypad mounted on the front face. Two LEDs are also mounted in this area to indicate the operational state of the changegiver. The keypad will enable the following functions to be performed:

• Dispense coins

• Set price(s). See Note below.

• Float the changegiver

• Reset tube counts

• Home the dispensers

• Display the value of coins in the tubes

NOTE: Setting Prices is available at all times with electromechanical product, unless Route Alpha terminal address 245 has been set to inhibit.

With BDV and Executive product it will apply only when Route Alpha 250 terminal address 238 has been activated.

Setting Prices function is not available for MDB product.

The keypad has four letter keys and a mode key. The mode key allows shifted functions to be associated with each of the letter keys. Two LEDs provide simple diagnostic information and will assist the use of the keypad. The diagram below shows the layout of the keypad and its associated labeling. The following sections describe its operation.

Yellow LED

Red LED

MODE key (yellow)

Keypad & Keypad Label

36 ©, Mars, Inc., 1996.

CashFlow 560 changegiver Applications Design Guide

LED Usage

The top (yellow) LED is used to indicate whether the keypad is in normal or shifted mode. If the LED is off, the keypad mode is in normal mode. When the mode key is pressed, the yellow LED will start to flash at 2 Hz (± 1%) to indicate that the shifted functions defined by the icons on the keys, are accessible. Note that the mode key does not need to be held down to access the shifted functions.

If no further key is pressed within 10 seconds, or the mode key is pressed a second time, the keypad will return to its normal mode. The yellow LED will go off, and the shifted functions will be disabled. If a letter key is pressed within 10 seconds, then the changegiver will turn the yellow LED on continually, and attempt to perform the required action. See the following sections for details of the shifted functions.

The bottom (red) LED is used to indicate the fault status of the system. If there are no errors, the LED will be illuminated continually. If a changegiver error is detected, then the red LED will flash at 2Hz (± 1%). If a fault is detected on the host machine, then the red LED will be turned off. Machine faults will take precedence over changegiver faults.

If the state of the system requires that both LEDs flash, then they will be synchronized to each other in anti-phase (i.e. yellow on - red off, yellow off - red on).

Manual Coin Dispense

If the changegiver is idle (i.e. not vending or accepting coins), the user can manually dispense coins from the 4 tubes by simply pressing the relevant letter key. On a single press-and-release of a letter key, the changegiver will attempt to pay a single coin from the requested tube.

If you wish to get more than 1 coin from the tube, you can continue to hold the key down. This will cause the changegiver to start dispensing further coins at the rate of 1 coin every 0.5 seconds (subject to the dispenser cycle time being less than this).

If you release the key within 3 seconds of the initial press, then dispensing will stop after the current coin is dispensed. Multiple dispensing is not allowed on empty tubes (tube counts = 0).

If the key is held for more than 3 seconds, dispensing will latch, and release of the key will have no effect. The dispenser will continue to dispense a coin every 0.3 seconds (subject to the dispenser cycle

©, Mars, Inc., 1996. 37

CashFlow 560 changegiver Applications Design Guide

time being less than this) until the tube counts reach their programmed safe count, or any key is pressed.

If 2, or more, letter keys are pressed at the same time, then the changegiver will pay coins from the selected tubes in the same manner as described above. Note that the 3 second latch time is measured from the time the last key is pressed, and dispensing will not unlatch until all the selected tubes reach their programmed safe count.

Automatic Tube Float (Float Up)

You can refill the tubes to their pre-programmed float level by the use of the float function. Float is only available if the changegiver is idle. To access float, press the mode key to get the shifted functions, and then press the key with the float icon (key A). Entering float mode will clear any accumulated credit, and will be indicated on the changegiver’s credit display by all decimal points being lit.

On entry to float, a longer time-out of 45 seconds will be started. You can then enter coins via the acceptor. The changegiver will automatically accept only the coins required to bring the tubes up to their programmed float level. On a tube reaching the required float level, any further coins of that type will be rejected. The value of any coins accepted as float will be accumulated, and displayed on the credit display (if fitted). This display value will be shown with the decimal point flashing.

During float the yellow LED will remain on, indicating that a shifted function is active. The changegiver will exit float mode, and turn off the yellow LED, if any of the following occur:

• No float coins accepted during a 45 second period

• The float key (A) is pressed

• The float down (C) key is pressed

• The reset tube counts key is pressed

Note that on exit of float, there is no need to press the mode key first, as the shifted functions are already active. When float mode is exited the changegiver will clear down the credit display, and resume normal coin acceptance.

If float mode is exited by either of the first two methods above, then the tube counts will not be modified further. If float mode is exit by pressing the reset tube counts key, then the tube counts will all be set to their pre-programmed float levels.

CashFlow 560 changegiver Applications Design Guide

Float Down Mode

When you wish to float down the tubes, simply press the mode key to get to the shifted functions, then press the A key to enter float mode, followed by the C key. At this point the changegiver will start to dispense coins until all tube counts reach the pre-programmed float levels. Note that if all counts were equal to or less than the float levels, then no dispense will occur.

Resetting Tube Counts

You can force the tube counts to be set to their pre-programmed values by use of the reset tube counts function. In order to avoid inadvertent resetting of tube counts, this function is only enabled if the changegiver is in float mode, and an IDTS audit FEM is not present.

If key B is pressed while the changegiver is in float mode, then all of the tube counts for the 4 main tubes will be set to their preprogrammed float levels. The changegiver will then exit float mode. If the actual number of coins in the tubes do not match these float levels, then the coin counts will be incorrect until recalibration occurs. If access to this function is attempted when the changegiver is not in float mode, i.e. pressing the mode key, then pressing the reset key, it will be ignored. The keypad will revert back to normal mode after 10 seconds and the yellow LED will then stop flashing.

Price Teach

Subject to the earlier note the prices held by the changegiver can be set using the price teach function. Price teach is only available if the changegiver is idle. To access price teach, press the mode key to get the shifted functions, then press the key with the price icon (key C). Entering price teach mode will clear any accumulated credit, and allow the user to clear credit, and will be indicated on the changegiver’s credit display by all decimal points being lit.

On entry to price teach, a longer time-out of 45 seconds will commence. You can then enter coins via the acceptor to the value required for the price to be set. Any coins entered will be accumulated as credit, and displayed on the credit display, if fitted. This display value will be shown with the decimal point flashing.

If there is accumulated credit, then any selection which becomes active will have its price set to the value of credit accumulated. If no credit was accumulated, then any selections made will not have their price modified. This is to prevent inadvertent zeroing of prices on permanent sense machines. Price teach only allows the setting of non-zero prices. Should you wish to clear a price to zero, then the Route Alpha 250 terminal must be used.

©, Mars, Inc., 1996. 39

CashFlow 560 changegiver Applications Design Guide

The sequence of inserting coins then making a selection can be repeated for all selections for which you wish to modify the price. Note that the main principle of price teach is that selections will have their price set to the current accumulated credit value, so that if a number of selections are required to be set to the same price, once the correct credit value is reached, all that needs to be done is to press the selection buttons.

During price teach the yellow LED will remain on, indicating that a shifted function is active. In addition, all keys except the price teach key will be ignored. The changegiver will exit price teach mode, and turn off the LED, if any of the following occur:

• No activity relating to price teach made during a 45 second period.

• The price teach key is pressed.

Note that on exiting price teach, there is no need to press the mode key first, as the shifted functions are already active. When price teach mode is exited the changegiver will attempt to return any accumulated credit to the user using the tube coins.

Note that on serial interface changegivers, the prices are not normally held in the changegiver and are thus inaccessible to this form of update, unless the price holding option is enabled via the support terminal.

Homing the Dispensers

You can home all the dispenser arms by first pressing the mode key to get the shifted functions, then pressing the mode key a second time. This will home each of the dispenser arms which are not seen to be at home, as read by the position sensors. This will only work if the tube cassette is removed.

Displaying Tube Value

You can easily get a display of the value of coins the changegiver thinks are contained in the tubes by pressing the mode key twice with the tube cassette fitted. This will cause the tube contents value to be displayed for 2 seconds on the changegiver’s credit display.

Note that only tubes which are set up as fitted will be included in this calculation. Note also the calculation is based on tube counts and on the value of the first coin type in the tube.

INTERNAL DIAGNOSTICS & ERROR HANDLING

The indication of an error being present either in the host or in the changegiver is given by the red LED. This section details various errors, and the action taken by the changegiver.

• Host machine problems

• Coin handling problems

• On-board EEPROM problems

• Audit FEM problems

• FIB communication errors

• Miscellaneous errors

HOST MACHINE PROBLEMS Host Inhibited

On both electro-mechanical and electronic hosts, an indication is provided to the changegiver if the host is inhibited (e.g. blocker inactive on electro-mechanical machines, no polling on MDB). The error handling for this condition is:

• Indicate host error on LED

• Disable all coin acceptance in normal mode

• Disable all coin acceptance in float mode

• Disable all coin acceptance in price teach mode

• Manual dispense is still allowed

• Route Alpha 250 terminal comms still allowed

• Changegiver will continually check if host is re-enabled

Removal of Blocker

The start of vend condition on electro-mechanical hosts is signalled by blocker becoming inactive after the price relay has been turned on. Normally there is a 2.5 second timeout on this, which will terminate the vend sequence with no loss of credit should blocker not go inactive. In blocker hold mode, due to the possibility of frauding certain machines, this timeout is not used. Therefore, if the start of the vend (as signalled by the removal of the blocker signal) does not occur, the following error state will result:

• Indicate host error on LED

• Inhibit all changegiver functions

• Changegiver will continually check if vend starts

©, Mars, Inc., 1996. 41

CashFlow 560 changegiver Applications Design Guide

Blocker Return

The end of vend condition on electro-mechanical hosts depends on the reset mode selected. In blocker hold mode, the end of vend is signalled by the return of the blocker signal. If this does not occur, the following error state will result:

• Indicate host error on LED

• Inhibit all changegiver functions

• Changegiver will continually check if host is re-enabled

Cashbox Full

An input is provided for a cashbox full sensor (provided by the host). The error handling for this sensor is:

• Indicate host error on LED

• Set cashbox full error flag (code 7 in error register)

• Disable all coin acceptance in normal mode

• Disable all coin acceptance in float mode

• Disable all coin acceptance in price teach mode

• Manual dispense is still allowed

• Terminal comms is still allowed

• Cashbox must be emptied to reset error

ON-BOARD EEPROM PROBLEMS Incorrect Conﬁguration vsn. No.

If the configuration file version number in the on-board EEPROM does not match the version expected in the software, the following error handling applies:

• Set code 4 of EEPROM error register

• Indicate changegiver error on LED

Route Alpha 250 terminal.

• No upload of EEPROM data will occur

• All coin acceptance will be disabled

• The keypad will be disabled, apart from the mode key

• Terminal comms. still allowed

• No save of data to EEPROM on power fail

44 ©, Mars, Inc., 1996.

CashFlow 560 changegiver Applications Design Guide

• The configuration version number must be corrected. The error will then be cleared on changegiver re-

EEPROM Corruption

If a corruption is detected in the EEPROM at upload time, the following error handling applies:

• Set code 0 - 1 of EEPROM error register

• Indicate changegiver error on LED

• No upload of EEPROM data will occur

• All coin acceptance will be disabled

• The keypad will be disabled, apart from the mode key

initialisation. This can be done by;

• Clearing the error flag,

• Updating the EEPROM version number,

• Re-initialising.

• Terminal comms is still allowed

• No save of data to EEPROM on power fail

While a reset device error appears to clear the error, note that there will be no configuration data uploaded into RAM, and hence the changegiver’s operation will be indeterminate. After clearing the error, the checksum of the affected page should be corrected and the changegiver re-initialised.

Write Timeout

If a timeout occurs when writing to theEEPROM, the following error handling applies:

• Set bit 7 of EEPROM error register

• Indicate changegiver error on LED

• All coin acceptance will be disabled

• The keypad will remain enabled, with manual dispense still allowed

• Terminal comms is still allowed

• No save of data to EEPROM on power fail

• Changegiver must be switched off to reset error.

VIA MARS ROUTE ALPHA 250 TERMINAL

With a Mars Route Alpha 250 terminal you can re-configure any of the functions available for a particular product. The terminal is connected to the acceptor via a six way connector which plugs into the front of the acceptor.



The terminal is used to check or change certain data which affects the way the changegiver operates. The data is held in addresses. Each address has a unique number which identifies the feature you wish to read or change e.g. if you want to change from single vend to multi vend then you need to go to address number 226 and put in a 1 (single vend is a 0).

The following pages will explain how to access and change the data in certain addresses. At the end of this section there is a list of addresses and the relevant values. Particular reference should be made to the symbols in this section which indicate the applications (i.e. electromechanical, Executive, BDV and MDB) for which each address is appropriate.

Reset Key: used to reset all modes and to initialise any settings that

you have changed. If the reset key is pressed while an address is being updated then the address may not be updated. The reset key must be pressed to store the changes that you have made.

Up Key: used to increase the value displayed on the screen. Down Key: used to decrease the value displayed on the screen. Left Key: used to scroll the display to the left when a large number

is being accessed that cannot be fully displayed on the screen.

RESET

DISPLAY

RIGHT

DOWN

Right Key: used to scroll the display to the right when a large

number is being accessed that cannot be fully displayed on the screen.

Enter Key: used to change between the address and data displays. Other Facilities of the Terminal

The terminal has several features to speed up its use. This includes the ability to scan at a higher speed with the keys auto repeating, to automatically roll over from its highest to lowest address and to inform the operator should a communication error occur. Should you need to know which version numbers of the software is used in the changegiver the UP key is pressed while the terminal is

in reset mode. The terminal will firstly display the acceptor HI address, if the UP key is pressed again the acceptor software version number will be displayed. Pressing the UP key again will display the acceptor eeprom number and if pressed again the acceptor configuration code. Pressing the RIGHT key will display the changegiver’s software number To return to normal operation press the RESET key.

CashFlow 560 changegiver Applications Design Guide

Auto Repeating Keys

If either the UP or DOWN keys are kept pressed they automatically repeat. The repeat speed of the key increases the longer the key is held down.

Double Click Hotkeying

If a key is doubled clicked (pressed twice in quick succession) then this causes the address number to increment by a larger amount. e.g. if the user starts at address number 1 then double clicks the UP key, the address will jump to 40, double click again the address will jump to address 100 etc. This is useful as the addresses used for the changegiver start at address 200. You can also double click the DOWN key to decrement by larger amounts.

USING THE TERMINAL

As soon as the terminal is connected to a changegiver it powers up and interrogates the product.

The terminal display will clear and briefly show a message that indicates the version of software in the terminal. A display of [0 1.0] means software with a version number of 1.0 is fitted in the terminal.

Power up message Software version = 1.0

After a few seconds the display will show the number [1.] or [1.-]. Not all configuration items are applicable to every product but all the address values are shown on the display. If the value for the address is applicable to the product a dash will be present at the far right position on the display. The value can then be accessed and changed if required.

No dash displayed Address is not accessible for this product

Dash is displayed Address is therefore accessible

50 ©, Mars, Inc., 1996.

CashFlow 560 changegiver Applications Design Guide

The basic operation to alter the information held in an address is:



1 Connect the terminal to the CashFlow

product. 2 Wait for the terminal to power up correctly. 3 Select the address by using the UP and DOWN keys. 4 Examine the data by pressing the ENTER key. 5 Alter the data value by pressing the UP or DOWN keys

until the new value has been reached. 6 Press the ENTER key to return to displaying addresses. 7 Press the RESET key to initialise the new value.

When the terminal is displaying values stored at addresses, no decimal point will be displayed.

If an error occurs with the communication between the terminal and the changegiver the display will show an error message of four half height zeroes.

Error message

This message will stay on the display. Pressing the RESET key may clear the fault. The display will then revert to showing the current address. If the error occurred while updating an address then the value of that address should be checked as it may not have been updated correctly. If, after pressing the RESET key, the fault remains the error message will stay and you need to return the terminal for repair.

As the screen is capable of only displaying four digits at any one time the number displayed on the screen can be scrolled if it is greater than 9999 by using the LEFT and RIGHT keys. The left or rightmost digit will flash indicating an extra digit can be examined by use of the scrolling keys e.g. Value is 12345

Function Expansion Module

Visual Audit can be obtained, from the electro-mechanical and Executive products only, when an audit function expansion module (FEM) is installed as an accessory on to the Control PCB.

Data can be viewed with the use of a Route Alpha 250 terminal and the process for using this method follows below. Data is also

available via a Mars through an interface loom from the changegiver, through a DEX/

UCS jack-plug connected to a Mars red optical interrogation point in the side of the machine, also using the MEQ terminal.

Visual Audit Interrogation

The Route Alpha 250 terminal display may not be able to show all details for each address. In order to ensure that all data has been read two quite separate addresses must be interrogated, one consisting of the least significant (ls) digits, and the other the most significant (ms) digits of the data.

To convert these two readings to a single audit value the (ms) value shown must be multiplied by 65536 and the (ls) figure added to the result.

The following process should be followed to use the Route Alpha 250 terminal for retrieval of data:

• Firstly select the required address using the Up and

DOWN keys.

• Press ENTER to display the contents of the address. If

the value exceeds four digits the LEFT and RIGHT

keys are used to scroll the display left or right.

EXAMPLE. (To read the Cash In Tubes value)

• Select address 900

• Press ENTER to display the (ls) value, (e.g 54919)

• Press ENTER to return to address mode

• Press UP to select address 901

• Press ENTER to display the (ms) value, (e.g. 18)

• Multiply (ms) value by 65536 (18 x 65536 = 1179648)

and add (ls) value. (1179648 + 54919 = 1234567)

NOTES All values are displayed on the terminal with no decimal point.

In order to reset the interim values address 999 must be used, ensuring that it is set to 9.

All values displayed will be in the range of 0 - 65535.

The relevant addresses for the Route Aplha 250 terminal in the following list are 900-999.

CashFlow 560 changegiver Applications Design Guide

Testing the Terminal

It is possible to test all the features of the terminal itself by putting the unit into a special test mode. To enter the test mode hold the ENTER key pressed when powering the unit up. The display will initially show three digits indicating the result of an automatic on board test. The display format is:

[<BUSY state> <DATA state> <AUTO TEST result>] where <BUSY state> = current state of BUSY line, 0 = low, 1 = high <DATA state> = current state of DATA line, 0 =low, 1=high <AUTO TEST result> = result of automatic test

0 = Pass

1 = BUSY line error

Pressing the ENTER key activates the next stage of test. The LCD is tested by displaying a pattern of four identical digits on

the display. The digits alter every 1/2 second and the display should be examined to check all the digits are formed correctly.

Display will show: [0000], [1111], [2222], [3333], [4444], [5555], [6666], [7777], [8888],

[9999], [----], [oooo], [ ], [....].

Pressing the ENTER key activates the next stage of test. The terminal keys are checked next. A single number is shown on

the display indicating what key was pressed last. Display shows:

2 = DATA line error

3 = BUSY and DATA line errors

[ 0] No key pressed

[ 1] UP key pressed

[ 2] RIGHT pressed

[ 3] DOWN key pressed

[ 4] LEFT key pressed

[ 5] ENTER key pressed

This is the last test and the RESET key must be pressed to restart the terminal in normal operational mode.

Vibration (through machine mounting)

INSTALLATION

To ensure that the changegiver operates correctly it must be mounted so that it hangs within side elevations.

The reject lever must have a minimum 3mm clearance from the machine reject mechanism when installed.

The amount of travel for the coin mechanism’s reject lever when engaged should normally be between 12-18mm. It should not be forced beyond this point as there is a danger of the reject lever bottoming out and damage being caused.

BS 2011: part 2.I Ed: 1977

Crush Neatly stacked units of the same type may

be stacked to a height of 2 metres.

LIQUIDS

Water

The units inclusive of PCBs will be splash protected. The coin entry encourages excess water towards the reject path

and the front of the product out of the coin path. Coin stall under these conditions is minimised.

The above should in no way be interpreted as a specification capable of operating at 100% RH.

Salt Water

As above. Prolonged exposure in a salt laden atmosphere will lead to PCB

corrosion damage.

Other Liquids

This includes: dilute carbonic acid, dilute citric acid, carbonated drinks, beer, tea, coffee, chocolate, soup, syrup, sugar residue and uric acid.

• Certain beverages and the dilute acids may cause sim-

ilar effects to salt water if they contact the PCB’s.

• Wet performance will be similar to that described for

water.

• Liquids which leave a residue on drying which affects

the passage of coins could cause malfunction.

CashFlow 560 changegiver Applications Design Guide

VOLTAGE

Supply

The unit will operate to specification on the following supply voltages:

46 - 64 Hz AC RMS.

• 20.4 - 26.4 V RMS

• 87 - 121 V RMS

• 95 - 132 V RMS

• 187 - 242 V RMS

• 212 - 264 V RMS

• 207 - 244 V RMS* single transformer profile

Note: For each of the above voltage waveforms the peak voltage must be √2 V RMS

DC (BDV)

Absolute maximum voltage - 40 volts DC. Minimum voltage - 22 volts average DC (with up to 7 volts peak to

peak ripple 94 -126 Hz.)

DC (MDB)

Absolute maximum voltage - 44 volts DC (Typically 34 volts) Minimum voltage - 18.5 volts average DC (with up to 7 volts peak to peak ripple 94 -126 Hz.) NOTE. During the life of the defined products, there will be a

requirement for European equipment (whole vending machine) to operate at 230 V +6%, -10%. Most countries except UK have agreed to this change. The 240V transformer design is such that this change can be accommodated.

VOLTAGE TRANSIENTS

Minimum performance can be regarded as that stated under the section on susceptibility.

The unit will perform to criteria A for supply loss (100%) of up to two cycles.

For supply loss of greater than 2 cycles then performance criteria B applies.

For DC (BDV / MDB) units, voltage transients that go below the minimum average level - peak ripple voltage, will cause variance to performance criteria B. (i.e. loss of credit).
