Note: Escrow may not be paid if the VMC is set for NoEscrow Return. Refer to Vending Machine Manual foroperation, if applicable.
Single Price InterfaceSINGLE PRICE INTERFACE ESCROW TO VENDFor an escrow to vend (standard) operation, a vend relayis required in the vending machine. In the Escrow toVend (ETV) coin changer accumulated credit is comparedto the price set in the control logic of the coin changer ascoins are inserted. If adequate credit exists and ifrequired change is available, the control logic activates the vend relay in the coin changer. The coin changer'svend relay then connects the AC hot line to the vendrelay in the machine. The latching of this relay opens theblocker contacts and enables the select switches.Activation of a select switch causes the vend motor toturn. The vend motor mechanically activates a carrierswitch which holds power on the motor and deactivatesthe vend relay in the machine. The deactivation of thevend relay cancels credit and initiates the change-making cycle, if required.
SINGLE PRICE INTERFACE ESCROW TO SELECT(for TRC-6800 changers with CIGARETTESwitches)For an escrow to select (cigarette) operation, a vendrelay is not required; however, an external sense circuitis needed. This is normally supplied by the activation ofa select switch. In the Escrow to Select (ETS) changer,accumulated credit is compared to the price set in thecontrol logic of the changer as coins are inserted.The activation of a select switch causes a sense currentto flow in the coin changer. If adequate credit exists andif required change is available, the control logic activatesthe vend relay to connect the AC hot line to the selectswitch. This causes the vend motor to turn. The vendmotor mechanically activates a carrier switch whichholds power on the motor and opens the blockercontacts. The opening of the blocker contacts is thensensed by the coin changer. The coin changer thendeactivates the vend relay, cancels credit and initiates the change-making cycle, if required.

Figure 7: TRC6800 Power Plug
Micromech InterfaceThe Micromech interface transmits data to the externalVMC via its INTERRUPT and DATA lines. The controllerresponds to these messages via its SEND line. Thesethree lines form the serial data link between changerand controller. The VMC supplies power to operate thechanger via its four power lines. In addition, the VMC
has five control lines that authorize coin payout,enable/inhibit coin acceptance, and reset the changer toits standby condition. Refer to Figure 8 for power plugpinout.
Micromech Electronics Operation Sequence
When a coin enters the mechanism, an "interrupt"signal is sent on Pin #4 to inform the VMC that themechanism is ready to send credit information.
When the VMC receives this "interrupt" signal, itsignals the mechanism via a "send" signal on Pin #3.This indicates to the mechanism that the VMC isready to accept "data".
When the mechanism receives this "send" signal, ittransmits a message on Pin #5 containing thefollowing data:
coin value - 5¢, 10¢, 25¢ or $1.00.
coin tube status - coin tube sensors are covered/notcovered.
coin direction - to coin tube or to cash box.
If a coin is rejected, or if there is a problem in themechanism, certain default messages are sent to theVMC on the "data" line. They are as follows:
slug - coin entered but was not accepted (accept gatedid not open).
no strobe - coin was accepted but did not actuatestrobe (could indicate jam or strobe issue) dollarcoins rejected due to insufficient quarters in the cointube or sensor in the coin tube.
power up - indicates coin changer was just reset orpowered up.

Changer Operation
Micromech Interface Special Features
Accept Enable - Whenever the VMC sends the"accept enable" signal on Pin #6, the mechanismsends the "coin tube status" message. This can beused while dispensing quarters to see when thecoins uncover the lower sensor. At that time, thechanger can dispense four more coins from thattube. It can also be used by the VMC to determine ifthe mechanism is operating by sending the "acceptenable" message every so often when no transactionis taking place.
Reset (Pin #11) - this line enables the VMC to resetthe microprocessor of the mechanism in the eventthere is a low power condition on the 5 volt line.
When sufficient credit has beenestablished in the VMC to enable a vend,the VMC performs the changemaking logicand sends logic +5V signal(s) to operatethe appropriate 5¢, 10¢ or 25¢ dispensersolenoids in the mechanism for change(if needed).
Micromech Interface ExceptionsThe 15-pin Micromech interface is aduplicate of the 12-pin Micromechinterface with two exceptions:
Pin #14 enables dollar coin dispense.Not all VMC manufacturers utilize thiscontrol line.
The 110VDC is referenced on pins 10and 12; 24VDC is referenced on pins13 and 15.
Note: Some manufacturers utilize a 24VDCsystem exclusively. In those applications,you may find that they will jump pins 10 to13 and pins 12 to 15. This enhances theinstallation for either TRC6010 orTRC6010XV coin changers by using thesame socket.
Note: When the number of coinsintroduced exceeds the highest priceprogrammed into the VMC, acceptancewill cease.

Multi-Drop Bus InterfaceMulti Drop Bus (MDB) SpecificationsThe TRC-6510 and TRC-6512 are configured as peripheralsto a VMC along with the bill validator, card reader, etc.They rely fully on the VMC for a constant communicationthat occurs during either idle or operational procedure.The two lines that are utilized for this process are: TXdata line (Transmit Data) and RX data (Receive Data)lines. These lines operate at a 9600 baud rate.
RX Data - enables the changer to accept coins,informs the coin changer that it is ready to receivedata; the changer determines what change will bedispensed.
TX Data - informs the microprocessor that a vendcycle has been initiated, depending on whatdenomination has been accepted.
This communication enables or disables acceptanceand coin dispensing during a transaction. The coinchanger simultaneously communicates with the VMC
regarding the type of coin that has been accepted andthe availability of change that may be required for thenext transaction. The routing of the coin, either to thecash box or to coin tubes, is determined by the coinchanger. Figure 9 shows the power plug of the TRC-6510
or TRC-6512 coin changer.

Figure 9: TRC6510/TRC6512 Power Plug
Changer Operation
As the coins roll along the ramp, they pass twoelectronic sensors embedded in the plastic behind thecoin path and Acceptor lid (Figure 10). The recognitionsensors measure coin diameter/metal content and cointhickness. These values, which are sent to the changer'smicrocomputer for analysis, determine whether the coinwill be accepted.
The microcomputer compares the information receivedabout the inserted coin to the predetermined coinacceptance criteria stored in memory. If a coin fallswithin the range of acceptable specifications, it isaccepted. The microcomputer sends a signal to theAccept Gate, opening the Accept Gate and routing thecoin to the Separator section.
As the coin enters the Separator section, it passes theStrobe Sensor. This electromagnetic coil signals themicrocomputer that a coin has been accepted.The microcomputer then accumulates credit equal to thevalue of the accepted coin, and closes the Accept Gate inpreparation for the next inserted coin.
Coin RejectionCoins not meeting the acceptable specifications arerejected. The Accept Gate remains closed, and therejected coin rolls off the top of the gate, down a rampto the reject chute, and drops into the coin return cup.
Changer OperationGeneral OperationWhen coins are inserted into the coinchanger, they pass two electronic sensorsthat measure coin diameter, metal contentand coin thickness. These measurementsare sent to the coin changermicrocomputer where they are comparedwith predetermined coin acceptancecriteria.
If the coin does not meet the acceptancecriteria, the Accept Gate remains closedand the coin is rejected. If it fits the criteria,the coin is accepted. The Accept Gateopens to allow the coin into the Separator section. As it enters, it passes the StrobeSensor, which signals the microcomputerto accumulate credit.
Each time a transaction occurs, themicrocomputer checks the status of theupper coin tube sensors to see if the tubesare full. If the tube corresponding to theaccepted coin is full, the Separator Gateremains open and the coin is sent to thecash box. If the appropriate tube can acceptcoins, the Separator Gate closes and thecoin is routed to that tube.
Once a vend price has been reached, themicrocomputer checks the lower coin tubesensors for change requirements. Coins ofthe highest denomination available areselected and the dispensers pay out thechange.
Coin AcceptanceWhen coins are inserted into the vendingmachine, they enter via the Coin Cup of theAcceptor/Gate Assembly. The coins hit twosnubbers that absorb the impact and allowthe coins to roll smoothly down the coinramp.

Changer Operation
Figure 10: Coin Paths
Coin SeparationAccepted coins are directed to the cointubes or cash box by the Separator Gate.Each time a transaction occurs, themicrocomputer checks the upper coin tubesensors to determine whether or not thetubes require coins. The Separator Gate isdirected accordingly.
If the appropriate coin tube is full (sensorcovered) or the coin is not stored forchange, the Separator Gate remains open.This sends the coin directly to the cash boxvia the cash box chute.
If the tube requires coins (sensor exposed)and the coin is stored for change, thechanger microcomputer closes theSeparator Gate. This directs the coin downa path that contains windows leading intothe coin tubes. As the coin reaches awindow of the correct diameter, it falls intothat window's tube.
Coin Payout/Coin ReturnCoin payout can result from a transaction - escrow returnrequest, exact change condition, or change making froma completed vend - or by manually reducing theinventory levels in the coin tubes. Coins selected arepaid out by the Dispenser Assembly.
Whenever possible, escrow return is paid coin-for-coinfrom the coin tubes. Escrow for coins that are not storedfor change is paid utilizing the highest denominationcoins available in the coin tubes.
In general, escrow return for dollar coins and bills is paidin the highest denomination coins available from thecoin tubes. Payback is assured by the minimum cointube levels required for dollar coin and bill acceptance.
Note: If No Escrow Return is selected, there is nominimum coin tube requirement for the acceptance ofdollar coins or bills. Consequently, full payback may notbe possible.
Change Making
Change is paid out by the Dispenser Assembly utilizingsolenoid-operated slides. Each time a transactionoccurs, the changer microcomputer checks the status ofthe lower coin tube sensors to see which coins areavailable for change. Highest denomination coins arepaid back first. During a transaction, nickels, dimes andquarters are paid out to the level of the lower coin tubesensors. When used with a low level interface to a billacceptor, the TRC coin changer will not allow acceptanceof a dollar bill or coin if the lower dime and quartersensors are uncovered and more than seven nickelswould be required for change.

Changer Operation / Maintenance
TuningTRC coin changers are factory preset to maximize validcoin acceptance. However, periodic adjustments may berequired to correct differences that can occur when theAcceptor/Gate Assembly and/or the ControlBoard/Backplate Assembly are replaced. (No specialtest equipment is required for tuning adjustments.)
In the Tuning Mode:The coin changer is taught to recognize a set of coins.As the coins are inserted through the Coin Cup, they areplaced into eight different tuning locations - twolocations per denomination [(nickel, dime, quarter, dollar,Canadian and U.S.) Tokens on TRC-651x]. Two coins ofthe same coinage may be used for acceptance.The TRC-60x0 or TRC-6800 may also be taught to accepta token in lieu of a coin.
Note: Dimensions and metal content will affect thedegree of success in using a token.
Depressing the Coin Return Lever during the tuningprocedure clears that tuning location.
After tuning, the changer switches to a calibration mode.This mode serves as a fine-tuning function. Acceptancewill improve with the number of coins inserted.
Preparation - (In Vending Machine or Tester)If tuning is required, perform these steps first:
1) Set one vend price to the highest programmableprice and activate the door switch for machine.
2) Turn the machine OFF.
3) Lower the Acceptor/Gate Assembly.
Manual Dispensingof CoinsOperating the manual dispense switches /buttons reduces the level of coins in thecoin tubes by operating the properdispenser solenoid. Coins are dispensedat a rate of two per second. The VMC ofthe vending machine is responsible forsending the dispense signal to theTRC60X0 or TRC-651X coin changers.Refer to the vending machine manual foroperation procedure for dispensing ofcoins from changer.
Solenoid OperationWhen a solenoid energizes, the upwardmotion of its plunger compresses a springand draws the solenoid lever, which in turnpushes a payout slide forward (Figure 11).This loads a coin for payout. When thesolenoid de-energizes, the spring forcereturns the plunger to its de-energizedstate, which returns the solenoid lever,returning the payout slide, paying out acoin.
Figure 11: Solenoid Operation

Maintenance
4) Set the changer option switches as follows (ifapplicable for your model coin changer):
ON U.S./ Canadian AcceptanceOFF High 25¢ SensorON $ Coin AcceptanceON $ Coin Acceptance w/o 25¢
5) Short the set of tuning pins by touching bothsimultaneously with the tip of a metal screwdriver/tuning plug; MEI P/N 208240001 PAK 5. (See Figure12 or Figure 13 on this page).
6) With the screwdriver/tuning plug still touching thetuning pins, turn machine ON.
7) Remove the screwdriver/tuning plug when the"normal" message appears on the display of themachine.
8) Press the Acceptor/Gate Assembly back into positionuntil the spring clips engage.
The changer is now in the tuning mode. Now you are
ready to follow the Tuning Coin Sets.
Follow TUNING COIN SET listed below.

Maintenance
To Clean the Acceptor and Coin Ramp:
1) Swing the Acceptor lid diagonally upward and to theright (see Figure 14). Hold the lid firmly so that it doesnot snap back down.
2) Wipe the exposed coin ramp and inner surface of thelid with a damp cloth. For problem cleaning, dampenthe cloth with water and mild, non-abrasive soap.
Note: When teaching proper use of a TRC-60X0C forCanadian currency only, substitute a pre-1981 Canadiannickel in the first step and use a post-1981 nickel in thesecond step. All other models should use the post-1981nickel. It will not accept the Canadian $2 coin.
To Calibrate the Coin Changer: Drop fifteen coins of each denominationinto the coin changer following the tuningorder.
To Tune a Changer for OneDenomination only:Depress the Coin Return Lever after eachinsertion to move to the next denominationcoin. Or insert a second coin of the samedenomination rather than depressing theCoin Return Lever.
Routine MaintenancePeriodic routine maintenance improves theperformance and extends the optimumworking life of the coin changer. It can alsoreduce the need for more costly repair orreplacement measures. Frequency ofroutine maintenance will depend on theenvironment and the number of vendingmachine transactions.
CleaningBefore cleaning, be sure to turn themachine OFF and unplug the coin changer.The TRC coin changer should be cleaned
only with warm water and a mild detergent
solution.
CautionNever immerse the coin changer in
water.
Do NOT use solvents, steel wool,
scouring pads, or metal brushes for
cleaning.
Do NOT spray the coin changer with
any types of lubricant.
Since all coins roll down a common coinramp, heavy use can result in dirt buildup.
Figure 14: Cleaning the Acceptor Coin Ramp
To clean the Dispenser Slides:
1) Detach the Bottom Plate by removing the sevenPhillips head screws - one screw on each side (A), onerecessed screw on the back (B), and four screws on thebottom of the changer (C) (see Figure 15).
2) Lift out the Bottom Plate and individual slides.Clean them with a mild soap solution. Do not spray withany type of lubricant.
