Frequently Asked Questions

General

Q: Are Coinco and Coin Acceptors the same?

Yes; Coin Acceptors, Inc. is the official corporate name. Coinco is a trademarked derivation that is widely used to describe the company and its products thus, they are synonymous.

Q: Do you sell or service products other than your own?

Coinco sells and services only its own products. We do not sell used or reconditioned products. Some control boards used in electronic vending machines are designed and manufactured by us, but the company that sells the machine should provide the service.

Q: There are many different interfaces for coin changers. How do I know which is used in each machine if I need a spare or a replacement?

The most common coin changer interfaces are as follows:

Executive: Also know as Protocol A. The changer is typically 24 volts, and has two harnesses. The first is a 9-pin connector with 5 actual pins used for communication. The second is a 15-pin connector with 3 actual pins used for power. A Coinco changer will have an 'A' as a prefix in the model number or an A as the third character.

MDB: This is the new industry standard and most new electronic machines use it. A 6-pin connector is standard and the changer, bill acceptor and other components connect to the control board and each other with it. Power is 34 volts DC. a Coinco changer will either have an 'G' as a prefix in the model number or an X as the third character.

Single Price: Usually 110-volt beverage machines with an 8-pin connector from the coin changer. Vend price is set in the changer and a Coinco changer will have either an 'S' as a prefix or an 'F' as a prefix in the model number. The machine will not have an electronic control board.

Four Price: Usually 110-volt beverage machines with an 8-pin connector from the coin changer. The four vend prices are set in the changer and a Coinco changer will have an 'F' as a prefix in the model number. The machine will not have an electronic control board.

BDV: BDV is a German standard. The changer is typically 24 volts DC, and has a single 9-pin connector. A Coinco changer will have an 'B' as a prefix in the model number.

Q: Where can I get the MDB specification?

The MDB (Multi-Drop Bus) specification is available from NAMA

Coin Changers

Q: How do changers detect good coins from slugs?

Electronic changers measure coin characteristics by an array of electronic sensors located in the coin path just after entering the acceptor. Before the coin reaches the end of the track, it has been determined to be good or bad and its value has been determined. It then goes to the sorting area to be loaded into change payout tubes, or to the cash box. Older mechanical changers measure thickness, diameter and dynamic characteristics as the coins roll through the acceptor. As they exit the acceptor, they have been determined to be good or bad based on the tests and the good ones have been separated from each other. The coins then actuate switches in the coin changer to send credit pulses to the logic in the changer to be added together to initiate the vend and change payout.

Q: Why doesn't my changer accept any coins?

There are several reasons for a coin changer not to be accepting coins, these range from the machine itself inhibiting the coins through to a failure on the changer unit. Because of this there is no definitive answer to this question. It is always worth cleaning the validation gate on the acceptor to see if this is affecting the acceptance level (see information sheet below for instructions). If this does not solve the problem, the changer has a full range of built-in diagnostics tools to allow for the diagnostics of acceptance issues (please refer to test procedures or call your local Coinco branch for further information).

Q: What do I do if I find a fake or foreign coin in my changer?

Please report any fake or foreign coins found in any Coinco products to your local Coinco branch. We will then endeavour to find a solution in the most time effective manner possible. This could involve the tightening of the validation window on that specific coin type (this can be performed on site) or we may have an updated coin tune to enable the coin to be removed.

Global 2 / €

Q: How do I set a float level?

The Global 2/€ coin changer supports two types of float level: Standard and Pay-down. In Standard Float Level Mode, once a tube float level is set, the changer will try to maintain the set level of coins in the tube by routing accepted coins to the tube only if a coin was paid out. Once the tube reaches its float level in Standard Float Mode, any coins normally routed to that tube will be sent to the cashbox. As usual, any cashbox coins will be accepted and routed to the cashbox. In Float Pay-down Mode, the acceptor will continue to route coins to the tube until the upper sensor is covered. The coins will then be routed to the cashbox. Once a tube float level is set, activating Float Pay-down will dispense coins above the established levels until the coins reach the float levels.

Setting All Four Float Levels At Once:
1. Load the four coin tubes to the float level you want the coin changer to maintain.
2. Enter Display Mode by pressing buttons A and D simultaneously. The display will turn on the message FILL, FULL, or AbCd.
3. Press B to scroll up to Address A007.
4. Press C to enter Address A007. The display will show the current float mode settings for all tubes. The far left digit represents tube A through the far right digit representing tube D.
5. Press B (increase) or D (decrease) to 1 to set standard float levels, 2 for float pay-down, or 0 to disable float mode.
6. Press C to enter your selection. The far right decimal point will illuminate indicated the selection has been stored.
7. Press A to return to the Address selection.
8. Press A again to exit display mode. All four tube float levels are now set. The Digital Displays second decimal point from the right will be illuminated if any tube float levels have been set.

Setting Float Levels Individually:
1. Load the individual coin tube to the float level you want the coin changer to maintain.
2. Enter Display Mode by pressing buttons A and D simultaneously. The display will turn on the message FILL, FULL, or AbCd.
3. Press B to scroll up to Address A008 for individual tube float setting.
4. Press C to enter the Address.
5. A will be displayed indicating tube A. Use button B (increase) or button D (decrease) to reach the desired tube selection.
6. Press C to enter the Sub Address.
7. Use button B (increase) to reach the correct setting (0 to disable, 1 for standard float, 2 for float pay-down).
8. Press C to store setting. The far right decimal point will illuminate indicating the selection has been stored.
9. Press C again to return to the Sub Address Display.
10.Press A to return to the Address Display.
11.Press A again to exit the Display Mode. The tube float level is now set for the individual tube you have chosen. The Digital Displays second decimal from the right will be illuminated if any tube float levels have been set.

Activating Float Pay-Down
Pressing and releasing buttons A and B simultaneously activates Float Pay-down. Use Manual Fill to replenish low tubes.

Q: How do I manually fill the coin tubes?

The simplest method for filling the change tubes is to utilise the manual loading door on the acceptor. This will allow for the fastest possible filling of the tubes. There are restrictions on some machines to the use of the manual fill door, if your machine does not allow this method of tube fill then the changers "Manual Fill Mode" can be used. Manual Fill Mode allows coins to be inserted into the acceptor which routes the coins to the proper coin tube without establishing credit. When high sensor level or float level is reached and in manual fill mode, coins will be rejected. Enter the Display Mode by pressing the A and D buttons simultaneously. When FILL appears in the display, deposit coins until the desired level. Alternating with the FILL message will be the tubes needing coins AbCd. The changer will automatically return to operating mode after 45 seconds of no activity or if button A (escape) is pressed. Manual Fill Mode is supported for Single-/Four-Price, Protocol A, and BDV changers. Manual Fill Mode in MDB changers is accessed through the vending machine controller. See vending machine manual for details.

Q: How do I set the vend price?

Setting The Vend Price On A Four-Price Changer
The vend price can be set in single increments up to 255 times the lowest denomination coin that is accepted by the changer and routed to a coin tube. E.g If the lowest denomination coin is 1, the highest vend price setting would be 255
Switch 1 ......................................... 1 x Scaling Factor
Switch 2 ......................................... 2 x Scaling Factor
Switch 3 ......................................... 4 x Scaling Factor
Switch 4 ......................................... 8 x Scaling Factor
Switch 5 ....................................... 16 x Scaling Factor
Switch 6 ....................................... 32 x Scaling Factor
Switch 7 ....................................... 64 x Scaling Factor
Switch 8 ..................................... 128 x Scaling Factor
Setting prices via the option switches Note: The switches are ON in the upwards position.
1. To set the vend price of a selection, add the value of the rocker switches that are switched to the ON position.
2. Set Option Switch B to the ON position.
3. Set Option Switches A, C and D to the desired configuration
4. After setting the desired vend price on the Option Switch Module, press and release the Mode Button. The changers Main Logic Board LED and the Use Correct Change light will begin to flash.
5. Within 30 seconds, press and release any one desired product selection switch on the front of the machine. The present price on the switch module is now set for all selections on that price line and the LED and Use Correct Change light will stop flashing.
6. Repeat the above steps until the remaining three price lines have been assigned a vend price. E.g If the first, fourth and fifth price setting switches are in the UP position, the vend price setting would be 25 x 1 or 25 (assuming the lowest denomination coin accepted is 1). NOTE: If the price for one or more of the selections is set to zero, that selection is a free vend.

Setting The Vend Price on MDB and BDV Changers
Vend prices for MDB/BDV changers are set through the vending machine controller (VMC). See vending machine manual for details.

Q: How can I find out how many coins my changer has accepted?

The Global 2/€ Executive and Single/Four-Price coin changers have full DEX audit capabilities. This gives total history of the changers performance and will provide information such as number of vends, total value of coins accepted etc.

Q: How do I clear a payout jam?

Although every effort has been made to ensure that the pay out mechanism on the Global 2/€ changer is as reliable as can possibly be there may be times when a coin becomes jammed in the payout base area of the changer. This normally occurs due to a bent or damaged coin being accepted by the changer or can be caused by the wrong coin type being sent to or manually filled into the wrong tube.

Quantum € Coin Changers

Q: How do I set a float level?

Float Mode is used to reduce the number of coins kept in a tube to a level anywhere between the upper and lower tube sensors. The Quantum changer supports one of two factory programmed Float Mode operations. They are Float Level and Float Pay-Down.

Float level (standard on EUQ models)
In Float Level, coins are filled to a chosen level between the upper and lower tube sensors. Once the Float Level is set, coins will only be routed to the tube if a coin was paid out for change. Accepted coins normally routed to that tube will be sent to the cash box.

Float pay-down
In Float Pay-Down, coins are filled to a chosen level between the upper and lower tube sensors. Once the level is set, coins will continue being routed to the tube until the upper sensor is covered, then they will be routed to the cash box. Activating the Float Pay-Down by pressing inventory buttons A and B simultaneously will pay down any coins above the level you previously set. After the coins are paid down, the acceptor will automatically go into manual fill mode. In manual fill mode, the acceptor will only route coins to tubes that are below the set level. Once the level is reached, the coins will be rejected.

Setting the float mode levels
The Float Mode Levels for both Float Level and Float Pay-Down are set for all four tubes using the acceptor inventory buttons.
1. Using Tube Fill, Coin Fill, or Manual Fill mode, fill the four tubes to the float level you want the changer to maintain.
2. Press and release the A and D inventory buttons simultaneously. The acceptor LED will flash an equal ON and OFF pattern.
3. Within two seconds, press and release inventory buttons B and C at the same time to store the tube levels and turn the Tube Float Mode ON. The acceptor LED will now display a flash pattern of 10% ON and 90% OFF to indicate the levels are set.
Note: To turn off the Float Mode, repeat steps 2 and 3.

Activating float pay-down
Press and release acceptor inventory buttons A and B simultaneously. After the tubes pay down, Manual Fill Mode is automatically entered to allow low tubes to be replenished through the acceptor. When the float levels are reached, coins are directed to the coin return. The changer will automatically return to operating mode after 45 seconds of no activity or if any inventory button is pressed and released.

Q: How do I set the vend prices?

Vend prices for MDB coin changers are set through the vending machine controller (VMC). See vending machine manual for details.

Q: How do I manually fill the coin tubes?

Manual fill mode can be used to fill the tubes of the coin changer, through the acceptor, without accumulating credit and having to vend the credit away. To enter the Manual Fill Mode, press inventory buttons C and D at the same time. The acceptor LED will flash an equal pattern of ON and OFF to indicate the Manual Fill Mode is active. Coins inserted through the acceptor will be routed to their? proper tubes. When the upper tube sensor is reached, coins will be directed to the cash box or to the next tube of like coins. The changer will automatically exit Manual Fill Mode after 45 seconds of no activity, or if an inventory switch is pressed and released.
