7 G-18.mft with vending machine control system GENERAL INFORMATION 1 General information This chapter should provide a general overview of the advantages and options regarding the coin validator G-18.mft with a vending machine control system for 1-5-chute machines. The first section, however, is designed to help you navigate easily within these operating instructions. General information about these instructions These operating instructions describe the design and operation of the electronic coin validator G-18.mft with a vending machine control system for 1-5-chute machines. Chapters 6 und 7 explain the necessary steps for starting up and operating the coin validator. Chapter 8 explains how to clean the coin validator and remedy the cause of a malfunction. The appended index and glossary reduce the search for specific explanations. Since the G-18.mft can be used not only as a vending machine control system for 1-5-chute machines but also in other operating modes, these operating modes have been briefly described in Chapter 3. You will find a detailed description and instructions regarding the use of these operating modes in the separate general operating instructions for the G-18.mft. To make it easier for you to navigate within these instructions and to operate the device, the following accentuations were made in the text: Safety instructions that must be taken into account in order to protect operators and equipment have been written in bold and provided with the pictogram. Special notes, which are to facilitate the use of the coin validator, have been written in italics and also been given a pictogram. Requests to perform an action are numbered in another typeface. At the beginning of a chapter you will find a short "guide", which summarizes the content of the chapter. National Rejectors, Inc. GmbH, Buxtehude 7

8 GENERAL INFORMATION G-18.mft with vending machine control system To configure and test the coin validator reference is made to the separate documentation of the NRI PC software "WinEMP", of the NRI Palm handheld software "PalmEMP" and of the NRI testers (refer also to Chap. 9 "Which functions can be set using WinEMP/PalmEMP?"): WinEMP The configuration and diagnostics program for NRI coin validators, operating instructions for the G-18 PalmEMP Operating instructions for configuration of the coin validator G-18.mft Tester G /4 If this documentation is not available to you, it can be downloaded at any time from the NRI homepage ( in the compressed PDF format. General information about the coin validator The battery-operated and microcomputer-controlled electronic coin validator G-18.mft (multi-frequency technology) is the successor model of the G , whose reliable measuring sensor system and rejection of false coins system were taken over and which has been designed in accordance with the BDTA standard (Bundesverband Deutscher Tabakwaren-Großhändler und Automatenaufsteller) (federal association of German tobacco product wholesalers and vending machine installers). Because of its printed circuit board, which is protected against moisture and high temperature variations, this is the ideal coin validator for power-supplyindependent vending machines in outdoor service use. To be able to react as quickly as possible to new false coins and to enable you to make your individual adjustments, this coin validator can be connected to (cp. also section "Accessories" in Chap. 10 "Technical data"): a PC programming station, which consists of the configuration and diagnostics software "WinEMP" (including card reader and chip card) and an NRI tester. a mobile Palm handheld, on which the NRI program "PalmEMP" has been installed, if the coin validator is to be configured on site in the vending machine. Old coins and new coins being added to a currency that have not been taken into consideration at the manufacturer can be programmed on the coin validator (optional teach mode). 8 National Rejectors, Inc.

12 OTHER OPERATING MODES OF THE G-18.MFT G-18.mft with vending machine control system 3 Other operating modes of the G-18.mft Since the G-18.mft can not only be used as a vending machine control system for 1-5-chute machines but can also be used in other operating modes by setting the switches, this chapter will now provide a brief description of the other operating modes. The device can work in parallel operation as a standard coin validator 1-price totalizer or 2-price totalizer and in serial operation according to the S1 protocol, BDTA MDB slave protocol or MDB master protocol. You will find a detailed description and instructions regarding the use of these operating modes in the separate general operating instructions for the G-18.mft. Parallel operation For vending machines with a parallel interface, the coin validator G-18.mft can be used in two different operating modes, i.e., as an exclusive coin validator or as a totalizer (1-price and 2-price totalizer). Coin validator operation The G-18.mft is used as an exclusive coin validator whenever coins inserted into a vending machine are checked for their properties and are to be accepted for sale or rejected and directed into the return area as a result of this inspection. Totalizer operation The G-18.mft is used as a totalizer whenever it is supposed to data-manage prices internally in addition to the coin inspection (see above). The G-18.mft compares these prices with the total value of the inserted coins. If the credit reaches the price, the totalizer uses a price signal to trigger the handing-out of the goods by the machine. The totalizer can be used as a 1-price totalizer for setting one price or as a 2-price totalizer for setting two prices. 12 National Rejectors, Inc. GmbH, Buxtehude

13 G-18.mft with vending machine control system OTHER OPERATING MODES OF THE G-18.MFT Serial operation For vending machines with a serial interface, the coin validator G-18.mft can be used in two different operating modes, i.e., as a slave or as a master. Slave coin validator operation In slave operation, the G-18.mft is used as an exclusive coin validator. The coins inserted into a vending machine are checked for their properties and are accepted for sale or rejected and directed into the return area as a result of this inspection. The communication of the coin validator with the vending machine control system is carried out via the MDB protocol or the S1 protocol. Accordingly, the vending machine functions as a master and the coin validator as a slave. The MDB protocol (MDB = Multi Drop Bus) is used in the case of the G-18.mft with BDTA (BDTA = Bundesverband Deutscher Tabakwaren- Großhändler und Automatenaufsteller) (federal association of German tobacco wholesalers and vending machine installers) restrictions for: voltage supply and battery operation. The S1 protocol is an MDB protocol specified for NRI coin validators with individual restrictions and commands for: voltage supply and sorting. You can obtain further information about the MDB interface and S1 interface in the BDTA MDB specification, which is available to you at the BDTA NRI S1 specification for the G-40 S1, which NRI will gladly place at your disposal upon your request. Master operation The G-18.mft is used as a master whenever it is supposed to control devices via the MDB protocol in addition to the coin inspection (see above). The communication of the coin validator with a card reader, display or other external device is carried out via the standard MDB protocol (MDB = Multi Drop Bus), with the coin validator functioning as a master and all connected devices, such as a card reader or display, functioning as a slave. You will find detailed information about the MDB interface in the "NAMA document MDB/ICP, 2.0" ( National Rejectors, Inc. GmbH, Buxtehude 13

14 DESIGN G-18.mft with vending machine control system 4 Design This chapter describes the general design of the coin validator and the additional control PCB and also the components that are important for operating the device: Return lever, switching blocks, light-emitting diode, interfaces, label Interfaces, button and switches, pilot lights The coin validator Fig. 1a: Design G-18.mft 1 Return lever 2 Coin insert funnel 3 Switching blocks S1 S3 4 Mounting studs 5 MDB interface optional periphery (display, card reader) 6 Interface additional control PCB 7 Light-emitting diode 8 Interface additional control PCB 9 Coin outlet 10 Configuration interface PC programming station (WinEMP)/ Palm handheld (PalmEMP) 14 National Rejectors, Inc. GmbH, Buxtehude

15 G-18.mft with vending machine control system DESIGN Coins inserted into the coin validator pass through the coin insert funnel 2 into the measurement and validation area of the device, where their coin properties are compared with the values of the stored acceptance bands. Coins rejected by the coin validator are directed into the return area and coins accepted for the vending operation leave the device through the coin outlet 9, which is located at a fixed position because the coin validator does not have a sorting function. (See Fig. 1a) Return lever The return lever 1 on the top of the coin validator is either directly operated mechanically or motor-controlled using the return button on the vending machine, if the coins which have already been inserted are to be returned or a jam caused by coins, e.g., which have become stuck needs to be removed. Operating the return lever opens the measurement and validation area of the coin validator so that all objects in the coin validator are transported into the return area. (See Fig. 1a) National Rejectors, Inc. GmbH, Buxtehude 15

16 DESIGN G-18.mft with vending machine control system Switching blocks (on coin validator) On the rear of the device, the coin validator is equipped with three switching blocks (S1 S3) 3 located below one another. The two upper switching blocks S1 and S2 have eight DIL switches each, and the lower block S3 has ten. (See Fig. 1a) The 12 available coin channels or the coin types assigned to the coin channels can be inhibited individually using the first six DIL switches of switching blocks S1 and S2 (see section "Inhibiting coins" in Chap. 7 "Operation"). DIL switch 7 on the switching block S1 is used to determine whether the customer will receive his goods if he has a credit that corresponds exactly to the price or also if his credit is higher than the set price (see section "Set exact price or overpay mode" in Chap. 6 "Starting up"). Using the eighth DIL switch of the upper switching block S1, you can disable the operating button and operating switches of the additional control PCB (see section "Disabling price and test switches/button" in Chap. 7 "Operation"). DIL switch 7 on the lower switching block S2 is used to set the coin validator into teach mode in order to be able to configure new coins or tokens on site without using any additional tools (see section "Teaching coin channels in teach mode" in Chap. 7 "Operation"). The eighth DIL switch of the middle switching block S2 is used to define the operating mode "vending machine control" (see Chap. 6 "Starting up"). The DIL switches 1 8 of the lower switching block S3 are not assigned in the operating mode "vending machine control". Their switch position is not relevant. DIL switch 9 of the switching block S3 is used to set the MDB protocol and DIL switch 10 is used to select which of the two memory blocks the coin validator is to access (see Chap. 6 "Starting up" and section "Selecting memory block" in Chap. 7 "Operation").

18 DESIGN G-18.mft with vending machine control system Light-emitting diode (on coin validator) The light-emitting diode (LED) 7 (see Fig. 1a) indicates, on the one hand, the voltage state of the battery if the return lever is pressed after a coin has been inserted (see section "Displaying battery voltage" in Chap. 8 "Maintenance and service"). On the other hand, the LED lights up when memory block 0 or 1 is switched active (see section "Selecting memory block" in Chap. 7 "Operation"). 18 National Rejectors, Inc. GmbH, Buxtehude

19 G-18.mft with vending machine control system DESIGN Interfaces (on coin validator) On the rear of the coin validator there is a 6-pole 8 and a 14-pole 6 interface to the additional control PCB (to the vending machine). At the bottom of the device there is a connecting plug 10 for the PC programming station or the Palm handheld. Peripheral devices, such as a display or card reader, can be connected to the 10-pole MDB interface 5. (See Fig. 1a) Interfaces 8/6 additional control PCB (6-/14-pole) These two interfaces are used to connect the coin validator to the additional control PCB to which the vending machine components such as the battery, escrow, selection buttons, pilot lights, product ejectors, and return mechanism are connected (see section "The additional control PCB" in this chapter). Interface 5 MDB periphery (10-pole) If the G-18.mft is operated as a 1-5-chute vending machine control system, use an MDB cable set to connect all slave devices, such as an MDB card reader and MDB display to this interface (see section "Accessories" in Chap. 10 "Technical data"). For further information on the MDB interface, please refer to "NAMA document MDB/ICP, 2.0" ( For details regarding pin assignment, see section "Pin assignment and connection diagrams" in Chap. 10 "Technical data". Pin 7 of this interface has been assigned to a wake-up line. The coin validator itself is woken up from an energy-saving standby mode by the insertion of a coin and then wakes up all connected slave devices via the wake-up line. The coin validator is now in its active state and keeps the wake-up line on "low" = active (all devices ready for operation) until the inserted coin has been processed. Interface 10 configuration (WinEMP/PalmEMP) To configure the coin validator the device is connected to a PC or a mobile Palm handheld. For that purpose, the G-18.mft is equipped at the bottom with a PCB direct plug (see Fig. 1a), which is used to connect the coin validator to the PC programming station or to a Palm handheld. The device can then be set up using the configuration and diagnostics software "WinEMP" or "PalmEMP" (see Chap. 6 "Starting up" and Chap. 9 "Which functions can be set using WinEMP/PalmEMP?"). For details regarding pin assignment, see section "Pin assignment and connection diagrams" in Chap. 10 "Technical data". National Rejectors, Inc. GmbH, Buxtehude 19

For details regarding pin assignment, see section "Pin assignment and connection diagrams" in Chap. 10 "Technical data". Button and switches (additional control PCB) Button 3 is used to perform an automatic run of the vending machine functions such as escrow, selection buttons, pilot lights, product ejectors and motorized return mechanism before starting up the device (see Chap. 6 "Starting up") and to reset the error messages stored in the coin validator that inhibit the further acceptance of coins or disable the selection buttons (see Chap. 11 "Troubleshooting"). The lower of the two DIL switches 2 is used for the manual testing of all contacts of the vending functions such as escrow, selection buttons, product ejectors and motorized return mechanism (see Chap. 11 "Troubleshooting"). The upper DIL switch can be used to set up to five prices for up to five different products (see section "Set the prices" in Chap. 6 "Starting up"). The button and switches can be disabled for normal operation (see section "Disabling price and test switches/button in Chap. 7 "Operation"). National Rejectors, Inc. GmbH, Buxtehude 21

22 DESIGN G-18.mft with vending machine control system Pilot lights (vending machine door) The two pilot lights (LEDs) controlled via the additional PCB (connector 7, Fig. 1c) in the vending machine door are supposed to make it easier for the customer to operate the vending machine in normal operation. However, these LEDs also tell the service technician that there is a malfunction and what kind of malfunction it is. Accordingly, the green LED is used during a correct selling sequence and the red LED in the event of a malfunction or an error during the selling sequence (cp. also section "Status and error messages of the pilot lights in the machine door" in Chap. 8 "Maintenance and service"): green LED flashes, as soon as the inserted credit is sufficient for a purchase: in case of setting "exact price, as soon as a set price is reached and the respective chute is not empty in case of setting "overpay, as soon as the lowest set price is reached red LED flashes, when coins are inserted although the acceptance of coins is inhibited, because: credit has already reached the highest set price all chutes are empty or defective malfunction in the escrow red LED flashes, when a selection button is pressed, because: in case of setting "exact price", credit is not equal to price in case of setting "overpay", credit is less than the price of the selected product chute of the selected product is empty or defective green and red LED flash alternately whenever the coin validator is not in the normal operating mode but in the service mode instead, so that no coins can be accepted in order to generate a credit (e.g. in the test mode or during the price-setting operation). 22 National Rejectors, Inc. GmbH, Buxtehude

23 G-18.mft with vending machine control system FUNCTIONS 5 Functions This chapter describes the functions of the coin validator: Coin acceptance Coin channels and memory blocks Accepted coin sensors Prices Control of the vending machine functions "Battery empty" detection Inhibiting of specific coin types Teach mode (optional) Communication with MDB periphery (optional) Only the functions will be described in this chapter. To find out how to change adjustable functions, refer to Chap. 7 "Operation" regarding settings made directly on the changer, and refer to the separate instructions regarding settings made using the configuration software WinEMP or PalmEMP (cp. also Chap. 9 "Which functions can be set using WinEMP/PalmEMP?"). Coin acceptance A coin inserted into the coin validator initially runs past inductive and optical sensors for the purpose of an inspection in order to measure its coin properties such as the alloy, diameter, mass and minting. An upper limit and a lower limit are stored for each programmed coin type, a so-called acceptance band, so that the coin validator knows whether to accept a coin or not. If the determined measured values of the inserted coin are beyond the acceptance band, the coin detected as being a false coin exits the coin validator via the coin return area. Otherwise, the acceptance gate opens, and after passing the accepted coin sensors, the coin is initially directed into the escrow of the vending machine. The acceptance bands are programmed by the manufacturer according to customer specifications, but they can be changed using the configuration software (see Chap. 9 "Which functions can be set using the WinEMP/ PalmEMP?"). National Rejectors, Inc. GmbH, Buxtehude 23

24 FUNCTIONS G-18.mft with vending machine control system Coin channels and memory blocks For the purpose of coin acceptance, the coin validator possesses 12 "memory slots" that can be assigned different coin types or tokens. These "memory slots" are termed coin channels. All the coin information that describes the processing of an inserted coin is assigned to the coin channels; e.g. the acceptance band of a coin type/token so that the coin type/token is accepted in that channel. To be able to reject false coins reliably, channels with a narrow or even a very narrow acceptance band are frequently set up for a coin type, in addition to the standard coin channel. The limit values of these coin channels are closer to one another so that false coins with similar measured values are rejected. Narrow and very narrow coin channels, however, also possess a lower acceptance rate. In addition, it is possible to allocate coins with different measured values but identical coin values to different coin channels. This is how the coin validator can, for example, accept old and new coins of the same type. However, a coin channel is not only assigned the acceptance band of a coin type but also other coin information which defines further processing: e.g. coin values and inhibiting information. The memory of the coin validator can data-manage two separately programmed (memory) blocks 0 and 1 (see section "Label" in Chap. 4 "Design"). The 12 coin channels can be assigned independently of one another to each block with different coin types (also currencies), inhibiting information, etc. Only one block can be active at a time and be used for the coin measurement and for further coin processing. You can use the switching blocks on the rear of the device to select the desired block (see section "Selecting memory block" in Chap. 7 "Operation"). Since the customer-specific programming made by the manufacturer does not allocate all 12 coin channels of memory block 0 and 1 in most cases, coin types and the desired further information can be assigned to channels that are still free at any time using the configuration software (see Chap. 9 "Which functions can be set using WinEMP/PalmEMP?"). The coin channels 7 to 12 of the two memory blocks are intended for the teach mode. New coin types/tokens can be taught in teach mode directly at the vending machine without using any further tools (see section "Teaching coin channels in teach mode" in Chap. 7 "Operation"). 24 National Rejectors, Inc. GmbH, Buxtehude

25 G-18.mft with vending machine control system FUNCTIONS Accepted coin sensors To ensure that accepted coins actually arrive in the escrow and that coin acceptance has not been tampered with, accepted coin sensors located in front of the coin outlet check whether the inserted coin drops unhindered into the cash-box chute. Only when the coin has passed this checking function is the coin considered accepted. If the accepted coin sensors are continuously covered, e.g. by a coin jam, coin acceptance is inhibited. Prices Up to five prices for up to five different products can be set in the coin validator (see section "Set the prices" in Chap. 6 "Starting up"). All prices are set to EUR 1.00 by the manufacturer. Sale Following the acceptance of coins, the coins are initially directed into the escrow of the vending machine. Depending whether you select "exact price" or "overpay" for the selling sequence (see section "Set exact price or overpay function" in Chap. 6 "Starting up"), the product selection is possible as soon as the inserted credit amounts exactly to the price of the respective product (the credit must not be less than but also not greater than the price). the inserted credit amounts to or exceeds one price or several prices. (The residual credit is accepted without allowing the customer to make another product selection.) The green pilot light flashes until the goods are given out via the respective product chute by pressing one of the up to five selection buttons. Now the accepted coins are directed from the escrow into the cash-box. If the chute selected by the customer is empty or defective, the red pilot light flashes and the customer can now press the return lever. The coins are then directed from the escrow into the return area. The return lever of the coin validator can be directly operated mechanically or electrically by means of a motor.

26 FUNCTIONS G-18.mft with vending machine control system "Battery empty" detection The light-emitting diode on the left-hand side of the coin validator indicates the voltage state of the battery when the return lever is pressed following the insertion of a coin (see section "Displaying battery voltage" in Chap. 8 "Maintenance and service"). Inhibiting of specific coin types If specific coin types are no longer to be accepted for payment at the vending machine (e.g. because there are too many false coins of a specific coin type in circulation), these coin types can be inhibited using the switching blocks on the rear of the coin validator (see section "Inhibiting coins" in Chap. 7 "Operation"). Teach mode (optional) The coin validator provides six memory locations (coin channels) for configuring a maximum number of six new coins/tokens, which means that coin/token measured values can be re-assigned directly on the vending machine by inserting the respective coins/tokens. The acceptance band generated then accepts these tokens as payment in the vending machine. (See section "Teaching coin channels in teach mode" in Chap. 7 "Operation") Communication with MDB periphery (optional) If the coin validator is supposed to control external devices using the MDB protocol, an NRI card reader and NRI display can be connected using the 10-pole MDB interface on the rear of the device and using an MDB cable set (see section "Accessories" in Chap. 10 "Technical data"). 26 National Rejectors, Inc.

GmbH, Buxtehude 29

30 STARTING UP G-18.mft with vending machine control system Perform test run The automatic test run must be performed to ensure that the coin validator "learns" and stores which vending machine components were connected and must be controlled. Starting from the test run, all interfaces that have not been assigned, e.g. only three and not all five product ejector interfaces, are considered "not available". In addition, all components driven by a motor are moved into their final position or initial position. The handing-out of goods is only simulated if the chutes are empty. 1 Unhook the coin validator and set the eighth DIL switch of the upper switching block on the rear of the device upward to ON. The operating elements on the additional control PCB are no longer inhibited and can now be operated. 2 Hang the coin validator back in the machine. 3 Insert a coin into the coin validator. The coin validator is now in the wake-up mode and no longer in the sleep mode. 4 Press button 3 on the additional control PCB (see Fig. 2c). The coin validator is now in the test mode and no longer in the operating mode and activates an automatic test run in the following order: return mechanism, escrow return mechanism, escrow cash-box, product ejectors 1 5, green LED, red LED, acoustic signal 12 3 Fig. 2c: Button and switches on the additional control PCB 5 If the operating elements on the additional control PCB are to be inhibited in normal operation, unhook the coin validator again, set the eighth DIL switch of the upper switching block S1 downward again (to OFF) and hang the coin validator back in the vending machine. 30 National Rejectors, Inc. GmbH, Buxtehude

31 G-18.mft with vending machine control system STARTING UP Set the prices The up to five prices are set by the manufacturer to EUR 1.00 and can be set individually with the help of the upper DIL switch 2 on the additional control PCB by inserting a coin (see Fig. 2c): 1 First unhook the coin validator and set the eighth DIL switch of the upper switching block on the rear of the device upward to ON. The operating elements on the additional control PCB are no longer inhibited and can now be operated. 2 Hang the coin validator back in the machine. 3 Use a pointed object to set the upper DIL switch leftward to ON. The flashing green and red LEDs indicate that the coin validator is no longer in the operating mode. 4 Insert coins until their value amounts to the desired price for chute 1. Only the coins added by the coin validator drop into the escrow. Rejected coins must therefore be inserted again. If the wrong coins were inserted, the price-setting operation can be interrupted at any time by pressing the return button. 5 Confirm the price by pressing the selection button for chute 1. All evaluated coins are paid out. 6 Add up the paid-out coins and, to be on the safe side, compare with the desired price again. If the value is not equivalent to the desired price, not all inserted coins were accepted or added. In that case, the price-setting operation must be repeated. 7 Repeat steps 4 to 6 for all installed chutes. 8 Set the upper DIL switch rightward again (to OFF). The LEDs stop flashing. The coin validator is in operating mode again. 9 If the operating elements on the additional control PCB are to be inhibited in normal operation, unhook the coin validator again, set the eighth DIL switch of the upper switching block S1 downward again (to OFF) and hang the coin validator back in the vending machine. National Rejectors, Inc. GmbH, Buxtehude 31

32 STARTING UP G-18.mft with vending machine control system Set exact price or overpay mode 1 De-energize the coin validator and remove from the vending machine. 2 Set the DIL switch 7 of the upper switching block S1 on the rear of the device upward to ON for "exact price" or downward (to OFF) for "overpay". "Exact price" activated "Overpay" activated 3 Hang the coin validator back in the machine again and supply with voltage. 32 National Rejectors, Inc. GmbH, Buxtehude

33 G-18.mft with vending machine control system STARTING UP Connecting the device environment of the PC programming station (WinEMP) If you want the G-18.mft to be set on the PC using the diagnostics and configuration software WinEMP, the following device environment is connected to the PCB direct plug 5 of the coin validator (see Fig. 2a and section "Accessories" in Chap. 10 "Technical data"): Tester for voltage supply WinEMP card reader incl. chip card Fig. 3: Device environment for WinEMP For details on how to connect the device environment to your PC and how to operate the software, please refer to the separate documentation for the WinEMP software (refer also to Chap. 9 "Which functions can be set using WinEMP/PalmEMP?"). Prior to making the connection to the programming station, the DIL switch S3.9 on the rear of the coin validator must be set upward to ON first, since otherwise it will not be possible to set up a connection to the PC. The WinEMP functions that are relevant for the vending machine control system of the G-18.mft are currently being revised. Connecting the Palm handheld (PalmEMP) "PalmEMP" is an NRI program that can be installed as an additional application on a Palm handheld. Simply use the appropriate dongle to connect the Palm handheld to the PCB direct plug 5 of the coin validator (see Fig. 2a and section "Accessories" in Chap. 10 "Technical data"). The coin validator remains installed in the vending machine. National Rejectors, Inc. GmbH, Buxtehude The PalmEMP functions that are relevant for the vending machine control system of the G-18.mft are currently being revised. 33

34 OPERATION G-18.mft with vending machine control system 7 Operation In this chapter you will find out how to carry out functions and settings, directly on the coin validator using the operating elements (switching blocks and LEDs), rather than with additional tools. Inhibit coins Select memory block Disable price and test switches/button Display battery voltage Teach coin channels in teach mode (optional) Inhibiting coins Using the first six DIL switches of the two upper switching blocks S1 and S2, each of the 12 coin channels or each coin type assigned to a specific coin channel can be inhibited individually, i.e. this coin type is not accepted for payment on the vending machine. Please refer to the label of the device to see which coin type has been assigned to which coin channel by the manufacturer. This assignment can be reset at any time using the NRI software WinEMP or PalmEMP. If all coin types are to be accepted for payment at the vending machine, DIL switches 1 6 of the two upper switching blocks S1 and S2 are in the lower OFF position. If you want to inhibit a coin channel, you only need to set the respective DIL switch upward to ON. The 12 DIL switches inhibit the following coin channels: 34 National Rejectors, Inc. GmbH, Buxtehude

35 G-18.mft with vending machine control system OPERATION Switching block S1 DIL switch off on S1.1 Coin channel 1 vacant inhibited S1.2 Coin channel 2 vacant inhibited S1.3 Coin channel 3 vacant inhibited S1.4 Coin channel 4 vacant inhibited S1.5 Coin channel 5 vacant inhibited S1.6 Coin channel 6 vacant inhibited S1 S2 S3 Switching block S2 DIL switch off on S2.1Coin channel 7 vacant inhibited S2.2 Coin channel 8 vacant inhibited S2.3 Coin channel 9 vacant inhibited S2.4 Coin channel 10 vacant inhibited S2.5 Coin channel 11 vacant inhibited S2.6 Coin channel 12 vacant inhibited S1 S2 S3 Example (the coin validator is no longer supposed to accept the coin(s) assigned to coin channels 3 and 8, which means that coin channels 3 and 8 must be inhibited) With the DIL switches in these positions, the coin validator no longer accepts the coin type(s) assigned to coin channels 3 and 8! To inhibit a coin channel or the coin type assigned to the coin channel: 1 De-energize the coin validator. 2 Inhibit the desired coin channels using the DIL switches 1 to 6 of the two upper switching blocks S1 and S2 on the rear of the device (cp. example above). 3 Restore the supply voltage of the coin validator. If a normal coin channel and a narrow coin channel have been programmed on the coin validator for one coin type, the normal coin channel must be inhibited as described above in order to activate the narrow coin channel. If both channels are activated, the wider acceptance band of the normal coin channel is used. If the coin type is to be inhibited, both coin channels must be inhibited. National Rejectors, Inc. GmbH, Buxtehude 35

36 OPERATION G-18.mft with vending machine control system Selecting memory block The coin validator has two memory blocks, which have been programmed according to customer-specific requirements by the manufacturer. The data of the two blocks 0 and 1 differs in device operation, e.g. by the acceptance of different coin types. If the coin validator is supposed to access the other memory and, e.g., accept coin combination 1 instead of coin combination 2, DIL switch 10 of the lower switching block S3 on the rear of the device can be used to select the correct block. To change the memory block: 1 De-energize the coin validator. 2 Set the DIL switch 10 of the lower switching block S3 downward to OFF if the coin validator is supposed to access block 0 or upward to ON for block 1. Block 0 activated Block 1 activated The LED on the left side of the coin validator lights up briefly. 3 Restore the supply voltage of the coin validator. Disabling price and test switches/button If the operating elements on the additional control PCB are to be inhibited so that they can no longer be operated unintentionally or by anyone, the price and test switches/button can be disabled using the upper switching block S1 on the rear of the device: 1 De-energize the coin validator. 2 Set the DIL switch 8 of the upper switching block S1 downward to OFF. 3 Restore the supply voltage of the coin validator. The operating elements on the additional control PCB are inhibited. 36 National Rejectors, Inc. GmbH, Buxtehude

37 G-18.mft with vending machine control system OPERATION Teaching coin channels in teach mode (optional) Coin channels can also be taught without the configuration software directly on the coin validator using the middle switching block S2, which means that a coin type or also a token is re-assigned to a coin channel by inserting the respective coins/tokens and that the coin validator does not need to be removed from the vending machine. It is also possible to widen the acceptance band of the selected coin channel when, e.g., only a small number of tokens are available. Six coin channels (7 to 12) are available to be taught. The teach mode is optional. The coin channels must be prepared by the manufacturer in order to be able to teach new coins and tokens. The middle switching block S2 on the rear of the coin validator is assigned in the teach mode as follows: Switching block S2 DIL switch off on S2.1Coin channel 7 teach S2.2 Coin channel 8 teach S2.3 Coin channel 9 teach S2.4 Coin channel 10 teach S2.5 Coin channel 11 teach S2.6 Coin channel 12 teach S2.7 Teach mode switch off switch on National Rejectors, Inc. GmbH, Buxtehude 37

38 OPERATION G-18.mft with vending machine control system To re-assign a coin type/token to a coin channel, please proceed as follows: When you use the middle switching block in normal operation in order to inhibit coins remember the current switch settings so that you can restore them easily afterwards. 1 Set DIL switches S2.1 6 downward to OFF. 2 Set DIL switch S2.7 upward to ON. Now the device is in teach mode to teach the coin channels. 3 Enable the coin channel to be taught (7 12, here: 9) by setting the appropriate DIL switch (S2.1 6, here: S2.3) upward to ON. 4 Insert at least 10 coins of the new coin type/token into the coin validator or vending machine. After the 10 th coin has been inserted, the LED on the left-hand side of the coin validator lights up briefly. Additional coins can be inserted. If the LED does not light up after the 10 th coin has been inserted, the inserted coins cannot be used. To abort the operation, first set the DIL switch of the respective coin channel (here: S2.3) and then S2.7 downward to OFF. Now you can save the measured values generated by the inserted coins in either a normal (a) or a wide (b) acceptance band. A wide acceptance band is only an appropriate choice when you only have a limited selection of coins at your disposal for the purpose of teaching tokens and would still like to program greater tolerance limits. To save with the normal acceptance band: 5a Set DIL switch S2.7 downward to OFF. The LED on the left-hand side of the coin validator will light up once if the saving operation has been successful and it will light up twice if there has been an error during the saving operation. To abort the operation, first set the DIL switch of the respective coin channel (here: S2.3) and then S2.7 downward to OFF. 38 National Rejectors, Inc. GmbH, Buxtehude
