    General information about these instructions These operating instructions describe the design and operation of the ECV and MDB models of electronic coin validator G-13.mft. Chapters 5 und 6 explain the necessary steps for starting and operating the coin validator. The index and glossary reduce the search for specific explanations.

  • Page 8: General Information About The Coin Validator G-13.Mft

    The electronic coin validator G-13.mft (Multi-Frequency-Technology) in standardized 3 1/2" format is based on the tried and tested features of the G-13.6000. Due to its modular and compact design, the G-13.mft -is ideally suited for amusement, vending and service machines.

  • Page 9: Models

    ECV, via a serial MDB interface. The machine operates as a master and the G-13.mft as a slave. The G-13.mft MDB is used whenever coins inserted in a machine have to be checked for certain coin properties, exactly like the ECV model.

  • Page 10: Top And Front Entry

    Both models of the G-13.mft are available with top or front entry. The G-13.mft with front entry generally has a MIDI front plate or a MINI front plate fitted to the left-hand side of the device (see Chap. 3 "Construction"). The device is, however, also available as a front entry model without front plate.

    G-13.mft AFETY INSTRUCTIONS Safety instructions Series G-13.mft coin validators are for use in the amusement, vending, and service machines. They have been constructed in compliance with the state of the art and the recognized safety regulations. Nevertheless this equipment can be a source of danger. Therefore please observe the following safety regulations.

Coins rejected by the coin validator pass into the return area 4, Fig. 1a/5, Fig.

  • Page 15: Return Lever

    G-13.mft ONSTRUCTION Coin channels or the coin types assigned to the coin channels can be inhibited via the first six DIL switches of the switching block. To do this the DIL switches are assigned a coin channel randomly. A group of selected coin channels can be assigned to a switch to inhibit a number of coin channels (see section "Inhibit coin channels"...

  • Page 16: Interfaces

    G-13.mft ESIGN Interfaces At the bottom right-hand side of the rear of the coin validator there is a 10-pole connecting plug to the machine (tester) whilst on the left at the centre there is a 3-pole JST plug for connecting an external sorting device. On the left- hand side there is an interface with the programming station or Palm Handheld.

  • Page 17: External Common Inhibit Signal Line

    G-13.mft as a slave. The master can communicate with several slaves (e.g. coin and bill validator). To ensure unambiguous communication each device has its own MDB address. The address of the G-13.mft is "01". The G-13.mft as an MDB model does not fulfil the MDB specification on two counts, i.e.

  • Page 18: Interface - Configuration (Winemp/Palmemp2)

    To configure the coin validator the device is connected to a PC or a mobile Palm Handheld. To do this the back of the G-13.mft has on the right-hand side a 10-pole interface (see Figs. 1a and 1b) which can be used to connect the coin validator to the PC using cable, adapter, card reader and connecting cable, or to a Palm Handheld via a connecting cable.

  • Page 19: Label

    For the MDB model of the G-13.mft there is no assignment of coin signal lines to the coin types.

  • Page 20: Function

    G-13.mft UNCTION Function This chapter describes how the coin validator works, using the route which an inserted coin takes in the coin validator: • Measuring principle and coin acceptance • Coin channels • Accepted coin sensors • Coin impulses and signal lines (not with the MDB model) •...

  • Page 21: Coin Channels

    G-13.mft UNCTION Coin channels The coin validator has 32 "memory slots" for coin acceptance which can be assigned up to 32 different coin types or tokens. These "memory slots" are termed coin channels. The acceptance band of a coin type/token is allocated to a coin channel and the coin type/token is accepted in that channel.

  • Page 22: Accepted Coin Sensor

    G-13.mft UNCTION Accepted coin sensor The Casino variant cannot utilise the accepted coin sensor owing to the fast coin acceptance as opposed to the ECV standard variant and MDB model. This section is therefore divided into two sub-sections. ECV standard variant and MDB model...

  • Page 23: Transfer Of Coin Values By Means Of Coin Impulses Via Coin Signal Lines (Not With The Mdb Model)

    G-13.mft UNCTION Transfer of coin values by means of coin impulses via coin signal lines (not with the MDB model) By default every coin accepted by the coin validator passes on one impulse to the vending machine control on the coin signal line assigned to it. An impulse tells the vending machine control that a coin has been accepted.

  • Page 24: Controlling External Sorting Of Accepted Coins (Not With Casino Variant)

    The G-13.mft as an ECV model can also be set by the manufacturer so that the return signal line sends a sort signal to the machine via the 10-pole connecting cable.

  • Page 25: Do Not Accept Coin Types

    G-13.mft UNCTION Do not accept coin types If coins are to be no longer accepted for payment at the machine, either the entire coin acceptance process can be inhibited (common inhibit) or individual types, e.g. if there is no more change in an external payout device or a coin type is very frequently replaced by false coins.

  • Page 26: Mdb Model

    However, the machine can also inhibit only certain coin types. For details on how these functions are programmed please refer to "NAMA document MDB/ICP 2.0" or the NRI specification for the G-13.mft "G-13.mft MDB Communication Interface", which we will be pleased to place at your disposal on request.

  • Page 28: Starting Up In The Machine

    TARTING UP Starting up in the machine Install the ECV model of the G-13.mft in machines with an ECV interface and the MDB model in machines with an appropriate MDB interface. 1. Disconnect the vending machine from the mains supply.

  • Page 29: Starting Up At The Tester (Not With The Mdb Model)

    TARTING UP Starting up at the tester (not with the MDB model) The functions of the G-13.mft as ECV model can be tested using NRI tester G-19.0594 (ordering code: 11801). For details of how to connect the G-13.mft to the tester and operate the tester, please refer to the separate operating instructions for the tester.

  • Page 30: Device Environment For Mdb Model

    Fig. 5b: Connecting the MDB model to a PC Connection to a Palm Handheld With a Palm Handheld and NRI software PalmEMP2 the G-13.mft can be directly configured locally inside the machine. You receive a connecting cable enclosed with the PalmEMP2 program. For details of how to connect the Palm Handheld, install and operate PalmEMP2, please refer to the separate operating instructions "PalmEMP2 –...

  • Page 31: Operation

    G-13.mft PERATION Operation This chapter describes how to inhibit and teach coin types using the switching block. Inhibit coin channels The first six DIL switches S1–S6 on the switching block at the rear of the coin validator can be assigned individual coin types or coin groups (or their coin channels).
  • Page 32 G-13.mft PERATION Example – Inhibit a currency as coin group (the coin validator must only accept euros and no longer the British currency) With this setting the coin validator only accepts euros. Example – Activate narrow acceptance bands/coin channels as coin group (the coin validator must accept the 1-euro coin and the British 1-pound coin in the narrow acceptance band and not in the normal one, i.e.

  • Page 33: Teach Mode

    G-13.mft PERATION Teach mode Coin channels can also be taught directly without configuration software via the switching block on the coin validator, i.e. a coin channel is assigned a coin type or even a token. This is also possible if the coin validator is installed in a vending machine.
  • Page 34 G-13.mft PERATION Now you can save the measured values generated by the inserted coins in either a normal (a) or a wide (b) acceptance band. By extending the acceptance band, the rejection of genuine coins is reduced but at the same time the acceptance of false coins may be increased.
