1 Introduction
General information about these instructions
These operating instructions describe the design and operation of the ECV
and MDB models of electronic coin validator G- 3.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.
To make it easier for you to navigate within these instructions and to operate
the device, the following markings were used within the text:
•Safety instructions, which have to be taken note of in order to
protect operators and equipment, have been written in bold and given
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 given sequential numbers ( ., 2., 3.
etc.).
To configure and test the coin validator reference is made to the separate
operating instructions of the NRI PC software "WinEMP" and the NRI Palm
Handheld software "PalmEMP" (refer also to Chap. 7 "What functions can
be set using WinEMP/PalmEMP"):
• WinEMP – The configuration and diagnostics program for NRI coin
validators, operating instructions for the G- 3.mft
• PalmEMP2 – Operating instructions for configuration of coin validator
G- 3.mft
• Tester G- 9.0594/4 for G- 3 ECVs
If these instructions are not available to you, they can be
downloaded at any time from the NRI homepage (www.nri.de) in a
compressed PD format.

General information about the coin validator G-13.mft
The electronic coin validator G- 3.mft (Multi-Frequency-Technology) in
standardized 3 /2" format is based on the tried and tested features of the
G- 3.6000. Due to its modular and compact design, the G- 3.mft -is ideally
suited for amusement, vending and service machines.
The Multi-Frequency-Technolo y is new in the G- 3.mft. It provides
more flexibility for the measuring sensors, multiple scanning of the coins
inserted for optimum material recognition and evaluation of 24 measuring
parameters for reliable acceptance of genuine coins and separating out of
false coins. Thanks to the coin validator’s Flash-Technolo y software
downloads to adapt the measuring technology, coin data and control
software can be executed quickly and simply. The G- 3.mft has 32 coin
channels which are managed in a single memory block.
To be able to react as quickly as possible to new false coins and to enable
you to make your individual adjustments, in future the coin validator will be
connected to a PC programming station which is made up of the configuration
and diagnostics software WinEMP including card reader and the tester
G- 9.0594/4 (for ECVs) or G-55.0338 (for MDB). With the aid of the Palm
Handheld software "PalmEMP2" you can configure the coin validator directly
at the machine independently of the PC.
Old currency and new coins being added to a currency which have not been
taken into consideration at the manufacturer can be programmed in the
optional teach mode directly at the coin validator by inserting coins.
Advanta es
• Acceptance speed of 2 coins per second
(Casino model: 6 coins/sec.)
• 32 coin channels which can be inhibited individually or in groups
• Teach mode for 6 coin channels
• Operating and manipulation safety thanks to optical accepted coin
sensor and sorting control in coin outlet area
• Interface for connection to a programming station which makes
immediate reaction to the use of false coins possible
• Multi-Frequency-Technology for reliable coin recognition
• Flash-Technology for uncomplicated and time saving software
adjustments

Models
The G- 3.mft is available as an ECV (electronic coin validator) and as an
MDB (multi drop bus) model. A totalizer model is being developed. Of the
ECV model you have at your disposal the proven standard and casino
variant.
ECV model
The G- 3.mft as an ECV model communicates with the machine via a
parallel interface. It is used whenever coins inserted into a machine have to
be checked for certain coin properties.
Coins inserted into the coin validator pass inductive and optical sensors
which check the coins and there they generate individual measurement
values. Due to a special construction and arrangement of the sensors, each
coin is checked for its material properties and dimension. If the measurements
of the coins inserted agree with the values stored in the coin validator, the
coin is accepted for payment; if they do not agree, they are rejected.
The ECV model is available as
• Standard ECV and
• Casino variant for fast coin acceptance (e.g. gambling machines)
MDB model
The G- 3.mft as an MDB model communicates with the machine, as
opposed to the ECV, via a serial MDB interface. The machine operates as
a master and the G- 3.mft as a slave. The G- 3.mft MDB is used whenever
coins inserted in a machine have to be checked for certain coin properties,
exactly like the ECV model.
The measuring and validating principle is the same as that of the ECV model.

Top and Front entry
Both models of the G- 3.mft are available with top or front entry. The
G- 3.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.
