1. Introduction
The EMP 500 v7 /CLB offers multiple payment methods in one device. The
unit accepts coins and cashless payments. Developed to be more flexible
and to make e.g. laundrettes more convenient for users and operators.
The solution is supported by Android and IOS applications for mobile
devices with Bluetooth technology and mobile network.
Payment at the machine can be done with the easy-to-use wh
Münzprüfer’s “cashless laundry” app and supports PayPal and credit card
payments. Alternatively, the payment can be carried out with coins or an
RFID-key.
The EMP 500 v7 /CLB coin selector enables the operator to increase the
number of accepted payment methods within the same device. It is
retrofittable to previous EMP 500 series. No modification of the machine
is required.
When retrofitting, mobile app payments allow flexible pricing. The price is
to be read from the display of the machine and then adjusted in the
payment screen of the app. Flexible payment with RFID-key is not
possible. Alternatively, a fixed pricing of the machine is possible. Here
both cashless options are possible, RFID and app payment with the wh
cashless app.
The electrical outputs of the EMP 500 v7 /CLB have been especially
designed to facilitate the substitution of mechanical coin selectors such as
W 2000, W 6000 and W 7000 and electronic coin selectors of the EMP 500
v5 and v7 series, ensuring that only with minimal technical amendments
are required. We offer a range of front plates to ensure that no alteration
of the front plate cut-out is required on the machine.
The coin selector has an operation voltage of 8 to 30 DC or 12 to 24 AC
and is fitted with switching outputs that –depending on version used –
can totally replace the micro switches or opto-couplers of the mechanical
coin selectors.
In addition, the EMP 500 v7 /CLB can be supplied with an integrated
totalizer function (EMP 500 v7 /CLB, interface 06). Via the serial
programming connector, the selector can be operated with the MDB or
the ccTalk protocol.
Compared to previous EMP 500 v5 models the EMP 500 v7 has a new
mechanical design. The new design is even more solid and offers a higher
security against vandalism.
The coin selector generation v7 offers a combined optical and inductive
measuring system. The measuring system consists of various light
barriers and coil alignments, which are located directly behind the coin
insert in the flap and in the main body. It ensures a high coin acceptance
rate and an optimum rejection of counterfeits.
The EMP 500 v7 /CLB is equipped with a sophisticated coin monitoring as
a security provision against manipulation. Thus the EMP 500 v7 /CLB is
the ideal choice for all machines even for applications with high
requirements in regards to counterfeits detection and security against
manipulation.

1.1. Technical Data
1.1.1. Interfaces of the EMP 500 v7 /CLB
The EMP 500 v7 /CLB has 32 in-built coin channels and has 2 output lines.
The coin output assignment to the output lines can be freely programmed.
In addition, the coin selector offers a serial interface with different
protocols. The serial interface can be used to connect a display to the coin
selector also.
The various interfaces are described in greater detail in the chapters, 2.4,
2.5, 3 and 4.

Serial Interfaces
•EMP 500 v7 /CLB IF:13
The programming connector of the coin selector supports the serial
Multi Drop Bus (MDB) protocol, the ccTalk protocol and the SCI (serial
communication interface). The serial interface can be used to drive a

display too. The hardware of the serial interface does not match the
ccTalk or MDB specification.
There are 32 available coin channels –16 master channels and 16 slave
channels. The slave channels can be freely linked to the master channels.
They always have the same coin value and the same coin outputs as the
master channels. In general, they are used for the wide and narrow
settings.
The electronic coin selector EMP 500 v7 /CLB series can be programmed
through the serial interface. The WindowsTM software wheasy 5 is
available for these procedures.
wh Münzprüfer maintains a policy of continuous research and
development and unconditionally reserves the right for
technical modifications with respect to the EMP 500 v7 /CLB
series coin selector and the wheasy 5 software.
The electronic coin selector EMP 500 v7 /CLB is available with the
following front plates:

2. Function of the Coin Selector
2.1. Introduction
This chapter gives directions for preparing the EMP 500 v7 /CLB for
programming. Please conform to all safety precautions before making
changes to the unit.
Please note that all settings / programming of our electronic coin selectors
may be carried out at the factory or by any authorised "wh Münzprüfer
Service Centre." For a list with contacts please see also our website
(www.whberlin.de).
Coin operated machines, as well as coin selectors are
dangerous electrical devices. Always follow proper safety
procedures when working with electrical devices. Please turn
the power off before making or removing connections or
otherwise performing work on the unit.
This manual assumes that the wheasy 5 programming manual and the
programming software are available and that the operator is familiar with
them. References here to wheasy 5 software, are only made relative to
its specific application to the particular coin selector and its functions.
To power up the EMP 500 v7 /CLB and the associated PC interface, we
strongly recommend our N 789 power supply for this purpose. The coin
selector is connected to the dongle (interface converter) with the cable
K 548 provided with the software to the N 789 power supply. The dongle
is connected to an available USB port. See figure 1.
As shown in figure 2, the coin selector may also be programmed whilst in
situ and powered by the vending machine. This procedure requires the
use of the cable K 548 (See figure 2).
