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.

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.

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).

Fig. 2 Connection between a coin operated machine (controller), an
installed coin selector and a PC
Every coin selector is fully tested and configured at the factory
and is supplied ready for installation. Please make note of the
factory settings, or alternatively, read and store them on the
hard disk before making changes. The settings could be stored
with a file name incorporating the serial number. The coin
selector must be “read out” first and this procedure is
explained in the wheasy 5 manual.
Please also note the information on the coin selector label.
It is important that the coin selector be located in an upright
position when programming. Similarly, the bottom surface of
the coin selector needs to be horizontal. This can often be
achieved by mounting the coin selector in the same manner
that it is mounted in the coin-operated machine. Alternatively,
wh Münzprüfer can provide you with a purpose designed stand
T 500.
The following sections detail each WindowsTM software wheasy 5 related
function of the coin selector. Each function has its own chapter as listed
in the table of contents in this manual.

2.3. Programming of Coins
There are a variety of ways in which the coin acceptance of the
EMP 500 v7 /CLB may be programmed.
The coin selector can “learn” new coin parameters, including individual
tolerance requirements, with the help of the Calibration Function.
Calibration is carried out either using the PC based wheasy 5 software or

directly in the coin-operated machine using the Teachmode Function
(see On site programming).
Yet another alternative would be to transfer a previously prepared
complete coin parameter data set from the PC to the coin selector. This is
commonly referred to as the Cloning Function. This method is far less
involved than calibration because it dispenses with the time consuming
task of inserting coins. A pre-requisite however is that an approved and
appropriate coin parameter data set is available. These may be acquired
via the internet from WH Münzprüfer ([e-mail]).
2.3.1. Calibration
2.3.1.1. Calibration using wheasy 5
Under the Edit pull down menu is the function “Calibration”. Pressing the
<F4> key can also directly access this window. This will bring up the
following window:
Fig. 4 Window Calibration
At the top left side a coin channel to be calibrated is selected. The coin
value and currency code for the selected channel is displayed provided
that it has been written to the file as being programmed to that channel.
This is shown next to the channel number.
Not only the coin channel may be chosen but also the calibration mode.
The calibration mode is activated for the chosen coin channel from the
data set, it may be modified at any time until the end of the calibration.
The calibration mode “fix” is intended for use with coins and coin channels
for which preset tolerance parameters are available and calibration mode
“fix” is also preset. As a general rule, “fix” provides the best results when
such information is already available.
The coin tolerances are automatically adjusted to the test coin set when
“narrow”, “average” or “broad” are chosen. This makes them particularly
appropriate for the calibration of new coins or tokens in the absence of
coin data sets.
Each of the calibration ranges approximates coin acceptance as follows:
narrow approx. 95%,
average approx. 98%,
broad approx. 99%.

Technical Manual EMP 500 v7 /CLB WH Münzprüfer Dietmar Trenner GmbH, Germany
version 2.7
page 14/62 subject to technical modification EMP 500 v7 /CLB
Obviously, the actual acceptance rate in a vending application may vary
from the figures above. The level of variation relates directly to just how
the coin set used for calibration is typical of the coins currently in
circulation. Therefore, a mixture of older and newer coins must be used
for this procedure. The coins must have no damages.
The number of inserted coins as well as the overall number of coins
required is shown in the calibration window. The total number of required
coins is determined by the data file. Calibration automatically ends once
the required number of coins has been inserted and the procedure may
now be finished or another coin channel selected for calibration.
If the checkbox “Ignore Number” is activated the calibration is no longer
automatically finished once the pre-set number of coins is reached. It is
possible to insert as many coins as desired. Following this, an additional
channel can be chosen or the calibration procedure can be finished with
the push bottom “close”.
For the creation of a new coin or token channel, please select an unused
channel from the existing 16 and assign a value and an output line. To do
this, please refer to chapter 2.6 of this document. For the assignment of
coin blocking DIP switches to this channel please refer to chapter 2.5. To
accept the new coins or tokens of the new channel during testing with the
polling function of wheasy 5 mark the respective checkbox (please see
“Test” - “Coin Control”).
2.3.1.2. Calibration Using the Teach Mode Function (Option /T)
The coin selector can be delivered with an optional teach mode function
(on site programming). The teach mode can be set up for a maximum of
14 channels at the factory. No PC is required for the teach mode, since
the necessary software is built into the coin selector.
The teach mode is activated by setting the number 8 switch on the left
side of the DIP switches to “ON”. The number 7 switch of the same DIP
switch block is used to set the acceptance tolerance to “broad” or
“narrow”. The “ON” setting selects a narrow tolerance.
To start the calibration it is necessary to select a channel to be calibrated
by setting one channel switch to “ON”. The left DIP switch on the left side
corresponds to channel 1 and right DIP switch on the right side
corresponds to channel 16.
The coin channel must be chosen after activation of the teach mode switch
8. The advantage is that it is not necessary to set all DIP switches to “OFF”
first before programming a particular channel.
Channels 7 and 8 cannot be calibrated with the teach mode because the
DIP switches 7 and 8 are used to set the acceptance tolerance and to
activate teach mode respectively.
Only 15 blocking switches are available on those coin selectors
that have been factory set with the teach mode. The coin
selector will not accept any coins while it is in the teach mode.
Figure 5 below shows the example of setting up channel 15 for calibration
with narrow acceptance tolerances.

WH Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 500 v7 /CLB
version 2.7
EMP 500 v7 /CLB subject to technical modification page 15/62
Fig. 5 Example DIP switch settings for teaching channel 15 with
narrow tolerances.
The following procedure is for coin selectors with activated teach mode
(factory setting):
1. The coin selector is configured, so that only coin channel 15 and 16
(i.e. coin output lines 5 and 6) may be used for teaching.
2. The teach mode is activated via blocking switch no. 8 (ON).
3. If blocking switch no. 7is activated additionally (ON), teaching is
effected using narrow tolerances.
4. The blocking switches 15 and 16 are used to teach coin channels
15 and 16. The switches have to be set to the OFF position when
activating the teach mode, otherwise the coin selector software blocks
the two channels for the teach mode.
5. If any coin blocking switches are activated (ON) for channels which
are not released for the teach mode, the coin selector magnet will
operate briefly three times to indicate an incorrect operation.
6. To program the coin selector with the teach mode a minimum of 10
coins or tokens must be inserted. When the requisite number of
coins have been inserted and the teaching procedure has been
completed (by setting the blocking switch no. 15 or 16 back to the
OFF position), the coin selector solenoid will operate briefly and once
only.
7. Should the coin selector establish an overlapping of the newly
programmed coin with a coin / token already programmed, then the
coin selector solenoid will operate briefly twice and no new data will
be stored in the memory of the selector. If it is not possible to program
the new coin / token with the setting “wide” (inhibit switch number 7
is on OFF), then it may be possible to program it in the narrow setting
(inhibit switch 7 is ON).
8. Insufficient coins being inserted will result in the solenoid not
operating and no new data will be stored into the memory of the
selector.
9. The teach mode is deactivated via blocking switch no. 8 (OFF).
When the teach mode is deactivated, all blocking switches may then
be used for individual coin blocking with the exception of blocking
switch no. 8.

2.3.2. Cloning (Programming without coins)
Cloning is the fastest way in which to program a coin set. Using this
method, coin parameter sets are transferred into the coin selector from
the PC. It is also possible to transfer a coin parameter set from one coin
selector to another thereby giving it nearly identical acceptance and reject
rates. It does not make any difference whether the cloning data set is a
wh original data set or whether it was copied from a coin selector and
stored in the PC.
As a prerequisite to cloning, it is necessary for the coin measuring system
of the originating coin selector to be the same as the measuring system
of the target coin selector. wheasy 5 automatically compares the
measuring configuration of the attached coin selector with the measuring
configuration of the coin selector that produced the coin parameter set.
Cloning is only accomplished if the two systems are indeed the same.
Other data sets are available from wh Münzprüfer if wheasy 5 does not
allow cloning because of a mismatch in the measuring system
characteristics.
Cloning can begin once the PC has been loaded with the cloning data set
and when the coin selector has been connected. This function can be
accessed by selecting “EMP cloning” from the “Data” pull down menu or
directly by clicking

The following window opens up after selecting the function “EMP Cloning”:
Fig. 6 Window “Clone EMP”
In certain situations it is possible to selectively clone individual channels.
This can be carried out provided that the loaded data file is identical with
the name of the file loaded from the coin selector. This we refer to as
selective cloning.

Selective cloning is useful when the parameters for a specific coin are to
be changed, or maybe a token is to be added without overwriting the fine
tuning of other coins. With selective cloning all coin channels with
activated coin boxes will be cloned.
The actual cloning process takes about 10 seconds after the OK button
has been pressed (at 38400 Baud).
2.4. Coin Selector Output Signals
There are 2 parallel coin output lines on the EMP 500 v7 /CLB. They can
be freely assigned in any combination to the 16 master channels. This
means that each coin channel can have multiple output lines and that the
number of pulses can be freely configured for each coin channel. One and
the same output line or a combination of the output lines can be assigned
to several coin channels. The 16 slave channels always have the same
output line(s) as the associated master channel.
After accepting a coin or token the coin selector releases the
corresponding number of pulses on the respective output line. The pulse
width and the pulse pause of the coin output signal can be programmed
in steps of 1 millisecond, between 1 millisecond and 65 milliseconds. The
output lines are normally open. A pulse is signalled by making the output
transistor conducting.
The pulse length can be programmed using wheasy 5 under
“Configuration” – “Interfaces” and tab “Receipt”.
The programming of the output lines for all coin channels 1 to 16 can be
done via the menu point “Configuration” – “Interface” and tab “Output
Lines” (see figure 7).
If no output line is assigned to a coin channel and a coin is
accepted, the coin selector does not release a coin signal via
the parallel interface. As an alternative a credit signal can be
released as an inventory pulse. The assignment of inventory
pulses is done on the tab “Output Lines”.

Fig. 7 Register tab “Output Lines”
The figure shows the 16 coin channels (vertically) and the 8 output lines
(horizontally). Please note that the EMP 500 v7 uses two output lines
only.
The number of coin signals per output channel can be programmed in the
column “Pulse”.
In the lines “Inventory Pulse 1” and “Inventory Pulse 2” the inventory
pulses can be assigned to one of the output lines.
In the lines “Coin on a String” and “Coin Jam” the alarm signals are
assigned to one of the output lines. The alarm signals can be distinguished
by the controller by a different pulse length.
In the line “Polarity inverted” the active state of the output lines are to be
selected (active high or active low). Inverted means, the output transistor
is normally conducting and is not conducting to signal a pulse. “Not
Inverted” means there is no current through the output during idle times
but for signaling coins there is current for the length of the pulse through
the output.
2.4.1. Inventory Pulses (Option /I)
The EMP 500 v7 /CLB offers 2 different inventory pulses optionally. These
inventory pulses are intended for the counting and logging of accepted
coins. The values of the two inventory pulses can be defined under
“Configuration” - “Currencies and Coins” (see chapter 2.6. Currencies and
Coins). This menu also allows to activate the inventory pulses and to

version 2.7
EMP 500 v7 /CLB subject to technical modification page 19/62
allocate inventory pulse 1 and inventory pulse 2 to the 16 coin channels.
The pulse length and pulse pause are individually programmable in the
range of 1 to 255 milliseconds. The factory default is an impulse duty
factor of 50 milliseconds /50 milliseconds.
The EMP 500 v7 /CLB can be delivered with two different
inventory pulses for both output lines (“Inventory Pulse 1” and
“Inventory Pulse 2”). The two inventory pulses can be
assigned to the coin channels with the programming software
wheasy 5. The advantage is that the number of inventory
pulses for the different coin values is reduced and therefore
the coin acceptance speed is increased. In contrary to the
standard coin pulses with the help of the inventory pulse coins
can be accepted even though the release of pulses for the
already accepted coin(s) is still in progress.
2.5. Coin Blocking
Coin blocking may be accomplished in various ways. One possibility is the
general blocking input line, which will block the coin selector from
accepting all coins. Secondly, it is possible is to block coins or groups of
coins individually through 16 DIP blocking switches on the coin selector.
The DIP blocking switches are accessible through a recess in the coin
selector cover.
2.5.1. General Blocking (Option /U)
Optionally the EMP 500 v7 /CLB has a potential-free infrared opto-coupler
at its disposal for the general blocking. The inhibit voltage depends on the
coin selector hardware and lies between 12 and 60 V AC/DC. It is standard
that the coin selector is blocked when the infrared opto-coupler is powered
up. This is known as “general blocking via low” for the coin selector
programming with wheasy 5. Alternatively the general blocking function
can be programmed so that the coin selector is blocked when the infrared
opto-coupler is not powered.
The signal polarity of the general blocking is programmable with wheasy 5
under the menu selection “Configuration” – “Blocking” and check box
“General Blocking by means of “0”” (See figure 8).

blocking with wheasy 5
2.5.2. Individual Coin Blocking via DIP switches
The coin selector has 16 DIP switches for individual coin blocking. Blocking
is not active, that is, the coin will be accepted when the switch is in the
“OFF” position. A coin will be rejected when the switch is “ON”.
The 16 switches can be freely assigned to the 32 coin channels. Each coin
channel can be associated with 16 switches. This configuration makes it
possible to block individual coins or, if multiple currencies are
programmed, it is possible to block a whole currency with one switch. For
example 12 individual coins can be assigned to the first 12 switches. Then
switch 13 to 16 can be used to block whole currencies. This optimal use
of the switches allows the easy selection of one currency or even multiple
currencies at the same time.
The following figure illustrates the assignment of blocking switches and
also the numeric identity of each switch.
Fig. 9 Blocking assignment
The lower switch position is the “Off“ position. The upper switch position
denotes “ON”. In this example all coins assigned to switch 7, 8 and 15 are
blocked
The programming of the blocking switches is done with wheasy 5 and is
explained in the wheasy 5 technical manual (see also figure 8).
