About This Handbook
The CashFlow® 690 Series changegiver fitted to your vending
machine incorporates the very latest developments in
automatic payment systems technology. It provides high
standards of security and reliability that have become the
hallmark of MEI products.
This Operator’s Handbook compliments your product training
and provides you with the information you need to support the
day-to-day use of your CashFlow® 690 Series changegiver.
The Handbook has five sections:
Changegiver Overview – provides an overview of how the
changegiver is configured and information about the modules
with which you will be concerned.
Service Procedures – explains how to carry out servicing
procedures such as changing prices.
Cleaning – describes the routine cleaning requirements.
Troubleshooting – explains how problems are automatically
identified and tells you what corrective action you can take.
Changegiver Replacement – explains how to replace a faulty
changegiver with a new one.
There are three variations of the CashFlow® 690 Series
changegiver:
q 690 Executive/MDB/BDV
q 690 MDB 1 price
q 690 MDB 4 price
You can find which version is fitted to your vending machine
looking at the display just above the keypad (see pages 1 and
2). When the changegiver is switched on ready to use,
included in the string of displayed text you will see the product
version details.

Coin Tube Cassette
The function of the coin tube cassette is to provide a supply of
coins for dispensing as change, thus enabling coins of high
denomination to be accepted.
Acceptor/Separator
The acceptor and separator are assembled as one unit.
The acceptor has sensors that compare the characteristics of
each coin or token inserted with those of a pre-programmed
set.
If they conform to the pre-programmed set, they are accepted.
They then pass, via the separator, into the change tubes or
into the cashbox.
If they do not conform to the pre-programmed coin set, they
are rejected and pass through a reject chute inside the
changegiver and then into the return cup of the vending
machine.
Dispenser
The dispenser dispenses coins being returned as change.

Cleaning
This section describes the cleaning procedures you are advised
to carry out on a regular basis.
Requirements
Apart from general cleaning near the changegiver, the coin
pathways, dispenser arms and guides must also be kept clean.
You must do this on a regular basis as a build-up of dirt can
cause the changegiver to malfunction.
The frequency with which you do this depends on the
operating environment. Recommended frequencies are:
q Clean office environment - every three months
q Shop floor environment – every month
The need for cleaning is also indicated when coins are
increasingly not accepted.
Safety
BEFORE YOU BEGIN, SWITCH OFF THE POWER SUPPLY TO
THE VENDING MACHINE
What to Use
Use only a soft damp cloth or a soft brush.
DO NOT USE SOLVENTS OR ABRASIVES

Replacing a Changegiver
This section tells you how to replace a changegiver.
Before You Begin
1 TURN OFF THE POWER SUPPLY TO THE VENDING
MACHINE
2 Check the voltage of the replacement changegiver. Be sure
that it is compatible with the voltage supplied by the
vending machine. You will find the information you need
on the label attached to the side of the changegiver

Fixing Arrangements
The changegiver has three fixing keyholes as shown below.
The vending machine is fitted with three screws in matching
locations. Alternatively, there may be two location studs and
one retaining screw, or a similar arrangement.

Installing
1 Locate the changegiver on the screws or studs fitted to
the vending machine, making sure it is flat against the
vending machine panel
2 Retighten the upper right-hand retaining screw
Installation Checks
1 Check that when the changegiver
is idle there is a gap (dimension x)
between the lever on the vending
machine and the lever on the
changegiver
2 Check the alignment of the coin
chutes. Insert two coins of each
denomination into the vending
machine and check that they
cleanly enter the changegiver
acceptor and exit from the
changegiver into the cash return
cup
Connecting
1 Plug in the changegiver power
lead to the vending machine
(and also any comms or display
cable if applicable – see below)
The changegiver is supplied
fitted with up to six cables.
One of the end connectors will
match the power socket on the vending machine

jack, there will be cables attached to the changegiver with
matching connectors which you must also plug in
2 Tuck the unused cables away tidily. Make sure they will
not be trapped when the changegiver lever is pressed or
when the vending machine door is closed
3 Switch on the power to the vending machine
4 Check that after an initial multi-colour flashing sequence
the LED on the changegiver keypad settles to green. This
will indicate the changegiver is functioning correctly and
the installation is then complete
If the green LED does not come on, or is amber, refer to
Troubleshooting on page 19.
