INSTALLATION
ALWAYS POWER DOWN MACHINE PRIOR TO INSTALLATION.
The cashbox does not lock to the chassis. When you remove the unit from the container or when
the unit is not installed in the machine, you must never carry the bill acceptor by the handle of
the cashbox. The cashbox may release causing the rest of the unit to fall and damage the chassis.
Installing The Chassis
•A custom connector will come screwed to the back of the
Chassis (see Interface Manual 002850103 for more details).
Connect the adapter from the chassis to the machine. Always
dress all harness wires to avoid interference with any equip-
ment operation.
Note: If you have a custom set-up. You will need to contact our
technical support group for assistance.
•Once the connections are made, you will need to line up
the chassis mounting holes with the machine mounting holes.
There are 12 mounting holes. Three on each side of the chassis,
four located on the back and two on the bottom. M4 screws
must be used. Screws must not exceed a 6mm depth through the
mounting plate. Otherwise they may interfere with the
removable cashbox.
Installing The Cashbox
•With the chassis mounted securely to the machine, you may
now insert the cashbox into the chassis. The cashbox has slots
on both sides that will guide it into the chassis. When you insert
the cashbox, you will feel some resistance from the two springs
inside the chassis. Make sure to insert the cashbox all the way in
so that the rear of the cashbox is flush against the chassis wall.

INSTALLATION
Removing the Cashbox
Inserting And Removing the Acceptor Module
•Insert the Acceptor Module so that the release lever locks into place.
•To remove the unit, pull upwards on the release lever
located on the front of the Acceptor Module and pull
away from the chassis.
•When the bill acceptor is installed in a machine, you just need to grab the yellow strap on the
cashbox and pull firmly to release it. The
cashbox does not lock on to the Chassis.
• To remove the cashbox when the unit is not
installed, grab on to the yellow handle and
place your thumb on the chassis were indicated
in this diagram. Placing your thumb at this
location will give you sufficient leverage to
remove the cashbox.

The cashbox may be fitted with either one or two security locks. The product is designed to
accept locks from a range of manufacturers including: -
Medeco
Kaba
Abiloy
VSR
Miwa
Duo
Standard 5/8" and 1-1/8" formats are supported. There is a significant variety of lock designs,
and spacer washers may be required for some lock types. Two locking hasps are shipped with
every cashbox. Contact MEI for cashbox lock specifications.
Locks vary greatly in price, security, keying policies, etc. The customer is responsible for selecting
a lock with performance that is fit for the intended purpose. MEI does not test or endorse any
specific brand of lock for security characteristics.
When only one lock is used, the remaining blank hole does not give access to the contents of the
cashbox. However, some regulatory authorities may require a blanking plug be fitted. Contact
MEI for assistance in obtaining a suitable plug.
When two locks are installed, they must rotate in opposite directions. See the figure below.

HARNESSINGAND CONNECTORS
Cashflow SC66 bill acceptors with an EBDS Interface will have a harness that terminates with a
12 Pin Connector.
Note: Some SC66 units will come with harness termination connectors that are “OEM-Specific.” Please refer to the
host machine manual for pinout and connector information.

Periodic maintenance can improve the performance and extend the working life of a bill accep-
tor. Additional attention may be required if the bill acceptor becomes inoperable due to a
jammed object or acceptance rates fall below normal.
Cleaning And Clearing The Bill Path and Sensor Area.
Note: You must remove the Acceptor Module from the chassis to open the front sensor area. Forcing the bill path open
without removing the Acceptor Module from the chassis will damage the connector board located at the rear of the
Acceptor Module.
•Release the Acceptor Module from its normal operating position.
•Open the Acceptor Module unit by pressing up on the yellow cap.
•Clear the bill path area of any foreign objects.
•Clean bill path and sensor areas as needed.
For stubborn dirt, a small amount of mild non-abrasive soap may be applied to a damp cloth.
Make sure no streaks or residual from the cleaning product remain on the bill path.
Note: Never use a petroleum-based product to clean this device! Petroleum based products will damage the bill
path.
Calibration
The SC66 series bill acceptor does not require any calibration in the field. Thus, the unit has no
switch settings or calibration mode that allows a user to perform a calibration. If, for any reason,
the unit requires calibration, it may only be done by one of our trained technicians.

MAINTENANCE
Diagnostic Codes
The chart below indicates the 15 color-coded combinations of diagnostic LEDs on the bill
acceptor. For each color, there is a solid indicator and four flashing combinations. If multiple
failure conditions occur, the most severe condition will be displayed.
Red conditions - Hard Fault. One of the bill acceptor components needs to be replaced.
Yellow condtions - Soft Fault The operator can correct the issue at the machine.
Green conditions - No Fault No problem with the bill acceptor.
Note: By opening the machine door, you will disable the primary interface. The 10-second delay allows you to see
a normal condition on the unit prior to the MMI display update.
