The coin changer attempts to maintain a certain quantity
of coins in the coin tubes. This quantity is called the "fl oat"
(also known as PAR setting). The ideal fl oat is to have
just enough coins needed to provide change to every
customer between maintenance visits.

FLOAT OPERATION

During maintenance, use the fl oat operation to dispense or
insert coins to bring the coin level to the fl oat setting. The
factory default fl oat setting is full tubes (the fl oat operation
will request coins to be inserted until each coin tube is full)

NOTE

Refer to the MEI Cashfl ow operation guide for in-
formation on how to change the fl oat value.

A. Press the yellow button on the coin manager to

access the menu.
B. Press the A button to select FLOAT
C. After two seconds, the changer dispenses any

excess coins.
D. If a coin tube is low , the display shows the quantity

needed to achieve the fl oat value. Add coins or

press Skip.
E. Press the Finish button.

TROUBLESHOOTING

4.1 OUT OF ORDER

If the vending interface shows an out of order screen,
complete the following checks before contacting a service
technician.

CUP LEVELS

Make sure there is a minimum of three tubes full of cups.
Insert a maximum of 30 cups into each tube. When insert­ing, pull them apart slightly so they are not stuck together.
Discard any damaged cups.

MIX LEVELS

Make sure the hoppers are at least 3/4 full of liquid mix.
Add mix if necessary.

CAROUSEL DOOR

Make sure there are no objects in the carousel door and
remove them if necessary.

CUP HOLDER ASSEMBLIES

Make sure the thumb screws on the cup holder assemblies
are tight. Tighten as necessary.

INTELLITEC2™ ERROR

Refer to Section 4.2 for troubleshooting error codes on
the IntelliTec2™ control.

4.2 INTELLITEC2™ ERROR CODES

When the machine experiences a problem, one of the
following error codes will be displayed on the control
panel. Each error code directs you to the system location
of the malfunction.

ERROR CODE MALFUNCTION
2 High Torque
3 Run Time
4 Clean
5 Freezing Cylinder Sensor
6 Hopper Sensor (single hopper machines)
7 Drive Motor
8 Cab Sensor
9 High Pressure Cutout
10 Auxiliary Sensor
11 Prime (cab units only)
12 Left Hopper Sensor
13 Right Hopper Sensor
21 Spigot Open Time
To return the machine to normal operation, any error

causing condition must be corrected and the power to
the affected freezing cylinder must be cycled. Turn the
power to the freezing cylinder off then back on using the
On/Off button of the affected freezing cylinder.

4.3 INTELLITEC2™ ERROR CODE
TROUBLESHOOTING

Error Code 2 - High Torque

If the control panel displays a High Torque Error

(E2), the controller has sensed that the drive motor

is running at a high load for 10 or more seconds.

This may be due to the product consistency

adjustment being set too high. Press the On/Off

button for the cylinder to turn it off, wait until the

product in the freezing cylinder thaws and then

turn the cylinder back on. If the error persists,

contact your Authorized Stoelting Distributor for

further assistance.

Error Code 3 - Run Time

The Run Time Error (E3) occurs when the

compressor runs continuously for an extended

period. This error is generally caused by very

low mix levels in the hopper or from product

breakdown. Another common cause results from

a restriction preventing mix from entering the

freezing cylinder. Check the mix in the hopper.

If the level mix is low, add mix. If there is a

possibility that the mix has broken down, clean

and sanitize the machine and replace the mix

with fresh product.
Ice crystals in the hopper can clog the mix inlet

system and prevent mix from entering the freezing

cylinder. Thoroughly thaw mix per manufacturer’s

recommendations. T o check for ice crystals, pour

a small amount of product from the mix container

through a clean and sanitized sieve or strainer.

If ice crystals are in the mix, check temperature

of the walk-in cooler where the mix is stored.
In air cooled machines, the Run Time Error

may indicate that airfl ow within the machine

has reduced or stopped. Check the sides of the

machine for anything that would restrict airfl ow.
If the error persists after attempting to clear it,

contact your Authorized Stoelting Distributor for

further assistance.

Error Code 4 - Clean

If the machine is left in the Clean Mode for more

than 20 minutes, the control panel will display a

Clean Error (E4). This condition does not refl ect a

problem with the machine itself. The Clean Error

has been programmed into the controller as a

safeguard to protect the machine from potential

damage caused by the machine being accidentally

left in "Clean Mode". To clear the Clean Error,

press the On/Off button for the cylinder to turn if

off then back on.

Owner’s Manual #513698 Rev.1 13 AUTOVEND Model Machines

Error Code 5 - Freezing Cylinder Sensor

The Freezing Cylinder Sensor Error (E5) indicates

a failure of the barrel sensor or if the sensor is
out of range. If the control panel displays an E5,
press the On/Off button for the cylinder to turn
if off then back on. If the error persists, contact
your Authorized Stoelting Distributor for further
assistance.

NOTE

When the machine encounters a Freezing Cylinder
Sensor Error, the machine will continue to run using
preset timers. This mode will allow the operator to
continue serving product until the machine can be
serviced.

Error Code 7 - Drive Motor

If the control panel displays a Drive Motor Error

(E7), the control does not sense current coming
from the drive motor. Press the On/Off button
for the cylinder to turn if off then back on. If the
error persists, contact your Authorized Stoelting
Distributor for further assistance.

Error Code 8 - Cab Sensor

A Cab Sensor Error (E8) will not occur on the

machine.

Error Code 9 - High Pressure Cutout

High Pressure Cutout Errors (E9) are usually

caused by a dirty or ineffi cient condenser. If the
control panel displays an E9 on an air cooled
machine, check for proper air clearance around
the machine.

If the error persists, contact your Authorized

Stoelting Distributor for further assistance.

Error Code 10 - Auxiliary Sensor

An Auxiliary Temperature Sensor Error (E10)

occurs if the temperature sensor on the control

board fails. Press the On/Off button for the cylinder

to turn if off then back on. If the error persists,

contact your Authorized Stoelting Distributor for

further assistance

Error Code 12 - Left Hopper Sensor

The Left Hopper Sensor Error (E12) indicates

a failure of the hopper sensor or if the sensor is

out of range. If the control panel displays an E12,

press the On/Off button for the cylinder to turn

if off then back on. If the error persists, contact

your Authorized Stoelting Distributor for further

assistance.

Error Code 13 - Right Hopper Sensor

The Right Hopper Sensor Error (E13) indicates

a failure of the hopper sensor or if the sensor is

out of range. If the control panel displays an E12,

press the On/Off button for the cylinder to turn

if off then back on. If the error persists, contact

your Authorized Stoelting Distributor for further

assistance.

Error Code 21 - Spigot Open Time

The Spigot Open Time Error (E21) indicates a

failure of the spigot switch. If the control senses

the spigot is open continuously for 10 minutes, the

machine will go into Sleep 3 mode. If the control

panel displays an E21, press the On/Off button

for the cylinder to turn if off then back on. If the

error persists, contact your Authorized Stoelting

Distributor for further assistance.
