Troubleshooting Error Codes; Error Codes - Stoelting O411 Operator's Manual

5.1 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
1 Soft
2 High Torque
3 Extended Run Time
4 Clean
5 Barrel Sensor
6 Hopper Sensor
7 Drive Motor
8 Cab Sensor
9 High Pressure Cutout
10 Auxiliary Sensor
11 Low Temperature
To return the machine to normal operation, any error
causing condition must be corrected and the Freezing
Cylinder Off-On switch must be placed in the Off position
and back in the On position before the affected side of
the machine will return to normal operation.
5.2 TROUBLESHOOTING - ERROR CODES
Error Code 1 - Soft Error
The Soft Error (E1) is an internal control board error
that is logged for future analysis. The refrigeration
is never stopped and the machine will continue
to operate normally.
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 125% of the preset CutOut
amp setting for 10 or more seconds. This may
be due to the product consistency adjustment
being set too high. Place the Main Power OFF/ON
switch in the OFF position, wait until the product
in the freezing cylinder thaws to a reasonably soft
consistency and return the Main Power switch to
the ON position. Follow the steps in section 3 to
reduce product consistency by a few levels. If the
error persists, contact your authorized Stoelting
Distributor for further assistance.
SECTION 5
TROUBLESHOOTING
Error Code 3 - Run Time
Error Code 4 - Clean
25
The Run Time Error (E3) occurs when the
compressor runs continuously for 20 minutes
without the product reaching consistency in
"Serve Mode" or if the product does not reach
proper temperature in "Sleep 2 Mode". This
error is generally caused by very low mix levels
in the machine's mix container or from product
breakdown. Another common cause results from
a restriction preventing mix from entering the
freezing cylinder. Check the mix in the cabinet. If
the level mix is low, add mix. If there is a possibility
that the mix is broken down, clean and sanitize the
machine and replace the mix with fresh product.
Ice crystals in the liquid mix container can clog the
mix inlet system and prevent mix from entering
the freezing cylinder. Thoroughly thaw mix per
manufacturer's recommendations. To check for
ice crystals, pour a small amount of product in the
mix container through a clean and sanitized sieve
or strainer. If ice crystals are in the mix, check
the temperature of the walk-in cooler where the
mix is stored or the temperature of the machine's
cabinet.
Check the condition of the neoprene hose running
through the mix pump head. If it shows signs of
wear, rotate or replace it as outlined in Section
3.
In air cooled machines, the Run Time Error may
indicate that airfl ow within the machine has
reduced or stopped. Check the sides and top
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.
If the machine is left in the Clean Mode for more
than 20 minutes, the control panel will display a
Clean Error (Error 04). 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". The control will attempt to
restart itself after 5 minutes. The display will then
fl ash and read Restart. To immediately clear the
Clean Error, place the Main Power Off-On switch
in the Off position and back in the On position.
After restarting the machine, a refrigeration cycle
will begin. This protects the product in case the
clean button was pressed by mistake.
