Error Code 5 - Freezing Cylinder Sensor
The Freezing Cylinder Sensor Error (E5) indicates
a failure of the barrel sensor or an extreme out of
range condition (< -34°F or > 99°F). If the control
panel displays an E5, place the Freezing Cylinder
Off-On switch Off and back On. If the control panel
still displays the error code, refer to the machine's
wiring diagram and the Temperature Sensor Chart
(Figure 7-1). Check each lead of the sensor to
ground for continuity. If continuity is found, replace
the sensor. To check the resistance of the sensor,
place a thermocouple on the suction line at the exit
of the freezing cylinder. Compare temperature and
sensor resistance with the table as reference. If
measured value does not coincide with a value on
the table (± 400 ohms), replace the sensor.
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 6 - Hopper Sensor (single hopper machines)
The Hopper Sensor Error (E6) will not occur on the
machine.
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. Turn the Freezing Cylinder
Off-On switch Off and back On. If the error returns,
use the machine's wiring diagram and check
connections at the IntelliTec control and at the
motor. An E7 may also be the result of a faulty drive
motor contactor.
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 inefficient condenser. If the
control panel displays an E9, place the Freezing
Cylinder Off-On switch in the Off position. Press
the High Pressure Cutout Reset switch (water-
cooled only) and place the Freezing Cylinder Off-
On switch back in the On position.
In air cooled condenser models, check the air filter
to make sure it is clean. Replace or clean the filter
as required. Check for proper air clearance around
the machine. Refer to the Section 2 - Installation
Instructions for clearances. Check the condenser
for blockage, and be sure condenser fan is
functioning.
On water cooled condenser models, check for
proper water flow through the condenser coil.
After the cause of the error is determined and
corrected, turn the Freezing Cylinder Off-On switch
Off and back On.
Error Code 10 - Auxiliary Sensor
An Auxiliary Temperature Sensor Error (R10)
occurs if the temperature sensor on the control
board fails. Turn the Freezing Cylinder Off-On
switch Off and back On.
Error Code 11 - Low Temperature
The Low Temperature Error (E11) occurs when the
temperature of the gas refrigerant at the barrel
sensor falls below -20°F. Although the machine
will not shut down, the active freezing cycle will
immediately end. This error usually occurs when
the machine continues to run in a low mix condition
or if the machine runs out of mix. The product
towards the front of the barrel tends to freeze solid.
Error Code 12 - Left Hopper Sensor
The Left Hopper Sensor Error (E12) indicates a
failure of the hopper sensor or an extreme out of
range condition (< -34°F or > 99°F). If the control
panel displays an E12, turn the left Freezing
Cylinder Off-On switch Off and back On. If the
control panel still displays the error condition
code, refer to the machine's wiring diagram and the
Temperature Sensor Chart (Figure 7-1). Check
each lead of the sensor to ground for continuity. If
continuity is found, replace the sensor. To check
