A Few Words About Safety
Safety Information
Read and understand the entire manual before
operating or maintaining Stoelting equipment.
This manual provides the operator with information
for the safe operation and maintenance of Stoelting
equipment. As with any machine, there are hazards
associated with their operation. For this reason safety
is emphasized throughout the manual. To highlight
specific safety information, the following safety defini-
tions are provided to assist the reader.
The purpose of safety symbols is to attract your at-
tention to possible dangers. The safety symbols, and
their explanations, deserve your careful attention
and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.
If you need to replace a part, use genuine Stoelting
parts with the correct part number or an equivalent
part. We strongly recommend that you do not use
replacement parts of inferior quality.
WARNING
The signal word “WARNING” indicates a potentially
hazardous situation, which, if not avoided, may result
in death or serious injury and equipment/property
damage.
CAUTION
The signal word “CAUTION” not preceded by the
safety alert symbol indicates a potentially hazardous
situation, which, if not avoided, may result in equip-
ment/property damage.
NOTE (or NOTICE)
The signal word “NOTICE” indicates information or
procedures that relate directly or indirectly to the
safety of personnel or equipment/property.

1.4 MODES OF NORMAL OPERATION
Following is an explanation of the normal operation modes
on the E122 and F122 (Refer to Figure 1-3).
NOTE
The machine uses the torque switch to maintain
product consistency. The IntelliTec2™ controls
the timers which include Pre Stir, Post Stir and Off
Time (standby).
A. PRE STIR
When the Push To Freeze button is pressed or when
the spigot is opened, the drive motor starts a 5-second
pre stir. The torque switch determines if a freezing cycle
begins. If the consistency of the product holds the torque
switch closed for 3 seconds the machine goes to Standby.
Otherwise a freezing cycle begins.
B. FREEZING CYCLE
The freezing cycle runs until the torque rod closes the
torque switch and keeps the switch closed for 3 seconds.
If product consistency is not met within 20 minutes, the
machine operates in the compressor time out mode (See
Section 1.5).
NOTE
If the spigot is pulled during a freezing cycle, the
20-minute timer restarts.
C. POST STIR
After the freezing cycle ends, the drive motor continues
to run for a 12 second post stir. The post stir ensures the
product does not freeze to the cylinder. If the spigot is
opened during the post stir, the machine checks consis-
tency. If the product is at consistency, the machine goes to
standby. If the product is not at consistency, the machine
starts a freezing cycle.
D. STANDBY
The machine remains in Standby for 5 minutes or until
the spigot is pulled. At the end of Standby the machine
goes to Pre Stir if the cycle count has not been met. If the
cycle count has been met it goes to Refrigerate Mode.
E. REFRIGERATE MODE
After the cycle count is met without a spigot pull, the
machine is in Refrigerate Mode. It remains in refrigerate
mode until the spigot is pulled.
F. CLEAN MODE
When the Clean button is pressed, the drive motor starts
and runs for 20 minutes. After the 20 minutes expire, the
drive motor stops and a Clean alert will be displayed on
the IntelliTec2™. To clear the alert, press the On/Off button
for the cylinder to turn it off then press it again to turn it on.

A. COMPRESSOR TIME OUT MODE
If the freezing cycle exceeds 20 minutes, the machine
operates on timers (Refer to Figure 1-4).

If the mix level falls below the sensor probe, the machine
operates on timers. The machine continues to operate
on timers until the mix level in the hopper is above the
sensor probe (Refer to Figure 1-5).

C. DRIVE MOTOR ERROR MODE
If the control does not sense current from the drive motor
during a pre stir, the machine goes into standby mode for
12 minutes. After standby, the control repeats the pre stir
and attempts to sense drive motor current. After the third
pre stir without sensing drive motor current, the machine
operates on timers. If the spigot is pulled during standby,
the machine immediately attempts to sense drive motor
current.
Continues to operate until the
cylinder is turned off then on again
using the On/Off button.

Selecting Left or Right Output Control goes to a screen
that allows motors, solenoids, or the compressor to be
individually activated.Activate by moving the cursor to the
desired component and pressing the SET button.
Selecting Left/Right Monitoring goes to screens that show
current statistics of the selected cylinder.
The Test Monitoring screens can be used for immediate
feedback when troubleshooting. For example the spigot
switch can be tested by opening the spigot and observing
if the status text changes from "Closed" to "Open".

used to enable the clean warning mode or the clean
lockout mode. When one of the modes is enabled and
the machine is not cleaned within a specified period, the
machine will either display a warning (for warning mode)
or remain in sleep mode and not go into serve mode (for
lockout mode).

The Testing and Manual Operation menu provides access
for individual components to be energized to assist with
troubleshooting. There are also test monitoring screens
