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.

1.3 MODES OF NORMAL OPERATION
Following are details of the operational modes of the
IntelliTeccontrol. NOTE:
Thepresetamounts, times, andtemperatures listed
below are references to actual settings on the
IntelliTec control. Refer to Table 1-1 on page 7 for
details on each setting.
A. Initial status
WhentheMainFreezerPowerisplacedintheONposition,
themachinewillstartinthe“Sleep1Mode".Thedisplaywill
read"Sleep1Mode".Thecontrolwilleventuallymoveinto
the“Sleep2”modeifthePUSHTOFREEZEbuttonisnot
pressed.Whenthe PUSH TOFREEZE button ispressed
thecontrolwillmovetothe“ServeMode”.
B. Serve Mode
WhenthePUSHTOFREEZEbuttonispressedoraspigot
handleispulled,the“ServeMode”begins.Thedrivemotor
starts,and aftera 3second delay,the compressorstarts.
Thedisplayreads“FREEZING”onthetoplineandabaron
the bottom line increases with product consistency. A
toroid on the IntelliTec control senses increasing drive
motor amperage as the product comes to consistency in
thefreezingcylinder.Whenthecontrolsensestheproduct
is at 75% of consistency, the display will read "SERVE",
theamberLEDwillgoout,andthegreenLEDwillflash.At
this time, product can be served from the machine. The
drive motor and compressor will continue to run until the
toroidreadsapresetvalue(CutOutamps).Whenthetoroid
readstheCutOutampsonthedrivemotor,thecompressor
turnsoffandthegreenLEDwillremainlit.Aftera3second
delay,thedrivemotorturnsoff.Theproductinthefreezing
cylinderisnowatservingtemperatureandconsistencyand
the green LED will remain lit.
After product is at consistency, the IntelliTec control
continuously monitors refrigerant temperature through a
thermistor mounted on the side of the freezing cylinder.
Whenthetemperatureincreases toapresetamount(Cut
In T), a 3-second drive motor pre-stir analyzes product
consistency. The pre-stir check is also performed each
timethespigothandleisopened.Thischeckpreventsover-
freezing of product, especially during frequent, small vol-
ume draws. If the product requires a freezing cycle, the
control will start the cycle.
During the “Serve Mode”, a stir cycle starts. This cycle is
independent of the freezing cycle and is based on preset
times(StirOnandStirOff).Thestircyclepreventsproduct
separation.Ifafreezingcycleisinitiated,thetimerisreset.
In addition to the "Serve Mode" freezing cycle, there is a
freezingcyclebased on apresettime (DftOffTime). Ifthis
time is attained without a freezing cycle, the control will
automatically start a freezing cycle. If a freezing cycle is
initiated, the timer is reset
The machine will remain in “Serve Mode” until the cycle
countsettingisattained.Thecyclecountisthenumberof
active freezing cycles and is based on a preset value
(Cycles).Oncethecyclecounthasbeenreachedwithout
user interruption, the control will move into the "Standby
Mode".
If the PUSH TO FREEZE button is pressed or a spigot
handleispulled,thecyclecountisresetandthecontrolwill
movetothebeginningofthe"ServeMode".RefertoFigure
1-3foragraphicalrepresentationofthe"ServeMode".
C. Standby Mode

intothe“StandbyMode”.In"StandbyMode",thefreezing
cycleisbasedonpresettimers(OnTimeandOffTime),and
prevents ice crystals from building up in the product.
Becausetheproductremainspartiallyfrozen,itcanquickly
returntoservableconsistencywhenthePUSHTOFREEZE
button is pressed.
During “Standby Mode”, the stir cycle runs. This cycle is
basedonpreset,timedintervals(StirOnandStirOff)and
preventsproductseparation.

The"StandbyMode"maintainsproductqualityduringslow
times,whileminimizingreactivationtime.Thismodelasts
for a preset time (Stb Time). Once this time has been
reached without user interruption, the control moves into
the "Sleep 1 Mode". Refer to Figure 1-4 for a graphical
representationofthe"StandbyMode".
If a spigot is opened or the PUSH TO FREEZE button is
pressed,thecontrolwillmoveto“ServeMode”.Productin
the front of the freezing cylinders may or may not be at
consistency. The state of the product is dependant on a
number of variables but will come to consistency quickly.
D. Sleep 1 Mode
After the “Standby Mode” time has expired without user
interruption,thecontrolwillmoveintothe“Sleep1Mode”.
During the "Sleep 1 Mode", the stir cycle is handled by
presettimers(Sl1DrvOnandSl1DrOff),andallowsproduct
to melt to a liquid state by using agitation cycles without
anyflow of refrigerant.Although the producttemperature
never increases above 41°F, the product thaws rapidly
whichminimizesproductbreakdown.Thecontrolwillstay
in the “Sleep 1 Mode” until sensing a preset temperature
(Sl2CutIn). When this temperature has been reached
withoutuserinterruption,thecontrolwillmovetothe"Sleep
2Mode".RefertoFigure1-5foragraphicalrepresentation
of the "Sleep 1 Mode".
If a spigot is opened or the PUSH TO FREEZE button is
pressed,thecontrolwillmoveto“ServeMode”.Ifthespigot
is opened in "Sleep 1 Mode", the product will not be at
consistency. The operator must wait until the first "Serve
Mode"freezing cyclehas completedto serveproduct.
E. Sleep 2 Mode
The “Sleep 2 Mode” maintains the freezing cylinder tem-
peraturebetweentwopresetvalues(Sl2CutInandSl2CtOut).
During the “Sleep 2 Mode”, the stir cycle runs. This cycle
isbasedonpreset,timedintervals(StirOnandStirOff)and
preventsproductseparation.The"Sleep2Mode"isoften
referred to by customers as the “night mode” and the
machine will stay in this mode until a spigot is opened or
the PUSH TO FREEZE button is pressed. When this
occurs,thecontrolwillmoveto“ServeMode”.Ifthespigot
is opened at this time, the product will be liquid. The
operator must wait until the first "Serve Mode" freezing
cyclehascompletedtoserveproduct.RefertoFigure1-6
foragraphicalrepresentationof the "Sleep2Mode".
F. IntelliTec Restart
If a hard error occurs (refer the hard error list below), the
IntelliTec control will wait 5 minutes then attempt to clear
the error by restarting itself. The control will count each
restartattempt.TherestartcountwillresetifthePUSHTO
FREEZE button is pressed, the spigot is pulled, or the
Freezing Cylinder OFF/ON switch is placed in the OFF
position.
Thefollowingareconsideredharderrors:

2 HighTorque
3 RunTime
4 Clean
7 DriveMotor
9 HighPressureCutout
When a restart occurs, the second line of the display will
read "Restart" and the backlight will blink. This will occur
regardless of the system mode.
G. Sleep 3 Mode
If a high torque, run time, or drive motor error condition
occursonthethirdrestartattempt,thecontrolwillmoveto
the "Sleep 3 Mode".
In"Sleep3Mode"freezingcylinderrefrigerationwillrunfor
4 seconds every 10 minutes. This ensures the product
temperature never increases above 40°F. The stir cycle
andthe auger do not run during "Sleep 3 Mode".
The control will exit "Sleep 3 Mode" if the PUSH TO
FREEZE button is pressed, the spigot is pulled, or the
Freezing Cylinder OFF/ON switch is placed in the OFF
position.
