20

Off Time (sec)

 

Increasing this value will increase the time between 
freezing cycles in “Standby Mode” and result in 
an increase of product temperature in the barrel.

Stb Time (sec)

 

This setting determines the total amount of time 
in “Standby Mode”.

Sl1DrvOn (sec)

 

Adjustments to this setting affect the amount of 
time the auger rotates in the stir cycle. This stir 
cycle only occurs in “Sleep 1 Mode”.

Sl1DrOff (sec)

 

Adjustments to this setting affect the time between 
stir cycles. The stir cycle only occurs in “Sleep 1 
Mode”.

Sl2CutIn (°F)

 

Changing this setting affects the temperature at 
which the freezing cycle starts in “Sleep 2 Mode”.

Sl2CtOut (°F)

 

Changing this setting affects the temperature at 
which the freezing cycle stops in “Sleep 2 Mode”.

DftOffTm (sec)

 

In “Serve Mode”, this value determines the 
maximum time without a freezing cycle. If this 
value is met, a freezing cycle will start. In the event 
of a freezing cylinder temperature sensor failure, 
this value affects the amount of time between 
freezing cycles during “Serve Mode”.

Refriger

 

This setting changes how the control handles 
the storage refrigeration cycle. The setting for 
the O411 is Cabinet.

CabCutIn (°F)

 

If the Refriger value is set to Cabinet, this 
setting determines the temperature at which 
the refrigeration cycle starts. If None, 1 Hopper, 
or 2 Hopper is selected for the Refriger setting, 
CabCutIn will not be shown on the IntelliTec menu.

CabCtOut (°F)

 

If the Refriger value is set to Cabinet, this 
setting determines the temperature at which 
the refrigeration cycle stops. If None, 1 Hopper, 
or 2 Hopper is selected for the Refriger setting, 
CabCtOut will not be shown on the IntelliTec 
menu.

Cab Off

 

If the Refriger value is set to Cabinet and the 
temperature sensor in the cabinet fails, this setting 
determines the time between refrigeration cycles. 
If None, 1 Hopper, or 2 Hopper is selected for the 
Refriger setting, Cab Off will not be shown on the 
IntelliTec menu.

Cab On

 

If the Refriger value is set to Cabinet and the 
temperature sensor in the cabinet fails, this setting 
determines the length of the refrigeration cycle. If 
None, 1 Hopper, or 2 Hopper is selected for the 
Refriger setting, Cab On will not be shown on the 
IntelliTec menu.

4.8 OVERRUN 

ADJUSTMENT

The product, when served, is a combination of air and 
mix. Overrun is a measure of the amount of air blended 
into the mix.

Overrun can be expressed in terms of the amount of 
weight loss for a given volume. For example, if a pint of 
liquid mix weighs 18 ounces and a pint of frozen product 
with air added weighs 12 ounces, the overrun is said to 
be 50 percent: 18 oz. - 12 oz. = 6 oz., (6/12) x 100 = 50%

The overrun can be checked by placing a one pint con-
tainer on an ice cream scale and zeroing out the scale. 
Then  fi ll a one pint container with frozen product. The 
container should be fi lled over the top and leveled with 
a straightedge. The product should not contain any air 
pockets. When weighed on an ice cream scale, one pint 
of product should weigh 12 to 13 ounces.

The mix pump has been preset at the factory to produce 
a product with approximately 40% overrun. Because of 
differences in mix formulation, temperatures and baro-
metric pressure, this fi gure may vary. It will be necessary 
for approximately 2 gallons of mix to be pumped through 
the machine before overrun changes in the product are 
noticeable.

Overrun is controlled by the length of the air compressor 
piston stroke within the piston cylinder. Lengthening the 
stroke within the cylinder will increase overrun. Conversely, 
shortening the stroke will decrease overrun. To perform 
an overrun adjustment, refer to the following procedure:

WARNING

Hazardous Voltage

The Main Freezer Power switch must be placed in 
the OFF position when disassembling for servicing. 
The machine must be disconnected from electrical 
supply before removing any access panel. Failure 
to disconnect power before servicing could result 
in death or serious injury.
