1.3 MODES OF NORMAL OPERATION

Following are details of the operational modes of the
IntelliTec control.

NOTE:

The preset amounts, times, and temperatures 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

When the Main Freezer Power is placed in the ON position,
the machine will start in the “Sleep 1 Mode". The display will
read "Sleep 1 Mode". The control will eventually move into
the “Sleep 2” mode if the PUSH TO FREEZE button is not
pressed. When the PUSH TO FREEZE button is pressed
the control will move to the “Serve Mode”.

B. Serve Mode

When the PUSH TO FREEZE button is pressed or a spigot
handle is pulled, the “Serve Mode” begins. The drive motor
starts, and after a 3 second delay, the compressor starts.
The display reads “FREEZING” on the top line and a bar on
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
the freezing cylinder. When the control senses the product
is at 75% of consistency, the display will read "SERVE",
the amber LED will go out, and the green LED will flash. At
this time, product can be served from the machine. The
drive motor and compressor will continue to run until the
toroid reads a preset value (CutOut amps). When the toroid
reads the CutOut amps on the drive motor, the compressor
turns off and the green LED will remain lit. After a 3 second
delay, the drive motor turns off. The product in the freezing
cylinder is now at serving temperature and consistency and
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.
When the temperature increases to a preset amount (Cut
In T), a 3-second drive motor pre-stir analyzes product
consistency. The pre-stir check is also performed each
time the spigot handle is opened. This check prevents over-
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 (Stir On and Stir Off). The stir cycle prevents product
separation. If a freezing cycle is initiated, the timer is reset.

In addition to the "Serve Mode" freezing cycle, there is a
freezing cycle based on a preset time (DftOffTime). If this
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
count setting is attained. The cycle count is the number of
active freezing cycles and is based on a preset value
(Cycles). Once the cycle count has been reached without
user interruption, the control will move into the "Standby
Mode".

If the PUSH TO FREEZE button is pressed or a spigot
handle is pulled, the cycle count is reset and the control will
move to the beginning of the "Serve Mode". Refer to Figure
1-3 for a graphical representation of the "Serve Mode".

C. Standby Mode

If no product has been drawn from the spigot and the preset
number of active freezing cycles is met, the control moves
into the “Standby Mode”. In "Standby Mode", the freezing
cycle is based on preset timers (On Time and Off Time), and
prevents ice crystals from building up in the product.
Because the product remains partially frozen, it can quickly
return to servable consistency when the PUSH TO FREEZE
button is pressed.

During “Standby Mode”, the stir cycle runs. This cycle is
based on preset, timed intervals (Stir On and Stir Off) and
prevents product separation.
