Part II – Explanation of Controls

A) Electronic Touch Pad – 

(Refer to figure 4)

Figure 4

This machine is equipped with two independent

electronic touch control pads. Each electronic touch
pad operates one side of the freezer.

Indicator Lights – L1 through L4

These indicators illuminate to show the selected

machine function. When illuminated, the machine is
in that respective mode.

Indicator Light – L5

This light will illuminate when the mix tank is low

or out of mix. It is also possible to activate a low
mix level beeper in the programming mode.

Monitor – Position 570

This numerical monitor will display the cylinder

product consistency while the machine is freezing
product in the automatic mode. When not freezing
the product in the cylinder, it will display mix tank
temperature in 

ALL

 modes.

Stop / Reset – Position 571.1

When in this mode, the indicator light L1 will be lit

and the machine functions off. From this mode you
can access the programming mode or switch to
operating modes.

Push to Select – Position 571.2

By pressing this button you can select any of the

following machine modes:
- Automatic
- Stand-by
- Beater
The indicator light will illuminate corresponding to
the mode selected with the touch pad.

Automatic Mode

When placed in this mode the indicator light L2 will
illuminate and the machine will start the freezing
process in the cylinder. During this freezing process, a
number indicating the cylinder consistency will be
displayed (monitor #570, the lower the number, softer
the product). The machine will continue to freeze the
product in the cylinder (numbers will increase) until
the preset HOT number value is achieved. After
achieving the preset cylinder consistency number
(HOT) the machine will then start cooling the mix
tank and display mix tank temperature.

Stand-By Mode

When placed in this mode the indicator light L3 will
illuminate. This mode is used during prolonged idle
periods. The mix temperature in both cylinder and
mix storage tank is maintained below 40 degrees F by
the electronic temperature probes. Product should not
be served while in this mode as it will be too soft. The
Monitor (#570) will only display the temperature in
the mix tank

 

while in this mode.

NOTE: If the mix level in the tank is below ½ full,
a warmer than actual temperature will be displayed
on the Monitor #570. The actual mix temperature
will remain at a safe temperature below 40 degrees F.

Beater Mode

When placed in this mode the indicator light L4 will
illuminate. This mode is used during the start-up
(pump fed), cleaning and sanitizing of the machine.
While in this mode the 

ONLY

 the beater / auger drive

motor will operate. This mode has a built in safety
device which will automatically switch the machine to
the stop mode after 15 minutes of operation. This
safety prevents an operator from inadvertently leaving
the freezer in this mode for extended periods of time,
which could damage the freezer.

Mix Tank Low Level Indicator

When low on mix in the mix storage tank, the
indicator light L5 will illuminate. This will indicate
that more mix is needed to operate the freezer. Each
mix tank has a maximum capacity of 18 quarts each.

DO NOT

 attempt to operate the freezer while low on

mix or your freezer may be damaged. It is also
possible to activate a beeper to sound when mix is
low in the Automatic and Stand-By modes. This is
done through the programming mode.
