CM4-S Cooking Computer — Overview

The S in the CM4­S computer stands
for segment, a
feature which
allows a cooking
cycle to be broken
into a number of
parts, each with its
own cooking
temperature and
time.

The graphic at
right details an
example of this
process. Explicit,
step-by-step
instructions are
provided in
subsequent
chapters.

Programming Overview

An example of a 13-minute cook cycle with four cooking temperatures
is detailed in the graphic below.
The cooktime and points at which the temperature will change are
entered in four steps in this example. Cook times are arrived at by
subtracting the desired segment time from the remaining cook time and
entering that number. (See explanation in the graphic.)

♦ Step 1 sets the total cook time and the initial setpoint.
♦ Step 2 sets the duration of the first cooking segment, 2 minutes,

and the setpoint of the first temperature change.

♦ Step 3 sets the duration of the second cooking segment, 4 minutes,

and the setpoint of the second temperature change.

♦ Step 4 sets the duration of the third cooking segment, 3 minutes,

and the setpoint of the third temperature change.
The four remaining minutes in the cooktime elapse at the final
temperature. No entry is required to use the final minutes.

Enter 13:00, the combined time of all cook cycles, and 340°F,
initial setpoint.

The CM4-S has a
number of features
and it is not
essential to use all
of them in your
cooking operation.
Programming for
segmented
cooking and
staggered alarms,
which are not
essential to use
together, are
extensive
processes.

For that reason,
programming for
filtering prompts
and alarms are
presented in
separate chapters.

CM4-S Cooking Computer — Overview

The CM4-S can cook in segmented and non-segmented cook cycles
with or without automatic filter prompts. It is also programmable to exit
a cook cycle in one of three modes: return to setpoint, assume an idle
temperature below setpoint, or prompt filtering at a prescribed cook
cycle count for a specific product button

The CM4-S is also capable of monitoring cook cycles initiated by all
the product buttons and call for filtering when the cumulative amount
reaches a number set by the operator.

Programming for filtering and exit-mode options are not essential to
basic cooking programming. For that reason, filtering and exit mode
instructions are provided in separate sections of this manual.

The sequence in which programmable features are encountered after

heated oil. The computer shrinks or stretches the cook time based on
the degree of cooling and the sensitivity setting. A 0 setting results in
no reaction; 9 produces the greatest reaction.

Alarms are set to
remind operators
to shake fry
baskets or tend to

some other way at
points during the
cook cycle. The
instructions at right
detail setting three
alarms in a 13­minute cook cycle.
To enter a single
alarm, exit the
