Edition 10-2008

RATIONAL SC Automatic

During the production of steam, the concentration of minerals inside the steam generator will increase
over time. These minerals settle on the heating elements and heat exchanger as well as the interior
steam generator walls.

In order to reduce this effect the steam generator will be pumped off and  ushed regularly depending
on the duration of steam production. This process needs approximately 45 seconds.
After emptying the steam generator it will be  lled automatically with fresh water.

There are 4 conditions to start this SC Automatic:

1. Heating time of the steam generator must exceed 60 min.* (SCC Care Control: 120min)
and

2. the temperature of the thermocouple inside steam generator (B5) must be below 65°C (149°F)
and

3. the temperature of the thermocouple inside interior cabinet (B1) must be below 70°C (158°F)
and

4. the unit is switched ON.

* - can be adjusted from 20-120min

In case the unit is used permanently the above mentioned temperature conditions
can not be met.

In this case the following 2 conditions apply:

1. The heating time of the steam generator reaches the twice the set duration*,
i.e. 120 min. and

2. the unit door is open for longer than 30 seconds

After completion of the SC-Automatic the accumulated steam heating time is re-set to zero.

SC-Automatic does not replace the need for descaling and/or installing water treatment lter

of the next steam supply is calculated.

B2 temperature with partial load

SCC

Edition 10-2008a

Intelligent cleaning process: The unit recognizes automatically the likely soiling of the
cabinet using the data of used cooking programs, cooking temperatures and running times.

Cleanjet demand

The customer usage (based on used cooking programs, cooking tem-
peratures and running times) determines the number of red bars in the
display “Cleanjet demand” ==> Intelligent cleanjet process.
If all bars show in red, “Care Control” is displayed.

CDS display

The number of pulses of the CDS sensor determines the number of red
bars in the CDS display.
If the customer always uses the recommended Care tabs when using
cleanjet, the steam generator will stay free of scale and the display will
not change to red bars.

Display Care Control

The combination of the above mentioned information is a measure of the
overall care status of the unit and as such the customers daily cleaning
pattern
Less cleaning (and less usage of care tabs) causes less blue bars.
Should the customer continue the low level cleaning pattern the bars will
start showing in red.

SCC

Edition 10-2008a

General information to software version SCC 04-01-01

Software SCC 04-01-01 can also be used for units with index „E“ (from 04-2004).

With this software you have the following options:

Using the button “Cleanjet request” you can select the “Intelligent Cleanjet request”.
In this case the cleanjet request will be based on used cooking programs, tempratures
and cooking duration.

Selecting Cleanjet you will see the below symbol in window 4 of your display:

The second setting to choose is Cleanjet request based on cooking time only (as known from older
software versions).
In order to deselect the Cleanjet request (turn symbol from red to blue again) select time functions
and setb time to “0”..

In Service Mode Basic Settings position 26 you select „Softwater“ ON to indicate only the half
amount of detergent tabs when cleanjet is choosen. The individual tab setting (as available since
software SCC 03-01-01) is no more existing.

Software SCC 04-01-01 in units with index „G“ (from 10-2008)

Basic Settings 26 „Softwater“

In Service Mode Basic Settings position 26 you select „Softwater“ ON to indicate only the half
amount of detergent tabs when cleanjet is choosen.

Basic Settings 28 „Selftest“:
After installation the unit will ask the user to start a Selftest. Water MUST be connected!

After the Clima Control valve and the drain valve have initialised the steam generator will  ll,
SC pump will start shortly and Y1 will re ll again.
In case the temperatures of B1, B2 and B4 are below 40°C now “Start” will be displayed.
After pressing “Start” the unit will adapt to the present installation conditions (duration appr. 15 min).
Should the unit be installed later at a different location, this “Selftest” can be re-initialised by setting
“Selftest” to ON in basic settings position 28.

Basic Settings 29 „Warranty“:

After  rst switch on the unit will prompt the customer to register and validate his second year war-
ranty online under www.rational-ag.com/warranty.
This prompting will discontinue after 4 days.
After registration a warranty certi cate will be issued:
In case the unit was installed in a show room or exhibition, this prompting can be re-initialised by set-
ting “Warranty” to ON in basic settings position 29.

Basic Settings 30 „Steam corrosion control“

The unit automatically recognises if the customer used it predominantely in steam mode. In case this
usage is more than 90% during the last 20 hours of operation the unit will prompt a Cleanjet request
daily regardless of the total duration of cooking time

Basic Settings 31 „Care Control Reset“

By setting the switch to “ON” all Care Control bars will be set to blue.

SCC

Edition 10-2008a

It is possible to abort the cleanjet program. However the abort program of 30min. can not be short-
ened again as the steam generator must be neutralised from possible remaining care solution.

Cleanjet Abort program

During the abort program the steam generator will first be filled with Y1. After draining the steam eg-
nerator it will be filled a second time to a level above the level electrode. After a second draining the
steam generator will fill again exactly to the level electorde.
In case the level electrode does not recognise the water Error 120 will be shown.
At the end of the abort program a short steam period and rinsing the cabinet with Cleanjet pump will
follow.

The duration of steam heating time unitl next SC automatic is now 120min (units with index “G”) .
However should the steam generator develop scale because the customer does not use the care
tabs, this time will automatically be reset to 60 minutes.

Clima Plus Control SCC

The calculated humidity inside the cabinet is based on:

1. Voltage output signal P1 (depending on fan motor speed, ref: function test #5)

2. Temperature B4 (thermocouple behind motor mounting plate)

3. RPM signal of the fan motor (via BUS signal)
The offset voltage of P1 (Motor not turning) is appr.: 0.45 - 0.55V

Basic rule: The less humid, the higher is the voltage of P1,

The higher the rpm, the higher the voltage of P1.

Basic Settings 28 „Selftest“:
After initial installation the unit will automatically run into a „Selftest“
mode. The operator is prompted to remove all containers and packing
material from the cabinet. After appr. 1 minute a „Start“ buttom will ap-
pear under the condition B1, B2 and B4 is below 40°C (104°F).
Note: For this mandatory start-up function water must be connected!

Basic Settings 29 „Warranty“:
After  rst switch on the unit will prompt the customer to register and
validate his second year warranty online under www.rational-ag.com/
warranty.
This prompting will discontinue after 4 days.
In case the unit was installed in a show room or exhibition, this
prompting can be re-initialised by setting “Warranty” to ON in basic
settings position 29.

Basic Settings 30 „Steam corrosion control“
The unit automatically recognises if the customer used it predominan-
tely in steam mode. In case this usage is more than 90% during the
last 20 hours of operation the unit will prompt a Cleanjet request daily
regardless of the total duration of cooking time

Basic Settings 31 „Care Control Reset“
By setting the switch to “ON” all Care Control bars will be set to blue.
