General information about water

Water- / Steam ratio

The conductivity of the connected water should be above 50µS/cm (micro Siemens).
The measured total hardness (TH) is normally higher than the measured amount of Carbonate hard­ness - calcium or magnesium carbonat (CaCO
Should the total hardness be less than the Carbonate hardness, most likely a water treatment system is

connected.

, MgCO3).

3

Common terms:
Total hardness TH is the measure of carbonate (CH) and non-carbonate
hardness (NCH) in the water
Carbonate hardness CH is the measure of bicarbonate (HCO3-) and carbonate
(CO3--) ions in the water;
Temporary water hardness; Forms sediments when
boiled;
Non-carbonate hardness NCH Calcium and Magnesum ions in the water;

permanent water hardness which can not be removed by
boiling

Water hardness e 1°dH = 1,25°e = 1,78°f = 17,8 ppm/l = 0,178 mmol/l

Chlorine Cl Gaseous, (used in swimming pools), limit 0,2mg/l
Chloride Cl-- chemical bond of chloride e.g. NaCl, limit 80mg/l

Water Analysis

Which values are required?

- Total hardness TH

- Carbonate hardness CH

- Conductivity in micro Siemens/cm

- Ideal: Water analysis with chloride content value

Possible reasons for corrosion

- excessive usage

- ferritic accessories

- rusting water pipes

- cleaning procedure (Unit is not dry over night)

- water

Water Info

Because of continuous examinations of systems for water treatment we would like to offer you some
information on different systems.
The given statements are only related to Rational units.

1. Recommended systems for water treatment

A) With pure scale problems in the steam generator we recommend hydrogen-(H+)-Ionic ex-

changer. This type of lter will extend the intervals between descales by approx. 5 to 8-times
of the normal descaling intervals. Please note that even with this type of lter it is still neces-

sary to descale the steam generator.

B) With a high chloride content above 80mg/l of water it is possible, that the interior cabinet will

start to corrode. To remedy this problem it is necessary to install a reverse osmosis lter.

C) With chlorine-contents above 0,2 mg/l of water an active carbon lter should be installed, to

avoid corrosive radicals when chlorine is heated up.

D) If the water is soiled with sand, iron particles or suspended matter a particle lter with

5-15 μm is recommended.

2. Limited recommended systems for water treatment

Physical systems for water treatment:

On some sites this type of water treatment showed satisfactory results. On other sites there was

no positive effect visible. Because of these circumstances we can not make a nal assessment of

this system.

3. Non recommended systems for water treatment

A) Sodium-Ionic exchanger:

With this lter system calcium is replaced by sodium. On chloride contents of the water above
50mg/l, sodium reacts with chloride to NaCl (=salt). This increase of salt in the water results in

a delay in boiling of the water. This delay in boiling can cause ”spitting” steam generators.

B) Silicate-dosing systems:

This kind of systems is problematic, as the adding of non conductive silicates, will inuence

the water level measurement.

Ultravent

Ultravent / Ultravent Plus

The Ultravent has to be connected to a separate power supply.
The Ultravent will be started by the BUS signal. (Combi Duo: The Ultravent is connected to the BUS
system of both units.)
The PCB Service part is always equipped with 2 Minit BUS connections and 2 RJ45 BUS connec-

tions.

In case the power supply to the Ultravent or the BUS connection is faulty, Service 35 (SCC_WE) or
E35 (CM_P) will be indicated.
If the Ultravent is nally disconnected, it must be deactivated in “Basic Settings”.

Ultravent

As soon as the BUS sends the signal „unit is running“ the Ultravent is running on low speed. When

the cabinet door is opened, it will switch to high speed. 1 minute after ending of cooking program the

Ultravent will switch off.
A Ultravent for Combi Duo and Ultravent Plus has 2 fan motors (ref. to circuit diagram below)

Ultravent und SCC / CM Index E-G

The BUS controlled UV is only supported starting with software version 01-07-11 (SCC)
and C1.07.01 (CM) accordingly

Ultravent Plus

The UV Plus is equipped with 2 lters. The state of the lter is monitored by differential pressure
switches and positioning switches and indicated by 1 LED each.

Filter 1 (pre lter) is located directly behing the front grease lters. In order to extend the life of the
main lter (2) and should be changed when the middle LED (LED1) is activ.

Filter 2 (main lter) is located on top of the Ultravent. This lter should be changed when the right LED
(LED2) is activ.

Should any of the positioning switches remain open (lter not inserted) the left LED „ERROR“ will show

red.

the lower unit (electric or gas) and one of the following base options:

1. Movable (front - back) on 40mm rollers

2. On castors (2 xed - 2 swivel)

3. On 150mm legs

The combination 101 on top of 61 shall not be assem­bled. Reason is the unfavourable center of gravity.

Only the combination 61 on 61, 61 on 101 and 62 on 102 in the base
option “movable” have the top GN runner not higher than 1600mm

under the condition the lower unit is an electric version unit.

Installation instruction you can nd on the Service DVD 7007.3080 or
on the Service Web site.

Thermo cabinet

The Thermo cabinet is available for unit sizes 61/101 and 62/102.

The heating elements are located inside the middle dividing wall.

This appliance must only be used in catering
establishments to keep plates and GN containers
warm!

Due to hygienic regulations the storing of food is
not allowed!

Condensation breaker steam

In order to guide the steam from the vent pipe of the quenching box
into a ventilation hood without affecting the humidity control we have
created 3 new condensation breaker as an accessory.

SCC_WE and CM_P 61, 62 and 101: 60.72.591
SCC_WE and CM_P 102: 60.72.592
SCC_WE and CM_P 201 and 202: 60.72.593

All pipes of the condensation breaker are made of stainless steel
for use also on gas units.

These condensation breaker can no be used on older units

of the SCC line

Draft Diverter Gas units

When discharging the ue gases of a gas unit into a chimney, a draft diverter type B13 must be used.

This draft diverter is equipped with a safety thermostat, which will interrupt the power supply to the
ignition box and stop the operation of the unit when the temperature in the draft diverter is above the
maximum allowable temperature.

8 different draft diverter and draft diverter with silencer are available:

Draft diverter Gas units 61 type B13 70.00.737

Sicotronic

Sicotronic stands for energy management systems and energy optimization plants for electro-thermal

and general electrical devices in a large-scale catering establishment.

Industrial customers pay electricity rate according to a maximum of Power consumption. Should the
amp draw exceed a set maximum the power supply company will charge a higher premium per KWh.
In order to avoid this current peak a surveillance system like Sicotronic is connected to the Power

meter which will disconnect individual consumers for a certain time according to a preset priority list.

For this purpose these consumers are connected to this system with a signal “energy demand ON”.

The feed back signal will be interrupted if needed.

The Sicotronic option must be ordered separately.

When retrotting Sicotronic, a new service part PCB is needed for SCC_WE and CM_P.

Ethernet Connection

SCC_WE:
Ethernet connectivity is a standard feature of all SCC_WE units. The PCB is equipped with an ethernet

interface which is supported with the standard software.

When ordering an unit with option Ethernet, the interface will be wired from the PCB to a position close

top the main power terminals.

SCC_WE oor units 201 and 202
To connect the Ethernet Interface to the PCB without having ordered the option “Ethernet” ex works a

special network cable with an angled plug must be used.

CM_P:
When ordering an CM_P unit with option Ethernet, a second PCB will mounted on top of the main PCB.

SC (Self Clean) Automatic CM_P

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.* and

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

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

4. the unit is switched ON.

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

In this case the „forced SC Automatic“ applies as follows:

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

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

* The marked values can be changed in unit specic ranges using the diagnostic program.

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

Manual Operating modes CM_P - Boiling point recognition

Steam mode in relation to boiling point recognition

During self test (after initial installation) the unit will determine the installation altitude by water boiling

point recognition.
As the boiling temperature declines with increasing altitude above sea level, the water boiling point
determines the installation altitude.

During self test the steam production will be active until the quenching sensor B2 reaches 70°C
(158°F). At this time the pcb will memorise the temperature measured by the interior cabinet sensor B1

as the boiling point temperature at the actual point of installation.

To run a manual cooking mode the following steps must be valid:

1. Cooking mode is selected.

2. Time or core temperature is selected.

3. Cabinet door is closed (door contact).

4. Fan motor is running (speed signal via bus).

5. In wet modes (Steam, Combination, Finishing) the steam generator must be lled with water (level
electrode)

6. In wet modes (Steam, Combination, Finishing) the steam generator will be preheated
(thermocouple steam generator)

ClimaPlus: Humidity control CM_P

In order to measure the humidity inside the interior cabinet the following pysical principle is used:

When the fan wheel is turning, the rear ns create a differential pressure on pressure sensor p1 via the
connecting hoses (inner and outer connection).

The pressure sensor P1 is supplied with 12V DC. When the fan wheel is at a stand still, the offset volt­age is between 0,45 - 0,55V DC.

The differential pressure is dependent on:

1. The speed of the fan wheel

2. The temperature in the cabinet

3. The amount of humidity in the cabinet

The following rules apply:
The output voltage of P1 is higher when the fan wheel turns faster.
The output voltage of P1 is higher when the cabinet temperature is lower.
The output voltage of P1 is higher when the humidity in the cabinet is lower.

This differential pressure is converted into a dc voltage for processing by the pcb.

Sample: CM_P 101E
NOTE: The given values are only average values and shall only demonstrate the relationship of pres-

sure values P1 to change in speed, temperature and humidity.

If the measured humidity value is too high, the clima valve Y5 will be activated and the closing disk will
be lifted. The negative pressure behind the fan wheel will cause dry air from the kitchen be sucked into
the cabinet. The humid air will be displaced and pushed through the cabinet drain into the quenching

chamber.

This Clima valve also functions as the safety relief valve.

Cross section of the clima valve:

Emergency humidity control:

In case of the differential pressure sensor P1 being defective (no signal), the steam generator will be
activated by time control automatically to a humidity level of 60%.
At the same time error „E 36“ will be shown.

Should the signal of P1 be out of the standard range (invalid signal), humidity will be controlled by the

quenching sensor.

At the same time error „E 37“ will be shown.

Self test

Self test

Note: Gas units: In case the unit was NOT delivered with the correct gas type configuration, it must be
converted prior of starting the self test. Please refer to gas manual!

CM_P units will run an automatic Self Test routine after installation. To start this please press the „Prog/
Start“ key.

This Self test will start under the condition, that the temperature of
B1, B2 and B4 are below 40°C (104°F).
Additionally 1 at and closed GN container (max 20mm) shall be

inserted into the cabinet with the opening facing down at a height
center to the fan wheel.

(201 - 202: 2 fan wheels = 2x GN containers)

The self test comprises a component test, calibration and

determination of the boiling point

After the component test (S2, M4, Y1) the calibration will start

with the offset setting on P1 before the unit will determine the
pressure values for all fan speeds and directions in cold and dry
condiition.
During step 200 the boiling point will be determined and stored.

This is followed by P1 calculating the pressure values for all fan speeds and

directions in steam and later combination mode 170°C (338°F).

Should at a later point in time the unit be reinstalled at a altitude more than 300m different to the original
installation height, a new self test should be initialized in order to determine the new boiling point.
Such re-initialization can be be done in Basic settings, SE20

step.

e.g. error 10 will be indicated, when the condition for calibra­tions is not given.

Reason: B1, B2 or B4 is above 40°C (104°F)

16 steps for each fan motor, (32 steps with oor models), e.g.
100: running fan motor at constant speed „1“

101: store P1 value at this given speed

e.g. error 200 is indicated, when the steam heating will not

reach the necessary 70°C (158°F) to determine the boiling

point in the allocated time.

Reason: e.g. SSR (energy optimising) or gas burner is not

activated etc.

e.g. error 302 is indicated, if sensor P1 does not give any or
any valid value at this time.
Reason: P1 defective or hoses to P1 blocked by water.

These errors are indicated during the respective calibration

step is running.

After solving the problem the Self test must be started again.

Bus

LED

100 - 240V

On oor units with 2 motors the bottom
motor carries a jumper for bus recogni­tion. This jumper is part of the wiring

harness.

Only when the motor is

connected to mains sup-

ply the green LED will

show and the bus signal
can be processed.

3AC 400V - 480V 61 - 202

NOTE: Gas units 62, 102 and 202 for countries with voltage 3AC200-240V, USA / Japan etc:

Gas units 62, 102 and 202 must be connected to L1 - L2, because the fan motor

40.03.513

is running on

200 - 250V only.

When changing the fan motor, a new motor shaft gasket must always be used!

There are 4 different fan speeds. It is possible that the motor will reduce speed independently to avoid

energy transfer by the rotating fan wheel.

The fan motor rotates clockwise - anti clockwise with a

120 second interval.

On oor units the bottom motor (with jumper) has a

60 second time lead in changing direction to the upper motor.

The bus system is equipped with a 6-pol Mini-Fit plug system.
In the bus system the individual components have individual addresses. Each address only exists once

in a unit.

The duplicated components in a oor unit, Fan motor bottom and Ignition box bottom are
identied with a jumper on the component. This jumper is part of the control harness.

The main pcb sends the action command via the bus cable.

Additionally the pcb receives information from the individual components via the same bus ( e.g. rpm).

The connecting sequence for the components on the bus is not important and can be chosen freely.

Control of cooling fan

61 - 102

The supply air cooling fan for units 61 - 102 behind the control panel is

controlled by a converter 230V AC - 24V DC.

The air lter under the control panel can be replaced by simply unlocking

it from the base frame.

The cooling air is discharged through the bottom of the unit.

201 - 202

The supply air cooling fan 201-202 on the rear left back panel is controlled

by a transformer pri. 230V AC, sek. 12V DC.

The air lter can only be changed after dislodging the protection cover

and sliding it to the right side.

The cooling air is discharged through the top left side of the rear panel.

Both supply air cooling fans are equipped with a temperature sensor

(NTC). This sensor measures the temperature at the position of the clima
valve Y5. The speed of the cooling fan increases with increasing tempera-

ture.

This sensor can not be changed separately.

The DC (supply air) cooling fan always runs when either of the following conditions are given:
B4 Temperature is above 130°C (266°F) or the CPU temperature is above 60°C (140°F) or the
cabinet door is open for less than 5 minutes (and the unit is switched on).

Additional 230V cooling fans distribute the cooling air in the electrical cabinet and cool the SSRs.

If the pcb reaches a temperature of approx. 65°C (149°F), “CHnG” “FILt” (change lter) will be dis­played. (This temperature is depending on unit size and energy.)
If a temperature of 80°C (176°F) is reached, any running cooking mode or program will be terminated
and error “E29” is displayed.

Calibration humidity

Calibration

1) Switch unit ON

2) On operator PCB set DIP switch 2 to „ON“ position

3) Select calibration with timer dial:

manual calibration

4) Activate manual calibration by pressing core temperature key

5)

To de-activate function test set DIP switch 2 to „OFF“ position
Switch unit off and on again.

.

Duration for calibration is 45 min for unit size 61-102 and 60 min for unit size 201-202.

Calibration:

Different food items cook best at their specic humidity level and specic temperature.
Vegetables are steamed, but roast is cooked at a specic humidity and mostly above 100°C (212°F)

To be able to achieve this task the unit must have stored specic pressure values for cold and dry (40°C
/ 104°F), 100% steam and combination e.g. 170°C / 338°F.

This basic information is evaluated during „selftest“ after installation or during manual calibration and
stored on the PCB and EEPROM.

Manual calibration has to be done when any of the below listed service work has been carried out:

1. removing of fan wheel / motor

2. changing thermocouple B4

3. changing differential pressure sensor P1

4. installation of a UltraVent or extraction hood on top of the unit

5. installation as the lower unit of a Combi Duo after it has done a selftest as a single unit

V02 en, CM_P - 34 -

Calibration: Steps

Pre condition before calibration

temperature of cooking cabinet sensor B1 is below 40°C (102°F)

temperature of quenching sensor B2 is below 40°C (102°F)

temperature of humidity sensor B4 is below 40°C (102°F)

door contact closed

heating: OFF
fan motor: OFF

left side panel closed, interior cabinet clean, if possible dry;
to achieve best calibration values insert a closed 20mm GN container
with opening facing down onto the rail closest to the center of the fan wheel

(201-202: 2 motors - 2x GN container)

e.g. error 200 is indicated, when the steam heating will

not reach the necessary 70°C (158°F) to determine the

boiling point in the allocated time.

Reason: e.g. SSR (energy optimising) or gas burner is

not activated etc.

e.g. error 302 is indicated, if sensor P1 does not give
any or any valid value at this time.
Reason: P1 defective or hoses to P1 blocked by water.

These errors are indicated during the respective cali­bration step is running.

After solving the problem the Selftest must be started

again.
