General hints:

Isolate the appliance from mains supply before opening the appliance

When working with chemicals, i.e. aggressive cleaning materials

always wear protective clothing, goggles and gloves!

After maintenance / repair the appliance must be checked for electric

safety in accordance with your national, state and local requirements!

Whenever working on any gas component like:

Gas valve, gas blower and / or changing connected type of gas a detailed

 ue gas analysis MUST be done using adequate CO and CO2

measuring equipment! This shall ONLY be done by trained technicians!

Always check appliance for possible gas leakages!

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. (CM - 45 min.)* 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

C

M

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. (CM - 90 min.) and

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

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

Steam Control CM

Intelligent steam control via quenching sensor

1. Filling of interior cabinet based on time and temperature control of B2 quenching sensor

2. After steam saturation inside cabinet steam will also  ll quenching chamber

70°C (158°F)

Notes:

B1 - 100°C(212°F)

B2 - 1

B2 - 2

t (sec)

3. Depending on the frequency of temperature raise of the quenching sensor B2 the duration of the next steam supply is calculated.

B2-1: B2 temperature with partial load B2-2: B2 temperature with full load

4. The amount of steam inside the cabinet is directly depending on the temperature

variation of quenching sensor B2.

Burner adjustment

Check the gas type adjustment at "Basic Settings".

How to carry

out a burner

adjustment:

1.

2.) Check the given length of the CO2 screw. See correct values from table above.

3.) Check gas input flow pressure. See correct values from table above.

4.) Select "Gas Steam Blower" at "Function Test". Exhaust temperature should be during the "gas flow analysis" above 200°C.

out first a CO2"Max" adjustment.

Carr

Setting of exhaust values only by CO

Carry out the CO

2

"Min" measurement. At CO2"Min" measurement no adjustment necessary on the CO2 screw => ! ! ! Check only the CO2 values ! ! ! !

2

screw adjustment. CO2 = see table above, CO = below 300ppm, if possible below 100ppm.

Repeat same measurements at "Gas Hot Air Blower Top" and "Gas Hot Air Blower Bottom (201-202)".

2

5.) Recommendation: Note down all actual values (mm, CO

, CO) inside the unit. This will help your fellow technician in fault finding!

Reason

1x Motor doesn’t start, no changing signal from hallsensor

2x Voltage too low on motor pcb

Remedy

Check for motor blockage or change motor.

Check supply voltage or change motor.

3x Voltage too high on motor pcb

4x rpm measurement defective

5x Motor pcb temperature >105°C

6x Supply voltage <80V

7x Motor pcb defective

8x Motor pcb defective

Humidity control SCC

The calculated humidity inside the cabinet is based on:

1. RPM signal of the fan motor (via BUS signal)

2. Temperature B4 (thermocouple behind motor mounting plate)

3. Voltage output signal P1 (depending on fan motor speed and humidity)

Die Offsetspannung P1 (Motor im Stillstand) liegt bei ca. 0.45 - 0.55V

The above mentioned I01 stands for STAT_xx.txt and S01 stands for SERV_xx.txt. These two files are numbered, as it is possible to download data‘s up to 4 times within 1 hour from the same unit. The files contain the service datas which are appropriate at the moment of the download. The file STAT.xx.txt shows the frequency of usage of the processes (SCC-process, customer program‘s, CleanJet and manual processes) (The file APLOG.txt is not relevant for service)

Gas conversion : SCC Gas

Whenever working on any gas component like:

Gas valve, gas blower and / or changing connected type of gas, a detailed  ue gas analysis

MUST be done using adequate CO and CO2 measuring equipment!

This shall ONLY be done by trained technicians!

Always check appliance for possible gas leakages!

S C C

Danger:

Changing the gas type of your SelfCooking Center or Combi Master shall

only be done if you have a ue gas analyser at hand.

Changing the gas setting only by adjusting the CO2 screw will result in an

unsafe ue gas condition and is dangerous to life

and will damage the equipment.

Select Basic Settings: A) • Switch on unit

• Open control panel

• Set DIP switch 1 on PCB to „ON“ position

• Select „Basic Settings B) At „Basic Settings“ select position „Gas type“

C) Press key and select with the central dial the new gas type G20=Natural Gas H, G25=Natural Gas L, G30=3BP, G31=3P, 13A=Natural Gas Japan

Burner adjustment

Check the gas type adjustment at "Basic Settings".

How to carry

out a burner adjustment:

1.

2.) Check the given length of the CO2 screw. See correct values from table above.

3.) Check gas input flow pressure. See correct values from table above.

4.) Select "Gas Steam Blower" at "Function Test". Exhaust temperature should be during the "gas flow analysis" above 200°C.

out first a CO2"Max" adjustment.

Carr Setting of exhaust values only by CO Carry out the CO

2

"Min" measurement. At CO2"Min" measurement no adjustment necessary on the CO2 screw => ! ! ! Check only the CO2 values ! ! ! !

2

screw adjustment. CO2 = see table above, CO = below 300ppm, if possible below 100ppm.

Repeat same measurements at "Gas Hot Air Blower Top" and "Gas Hot Air Blower Bottom (201-202)".

5.) Recommendation: Note down all actual values (mm, CO
