1. ESD=electrostatic discharge
As the single electronic interfaces are not protected internally against statical electricity and are
partially open, you must pay attention to that, in case of a repair, there will be a potential
compensation via the housing of the appliance (touch it) in order to neutralize a possible charging
and to prevent a damaging of the affected electronic interface.
You also have to be careful with those electronics delivered as spare parts, which have to be put
out of the ESD protective package only after a potential compensation (discharge of possible
statical electricity).
If a potential compensation with an existing static electricity is not executed, it does not mean that
the electronic is demaged directly. Consequential damages may result due to the damaging of
internal structures which arise only in case of load through temperature and current.
Endangered are all assembly groups which are provided with control entries, wire paths lying open
and free-accessible processors.

2.3.2 Electronic child-safe function
Basic prerequisites: - Power supply voltage is connected
- No oven function selected.
- If the appliance is equipped with a Main Switch, then this must be
activated
To activate and deactivate the child-safety function, the MODE button (=Timer button) must be
activated together with the „„Minus“ button.
Caution: the child-proof lock remains activated even when there is a voltage drop.
2.3 Main features of operation
2.3.1 Clock setting following network reset
Information: The oven only functions with set time!
When the appliance must be connected again with the mains e.g. after a repair, you have to set the
clock anew. Proceed as follows:
a) Following connection or a power loss the symbol for the time of day blinks.
b) With the +/- buttons set the time of day.
c) If need be, confirm with the MODE button (=Timer button) The appliance is ready for
operation.

The user interface is positioned firmly in a plastic housing (E-box). The whole unit is locked in the
panel support. After pressing in the notch (Fig. 1) and drawing it afterwards to the right side of the
appliance (Fig. 2), the user interface can be removed backward, in direction of the appliance's
interior (Fig. 3).
At works the touch board is stuck directly onto the switch panel. Even in the need of replacement
the switch panel and the touch board form one unit. It is provided with nine sensors which transmit
the received impulses to the user interface. This happens via a data link in form of a foil conductor.
In addition to diverse semi-conductor modules, the Avantgarde input electronics mainly includes a
LCD display and a microprocessor. This controls the electronic control unit via a personalised pro-
gram. The required oven functions are entered via a so-called touchboard.

The power electronics are located on the rear side of the appliance and are accessible after
removing the housing rear panel. The power board is installed in a so-called „functions box“ made
of plastic. These two components, power electronics and plastic box, are also a replacement part
unit (see Ill.)
Please refer to Chapter 7 for connection designations and possible measuring points.

4.5 Temperature sensor PT500
The temperature in the baking oven is measured by a temperature sensor (type PT 500) for
appliances with control board. The sensor is provided at the rear of the appliance. It is used to
transmit to the electronic systems the values for:
- cyclic heating the radiators until the selected temperature is reached;
- switch off the radiators in case of overheating of defective sensor;
- switching ON/OFF the cooling fan.

4.6 The steam generator
Fig. 1 Fig. 2
The steam generator is siutated in the centre of the oven floor (fig. 1). To remove the steam
generator, the appliance must be laid onto the side panel. There is a cover on the housing floor
(service opening, fig. 2), which is screwed in position with six screws. These screws must be
loosened in order to access the steam generator and the two temperature sensors.
Fig. 3 Fig. 4 Fig. 5
The steam generator/temperature controller 120/170°C unit (figs. 3/4) is held with eight hexagon
nuts (fig. 5) which must be loosened before the component can be removed in the direction of the
applianceinterior.
Temperature controller 120°C - Signal tone lack of water (f3.2 in the circuit diagram)
Temperature controller 170°C - Deactivation steam generator (f3.1 in the circuit digram)
Heating element performance 1500W
Water capacity 0,7l

5. Technical equipment
5.1 Fan after-running
The cooling fan switches on automatically when putting the appliance into operation. First it is in
operation to keep cool the appliance surfaces. After the oven was switched off, the fan continues
running to cool the appliance and then switches off automatically at a centre of gravity temperature
of the muffle of approx. 120°C-130°C. The post-operative ventilation is controlled via the
electronics.
Note: - for wiring diagram see chapter 7
5.2 Measure against wrong electrical connection
Notprovided.
5.3 Safety function safety cutoff of oven
If the oven is not switched off after a specific period of time or if the temperature is not changed,
then it switches off automatically.
The oven switches off at an oven temperature of:
Putting into operation after a safety cutoff: Pressany button
Note: The safety cutoff is cancelled, when the clock function „duration“ or „end“ has been set.
Furthermore, it is not active with the functions, low-temperature cooking (bio cooking).

5.4 Temperature safety device
The double temperature fuse which deactivates all of the pols in case of overheating is situated
next to the OVC2000 powerboard. The measured temperature value upon deactivation amounts to
220°C (f2.1 and f2.2 in the circuit diagram).

6.2.1 Activating/deactivating Version a
Disconnect appliance approx. 10 sec from the supply mains. After the renewed connection „time of
day“ is lit, the display indicates „12.00“ . Now actuate the „selection“ key, afterwards activate the
demo mode by pressing together with the „selection“ and „minus“ key simultaneously within 2 sec.
For deactivating the demo mode please proceed in the same order.
The active demo Mode is confirmed by the time symbol in the display. When activating the Demo
Mode, please make a mental note of the positions of the „Selection“ and „Minus“ keys as these
have to be pressed once more in order to deactivate the Demo Mode but it is possible that these
arte not visible, depending on the date of manufacture and software version.
