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.

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 and depending on the display class, either the symbol for the time of day blinks or the arrow in front of the the ‘time of day’ symbol blinks.

b) With the +/- buttons, it can also be a separate component when necessary (input module) to set the time of day.

c) If need be, confirm with the MODE button (=Timer button) The appliance is ready for operation.

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, or, with appliances featuring a Temperature Selection

Switch, this must be put into the „Minus“ position when activating the MODE button (=Timer button).

Caution: the child-proof lock remains activated even when there is a voltage drop.

Additional important information on this subject is included in Chapter 3.6 "Special instructions on hob/oven communication in floor-mounted appliances".

DGS-TDS-N 05.09 A. B. © Electrolux - 8 599 521 367 EN

The oven door is locked at a centre of gravity temperature of the muffle of approx. 312°C, after a heating-up time of approx. 11 min.

The oven door is unlocked at a centre of gravity temperature of the muffle of approx. 204°C. The moment depends on the selected pyrolytic duration.

The cooling fan is running at an increased speed until the moment of unlocking. At a centre of gravity temperature of the muffle of approx. 130°C it switches off.

Attention écart pour les appareils stationnaires

3.3

High-speed heating - Explanation

Explanation:

Quick-Heating means reaching the selected oven temperature as quickly as possible.

After reaching the oven temperature, it switches back to the originally selected oven function (heating element configuration).

The Quick-Heating function is displayed depending on the appliance either by a symbol or by animated bar.

Note: Quick-Heating function - manual operation

Quick-Heating function „AUTO“ - Automatically active, not switchable

The type of Quick-Heating function available is in Chapter 3.1.

3.4

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:

Switch off appliance, or set selection switch to the 0 position

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) and Pyrolyse.

3.5

Safety function safety cutoff of cooking zones

If the cooking zones are not switched off after a certain period of time, or the temperature not changed, they switch off automatically.

The temporal cutoff depends on the set cooking level:

Functional parts - Oven control

4.1.1 Input electronic (UI) Avantgarde

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 program. The required oven functions are entered via a so-called touchboard.

-

5V supply voltage

Operating current 50mA for the electronic max. 110mA for LCD max. 150mA for touch incl. Lighting

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 (see figure) and drawing it afterwards to the right side of the appliance, the user interface can be removed backward, in direction of the appliance's interior.

With upright stoves, there may be different scenarios of fitting positions.

DGS-TDS-N 05.09 A. B. © Electrolux - 11 599 521 367 EN

Fig. Touch board stuck with switch panel Fig. Foil conductor

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.

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.

4.1.3 Temperatursensor 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.

Door locking systems

Door lock

The appliances with pyrolytic self-cleaning system are provided with a specific door lock system

(Fig. 1) This system prevents opening of the baking oven door with the pyrolysis switched on. The lock system is operated with 2 heated bimetallic elements which move a bar into position which then either blocks or releases the lock lever at the baking oven door. The system functions during the pyrolysis process independent of the electrical voltage.

The door lock is switched on at a temperature of the muffle centre of gravity (temperature in centre of baking oven) of 312 °C. Unlocking is at a temperature of approx. 180 °C via a Klixon (f11 in wiring diagram). The Klixon is arranged at the transverse beam beside the hot air motor (Fig. 2).

As soon as a voltage of 230 V is applied to the contacts 3 and 4, the bar “A” moves to the other side after 2 – 10 seconds and blocks the lock lever mechanically. The door cannot be opened. At the same time, the internal contact “B” opens and disconnects the lock path. The switch contacts 33/

34 close and signal that door lock is completed. The electronic signal completes the lock signal.

Internal contact “C” closes.

For unlocking, a voltage of 230 V must be applied to contacts 2 and 3. The bar “A” moves backwards and releases the lock lever. The door can be opened provided that the contact f11

(Klixon) is closed.

4.1.6 Light bar in the control panel

The illustrations show the light bar as a separate component and the electric terminals from the perspective of the interior of the device, on the left and on the right respectively. The installation occurs in the truss of the control panel. The control panel must be removed in order to be able to deinstall the light bar.

The activation of the light bar occurs through a activation electronics that is hafted on the lower surface of the front cover. It provides the light bar with a voltage of 7V/18mA.

100 % corresponds to a switching on period of 41 seconds

The hot plates are controlled via the bimetallic contact P 1-2. The input voltage of 230 V is applied here.

Depending on the position of the knob, this contact determines how often the hot plate is switched on or off during a certain unit of time by cycling the maximum heating power (230 V or 0 V between contact 2 and 4) (refer to performance characteristic).

Continuous operation at max. heating power is hot plate 9.

The power characteristic shows the power controller in cycling mode.

The average switching on period for each knob position can be read off in % of the cycled and/or max. power.

Any other switching step, approx. 18° results in a change of a resistance value which is transmitted by the conductor plate via data link to the HOC2000 user interface. So the input module works like a potentiometer.

Behind every rotation there is a specific resistance value, which on the other hand stands for a certain cooking level.

4.2.3 cooking zone power board HOC2000

This board consists of a number of relays, a transformer and other components which are necessary for the power supply of relays and input boards.

It receives the electrical control signals transmitted by the input boards and supplies the relevant heating element (cooking zones) with power depending on the impulse/s.

The control relays select the various cooking zones, its number may change according to the type of appliance.

Frequency:

230V

50Hz/60Hz

Max. working temperature: 85° C

The power board is marked with the variant number the production date (week/year)

The various plug tags (BRxx) and relays (Rxx) are specified on the board. These specifications can also be found on the wiring diagram.

Also on the power board there is a safety temperature limiter which stops the power supply and switches off the appliance when exceeding a board temperature of 130°C. After a successful cooling down it switches back again and the built-in cooktop can be put into operation.

Between contact BR19 (neutral) and BR22 (phase) it is possible to measure the mains voltage.

Deviations possible with floor-mounted stoves

5.2

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.

Oven rack protective circuit

Appliances with Pyroluxe self-cleaning system are provided with a microswitch. Dieser Mikroschalter befindet sich an der linken äußeren Seite der Komponentenplatte. Only with attached oven racks, not with slide-in grids, the microswitch interrupts a switch contact which prevents an activating of the pyrolytic function.

Measuring the temperature sensor

If a failure at the temperature sensor is assumed, the resistance can be checked by means of an ohmmeter.

The resistance of the temperature sensor should be 500 – 600 ohms at room temperature.

Make sure to measure the insulation resistance between the metallic housing and each connection terminal.

The resistance should be higher than 2 MOhms.
