2 SAFETY

2.1Safety warnings

Electrical hazard!

Repairs should only be carried out by the manufacturer’s technical staff.

Inadequate repairs can harm the users.

The sheath and framework may be subjected to voltage in case of failure.

The appliance should be disconnected from the mains before dismounting. It contains parts inside that are subjected to high voltage.

Always use a current-breaker switch if it is necessary to conduct lowvoltage tests.

The earth connection should not exceed standardised values. This is of the utmost importance for people’s safety and normal working conditions of the appliance.

Once the appliance has been repaired, it should be subjected to tests

VDE 0701 or the specific regulations that are in force in the country concerned.

The replacement of the power cable can only be carried out by authorised technical staff, using the replacement cable.

Special warnings for induction hobs!

Induction hobs comply with the safety and electromagnetic compatibility regulations currently in force (EN50366). People with fitted pacemakers should abstain from using or repairing such an appliance. The operation of the appliance may interfere with the operation of the pacemaker.

People with hearing aids may experience discomfort.

2.2Repair warnings

Warning!

Never attempt to carry out repairs involving the indiscriminate exchange of component parts.

Proceed in a systematic way, with reference to the technical specifications supplied with the appliance.

The electronic plates should not be repaired, but replaced with original spare parts. Exceptions are indicated in separate documents.

Components sensitive to electrostatic shock:

Respect EGB reference

Sharp edges:

Use protective gloves!

2.3EGB

2.3.1Concept

EGB = “Elektrostatisch Gefährdete Bauelemente“ (Electrostatic-

Sensitive Devices)

(Component sensitive to electrostatic shock)

2.3.2Pictogram

Electronic devices with components that are sensitive to electrostatic shock (EGB in German) are marked with the pictogram shown here.

2.3.3General specifications

The use of cutting-edge electronic technology in current electrical appliances guarantees high levels of profitability, protection of the environment, easy handling, operability and safety. Such highperformance technology can only be handled by qualified technicians with specialised knowledge.

All electronic modules and constructive units incorporate elements with a potentially dangerous electrostatic voltage.

2.3.4Dangerous components

Amongst others, these constructive elements are threatened by electrostatic voltage:

!µProcessors

!ICs

!Transistors

!Tiristors

!Triacs

!Diodes

!etc.

2.3.5Causes and effect

The human body can generate electrostatic charges in certain environmental situations. This charge is favoured by dry air and the coating on insulated floors.

People can transfer an electrostatic voltage:

!of up to 35,000 volts when standing on a non-conductive carpet.

!of up to 12,000 volts when standing on a non-conductive PVC floor.

!of up to 1.800 volts when sitting in a padded chair.

The electrostatic voltage in the human body is transferred to electronic devices and components that are sensitive to electrostatic shock by touching them, sometimes resulting in damage depending on the circumstances.

-constructive unit rendered useless

-equipment rendered useless

Light attack!

-damaged

-weakened

-premature failure

2.3.6Indications for components sensitive to electrostatic shock

In all electronic modules and constructive units there are components that are sensitive to electrostatic shock.

In order to protect such components, the following steps should be taken:

1.Read the corresponding label for the modules and constructive units with care.

2.Before touching and measuring any components that are sensitive to electrostatic shock, apply an electrostatic protection system (wristband with earth block).

3.Avoid touching these components with electrostaticallysensitive plastics (plastic sheeting, etc.).

4.Constructive units, modules and plate should be picked up as far as possible without touching the printed circuit boards and connections.

5.Components that are sensitive to electrostatic shock should not be located close to monitors or televisions.

6.For transport purposes, only conductive materials or the original packing should be used.

r630005d - 16.10.2008 – Dieter Helmich

Page 6 of 122

2.3.7Electrostatic protection system

There are several different electrostatic protection systems.

These electrostatic protection systems act to prevent the electrostatic shock from affecting the human body or by shunting the existing electrostatic voltage to earth.

In the electrostatic protection system used at the after-sales customer service, the electrostatic voltage in the body is transferred by means of a wristband and earth block.

For safety reasons, this is not carried out directly but using a combination of elements

The connection with the earthwire conductor or protective conductor should be in perfect condition

Combination of elements with wristband

3 COMPONENTS AND FUNCTION

3.1Electronic Induction (ELIN)

There are two types of elin (electronic induction).

!One with its own power supply (“left or main elin”)

!Another one without its own power supply (“right or secondary elin”), which is powered by the main elin.

They are attached to the elin bracket with clips, plus a couple of screws.

They communicate with the TouchControl through the LIN connector.

The TouchControl sends power level orders for each burner and the elin returns the state of the burner (pan recognition, error detection, etc.)

Depending on the type of model there are:

Domino		1 main elin
2I	60 cm	1 main elin
4I	60cm	1 main elin / 1 secondary elin
4I	70 cm	1 main elin / 1 secondary elin
4I	80cm	1 main elin / 1 secondary elin
3I		1 main elin / 1 secondary elin
5I	90cm	2 main elin / 1 secondary elin

3.1.3ELIN functions

3.1.3.1Power supply

Elins with their own power supply power the various components of the induction hob (fan, touchControl, elin without its own power supply, etc...)

3.1.3.2Regulation

The elin regulates the power of the inductors by means of the IGBTs

(insulated-gate bipolar transistors) and coordinates the signals given by the user through the control panel with the various induction zones.

3.1.3.3Communication

!The elin returns the state of the burner.

For example, if the pan is not detected, the power selected starts flashing (See pan recognition)

!It indicates the warnings and errors sent by the elin (See errors and warnings)

!It communicates with the touchControl by means of the 4-cable

LIn connector.

3.6ELIN support

In IH4 (previous project) there was a plastic support without a metal frame.

In the new IH5 project there are two types of support:

!ELIN support 1

!ELIN support 2

!Along with a metal frame, which makes it possible to insert the turrets for the cooking sensor and two more relay modules.

3.6.1ELIN support 2 for 60-70 cm hobs

3.6.2 ELIN support 1 for dominos and combinations

3.7Glass frame

3.7.1Characteristics

The inner framework of the glass frame units consists of 4 frames stuck together.

This design improves the tension that might be created.

The hermetic seal has been replaced by foam, which is fitted by robot.

Old seal

New seal = foam

There are greater advantages to be obtained with foam as opposed to using the hermetic seal:

!Automatically constant thickness

!Site of application is controlled

!Average flatness is reduced by 0.2 mm.

3.7.2Types

We have different sizes and styles for glass frame units. Sizes:

30 cm; 40 cm; 60 cm; 70 cm; 80 cm and 90 cm.

r630005d - 16.10.2008 – Dieter Helmich

Page 25 of 122

Styles

The various styles differ with respect to outer trim, colour of the glass and / or type of mounting, apart from the way the model can be recognised.

Black vitroceramic glass

Metal look vitroceramic glass

White vitroceramic glass

3.7.3Markings on glass

In the models for Balay and Lynx there is a label at the top on the right with the complete model without KI printed on it.

The other models only have the supplier’s number, at the top on the left, enabling us to find out what model it is.

This number is not easy to see. See photo below.

r630005d - 16.10.2008 – Dieter Helmich	Seite 26 von
122

All replacement glass frames will be supplied like this. However, they will have a sticker to remind the people handling them, printed with the following warning:

3.7.4Replacing glass frame for basic units

Warning!

The basic units have trim all around the edge of the glass.

Until recently, the outer metallic trim was completely stuck to the glass with silicon.

Now, although they will be supplied together, they will not be stuck with silicon but with foam, which only keeps the trim in place.

Thus, special care should be taken when handling the replacement glass frame, since it might fall and cause injury should the glass fall on top of us.

3.8Fan

3.8.1Characteristics and assembly

The fan used operates on direct current (without dynamo brushes) and contains electronic components.

It is connected to the ELIN plate by means of a 3-wire connection with some of the ends soldered to the fan’s circuit board

+24V

GND = earth

TACHO = tachograph

It is attached by means of clips (dominos and 2I). In other models it is attached to a bracket, which is screwed into place.

1.1.2 Function

To cool the electronic components.

Warning!

Between the content of the housing and the entrance of the fan there should be a gap of at least 2 cm.

Do not keep small objects and papers in the box, since these could be absorbed by the fan and reduce the cooling effect, or damage the fan.

3.9NTC

3.9.1Types

There are two types of NTCs.

!NTCs for the inductors.

!NTCs for the electronic module (ELIN)

3.9.2Characteristics and assembly

3.9.2.1NTCs for the inductors

In both IH4-I (previous project) and IH5-I (current project) the NTCs measure the temperature directly on top of the glass.

The difference lies in the way the NTC is mounted in the inductor and the fact that they have polarity (i.e. 3 channels for the frying function NTC).

For mounting purposes, a silicon support bracket is used instead of

a metal spring. This reduces the time taken to assemble the Photo of NTC and cross section of new IH5-I project component.

The external NTC has a 3-wire connector and controls the frying sensor function.

They are both interchangeable and have a different code number

(internal 2-wire NTC connector and external 3-wire NTC connector) and can be supplied as spare parts.
