2 SAFETY
2.1 Safety 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.
2.2 Repair 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!

2.3 EGB
2.3.1 Concept
EGB = “Elektrostatisch Gefährdete Bauelemente“ (Electrostatic-
Sensitive Devices)
(Component sensitive to electrostatic shock)
2.3.2 Pictogram
Electronic devices with components that are sensitive to
electrostatic shock (EGB in German) are marked with the
pictogram shown here.
2.3.3 General 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.
2.3.4 Dangerous components
Amongst others, these constructive elements are threatened by
electrostatic voltage:
! µProcessors
! ICs
! Transistors
! Tiristors
! Triacs
! Diodes
! etc.
2.3.5 Causes 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.
r630005d - 16.10.2008–Dieter Helmich Page 6 of 122
Mortal attack!
- component rendered useless
- constructive unit rendered useless
- equipment rendered useless
Light attack!
- damaged
- weakened
- premature failure
2.3.6 Indications 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 7 of 122
2.3.7 Electrostatic 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
r630005d - 16.10.2008–Dieter Helmich Page 8 of 122
3 COMPONENTS AND FUNCTION
3.1 Electronic 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

3.1.3 ELIN functions
3.1.3.1 Power supply
Elins with their own power supply power the various components of
the induction hob (fan, touchControl, elin without its own power
supply, etc...)
3.1.3.2 Regulation
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.
3.1.3.3 Communication
! 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.

3.6 ELIN 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.
3.6.1 ELIN support 2 for 60-70 cm hobs
3.6.2 ELIN support 1 for dominos and combinations

3.7 Glass frame
3.7.1 Characteristics
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.
3.7.2 Types
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 Seite 26 von
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
3.7.3 Markings 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 27 von

3.7.4 Replacing 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.
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:

3.8 Fan
3.8.1 Characteristics 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.
r630005d - 16.10.2008–Dieter Helmich Page 29 of 122
3.9 NTC
3.9.1 Types
There are two types of NTCs.
! NTCs for the inductors.
! NTCs for the electronic module (ELIN)
3.9.2 Characteristics and assembly
3.9.2.1 NTCs 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
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.
