PRODUCT OPERATION
THEORY OF OPERATION
Principles Of Induction Heating
The use of induction heating in glass-ceramic
cooking devices has existed since 1987.
A temperature sensor under the glass is used
in order to protect the inductor, and it moreover
allows detecting that an empty container is
being over-heated and stopping the heating
process.
With this technique, the container is heated
directly. Therefore the cooking surface heats
up only as a result of the heat transmitted from
the container to the glass, which is much lower
than in conventional systems.
The base of the container is heated by the elec-
tric currents that circulate in its base and which
are induced by a variable, medium-frequency
magnetic field generated by the inductors lo-
cated underneath the ceramic glass.
Advantages Of Induction Heating
Faster Cycle Time
• Heatisdevelopeddirectlyandinstantlywithin
1 second inside the pot or pan, allowing a
much quicker startup than other heating
equipment. Heating process times can be
dramatically reduced & production output
can be significantly increased.
Only containers with a base made of ferromag-
netic steel or iron can be used with induction
cooktops.Containersthatcannotbeusedforin-
duction can be recognized by a magnet test.
Even though it is recommendable to use con-
tainers that fit the size of the cooking zone,
containers of a smaller diameter can be used
withoutcausingnotablereductionsofefficiency.
The cooktop control reduces the power deliv-
eredtosmallcontainersand,ifapplicable,stops
supplying power when the container does not
have the minimum required diameter.
• With induction cooking the heat level is every
bitasinstantaneous,andasexact,aswithgas,
yet with none of the many drawbacks of gas
(carbon monoxide, loss of flame etc.). Induc-
tion elements can be adjusted to increments
as fine as the cooking utensil cares to supply,
just like gas, and—again very important to
serious cooks—such elements can run at as
low a cooking-heat level as wanted for gentle
simmeringandsuchlike(somethingevengas
is not always good at).
The power inverter transforms the 50 Hz of
the power grid into an alternating current with
a frequency between 20 and 60 Hz.
Direct heating of the container base provides
the induction system with very fast heating.
Likewise, the system reacts very quickly to
power level changes.
High Thermal Efficiency And
Increased Profitability
Induction provides very precise control of the
powerlevels,whereforeitallowsdelicaterecipes
to be prepared.
• This energy-efficient process converts up to
90% of the energy expended into useful heat
to reduce utility costs. (With gas ranges up to
60% of the heat is normally wasted through
indirect gas combustion.) Stand-by losses
are reduced to a minimum.
• The costs of exhaust duct installation and air
conditioning running costs are saved.
3-1
• As mentioned earlier, induction cooking en-
ergyissupplieddirectlytothecookingutensil
by the magnetic field; thus, almost all of the
source energy gets transferred to that cook-
ing utensil. With gas or conventional electric
elements (including halogen), the energy is
first converted to heat and only then directed
to the pot or pan with a lot of that heat go-
ing to waste heating up your kitchen instead
of heating up your food. (As a comparison,
40%—less than half—of the energy in gas
gets used to cook, whereas with induction
84% percent of the energy in the electricity
used gets used to cook (and the rest is not
waste heat as it is with gas). There are two
important heat-related consequences of that
fact:
User-Friendly
• Working conditions are improved with the
absence of smoke and heat produced by
heating equipment. You can touch the outer
casing without getting burned.
• If the electricity supply to your home is inter-
rupted, you will be unable to cook; gas sup-
plies can be interrupted, too, but such inter-
ruptions are normally somewhat less likely
than electricity interruptions. If the electricity
where you are frequently goes out for hours
at a time, the loss of cooking ability may be
an issue for you.
Pinpoint Accuracy
• Powerinputispreciselycontrolledtoachieve
the exact temperature required for heating.
Heat is developed directly inside the pot or
kettle or cooktop.
Cooler kitchens:
• Of course the cooking vessel and the food
itself will radiate some of their heat into the
cooking area—but compared to gas or other
forms of electrically powered cooking, induc-
tion makes for a much cooler kitchen.
• With gas, when you adjust the element set-
ting, the energy flow adjusts instantly.
• But with induction cooking the heat level is
every bit as instantaneous, and as exact, as
withgas,yetwithnoneofthemanydrawbacks
ofgas.Inductionelementscanbeadjustedto
incrementsasfineasthecookermakercares
to supply, just like gas, and—again very im-
portanttoseriouscooks—suchelementscan
run at as low a cooking-heat level as wanted
forgentlesimmeringandsuchlike(something
even gas is not always good at).
Cool stove top:
• The stove top itself barely gets warm except
directlyunderthepan(andthatonlyfromsuch
heat as the pan bottom transfers). No more
burned fingers, no more baked-on spills, no
more danger with children around.
Environmentally Sound
• Induction heating is a clean, non-polluting
process. It produces much less smoke or
waste heat to alter the surrounding environ-
ment.
• Moreover, gas—induction’s only real com-
petition—has special risks of its own, not all
of which are as well known as they perhaps
should be. While the risk of a gas flame, even
a pilot light, blowing out and allowing gas to
escape into the house is relatively small, it
does exist.
• Itisanobviousbutstillveryimportantfactthat
inductioncooktopsarepoweredbyelectricity.
Not every home actually has a gas pipeline
availabletoit—formany,theonly“gas”option
is propane, with the huge propane tank and
regular truck visits. But everyone has clean,
silent, ever-present electricity.
Maximum Repeatability
• With modern induction heating equipment,
the heating pattern is always the same for a
given set-up, cycle after cycle and day after
day.
• Burning gas has byproducts that are vapor-
ized, but eventually condense on a surface
somewhere in the vicinity of the cooktop.

Noises that are Common to the
Normal Operation of Induction
Cooktops
Induction heating technology is based on the
capacity that certain metal materials have to
vibrate when they are subject to high frequency
waves.
NOTE: All these noises are normal and inher-
ent to induction technology, and they are not a
sign of any breakdown.
Under certain circumstances, these vibrations
may make certain sounds of a low volume due
to the following:
The noises that occur with greatest frequency
arethosewithcontainersthathavea“sandwich”
type base.
• Low tone noise, similar to that of a trans-
former: It occurs when cooking at high power
levels. It is due to the enormous amount of
energy that the cooktop is supplying to the
container. It disappears or attenuates as the
power level used is reduced.
Overview of Induction Cookware
• All pots and pans with a ferromagnetic base
are valid for induction.
• Only containers that have a base where a
magnet remains adhered can be used.
• Soft whistling: They occur when the con-
tainer is empty. They disappear or attenu-
ate when water or the food to be cooked is
added.
• The induction system does not heat up other
kinds of containers, and the power level in-
dicator on the display will blink.
• The minimum diameter of the container must
likewise be taken into account.
• Crackling: This kind of noise may occur in
containers composed of layers of different
materials. The noise is due to the vibration
in the separation zones between the various
layers of material. This noise is proper to the
container. It can change according to the
quantity and type of food that is cooked.
Pots and Pans good for Induction
Cooking
• Enamelled steel pots and pans.
• Cast iron pots and pans.
• Special stainless steel utensils for induction
cooking.
• Sharp whistling (beeps): They occur basi-
cally with containers composed of different
layers of materials when two adjacent cook-
ing zones are started up at the same time
and at maximum power. They disappear or
attenuate when the power is reduced.
Pots and Pans not good for Induc-
tion Cooking
• Non-ferromagnetic or non-metallic materials.
• Aluminum pots and pans.
• Copper pots and pans.
• Intermittentclicks:Theyarenoisescaused
by the commutations of the control electron-
ics, above all when low power levels are
selected.
• Brass pots and pans.
• Standard stainless pots and pans.
• Glass (“Pyrex”) containers.
• Earthenware pans.
• Fan noise: In order to control the correct
operationoftheelectronics,theymustworkat

cooktop is equipped with a fan that works at

or Service” in the Use & Care Guide.
Operational cooktop sounds
• Is there a low humming? This occurs when
cooking at high power. The cause of this is
the amount of energy which is transmitted
from the appliance to the cookware. This
sound will quiet or go away when the power
is turned down.
• Is the display flashing “F” and numbers?
If “F” and a number are alternately flashing
on the display, refer to the following table for
possible solutions.
• Is there a crackling? This sound occurs
when cookware is used which consists of
different materials. The noise is caused by
vibrations in the joint faces between the dif-
ferentlayers.Itmaychangedependingonthe

COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• Check all connections before replacing
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
• The most common cause for control failure
is corrosion on connectors. Therefore, dis-
connecting and reconnecting wires will be
necessary throughout test procedures.
• Resistance checks must be made with
power cord unplugged from outlet, and
with wiring harness or connectors discon-
nected.
• All tests/checks should be made with a
VOM or DVM having a sensitivity of 20,000
ohms-per-volt DC, or greater.
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
Refer to page 4-4 for the procedure for access-
ing the induction elements.
INDUCTION ELEMENTS
1. Unplug cooktop or disconnect power.
2. Disconnect the induction element wires
from the electronic board.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the in-
duction element wire terminals. The meter
should indicate less than 1 Ω.

Refer to page 4-6 for the procedure for ac-
cessing the negative temperature coefficient
(NTC) sensor.
NOTE: Each of the inductors uses a negative
temperature coefficient (NTC) sensor for moni-
toring the operating temperature. The sensors
are interchangeable. Use conductive grease
when replacing a sensor to aid in thermal con-
duction.

TOUCH CONTROL BOARD ERROR CODES
Error
U400
Description
U400 appears static on the display and indicates an acoustic signal when the electronics have been
connected erroneously at 400 V. (This warning appears when the measured voltage on the power
grids reaches 280 volts, and cases have occurred in which this warning appears at 250 volts). The
electric company can divert the supplied voltage by ±7%. Disconnect the cooktop from the AC line.
The failure disappears when the incorrect voltage is corrected.
F8
E
F and 8 blink alternately on the display corresponding to the cooking zone if the maximum cooking
time has been exceeded. The times depend of the power level and go from 1 to 10 hours.
“E” blinks alternately with the power level or the residual heat indicator when the corresponding sen-
sor has been pressed for too long (> 5 seconds), thereby sounding the acoustic signal. When the
“on” sensor is pressed for more than this time, “E” appears on all displays. It can occur due to liquids
spilled over the sensor zone, or due to an object that has been left on top. The indicator disappears
when the problem has been removed from the sensor and any other key is pressed.
F2
F4
F and 2 blink alternately on the corresponding display if the NTC temperature of the touch control is
excessively high (>100°C). If F2 appears, cooking zones 1 and 4 will not work.
F and 4 blink alternately on the corresponding display if the NTC temperature of the touch control is
excessively high (>100°C). If F4 appears, none of the 4 cooking zones will work.
ErXY

The touch control has an internal failure (except with Er32).
This warning occurs when a touch control of a 2l cooktop is connected to a 4l cooktop, or vice versa.
Check the replacement part.
