PRODUCT OPERATION
THEORY OF OPERATION
Principles Of Induction Heating
The use of induction heating in glass-ceramic
cooking devices has existed since 1987.
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 located underneath the ceramic glass.
Only containers with a base made of ferromag
netic steel or iron can be used with induction
cooktops. Containers that cannot be used for in
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
without causing notable reductions of efficiency.
The cooktop control reduces the power deliv
ered to small containers and, if applicable, stops
supplying power when the container does not
have the minimum required diameter.
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.
Induction provides very precise control of the
power levels, wherefore it allows delicate recipes
to be prepared.
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.

Advantages Of Induction Heating
Faster Cycle Time
Heat is developed directly and instantly within
•
-
-
-
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.
With induction cooking the heat level is every
•
bit as instantaneous, and as exact, as with gas,
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
simmering and suchlike (something even gas
is not always good at).
High Thermal Efficiency And
Increased Profitability
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.
-
3-1
The costs of exhaust duct installation and air
•
conditioning running costs are saved.
•
As mentioned earlier, induction cooking energy is supplied directly to the cooking utensil
by the magnetic field; thus, almost all of the
source energy gets transferred to that cooking 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:
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.
Cool stove top:
The stove top itself barely gets warm except
•
directly under the pan (and that only from such
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.
•
It is an obvious but still very important fact that
induction cooktops are powered by electricity.
Not every home actually has a gas pipeline
available to it—for many, the only “gas” option
is propane, with the huge propane tank and
regular truck visits. But everyone has clean,
silent, ever-present electricity.
•
Burning gas has byproducts that are vapor
ized, but eventually condense on a surface
somewhere in the vicinity of the cooktop.
Electrical cooking of any kind eliminates such
byproducts.
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
Power input is precisely controlled to achieve
•
the exact temperature required for heating.
Heat is developed directly inside the pot or
kettle or cooktop.
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
with gas, yet with none of the many drawbacks
of gas. Induction elements can be adjusted to
increments as fine as the cooker maker 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 simmering and suchlike (something
even gas is not always good at).
•
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.
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.

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.
Under certain circumstances, these vibrations
may make certain sounds of a low volume due
to the following:
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.
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.
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.
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.
Intermittent clicks: They are noises caused
•
by the commutations of the control electron
ics, above all when low power levels are
selected.
Fan noise: In order to control the correct
•
operation of the electronics, they must work at
a controlled temperature. To achieve this, the
cooktop is equipped with a fan that works at
different speeds according to the temperature
detected. The fan can also continue operating
when the cooktop is turned off after being
used if the detected temperature continues
to be high.
NOTE: All these noises are normal and inher
ent to induction technology, and they are not a
sign of any breakdown.
The noises that occur with greatest frequency
are those with containers that have a “sandwich”
type base.

•
If “F” and a number are alternately flashing
on the display, refer to the following table for
possible solutions.
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 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
ferent layers. It may change depending on the
amount and type of food being cooked.
-
Is there a fan noise? The electronics re
•
quire a controlled temperature in order to
function reliably. The cooktop is fitted with a
fan which runs at various speeds according
to the temperature detected. The fan may
also continue to run even after the cooktop
has been switched off, if the temperature it
detects is too high.

TOUCH CONTROL BOARD ERROR CODES
Error Description
U400 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 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 “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 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.
F4 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).
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.
Cl The line power supply voltage is too low.
