Functioning
3.1
Adjusting the performance rate
The performance rate is adjusted by the potentiometer (control knob). The inductive
performance depends on the position of the potentiometer:
•
Position 1 = minimum power
•
Position 9 (resp. Position 12) = maximum power.
3.2
Check of the temperature
Induction coil
The temperature of the induction coil is checked by a temperature sensor. If the coil is heated
over the maximum temperature, the heating process is stopped. As soon as the coil has cooled
down, the Induction unit can be re-started. Turn the position of the kontrol knob on „0“ and
then on the required power level (see chapter 7.2 Error Messages).
Power board
The temperature of the heat sink is checked by a temperature sensor. As soon as the heat sink
is heated over 60ºC/140ºF, a cooling fan is started. A temperature of the heat sink of more
than 75ºC/167ºF will reduce automatically the power in order to keep the induction cooker
working under normal conditions. The internal temperature of the unit is supervised as well.
The power will be reduced when the temperature reaches 70°C/158°F. As soon as the
temperature reaches 80ºC/176°F the unit will stop working and show the error code E06 (see
chapter 7.2).
3.3
Overload current protection
When inappropriate pan material or magnetic objects are detected on the heating area, the
current in the induction coil may rise substantially. In order to protect the power board, the
coil current is checked. As soon as the current in the coil exceeds the tolerance, the generator
will cut out and there is no further active energy exchange. The unit can be re-started as soon
as normal working conditions are reached.
