COMPONENTS
Designation Function Features
Filter board
The filter board is used to eliminate the
voltage peaks originating from the mains
(hob protection and to protect the mains
from interference generated by inducers.
The filter board is composed of
• Several VDR
• High-value choke coils
• A power supply relay
• A fuse (fuse pad)
On IX2, IX4000 and IX6, the filter board
is integrated in the power board.
Keyboard board
The keyboard board is used to control
each of the sources. It is capable of
integrating a timer for the rear source.
Each generation of hobs uses different
keyboards. The communication with the
power board is multiplexed.
• IX1 : 2 14- and 4-wire connections
• IX2 : 2 14- and 6-wire connections
• IX3 : 6-wire connections
• IX3WR, IX4000, IX6: 8-wire
connection (same control logic).
Temperature sensor
The temperature sensor is an NTC
resistor.
Its function is to determine a possible
saucepan overheating, particularly in
event of heating when empty (no heat
dissipation)
In event of overheating, a power cut-off is
performed by the power board until
reaching the moderate temperature of the
source. This power cut-off is transparent
for the user (no modification to setpoint)
The temperature sensor is not used to
detect the presence of a container
The NTC is housed in a heat collector
(also called comb that is apparent or
integrated between a plate of mica (IX3,
IX3WR and IX4000) and an insulator.
• IX1, IX2, IX6 : 100 kΩ at 25°C
• IX3, IX3WR and IX4000 : 33kΩ at
20°C
