Sensor Control Interface Circuit Boards - Electrolux Hob Service Manual

4.4.2 SENSOR CONTROL INTERFACE CIRCUIT BOARDS

This hob is provided with a touch sensor control
device.
To insert the controls in the hob, some sensors
interface electronic PCBs are used in place of the
normal buttons which control the switches placed in
the control unit.
The system consists of sensor PCBs placed under
the glass which recognise the presence of a finger
at a distance of about 4 mm from the sensors (glass
thickness).
The sensor PCBs include different control units with
touch sensors used on the basis of the control
software (see Fig. 9, 10 and 11).
The functions of the various controls and of the LEDs and displays are listed below.
