1. Installation instructions
1.1. Installation conditions
All the infrared sensors must be in contact with the glass surface.
No movement of the control under the glass ceramic after installation must be assured.
1.2. Printing on glass
The glass printing area over the sensors must be centred with the sensor.
Glass printing thickness in an area of 10mm around the center of the keys <= 0.5mm.
1.3. Type of glass
Glass thickness 4mm. Glass infrared light transmission wavelength range of 925nm.
1.4. User interface initial calibration
The User Interface has implemented an initial keyboard calibration focused to adapt the sensibility of the keys, to the
final mechanical, environmental and user conditions.
Any time the Cooktop is plugged or there is a power failure that generates a reset in the user interface, the first time the
Key Lock is touched the sensitivity of the keyboard is readjusted. This first touch of the Key Lock must be done in certain
conditions:
Do not use gloves
Use a clean finger.
Touch the glass (smooth touching).

Installation Instructions

1.5. Initial Light Conditions
When power is initially applied to the Cooktop, the touch control conducts a calibration process for the touch keys, which
requires a low level of ambient light in the area of the touch keys.
If during this calibration process excessive ambient lighting is detected the User Interface displays "FL" (Infrared
Ambient Light Error) and the control calibration process is suspended. In order to rectify the process any lighting that could
affect the calibration process should be switched off (e.g. halogen cooker hood lighting). The error will disappear when
satisfactory ambient lighting is detected and the touch control calibration procedure will now complete satisfactorily.
Notes:
1) The "FL" error can only be generated within approx 3s of initial power being applied to the cooktop.
2) We recommend that the user switches off all cooker hood lighting and lighting directed towards the cooktop when
power is initially applied to the cooktop.
3) After the touch control has conducted its initial calibration process, (approx 3s) any cooker hood or other lighting can
be switched on as normal and will not affect the operation of the touch control.

(2) Due to some kinds of overvoltage disturbances in the mains that can damage internal electronic, the ecook system
includes an overvoltage protection circuit to protect itself. The protection circuit disables the power circuit to cut the absorved
power of the induction. There are 2 protection circuits.
Depending on disturbance energy and voltage level, both protection circuits can be activated or only one related to the left
side heaters or one related to the right side heaters.
So the way to visualize this protection activation in the Touch control for a 4 heater is:
Protection
Left two displays
Right two displays
Left side activated
“U”
Right side activated
“U”
Both activated
“U”
“U”
This “U” message is the same as the Not Pan Detection situation.
Normally, in a normal cooking, the disturbance takes a few seconds. The ECOOK includes a filter to don’t show the “U” so
easily, this means, the protection actuates but “U” is not showed just with one short disturbance. The decision to show “U” is
taken after a defined nº of disturbance pulses.
