Cata ISB 704 BK - Manual (Page 19)

Insert in the fixed wiring a mean for
disconnection from the supply mains
having a contact separation in all poles
that provide full disconnection under
overvoltage category III conditions, in
accordance with the wiring rules. The plug
or omnipolar switch must be easily reached
on the installed equipment.
This appliance is not intended to be used
via an external timer or a remote control
system.
The manufacturers decline any responsi-
bility in the event of non-compliance with
what is described above and the accident
prevention norms not being respected and
followed.
To avoid all risk, if the power cable
becomes damaged, it must only be
replaced by the manufacturer, by an
authorised service centre, or by a
qualified electrician.
OPERATING PRINCIPLE (Fig. 1)
It exploits the electromagnetic properties of most cooking
vessels.
The coil (inductor) which produces the electromagnetic field is
operated and controlled by the electronic circuit.
The heat is transmitted to food by the cooking vessel itself.
The cooking process takes place as described below.
- loss of heat is minimum (high efficiency)
- the system stops automatically when the vessel is removed or
even just lifted from the hob
- the electronic circuit guarantees maximum flexibility and fine
adjustments.

Installation
All operations relative to installation (electric connection) should
be carried out by skilled personnel in conformity with the rules
in force.
As for the specific instructions see part pertaining to installer.
Switching the Touch Control ON/OFF “Z”
After mains voltage is applied the control initializes for approx.
1 second before it is ready for operation.
After a reset all displays and LEDs glow for approx. 1 second.
When this time is over all displays and LEDs extinguish and the
control is in the stand-by mode.
Press the ON/OFF (1) button to switch the touch control on.
The cooking zone displays show a static “0“.
If a cooking zone is in the “hot“ status, the display shows a static
“H“ instead of “0“. The bottom right dot is blinking in 1 second
intervals on all cooking zone displays to indicate that no cooking
zone is selected at the moment.
After switching-ON the electronic control remains activated for
20 seconds. If no cooking zone or timer selection follows within
this period of time, the electronic control automatically switches
back into the stand-by-mode. The control can only be switched-
ON if it identifies the ON/OFF key alone being operated. Should
it recognize key activation other than that, the control remains
in the standby- mode.
If the child safety feature is active when switching on, all
cooking zones show “L“, (LOCKED). If the cooking zones are
in a “hot“ status, the display shows “L“ and “H“ in alternation.
When the Touch Control is ON it can be switched- OFF at any
