Protection against unintended switching-ON
· If the electronic control realizes a continuous operation of keys
for approx. 10 seconds, it switches OFF automatically. The
control sends out an audible failure signal for 10 seconds, so
that the user can remove the object which has been mistakenly
placed onto the operation surface. The displays show the
failure code " E R 0 3 " . If the failure carries on for more than
10 seconds, only the code "E R 0 3 " will be displayed as long
as the failure will be recognized by the electronic control. If
the cooking zone is in the "hot" status, "H" will appear on the
display in alteration with the failure notice.
· If no cooking zone will be activated within 20 seconds after
switching-ON by means of the Power-key, the control switches
back from the ON-condition into the stand-by-mode.
· When the control is switched- ON the ON/OFF-key has priority
over all other keys, so that the control can be switched-OFF
anytime, even in case of multiple or continuous operation of
keys.
· In the stand-by mode a continous operation will not be
signalized. However, before the electronic control can be
switched-ON again, it has to recognize that all keys are not
operated.
Key lock (child safety feature)
◊ Child safety feature:
Key lock:
After switching-ON the control the child safety feature can be
activated. To achieve this it is necessary to simultaneously
operate the front right cooking zone- select-key and the
MINUS-key and then press the front right cooking-zone-select
key again. There will be an "L", meaning LOCKED (child safety
feature against unintended switching-ON). If a cooking zone is in
the "hot" condition, "L" and "H" will be displayed in alternation.
This course of operation has to take place within a period
of 10 seconds, no other key than described above may be
operated. Otherwise the input will be interrupted because of
incompleteness, the cook top will not be locked then.
The electronic control remains in a locked condition until it gets
unlocked, even if the control has been switched-OFF and -ON in
the meantime. Also a reset of the control (after a voltage drop)
does not cancel the key lock.
Unlocking for cooking purposes: :
To unlock and operate the control it is required to operate
the front right cooking- zone select- key and the MINUS-key
simultaneously. "L" (LOCKED) in the display extinguishes and all
cooking zones show "0" with a blinking dot. Should a cooking
zone be "hot", "H" is displayed instead of the static "0". After
switching- OFF the control, the child safety feature is active again.
Cancelling the key lock:
After switching-ON the control the child safety feature can be
deactivated. Here it is necessary to simultaneously operate the
front right cooking-zone-select key and the MINUS-key and then
operate the MINUS-key alone. If all steps have been carried out
in the right order within 10 seconds the key lock gets cancelled
and the control is OFF. Otherwise the input will be considered
incomplete, the control remains locked and switches-OFF after
20 seconds.
After a renewed switching-ON by means of the ON/OFF key all
displays show „0", the display dots are blinking and the control
is ready for cooking. If a cooking zone is in "hot" mode, "0" and
"H" will be alternately displayed.
Audible signal (buzzer)
While the control is in operation the following activities will be
signaled by means of a buzzer:
· normal key activation with a short sound signal.
· continuous operation of keys over a longer period of time
(_10 seconds ) with a longer, intermittent sound signal.
Timer function (optional)
The timer function is realized in two versions:
· Stand-alone timer 1..99 min: sound signal when the time is
over (= minute minder). This function is only available when
the cooktop is not in operation, i.e. when there is no cooking.
· Cooking zone timer 1..99 min: sound signal when the time is
over, four cooking zones can be programmed independently.
Timer as minute minder (stand-alone):
· If the control is ON and no cooking zone selected, the
standalone-timer can be used by simultaneously operating
MINUS (2) and PLUS (3) keys.
· Adjustment range (0-99min), it can be set in 1-minute steps
with any key, starting at 1 up to 99 (end stop) with the minus-
key starting at 99 down to 0 (end stop)
· Continuous activation of the plusor minus-key results in a
dynamic increase of the adjustment speed up to maximum
value without sound signal.
· when the plus- or minus key is released in the meantime, the
adjustment speed starts again from a (low) initial value.
· adjustment can be made with a continously activated plus- or
minus-key or by tip-operation (with sound signal) After the
timer is set the time runs down according to the adjustment.
When the time is over there is a sound signal and the timer
display blinks.
The sound signal will be stopped
· automatically after 2 minutes and/or
· by operating any key.
Then the blinking of the timer display stops and the display
extinguishes.
Switching-OFF/changing the timer
· The timer can be changed or switched-off anytime by
simultaneously operating MINUS (2) and PLUS (3) keys. (with
sound signal). The timer will be switched off by counting down
to "0" with the minus-key.
For 6 seconds the timer display remains at "0" before it will be
switched-off.
· If the control will be switched- ON by means of the Power-key,
the stand-alone timer will be switched-off also.
Timer programming on cooking zones
When the control is switched- ON an independent timer can be
programmed for every cooking zone.
· By selecting a cooking zone with the cooking-zone-selectkey (4),
then selecting the setting and, finally, operating MINUS (2) and
PLUS (3) keys simultaneously, the timer can be programmed
as a switch-off function for a cooking zone.
· During timer programming, the pilot light (6) of the selected
cooking zone blinks.
· When the timer has run down, there is a sound signal and
the timer display shows "00" statically, the assigned cooking
zone timer LED blinks. The programmed cooking zone will
be cut off and „H" will be displayed if the coking zone is hot,
otherwise a stroke will show in the cooking zone display.
