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.
Locking systems
◊ Key lock:
The actuation of the key lock key "7" in the wait or active
mode locks the keyboard a key symbol appear in the
displays "8":
siguiente:
Here, the actuation times of the key-lock key have to be
taken into account. The control continues to work in the
set mode, but may no longer be operated with any key,
except the key-lock key itself or the on/off key "1".
The switching OFF with the on/off key "1" is also possible
in the locked condition. The lock symbol in display "8"
fades when switching off the control. The key-lock
function included the lock symbol in display "8" is active
again when switching on (in wait mode 20 s) until this
is deactivated by a repeated actuation of the key-lock
key. The activation/deactivation of the key-lock function
in the off mode is not possible. When programmed timers
expire the respective timer alarms may be confirmed by
actuating any key without needing to unlock the control.
The repeated actuation of the key-lock key in the wait
or active mode unlocks the keyboard and the assigned
key-lock symbol fades. All sensor keys may be operated
as usual again.
◊ Child safety feature:
Activating the child 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.
