Automatic Switch-off (Operating Time Limitation)
Protection against unintentional activation
Key Lock (Optional)
For each activated cooking zone a max. operating time is defined. The max. operating time
is depending on the selected cooking stage. After the expiration of the max. operating time
the cooking zone is automatically switched off. Each actuation of the cooking zone status
(changing the cooking level etc.) resets the count-down timer to the initial starting value.
Timer settings takes priority vs. operating time limitations for high cooking stage setting.
The electronic system cuts off automatically in case of an identified permanent use of keys
for about 10 seconds. The control unit releases an audible signal for 10 sec of the malfunc -
tion (period: 1000 msec, 500 msec ON) and the error code “E R 0 3” flashes on the display
(0.5 s ON 0.5s OFF). If the permanant actuation exceeds 10sec, alone the error code “ER
03“ keeps flashing as long as the malfunction occurs and is identified as such. In case the
cooking zone is at stage “hot“ the [H] symbol alternates with the error code (0.5 sec Symbol
0.5 sec “H“).
Water sprinkled on the glass surface does not always lead to a key actuation and cannot be
surely detected. ( After wiping the glass covering the keys, all keys are ready for operation
in no time).
If no cooking zone is activated within 20 sec after pressing POWER ON, the control unit is
reset to Off-mode (black displays).
The actuation of the key lock key “4” in the wait or active mode locks the keyboard and the
assigned key-lock LED “7” is statically illuminated. 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 as
-
signed key-lock LED “7” fades when switching off the control The key-lock function includ -
ed LED is active again when switching on (in wait mode 10 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 actuat-
ing 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 LED fades. All sensor keys may be operated as usual again.
