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.
Protection against unintentional activation
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 malfunction (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).
Key Lock (Optional)
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 assigned key-lock LED "7" fades when switching off the
control The key-lock function included 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 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 LED fades. All sensor
keys may be operated as usual again.
Acoustic Feedback (Buzzer)
The following activities occurring during operation of the TC unit are fed
back audibly via a buzzer:
Short single tone for regular actuation of a key
Longer, intermittent tone for permanent use of keys over a longer period
of time (≥ 10 sec)
Expiry of the timer
Timer-function (optional)
The timer function is available in two types:
-Stand-alone-timer 1..99 min: Audible signal with timing. This function
can only be activated as long as no cooking zone is in operation (all
stages = 0). Is any cooking zone started with operation (level >0) than
the stand alone timer keeps in operation. If the timer shall be used to cut
off a cooking zone (see cooking zone timer) then the control must first be
switched off (power sensor) and switched on again.
-Cooking zone timer 1..99 min: This function can only be activated as long
as a cooking is active (stage < 0; display dot).
Audible signal with timing, four cooking zones to be cut off are freely
programmable.
Setting a timer value:
By adjustment with the slider area.
Primarily the adjustment of the first digit takes place and thereafter the
adjustment of the second digit.
Within 10sec after the adjustment of the second digit the value might be
reset. (Illuminated display dot in the timer display and in case of a cooking
zone specific timer a blinking assigned LED).
In case of an active timer display the timer value may be set to [0] directly
by pressing [0] on the slider area (left side)
Switching of an active timer:
A timer can be switched of by setting its value to 0.
A stand alone timer can be switched of by a double actuation of the power
key "1".
Timer Stand-Alone:
If the control unit is switched on (all cooking zone displays show [0]), the
stand-alone timer may be activated by pressing the timer select key. The
timer display show "00". The decimal dot on the timer display flashes. The
timer is cut off after 10 sec (black display) if no further settings are made.
In case of a timer value is set with no activation of a cooking zone within
10sec, the cooking zone displays are cut off (interposing relays are also
cut off). Possible optic warnings for hot cooking zones [H] are displayed
permanently As long as the timer is selected (display dot flashes for 10
sec) it can be set. The setting range is 0 -99 minutes in single steps;
by Slider area.
Directly after the timer value is set countdown starts with the last set
value. The timer is deselected automatically after 10 sec and the timer
display indicates the timer value. After expiring of the set time an acoustic
signal is given and the timer display flashes „00".
The acoustic signal is terminated
-after 2 min and/or
-by actuating any key.
Thereafter timer display stops blinking and extinguishes.
Possible optic warnings for hot cooking zones [H] are displayed
permanently
By pressing the ON/OFF key "1" , the control unit may be switched from
„purely timer operation" to cooking zone at any time -with or without an
activated Stand-Alone timer -.
Switching back to TC active mode with an active
Stand-Alone timer the timer is selected first (decimal dot on timer display
flashes). After a cooking zone is selected, the decimal dot disappears from
the timer display and a steady decimal dot on the cooking zone display
flashes on. When switching off the control unit by ON/OFF key "1" , the
Stand-Alone timer – if still in operation -is also switched off.
Cooking zone specific timer programming
Switching on the TC enables timer setting for dedicated cooking zones.
By actuating a cooking zone (cooking zone stage > 0) followed by
selecting the timer display (within 10 sec) a timer value may be assigned
to the cooking zone as a cut-off function. The LED around the timer "9"
indicates which cooking zone the timer had been activated for.
As soon as the timer is selected the according LED is blinking and the dot
in the timer display is flashing permanently. In case of a cooking zone is
selected thereafter, the dot extinguishes and the LED stops blinking.
When switching from one cooking zone to another, the timer display
indicates the current timer value of the respective cooking zone. Timer
settings of other cooking zones stay active.
Further setting is like with the stand-alone timer In case of more than
one active timer the display indicates the lowest timer value (after 10s
deselection time).
After expiring of the set time an acoustic signal is given and the timer
display flashes „00". The related timer LED is blinking synchronously. The
programmed cooking zone is cut-off, a permanent "0" is displayed and the
cooking zone is selected automatically. After 10 sec (deselection time) a
permanent "H" is displayed on a „hot"cooking zone. Otherwise, the symbol
"0" is indicated.
The acoustic signal and the blinking of the cooking zone timer Led is
terminated
- after 2 min and/or
- by actuating any key.
