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.
Control of multiple circuits
When a dual / triple cooking zone is activated, the 3 circuits
are switched on at the same time. The activation / deactivation
of each circuit is done with button 3 and it is indicated with an
illuminated segment (11).
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 t wo 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 s witched 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.
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 off 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 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
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. Aft er 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
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 -.
Cooking zone specific timer programming
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.
In case of a cooking
extinguishes and the LED stops blinking.
When s witching 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. 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.
Thereafter timer display stops extinguishes and the cooking zone
stays unselected.
Behaviour of the cooking zone specific timer is similar to the
stand alone timer.
In case of a timer is programmed for a cooking zone the
operating time limitation is dependent of the timer value and not
of the standard table value.
