Weissgauff HV 312 B [4/20] Protection against unintentional activation

After setting cooking stage “9“ Automatic parboiling is activated

by pressing at the right slider sensor. “A” appears on the display

imm ediately.

Now the required onboiling stage is selected via Slider area. The

“A” symbol appears after 3 sec. upon releasing the key -

alternating with the onboiling stage (500 msec. “A” and 1.5 sec.

onboiling stage).

The onboiling stage may be changed within 15 sec after

activation w ithout switching off the parboiling boost. Therefore,

the cooking zone is to be selected and the relevant cooking zone

is to be set afterw ards.

In case of a selection after 15 sec a lower cooking stage m ay be

set; automatic onboiling is switched off.

a higher onboiling stage may be selected; this leads to the

parboiling time being automatically brought in line with the

currently selected onboiling stage

Multi Circuit Activation (Optional)

The control unit may trigger – depending on the type – dual circuit

or triple circuit. M ulti Circuits are switched autom atically on after

activating a cooking zone.

Activation/Deactivation of dual circuit HL

By actuating the dual-circuit key “3” the respective double or

outer circuit is deactivated. Re-actuating the dual-circuit key “3”

activates the outer circuit again,

An active double or outer circuit is also shown by the assigned

LED “11” is statically illuminated.

Activation/Deactivation of triple circuit HL

For triple-circuit the following operation procedure is provided:

-By actuating the multi-circuit key “3” the respective double and

triple circuits of an active cooking z one are deactivated.

-Re-actuating the multi circuit key “3” activates the first outer

circuit and the assigned LED “11” illuminates again.

-A second actuation of the multi circuit key “3” activates the

second outer circuit and the assigned LE D “11” illuminates again.

Residual Heat

The determination of how long a cooking zone has residual heat

after operation and switch off – which may lead to burnings when

contacting – is calculated.

Status is calculated depending on:

Selected power stage (from “0” to “9”)

On/Off Time of the Relays

The residual heat indication of each cooking zone remains

activated until the calculated tem perature is smaller than + 60 °C.

Automatic Switch-off (Operating Time Limitation)

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 take 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 m sec. ON) and the error

code “E R 0 3” flashes on the display (0.5 s ON 0.5s OFF). If the

permanent actuation exceeds 10 sec., only the error code “ER

03“ keeps flashing as long as the m alfunction 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 w ait 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 O FF 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 sw itching 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 w ithout 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 sw itched off (power

sensor) and switched on again.
