4.13 Security functions
Zone switch off security
The hob must switch off a zone automatically which has been activated for an unnecessary long
time. If this time has elapsed the power board the hob must switch off this zone. The information of
elapsing time comes from the power board by a „hob control status message“.
Wrong activations of buttons
In practice it is possible that the keys could be covered e.g. by a pot. This can cause e.g. wrong
zone activation. Therefore if any key has been pressed longer than 10 seconds the hob must be
switched off. This event must be signalised to the user by a special buzzer signal.
Hot zone signalisation (Residual heat indication)
The hob must show the user if a zone is still hot after being switched off. This information comes
from the power board by a „hob control status message“. If the zone is off and hot this must be
shown by an „H“ in the zone level display.
Hob switch off security
The hob must switch itself after 10 seconds if no cooking level or clock has been set during this
time.
