Operation and control
5.5.2 Mechanical temperature monitoring: Temperature limiter (TB)
The appliance is equipped with a mechanical temperature limiter (TB) of protection class 1 in
accordance with DIN 12 880.
If the electronic monitoring unit should fail during operation and the factory-set maximum
temperature is exceeded by approx. 20 °C, the temperature limiter, as the final protective
measure, switches off the heating permanently.
5.5.3 Function
If temperature monitoring has been
triggered, this is indicated by the
temperature display: the actual tempera-
ture is highlighted in red and a warning
symbol
is shown (Fig. 18 ). The type
is shown (Fig. 18 ). The type
of temperature monitoring triggered is
shown beneath the temperature: TB for
mechanical and TWW or TWB for
electronic temperature monitoring. The
alarm is additionally signalled by an
intermittent acoustic signal, which can
be turned off by pressing the confirma-
tion key. Information on what to do in
this case are provided in the chapter
Malfunctions, warning and error
messages from page 30.
5.6 Ending operation
Warning!
Depending on the operation performed , the surfaces in the working
chamber and the chamber load may still be very hot after the appli-
ance is switched off. Touching these surfaces can cause burns. Wear
heat-resistant protective gloves or wait until the appliance cools
down. To do so, pull the handle bar until the door springs open into
its ventilating position (see page 22).
1. Switch off active appliance functions
(turn back the set values).
2. Remove the chamber load.
3. Switch off the appliance Fig. 19 ).
