5.5 Monitoring function
5.5.1 Temperature monitoring
The appliance is equipped with a multiple overtemperature protection in accordance with
DIN 12 880. This serves to avoid damage to the chamber load and/or appliance in case of a
malfunction:
► electronic temperature monitoring (TWW)
► automatic temperature monitor ( ASF)
The monitoring temperature of the electronic
temperature monitoring is measured via a separate Pt100
temperature sensor in the working chamber. Temperature
monitoring settings are made via the
ALARM display. The
settings made apply to all operating modes.
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. 19 ). The type
of temperature monitoring triggered
(TWW in this example) is shown beneath
the temperature. If the acoustic alarm
has been activated in the menu mode
(
Sound, see page 57, indicated by the
speaker symbol in the alarm display), the
alarm is additionally signalled by an
intermittent acoustic signal, which can be turned off by pressing the confirmation key.
Information on what to do in this case are provided in the chapter Malfunctions, warning and
error messages on page 40.
Before reading how to adjust temperature monitoring (from page 35), please read the
description of the individual monitoring functions here.
