Monitoring function
5.6.1
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)
►
mechanical temperature limiter (TB)
The monitoring temperature of the electronic temperature
monitoring is measured via a separate Pt100 temperature sensor
in the interior. 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 on the tempera-
ture display: the actual temperature is
highlighted in red and a
warning
symbol is shown ( Fig. 16 ). The type of
temperature monitoring triggered (TWW in
this example) is shown beneath the
temperature.
If the acoustic alarm has been activated
in menu mode (
Sound
see page 52,
indicated by the speaker symbol
on the
alarm display), 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 if this happens can be found in chapter Malfunctions,
warning and error messages from page 37.
Before reading how to adjust temperature monitoring (from page 32), please read the
description of the individual monitoring functions here.
Electronic temperature monitoring ( TWW)
The manually set monitoring temperature
min
and
max
of the overtemperature control is
monitored by an adjustable over/undertemperature controller (TWW) of protection class 3.3
according to DIN 12 880. If the manually set monitoring temperature
max
is exceeded, the
TWW takes overtemperature control and begins to regulate the monitoring temperature (Fig.
17).
