2 .5 .4 Safety elements
Electronics
• The heating bath is equipped with a mechanical over-temperature protection.
The mechanical over-temperature protection consists of a bimetal thermostat that, in case of over-
temperature (over 260 °C), directly interrupts the power supply. It has to be set back manually
after the bath has cooled down (see also chapter 8).
The electronic over-temperature protection controls the temperature limit (actual bath temperature
may not exceed the given temperature by 2 °C for more than 2 minutes), the heating rate (actual
temperature may not rise by more than 5 °C during 5 seconds) and the function of the tempera-
ture sensor.
• The heating bath is equipped with safety fuses.
• The heating bath is equipped with a thermostatic control of the bath temperature - to prevent the
product from overheating
Parts in direct contact with the instrument
• Combi-Clips for fixing the evaporating flask and for safe removal of fixed ground-glass joints.
