3.5 Safety features
3.5.1 Overheat cut­out
To protect against overheating, the heating bath has a thermostatic bath temperature
control.
In addition it is fitted with an electronic and a mechanical overheat cut­out.
The electronic overheat cut­out monitors the temperature limit (the actual temperature
of the bath must not exceed the specified temperature by more than 2 °C for longer
than 2 minutes) the heating rate ( the actual temperature must not increase by more
than 5 °C within 5 seconds) and the function of the temperature sensor. If the elec­
tronic overheat cut­out trips, the device should be inspected by a BUCHI service tech­
nician.
The mechanical overheat cut­out consists of a bi­metallic thermostat that immediately
cuts off the power supply at high temperatures (above 145 °C). The mechanical over­
heat cut­out has to be manually reset once the heating bath has cooled down (see
Chapter 8.2.1 "Resetting overheat safety cut­out", page 44).

The heating bath is equipped with fuses to protect against electrical overload.
The rotary drive unit has an electrical overload cut­out.
