/// Safety temperature
/// Controlling the medium temperature
The safety circuit prevents the temperature of the heating bath from getting too high as a result
of controller error� Once the safety temperature has been reached, the device switches off per-
manently�
Furthermore, dry running of the heating bath is detected� The device switches off permanently�
The dry running function detects both accidental heating of the heating bath without liquid and
dry running caused by water evaporation starting at a set temperature of 60 °C� The error message
E26 (Fig� 11) appears and the heating bath is switched off permanently� To remedy this error, see
“Error codes”�
The medium temperature is limited by the set safety temperature controlled by means of a PID
controller and measured by the PT 1000 temperature sensor, and the medium is heated up as
quickly as possible without overshooting to the set temperature�
The PID controller adapts to the different tempering media and ensures optimum temperature
control with minimum temperature drift and fluctuation�
Optimum control is only achieved when the medium is mixed using a rotating evaporator piston�
�
Set the desired medium temperature between room temperature and 99 °C by turning the
rotating / pressing knob�
�
Start the heating function by pressing the rotating / pressing knob�
�
The LED heating appears�
�
The heating bath is heated up to the set temperature�
�
The set and actual temperature referred to the medium are shown on the display�
