/// Setting the safety temperature
Safety circuit
The adjustable safety circuit prevents the temperature of the heating bath from getting too high
as a result of:
- a controller error,
- the rotating/pressing knob having been accidentally turned�
Once the safety temperature has been reached, the device switches off permanently�
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 appears and the heating bath is switched off permanently� To remedy this error, see “Error
codes”�
When the safety circuit is set, an upper temperature limit between 50 and 190 °C is defined�
� Silicone oils as tempering media
When increased safety is not necessary the temperature of the safety circuit stays at 190 °C�
Temperature of the tempering medium rises to a maximum of 190 °C in the case of an error�
Then the safety circuit switches the heating bath permanently off�
� Demineralised water as the tempering medium
When increased safety is not necessary, the adjustment knob of safety circuit stays all the way
to the right� As long as there is any demineralised water in the heating bath, the temperature
of the tempering medium rises to a maximum of 100 °C, in the case of an error� If the water is
evaporated completely, the temperature of the tempering medium rises to a maximum of 190
°C� Then the safety circuit switches off the heating bath permanently�
� Temperature-sensitive or easily flammable media in the rotary evaporator
When the pre-set bath temperature may not be exceeded under any circumstances set the
safety temperature as described below�
Adjusting the safety temperature
- Set the desired safety temperature by turning the rotating/pressing knob within the 5 seconds of
the “SAFE TEMP�“ appearing on the display after the device is switched on� (Fig� 5)
Checking the safety circuit
- The safety circuit has to be checked by the user once a year�
- Fill the heating bath with 1 liter of water as tempering medium�
- Set the safety temperature to 100 °C�
- Set the set temperature to 80 °C�
- Start the heating function by pressing the rotating/pressing knob�
- When the set temperature is reached, turn the heating bath off and on again at the mains
switch�
- Set the safety temperature to 70 °C�
- The medium temperature is thus 10 K above the safety temperature, the safety circuit trips, the
display shows E24� (Fig� 7)

19
/// Controlling the medium temperature
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 180 °C by turning the
rotating/pressing knob� The max� medium temperature setting is the safety temperature minus
10 °C�
- Start the heating function by pressing the rotating/pressing knob�
- An animated heating symbol appears on the display� (Fig� 9)
- The heating bath is heated up to the set temperature�
- The set and actual temperature referred to the medium are shown on the display� (Fig� 9)
Select tempering medium
- If a target value > 90 °C is set, the PID controller is adapted specially for oil�
- The “OIL“ symbol appears on the display� (Fig� 11)
- If the target value is reset to 20 °C the PID controller is adjusted again specially to water�
- The “OIL“ symbol will disappear from the display� (Fig� 9)

/// Key “Lock“
/// IR interface
The operating settings can be locked by pressing and holding the key for 2 seconds, preventing
any inadvertent changes during operation� The lock symbol appears on the screen when this
function is activated� (Fig� 10)
Press and hold the key again for 2 seconds to unlock the operating settings� The lock symbol dis-
appears when function is deactivated�
Data transfer via IR interface
The heating bath transfers data via IR interfaces� These interfaces are located on the left display
side of the heating bath or on the right side of the drive unit� Do not place any objects between
the two operating units as otherwise the data transfer may be interrupted!
Remote Mode
Using the laboratory device software “labworldsoft
®
” and the rotary evaporator RV 10 digital/
control the device can be operated in “Remote” mode� In this mode, the device can no longer be
hand-operated� (Fig� 12)
Note: Please comply with the system requirements together with the operating instructions and
help section included with the software�
