Any malfunctions during operation will be identified by an error message on the display.
Once a serious error message has been displayed, the lift moves to the top end position and the device can no longer be operated. The lift can be
operated again.
Proceed as follows in such cases:
 Switch off device using the main switch
 Carry out corrective measures
 Restart device
Error Effect Cause Correction
Communication Distillation cancelled in IR interface obstructed - Press ESC to confirm
error bath "Auto-distillation" mode Heating bath switched off - Switch on heating bath
- Check and clean IR interface
No rotation Distillation stopped, Rotary drive does not start or - Switch device off and on at mains switch
no rotary drive exhibits very large speed variation
No temperature Distillation cancelled in No differential temperature increase - Press ESC to confirm
difference "Auto-distillation" mode of cooling water - Check flow of cooling water
- Check that the cooling water hoses are fitted correctly
Temperature Distillation stopped Differential temperature outside - Press ESC to confirm
out of range measurement range (> 7 K) - Check that the cooling water hoses are fitted correctly
No vacuum Distillation stopped Vacuum target value not reached - Press ESC to confirm
Vacuum cannot be controlled - Check that the glassware and hose connections
are properly sealed
- Switch on the pump
- Check the solenoid valve connections
No venting Vacuum cannot be vented No venting of condenser - Switch off the device
- Vacuum sensor faulty
- Manually vent the glassware using the stop
valve
Water valve Water runs continuously into Water valve not closed - Press ESC to confirm
not closed cooling circuit - Check the connection
Flow rate Distillation cancelled in Flow rate of cooling water out of range - Press ESC to confirm
out of range "Auto-distillation" mode - Readjust flow rate
- Switch off flow rate control (for dry ice coolers)
Condenser Distillation stopped Condenser overload - Press ESC to confirm
overload Distillate may be able to enter the - Change process parameters, e.g.
vacuum pump - Increase pressure
- Reduce bath temperature
- Increase condenser flow rate within specified range
Distillation Distillation stopped The system detected that there was - Press ESC to confirm
dry no more medium in the evaporating - Alternatively, activate the “Drying” option
flask during the distillation. in the “Settings” menu
Lift not in Distillation stopped Obstruction in path of lift - Press ESC to confirm
end position Lift motor switches off - Check the path of the lift.
- Remove any obstructions.
Calibration error Calibration reset to factory setting Out of calibration range - Press ESC to confirm
(max. +/-0.5 K) - Check that the sensor is connected correctly
- Carry out a new calibration procedure
Memory error Calibration parameter for vacuum reset Error by checking contents of memory Vacuum must be recalibrated
to factory setting
Vacuum leak Distillation stopped Leak in vacuum system Press ESC to confirm
Locate leak
