Automatic mode
Switching on the automatic mode
➨ Press key MODE.
☞ ”Auto” is displayed.
☞ After starting process control, the pressure is adapted to
the process automatically: The controller determines the
boiling point and adapts if the boiling pressure changes.
☞ If automatic mode is switched on while process control is
active, the process pressure is adapted.
Setting the maximum speed:
Set the value for the speed by using key
▲ or ▼ (effective
only if the process pressure is adapted):
☞ To activate set mode: Press key shortly. The current speed
is displayed for one second.
☞ With a second tip within one second or continuous press-
ing:
☞ Set speed. The new set point is stored when the key is re-
leased.
☞ The reduced maximum speed restricts the evaporation rate
in case of low boiling solvents and a carry over of sub-
stances.
☞ The utilisation of a condenser or a cold trap at the inlet can
be optimised.
☞ ☞ ☞ ☞ ☞ If selecting ”HI” (recommended) for motor speed, the
maximum speed for automatic adaptation of the motor
speed is restricted to a value corresponding to the sys-
tem size.

If automatic switching off was preselected and the controller
has determined that evaporation is completely finished:
☞ ”Auto” is flashing.
☞ The pump is switched off. If the controller measures a pres-
sure > 1060 mbar, the pressure is reduced to 1060 mbar to
avoid overpressure.
☞ The controller is still active, the control must be finished by
pressing key START/STOP or by venting (the coolant valve
will not be closed until then and until the after-running time
has elapsed).
To use the advantages of the automatic mode optimally, switch
on ”Auto” before starting the process.
☞ Switching on automatic mode: Press key MODE.
☞ The controller determines the operating pressure.
☞ When activating the automatic mode if process control is
active (after having pressed key START/STOP) the actual
pressure is stored as set point and adjusted automatically.
Switching off the automatic mode
➨ Press key MODE.
☞ Switching off the automatic mode is possible at any time.
☞ ”Auto” disappears.
☞ While vacuum control is active the actual pressure is stored
as new set point.
