Preselections
☞
The selection of the parameters is carried out via the selection knob.
☞
Set vacuum (lower switch-off value): If the pressure drops below the ”Set vacuum” a time-meter
starts running. The time-meter is reset, if the pressure exceeds the pressure value for switching on
again (”Switch on”). If the ”Set vacuum” is not reached within 100 hours the controller signalizes a
fault.
The ”Set vacuum” is adjustable in a range of 1 - 1060 mbar.
☞
Switch on: If the pressure exceeds the pressure for switching on, pumping down starts again.
The ”Switch on” pressure is adjustable in range of 1 - 1060 mbar.
In case of sudden high pressure increase pumping starts even if the ”Switch on” pressure is not
reached (pressure increase control).
☞
Delay: If the time since the vacuum was below ”Set vacuum” and ”Switch on” levels is longer than
”Delay” the pump is stopped. Pump is started again if the pressure increases rapidly or if the ”Switch
on” level is exceeded.
The delay is adjustable in a range of 1-300 minutes and to ”Off”.
The screen-shot shows the factory-set values.
When ”Graphic” is selected the display shows a pressure over time curve (right screen-shot).
The timeline in the diagram adapts automatically to the process time.

Press the selection knob twice to return to the standard display.
