4.1.1 Start-key
This key can be used for the following:
• starting centrifuge operation,
• terminating a previously started deceleration process and restarting
centrifuge,
• shifting into short-run at preselected speed. Pressing Start-key continuously
for longer than one second leads to acceleration to the maximum speed with
the maximum acceleration curve and after release deceleration with the
maximum deceleration curve.
The centrifuge can be started when
• the lid is closed
• the Start-key is illuminated.
4.1.2 Stop-key
This key can be used
• to early terminate a run: The centrifuge decelerates with the preset curve to a
complete stop. Deceleration can be terminated by pressing the Start-key
again.
• to carry out a faststop: Push Start-key for longer than one second. The
centrifuge decelerates with the maximum deceleration curve.
4.1.3 Lid-key
This key is used to open the lid. This can only be executed if
• the centrifuge has come to a complete stop
• the Lid-key is illuminated.
4.1.4 Knob
