3. 4. Centrifugation
Mind the safety zone of minimum 30 cm around the centrifuge. Refer to “Info & Health Status Area” on page
3-2. Persons and hazardous substances must be kept out of this safety zone while centrifuging.
Once the main switch has been turned on, the rotor has been properly installed, the setpoints have been set as
explained in the previous section, and the centrifuge lid has been closed, you are ready to start.
You have various options to start a centrifugation run:
ƒ
Continuous Mode: This is a fully manual mode. If you have chosen “Continuous Mode” instead of a preset
runtime (see
“Set Run Time” on page 3-8 ), use the Start button and Stop button to start and stop
centrifugation manually, as explained in the section “Run in Continuous or Timed Mode” further below.
ƒ
Timed Mode: This is a semi-automatic mode that relies on a timer. If you have preset a runtime (see “Set
Run Time” on page 3-8 ), tap the Start button , then and wait for the timer to expire and the centrifuge
to stop automatically, as explained in the section “Run in Continuous or Timed Mode” .
ƒ
Pulse Mode: This is a short-run centrifugation mode with selectable behaviors. You choose a behavior,
then tap the Pulse button and wait for the centrifuge to run and stop automatically, as explained in the
section
“Run in Pulse Mode” on page 3-13.
ƒ
Program Mode: This is a fully automatic mode. You prepare and save an automated program, then run it
from the touchscreen, as explained in the section
“Automate Processes Using Programs” on page 3-20 .
WARNING Damage to health from centrifuging explosive or flammable materials
or substances.
Do not centrifuge explosive or flammable materials or
substances.
Run in Continuous or Timed Mode
Proceed as follows to run the centrifuge in continuous or timed mode:
1. Press the Start button on the “Home” screen.
The Start button turns into the Stop button .
The centrifuge starts running and the touchscreen shows the parameters increasing towards their setpoints.
After one minute of continuous running without any intervention by the user, the touchscreen goes to
lighthouse mode. In lighthouse mode the touchscreen shows the basic settings, like current speed and
speed setpoint, rotor and bucket type, run time elapsed (or remaining) and run time setpoint (timed runs
only), plus a progress bar for the run, and the Stop button .

2. Depending on the time mode you have chosen (see “Set Run Time” on page 3-8 ), do one of the following
to stop the centrifuge:
a. Continuous mode: Press the Stop button on the Home screen when you have finished centrifuging.
b. Timed and ACE modes: Wait until the timer expires and the centrifuge stops automatically, or press the
Stop button on the “Home” screen to abort the centrifugation run prematurely.
3. When the centrifuge has stopped centrifugation completely, press the Open button on the control panel
to open the lid.
The lid pops open, and the Open button is surrounded by a light gray border now to indicate that the lid
is unlocked.
NOTICE You cannot open the lid as long as the centrifuge is spinning.
