Level 1 (M I) Level 2
(M 2) Function Display
SOFT
Soft ramp: Reduce speed of acceleration and
braking ramp. Not used for short spin
centrifugation. On Rotor accelerates and brakes slowly.
Off Rotor accelerates and brakes rapidly.
LOCK
Key lock: Set the current centrifugation
parameters permanently to prevent the time,
temperature (only 5424 R) g-force (rcf) or
speed (rpm) from being unintentionally
modified. On Set the centrifugation parameters permanently.
When you select the keys time, temp (only
5424 R) and speed, the display shows SAFE.
Off
ATSET
Set start of centrifuging run time. On The set time is counted down only once 95% of
the specified g-force (rcf) or speed (rpm) has been
reached.
Off The set time is counted down immediately.
SHORT
Before the start of a short run (see Short spin
centrifugation on p. 26) it is possible to switch
between the maximum and currently set
g-force (rcf) or speed (rpm). The SOFT function
is not used for short spin centrifugation. MAX Short spin run at maximum g-force (rcf) or
speed (rpm) of the rotor used.
Set Short run at set g-force (rcf) or speed (rpm).
TEMP (only 5424 R)
Set the time limitation of continuous cooling
(see p. 24). 8 h Preset value.
oo Endless operation of continuous cooling.
Icing possible! Note that this may reduce the
service life of the compressor.
ALARM On Switch on loudspeaker.
Off Switch off loudspeaker.
VOL VOL1
...
VOL5 Adjust the speaker volume in 5 steps. The loud-
speaker must be switched on for the adjustment to
be audible.
SLEEP
Standby mode On If the centrifuge has not been used for 15 min and
the standby mode has been switched on, it
switches to standby mode. The EP logo then
appears in the display. When a button or knob is
used or the centrifuge lid is closed, the centrifuge
is reactivated. It is then ready for operation.
Off Standby mode deactivated.
LID (only 5424)
Lid release, from software version 2.2. AUTO The centrifuge lid opens automatically after
centrifugation.
Off The centrifuge lid must be manually opened with
the open key after centrifugation.
