Description
Controls and Indicators
1
ROTOR Pressed to select the rotor in use. When ROTOR is pressed, the rotor type soft keys are
displayed ( JA: fixed angle rotors; JS: swinging bucket rotors; JLA: lightweight fixed angle
rotors; JV: vertical tube rotors; JE: elutriator rotors; JCF-Z: continuous flow/zonal rotors).
Pressing a rotor type soft key displays a list of the rotors of that type that can be used.
(Abbreviated rotors names are displayed.)
SPEED
Pressed to enter a run speed, in RPM or RCF

g . Use the
RPM
and
RCF
soft keys to toggle
between RPM and RCF setting modes, then enter the speed setting using the keypad. If
you enter a speed setting above the maximum RPM permitted for the installed rotor, an
error message will prompt you to select a speed within the rotor’s valid range, and will
display the range (in RPM or RCF).
If you do not specify a rotor and you enter a speed setting above the maximum permitted
for the installed rotor, and you start a run, during acceleration the centrifuge will identify
the rotor and reduce the speed setting to the maximum for the installed rotor.
TIME Pressed to enter run time (using the keypad). When TIME is pressed, the three time mode
soft keys are displayed:
HH:MM
(hour:minute),
W2T
(

2
t , accumulated centrifugal effect),
and
HOLD
. Pressing any of the soft keys causes the
TIME
display to flash, indicating that
a time can be entered on the keypad.
• Timed run (HH:MM) — Run time up to 99 hours and 59 minutes can be set. If more than
59 minutes are entered in the minutes field, the system automatically converts the
entry to hours and minutes. Decelerating begins when the set time counts down to
zero. The corresponding

2
t value can be displayed by pressing the W2T soft key.
•

2
t run — An

2
t value can be entered and the system will calculate the run time
required to reach that value. Valid

2
t settings are different for each rotor; a user
message will appear if an invalid entry is made. Deceleration begins when the
calculated run time counts down to zero, but

2
t continues accumulating until the
rotor stops spinning.
• Continuous run (hold) — For runs of unspecified lengths, hold mode is used. The display
will show the accumulated run time. When 99 hours, 59 minutes is reached, the
system resets to 0 and continues counting. The run will continue until the STOP key is
pressed.
TEMP
Pressed to enter run temperature (using the keypad), from –10°C to +40°C.
• The minimum allowable set temperature depends on the set speed and the rotor in
use. If a temperature is entered that cannot be achieved by the rotor at the set speed,
the TEMP°C field will flash.
•
The maximum achievable rotor temperature depends on the frictional heat generated
inside the chamber during operation. At low run speeds or low ambient temperature,
the centrifuge may not be able to achieve some higher temperatures.
• If, during acceleration, the system identifies a rotor different from the rotor entered by
the user, or if the set speed is changed during operation, the set temperature may
no longer be achievable. If this happens, the TEMP°C field will flash indicating that a
different temperature must be entered.
