Operation
Programmed Operation
a.
(Press
STOP
to terminate a run for any reason.)
•
The green light next to the
STOP
key will flash while the rotor decelerates.
•
A tone sounds when the rotor comes to a complete stop.
—
(Instructions for disabling the tone are at the end of this section.)
2
After the rotor has stopped and the LED by the door key lights, press
DOOR
.
•
The door opens.
3
Remove the rotor (or containers).
CAUTION
If disassembly reveals evidence of leakage, you should assume that some fluid
escaped the rotor. Apply appropriate decontamination procedures to the
centrifuge and accessories.
NOTE
Depending upon the duration of the event, transient power-line interruptions may cause this
equipment to decelerate or reset with the possible loss of in-process operation. If you suspect this has
occurred, simply repeat the runs.
Pulse Function
The pulse function, accessed by pressing the
PULSE
key, is used for short-duration runs as follows.
•
When the
PULSE
key is pressed, the rotor accelerates at maximum rate to the set speed and
continues to spin as long as the
PULSE
key is pressed. (The current run time, acceleration, and
deceleration settings are overridden by the pulse function.) When the
PULSE
key is released,
the rotor begins decelerating to 0 RPM using maximum deceleration. Using the pulse function
eliminates the need to press the
START
and
STOP
keys.
•
When the
PULSE
key is pressed, the
TIME
display begins displaying the elapsed seconds. When
the
PULSE
key is released, the seconds stop accumulating.
•
The centrifuge memory retains the parameters of the last run performed before the
PULSE
key
was pressed. At the end of a pulse run, after the centrifuge door is opened and closed the
previous run parameters are displayed.
Programmed Operation
The instrument internal memory can store up to 10 programs which can be recalled by keypad
numbers 0 through 9. Saved programs are retained in memory even if the power is turned off.
Procedures for entering run parameters are the same for programmed operation as those described
above for manual operation.
