5. Choose YES to make the
system shut down at
maximum temperature, or
NO to allow the system to
run above maximum
temperature.
Your selection (YES or NO) appears to the right of the Max Temp:
field.
ENTERING ACCELERATION AND DECELERATION RATES
The centrifuge provides a choice of three acceleration rates and four
deceleration rates to protect the gradient and sample-to-gradient
interface. Table 3-1 describes these rates. If no rate is selected, the
centrifuge accelerates and decelerates at maximum rates.

Setting Description
Maximum acceleration Full torque is used from 0 rpm until set speed is reached.
Slow acceleration Approximately 2 minutes from 0 to 500 rpm. (The exact time depends on the mass of
the rotor in use; larger rotors take longer.) Above 500 rpm, full torque is used until set
speed is reached.
Timed acceleration From 0 to 500 rpm, acceleration can be set from 1 to 10 minutes Above 500 rpm, full
torque is used until set speed is reached.
Maximum deceleration Full brake from set speed to near 0 rpm. Reduced brake is used during the last few rpm
until 0 is reached to minimize sample disturbance.
Slow deceleration Reduced torque from set speed to 500 rpm, then approximately 2 minutes from
500 to 0 rpm. Deceleration to 500 rpm takes about twice as long as with maximum
deceleration. (The exact time depends on the mass of the rotor in use; larger rotors take
longer.)
Timed deceleration Full brake from set speed to 500 rpm. From 500 to 0 rpm, deceleration can take from
1 to 10 minutes (time is set by the user).
Off No brake is used. Rotor coasts from set speed to 0 rpm. Can take up to 1 hour,
depending on the mass of the rotor in use and the set speed.
