Description
The centrifuge has two acceleration profiles: MAX—maximum
acceleration from 0 rpm to set speed, or SLOW—slow acceleration
from 0 to 500 rpm, followed by maximum acceleration to set speed.
The [
ACCEL
] key is used to select the maximum acceleration or slow
acceleration, provided to maintain optimum separation.
The centrifuge has three deceleration profiles: MAX—full dynamic
braking to 0 rpm; SLOW—brake to 500 rpm followed by reduced
braking to a gentle stop; OFF (coast from set speed to stop). The
[
DECEL
] key is used to select the deceleration rate provided to main-
tain optimum separation.
A toggle switch used to enter into and exit out of the program mode
to create or recall programs. When the key is pressed, the program
number can be selected using the keypad.
Saves the program in memory after program run parameters have
been entered.
The keypad is used to enter numerical run parameters, to enter or
recall a program number, and to select acceleration and/or decelera-
tion rates. In addition to keys 0 through 9, the keypad includes plus or
minus/decimal key and a [
CE
] (clear entry) key.
The [
± .
] key is used to enter a temperature setting below 0°C (for
example, –2°C), or to enter a decimal point in a rotor entry code,
depending on the parameter key selected.
The [
CE
] (clear entry) key clears any parameter on the display.
Pressing [
CE
] will also clear some diagnostic messages. If a
diagnostic message does not clear when [
CE
] is pressed, see Section 4,
TROUBLESHOOTING
.
The [
ENTER
] key can be pressed to save parameter inputs to system
memory during manual run setup, and to start the centrifuge ([
ENTER
],
then [
START
] must be pressed to start the centrifuge).
