Operation
ENTERING RUN SPEED
Enter a run speed up to the maximum speed of the rotor in use
(21 000 rpm maximum). Or, enter a relative centrifugal field (RCF)
value up to the maximum achievable RCF of the rotor.
Action
Result
1. Press [
RPM/RCF
] once to enter
speed in RPM or twice to
enter speed in RCF.
Allowed speed for the selected rotor is displayed.
2. Use the keypad to enter
required speed.
Entered speed appears on the speed display. (If the entered speed is
higher than the rated speed of the installed rotor, a message showing
the valid speed range will be displayed. Press [
CE
] and enter an
acceptable value.)
3. Press the next run-parameter
key or [
ENTER
].
You can change the set speed at any time by repeating steps 1
through 3. The rotor will accelerate or decelerate to the new speed.
➠
NOTE
During acceleration, the instrument identifies
the rotor and checks its maximum allowable
speed. If set speed is greater than the rotor
group’s maximum allowable speed, the rotor
will decelerate to its rated speed, and an error
message will be displayed. Refer to Section 4,
TROUBLESHOOTING
.
ENTERING RUN TIME
Run time can be set for up to 99 hours and 59 minutes or for a hold
(continuous) run. The time display begins counting down when the
rotor starts to spin. For a timed run, the run automatically terminates
when the set time reaches zero; a tone sounds when the rotor has
stopped. For a hold run, the elapsed time is displayed and the run
continues until [
STOP
] is pressed.
