4. 3. Programs
To reduce the setup effort before a centrifugation run, the centrifuge lets you enter a selection of desired program
parameters and store them together as a program that may be retrieved for later use. You can include all or part
of the run parameters explained in previous sections of this chapter, including:
ƒ
acceleration and braking profile
ƒ
speed or RCF value
ƒ
running time
ƒ
temperature
ƒ
bucket type by code
Setting Up and Saving a Program
All centrifuge models described in this section let you store up to six programs using dedicated front panel keys.
You can retrieve and start the programs later on by pressing the program key assigned during storage.
Proceed as follows to store a program:
1. Set your choice of run parameters in one go, as explained for your centrifuge model in the previous sections
of this chapter.
2. Press any of the program selection keys
Program 1
for 4 seconds.
Your program is stored now.
For instructions on how to start a previously stored program, please refer to the section “Program Mode
Operation” on page 4-7 .
4. 4. Centrifugation
Mind the safety zone of minimum 30 cm around the centrifuge. Refer to “Figure 1–1: Safety Zone” on page 1-2 .
Persons and hazardous substances must be kept out of this safety zone while centrifuging.
Once the rotor has been properly installed, the main power switch has been turned on and the centrifuge lid has
been closed, you are ready to start centrifuging.
You have various options to start a centrifugation run:
ƒ
Continuous Mode: This is a fully manual mode. In Continuous Mode you use the Start key
Start
and Stop
key
Stop
to start and stop centrifugation manually, as explained in the section “Continuous Operation”
further below.
ƒ
Timed Mode: This is a semi-automatic mode that relies on a timer. If you have preset a runtime (see “4.
2. 2. Set Run Time” on page 4-3 ), you press the Start key
Start
, then wait for the timer to expire and the
centrifuge to stop automatically.
ƒ
Program Mode: This is a fully automatic mode. You prepare and save an automated program, as
explained in the section
“Setting Up and Saving a Program” on page 4-6 , then run it by pressing the
appropriate program selection key
Program 1
.
WARNING Damage to health from centrifuging explosive or flammable materials
or substances.
Do not centrifuge explosive or flammable materials or
substances.
Continuous Mode Operation
Proceed as follows to run the centrifuge in continuous, manual stop mode of operation.
1. Set the desired parameters, as explained in the section “4. 2. Set Basic Centrifugation Parameters” on page
4-2 .
NOTICE Speed (see “4. 2. 1. Set Speed / RCF-Value” on page 4-2 ) must be set as a minimum
requirement.
2. Press the Start key
Start
on the control panel.
The centrifuge starts running up to the pre-set speed. The LCD display changes to reflect the acceleration
process until the centrifuge reaches the pre-set speed.
When the centrifuge has accelerated to the pre-set speed, the timer starts counting the elapsed time.
3. Press the
Stop
key
Stop
when you have finished centrifuging.
NOTICE You cannot open the lid as long as the centrifuge is spinning.
