Changing settings during the centrifugation run.

The running time, the speed, the relative centrifugal force (RCF/RZB), the run-up and run-down parameters as well
as the temperature can be changed while the centrifuge is running.
The parameters can only be changed one at a time and in succession.

Select the desired parameter and change the value using the control knob


Press the key. The modified setting will be stored in program location "----" (see Chapter "Automatic

buffer"). The original program will not be overwritten.
18 Integral RCF (∫RCF)
The integral RCF (∫RCF) is a measure for the sedimentation effect (∫ n
centrifugation runs. To interrogate the integral RCF, press and hold the

Emergency stop


Press the key twice. The STOP symbol will flash in the display.
STOP
In the case of an emergency stop, run-down takes place with braking step R9 (shortest run-down time). If braking
step R0 was selected, the run-down time will be longer than with braking step R9 for technical reasons.

Audible signal

The audible signal sounds in accordance with the following philosophy:
OFF 
at 2 s intervals on the occurrence of a fault
ON1 
at 2 s intervals on the occurrence of a fault

at 30 s intervals on completion of a centrifugation run and the rotor coming to rest.

ON2
at 2 s intervals on the occurrence of a fault

at 30 s intervals on completion of a centrifugation run and the rotor coming to rest.

every time a key is pressed
The audible signal is silenced by opening the lid or pressing any key.
The signal can be set as follows when the rotor is at standstill.

Open the lid.

Press and hold the key for 8 seconds.

Set the desired function (OFF, ON1, ON2) by means of the control knob

Press the key to save the setting.

Interrogating the operating hours

It is only possible to interrogate the operating hours when the rotor is at standstill.

Open the lid.

Press and hold the key for 8 seconds.

After 8 seconds SOUND / BELL XXX will be displayed.

Press the key once more.

The operating hours (CONTROL: ) for the centrifuge will be displayed.
The operating hours display will go off automatically after 10 seconds.
