28 Appendix
If two values are given, the third value is determined by the equation. If the speed or
the rotation radius is changed, the resulting RCF will be recalculated. If the RCF is
altered, the speed under consideration of the radius is adapted accordingly.
r = radius in cm
n = speed in rpm
RCF without dimension
If the density of the liquid is higher than 1.2 g/cm
of the centrifuge is calculated according to the following formula:
Rho = density in g/cm

Most of the errors can be reset by pressing power off | on. In the event of a short
power failure during a run, this run is interrupted and can be continued by opening
the lid and pressing the "Start | Stop" key.
No indication on the display
No power in the socket?
Power cord plugged in and line voltage present?
Power switch on?
Lid closed?
Set speed remains in the display:
Centrifuge displays an error 1 to
18 after power on again.
Error 19
In the event of a power failure, it is possible to manually open the centrifuge lid with
a socket wrench (included in the scope of supply). The opening is located in the bot-
tom plate in the front quarter on the left-hand side.
The lid may only be unlocked and opened when the rotor is at a standstill.
If the lid is opened via the emergency lid release during a centrifuge run, the
centrifuge will be switched off immediately and decelerate without a brake.

Actions
Check fuse in mains supply.
Plug in power cord correctly.
Switch on power.
Close lid.
Power off | on. If error occurs again, call service.
Open and close the lid again. If error occurs again
although the lock is bolted, call service.
Power off | on. If error occurs again, call service
(please refer to chapter 10.4.1 Error Codes).
Confirm by pressing the lid-key.
