The runtime is considered faulty if the centrifugation run had to be stopped
prematurely.

NOTE
If the centrifugation monitoring system is used in combination with free
acceleration or deceleration curves, unjustified error messages may result
in certain cases.
Spin-
out from…
If this function is active, the drive will be disconnected if the actual speed is
below the set speed. As a result, the rotor decelerates and stops in a
brakeless manner.
HINWEIS
A spin-out, in particular with heavy rotors and at high speeds, can take a
lot of time! (Depending on the rotor and load, the speed will be reduced by
approximately 0.5 to 1 rpm per second.)
If the spin-out is active, "+0" is displayed next to the deceleration curve.
• The spin-out can be interrupted by a quick stop or by restarting the
centrifuge.
Lock
In order to prevent any unauthorised use of the centrifuge, the following
functions can be blocked:
• Saving of programs (level 01)
• Changing of parameters, short run (level 02)
• Loading of programs (level 03)
• Start button (level 04)
