INSTRUCTION MANUAL
3.15 FAST COOL FUNCTION
By pressing the FAST COOL key, you turn on the fast cool function. The key lights
up. START key lights up also. The program display shows FC (fast cool). Rotor
RA 24/2 and RA16/5 starts to run automatically with 8,000 RPM. Fast cool
function cools down the centrifugal chamber to the set temperature. When the
temperature is reached, display for rotational speed shows message READY, and
the light for the FAST COOL key turns off. Rotor keeps on running and START
key is still lit, until you stop the centrifuge by pressing the STOP key. If you don't
stop the centrifuge manually, fast cool function turns off automatically after 1 hour.
NOTE:
If maximum speed of inserted rotor is lower than 8,000 RPM, the rotor will be running with the
maximum allowed speed for that rotor.
3.16 RESET OF LID LATCH
By pressing and holding the LID key, you set the lid latch to initial position. This is
needed in the case of power failure during the opening of the lid, when lid latch
motor stops in undefined position. When power returns, it could happen that you
can't open or close the lid. If this happens, press the key for approximately two
seconds, until you hear the sound of lid latch motor, then release it. After that, you
will be able to open and close the lid normally.
3.17 AUXILIARY LID RELEASE
In case of power failure, the lid can be opened manually. If power failure occurs during the operation
of the centrifuge, the rotor may continue rotating for several minutes, before it stops.
Before auxiliary lid release, turn off the main switch of the centrifuge and wait until
rotor fully stops. Check this by looking through the lid window. Otherwise, injury
from rotating rotor may occur!
On the underside of the centrifuge, by the front left foot, there is a plastic plug, which you pull out of
the hole. There is a string fastened to the plug. Pull the string to open the lid of the centrifuge. Then
insert the string and the plug back in the hole.
3.18 AUTOMATIC BRAKING AFTER POWER RESTORATION
If power failure occurs during the operation of the centrifuge, the rotor may continue rotating for
several minutes, before it stops. When power returns, the centrifuge checks if the rotor is still rotating.
If it is still rotating then the display shows message Error brX (X is a number from 0 to 9 and
represents the set braking level). The centrifuge begins with the automatic rotor braking, which is
performed with preset braking level. When rotor stops, display shows error message MAINS INT and
thus warns you, that power failure occurred during operation and the centrifugation was interrupted.
By pressing the STOP key, you exit from error display and go back to stand-by mode. You can use
the centrifuge again.
