Query of operating hours and the number of centrifugation runs

The operating hours are divided up into internal and external operating hours.
Internal operating hours: Total time the device was switched on.
External operating hours: Total time of previous centrifugation runs.
The operating hours and the number of centrifugation runs can be queried as follows when the rotor is at standstill:
•
Keep the key held down for 8 seconds.
PROG
After 8 seconds, ∗∗∗ Machine Menu ∗∗∗ appears in the display.
•
Press the key as often as necessary until the -> Operating Time is displayed.
PROG
•
Press the key. The external operating hours are displayed, e.g. OP Time ext = 0h25m.
START
•
Press the key. The internal operating hours are displayed, e.g. OP Time int = 1h36m.
PROG
•
Press the key. The number of centrifugation runs is displayed, e.g. Number of Starts = 10.
PROG
•
Press the key twice to leave the menu, "Operating Time" or press the key
OPEN / STOP
to leave the "Machine Menu".

Querying system information

Rotor information and the program version of the centrifuge as well as the frequency converter can be queried as
follows when the rotor is at a standstill:
•
Keep the key held down for 8 seconds.
PROG
After 8 seconds, ∗∗∗ Machine Menu ∗∗∗ appears in the display.
•
Press the key as often as necessary until the ->Info is displayed.
PROG
•
Press the key. The rotorcode (rotor), the maximum rotor speed (Nmax) and the preset centrifuging radius

(R) of the last rotor that was recognized by the rotor recognition , e.g. Rotor 4∗: Nmax = 4500 R=184.
The last recognized rotor is marked with a star (∗). Use the adjusting knob
permitted in the centrifuge displayed.
•
Press the key. The program version of the centrifuge is displayed, e.g. SW version = 01.00.
PROG
•
Press the key. The program version of the frequency converter is displayed e.g. FC-SW-Version = 4.
PROG
•
Press the key twice to leave the "Info" menu or press the key

Immediate display of centrifugation data after switch-on.

• Switch on the power supply. (Switch setting Ι).
•
The first time the display changes optically, (inverse display) press any key and keep it held down. The
centrifugation data is displayed immediately.

Cooling (only in centrifuges with cooling)

The temperature set-point can be adjusted from -20°C to +40°C / -4°F to +104°F. On centrifuges with a
heating/cooling option, the temperature set-point is settable from -20°C to +90°C / -4°F to +194°F. The lowest
obtainable temperature is dependent on the rotor (see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and
accessories").
30.1

Standby-cooling

When the rotor is at a standstill and when the lid is closed, the centrifugal chamber is cooled down to the preselected
temperature if this is lower than 20°C / 68°F.
During the standby cooling, the preset temperature is displayed.
