Centrifuge address

Ex works, the address is ] = 29. Address is set.

Query the operating hours, centrifugation runs and cycle counter

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 query is performed as follows when the rotor is at a standstill:
You can scroll backwards through the menu by pressing the

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 all centrifugation runs is displayed, e.g. Number of Starts = 10.
PROG

Press the key. The number of rotor cycles (centrifugation runs) of the current rotor code since the last time
PROG
the cycle counter was reset to "0" and the permitted number of rotor cycles are displayed, e.g. CYCLES = 5120
of 30000.

Press the key. The number of all rotor cycles (centrifugation runs) of the current rotor code is displayed,
PROG
e.g. Rotor cycles total = 37490. This value cannot be set.

Press the key twice to exit the "Operating Time" menu or press the
OPEN / STOP
exit the "Machine Menu".

Query the system information

The following system information can be queried:

Centrifuge model

Mains voltage

Rotor information

Program version of the centrifuge

Program version of the frequency converter
The system information can be queried as follows when the rotor is at a standstill:
You can scroll backwards through the menu by pressing the

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 centrifuge model is displayed.
START

Press the key. The mains voltage is displayed, e.g. Mains Voltage : 230 V.
PROG

Press the key. The rotor code (Rotor), the maximum speed of the rotor (Nmax) and a centrifuging radius
PROG
(R) of the last rotor detected by the rotor detector are displayed. 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.
The required centrifuging radius must be set according to the used accessories; see chapter "Entering
centrifugation parameters".

Press the key. The program version of the centrifuge is displayed, e.g. SW version = V01.00.
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 exit the "Info" menu or press the
OPEN / STOP
"Machine Menu".

Immediate display of centrifugation data after switch-on.

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