Activate or deactivate the integral RCF display
The integral RCF display is activated or deactivated as follows when the rotor is at rest:
The setting can only be made via the operating unit (key position "0" or "LOCK 2"). The functions of the
various key positions are described in the "Key-operated switch" chapter.
You can scroll backwards through the menu by pressing the
T/°C
key.
The operation can be cancelled at any time by pressing the
OPEN / STOP
key. In this case, the settings are not
stored.
Keep the
PROG
key held down for 8 seconds.
After 8 seconds,
Machine Menu
appears in the display.
Press the
PROG
key as often as necessary until the
->Settings
is displayed.
Press the
START
key. The
SOUND / BELL = off/on
is displayed.
Press the
PROG
key as often as is required until
RCF Integral = off/on
is displayed.
Use the adjusting knob to set
off
or
on
.
off
= integral RCF is deactivated,
on
= integral RCF is activated.
Press the
START
key to save the setting.
Briefly,
Store Settings ...
is displayed as confirmation, followed by
-> Settings
.
Press the
OPEN / STOP
key once to exit the "Settings" menu or press the
OPEN / STOP
key twice to exit the
"Machine Menu".
23 Emergency
Stop
An Emergency Stop can only be executed via the operating unit (key position "0" or "LOCK 2") or via the
interface (key position "LOCK 2"). The functions of the various key positions are described in the "Key-
operated switch" chapter.
Press the
OPEN / STOP
key twice.
During a not-stop, run-out is carried out with braking level 9 (shortest run-out). Braking level
9 is displayed. If
braking level 0 has been preselected, run-out is carried out with braking level
9d. With braking level 9d, the run-out
time is longer, technically speaking, than braking level 9.
24 Cycle
counter
The settings can only be made via the operating unit (key position "0" or "LOCK 2"). The functions of the
various key positions are described in the "Key-operated switch" chapter.
Usage of the cycle counter only makes sense if you always use the same hanger set.
The centrifuge is fitted with a cycle counter, which counts the rotor cycles (centrifugation runs) of the different rotor
codes (see also chapter, "Rotor recognition").
In the swing-out rotors, the cycle counter is used to determine the rotor cycles (centrifugation runs) of the hangers.
If a rotor is recognized the first time, the centrifugation run is canceled. After pressing any key,
Enter max cycles =
30000
is displayed. The maximum permitted number of rotor cycles specified on the hanger has to be entered
before the centrifugation run can be restarted (see chapter "After starting the first centrifugation run, enter the
maximum permitted number of rotor cycles or deactivate the cycle counter").
For rotors and hangers which are not labelled with the maximum permissible number of running cycles, the cycle
counter can be deactivated (see chapters "After starting the first centrifugation run, enter the maximum permitted
number of rotor cycles or deactivate the cycle counter" and "Activating or deactivating the cycle counter").
Each time the lid is opened, the number of rotor cycles (centrifugation runs) of the current rotor code is displayed,
e.g.
CYCLES 5120 of 30000
.
If the entered maximum permitted number of rotor cycles of a hanger is exceeded, the message
MAX CYCLES
PASSED
is displayed after every start to the centrifugation run and the centrifugation run has to be restarted.
If
MAX CYCLES PASSED
is displayed, the hanger has to be replaced with a new hanger for safety
reasons.
After replacing the hanger, the cycle counter has to be reset to "0" when the rotor is at rest (see chapter "Reset cycle
counter to "0" and enter maximum permitted number of rotor cycles").
