1. Assembling and starting
Put the centrifuge on a plain and horizontal place. Then plug the main
cable into a wall socket capable to supply the centrifuge with about 6
amperes.
Caution: Use a safety type wall socket with a well grounded safety
contact! Do not use any other socket type!
The main switch is located on the right side of the front panel. Switch
the centrifuge on by pressing it. After approx. 2 or 3 sec. the display is
lighting. Now press key "STOP/OPEN" and the lid locking is set free.
Then switch off the centrifuge by pressing again the main switch. Open
the lid and remove all packing material used for protecting the motor
during transportation. Possible residues of adhesive tape have to be
removed.
Put the desired head on the motor spindle and fasten it by the tommy
screw and the washer. The tommy screw should be fastened strongly
by hand (but without a tool).
2. Using the centrifuge

The temperature can be adjusted in steps of 0,5 °C and the centrifuging
time in minutes. All settings are non-volatile. They remain stored even
in case the centrifuge is switched off or the mains cable is disconnected.
All settings can be made only when centrifuge is in standby (not while
centrifuging).
2.2.2. Setting to operation
After having assembled and prepared the centrifuge according to point
1 of this manual the display is showing the desired speed (revolutions
per minute), the actual temperature (in oC) and the desired centrifuging
time by the active mode. Take care that the device is set up according
to the desired analysis method, i.e. the values (as per point 3) are set
properly.
2.2.3. Start of centrifuge
Attention: Recheck the right fastening of the tommy screw !
The test bottles have to be placed symmetrically to avoid unbalances.
Afterwards the lid is closed and pressed down until an audible catching
can be heard. Then press the key START and start centrifuging.
In case the lid was erroreously closed and the centrifuge has not yet
started it can be opened by pressing the key STOP/OPEN.
At the end of centrifuging time the centrifuge is braking and opening
the lid locking. The braking time depends on the speed. It is between
about 15 sec. (at 600 rpm) and 25 sec. (at 1100 rpm) Braking times are
preset.
The centrifuge switches off automatically in case it is out of balance and
the free moveable motor is touching the housing.
Hint: On account of safety reasons every switching off due to unbalance
is followed by a braking. Same is done in case of a coarse knocking on

the centrifuge. In order to stop the centrifuge by hand press the key
START a second time.
Hint: The centrifuge can only be started with lid locked and in case it is
not in the setting modus.
Attention: The centrifuge bowl is to be kept always clean. In case
glasses were broken it should be cleaned immediately
3. Settings
3.1. Setting of Speed
First press key "RpM/g". Then use the keys marked with arrow to find
the new desired speed.
The desired speed is variable between 600 and 1130 rpm in steps of 10.
Press the key "RpM/g" a second time in order to store the desired value.
3.2. Setting of Temperature
First press key "°C". The display is showing the set temperature. It can
be altered by the two keys marked with arrow.
By pressing the key "°C" a second time the desired temperature is
stored and the display is showing again the actual temperature.
Notice! During standby the centrifuge reduces the heating to avoid local
overheat. The amount of reduction is 10 °C.
3.3. Setting of Centrifuging time
First press key "TIME". By using the two keys marked with arrow the
new desired time can be set.
By pressing the key "TIME" a second time this setting is stored.

4. Informations about using
Following some questions and answers that may occur.:
- How to charge head A?
Head A has 36 places. When using butyrometers of measuring method
(1 stopper) all 36 positions can take a butyrometer. When centrifuging
butyrometers of weighing method (2 stoppers) or Babcock bottles max.
18 positions can be used (every second one).
- What is happening when centrifuge starts and brakes?
The centrifuge need approx. 30 sec. for reaching 600 rpm and up to 70
sec. for reaching 1100 rpm with head A fully loaded. Due to
construction a higher speed than the set one is not possible - neither
when starting nor when centrifuging.
The brake is electrically activated and therefore smooth and nearly
shock-free.
- How is the heating acting?
The heating is only active at a desired speed of 1000 rpm and above
regardless whether centrifuge stops or is running. At the beginning at
least 30 minutes are necessary for reaching 65 °C.
Notice! During standby the centrifuge reduces the heating to avoid local
overheat. The amount of reduction is 10 °C.
- How to open centrifuge at failure of current supply?
On the bottom side of the front part there is a black cap. In case of
emergency loosen this cap by a sturdy screw driver and pull the cord
fastened inside.
Attention! This should be done only in case of emergency. The cap is
mostly destroyed after it and has to be exchanged. Using the centrifuge
User Manual SuperVarioN
Page 8 of 15 Issue dd. 28.07.2004
with cord lying open is forbidden.
- Why is the last decimal point of temperature lighting
sometimes?
This lighting point indicates that heating is actually activated.
- Centrifuge does not correspond to key START. What may be
the reason?
The lid locking is not wholly catched. Press again. The catching can be
heard. When the centrifuge is braking no key can be used. This is a
fact.
Further, the centrifuge cannot be started while setup is in process.
(please see point 2.2.1).
- After start centrifuge brakes immediately. What may be the
reason?
The centrifuge is not placed horizontally or is unbalanced. This can be
tested by holding the tommy screw and moving the freely mounted
motor slightly into all directions. There should be a space of 3 to 5 mm.
- Are there fuses and are they exchangeable?
Yes, the centrifuge has one (from 2/95 two) main fuse (6,3 ampere,
delay action) and a fuse for the electronics (0,16 ampere, medium delay
action). Both fuses are mounted on the print board in the lower part of
the centriuge.
In order to exchange the fuses the centrifuge is to be disconnected
from the mains and to be put gently on its side. Then the base plate
can be screwed off (6 screws). Now the fuses are accessible.
- While setting the centrifuge sometimes only points are
visible. What is the meaning of that?
When the centrifuge features are to be set up and one of the keys

User Manual SuperVarioN
Page 9 of 15 Issue dd. 28.07.2004
"RpM/g", "oC" or "TIME" are pressed the displays show
to indicate the start of setting modus. Quitting the setting modus will
not activate the points.
- Immediately after switching on the centrifuge displays "br.."
and startes to brake. Why this?
The centrifuge was previousely interrupted while centrifuging or braking
- maybe by failure of power. On next startup it performs at first a
noninterruptable brake (for security). This takes about 30 seconds. After
that the lid can be opened.
- Which speed is requested for the customary analyses?
For Gerber - method set the speed to 1100 RpM.
For method according to Roese - Gottlieb (Mojonnier tubes) set the
speed to 600 RpM.
For ADMI - methode set the speed to 900 RpM.
That values are valid only in connection with the appr. heads:
*Head A for Gerber / 1100 UpM
*Head B for Roese-Gottlieb / 600 UpM
*Head C for det. of solutibility / 900 UpM
The main point in centrifuging is the effective RCA (Relative
Centrifugal-Acceleration). This depends not only on the speed, but also
on geometric properties, on kind and dimension of the used head.
