Rotor recognition

Rotor recognition is carried out after each start of the centrifugation run.
If the rotor has been changed, the centrifugation run is canceled after rotor recognition. The rotor code (rotor), the
maximum speed of the rotor (Nmax) and the preset centrifuge radius (R) of the rotor being used are displayed, e.g.
Rotor 4 Nmax= 4500 R=184 mm .
If the maximum speed of the rotor being used is less than the set speed, the speed is limited to the rotor's
maximum speed. In this case, the program place number is displayed in parentheses ().

with refrigeration, precooling of the rotor can also be started by pressing the
If the cycle counter is activated, the number of rotor cycles (centrifugation runs) of the current rotor code
is displayed briefly when the lid is opened, e.g. ROTORCYCLES 5120 of 30000 (see chapter "Cycle
Counter").

Emergency release

During a power failure the lid cannot be unlocked by motor. An emergency release has to be executed by hand.
For emergency release disconnect the centrifuge from the mains.
Open the lid only during rotor standstill.
See figure on page 2.

Switch off the mains switch (switch position "0").

Look through the window in the lid to be sure that the rotor has come to a standstill.

Insert the hexagonal wrench key into the bore hole (Fig. 1, A) and carefully rotate by half a turn in clockwise
direction until the lid can be opened.

Pull the hexagon socket head wrench out of the drilling again.

Maintenance and servicing

The device can be contaminated.
Pull the mains plug before cleaning.
Before any other cleaning or decontamination process other than that recommended by the manufacturer is
applied, the user has to check with the manufacturer that the planned process does not damage the device.

Centrifuges, rotors and accessories must not be cleaned in rinsing machines.

They may only be cleaned by hand and disinfected with liquids.

The water temperature must be between 20 – 25°C.

Only detergents/disinfectants may be used which:
 have a pH between 5 - 8
 do not contain caustic alkalis, peroxides, chlorine compounds, acids and alkaline solutions

In order to prevent appearances of corrosion through cleaning agents or disinfectants, the application guide from
the manufacturer of the cleaning agent or disinfectant are absolutely to be heeded.
