Imbalance detection

In case of the rotor not being equally loaded, the drive will turn off during acceleration. The rotor will decelerate to a
standstill.
When in the display "Time" (A-3) the word "error" (M11) together with the number "01" appear, the weight
difference of the samples is too large. Weigh the samples more exactly and start again.
Load the rotor as described in chapter 3.1.2 and 3.1.3.
When inside the display "Time" (A-3) the word "error" together with the number "02" (See figure 31) appear, it
could be due to the imbalance switch being defective.

SETTING

4.1

Change the type of rotor

Before the first operation and after each rotor change, you have to set the rotor type. You find each rotor type in the
printed order number on the rotor.
Example:
Angle rotor order number: 30130877
Rotor Type on the display = 77
Turn on the centrifuge and open the lid. Now simultaneously press the keys "Door Open"(7) and "Stop"(10). In
the display "RPM | RCF" the old rotor type no "77" appears. With the potentiometer you can now set the rotor type.
To store the new setting please press the "Start" (9) key. Inside the display, "Store" appears as confirmation.
Now all important rotor parameters for the centrifuge are stored.
Attention!
The set rotor type must always be the same as the actual rotor type used; otherwise the equipment
might be damaged.
The rotor type can be checked during the run by pressing the key "Door Open"(7).
