2.7 Imbalance Detection

In case the rotor is not equally loaded, the drive will turn off, during acceleration. The rotor decelerates
to a standstill.
When in the display "time" (A-3), the word "error" (M11) along with the number "01" appears, the
weight difference of the samples is too large. Weigh out the samples exactly!
Load the rotor as described in Chapters: 2.1.2 and 2.1.3.
When inside the display "time" (A-3), the word "error" along with the number "02" appear, (see Figure
35), the potential reason for the error screen can be: The imbalance sensor is defective.

2.8 Timer Function

This timer function enables to program a planned ending or start of centrifugation. After closing the
centrifuge lid and setting all the needed values, the timer function can be activated.
For this purpose press the bottom „time" (6) for five seconds. This will take you to the time setting of
the timer and the display "rpm/rcf" (A-1) shows the words "End in". The display „time" (A-3) shows
the remaining time until the end of the centrifugation. The remaining time can be set between 1 min
and 99 h 59 min by pressing the bottom "time" (6) and turning the control field (1).
Alternatively to the "End in" mode, you can choose the "Start in" mode by pressing the bottom
„rpm/rcf" (4). The display „time" (A-3) shows the remaining time until the start of the centrifugation.
