9 Acceleration / Braking 9
17. The centrifuge should achieve the desired speed and then
slow down and stop without the following error message
appearing: The 15 gr imbalance must be tolerated.
Repeat the Low threshold check 3 times: Each cycle should

obtain an ideal ambient temperature as
described in manual.
The temperature set in the program is not
adapted. The settings for speed / temperature are not
compatible with a normal utilization.

down to a temperature between 4C and 37C
during 1 hour
The refrigeration doesn’t work. Contact a Certified Technician.

The difference between the air temperature
and the over temperature alarm set point is
greater than the set value. Check the value of the temperature alarm
threshold.
Change program settings: speed and/or
temperature.
04 MOTOR
OVERTEMPERATURE The motor temperature is too high. A « no-brakes » stop is occurring.
