Emergency recovery from power failure

Emergency recovery from power failure
1. Rotation of the rotor
The rotor stops as a result of free coast. However, if the rotor did not decelerate to 300 rpm or lower
when a power failure occurred, it will, or lower when a power failure occurred, after power returns,
automatically accelerate again and return to the set speed before the power failure. If the speed goes
below 300 rpm, the rotor will decelerate and stop after power returns.
If the rotor is stopping when the power returns, this micro-ultracentrifuge does not accept the
VACUUM button etc. (see
2. Touchscreen display

the settings specified before the power failure. (The settings have battery-backed back-ups.)
