5.2 Survey of possible error messages and their solutions

5.2.1 Lid release during power failure (Emergency Lid Release)

The OPEN button suddenly fails due to shutdown as a result of power failure or due to shutdown as a result of
the burnout of fuse of the instrument. In order to protect the centrifuge sample, a pull ring is set at the bottom of
the instrument. Please pull the pull ring downward, the door lock will be opened, and the door cover can be
pushed open. However, the following rule-breaking operations are strictly prohibited.
(1) In the case the revolutions per minute of the instrument is not reduced to 100r/min during speed reduction
and shutdown, it is strictly prohibited to pull the pull ring at the bottom of the instrument to forcibly open the door
lock and manually force the rotor to stop operation, as which will cause personal injury.
(2) It is strictly prohibited to manually turn off the power switch and then turn on the power to press the OPEN
button to open the lid and force the rotor to stop by hand at the point when the program of the instrument
considers that the revolutions per minute is 0.

5.2.2 Description of the error message system

When operates the instrument improperly or a failure occurs, an error code will appear in the "Time" window.
See the following table for information about error codes.
