6. Troubleshooting
6.3 Opening the door during power outage
The door cannot be opened except when the centrifuge is powered on (POWER switch
on) and the rotor is stopped. If the door cannot be opened due to a power outage,
open the door according to the following steps. (Below are the illustrations about the
Velocity 15HR centrifuge.)
(1) Check that the rotor is not rotating.
■
Observe the rotor through the window of the door and check the halt of the rotor.
Listen carefully to make sure that no rotating sound is heard, because you might
think that the rotor does not rotate although the rotor rotates at a high speed. As
it might be difficult to observe the rotor through the window of the door due to
dew- drops and frost, listen carefully to make sure that no rotating sound is
heard.
■
Touch the centrifuge carefully to make sure that vibration is not felt on the
centrifuge.
(2) Remove the plug after turning off the POWER switch.
■
There is a plug at the right side of the centrifuge.
WARNING
:
●
Opening the door while the rotor is rotating is very dangerous. Never unlock the
door while the rotor is rotating.
!
WARNING
:
●
Before opening the door, wait more than six minutes until the rotor comes to a
complete stop.
!
WARNING
:
●
Be sure to turn off the POWER switch before performing this work. Otherwise it may
cause electrical shock hazards and the centrifuge may be damaged.
