Accessing The Rotor In Case Of Power Failure - Beckman Coulter Avanti J-20 XP Instruction Manual

ACCESSING THE ROTOR IN CASE OF POWER FAILURE

Action
1. Turn the power switch to off
(O) and unplug the power
cord from the main source.
WARNING
Any maintenance procedure requiring
removal of a panel exposes the operator to
the possibility of electrical shock and/or
mechanical injury. Therefore, turn the power
off (O) and disconnect the instrument from
the main power source, and refer such main-
tenance to qualified service personnel.
!
WARNING
Before performing this procedure, verify that
the rotor is not spinning by listening carefully
for any noise coming from the chamber.
Proceed only if the instrument is quiet. Never
attempt to override the door interlock system
while the rotor is spinning.
If the facility power fails only momentarily, the centrifuge will
resume operation when the power is restored and the rotor will return
to the set speed. In the event of an extended power failure, it may be
necessary to override the door-locking mechanism manually to
remove the rotor and retrieve your sample.
To access the door-locking mechanism, you must remove the centri-
fuge front panel. Two latches secure the front panel in place; these
latches are accessible through two holes at the upper right and left
of the panel (see Figure 4-1).
