Getting Access To The Sample - Beckman Coulter Optima XPN User Manual

Maintenance and Troubleshooting
Retrieving Your Sample in Case of Power Failure
If the rotor has stopped spinning when power is restored, the instrument cancels the run and sends
a diagnostic message to alert you to that the run was cancelled due to a power failure.

Getting Access to the Sample

If a power failure lasts for several hours, you may have to remove the sample from the rotor while
there is no power to the instrument. The procedure requires removing the front panel, which
should be done only by qualified service personnel.
WARNING
Any maintenance procedure requiring removal of a panel exposes the operator to
the possibility of electrical shock and/or physical injury. If any such procedure
becomes necessary, turn the power switch OFF, and then disconnect the
instrument from the main power source by removing its power plug from the
receptacle. Refer the maintenance to qualified service personnel.
To get access to the rotor, follow these steps:
• Disconnect the power by removing its power plug from the receptacle.
• Remove the front panel.
• Vent the chamber to release the vacuum.
• Release the door lock.
• Open the door.
WARNING
The following procedure should be performed only when absolutely necessary and
only by qualified service personnel.
Check Power
Check that the power switch is in the OFF position and the instrument is disconnected from the
power (i.e., the power plug is removed from its receptacle).
Remove the Front Panel
To remove the front panel:
1
Locate the three front panel latch screws and use a small flat-head screwdriver to turn each
latch screw counter-clockwise until each one is loose. Refer to

Figure 9.1.
