Troubleshooting and Maintenance
RETRIEVING YOUR SAMPLE
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 and disconnect the instrument from the
main power source, and refer such mainte-
nance to service personnel.
WARNING
!
NEVER attempt to slow or stop the rotor
by hand.
WARNING
!
The following procedure should be imple-
mented only when absolutely necessary and
only by qualified service personnel.
If a power failure lasts for several hours, it may be necessary to
retrieve the sample from the rotor. (A rotor decelerating without the
brake may take hours to come to a complete stop.) To gain access to
the rotor, it will be necessary to remove the control head cover and
the front panel to disengage the door lock.
1. Locate the two metal latches (see Figure 4-1) at the lower outside
corners on the back of the control head. Use your fingers to
depress the latches to disengage the cover from the control head.
With both hands, lift it slightly and pull it toward you until it is
free. Set the cover aside in a safe place.
2. To remove the front panel, use a long, thin tool (about 1.5 mm in
diameter) to depress the latch (see Figure 4-2). While the latch is
depressed, use your free hand to lift the top panel until it stops,
remove the tool, then continue lifting the top panel to free the front
panel. Let the front panel tilt toward you.
3. Lift the front panel to free the bottom tabs that secure it in place.
