Troubleshooting:
NOTE:
The latch must be turned completely clockwise to its stop position in order
for the centrifuge to operate.
1. Problem:
The rotor does not spin freely.
Solutions:
– Make sure nothing has fallen into the rotor chamber.
– If there is nothing obstructing the rotor, the rotor may be damaged.
contact Drucker Diagnostics for further assistance.
2. Problem:
Excessive noise when the machine is running.
Solutions:
– Check to see that the load is balanced.
– Make sure that nothing has fallen into the rotor chamber.
– Make sure that the nut in the center of the rotor is tight.
– Have a technician test the motor and replace it if necessary.
3. Problem:
The centrifuge does not run.
Solutions:
– Check the electrical outlet.
– Make sure the lid latch is turned completely clockwise to its stop
position. When the lid is closed properly, the latch light on
the control panel will illuminate.
– Check the circuit breaker switch at the bottom left of the machine.
If the switch is white, the breaker has tripped. Contact Drucker
Diagnostics for further assistance.
– The printed circuit board may be damaged. Have a technician test
and replace the circuit board if necessary.
4. Problem:
The latch light does not come on when the lid is closed.
Solutions:
– Make sure that the unit has power.
– Make sure the lid latch is turned completely clockwise to its stop
position. The latch makes contact with a switch underneath the
front top of the cabinet. If this switch is not activated, the light will
not turn on and the machine will not run.
5. Problem:
The machine does not unlock after a run has completed.
Solutions:
– The lid should remained locked until the rotor has nearly come to a
complete stop and then unlock for 60 seconds. If additional unlock
time is needed, press the 'OPEN / STOP' button with
the machine plugged in and the rotor stopped. If the lid remains
locked after this and will not unlock, the electronics may have been
damaged. Contact Drucker Diagnostics for assistance. To
access the rotor chamber, follow the procedure on page 11,
"Emergency Rotor Chamber Entry".
6. Problem:
The run time is not set to the desired length.
Solutions:
– Check the run preset by following the instructions on page 5. If
the preset is not the desired length follow the procedure on the
same page to change the run preset time.

Setup Location:

1.
Unpack the centrifuge and verify that all of the supplied equipment is present.
2.
Choose a setup location which meets the following criteria:
a)
A bench top clearance height of 20" is required in order to open the lid.
b)
The clearance envelope is the space around the centrifuge which is
required for safety. Choose a setup location which will allow for a clearance
envelope of at least 24" x 24", (with the centrifuge at the center). No person
or hazardous material shall be permitted in the clearance envelope during
operation. The operator time within the envelope shall be limited to the time
necessary for loading, unloading and centrifuge operation only.
.
c)
Proper ventilation is necessary to prevent the overheating of samples as
