Troubleshooting:

Solutions:
Problem:
The rotor does not spin freely.
Solutions:
– Make sure nothing has fallen into the rotor chamber.
– If there is nothing obstructing the rotor, contact Drucker Diagnostics or further assistance.
Excessive noise when the machine is running.
Problem:
– Check to see that the load is balanced.
– Make sure that nothing has fallen into the rotor chamber.
Solutions:
– Make sure that the nut in the center of the rotor is tight.
– Have a technician test the motor and replace it if necessary.
The centrifuge does not run.
– Check the electrical outlet.
– Make sure the lid latch is turned completely clockwise to its stop position. When the lid is closed properly, the
Problem:
– Check the circuit breaker switch at the bottom left of the machine. If the switch is white, the breaker has tripped.
Solutions:
– The printed circuit board may be damaged. Have a technician test and replace the circuit board if necessary.
The latch light does not come on when the lid is closed.
Problem:
– 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
Solutions:
The machine does not unlock after a run has completed.
– The lid should remained locked until the rotor has nearly come to a complete stop and then unlock for 60 seconds.
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
Problem:
All LED indicators are blinking with 2 short audible beeps repeating continuously.(VES will display 'Imbalance Error')
Solutions:
- The imbalance detection threshold has been reached during the cycle indicating a full cycle was not completed.
- Check the balance of the load. Refer to BALANCED LOADS on page 7.
- If it is determined that the detection is too sensitive this can be adjusted by increasing the imbalance detection
threshold. Refer to page 6 for programming settings.
Problem:
The yellow and red LED indicators are blinking with 3 short audible beeps repeating continuously. (VES will display 'Motor Power Err')
Solutions:
- The electrical current to the motor has exceeded the allowable limit, indicating that the full cycle was not completed.
- Make sure that nothing has fallen into the rotor chamber preventing the rotor from spinning freely.
- If there is nothing obstructing the rotor, the motor may be damaged. Contact Drucker Diagnostics for further assistance.
Problem:
The yellow and green LED indicators are blinking with 4 short audible beeps repeating continuously. (VES will display 'Motor Error')
Solutions:
- The internal tachometer has either not sensed a speed, the sensed speed is out of range, or the wrong rotor is installed.
(NOTE: if the wrong rotor is installed the centrifuge will not run without reprogramming the rotor selection)
9.
- Verify that the rotor being used is programmed correctly in the settings. Reprogram the correct rotor selection if
necessary. Refer to page 7 for instructions.
- Remove the rotor following the instructions on page 7. Check to see that there is a small silver reflective sticker on the
exterior vertical wall of the rotor.
- If the reflective sticker is present on the rotor and the correct rotor is programmed in the settings, contact Drucker
Diagnostics for further assistance.
Problem:
The centrifuge cycle stops prematurely and the yellow LED indicator is blinking.
Solutions:
- This is an indication that the lid is not properly latched and the cycle has entered the "paused" state.
- Turn the knob clockwise to re-latch the lid and resume the cycle.
- If the cycle does not resume and the knob is fully turned, contact Drucker Diagnostics for further assistance.

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.
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 10,"Emergency Rotor Chamber Entry".
instruction on page 6 to change the run preset time.
For servicing information or additional technical support,
contact Drucker Diagnostics or your authorized distributor.
NOTE:
The lid latch must be turned completely
clockwise to its stop position in order for
the centrifuge to operate.
