Troubleshooting:

1. Problem:

The rotor does not spin freely.

Solutions:

• Make sure that nothing has fallen into the rotor chamber.

• If there is nothing obstructing the rotor, the motor may be damaged.

Contact your authorized dealer or The Drucker Company for further

assistance.

2. Problem:

There is 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 screw in the center of the rotor is snug.

• The motor may be damaged. Contact your authorized dealer or

The Drucker Company for further assistance.

3. Problem:

The centrifuge does not run or an error message is displayed

Solutions:

• Make sure that the centrifuge is getting power. Does the control panel come

on? Check the electrical outlet that the unit is plugged into. Check the

circuit breaker on the base near the rear of the centrifuge.

• If the unit is getting power, make sure that the lid latch is closed properly.

The latch is closed properly when the yellow ‘LATCHED’ indicator light is

illuminated.

• If the centrifuge stops soon after start-up and ‘ERROR’ is displayed on the

speed display, refer to the following table for fault information:

ERROR / SPEED

The centrifuge cannot reach full speed due to a problem with the rotor, an

inadequate power supply, or other electrical problems. Press the OPEN/

STOP button to cancel the error and then check the rotor and the line

voltage. Contact your authorized dealer or The Drucker Company.

ERROR / BALANC

The centrifuge has detected an imbalance. Press the OPEN/STOP button to

cancel the error and balance the load. If the load is balanced, make sure

that the centrifuge is installed on a secure, level location.

4. Problem:

The lid knob cannot be turned / the lid cannot be unlocked.

Solutions:

• Make sure the centrifuge has power and that the rotor is stopped. Press the

‘OPEN/STOP’ button. The red ‘UNLOCKED’ indicator light should illuminate

and the unlocked mechanism should disengage, allowing entry into the lid.

• If the lid is still locked, make sure that the red ‘UNLOCKED’ indicator is

illuminated and turn the lid knob first completely clockwise and then

counterclockwise.

• If the red ‘UNLOCKED’ indicator will not illuminate or the locking

mechanism will not disengage, the electronics or locking mechanism may

be damaged. Have a technician service the centrifuge or contact The

Drucker Company for further assistance.
