TROUBLESHOOTING
Malfunctions due to operating error or other problem can result in unnecessary machine down-
time and should be corrected as soon as possible. The troubleshooting procedures presented in
this section will assist technicians in isolating and correcting malfunctions.
Troubleshooting Procedure
Fault analysis should proceed logically from the simplest cause to the more complex. The most
difficult problem is an unexpected shutdown or inability to start. Always eliminate obvious causes of
malfunction before proceeding to more complex possibilities. Since more than one cause may be
responsible for a malfunction, the technician must proceed methodically to eliminate all possible
causes and take all corrective actions at each step of the troubleshooting process. Where changes
to operating procedures are the best course of action, appropriate recommendations are included.
In general, an unexpected centrifuge shutdown is due to an interruption of electric power that has
turned off the drive motors. Safety components are installed in key areas of the centrifuge electrical
control system to shut down the bowl and conveyor motors if safety parameters such as motor
temperature, vibration, or conveyor torque are exceeded. The power interruption may be due to one
or more factors, including a local power failure.
