Troubleshooting

and Maintenance

4-1

This section lists possible malfunctions, together with probable
causes and corrective actions. Maintenance procedures are also
described. Refer to the applicable rotor manual for instructions on
the care of rotors and accessories. Troubleshooting and maintenance
not covered in this manual should be handled by Beckman Coulter
Field Service.

➠

NOTE

It is your responsibility to decontaminate the
instrument, as well as any rotors and/or accesso-
ries, before requesting service by Beckman
Coulter Field Service.

IN CASE OF POWER FAILURE DURING THE RUN

If a power failure occurs during the run, the rotor begins to decelerate
with the brake off. If the rotor is still spinning above 1000 rpm when
power is restored, the instrument will resume operation and the
rotor will return to set speed with maximum acceleration. A PWR
diagnostic message will appear to alert you that a power outage
occurred.

If the rotor is spinning below 1000 rpm or has stopped when the
power is restored, the run automatically restarts. If the instrument is
in the TIME mode, it will automatically reset the TIME display to the
original set time. In the HOLD mode, the instrument will return to set
speed and elapsed time will begin to accumulate again from zero. A
PWR diagnostic message will appear to alert you that a power outage
occurred and that the run has been restarted automatically.
