Troubleshooting

Accessing the Rotor in Case of Power Failure

WARNING

Any maintenance procedure requiring removal of a panel exposes the operator to

the possibility of electrical shock and/or mechanical injury. therefore, turn the

power off (

O) and disconnect the instrument from the main power source, and

refer such maintenance to qualified service personnel.

WARNING

Before performing this procedure, verify that the rotor is not spinning by listening

carefully for any noise coming from the chamber. Proceed only if he instrument is

quiet. Never attempt to override the door interlock system while the rotor is

spinning.

If the facility power fails only momentarily, the centrifuge will resume operation when the power is

restored and the rotor will return to the set speed. In the event of an extended power failure, it may

be necessary to override the door-locking mechanism manually to remove the rotor and retrieve

your sample.

To access the door-locking mechanism, you must remove the centrifuge front panel. Two latches

secure the front panel in place; these latches are accessible through two holes at the upper right and

left of the panel (see Figure 4.1).
