7. After termination, immediately after the rotor stops and the
door unlocks, open the chamber door and measure the
sample temperature using the same calibrated thermometer
that was used earlier.
The measured sample temperature should be within 2°C of SET
temperature. If required, repeat this procedure at other speed/
temperature ranges commonly used in your run protocols.
If an out-of-range temperature is observed, re-equilibrate the
chamber, rotor, and test fluid temperatures to match desired
sample temperature, and repeat the test run.
Emergency Sample Recovery
If a power failure (or malfunction that disables the door unlock
function at zero speed) occurs while the rotor is spinning, a means to
mechanically override the door interlock is provided to allow sample
recovery. This procedure should never be used routinely, or while the
rotor is spinning, and is intended for emergency sample recovery only.
Read the WARNING.
To perform the mechanical override (refer to Figure 5-1):
1. Turn the main power switch OFF, unplug the centrifuge, then use
the viewing port and make sure the rotor has stopped spinning
before proceeding.
2. Access the interlock motor, located behind the bezel that frames
Main POWER switch and KEYPAD LOCK panel in the upper
right side of the front cabinet panel. Remove the four screws that
secure the bezel, then remove the bezel.
W A R N I N G
Do not open the chamber
door when the rotor is spinning.
In the event of a power failure (or any
failure where RUN speed does not
register), the brake will not operate
and the rotor will coast to a stop –
from high speed, deceleration to 0
could take as long as 30 minutes.
Before using the mechanical override
to open the chamber door, use the
viewing port in the door to make sure
that the rotor has stopped spinning.
Opening a chamber door when a rotor
is spinning exposes hazardous
energy; contact with a spinning rotor
could cause personal injury.
