e. Front-Panel Controls. Front-panel controls include an illuminated power
switch, run-brake switch, automatic timer, adjustable speed control, and tachometer. You
can continuously adjust speed over the range of 500 revolutions per minute (rpm)
(minimum) to a specific maximum, depending upon the rotor and shield configuration
used.
f. Additional Safety Features. Additional safety features on the centrifuge
include a transparent, shatter-proof, polycarbonate cover equipped with a positive latch. A
latch interlock system prevents you from operating the centrifuge while the cover is open.
Once the cover is closed and latched and the centrifuge is operating, a zero speed control
switch prevents you from opening (unlatching) the cover until the rotor slows to less than 1
revolution per second. An external fuse, located on the back of the machine, prevents
damage to the centrifuge in the event of external power surges or internal shorts.
