Model 642E has a true “0 RPM” lid locking system. The lid safety locking
system keeps the lid locked at all times when the rotor is in motion (even
during power failure). The centrifuge will not allow entry into the rotor
chamber unless the centrifuge has power and the rotor is stopped. To
open the lid, make sure that the centrifuge is plugged in and, with the
rotor stopped, press the ‘OPEN / STOP’ button.
Note: After the centrifuge has started spinning, it may be possible
to rotate the lid knob enough to cause the pawl to lose contact
with the lid safety switch. If this happens, the centrifuge motor
may lose power, but the lid will still remain locked. If the knob is
accidentally moved and this situation should occur, rotate the
knob fully clockwise to its stop position and the centrifuge will
resume operation.
Circuit Breaker: The Model 642E is protected with a 4 Amp circuit breaker
located at the rear of the machine mounted to the base. Any electrical
short circuit will cause the breaker to cut power to the machine.
