MERGENCY

In the event of power failure, it may be impossible to unlock the lid by

conventional means. In this case, entry into the rotor chamber may be

made by removing the latch label and using a

pen to manually disengage the locking

mechanism (see photo). Pull the mechanism

towards the control panel and then unlatch

and open the lid. If the unit is damaged,

contact your authorized dealer or Drucker

Diagnostics.

ALIBRATION

It is recommended that the top speed be tested every two years for

continued safe operation. Contact Drucker Diagnostics for further

information or testing availability.

AFETY

The Model 642B complies with US, Canadian, and European Safety standards.

Lid Safety Switch: The Model 642B lid is secured to the top of the cabinet

by a latching knob and pawl system. When the knob is rotated clockwise,

the pawl grips the underside of the cabinet opening and prevents the lid

from opening. A mechanical stop positions the pawl and prevents it from

rotating completely. When rotated to the stop position, the pawl makes

contact with a micro–switch mounted underneath the cabinet top. The lid

safety switch prevents the centrifuge from operating while the lid is open.

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. 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 642B 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.
