9.3 RELEASING LID LATCH
If the lid is latched and there is a loss of main power to the centrifuge – i.e., an interruption of primary electrical
power – the lid will remain latched. A jammed plunger in the latch solenoid can also cause the lid to remain
latched. If you cannot wait for the restoration of power, the lid can be opened as follows:
a) Disconnect the Power Pack plug from
the centrifuge.
b) Turn the centrifuge upside-down.
Using a Flat-head screwdriver,
locate in the center: the emergency lid-
open slot.
c) Push gently on the end of the solenoid
plunger until the latch is released
(Figure 9-1, 9-2).
d) Turn the centrifuge upright. Reconnect the plug of the Power Pack to the centrifuge.
e) When the power problem is corrected, check by closing and latching the lid; then turn power on and off
to verify that the lid unlatches properly.
