Using The 8550 Shatterbox; Operation Of The Safety Door - SPEX SamplePrep ShatterBox 8550 Manual

Operation of
the safety door
As mentioned above, the 8550 ShatterBox is equipped with a semi-automatic safety
door, which has a safety interlock to prevent the user from starting a grinding cycle
if the door is still open.
Automatic lock operation
When the user closes the door, an electronic system will engage mechanical locks,
so that the door cannot be accidentally re-opened.
Even in the case of a power failure, a mechanical lock will remain in place. When
turning the unit on (or after a power failure), the door will remain up, in locked
position. The display instructs the user to push the door further up to disengage the
lock, so that the door can slide down freely.
Electronic unlocking
When the user has closed the door, the grinding instrument assumes that it is ready
to start a grinding method and will keep the door locked.
In case the user wants to re-open the door before the grinding is started, simply
press on the "Door unlock" button:
The instrument then unlocks the door, which will then automatically slide down, in
an open position.
Manual override
When there is no power (e.g. when cleaning or packing the unit), it is possible to
override the locking mechanism to manually open the safety door. Locate the lock
override access hole (refer to page 5, General view) and use a thin tool such as a
small flat screwdriver to slide the locking mechanism to the left.
