The bayonet is designed to make a positive and secure connection to the sample carrier so that it remains
horizontal and in a straight line to connect with the carrier adapter within the specimen chamber.
Gate Valve
The Gate Valve has positions that are defined by the following status:
•
rotated position of the Gate Valve Lever – LOCK / UNLOCK
The position has to be turned from LOCK to UNLOCK to be able to move the loading rod IN and OUT
•
colored strips on the side of the exposed barrel axis – one / two when IN / OUT
•
Position 1 – IN and LOCK
•
Position 2 – IN and UNLOCK
•
Position 3 – OUT and UNLOCK
•
Position 4 – OUT and LOCK (prevents vacuum closing valve).
The Gate Valve has two safety movements.
•
it can be placed over the entry hole on the slide
•
it can be locked in place by a turn of the connecting knob (securing the closure of the valve)
A system interlock takes care of correct conditions (system vacuum, accelerating voltage) for loading and
unloading cycles (movement of the gate valve).
Controls
There are 2 buttons (illuminated while in operation) and 1 indicator lamp:
•
P
(pump) labelled button – is pressed to pump the loader chamber to the required vacuum, the stage moves to a
loading position at the same time. If the system reaches appropriate vacuum level, the lever interlock is released
and the gate valve can be opened. The pump cycle is automatically terminated when the required vacuum is
reached.
•
V
(vent) labelled button – is pressed once to vent the loader chamber. The vent cycle continues till the
P
button
is pressed or it is terminated by time-out.
•
OK
labelled indicator lamp – lights up when vacuum is reached after pumping. When it goes out this means the
wait time has been exceeded and the appropriate vacuum for a transfer has been lost. Pressing the
P
button
again will bring the system to vacuum
OK
status.
Control buttons are not shining when the system is recovering from vacuum status transition (e.g. immediately
after the load/unload sample, during venting the chamber…). After finishing the state transition the control buttons
will be in operation again.
