Start-up Condition How to set this condition up
Non-Auto Start
When Cryojet is switched on the
gas flows are zero and automatic
temperature control is OFF.
Set the temperature control off by pressing the
OFF button on the left-hand side of the front
panel.
Use the STORE function: press and hold the
recessed button CAL/STORE using a pointed object
and press the SET button in the left-hand group of
buttons. The letters “Stor” will appear on the
display.
(This will interrupt the flow momentarily).
Now return the controller to Automatic
temperature control mode for normal operation.
Auto-Start
Sample flow and shield flow start
as soon as Cryojet is turned on,
with automatic temperature
control.
When the controller is switched on
it will display the message “Auto”
if it is in Auto-Start mode.
See Figure 2.
Auto-Start is useful if there is a possibility of brief
power failures when the Cryojet is running
unattended.
Do not select Auto-Start
unless you are sure that there will be
liquid nitrogen in the dewar when the
controller is switched on.
