Glove Box Purge/Fill – Operation Mode 2
The Glove Box Purge/Fill mode uses the same solenoid valves on the glove box that are used in
the Pressure Control Mode. The Pressure Control mode will be temporarily suspended while a
“Purge/Fill” command is being executed.
Note that this display screen looks similar to the Pressure Control mode described previously.
However, the “SETUP” key has changed to a “Cycles” key. Up to 199 cycles can be set for
automatic “Purge/Fill” of the glove box main chamber by holding the “Cycles” key. To decrease
the number cycles, press the “Cycles” key to 199 cycles and go around again until a lower cycle
quantity appears. Use this display screen to also set the low pressure level for purging and the
high pressure level for filling by adjusting the upper and lower limit keys. The Labconco
Pressure Controller allows the glove box Main Chamber pressure levels to be set to +/- 5 inches
of water column [+/- 12.6 mBar]. Once the pressure limits and number of cycles have been
selected, press the key adjacent to “Start,” and the automated purge and fill process will begin
and continue for the number of cycles selected. Each cycle number will be displayed during the
process. To cancel the automated purge and fill process, press the key adjacent to “Stop” and the
process will be stopped.
Note that when the “Glove Box Purge/Fill” mode is in operation, there are no keys available to
allow for system setup as the “Cycles” key replaced the “SETUP” key. Use the “Mode” key in
the upper left hand corner adjacent to the icon to return to the “Glove Box Pressure Control”
screen to use the “Select” mode.
