Glove Box Evacuation (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 499
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 499 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/STOP,” 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 “START/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.
