Minimum Purge Volume
This setting is important when purge is set by time,
which is true when integrated color change is turned
on. If the minimum purge volume of solvent does not
flow through the solvent valve during the allotted purge
time, a “Purge Not Completed” alarm will occur.
Maximum Purge Time
This setting is important when purge is set by volume.
If the set volume of solvent does not flow through the
solvent valve by the time the maximum purge time has
elapsed, a “Purge Time Out” alarm will occur. This
alarm could indicate a meter or solvent supply prob-
lem.
