DISPLAY AND OUTPUT:
Liquid Usage Alarm can now be
“Enabled or Disabled” on software versions starting with
2.03. When this alarm is disabled, there will be no visual or audible indication at the
controller, but the event code for the alarm will continue to be recorded in the internal
data log. Since this alarm is the early warning to potential vacuum failure, it is
recommended that it not be disabled.
With software version 2.03 the liquid usage warning will no longer be indicated on the unit
either audibly or visually. It will only be recorded in the internal data log. This is to
minimize self-correcting nuisance warnings. A New menu page was added in the Display
and Output menu, after the Enable Liquid Usage Display page, to allow enabling /
disabling the liquid usage alarm.
