2.4.3 System Wellness and Predictive Performance
System Wellness monitors the overall “health” of a chromatographic
system. It provides built-in diagnostic and calibration features that help
prevent unscheduled system shutdowns and assure reliable operation of
system devices. For details about System Wellness, see Section 5.1
.
Predictive Performance provides functions for monitoring the usage of
replaceable parts and for planning service procedures. Predictive
Performance lets you monitor the following functions:
• The number of hours the ICS-900 has been in use
• The number of times the injection valve has cycled
• The number strokes performed by the pump pistons
• The estimate of the amount of wear to the piston seal
• The volume of eluent pumped through the suppressor and column
You can set limits for injection valve cycles, piston strokes, piston seal
wear, suppressor usage, and column usage. Two limits can be set for each
parameter. When the first limit is reached, a warning message is displayed
in the Chromeleon or Chromeleon Xpress Audit Trail. When the second
limit is reached, an error message is displayed in the Audit Trail. After
replacing a part, reset the limit counters to zero.
Different applications cause different rates of wear on the consumable
parts in your instrument. Experience will help you determine the
appropriate limits to set to predict when the next maintenance will be
required.
Predictive Performance commands and parameters are available in the
Commands dialog box in Chromeleon or Chromeleon Xpress. To open
the Commands dialog box, press F8. Expand the list of commands under
Pump_ECD and scroll to the Predictive Performance commands
