Waters Prep Series Installation And Maintenance Manual page 25

During startup, the controller automatically runs self-diagnostic tests and
then displays the Startup screen.
Startup screen
The Startup screen lists the diagnostic status, controller configuration, and
software version number.
Diagnostic tests
The PrepLC controller is shipped as a PowerLine controller. Accordingly, the
Startup screen appears in PowerLine mode.
The self-diagnostics test each PowerLine module in the Waters Prep Series.
These modules include:
• Controller and pump
• Detectors (e.g., Waters 2487 or 2414)
• Autoinjector (Waters 717plus)
If all tests run successfully, the Startup screen indicates the diagnostic status
is "OK."
If any of the tests fail, the Startup screen displays a failure message.
Controller or pump failure
If the controller or pump fails the diagnostics test, the Startup screen names
the failed test. Turn the controller off, then on again. If the diagnostics fail a
second time, call Waters Technical Service.
