Use the monitor as the evidence page for external-controller testing.
The Control Quality Monitor should help the engineer judge what the controller requested, what the compressor answered, when warnings or faults appeared, and whether recovery happened correctly.
Main uses
- Trend the active engineering points.
- Compare multiple compressors during one scenario.
- Keep standard signal presets running.
- Capture event timing.
- Export a session report.
Recommended workflow
- Select the compressors involved in the test.
- Start a named test session.
- Choose the presets needed for the scenario.
- Run the controller sequence.
- Watch event timing, limits, and trend relationships.
- End the session and export the report.
Preset guidance
Preset logging should stay active once started. Preset buttons should act as a view filter, not as a destructive switch that stops other active preset traces.

What to watch during a run
Startup quality
- Demand applied
- State changes from idle to starting to running
- RPM rise and power rise
- Initial suction and discharge response
Protection quality
- Warning before fault where applicable
- Visible limit crossing for superheat limits
- Fault latch and reset behavior
- Return from fault to normal state when safe again
Session and report use
A good report should let another engineer understand what was tested, which compressors were active, which conditions were applied, what warnings and faults occurred, and whether the result was pass, watch, or fail.
PASS
WATCH
FAIL
Useful next additions
- A session summary card showing worst warnings, trips, and reset count
- Scenario scoring for startup time, stability, and protection-sequence quality
- Report sections that compare expected versus observed sequence timing
- Saved preset templates per compressor family or project
