5. TEST BENCH MAINTENANCE
To ensure a longtime unfailing performance of a compressor and its objective health assessment,
the Test Bench runs self-diagnostic checks and evaluates the condition of its main components
on a regular basis. During its operation the following messages can be displayed:
• «HP pressure is too low!» (Fig.30). This message appears when the bench operates in autotest
mode and the operator didn’t turn the valve off prior to launching “Productivity Test” or “Noise
Test”.
