      Information

      Overview Manuals Common Applications Product Precautions
      Emerson A6220 is a dual-channel eccentricity vibration monitor for slow-roll and rotor eccentricity measurements in the AMS 6500 Classic system. It processes compatible eddy-current sensor signals over a low-frequency measurement band.
      • Measures low-frequency rotor eccentricity on two channels
      • Supports peak-to-peak, minimum and maximum processing
      • Supplies compatible eddy-current sensor systems
      • Provides continuous gap and 0/4–20 mA outputs

      Retain the slow-roll reference, peak-to-peak scaling and continuous-gap setup when replacing A6220. Verify both sensor gaps and test the configured minimum, maximum and eccentricity outputs at a controlled shaft condition.

      Important Notice: Verify A6220 from the physical marking and current manufacturer documentation before installation or configuration.

      Important Notice: Use these model-specific records together with the current manufacturer publication and the installed-system documentation.

      Slow-roll eccentricity testing
      Quantifies rotor bow during turning-gear operation.
      Turbine startup monitoring
      Tracks eccentricity as speed rises from slow roll.
      Rotor storage checks
      Compares minimum and maximum shaft position during controlled rotation.
      Eccentricity channel replacement
      Restores a two-channel A6220 without changing the recorded reference setup.
      Read the applicable Emerson instructions before work. Verify A6220 and the installed system configuration.
      1
      Verify A6220 and both eccentricity probe locations.
      2
      Place affected startup and protection functions in maintenance state.
      3
      Record slow-roll reference, probe gaps and shaft rotational condition.
      4
      Preserve peak-to-peak, minimum, maximum and continuous-gap settings.
      5
      Handle the monitor with ESD controls.
      6
      Confirm -26.7 VDC nominal sensor supply before reconnecting probes.
      7
      Check the 0/4–20 mA load is below 500 Ω.
      8
      Perform a controlled slow-roll comparison and prove enabled alarms before release.

      FAQS

      • What frequency band is processed by Emerson A6220?
        The official card reference gives an input band of 0.017–70 Hz for eccentricity measurement.
      • Which values can Emerson A6220 calculate during slow roll?
        A6220 provides peak-to-peak eccentricity, minimum position, maximum position and continuous gap.
      • What sensor supply is provided by Emerson A6220?
        The nominal supply is -26.7 VDC at 20 mA, with 35 mA maximum.
      • Which probes are supported by Emerson A6220?
        The card reference lists PR6422, PR6423, PR6424 and PR6425 systems.
      • What is the largest documented Emerson A6220 measurement span?
        The largest stated range is 0–8000 mV peak; the smallest is 0–400 mV peak.
      • What load limit applies to the Emerson A6220 current output?
        The 0/4–20 mA output requires a load below 500 Ω.
      • Why is slow-roll condition recorded for Emerson A6220?
        Eccentricity depends on rotor condition and rotational reference, so a different turning state can change the minimum, maximum and peak-to-peak result.
      • How is Emerson A6220 accepted after replacement?
        Confirm sensor supply and gaps, rotate under a controlled slow-roll condition, compare minimum/maximum/peak-to-peak values and prove outputs and enabled alarms.
